การพัฒนาความคิดรวบยอด เรื่องภาคตัดกรวยของนักเรียนชั้นมัธยมศึกษาปีที่ 4 โดยใช้อินเทอร์แอคทีฟไวท์บอร์ด

Abstract

The purpose of this study was to develop the concepts on conic sections by usingInteractive Whiteboard in MathayomSuksa 4 level. The target group consisted of 25 students of MathayomSuksa 4/5 students in the second semester of the academic year 2014 at Chiang Mai University Demonstration school. The study was started by dividing the contents on conic sections to construct 4 learning activity as follow: Circle, Ellipse, Parabola, and Hyperbola. The tools used in the study included 8 learning activity plans, activity sheets, exercises, students’ journals, teachers’ notes and 4 concept tests. The collected data were analyzed in terms of percentage and analytical description. From this study, it was found that the learning activity units increased students’ understanding of each concept of conic sections. In addition, the students could plot graphs, identify parts of the graphs, and find the standard equation of conic sections. The students could also apply the gained knowledge to solve problems about conic sections more correctly.
