Forensic Investigation Context-Based Learning to Enhance Scientific Explanation Ability in Genetics for Grade 9 Students
Keywords:
Context-Based Learning, Scientific Explanation Ability, GeneticsAbstract
.This research aimed to 1) compare ninth grade students' learning achievement in genetics before and after learning through a forensic investigation context-based learning, 2) compare students' scientific explanation ability in genetics with the 80 percent criterion, and 3) examine students' satisfaction with this learning approach. This study employed a quasi-experimental one group pretest-posttest design. The sample consisted of 36 ninth grade students. The research instruments included 1) learning activities using forensic investigation context-based learning (comprising 3 contexts related to genetics), 2) a genetics achievement test, 3) a scientific explanation ability test, and 4) a satisfaction questionnaire. The results showed that 1) students’ post-test mean score on genetics achievement was significantly higher than the pre-test score at the .01 level. 2) The mean score of students' scientific explanation ability in genetics was significantly higher than 80 percent criterion at the .01 level. 3) Students’ satisfaction with the forensic investigation context-based learning was at a high level. This research revealed that forensic investigation context-based learning can enhance content understanding and application of content to explain contexts by emphasing the identification of related claim, evidence, scientific reasoning.
