Abstract
To compare test scores in English-error detection between Thai high school students undergoing self-learning by an online tool (computer-assisted learning: CAL) with versus without tuition/lecture. This prospective, randomized, controlled study enrolled a sample of grade-12 high school students from a Thai secondary school. The predictor variable was the use of error-detection exercises in 9 separate 50-min tuition sessions during a 3-week period. Each subject was randomly assigned to receive a CAL program with or without tuition/lecture during the study interval: June-September 2009. The main outcome variable was the test scores of English-error identification. To measure the outcomes, the students were evaluated twice using the 25-question test within a 1-month interval (pre-test/post-test). Appropriate sample size estimates, descriptive, uni-, and bivariate statistics were calculated, and the level of statistical significance was set at P<0.05. The sample included 69 students, 36 of whom (52.2%) were in the intervention group (CAL plus teaching). Within-group comparisons showed statistically significant improvements in post-test scores, regardless of learning methods (P<0.05). Tuition/lecture was significantly associated with the improved post-test scores (P=0.0012) and with a higher number of students showing improved post-test scores (P=0.0007). The results of this study suggest that tuition/lecture facilitates self-learning with CAL. In this sample, tuition/lecture still seems to be necessary for nonnative-English-speaking high school students to improve their English proficiency. CAL alone should not be used to replace conventional teaching.
