This research developed four-tier multiple choice test items to measure its validity, reliability, characteristics, and students’ misconceptions on Simple Harmonic Motion material. This research was Research and Development (R & D) using 3D (Define, Design, and Develop) development model. The tenth graders of 1 Slawi Senior High School participated in tryout test and the eleventh graders of 1 Kramat Senior High School participated in the final field test. This research used documentation, interviews, questionnaires, and tests to collect the data. The developed test consisted of 30 four-level multiple choice items covering questions, the level of confidence in answering questions, reasons, and the level of confidence in giving reasons. This research yielded validity, reliability, discrimination power, difficulty level, and the percentage of misconceptions analyses. Validation results from 8 validators stated that the instrument was very feasible with the average percentage of 86.23%. The content validity result using Aiken coefficient got the average score of 0.80 with the valid category at the 0.05 significance level. The reliability of the developed test was 0.892. The difficulty level indicated 5 easy items, 22 medium questions, and 3 difficult questions. Students experienced misconceptions on Simple Harmonic Motion material of 58.63% in the medium category.
Cookbook experiment is familiar type of experiment in which students have to follow some procedures to carry out a practicum in laboratory. Due to its easiness, not only students in high school but also students in college recognized this. However, there is no clear role of cookbook experiment toward learning outcomes of pre-service physics teachers. This study investigates the impact of cookbook experiment toward learning outcomes. A single case study was carried out in one private university in east Indonesia in which all participants were students from physics department. The finding results reveals that cookbook experiment was used almost eight years. This affected two pivotal aspects of students: achievement of cognitive learning ability and students’ interest toward learning process. In these aspects context, the cookbook experiment did not facilitate students who are pre-service physics teachers to construct and strengthen deep understanding, to make a joyful and meaningful learning process, and to flourish the diverse skills needed by students such as higher order thinking skills. This article indeed presents a consideration of the implication of physics practicum in Indonesia in deep insight and wider context.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
