Developing Active Learning Activities Promoting Students' Mathematical Thinking in Mathayomsuksa 2

Abstract

The objectives of this research were (1) to develop and find out the effectiveness    of active learning activities; To teach statistics to be effective according to criteria 75/75    (2) to study the level of mathematical thinking. After receiving active learning activities to teach statistics in terms of problem-solving skills. reasoning skills and skills in presenting ideas (3) to study the level of mathematical thinking After receiving active learning activities  in teaching statistics, compared with the criteria of 75 percent (4), to study the opinions of experts on guidelines for developing active learning activities that promote mathematical thinking. The sample group used was Mathayomsuksa 2/1 students at Burapha Pittayakhan Municipal School. Maha Sarakham Province, Semester 2, academic year 2023, number students 27, which was obtained from cluster random sampling. The tools used included plans for organizing active learning activities. The mathematical thinking test and interview form statistics used in the research included percentages, means, and standard deviations. Data were analyzed using t-test statistics, single-group case analysis of written work, and analytical lectures. The results of the research found that (1) results of development and efficiency of active learning activities 75.61/79.81 which is higher than the criteria (2) mathematical thinking level after organizing active learning is at a moderate level Accounting for 70.22 percent (= 16.85, S.D.= 5.25) (3) Mathematical thinking level of students after receiving active learning activities compared to the criterion of 75 percent, higher than the criterion, with statistical significance at the .05 level (4) Guidelines for developing active learning management have found that teachers should emphasize providing situations. Interesting problems for students to practice and emphasize understanding the principles allow students to connect knowledge to explain and summarize answers on their own. Therefore, teachers should emphasize reasoning skills and skills in presenting ideas that are representative of students, which helps in developing students' mathematical thinking.
