Improving The Ability of Vocal Group Through POMP2E Model Development for Students of Junior High School

Abstract

This research aims to develop a POMP2E learning model that is valid/feasible, practical, and effective for use in learning the art of music in junior high schools. The type of research is Research & Development using the research and development procedures of the Gall, Gall & Borg model which was adapted from the Dick, Carey & Carey model. The research sample consisted of class IX students of SMP Negeri 1 Dolok Masihul as a group to test product practicality through one-on-one trials, small group trials (limited) and large group trials (field). Class IX students of SMP Negeri 3 Dolok Masihul tested product effectiveness through small group and field group tests. The data analysis techniques used were qualitative and quantitative descriptive data analysis techniques as well as experimental data analysis. Qualitative and quantitative data analysis is used to analyze model development data, namely testing instrument validity and product validity. Experimental data analysis is used for the validity and reliability of the tests used and the t test to see statistical differences in results between the experimental class and the control class. The results of testing the feasibility of supporting equipment instruments for the POMP2E model obtained a calculated average of 0.853, including the very feasible category. The results of the feasibility test for all POMPO2E model supporting device products obtained a calculated average of 0.874, including the category of very suitable for use. The results of the practicality test of using the POMP2E learning model and all supporting tools developed according to teacher responses obtained an average score of 89.32% in the very practical category, according to practicality according to students the average score was 88.56% in the very practical category. The results of the effectiveness test on the use of all POMP2E learning model products which were developed through three testing aspects, namely the cognitive, apective and psychomotor aspects, showed that the results of the POMP2E learning model's cognitive aspect effectiveness test were obtained N-Gain=0.73, including the high category with the interpretation of the category being quite effective in use. . The results of testing the effectiveness of the affective aspect of the POMP2E learning model obtained N-Gain=0.84, which is in the high category with the interpretation that it is effectively used. The results of testing the effectiveness of the POMP2E learning model for psychomotor aspects obtained N-Gain=0.76, which is in the high category with the interpretation that it is effective to use. Thus, it can be concluded that the POMP2E learning model developed is effective in improving the vocal abilities of groups of junior high school students.
