Abstract: Despite the expanding scholarship on English for Specific Purposes (ESP), insufficient attention has been given to the pedagogical and curricular consequences of developing ESP for Business courses in contexts where textbooks are unavailable, unsuitable, or intentionally excluded. Much of the existing literature remains anchored in textbook-dependent models, thereby overlooking how curriculum design, instructional practices, and learning coherence are negotiated in textbook-free settings. Addressing this gap, this study investigates the pedagogical challenges and curriculum opportunities emerging from the design of an ESP for Business course at Universitas Cipta Wacana, a private Indonesian university. Adopting a design-oriented qualitative research approach, the study examined iterative processes of course planning, materials development, and instructional enactment over one academic semester. The participants comprised 38 undergraduate Business Administration students and two ESP instructors, selected through purposive sampling. Data were generated from instructional design artifacts, teaching reflections, learner feedback instruments, and focused interviews with instructors, and were subjected to systematic qualitative analysis. The findings indicate that the absence of a prescribed textbook fostered curricular adaptability, contextual authenticity, and closer alignment with disciplinary communication practices, while simultaneously generating tensions related to instructional consistency, assessment benchmarking, and increased cognitive and temporal demands on instructors. These findings highlight the dual pedagogical implications of textbook-free ESP design and suggest the need for institutionally supported frameworks to sustain innovation while ensuring curricular Keywords: curriculum development.

Introduction The flourishing growth of English for Specific Purposes (ESP) courses has increasingly gained scholarly attention due to its relevance in reconciling general English proficiency with the linguistic demands void in specific professional or academic domains (Nurmetov. BakiN-MiriN, & Chaklikova. ESP for Business, in particular, focuses on equipping learners with targeted communicative competencies required in the business environment, including business writing, negotiation, presentations, and professional correspondence (Dudley-Evans. , & St. John, 1998. Swales, 1. Previous studies have emphasized the importance of contextually tailored ESP curricula that reflect authentic workplace tasks and industry-specific language, highlighting that alignment between learner needs and instructional content is central to effective ESP pedagogy (Chan, 2019. Hidayati. Novianti. Khansa. Slamet, & Suryati, 2023. Slamet. Basthomi. Ivone, & Eliyanah, 2025. Despite these This is an open access article under the CCAeBY license. https://doi. org/10. 55210/attalim. At-Ta'lim: Jurnal Pendidikan, 12. , 2026, 137-156 Abd. Syakur. Yulianto Sabat. Ika Rahmania. Lailatul Musyarofa. Moh. Hilman Fikri insights, a predominant focus on textbook-based ESP instruction has been reported in multiple contexts, often constraining instructorsAo ability to adapt materials to local learner needs or emergent professional practices (KosoviN, 2025. Nguyen. Marlina, & Cao, 2021. Suwarno. Sulis, & Ashadi. Textbooks, while providing structural guidance and standardized content, frequently exhibit limitations in authenticity, flexibility, and responsiveness to learnersAo immediate learning goals, leading to a pedagogical tension between prescribed content and real-world applicability (Cheng. Han. Xian, & Li, 2025. Yang, 2. Consequently, the reliance on commercial textbooks may inhibit curriculum innovation and restrict instructor autonomy, highlighting the need to explore alternative approaches that enable adaptive and context-sensitive ESP course design. Curriculum development in ESP has been acknowledged as a complex, iterative process that requires careful integration of learner needs analysis, pedagogical strategies, and assessment practices (Ellederovy, 2022. Pramila et al. , 2025. Slamet. Basthomi. Ivone, & Eliyanah, 2025. The literature underscores that effective ESP curricula should move beyond mere language transmission to encompass task-based, learner-centered, and reflective practices that are dynamically responsive to professional or disciplinary demands (Hyland, 2022. Hyland & Jiang, 2021. Marcu, 2. Empirical research, however, indicates that the practical implementation of ESP curricula often faces significant challenges, including insufficient institutional support, limited teacher training in ESP-specific pedagogy, and scarce availability of authentic or contextually relevant instructional materials (Harwood, 2025. Martyn-Gonzylez & Chaves-Yuste, 2024. Meristo & Heero, 2. Moreover, assessment practices in ESP frequently emphasize generalized language proficiency rather than domain-specific competencies, creating misalignments between learning outcomes, classroom instruction, and professional expectations (Chan, 2021. Gimenez, 2. These findings suggest a need for integrative frameworks that not only incorporate targeted linguistic skills but also foster curriculum flexibility, learner autonomy, and alignment with discipline-specific professional Pedagogical challenges are further compounded in contexts where commercial textbooks are unavailable, inappropriate, or misaligned with local institutional and learner contexts. While textbookfree ESP courses provide opportunities for instructor-driven materials development and curriculum customization, they also introduce practical constraints, such as increased preparation time, the need for authentic materials curation, and potential inconsistencies in content delivery (Chan, 2024. Xie. Studies examining textbook-free ESP environments indicate that instructors must engage in iterative design processes, balancing theoretical principles, learner needs, and practical constraints, which can simultaneously enhance pedagogical creativity and exacerbate instructional complexity (Petraki & Khat, 2022. Tuzlukova & Heckadon, 2. Furthermore, research highlights that textbook absence necessitates proactive decisions regarding course sequencing, task selection, and assessment strategies, demanding high levels of instructor expertise and reflective practice (Alhassan. Ali, & Ali, yAvila-Cabrera & Corral Esteban, 2021. Dou. Chan, & Win, 2. Despite these insights, there remains a scarcity of empirical studies investigating the nuanced dynamics of textbook-free ESP course design, particularly how instructors navigate challenges while leveraging curricular opportunities to achieve learner-centered outcomes. The variables operationalized in the present study include pedagogical challenges, curriculum opportunities, and course design in textbook-free ESP contexts. Pedagogical challenges are conceptualized as instructional difficulties encountered in materials development, classroom delivery, and assessment alignment, while curriculum opportunities refer to the potential advantages of flexibility, contextualization, and learner-centered innovation that emerge when textbooks are not the primary instructional resource. Course design encompasses the integrated processes of curriculum planning, instructional enactment, and assessment implementation, reflecting both instructor agency and responsiveness to learner needs. Collectively, these variables provide a coherent framework to At-Ta'lim: Jurnal Pendidikan. ISSN 2460-5360 . | 2548-4419 . At-Ta'lim: Jurnal Pendidikan, 12. , 2026, 137-156 Abd. Syakur. Yulianto Sabat. Ika Rahmania. Lailatul Musyarofa. Moh. Hilman Fikri examine the dual dynamics of constraint and opportunity inherent in textbook-free ESP course Based on the identified gaps, this study seeks to answer the following research questions (RQ. What pedagogical challenges are encountered in the design and delivery of a textbook-free ESP for Business course? What curriculum opportunities emerge from the development and implementation of a textbook-free ESP for Business course? Literature Review ESP and Business English Pedagogy ESP has evolved as a distinct field in language education, emphasizing the alignment of linguistic instruction with the communicative demands of specific academic or professional domains (Albers. Vences, & Nickerson, 2020. Chan, 2. Within the realm of Business English, the focus extends beyond general language proficiency to include competencies in professional communication, negotiation, presentations, report writing, and cross-cultural interaction, reflecting real-world workplace demands (Chan, 2024. Gimenez, 2014. Xu. Chen. Wang, & Suhadolc, 2. Previous studies have highlighted that effective Business ESP courses require careful integration of industryspecific language, task-based activities, and authentic materials to ensure learners develop applicable skills . Avila-Cabrera & Corral Esteban, 2021. Tuzlukova & Heckadon, 2. However, much of the existing literature demonstrates a persistent reliance on commercially produced textbooks, which may not adequately address the dynamic and contextualized language needs of learners (Albers et al. , 2020. Chan, 2. While textbooks provide structure and a degree of standardization, their limitations in authenticity, flexibility, and responsiveness often constrain instructorsAo pedagogical creativity and hinder adaptation to learner-specific goals. Research indicates that such constraints necessitate alternative approaches that allow for contextualized content, iterative curriculum design, and reflective instructional practices, highlighting an important gap in the literature regarding textbook-free Business ESP pedagogy. Curriculum Design in ESP Contexts Curriculum design in ESP is a multifaceted and iterative process that integrates needs analysis, pedagogical strategies, materials development, and assessment alignment (Marcu, 2020. Pramila et al. Slamet et al. , 2025. The literature emphasizes that ESP curricula must be adaptable to learner characteristics, disciplinary conventions, and professional standards, ensuring that language instruction is meaningful, goal-oriented, and authentic (Albers et al. , 2020. Petraki & Khat, 2. Empirical investigations into curriculum design have highlighted both opportunities and constraints. On one hand, flexible curricula enable instructors to prioritize learner-centered tasks, integrate authentic materials, and foster professional language practices (Harwood, 2. On the other hand, research also indicates challenges in achieving coherence across instructional sequences, aligning assessments with specific learning outcomes, and ensuring consistency when materials are developed independently of standardized textbooks (Basturkmen, 2025. Iswati & Triastuti, 2021. Tuzlukova & Heckadon, 2. While several studies have explored ESP curriculum frameworks and task-based learning approaches, there is limited empirical evidence on the practical implementation of textbookfree curriculum design, particularly in Business English contexts. This gap underscores the necessity for research that examines how instructors navigate tensions between pedagogical flexibility, content coherence, and learning outcome alignment in the absence of structured textbook guidance. Pedagogical Challenges in Textbook-Free ESP Instruction Pedagogical challenges in ESP courses are amplified in contexts where textbooks are unavailable or unsuitable for local learnersAo needs. Literature has shown that instructors in such At-Ta'lim: Jurnal Pendidikan. ISSN 2460-5360 . | 2548-4419 . At-Ta'lim: Jurnal Pendidikan, 12. , 2026, 137-156 Abd. Syakur. Yulianto Sabat. Ika Rahmania. Lailatul Musyarofa. Moh. Hilman Fikri environments encounter increased demands in planning, materials selection, and instructional sequencing, as they must curate or develop authentic resources that align with both disciplinary requirements and learner objectives (Chan, 2024. Xie, 2. Studies highlight the dual nature of these challenges: textbook-free instruction offers opportunities for creative pedagogy, adaptive tasks, and contextualized learning experiences, yet simultaneously requires extensive preparation, continuous reflection, and strong content expertise (Albers et al. , 2020. Suwarno et al. , 2. The absence of prescriptive materials may also introduce inconsistencies in delivery, assessment, and learner engagement, posing risks to curriculum coherence and learning outcome reliability (Han et al. , 2025. KosoviN, 2025. Nguyen et al. , 2. Despite these documented insights, empirical research examining the nuanced strategies instructors employ to manage textbook-free pedagogy, and the ways they leverage challenges into instructional and curriculum innovation, remains scarce. Such investigation is essential to inform evidence-based frameworks for effective ESP instruction in resource-constrained or highly context-specific settings. Curriculum Opportunities and Innovation in ESP The literature on curriculum opportunities highlights the potential benefits of adaptive, textbook-free ESP instruction in enhancing contextual authenticity, learner engagement, and instructor autonomy (Han et al. , 2025. KosoviN, 2. By moving beyond prescribed textbooks, instructors can integrate real-world tasks, authentic business documents, and technology-mediated resources, fostering learner-centered and task-oriented learning environments (Pramila et al. , 2. Research also indicates that flexible curriculum design can cultivate professional communicative competence, critical thinking, and reflective learning practices, enabling learners to navigate complex workplace scenarios (Chan, 2019. Cheng, 2021. Nguyen et al. , 2. Nonetheless, while these opportunities are recognized theoretically, there is a limited body of empirical work demonstrating how textbook-free curriculum strategies are operationalized in practice, how instructors balance innovation with consistency, and how learning coherence is maintained across tasks and assessments (Basturkmen. Meristo & Heero, 2. This gap points to the need for systematic investigation into how curriculum opportunities are realized, negotiated, and sustained in ESP courses absent conventional instructional resources. Theoretical Framework and the Study Context The present study is grounded in design-oriented qualitative research principles, which prioritize iterative curriculum development, reflective practice, and context-sensitive pedagogical decision-making, enabling a systematic examination of how instructional interventions are conceived, implemented, and refined in authentic learning environments (Almquist & Lupton, 2010. Verschuren & Hartog, 2. The theoretical framework integrates ESP curriculum theory, emphasizing alignment between learner needs, disciplinary language requirements, and professional communication practices, with task-based learning principles that foreground active engagement in authentic business-related tasks, and authentic materials pedagogy, which highlights the use of contextually relevant and industry-specific resources to foster transferable skills (Dudley-Evans. , & St. John, 1998. Swales. John Swales, 1. This framework positions the interaction among instructor agency, curriculum design, and learner engagement as central to understanding how pedagogical challenges and curriculum opportunities are negotiated in textbook-free contexts. The study is situated in an ESP for Business course at Universitas Cipta Wacana, a private Indonesian university, selected due to its representative challenges of limited access to commercially aligned textbooks, diverse student proficiency profiles, and institutional flexibility allowing experimental curriculum interventions.

Hilman Fikri the nuances of curriculum innovation, instructional adaptation, and learner responsiveness. The insights generated are intended to be analytically generalizable to similar higher education ESP contexts, particularly in resource-constrained settings, by elucidating principles and strategies applicable to textbook-free course design, materials development, and task-based pedagogical decision-making, while acknowledging contextual variations in institutional structures, learner demographics, and disciplinary focus. Method Research Design and the Participants The current endeavour deployed a design-oriented qualitative research approach, a methodology particularly suited for investigating pedagogical challenges and curriculum opportunities within authentic educational settings (Verschuren & Hartog, 2. Design-oriented research emphasizes the iterative cycles of planning, implementation, observation, and reflection, allowing researchers to systematically examine the development and enactment of instructional interventions while generating contextually grounded insights. The approach is particularly appropriate for this study as it facilitates the exploration of dual dynamics: the constraints imposed by textbook-free ESP course design and the opportunities for curriculum innovation, pedagogical creativity, and learnercentered instruction. The current endeavour may investigate and document the observable processes, practices, rationale, decision-making, and reflective considerations, underpinning course design and delivery (Almquist & Lupton, 2. The participants were selected using purposive sampling to ensure that they could provide rich, relevant, and context-specific insights into the ESP course under study. The sample included 38 undergraduate students enrolled in the Business Administration program and two ESP instructors responsible for course design and delivery. Purposive sampling was chosen to ensure that participants were actively engaged in the textbook-free ESP environment and could provide in-depth perspectives on both pedagogical and curricular aspects. The students represented a range of English proficiency levels, academic performance histories, and prior exposure to business communication tasks, providing a heterogeneous sample that enhanced the comprehensiveness of the data. The instructors were selected based on their experience in ESP instruction, involvement in course development, and willingness to participate in iterative reflections throughout the semester.

Percentage (%) Stages of the Research Design Three interconnected stages were directed in this study, reflecting the iterative design-oriented qualitative framework: course planning, materials development, and instructional enactment. Each stage was conceptualized, executed, and analyzed to capture both the challenges and opportunities inherent in textbook-free ESP course design. Stage 1: Course Planning The first stage focused on establishing the course framework, objectives, learning outcomes, and assessment strategies. This involved a comprehensive needs analysis, drawing on both the instructorsAo professional judgment and preliminary student feedback regarding English proficiency, business communication requirements, and prior exposure to ESP content. During this stage, instructors systematically mapped out the course syllabus, sequencing content to align with key business competencies, such as professional correspondence, presentations, report writing, and negotiation communication. The planning process also included establishing assessment rubrics, learning goals, and criteria for task-based activities to ensure alignment between learning outcomes and instructional interventions. Observational notes and reflective logs were maintained to document the decision-making process and any anticipated challenges, such as balancing task complexity with student proficiency and ensuring content relevance without relying on preexisting textbook structures. This stage provided foundational insights into pedagogical challenges, particularly regarding the need to integrate authentic business materials and create coherent sequences of learning tasks in a textbookfree environment. Stage 2: Materials Development The second stage emphasized the creation, adaptation, and curation of instructional resources tailored to the identified course objectives. This stage was characterized by the selection of authentic business materials, including company reports, business emails, case studies, and professional Materials were evaluated for their alignment with both task-based learning principles and the specific communicative competencies targeted in the ESP curriculum. Instructors documented their process of material selection, adaptation, and scaffolding, reflecting on the alignment of each activity with learning outcomes and potential challenges in implementation. Particular attention was given to ensuring that tasks provided sufficient scaffolding for students at varying proficiency levels while remaining relevant to professional business practices. This stage also highlighted opportunities for curriculum innovation, as instructors could tailor activities to contextual needs, integrate real-time feedback mechanisms, and experiment with task sequencing. Teaching reflections, meeting notes, and design artifacts generated during this stage were systematically collected for analysis, providing detailed evidence of both instructional constraints and emerging curricular opportunities. Stage 3: Instructional Enactment The third stage involved the implementation of the ESP course over one academic semester, during which materials were delivered, tasks enacted, and student engagement observed. Instructional enactment included classroom observations, instructor reflective journals, and ongoing formative assessments, allowing for iterative adjustments to instructional strategies and task design.

Hilman Fikri documented in this stage included managing student engagement across varying proficiency levels, ensuring consistency in task difficulty, and addressing unanticipated gaps in content or task clarity. Conversely, opportunities emerged in the form of increased responsiveness to learner needs, enhanced contextualization of tasks, and greater autonomy for instructors in adapting activities. Student feedback instruments, including reflective questionnaires and focus discussions, provided complementary perspectives on the effectiveness of instructional strategies and the perceived value of the textbook-free curriculum. This stage was crucial in illustrating the interplay between pedagogical decision-making and curriculum opportunities, demonstrating how iterative reflection and adaptive instruction contributed to achieving learning coherence and relevance. Instruments Data were collected through multiple complementary instruments to ensure triangulation and depth of insight, reflecting the design-oriented qualitative framework (Verschuren & Hartog, 2. Instructional Design Artifacts: Course syllabi, lesson plans, task sequences, and assessment rubrics were analyzed to understand the planning rationale, alignment with ESP competencies, and integration of authentic materials. These artifacts provided tangible evidence of both pedagogical challenges and curriculum opportunities. Teaching Reflections: Instructors maintained reflective journals throughout the semester, documenting decisions, observed student responses, perceived difficulties, and adaptations made to materials or tasks. These reflections were critical for understanding the iterative processes of course design and implementation. Learner Feedback Instruments: Structured reflective questionnaires and short written reflections were used to capture studentsAo perceptions of task relevance, engagement, and learning outcomes. Feedback focused on studentsAo experiences navigating tasks without prescribed textbooks and their perceptions of curriculum coherence and utility. Focused Instructor Interviews: Semi-structured interviews with the two instructors provided in-depth insights into course planning, instructional enactment, challenges encountered, and opportunities leveraged. Interviews also explored instructorsAo rationale for materials selection, task design, and adaptations during the course. Observational Notes: Classroom observations captured student engagement, participation, and interaction patterns, as well as real-time implementation of instructional strategies. Observational data complemented reflections and feedback instruments, providing a holistic view of instructional processes. Data Collection Procedures A comprehensive multi-method approach was designed to capture to capture the intricate dynamics of pedagogical challenges and curriculum opportunities in a textbook-free ESP for Business course, following the principles of design-oriented qualitative research, which emphasize iterative cycles of planning, implementation, and reflective refinement (Almquist & Lupton, 2. The data collection process began with the compilation and analysis of instructional design artifacts, including course syllabi, lesson plans, task sequences, and assessment rubrics, which documented curriculum decisions, task sequencing, and intended learning outcomes, allowing a systematic evaluation of alignment with targeted business English competencies. Instructors maintained detailed reflective journals throughout the semester, recording observations on student engagement, instructional effectiveness, emergent challenges, and adaptive strategies employed in real time, providing insight into the iterative decision-making processes that underpinned course enactment. Complementary learner feedback instruments, such as structured reflective questionnaires and open-ended prompts, were administered at multiple intervals to capture studentsAo perspectives on task relevance, materials At-Ta'lim: Jurnal Pendidikan.

Hilman Fikri effectiveness, and learning coherence, highlighting the experiential dimensions of navigating a textbook-free environment. Focused semi-structured interviews with instructors were conducted before, mid-, and post-semester, probing instructional planning, materials development, task sequencing, and assessment practices, while classroom observations documented participation, interaction patterns, and real-time instructional adjustments. Data Analysis Data were analyzed using thematic qualitative analysis, an approach suitable for identifying patterns, relationships, and emergent themes within complex educational contexts (Braun & Clarke. The process began with thorough familiarization, involving repeated readings of transcripts, reflective journals, observational notes, and instructional artifacts to identify initial patterns and recurring issues. A coding framework was then developed, combining deductive codes based on study variables, including pedagogical challenges, curriculum opportunities, course design, instructional planning, task adaptation, assessment alignment, materials selection, learner engagement, and reflective decision-making, with inductive codes emerging from unanticipated phenomena such as student strategies and instructor improvisation. A systematic multi-stage coding procedure was applied, beginning with open coding to generate initial labels, followed by axial coding to identify relationships between codes, and selective coding to synthesize core themes addressing the research Triangulation across multiple data sources, independent researcher review, member checking, analytical memos, and structured reflexivity ensured trustworthiness, mitigated bias, and supported rigorous, credible, and contextually grounded thematic interpretations (Braun & Clarke. Ethical Considerations Ethical considerations were strictly observed throughout the study to ensure participant protection and research integrity. The study gained an ethical approval from Universitas Cipta Wacana review board, and all participants provided informed consent. Confidentiality and anonymity were maintained through secure data storage, de-identification of participant information, and restricted access to research data. Students were assured that participation would not affect academic evaluation, and instructors could provide candid reflections without repercussions. Bias mitigation strategies included reflexive journaling, peer debriefing, data triangulation, and member checking to ensure credible, trustworthy, and ethically responsible findings. Results and Discussion Pedagogical Challenges in the Design and Delivery of a Textbook-Free ESP for Business Course To address RQ1, the study explored the pedagogical challenges in designing and delivering a textbook-free ESP for Business course using a design-oriented qualitative approach. Iterative processes of course planning, materials development, and instructional enactment were examined, with multiple data sources, including instructional artifacts, teaching reflections, learner feedback, and instructor interviews, triangulated to provide a nuanced understanding of recurring challenges, emergent issues, and contextual constraints. Instructional Design Artifacts The analysis of instructional design artifacts, including course syllabi, lesson plans, assessment rubrics, and task sequences, revealed challenges primarily related to the alignment of learning outcomes with task-based activities, the selection and sequencing of authentic materials, and the management of instructional coherence across the semester. In a textbook-free context, instructors needed to ensure that each activity was pedagogically sound, appropriately scaffolded, and aligned At-Ta'lim: Jurnal Pendidikan. ISSN 2460-5360 . | 2548-4419 .

Discussion The findings of this study illuminate the complex landscape of designing and delivering a textbook-free ESP for Business course, revealing multifaceted pedagogical challenges and curriculum opportunities that extend existing knowledge while providing nuanced insights for both theory and The pedagogical challenges identified demonstrate that alignment of tasks with learning outcomes is a central concern, reflecting the intricate interplay between curriculum intentions and realworld application. This requirement for precise alignment underscores that ESP course design necessitates meticulous planning to ensure that tasks do not merely replicate textbook exercises but authentically address professional communication competencies. Previous studies have highlighted the importance of outcome-oriented course design in ESP contexts (Hyland & Jiang, 2021. Iswati & Triastuti, 2021. Marcu, 2. , yet the present study advances this understanding by showing that textbook-free settings amplify the need for iterative alignment, continuous reflection, and adaptive modifications throughout the course. The challenges encountered in materials selection further extend At-Ta'lim: Jurnal Pendidikan. ISSN 2460-5360 . | 2548-4419 . At-Ta'lim: Jurnal Pendidikan, 12. , 2026, 137-156 Abd. Syakur. Yulianto Sabat. Ika Rahmania. Lailatul Musyarofa. Moh. Hilman Fikri prior findings on authentic resource integration (Albers et al. , 2020. Pramila et al. , 2. by demonstrating that instructors must negotiate the dual imperatives of authenticity and accessibility. Authentic materials enrich learning by situating tasks in realistic professional contexts, but without the scaffolding provided by a textbook, the instructional burden increases, necessitating careful task sequencing and the integration of supplementary supports to bridge learner comprehension gaps. This dynamic emphasizes the critical role of instructor agency, reflective practice, and adaptive expertise in managing complexity and maintaining curriculum coherence. Learner heterogeneity emerged as another significant dimension influencing pedagogical decision-making. The study illustrates that students with diverse English proficiency levels, prior experiences with business communication, and variable self-directed learning capacities demand differentiated instructional strategies. These finding complements research highlighting the challenges of addressing diverse learner profiles in ESP classrooms (Chan, 2019, 2. while extending it by evidencing that a textbook-free environment magnifies these differences, compelling instructors to develop real-time adaptive strategies. These strategies include flexible task designs, tiered scaffolding, and formative feedback mechanisms, which collectively sustain learner engagement and facilitate meaningful skill development. Furthermore, the iterative observation and reflection embedded in design-oriented qualitative research enabled instructors to continuously recalibrate instructional practices, thereby creating a responsive learning environment that supports both individual progression and collective coherence. The necessity for ongoing reflective practice illustrates that ESP instruction in resource-limited or textbook-free settings is inherently dynamic, requiring a continual negotiation between curriculum intentions, task complexity, and learner readiness (KosoviN, 2025. Nguyen et al. Yang, 2. The study also highlights that pedagogical challenges can generate complementary curriculum opportunities, demonstrating the productive tension inherent in textbook-free ESP design. Flexibility in task design allowed instructors to tailor activities to professional relevance and learner needs, fostering deeper engagement and promoting the development of critical workplace competencies. This finding aligns with literature emphasizing task-based learning and the benefits of authentic, contextually situated instruction (Chan, 2024. Pramila et al. , 2. , while extending understanding by showing that iterative design processes in the absence of a textbook provide enhanced opportunities for curricular innovation, including the integration of multimedia resources, cross-disciplinary skills, and real-world problem-solving scenarios. The study reveals that the constraints associated with textbook-free environments, such as the absence of standardized task sequences or pre-structured scaffolding, can be leveraged as opportunities to cultivate learner autonomy, reflective thinking, and adaptive expertise. Such opportunities reflect a shift from conventional content-driven curricula toward a process-oriented and learner-centered paradigm, emphasizing that ESP education benefits from flexibility, contextual responsiveness, and iterative refinement (Cheng, 2. Moreover, the integration of authentic materials in this study highlights the potential for curriculum to be both highly contextualized and strategically scaffolded. While prior research acknowledges the value of authentic resources in ESP (Dou et al. , 2023. Harwood, 2. , the present study demonstrates that these materials, when combined with iterative planning and reflective adjustments, can serve as a vehicle for simultaneously addressing pedagogical challenges and fostering curriculum innovation. The dynamic adjustment of task complexity, sequencing, and scaffolding in response to learner progress exemplifies how curriculum opportunities emerge directly from challenges, producing a reciprocal relationship between constraint and innovation. This interplay suggests that textbook-free ESP design is not merely a compensatory approach but a strategic modality for developing curricula that are contextually meaningful, flexible, and learner-responsive (Han et al. At-Ta'lim: Jurnal Pendidikan. ISSN 2460-5360 . | 2548-4419 . At-Ta'lim: Jurnal Pendidikan, 12. , 2026, 137-156 Abd. Syakur. Yulianto Sabat. Ika Rahmania. Lailatul Musyarofa. Moh. Hilman Fikri Another salient contribution of the study is the illumination of how iterative reflection and adaptive decision-making contribute to the emergence of curriculum coherence. The design-oriented qualitative approach allowed instructors to continually assess task alignment, materials appropriateness, and learner engagement, thereby maintaining cohesion in a setting without a predefined textbook structure. This finding builds on the theoretical foundations of design-oriented research (Ellederovy, 2022. Pramila et al. , 2. and underscores the importance of reflective practice not only as a mechanism for problem-solving but as a generator of pedagogical insights and curriculum opportunities. In particular, the ability to adapt tasks in real time, respond to learner feedback, and integrate emerging business contexts illustrates how curriculum design can be simultaneously structured and flexible, promoting both standardization in intended outcomes and responsiveness to situational contingencies. The present study also advances understanding by emphasizing the interplay between challenges and professional skill development. By confronting difficulties related to task alignment, materials curation, and learner heterogeneity, instructors were able to strategically craft learning experiences that enhance business communication competencies, critical thinking, and problemsolving abilities. This extends previous claims on ESP curriculum design (Hyland, 2022. Hyland & Jiang, 2. by evidencing that textbook-free approaches allow for a more authentic simulation of workplace demands, fostering practical skills in addition to linguistic competence. The iterative cycles of design, reflection, and adaptation not only mitigated pedagogical difficulties but also generated new curriculum opportunities, including interdisciplinary integration, technology-enhanced learning, and increased learner autonomy. Consequently, the study illustrates that challenges in textbook-free ESP course design are not merely obstacles but catalysts for innovation and professional skill cultivation. Overall, the findings reveal that the textbook-free approach to ESP instruction embodies both complexity and potential. Pedagogical challenges such as task alignment, materials selection, learner heterogeneity, and assessment calibration are intertwined with curriculum opportunities related to authentic task design, learner-centered engagement, reflective practice, and adaptive curriculum By situating these findings within the broader literature on ESP, task-based learning, and design-oriented research, the study demonstrates that textbook-free environments necessitate a high degree of instructor agency and reflective practice but simultaneously offer enhanced potential for curriculum responsiveness, professional relevance, and learner empowerment. This duality underscores the value of a design-oriented approach for navigating the tensions between constraints and opportunities in ESP course development. The study provides a comprehensive framework for understanding how pedagogical challenges can be transformed into curriculum opportunities, offering insights that are transferable to similar higher education contexts seeking to implement flexible, contextually responsive, and learner-centered ESP courses. Conclusion The findings of this study provide a comprehensive understanding of the dual nature of textbook-free ESP course design, revealing both challenges and opportunities that shape instructional practices and curriculum development. On one hand, pedagogical challenges such as aligning tasks with learning outcomes, selecting and adapting authentic materials, managing task complexity, and addressing learner heterogeneity required significant instructor effort, reflective practice, and iterative adjustments, highlighting the dynamic and labor-intensive nature of textbook-free pedagogy. On the other hand, these constraints generated substantial curriculum opportunities, including enhanced flexibility in task design, integration of real-world business contexts, promotion of learner autonomy, iterative curriculum refinement, and development of critical professional competencies. The study has implications for both theory and practice, demonstrating that design-oriented approaches enable instructors to transform challenges into opportunities, fostering learner-centered and contextually At-Ta'lim: Jurnal Pendidikan.
