Arabic dan Educational of Natural Science INTRODUCTION The development of teaching materials is a crucial aspect of enhancing the quality of education. The need for such development often arises from curriculum evolution, advancements in science and technology, and changes in global As society and labor market needs evolve, it is essential to ensure that instructional materials remain relevant and aligned with current developments. Mismatches between teaching materials and student needs, a lack of resources, and the demand to create a stimulating learning environment for creativity and deep understanding form the foundation for developing teaching materials (Rivasintha Marjito & Hidayat, 2. According to Dick and Carey "Instructional material development is a systematic process to ensure that the material delivered achieves the established learning objectives (Magdalena et al. , 2. states, "Instructional design is an effort Volume 13 . November 2024, page 483-498 Copyright A2024. ISSN: 2252-7818 E-ISSN: 2502-3543 Available online: https://journal. id/index. php/exposure Exposure: Jurnal Pendidikan Bahasa Inggris Exposure Journal 484 to design effective and efficient learning materials that meet the needs of learners. "Evaluation is a crucial step in instructional material development because it allows us to determine how effective the material is in achieving learning objectives (Calhoun et al. , n. )Therefore, the development of teaching materials often includes efforts to improve educational quality, respond to changes in learning paradigms, and ensure that every student can access high-quality and relevant education (Wulandari & Kunci, 2. The development of teaching materials is also closely related to the concept of inclusive education, which emphasizes equal learning opportunities for all students, including those with different learning styles or special educational needs. This background highlights the importance of creating materials that can be adapted to varying levels of understanding, learning speeds, and learning styles. The integration of technology in learning also represents a significant factor, as technological advancements offer potential to enhance accessibility, engagement, and learning effectiveness (Therasa, n. The importance of active learning and student engagement has become a focus in contemporary education. Consequently, developing teaching materials that facilitate these methods is crucial. Diversity in student needs means that each student has different learning styles and needs. Developing teaching materials can help create content that accommodates these diverse needs and learning styles. Addressing specific learning challenges, such as varying levels of understanding or learning speeds, can also be part of the development process (Esteban-Yago et al. This research is expected to produce an output in the form of the development of teaching materials for "English and Arabic for Educational of Natural Science" for students at the State College Islamic of Mandailing Natal. MATERIALS AND METHOD Materials Educators and educational experts have introduced various terms related to teaching materials. Fundamentally, teaching materials can be defined as learning resources that are comprehensively and systematically organized based on learning principles applied by teachers and students during the teaching and learning process (Al-Ta et al. , 2. The systematic nature of teaching materials reflects an orderly Volume 13 . November 2024, page 483-498 Copyright A2024. ISSN: 2252-7818 E-ISSN: 2502-3543 Available online: https://journal. id/index. php/exposure Exposure: Jurnal Pendidikan Bahasa Inggris Exposure Journal 485 arrangement, facilitating the learning process for students. Additionally, teaching materials possess unique and specific characteristics. Uniqueness refers to their particular use for specific purposes and contexts of learning, while specificity indicates that the content is designed to achieve certain competencies aligned with the established learning objectives (Kusuma & Apriyanto, 2. According to Belawati, teaching materials can be defined as lesson resources that are arranged comprehensively and systematically according to the learning concepts applied by teachers and students during the educational process. The success of teaching materials lies in their systematic nature, which means they are organized in a structured manner to facilitate the learning process for students. Furthermore, teaching materials have distinctive and specific characteristics. Uniqueness in this context refers to their use for specific goals and particular learning situations. Moreover, the specific nature of teaching materials indicates that their content is designed to achieve specific competencies aligned with the set learning objectives (Wulandari & Kunci, 2. Teaching materials relate to various types of content used to support educators in conducting classroom activities. These materials can include both written and non-written resources, as noted by Pastowo On the other hand. Widodo defines teaching materials as a set of resources encompassing learning content, approaches, parameters, and evaluation techniques that are structured and engaging. All these elements aim to achieve the desired learning outcomes, namely acquiring competencies and sub-competencies with all their complexities (Setyowati dkk, (Fitriah, 2. states that teaching materials involve various types of resources used to support educators during the learning process. These materials can be either written or non-written. The use of teaching materials allows students to systematically and sequentially master a competency or basic competence, thereby ensuring that their skills comprehensively cover the entire competency in a thorough and integrated manner. Emphasizes the essential function of teaching materials in the educational These materials play a key role by offering clear directions for structuring learning activities, providing comprehensive content and resources for each task, serving as a link between teachers and students, being easily accessible to help Volume 13 .

According to Dick and Carey . , teaching materials are essential components in learning that must be systematically designed to ensure that the material delivered achieves the established learning goals. Heinich et al. add that appropriate use of teaching materials can enhance learning effectiveness and help learners achieve learning objectives. Therefore, the development of teaching materials must be carried out carefully and based on a thorough analysis of learning needs (Rukmi Octaviana et al. , n. Overall, teaching materials play a crucial role in the learning process. Their functions include providing clear guidance for learners in conducting learning activities, presenting comprehensive materials and equipment for each activity, serving as a bridge between educators and students, being usable independently by learners to achieve desired goals, and being applicable in improvement programs. Thus, the importance of teaching materials in supporting learning effectiveness and achieving specific learning objectives is evident (Phd et al. , 2. English language learning is a stage where individuals acquire communication skills in English. The main goal of English language learning is to enable students to listen, speak, read, and write in this language. This learning process involves understanding grammar concepts, vocabulary, and the use of English in various communicative contexts (Alek, 2. English language learning is a complex and dynamic process involving various linguistic and non-linguistic aspects to develop learners' language In English language learning, students are taught basic language skills including listening, speaking, reading, and writing. Each of these skills is interrelated and crucial for achieving effective communication in English. This learning process aims not only to teach grammar and vocabulary but also to develop critical thinking skills and a broader cultural understanding (Sharifian, 2. Arabic language learning is an educational process aimed at teaching learners to communicate in Arabic, both orally and in writing. This process includes mastering four main skills: listening, speaking, reading, and writing, as well as understanding grammar, vocabulary, and pronunciation. In addition to linguistic aspects. Arabic language learning often involves introducing the culture and social Volume 13 . November 2024, page 483-498 Copyright A2024. ISSN: 2252-7818 E-ISSN: 2502-3543 Available online: https://journal. id/index. php/exposure Exposure: Jurnal Pendidikan Bahasa Inggris Exposure Journal 487 context in which the language is used. This is important for understanding the use of the language in a broader and deeper context (Muhammady, n. According to Ahmad . Arabic language learning aims not only to master the language technically but also to understand the cultural and social values embedded within it. This learning strives to create effective communication skills and mutual respect for cultures by providing knowledge about history, customs, and relevant social norms. This approach allows learners to better understand and appreciate Arabic as part of a rich cultural heritage (Setyawan, 2. English for Specific Purposes (ESP) refers to teaching English tailored to the specific needs of learners in various professional, academic, or technical fields. Unlike general English courses that focus on overall language proficiency. ESP targets language skills and vocabulary relevant to specific contexts such as business, medicine, engineering, or law. The main goal of ESP is to equip learners with the language skills necessary to function effectively in their areas of interest. This approach emphasizes practical language use over theoretical knowledge, ensuring that learners acquire communication skills that can be directly applied in their professional or academic environments (Hyland, 2. According to Hutchinson and Waters ESP is driven by learners' needs and designed to be relevant to their specific requirements. They argue that ESP courses should be tailored to meet the linguistic demands of particular fields or professions, thereby enhancing the relevance and effectiveness of language teaching. For example, a Business English course may focus on language used in meetings, negotiations, and presentations, while a Medical English course might concentrate on medical terminology, patient communication, and clinical documentation (Anqi Dou, 2. Similarly. Arabic for Specific Purposes (ASP) refers to teaching Arabic with a focus on specific professional or academic needs. This approach is increasingly important in contexts where Arabic is used in specialized fields such as diplomacy, international relations, trade, or religious studies. ASP programs are designed to meet the specific linguistic needs of learners who require proficiency in Arabic for particular purposes, such as understanding legal documents, engaging in diplomatic negotiations, or studying classical Islamic texts (Fatoni, 2.

Research and development involve investigative activities aimed at acquiring new knowledge or creating new and improved products, services, or processes. This encompasses a range of activities, from basic research aimed at expanding scientific understanding to applied research focused on specific practical objectives. According to Emily (Hemilia et al. , 2. R&D plays a crucial role in developing more effective curricula and teaching methods. Innovations in education can create more meaningful learning experiences for The aim of this research is to develop a textbook titled "English and Arabic for Educational of Natural Science" for the Educational of Natural Science at the State College Islamic of Mandailing Natal. The results of this research will be utilized by English and Arabic lecturers teaching in this program. Borg and Gall state that R&D involves "a series of steps undertaken with the goal of developing a product, testing the product, conducting field trials, and making adjustments to the product after the field-testing phase (Fitrina Defi & Pratami, n.
