Developing Critical Thinking Ability and Learning Achievement in Thai Language Using Organizing Learning According to the 4 MAT Combined with Mutimedia for Mathayomsuksa 4 Students

Abstract

The objectives of this research were: 1) develop critical thinking ability using the 4 MAT learning model combined with multimedia, with an average score of at least 70% of the total score and at least 70% of all students meeting the criteria; 2) compare Thai language learning achievement after using the 4 MAT learning model combined with multimedia to the criterion of 85% of the total score; and 3) study the opinions of 10th grade students regarding the 4 MAT learning model combined with multimedia. 
The sample consisted of 34 students from 10th grade, 13 at Phadung Naree School, selected using cluster random sampling. The research instruments used were 1) experimental instruments, including 4 MAT lesson plans combined with multimedia; and 2) data collection instruments, including 1) a critical thinking skills test, 2) an achievement test, and 3) a student opinion questionnaire. The statistical methods used for data analysis were percentage, mean, standard deviation, and t-test for one sample. 
The research findings were:
1) The average critical thinking ability score of students after learning using the 4MAT model combined with multimedia was 25.61 out of a total score of 30, which is equivalent to 85.36%. There were 34 students who met the criteria of 70% of the total score, representing 100%, which is higher than the established standard. 
2) The average post-learning achievement score of students was 26.74 out of the total score, which is significantly higher than the established standard of 85% of the total score at the .05 level. 
3) Students' overall opinions on learning using the 4 MAT model combined with multimedia were at the strongly agree level ( = 4.66, S.D. = 0.04)
The findings of this research conclude that the implementation of the 4 MAT learning management model integrated with multimedia effectively fosters the development of students' critical thinking ability. This approach enhances students' capacity for reasoned decision-making and problem-solving, consequently resulting in student learning achievement that surpasses the predetermined criterion.
