THE DEVELOPMENT OF MICROLEARNING BY USING CONSTRUCTIVSM TO ENHANCE ENGLISH VOCABULARY ACHIEVMENT OF GRADE 12 STUDENTS

Abstract

This research article is about the development of microlearning by using constructivism to enhance the English vocabulary learning achievement of Grade 12 Students. The research objectives were to: 1) develop a microlearning by using constructivism to enhance the English vocabulary learning achievement of grade 12 students, 2) To compare pre-learning test results with post-learning effectiveness after using microlearning lessons based on constructivist concepts to enhance English vocabulary achievement of grade 12 students. The target group for this research consisted of 34 twelfth-grade students from Satri Angthong School. In the first semester of the 2023 academic year, obtained using cluster sampling, the research followed an experimental approach, using the following research tools: 1) Microlearning 2) Achievement Test 3) Quality assessment forms. In terms of data analysis, the researchers utilized percentage, mean, standard deviation, and t-test statistics. The research findings revealed: 1) The constructivist microlearning lesson aimed at enhancing students' English vocabulary learning achievement of grade 12 students. Expert evaluations positively rated the content (mean= 4.44) and technical aspects (mean= 4.54) of the lesson. Moreover, the efficiency level reached 83.33/82.83, surpassing the criteria of 80/80. 2) Significant academic improvement was noted following students' participation, highlighting substantial progress. The improvement reached statistical significance at the .01 level.
