Abstract

21st century learning requires students to develop problem-solving skills with creative ideas. Identifying objects, formulating problems, exploring creative ideas and choosing the best solution are important skills in solving creative problems. STEM-PjBL learning integrated with the local potential of sand crackers is one alternative to improve their skills. The purpose of writing is to developing a STEM-PjBL model science e-books on temperature and heat material to improve students creative problem solving skills of junior high school students. The development model used is 4-D model, with stages including define, design, develop, and disseminate. The research subjects were students of class VIII MTsN 4 Kediri. Data collection was done through tests and non-tests (questionnaires, observations, interviews). The instruments used were product feasibility, validation sheet from material experts and media experts, instrument validation sheet, and practicality questionnaire. The results of the material validation and media validation are very good category with scores of 207 and 329 respectively. The percentage score of practicality questionnaire assessment is 93.9% and the score of the readability questionnaire assessment is 92.7%. The N-gain value of 0.46. It can be concluded that the STEM-PjBL science ebook developed effectively increases students' creative problem solving skill

Abstract

The low critical thinking ability of Indonesian students is known based on the acquisition of PISA and TIMMS assessments with positions in the lower middle rankings. The lack of teaching materials that facilitate the improvement of critical thinking skills is one of the contributing factors. The purpose of this research and development is to produce a substance stress module to improve the critical thinking skills of junior high school students using model discoverylearning. The development model used is 4-D, with stages including define(definition), design(planning), develop(development), and disseminate(spread). Data collection was carried out through a literature review, validation assessment, and e-module practicality response questionnaires. Data collection was carried out through instruments in the form of validation assessment sheets by practitioners and student practicality response questionnaire sheets. Practitioners assess the validity of teaching materials, while their practicality is assessed by students. The results of the material validation were 89.2% (very valid), the media validation was 90% (very valid), the student practicality questionnaire was 76.2% (practical), and the N-gain score was 0.46. These results indicate that the science modules developed are valid and practical for use in science learning
