Abstract

This research aimed to develop the international musical note-reading skills of 21 Mathayomsuksa 1 Students at Phon Ngam Phitthayakhan School in the second semester of the academic year 2020, selected through purposive sampling. The learner-centered assessment method was employed and set the criteria of a mean score of at least 70 percent. The research methodology employed Kemmis and McTaggart’s action research spiral within a 4-week intervention. The statistics for data analysis were mean, standard deviation, and percentage.  The research tools were: 1) weekly note forms, 2) teaching schedules, 3) a written test of international musical-note writing and reading, and 4) a score table used as a record of individual students’ reading and writing scores of international musical notes.

The results of this study revealed that students exhibited improvement in the development of reading skills for international musical notes and achieved the defined criteria with a mean score of 72.73 percent. The provision of positive reinforcement through compliments and a considerable amount of time to practice reading skills of international musical notes for at least five weeks encompassing writing international musical notes, singing following the international musical notes, and reciting song lyrics could affect the student’s reading skills for international musical notes, which were higher than the predefined criteria. Therefore, this could be attributed to the student’s prior experience with written international musical notes, which, in turn, fostered an enhancement in their fluency and accuracy in reading international musical notes.
