This research was qualitative descriptive research with content analysis. The analysis was carried out on five books that are widely used in the school. Reports and activities were analyzed using content analysis through an assessment rubric based on Social Cognitive Career Theory (SCCT) which are awareness, relevance, engagement and self-efficacy. The analysis showed that the STEM career content in science junior high school textbooks were still lacking. The books were not sufficient in presenting content about careers in the STEM field. These results indicated that none of the five textbooks had fulfilled the four aspects of STEM career. The aspect most commonly found in the textbooks was self-efficacy, and the most observed STEM career content was found in the earliest chapter, which is Nature of Science. These findings hig...

This study aims to improve students' critical thinking skills using Project-Based Learning (PjBL) model with a STEM approach (STEM-PjBL) on optics topics. This study used a quantitative approach and one group pretest-posttest design. The sampling technique used cluster random sampling and the sample used consisted of 35 students of a class in a public high school at Samarinda. Data collection uses test techniques with 6 questions in the form of essays. The results of this study showed that using STEM-PjBL on optics topics can significantly improve students' critical thinking skills with sig values. (2-tailed) in paired T-test 0.000 and N-Gain 0.74, which is included in the high criteria. After learning, 34% of students are in the highly critical category and 66% in the critical category. The PjBL model with the STEM approach can be used to train the critical thinking skills of ...

This research uses research and development design (Research and Development, R &D). The model used in this study is a modification of the 4-D model from four stages to three stages 3-D including the define, design, and development stages proposed by Thiagarajan. RPP, LKPD, handouts, and assessment instrument validation sheets are used to measure the validity of learning devices. Student response questionnaires and observation sheets for the implementation of learning activities are used to measure the practicality of learning devices. Pretest-posttest, N-gain, and effect size tests are used to measure the effectiveness of learning devices. The results showed that learning devices were declared very valid with a percentage of 90%, learning devices were declared practical with a percentage of 83%, effective learning devices to i...
