Development of kehatimu digital worksheet pjbl STREAM to improve science literacy and creative thinking skills

Using the environment as a learning environment has great potential to be developed. Biodiversity in Indonesia, including the slopes of Mount Muria, can be used as a source of learning for student participants. Previous studies' results stated that students' Science Literacy and creative thinking skills on Mount Muria's slopes need improvement. There needs to be learning that can trigger and train students' Science Literacy and creative thinking skills to improve these abilities. The science, technology, religious, engineering, art, and mathematics (STREAM) approach can present more meaningful learning, especially if integrated with project-based learning models and IT. This study aims to develop a digital worksheet titled Kehatimu (Keanekaragaman Hayati Muria) with the PjBL STREAM model to improve students' science literacy and creative thinking skills. The method used is R&D with the define, design, development, and disseminate (4D) model. Data collection involved both test instruments (science literacy and creative thinking assessments) and non-test instruments (feasibility and readability questionnaires, as well as attitudinal scales toward science literacy and garden design creativity assessment rubric). The study involved 135 students from three schools located on the slopes of Mount Muria, divided into experimental and control groups. Data analysis using SPSS included the N-Gain and independent t-tests. Expert validation yielded a feasibility score of 0.90 (categorized as very feasible), while readability analysis scored 4.3 (high readability). Results demonstrated that the digital worksheet is interactive, user-friendly, relevant, and contextually grounded. Furthermore, significant improvements (p < 0.05) were observed in both scientific literacy and creative thinking scores, with averages exceeding the Learning Mastery Level (LML) threshold of 70. In conclusion, the Kehatimu digital worksheet can improve students' scientific literacy and creative thinking related to Mount Muria’s biodiversity.
