Development on Mathematical Reasoning of Brain-Based Learning Management of Secondary 2 in Educational Opportunity Expansion School Under The Office of The Sisaket Primary Educational Service Area Office 1

Abstract

The objectives of this research were as follows: 1) to develop brain-based learning management on geometric reasoning in Mathematics course of secondary 2 in Educational Opportunity Expansion School Under the Office of the Sisaket Primary Educational Service Area Office 1, to had efficiency according to the criteria of 80/80. 2) To compare the achievement of secondary 2 who received brain-based learning in the experimental group and the control group. In the school, opportunities were extended under the office of the Sisaket Primary Educational Service Area Office 1 3) to study the level of mathematical reasoning of secondary 2. The samples used in this study were two group of secondary 2 students in semester 2, academic year 2023. The experimental group was 1 classroom, 16 students from Ban Tamyae Nong Mek School. The control group was 16 students at Ban Puai Pracha Samakkhi School. Both schools were under the Sisaket Educational Service Office 1. Cluster Random sampling was used, using schools as the sampling unit. Tools used include learning management plans on Brain-based geometric reasoning for secondary 2, 12 learning plans 3 sets of reasoning behavior observation forms, 3 sets of during-class tests of the learning management plan,3 sets of tests measuring the level of mathematical reasoning, and 20 questions of achievement tests on mathematical reasoning. Statistics used Data analysis included percentage, mean, standard deviation and t-test

           The research results were as follow.

1. Organizing brain-based learning on geometric reasoning, Mathematics course of secondary 2 in Opportunity Expansion School Under the Office of the Sisaket Primary Educational Service Office 1, the efficiency was 84.79/81.25.
2. Achievement results of secondary 2 who received brain-based learning in the expanded opportunity school under the office of the Sisaket Primary Educational Service Area Office 1, the experimental group was higher than the control group statistically significant at the .05 level.

       3. Mathematical reasoning level of secondary 2 Most were Level 2, accounting for 56.25 percent, followed by Level 3 accounting for 18.75 percent, Level 4 and Level 1 accounting for 12.5 percent respectively.
