Abstract

This study aimed to know the effect of using PhET virtual laboratory towards students’ higher order thinking skills on linear motion. This research is quasy experimental research that uses the static group pretest-posttest design. The population of this research is all grade VIII students of MTsN mbon in the academic year 2021/2022 and the sample of this research is grade VIII4 as experimental group and VIII5 as control group that determined by simple random sampling technique. The instrument that used to collect the data is test HOTs that made in terms of multiple choices test. The data is analyzed by statistical formula of N-gain and t-test by SPSS 26. The result of N-gain of experimental group HOTs is 0.40 and control group is 0.19. The result of t-test shows that tcount of HOTs is 7.762 ≥ ttable is 2.000. It means that there is a significant difference of HOTs of students on the linear motion. Therefore, it can be concluded that the use of virtual laboratorial PhET has positive effect towards high order thinking skill of students on the linear motion

Abstract

This study aims to analyze the characteristics of the items based on the classical test theory approach. This research is exploratory research with a quantitative approach. The data used in this study were data from the 2015 Science Subject National Examination for Junior High School in Daerah Istimewa Yogyakarta (DIY) province. The samples taken in this study were 9054 students. Test takers are grouped into high groups and low groups based on the total score obtained. Estimation of item parameters using Excel and QUEST. The results of the analysis show that based on the classical test theory approach, the average item difficulty level ) in the high group is in the easy category, while in the low group, it is in the medium category, the average item differential index ( ) shows that the test ability to distinguish students with high abilities and low abilities in both the high and low groups is in the unfavorable category; and the reliability coefficient of the test (ρ) in the high group has high reliability, and the low group has perfect reliability

Abstract

This research is based on the limited learning resources that students can use independently. This research aims to develop an ethnoscience-based science module on the process of refining eucalyptus oil to determine the feasibility, practicality, and effectiveness of the module in reducing student misconceptions. The method used was research and development R&D. The research data obtained was analyzed using percentage descriptions. The results of the science module feasibility test showed that the feasibility of the material obtained a score of 88% with very feasible criteria. The feasibility of the media obtained a score of 89% with very feasible criteria. Furthermore, the feasibility of language obtained a score of 80% with appropriate criteria. The practicality of the module was tested through analysis of student responses to the module developed and a practicality score of 87% was obtained with very good criteria. This means that the ethnoscience-based science module developed has very good practicality in terms of a) attractiveness of the module, b) ease of use, c) ease of understanding the contents of the module, d) completeness of the contents of the module, and e) conformity with character values ethnoscience. According to the results of the analysis of learning outcomes tests accompanied by the Certainty of Response Index, it shows that the level of student misconceptions has decreased by 34% accompanied by an increase in the level of student understanding of concepts by 37%, and students who do not understand concepts have decreased by 3%. This shows that the module developed is effective in reducing student misconceptions
