The Creation of Instructional Package to Develop Learning Achievement in Musical Signs and Symbols for Grade 7 Students at Mathayom Wat Makutkasat School

Abstract

The objectives of this research are as follows: (1) to create an instructional package on music, with regard to musical signs and symbols, among Secondary Education Grade Seven students at Mathayom Wat Makutkasat School; and (2) to develop learning achievement of on music for Secondary Education Grade Seven students at Mathayom Wat Makutkasat School. The sample consisted of 40 Secondary Education Grade Seven students in the 2021 academic year among Mathayom students at Wat Makutkasat School. The sample was selected using the Cluster Random Sampling technique by drawing one classroom slot. Before teaching, the students had to take pretests. During the teaching period, the researcher taught students by trying the instructional package developed by the researcher. At the end of the study period, the students took posttests. The researcher used the sample scores of classroom exercises and the posttest scores to calculate the learning efficiency on the basis of the 80/80 standard criteria. In addition, the learning progression of the students were studied by comparing the pretest scores with the posttest scores and used the t-test technique. The results of the research revealed that assessing the efficiency of the instructional package regarding musical signs and symbols to develop the learning achievement of Secondary Education Grade Seven students at Mathayom Wat Makutkasat School showed that the instructional package regarding musical signs and symbols had a process efficiency score of E₁ = 89.88, and a result efficiency score of E₂ = 85.13, which were higher than the 80/80 established criteria. In terms of the learning achievement of student development, students had an average and standard deviation of pretest scores ( =12.13, S.D. = 2.15). After learning with the self-developed instructional package, students had an average and standard deviation on the posttest scores ( = 17.03, S.D. = 1.19). After comparing the pretest scores with the posttest scores, the t-test score was equivalent to 90.69. After teaching with the instructional package, the higher learning achievement scores of the student differed at a statistically significant level at.05. The results of this research revealed that the constructed instructional package resulted in teaching and learning efficiency
