Abstract

The research and development have been done to develop student worksheets (LKPD) based on predicting, observing, and explaining (POE). The development research model used refers to the ADDIE development model which consists of 5 stages: analysis, design, development, implementation, and evaluation. The assessment of product quality of LKPD development results carried out by validator and 14 physics teachers. The percentage of eligibility obtained from each validator and physics teacher is 77% and 83%. The test implementation of LKPD products applied to 20 students of class X MIA 2 SMAN 3 Unggul Sigli that chosen by purposive sampling. The results of a POE-based LKPD testing can improve the students’ critical thinking skills. Based on these results, it can be concluded that POE-based LKPD developed with the ADDIE development model is decent to be implemented. An investigation on a broader scale should be undertaken to assess the effectiveness in teaching physics.

Abstract

The scarcity of experimental activities is one of the challenges of teaching current physics. This study resolves these issues and suggests three nuclear physics experiments using a low-cost ion chamber, whose construction is explained: the measurement of 222Rn progeny collected from the indoor air; the measurement of the range of alpha particles emitted by the 232Th progeny, present in lantern mantles and in thoriated welding rods, as well as by the air filter containing 222Rn progeny; and the measurement of 220Rn half-life collected from In this study, the experimental methods and anticipated findings are presented, showing that the experiments could help nuclear physics curricula. These procedures may provide broad access to either academic laboratories in high schools or colleges and the equipment may be used to create novel nuclear physics teaching strategies
