The Effects of Flipped Classroom on English Grammar Proficiency of Thai EFL Students in Chiang Mai Province

Abstract

During the COVID-19 pandemic, teachers have faced the dual challenge of providing quality education, particularly in English grammar. As a consequence, this research attempts to improve the students' grammar proficiency by implementing the flipped classroom, which would ultimately solve all these problems. The study aimed to investigate the effects of the implementation of the flipped classroom on the English grammar proficiency of the students and to explore the students’ opinions on the implementation of the flipped classroom. The population in this study was composed of 26 Grade 9 students enrolled in the English language grammar course in the upper-secondary section at Wichai Wittaya School in the first semester of the 2022 academic year. The instruments used in the research were six learning management plans with the implementation of the flipped classroom, pre-and post-tests, an opinion questionnaire towards the implementation of the flipped classroom, and interview questions. The statistics used in the analysis were mean, standard deviation, and percentage.  The findings revealed that the post-test mean was higher than that of the pre-test with means of 23.33 and 12.63 respectively. It is concluded that the implementation of a flipped classroom enhances the students’ proficiency in their English grammar. Furthermore, the students expressed positive opinions through the implementation of the flipped classroom with a mean of 3.50.
