The Development of Consonant Cluster Reading Ability and Analytical Thinking Using GPAS 5-Step Learning Management for Sixth-Grade Students

Abstract

This research aimed to: 1) develop the ability to pronounce Thai consonant clusters through GPAS 5 Steps learning management for Grade 6 students, with a post-learning average score of not less than 75 percent and at least 75 percent of the students passing the established criterion; and 2) develop analytical thinking ability through GPAS 5 Steps learning management for Grade 6 students, with an average score of not less than 75 percent and at least 75 percent of the students passing the established criterion. The research employed purposive sampling. The target group consisted of 23 Grade 6 students studying in the second semester of the 2025 academic year at Ban Phai Saengthong Prachasan School. The research instruments included: 1) twelve lesson plans on the pronunciation of Thai consonant clusters using GPAS 5 Steps learning management, totaling 12 hours; 2) a test measuring the ability to pronounce Thai consonant clusters; and 3) a test measuring analytical thinking ability. The statistics used for data analysis were mean, standard deviation, and percentage. The findings revealed that: 1) the Grade 6 students achieved pronunciation ability in Thai consonant clusters with a mean score of 16.35 points, accounting for 81.74 percent, and 21 students, or 91.30 percent of the total number of students, passed the 75 percent criterion, which was higher than the predetermined criterion; and 2) the Grade 6 students demonstrated analytical thinking ability with a mean score of 15.87 points, accounting for 79.35 percent of the full score, and 18 students, or 78.26 percent of the total number of students, passed the established criterion.
