การสร้างเลิร์นนิงอ็อบเจกต์วิชาคณิตศาสตร์ เรื่อง การหาพื้นที่ผิว ของรูปเรขาคณิตสามมิติ สำหรับนักเรียนชั้นมัธยมศึกษาปีที่ 3

Abstract

The purpose of this independent study was to construct the Learning Object in Mathematics on the Surface Area of Three Dimensional Geometric Figures for Mathayom Suksa 3 Students. The subject of the study was a group of 60 Mathayom Suksa 3 students in Tonkaewphadungpittayalai School, the school of Chiang Mai Provincial Administrative Organization, who were studying in the first semester of school year 2015. The instruments used in this study were the Learning Object (created by the author) in Mathematics on the Surface Area of Three Dimensional Geometric Figures and the questionnaire of this Learning Object. After using the learning object, the subjects were asked to fill out the questionnaires. The data were analyzed and presented through the Mean (x) and Standard Deviation (S.D.). According to the results, it stated that the subjects gave a high preference to the multimedia screen design which had a x= 4.55 as compared to the design of instruction and content which had a x= 4.81 and the use of Learning Object with a x= 4.83. This meant that the graphics were beautiful and meaningful. In addition, the buttons were appropriately positioned and easy to use. The link for entering to the activities is easy. The subjects had a good participation in the activities by choosing the geometrics figures by themselves. Also, using this Learning Object helped students better understand math concepts such as the surface area of three dimensional geometric figures. Moreover, the subjects thought that integrating Learning object to the math subject was interesting and fun. The subjects enjoyed using the Learning Object in Mathematics on Surface Area of Three Dimensional Geometric Figures.
