THE DEVELOPMENT OF ANALYTICAL THINKING AND SCIENTIFIC MIND BY USING GROUP INVESTIGATION LEARNING MANAGEMENT TOGETHER WITH MIND MAPPING FOR MATHAYOMSUKSA 3 STUDENTS

Abstract

The objectives of this study were  1) to compare the analytical thinking ability of Grade 9 students before and after participating in cooperative learning with inquiry-based groups combined with mind mapping techniques, 2) to assess the analytical thinking ability of Grade 9 students after participating in cooperative learning with inquiry-based groups combined with mind mapping techniques, and 3) to  examine the scientific mindset of Grade 9 students after participating in cooperative learning with inquiry-based groups combined with mind mapping techniques. The sample consisted of 26 Grade 9 students from Ban Tha Mai Lai School in the Chumphon Primary Educational Service Area Office 1, selected through cluster sampling using schools as units of randomization, during the second semester of the 2023 academic year. Research instruments included :         1) a cooperative learning plan with inquiry-based groups and mind mapping techniques, with a consistency index between 0.67-1.00; 2) an analytical thinking ability test, with a consistency index between 0.67-1.00, difficulty index between 0.33-0.95, discrimination index between 0.24-0.86, and reliability of 0.92; and 3) a scientific mindset questionnaire, with a consistency index between 0.67-1.00. The collected data were analyzed by mean, standard deviation, and t-test.

The results of this research were as follow:

1. The analytical thinking ability of Grade 9 students significantly improved after participating in cooperative learning with inquiry-based groups and mind mapping techniques ( X̅= 30.27, SD = 1.08) compared to before the intervention ( X̅= 16.88, SD = 1.15), with a statistical significance level of .05.

2. The study on the analytical thinking ability of Grade 9 students after participating in cooperative learning with inquiry-based groups and mind mapping techniques showed that the average score exceeded the 80% benchmark, with students achieving an average analytical thinking ability of 86.48%.

3. The study of the scientific mindset of Grade 9 students after participating in cooperative learning with inquiry-based groups and mind mapping techniques showed that, overall, the result was at a good level (X̅ = 4.23, SD = 0.13). When considering individual aspects, all were at a good level, ranked by average score from highest to lowest as follows: collaboration and assistance ( X̅ = 4.38, SD = 0.51), creative thinking ( X̅= 4.30, SD = 0.49), positive attitude towards science ( X̅= 4.12, SD = 0.83), and responsibility ( X̅= 4.11, SD = 0.56).
