Abstract

This research article aimed to: 1) compare the English sentence writing skills of Grade 7 students after using the 2W3P Instructional Model combined with Skill Practice Sets against the 80 percent criterion, 2) compare the English sentence writing skills of Grade 7 students before and after using the 2W3P Instructional Model combined with Skill Practice Sets, 3) study the satisfaction of students toward using the 2W3P Instructional Model combined with Skill Practice Sets. This research was an experimental research. The population comprised 106 Grade 7 students from 5 classrooms at Hatyaiwittayakarn School in the first semester of the academic year 2025. The sample was 24 students from Grade 7/2 classroom, obtained by simple random sampling with drawing lots. The instruments included the 2W3P lesson plans combined with a skills training kit, an achievement test, and a satisfaction questionnaire with 20 items, each having a content validity index between 0.67-1.00. The statistics used for data analysis were mean, standard deviation, and mean comparison. The research findings revealed that: 1. The students' English sentence writing skills after using the 2W3P Instructional Model combined with Skill Practice Sets were higher than the 80 percent criterion with statistical significance at the 0.5 level (mean = 16.79), which confirmed the hypothesis. 2. The students' English sentence writing skills after learning were higher than before learning with statistical significance at the 0.1 level, with the post-learning mean score (16.79) higher than the pre-learning mean score (8.54), which confirmed the hypothesis. And 3. The students' satisfaction toward this instructional approach had a mean of 4.05, which was at a high level.
