Abstract

The objectives of this research were to: 1) study students’ basic Japanese speaking ability before and after using Storyline-based Japanese speaking skill practice packages; 2) examine students’ basic Japanese speaking achievement after using the Storyline-based skill practice packages; and 3) investigate students’ satisfaction with the use of the Storyline-based Japanese speaking skill practice packages. This study was a preliminary experimental research using a one-group experimental design. The target group consisted of 12 Grade 11 students enrolled in the Japanese language program at Kasetsart University Laboratory School, Center for Educational Research and Development, during the second semester of the 2025 academic year. The research instruments were: 1) seven Storyline-based basic Japanese speaking skill practice packages; 2) a basic Japanese speaking achievement test; and 3) a satisfaction questionnaire. The statistics used for data analysis were percentage, mean, standard deviation, relative gain score, one-sample t-test, and dependent samples t-test.

         The research findings revealed that: 1) students’ basic Japanese speaking ability after learning through the skill practice packages was significantly higher than before learning at the .05 level; 2) students’ basic Japanese speaking achievement after using the skill practice packages met the 70 percent criterion with statistical significance at the .05 level, with 11 students passing the criterion, accounting for 91.67 percent; and 3) overall, students’ satisfaction with the skill practice packages was at the highest level (𝑥̄ = 3.63, S.D. = 0.55).
