บทคัดย่อ

This article investigates whether Concept Attainment Model (CAM) can help Mathayom 1 students of different proficiency levels learn active and passive voices in the simple past tense. The effectiveness of learning grammar through the CAM was examined. In this study, the participants were 26 Mathayom 1 students at Hua Qiao Ubon Ratchathani 2, Ubon Ratchathani. They were divided into three proficiency groups: high, intermediate and low. There were 10, 4 and 12 participants in each group, respectively. The pre-test was administered to the participants in the first period. The following periods were for the treatment which the exemplars were presented to the participants to study in order to specify the concepts. The last period, the participants took the post-test which the scores were used to compare to those of the pre-test using t-test and ANOVA. The results revealed that although CAM did not help the intermediate group learn the passive voice, it could overall help students of different proficiency levels learn active and passive voices in the simple past tense. It was most helpful for the high proficiency level students. CAM is, therefore, a suitable teaching tool for all proficiency levels students, especially the high group.
