Abstract

A quasi-experimental research has been conducted in Samarinda senior high schools. This research was conducted in the odd semester of the 2017/2018 academic year. The purpose of this research was to determine the effectiveness of the Problem-Based Learning based learning materials and conventional based learning material, ethnic, and the interaction of Problem-Based Learning material, and conventional based learning material and ethnic on biology concept gaining.

The instruments of this research were in the form of a questionnaire and a test. The data were analyzed using ancona with 5% significance level (p˂0,05). The results of ancova analysis indicate that learning model had a significant effect on biology concept gaining; ethnic and the interaction between learning model and ethnic did not have a significant effect on biology concept gaining. The senior high school biology teachers are advised to prepare and implement Problem-Based Learning based learning materials more frequently to empower the students biology concept gaining. Further similar research are necessary to obtain more information.
