The Impact of Flipped Classroom Instructional Model in Teaching English as a Second Language (ESL) Among Lower Secondary Pupils

English is a global language that most people use all around the world. English is the second language vastly used as a communication tool in daily life in Malaysia. It is also a compulsory subject to learn at schools from primary school to secondary school. However, many second language learners may have higher possibilities of facing various challenges in learning English as a Second Language (ESL) in Malaysia. Hence, the purpose of this study was to compare the flipped classroom and traditional classroom teaching approaches in secondary school pupils’ overall English language performance in these particulars: Grammar, Reading, and Writing, as well as to evaluate the perceptions of flipped learning experience among lower secondary pupils in learning ESL. The study was conducted quantitatively with a quasi-experimental method set in pre and post-tests design and consisted of 50 pupils separated equally into control and experimental groups. Seven weeks of lessons were conducted for both control and experimental groups. One-way analysis of covariance (ANCOVA) was used to adjust the pre-test scores of experimental group and study whether there are any significant differences on the effectiveness by implementing flipped classroom approach in experimental group despite the covariate (pre-test score) exists.After the post-test was conducted in the experimental group, the pupils were given a set of questionnaires containing 14 items to respond to and gauge their perceptions of flipped classroom learning experience based on motivation, effectiveness, engagement, and satisfaction. Findings reveal that the pupils in the experimental group achieved higher scores than the control group on their post-test scores in learning Grammar, Reading, and Writing by implementing a flipped classroom teaching approach. Also, the questionnaire's evidence indicated that most of the pupils had favorable perceptions of flipped classroom learning experience in the experimental group. This study indicates that flipped classroom teaching approaches positively enhanced pupils’ academic performance and learning experience.
