Comparison of Number Head Together (NHT) Model and Discovery Learning Model Based Scientific Approach Towards VIII Grade Students’ Learning Outcomes in Biology Cognitive Competence in SMP it Darul Hasan Padangsidimpuan

Abstract

This study compared Number Head Together (NHT) and Discovery Learning learning models based scientific approach at the Darul Hasan Padangsidimpuan School of Integrated IT Middle School towards the learning outcomes of biology in grade VIII. This study used a quasi-experimental approach and the research design used was The Static Group Comparison Design. Sampling was done by purposive sampling technique, so that the selected class were class VIII-C (experimental group I) and class VIII-D (experimental group II). Instrument used was a written test in form of multiple choice test, while data ofstudents’ cognitive competence were analyzed using t-test.

Based on the final test results, it can be concluded that there are significant differences between Number Head Together (NHT) and Discovery Learning based scientific approach in students’ cognitive competence. Students’ cognitive competence using Number Head Together (NHT) model is higher than using Discovery Learning model.
