The CEFR-CLIL-Based language pedagogical innovation to enhance english competencies and autonomous learning ability among high school students
Abstract:
This research employed a Research and Development (R& ; D) design and aimed to: 1) develop and evaluate the effectiveness of the CEFR-CLIL-based language pedagogical innovation to enhance English competencies and autonomous learning ability among high school students (CEFR-CLIL+) ; 2) investigate students English language competencies following the implementation of the CEFR-CLIL+ innovation ; and 3) examine their autonomous learning ability after using the CEFR-CLIL+ innovation. The data collection process consisted of four phases: Phase 1 involved document analysis, needs assessment, and a survey of students interests and use of technology for English learning in high schools across Chiang Mai. Phase 2 involved the development of the CEFR-CLIL+ innovation. Phase 3 focused on the validation of research instruments, and Phase 4 on the refinement of the innovation prior to dissemination. The sample consisted of 20 English teachers and 850 high school students in Chiang Mai, along with 230 high school students from The Prince Royals College, all of whom participated in the initial survey. For the trial implementation, 20 students from class M.6/9 were assigned as the experimental group, and 42 students from class M.6/6 served as the control group. Both classes were from The Prince Royals College, Chiang Mai. Research instruments included a needs survey, four CEFR-CLIL+ learning units, the Autonomous Learning Assessment (ALA), and a Self-Assessment Form (SAF). Data were analyzed using frequency, percentage, mean, standard deviation, and paired-sample t-tests. The findings revealed that the CEFR-CLIL+ innovation was effective in enhancing English competencies and autonomous learning ability among high school students. A comparison of pre- and post-test scores showed that the experimental group significantly improved at the .01 level, with progress in reading (10.0052.50%), listening (2.5032.50%), writing (0.0015.00%), and speaking (2.5037.50%). The control group also showed statistically significant gains (p < ; .01), with improvements in reading (10.0062.50%), listening (2.5062.50%), writing (5.0032.50%), and speaking (5.0029.00%). According to CEFR-aligned assessments, the experimental group progressed from level A2 (mean score = 254.40) to B1 (mean score = 341.00), while the control group improved within level B1, from 316.35 to 362.24, both with statistically significant differences (p < ; .01). In terms of autonomous learning ability, both groups demonstrated higher post-test scores based on the Autonomous Learning Assessment. The Self-Assessment Form results indicated that the experimental group improved in all skills, whereas the control group showed gains in listening, speaking, and reading, but a slight decrease in writing. These results underscore the effectiveness of the CEFR-CLIL+ innovation and suggest that learner diversity and contextual factors should be considered in classroom implementation.
