Profile of Problem-based Learning (PBL) Model Assisted by PhET to Improve Critical Thinking Skills of High School Students in Dynamic Electrical Materials

This study discusses the implementation of problem-based learning (PBL) assisted by physics education technology (PhET) as a virtual laboratory to improve the critical thinking skills of high school students on dynamic electrical materials. The purposes of this research were to obtain the profile of students' critical thinking skills and the implementation of PBL assisted by PhET in senior high schools. This research method was a preliminary study with a qualitative descriptive analysis, written tests, student response questionnaires, and teacher interviews. The finding of students' critical thinking skills was categorized into three levels (low, moderate, and high). There are seventeen students in the low category, fifty-three students in the moderate category, and thirty students in the high category. The conclusion of this study revealed that students' critical thinking skills at the senior public school Surabaya were in the moderate category, and training questions were needed to improve students' critical thinking skills

Comparison of Basic Science Process Skills for Students on Electrical Materials with the Rasch Model Analysis

Prospective teacher students must have good science process skills to create learning that focuses on science process skills-based learning. This study aims to describe the comparison of the basic science process skills of prospective elementary school teachers in electric subjects. This research is descriptive. The sample of this study was 184 students consisting of 104 students in the 4th semester and 80 students in the 6th semester. The data collection technique was using a test that consists of 25 questions about basic science process skills. Data analysis using the Wright Person Map in Rasch Model. Based on the results, the researcher obtained information that most prospective elementary teachers' science process skills were classified as moderate. In addition, the results were obtained that the science process skills of 6th-semester students were better than the 4th semester. This research also found that the science process skill of female students was better than male students.
