THE EFFECTS OF ACTIVE LEARNING ACTIVITIES AND JOURNAL WRITING ON MATHEMATICAL REASONING ABILITIES ON PARALLEL LINES OF GRADE 8 STUDENTS

Abstract

          The purposes of this research were to study 1) mathematical reasoning abilities of grade 8 students after applying active learning activities and journal writing and 2) students’ opinions towards active learning activities and journal writing on parallel lines. The sample group consists of 40 students from one classroom of grade 8 in second semester of academic year 2019 from a school in Bangkok. Researcher used cluster random sampling method. The instruments were 1) 10 lesson plans applying active learning activities and journal writing. 2) assessment test on students’ mathematics reasoning abilities on parallel lines with reliability of 0.85 and 3) questionnaire on students’ opinions towards active learning activities and journal writing. The statistics used for analyzing data included percentage and mean
          The research results revealed that 1) Mean score of the mathematics reasoning abilities of grade 8 students through active learning activities and journal writing on parallel lines post - test was 11 and 2) most students suggested that learning by active learning activities and journal writing was fun. They were able to review the lessons they have learned. Active learning activities and journal writing help students memorize and better understand the theories of parallel lines.
