Abstract

This study aims to develop instruments measuring the ability to solve physics problems on the subject of high school gas kinetic theory based on Polya stages. This research is a research & development study using the 4D development model. Internal trials were conducted on 2 experts and 1 learning practitioner, while empirical trials were conducted on 81 students. Internal trial data were obtained through questionnaires and analyzed using descriptive analysis techniques, while empirical test results were obtained through test techniques and analyzed following the Rasch Model (RM) using the QUEST program. The results showed that at the internal test stage all items were stated to be very good in measuring the ability of solving physical problems. Empirical test results, as many as 5 out of 5 items were declared fit, with instrument reliability of 0.63 (high category). The level of difficulty of the items varies, some are easy and difficult. And the distinguishing power of all items included in either category. Thus, 5 test instruments developed were stated to meet the requirements and were appropriate to be used to measure the ability of solving physical problems based on Polya's stages.

Abstract

This study aims to investigate the effectiveness of metacognitive learning strategy assisted by student worksheets based on troubleshooting even though only for a short amount of time to develop students' physics problem solving abilities. This research design using quasi-experiment design. The study population was students of class XI MAN Yogyakarta 1 with two sample classes totaling 53 people taken through cluster random sampling techniques. Collecting research data through study documentation, observation, and tests. Analysis of research data using descriptive analysis techniques and quantitative analysis (independent sample t-test). This study shows the results that the application of metacognition learning strategy assisted by student worksheets based on troubleshooting in a relatively short period of time is not effective to produce physics problem solving abilities.
