<![CDATA[Contextual science worksheets are needed to help students connect temperature and heat concepts with real-life socio-environmental issues. This study aimed to develop and assess the feasibility of a contextual STEM-based student worksheet integrating socioscientific issues (SSI) for temperature and heat learning. This research employed a Research and Development design using the ADDIE model, limited to the analysis, design, and development stages. Data were collected using expert validation sheets and student response questionnaires. The worksheet was validated by three media experts and three material experts and was revised based on their suggestions. A limited trial involving 30 junior high school students was conducted to examine student responses. Media validation obtained an average score of 86%, while material validation obtained an average score of 87%. Student responses reached 87%, indicating a very interesting category. These findings show that the worksheet is visually appropriate, conceptually relevant, linguistically understandable, and attractive for contextual science learning. The developed worksheet is feasible for supporting temperature and heat learning at the junior high school level. Further research is needed to examine its effectiveness on students’ learning outcomes and problem-solving skills.]]>
