Abstract

The purpose of this study was to determine student learning outcomes with the application of the probing prompt learning model supported by multimedia, to determine the interaction of students in learning and the relationship between the model and learning media with the material. The research design used is a pre-experimental design where the research uses only one class (experimental class) without any comparison class or control class. Data collection was done by giving a pretest before the learning process was carried out, and a posttest after the learning process. The research data obtained in the form of the difference in the average value of the pretest and posttest, the average value of the pretest is 31.57% and the average value of the posttest is 84.20%. Furthermore, the analysis of learning outcomes on colloidal material also shows an increase, in terms of the N-Gain analysis obtained 0.76 with high criteria and hypothesis testing which shows that t-hitung > t-tabel which means that the probing prompting learning model is supported by multimedia providing improvement of student learning outcomes.

Abstract

This study uses the Research and Development (R&D) method. The purpose of this research is to develop and determine the quality of powerpoint-assisted learning media. The research subjects were students of class X MIA 3 at SMA Catholic Don Bosco Bitung. The validation test of the four learning media assessment teams obtained 78.5% results, the material assessment team's validation test obtained 79.8% results. The overall results from the validation of the media assessment team and the material assessment team obtained an average result of 79.2% in the valid assessment category. The results of the teacher's response obtained a total score of 44 with an average of 88% included in the very interested category. The results of the first trial of 5 students obtained an average percentage of 36% of students who answered Strongly Agree, 52% of students who answered Agree, 10% of students who answered Disagree, 2% of students who answered Disagree, and 0% Strongly Do not agree. The results of the second trial of 10 students after repairs were made, the average percentage obtained was 67% of students who answered Strongly Agree, 33% of students who answered Agree. Based on the results of the responses of the two groups, it can be concluded that there was an increase in the large group
