The Effect of Research Based Learning Management in the Topic of Plantae Kingdom on Learning Achievement and Critical Thinking Ability in the Second Year of the General Science Students at Chandrakasem Rajabhat University

Abstract

This research aims to study the learning achievements of Plant kingdom and the critical thinking abilities of before and after classes between control groups and experimental groups that have been managed by regular learning and research based learning in second-year students in general science education of the 2019 academic year, Chandrakasem Rajabhat University. The experimental groups with 30 students were organized to learn using research based, and a control group that organized regular learning for 24 people.

The tools used in the research were (1) two research-based learning management plan s and two regular learning management plans, with 9-hour per plan, (2) a plant kingdom science achievement test, and (3) The critical thinking ability test. The statistics used in the research include average, median, standard deviation, Analyzing the learning achievements and the critical thinking abilities before and after class with Wilcoxon signed rank tests and studying changes in inference, recognition of assumption, deduction, interpretation and evaluation of argument with box-whisker charts.

The results showed that (1) the learning achievements and the critical thinking ability of the experimental group and the control group, the median of after classes is higher than before class at .01 level (2) the critical thinking ability was found that after learning, the experimental group had a higher median in inference and interpretation ability than the control group. While the ability to deduction, recognition of assumption and evaluation of argument showed that control groups and experimental groups had the same median. Therefore, research-based learning management is an alternative way to improve student science achievement and critical thinking abilities.
