ผลของการใช้เทคนิคผังกราฟฟิกในการเรียนการสอนวิชาวิทยาศาสตร์ ที่มีต่อการนำเสนอข้อความรู้ด้วยผังกราฟฟิก และผลสัมฤทธิ์ทางการเรียนของนักเรียนชั้นมัธยมศึกษาตอนต้น / ศิริลักษณ์ แก้วสมบูรณ์ = Effects of using graphic organizers technique in science instruction on presenting knowledge in graphic organizers form and learning achievement of lower secondary students / Sirilux Kaewsomboon
The purposes of this study were 1) to study the effects of using graphic organizers technique on presenting knowledge in graphic organizers form and science learning achievement 2) to compare science learning achievement of mathayom suksa one students between the groups learning by using graphic organizers technique and using formal teaching method. The sample were two groups of mathayom suksa one students of Navamintarachutis Bangkok. They were devided into two groups : an experimental group with 39 students and a control group with 41 students, learned by using graghic organizers technique and learned by using formal teaching method. The research instruments were 1) a science learning achivement test. The reliability of the science learning achivement test was 0.81, the difficulty levels were 0.18-0.77 and the discriminative levels were 0.22-0.73 2) a test of presenting knowledge in graphic organizers form. The reliability of the test of presenting knowledge in graphic organizers form was 0.70, the difficulty levels were 0.57-0.75 and the discriminative levels were 0.27-0.38. The collected data were analyzed by means of percentage, arithmetic means, standard deviation and t-test. The research findings were summarized as follows 1. The average score of presenting knowledge in graphic organizers form of the students learning by using graphic organizers technique was lower than 70 percent which was the criterion score. 2. The average score of science learning achievement of the students learning by using graphic organizers technique was higher than 70 percent which was the criterion score. 3. The science learning achievement of mathayom suksa one students learning by using graphic organizers technique was higher than those learning by using formal teaching method at the 0.05 level of significance
