Experimentation of Brain Based Learning Model Based on Lesson Study Learning Community Towards Students’ Reasoning Ability on Sequences and Series Material

Abstract

The purpose of this research is to know How to process of teaching learning using Brain Based Learning which based on Lesson Study Learning Community as well the effect on students’ reasoning abilities on the material sequences and number series at SMAN 5 Jember. The kind experiment that is used is mixed methods or methods that combine quantitative and qualitative methods, which refer to knowing whether there is an effect of students’ reasoning abilities. The experiment of this research is Quasi Experiment the population being experiment is the students of XI MIPA, then a sample was taken so that XI MIPA 1 was the experimental class and class XI MIPA 2 was the control class. The techniques collection data is used are test, observation, and interview. The result of t independent shows T table < Tvalue, with Tvalue = 3.204 and Ttable = 2.000, so that when H0 is refused H1 is accepted. It is proved that the positive influence from Brain Based Learning applied based on Lesson Study Learning Community with the capability of students’ reasoning skills on sequence and series materials.
