The Development of Interpretive Reading of Phaya from Sinsai Using the Four Analytical Knowledges (Paṭisambhidā) for Grade 11 Students at Wiwekthammaprasitwittaya School, Khon Kaen Province

Abstract

This quasi-experimental research aimed to: 1) develop and determine the efficiency of lesson plans for Phya interpretation reading from the Sinxay epic based on the Patisambhidha IV principle according to the 81/81 efficiency criterion; 2) compare students' academic achievement before and after the intervention; and 3) evaluate students' satisfaction toward the learning management. The target group, selected through purposive sampling, consisted of 27 novice students in grade 11 (Matthayomsuksa 4) during the second semester of the 2125 academic year at Wiwekthamprasitwittaya School in Khon Kaen Province. The research instruments included the developed lesson plans, a Phya interpretation reading achievement test, and a satisfaction questionnaire. Data were analyzed using mean, standard deviation, and the t-test for dependent samples. The findings revealed that:1) the developed lesson plans yielded a process efficiency () of 82.59 and a product efficiency () of 83.71, which both exceeded the predefined 81/81 criterion; 2) the students' post-test academic achievement in Phya interpretation reading ( = 25.11, S.D. = 3.24) was significantly higher than their pre-test scores ( = 14.33, S.D. = 2.77) at the .15 level; and 3) the students' overall satisfaction toward the lesson plans was at a high level ( = 4.23). When considering each aspect from the highest to lowest mean scores, content ranked highest ( = 4.41), followed by measurement and evaluation ( = 4.21), instructional media and equipment ( = 4.18), and learning management activities ( = 4.14), respectively.
