Abstract

This study aims to produce an inquiry-based physics learning device to train high school students science process skills on the subject of material elasticity. The research design uses Kemp model tested in three classes of class XI MIA- 1 , class XI MIA- 2 , and class XI MIA- 6 with total number of students of 90 in SMA Negeri 5 Ambon, second semester of  academic year 2017/201 8.  Group pretest-posttest design was used for test design.  Data analysis techniques used include, 1) Qualitative descriptive analysis including validation result, readability level, Lesson plan implementation, students activity, learning constraints, science process skill result , and response. 2) Parametric statistical analysis includes: normality test, homogeneity test, and t-test. Finding showed that, 1) validity of learning tools developed is categorized as valid ;  2) the effectiveness of instructional tools in terms of: (a) the attainment of science process skills in the three classes obtained a significant increase in science process skill on each indicator studied by the researcher; (b) The student's response to the device and the learning implementation is very positive with the highest percentage is with teacher guidance when working on worksheet. Based on the finding, physics learning device by using inquiry model to train the students' science process skill which has been developed has met the criteria of validity, practicality, and effectiveness that it is feasible to be used to train students' science process skills on materials elasticity

Abstract

This study aims to produce physics teachinginstruments with cooperative learning model type group investigation to improve students self-efficacy and learning achievement. Development of teachinginstrumentsusing Kemp model. The experimental design uses a one-pretest-posttest design model with three time replications. Subjects in this study are teachinginstruments and students of class XI MIPA. This research was conducted at SMA Negeri 3 Singaraja-Bali in the academic year of 2017/2018. Data were collected using validation method, questionnaire, observation, questionnaire and test. Data analysis techniques used are qualitative descriptive analysis and parametric statistical analysis. The results showed that the developed teachingintruments were valid, practical, and effective.The validitywas indicated by the average scores in a good categoryforlesson plan, BAS, student worksheet, achievement test and self-efficacy questionnaire.The practicisibilitywas showed by: (a) a good implementation of the lesson plan, (b) student activity is in excellent category, (c) the readability of BAS and student worksheet are in moderate categories, and (d) the obstacles during the learning activities can be overcome.The effectiveness was indicated by: (a) students learning achievement has increased significantly; (b) students self-efficacy has increased significantly; and (c) students respond is positive to the learning instruments and learning activity.  In conclusion, physics learning instruments with cooperative learning model type group investigation can be used to improve students self-efficacy and learning achievement.
