Abstract Critical thinking skills (CTS) are essential competencies in science education for preparing students to respond to complex socioscientific challenges in the 21st century. Nevertheless, empirical evidence and classroom practices indicate that Indonesian studentsAo CTS remain at a low level, particularly in biotechnology learning, which often requires higher-order This condition is exacerbated by the dominant use of textbook-centered instruction and the limited availability of digital teaching materials that systematically integrate real-world socioscientific issues (SSI). Therefore, the development of innovative, context-based instructional materials is urgently needed. This study aimed to examine the validity, practicality, and effectiveness of a science e-module integrating the Problem Based Learning (PBL) model and SSI to enhance studentsAo CTS in A Research and Development approach using the ADDIE model was employed, involving 32 ninth-grade students at a Public Junior High School 11 Magelang. Data were collected through expert validation sheets, student response questionnaires, and CTS pretestAeposttest instruments. The results showed that the emodule was valid (AikenAos V = 0. , practical . %), and effective in improving studentsAo CTS, as indicated by a significant Wilcoxon Signed-Rank Test result . = 0. with a moderate N-Gain of 0. These findings suggest that integrating PBL and SSI in a digital emodule effectively supports the development of studentsAo critical thinking skills in science learning. Keywords: science e-module.

This skill plays a crucial role in enabling students to analyze information, evaluate evidence, and make rational decisions regarding increasingly complex scientific and social issues. However. Indonesian studentsAo mastery of critical thinking skills remains relatively low. The 2022 Programme for International Student Assessment (PISA) results indicate that the higher-order thinking skills of 15-year-old students are at levels 2 to 3, which are still below international standards . These findings are reinforced by national studies reporting low levels of critical thinking achievement among junior high school students, including in biotechnology topics . A similar condition was also identified in science learning at SMP Negeri 11 Magelang City. The results of preliminary observations indicate that studentsAo critical thinking skill indicators, particularly in the aspects of interpretation, analysis, and selfregulation, have not developed percentages of 0%, 7%, and 38%. This finding suggests that the ongoing learning process has not fully facilitated students to think critically and reflectively. Therefore, innovative and sustainable efforts are instruction that can systematically train studentsAo critical thinking skills. The use of technology in science education has been proven to enhance the quality of the learning process and support the development of studentsAo critical thinking skills . One form of instructional material with strong potential for this purpose is the emodule, as it allows content to be delivered in a self-directed, interactive, and flexible manner . However, in practice, many schools in Indonesia still rely heavily on textbooks as the primary learning resource, including at SMP Negeri 11 Magelang City. This reliance limits studentsAo independent inadequately supports contextual learning and instruction oriented toward the development of higherorder thinking skills . The selection of instructional materials must be accompanied by the implementation of an appropriate learning model. The Problem-Based Learning (PBL) model has been widely reported to be effective in enhancing critical thinking skills because it positions students at the center of learning and uses authentic problems as triggers for the thinking process . Nevertheless, the effectiveness of PBL is highly dependent on the quality of the problem context and the learning media employed. PBL that is not supported by contextual and relevant instructional materials may lose its potential to foster deep critical thinking In the context of science learning, particularly biotechnology, the problems employed in PBL should ideally be linked to socioscientific A socioscientific issueAebased approach enables students to connect scientific concepts with social, ethical, and environmental realities, thereby promoting evidence-based decisionmaking and critical reasoning . Socioscientific issues frequently arise in biotechnology topics, such as Handy Ichsa Janand. Agista Sintia D.

Learning Objectives (TP), and science understanding elements in accordance with the Merdeka Curriculum. analyzing the PBL model syntax to be integrated into the e-module activity flow. analyzing the content of socioscientific issues selected based on criteria of educational value in local, national, and global contexts. Evaluation at this stage was conducted through the distribution of a needs assessment questionnaire to 32 students and one subject teacher, as well as an initial diagnostic analysis of critical thinking skills using six multiple-choice questions. Design Stage The design stage was carried out by developing an initial framework for the e-module, which included biotechnology content. PBL syntax, and socioscientific issue components. Additionally, the e-module format was designed, covering layout, the use of QR codes, and supporting hyperlinks. At this stage, research instruments were also prepared, including an expert validation sheet, pretestAeposttest questions for critical thinking skills, and a practicality questionnaire. The initial e-module design was then consulted with the supervising lecturer to obtain feedback before proceeding to the development stage, serving simultaneously as an evaluation of the design phase. Development Stage The development stage involved the initial production of the e-module based on the final framework from the design stage. Content was prepared using Microsoft Word, while the visual design was developed using Canva. The initial e-module prototype was then reviewed internally with the supervising lecturer as a form of formative evaluation. After revisions were made, the emodule and research instruments were validated by experts. Content validity was assessed based on material feasibility, presentation, language, and graphics using a validation sheet, and then analyzed using AikenAos V index with the following formula: yuyc ycO= ycu . ca Oe . ycI = yc Oe yco0 where s is the total score from the validators, n is the number of validators, and c is the scoring range. An item is considered valid if V Ou 0. This approach is used to ensure that the level of agreement among evaluators does not occur by chance . Feedback from the validators was used as the basis for revising the e-module before proceeding to the limited trial phase and also served as an evaluation effort in the development stage. Implementation Stage The e-module that had been declared valid was subsequently implemented in a limited trial with 32 students of Class IX A at SMP Negeri 11 Magelang City. The practicality of using the e-module was analyzed using a student response questionnaire with a five-point Likert scale . The practicality score was calculated using the following formula: ycIycaycuycyce P = ycAycaycuycnycoycyco ycycaycuycyce x 100% Handy Ichsa Janand. Agista Sintia D.
