THE DEVELOPMENT OF THAI READING COMPREHENSION SKILL ACCORDING TO USING 5E INQUIRY AND INSTIGATION FLIPPED CLASSROOM FOR SECONDARY SCHOOL STUDENTS

5E inquiry instruction model combined with flipped classroom was active learning instruction, which involved assigning tasks, learning materials, and homework to students in flipped classroom to enhance students’ reading comprehension skill. The samples were grade 9 students at Wat Makluea School (Kanchanalakwittaya). The student’s academic year was 2023, with purposive sampling. The research tools consisted of six learning lesson plans, and 2) pretest data were collected for testing before studying. The learning activities were conducted for six weeks, totaling 18 classes and post-test. Data were analyzed using statistics including mean and standard deviation and dependent sample t-test. The results were showed that: 1)The development of learning activities by creating lesson plans for reading comprehension from tales, literature, articles, short stories, documentaries, and royal speeches. Each lesson plan was in three hours to divide the time into a 1:2 ratio, for allowing students to learn by themselves through a flipped classroom for one hour and through 5E inquiry-based learning model for two hours. 2) The efficiency of the 5E inquiry-based learning activities was in combination with flipped classroom. The E1/E2 efficiency was 80.09/79.72, per the performance criteria set at the 80/80 level. 3) The student’s reading comprehension skills after learning were significantly higher than before at a level of .05, with the effect size of the independent variable on the dependent variable at a high level.
