PENGARUH MODEL PROBLEM BASED LEARNING BERPOLA DALIHAN NA TOLU TERHADAP KETERAMPILAN KOLABORASI DAN BERPIKIR KRITIS SISWA PADA MATERI KOMPONEN EKOSISTEM DAN INTERAKSINYA KELAS X SMA SWASTA AL MANAR MEDAN

Abstrak

The Problem Based Learning model Dalihan Na Tolu is a biology learning model that integrates the Batak social system into the learning process. This study aims to (1) determine the effect of Problem Based Learning model Dalihan Na Tolu on students' collaboration skills on the material of ecosystem components and interaction class X at SMA Swasta Al Manar Medan (2) determine the effect of Problem Based Learning model Dalihan Na Tolu on students' critical thinking skills on the material of ecosystem components and interaction class X at SMA Swasta Al Manar Medan. The type of research used in this research is quasi experinental design with non-equivalent control group design. Before conducting the research, the instrument was validated first. For data analysis in this study using prerequisite tests and hypothesis testing. Based on the results of the study, the sig level value for the Mann Whitney hypothesis test from the student posttest was 0.000 and the sig level value for the Independent sample t test hypothesis test from the student collaboration skills observation sheet was 0.000. Thus it can be concluded that (1) There is a significant effect of Problem Based Learning Model Dalihan Na Tolu on students' collaboration skills on the material of ecosystem components and their interaction in class X SMA Swasta Al Manar (2) There is a significant effect of Problem Based Learning Model Dalihan Na Tolu on students' critical thinking skills on the material of ecosystem components and interaction in class X SMA Swasta Al Manar.
