A Comparison of Grade 11 Students’ Critical Thinking Ability and Learning Achievement in the Subject of Genes and Chromosomes through the 7E Learning Cycle Model together with Instructional Multimedia

Abstract

The objectives of this research were 1) to compare grade -11 students’ pretest and posttest critical thinking ability through the 7E Learning Cycle together with instructional multimedia and 2) to compare the students’ pretest and posttest learning achievement in the subject of Genes and Chromosomes through the 7E Learning Cycle Model together with instructional multimedia.  The sample group consisted of 50 grade-11 students in Classroom No. 5/9, of Kanlayanawat School,          in Khon Kaen Province under the Secondary Education Service Area Office 25 during the second semester of the 2018 academic year.  The study followed the one-group pretest-posttest research design procedures for data collection and the research tools included 15 lesson plans on the subject of Genes and Chromosome based on the 7E Learning Cycle together with instructional multimedia,   a critical thinking ability test and a learning achievement test.  The collected data were analyzed by means of computing arithmetic mean, standard deviation and a t-test.

          The findings:

          1) The students’ posttest critical thinking ability through the 7E Learning Cycle together with instructional multimedia was significantly higher than their pretest ability at the .01 level of significance;

          2) The students’ posttest learning achievement in the subject of Genes and Chromosome through the 7E Learning Cycle together with instructional multimedia was significantly higher than their pretest achievement at the .01 level of significance.
