Abstract

This study focuses on the development of a physics problem-solving skills test instrument on dynamic fluid material for grade XI high school students. The purpose of this study is to determine how to develop a problem-solving-based test instrument on dynamic fluid material and to determine the feasibility of a problem-solving-based test instrument on dynamic fluid material. The type of research used in this study is R & D (Research and Development) development research using the ADDIE research model which has a research design through four stages, namely Analysis, Design, Development, Implementation and Evaluation. The trial sample in this study was 29 grade XI students of Taruna PBD Medan High School with the assumption that the entire class is homogeneous. The research instrument used is a problem-solving skills test consisting of 7 questions in the form of essays. The trial results were obtained from the problem-solving ability test instrument in the validation test conducted by 3 validators who had a very high value category which was included in the category of suitable for use with revision. Analysis of the problem-solving ability instrument administered to 29 students, with the results obtained in the validity and reliability trials, showed that all test instruments were valid and reliable. In the trial, the difficulty level of five questions was classified as moderate, one was classified as easy, and one was classified as difficult. Furthermore, in the discrimination test, the seventh question was categorized as excellent. Thus, the developed test instrument was suitable for use with five questions. So it can be concluded that the development of instruments based on students' problem-solving abilities is suitable for measuring students' thinking abilities.

This research objective (1) Find out the effect of the group division in the TAPPS learning model of students' ability to solve problems; (2) Determine the improvement of students’ problem-solving ability after group division in the TAPPS learning model is applied; (3) find out the effect of group division in the TAPPS learning model on students’ learning outcomes; (4) Determine the improvement in the students’ learning outcomes after group division in the TAPPS learning model applied. The subjects of this research were students at SMA Islam Al Ulum Terpadu Medan consisting of two classes. X MIA 1 consists of 28 students who will be divided into 3 group divisions with different numbers of members. X MIA 2, formed of 30 students will also be divided into 3 group divisions with different numbers of members. The type of research was a true experiment to determine the effect of group division in the TAPPS model for the subject. The data collection instrument used in this research consisted of a problem-solving test with 10 essay forms that had been validated by three experts. The data analysis techniques used in this study are quantitative. The results of this study (1) There is an effect of group division in the TAPPS learning model on students’ problem-solving ability on momentum and impulse topics. (2) The improvement can be seen from the one-way ANOVA that was used to see the significant difference in the average score between all pairs in the pretest and all pairs in the posttest. The p-value in both correctors is smaller than 0,05 (0,000 < 0,05) (3) There is an improvement in students’ problem-solving ability, to the improvement of students’ learning outcomes. (4) The improvement can be seen from the n-Gain test was used to see the difference between pretest and posttest final values in every group division. The interval of n-Gain between group divisions is 0,32 – 0,40. this value is included in the medium category, which is (0.30 ≤ n-Gain ≤ 0.70). so, based on these results, the group division in the TAPPS learning model can improve student learning outcomes on momentum and impulse topics.
