The effectiveness of the laboratory work model based on senior high school students' learning outcomes and cooperative attitudes

This research aimed to determine the differences in learning physics using laboratory work and conventional learning models in learning outcomes and students’ cooperative attitudes and determine the more effective model of those two models. This research was quasi-experimental research using two classes, consisting of an experimental class that was given a learning model of laboratory work, and a control class that was given learning as usual in schools. Additionally, the research instruments included tests, questionnaires, and observation sheets. This research used MANOVA analysis, effect size, and Generalized Linear Mixed Model analysis design to test the research hypothesis. The results showed that there were no differences in student physics learning outcomes between laboratory work and conventional learning models. Hence, laboratory work models were not more effective than conventional learning models, there were differences in cooperative attitudes between students who used the laboratory work model and the others who used the conventional learning model with effect size in the high category, and the laboratory work model was more effective than the conventional learning model in terms of student attitudes.
