development of appropriate learning models must be carried out. The aimed to of this
study were analized validity, effectiveness, and practicality of STEM-based Team
Games and Tournament (TGT) learning model towards the students' science process
skills. This research was research and development (RnD) with a 4-D development
namely; Defining, Designing, Developing, and Disseminating. The study involved 2
experts as validators, 2 teachers as user, and 112 students in small-scale tests, largescale tests, and distribution tests in SMA. The research was done until the stage of
disseminating and produced. The results showed the validity value of 83% was
categorized as very valid, the effectiveness score of 83.9% was categorized as good,
and the practicality score was 87.5%, so that it was declared valid, effective, and
practical to improve the science process skills. Therefore, it is recommended to be
applied in schools. | en_US |
