ผลของการจัดกิจกรรมการเรียนรู้คณิตศาสตร์โดยใช้รูปแบบการเรียนการสอนคณิตศาสตร์ที่เน้น ความเข้มข้นของมโนทัศน์ที่มีต่อมโนทัศน์ทางคณิตศาสตร์และความสามารถในการเชื่อมโยงความรู้ ทางคณิตศาสตร์ของนักเรียนชั้นมัธยมศึกษาปีที่ 4

Abstract

The purposes of this study were 1) to compare mathematical concept of students between the experimental group and control group, 2) to compare mathematical connection ability of students between the experimental group and control group, and 3) to compare mathematical connection ability of students learning by using an organizing mathematics learning activity Concept-rich Mathematics Instruction between, before and after learning. The subjects were tenth grade students of Samutsakornburana School in the second semester of the academic year 2015. There were 46 students in the experimental group and the control group. The instruments for data collection were concept test and mathematical connection ability test. The data were analyzed by arithmetic mean, standard deviation and t-test.

            The result of this study revealed that 1) mathematical concept of students in the experimental group were higher than students in the control group at a .05 level of significant,
2) mathematical connection ability of students in the experimental group were higher than students in the control group at a .05 level of significant, and 3) mathematical connection ability of students learning by using an organizing mathematics learning activity Concept-rich Mathematics Instruction, after learning was higher than before learning at a .05 level of Significant.
