This paper reported a harmonic oscillation learning tool device using accelerometer sensors in smartphones "Osci-Meter" to improve high school students' analytical thinking skills. Three practice activities have been tested: the relationship of rubber constant with frequency, the relationship of mass with the period, and analyzing the graph of position, velocity, and acceleration versus time of harmonic oscillation. The research and development model was ADDIE (analyze, design, develop, implement, and evaluate). The feasibility test of the device was conducted on subject material experts, media experts, and instructional experts. Based on the results of the feasibility test, the score from the subject material expert, the media expert, and the instructional expert was 79.75%, 92.71%, and 81.21% respectively. The field test results on the high school students obtained 87,81% in the first field test and 86,22% in the second field test. The normalized gain (n-gain) test obtained an average gain score of 0.313 in the first field test and 0.351 in the second field test that indicated the learning tool device could improve students' analytical thinking skills with moderate interpretation. Based on the feasibility test and effectiveness test, it concluded that the proposed oscillation motion learning tool device "Osci-Meter" could improve students' analytical thinking skills in high school physics learning process.

Important fundamental concepts in magnetostatics are the magnetic field and the magnetic force. However, students often experience misconceptions about these concepts because of differences in their understanding and interpretation. In this study, a learning tool is designed to demonstrate the inductive magnetic force to objects due to an induced magnetic field. This learning tool is an integrated system consisting of a magnetic sensor, an Arduino microcontroller, and an electric coil. To demonstrate the magnetic force, an object of mini cylindrical metal is inserted into a straw that is placed in the electric coil. The experimental data show a positive correlation between the object displacement with magnetic field strength, as well as magnetic fields to the electric currents in the coil. This toolkit may be used as a magnetostatic learning tool for students in high schools. [ABSTRACT FROM AUTHOR]

This study aimed to determine the effect of inquiry learning models and learning motivation on students' metacognition. The study used the quasi-experimental research method with the 2x2 treatment by level model. The subjects of this study were high school students in Grade 11. The samples were divided into two groups; one group learned through the open inquiry learning model while the other group learned through the guided inquiry learning model. Both groups were then given a learning motivation test to divide students into categories of students who had high learning motivation and students who had low learning motivation. The research showed that the metacognition of students who learned through the open inquiry learning models was lower than those who learned through the guided inquiry learning models. Also, the metacognition of students who had high learning motivation was greater than students who had low motivation. The results of the hypothesis test indicated that there is a significant difference in metacognition between students who learned through the open inquiry learning model and students who learned through the guided inquiry learning model, and there is a significant interaction effect between learning models and learning motivation on students' metacognition.
