Abstract:
The objectives of this research were 1) to develop and evaluate the efficiency of the electronics book on Physical Features of Asia for Mathayom 1 students at Wat Santitham School, Mueang Nakhon Sawan District, Nakhon Sawan Province, at 80/80 of the criterion, 2) to compare the pretest and posttest of the learning achievement with the electronics book on Physical Features of Asia for Mathayom 1 students, and 3) to study the satisfaction of the students with the electronics book on Physical Features of Asia for Mathayom 1 students. This research applied One Group Pre-test Post-test Design. The sample was 30 Mathayom 1 students in the second room at Wat Santitham School, Mueang Nakhon Sawan District, Nakhon Sawan Province, in the first semester of the academic year 2022, with simple random sampling. The research instruments were 1) the 5 electronics books on Physical Features of Asia, 2) the pretest and posttest of the learning achievement with the electronics book on Physical Features of Asia consisting of 30 items, and 3) the satisfaction test of the students with the learning with the electronics book on Physical Features of Asia consisting of 15 items. The statistics for the data analysis used percentage, mean, standard deviation, and t-test.
The research results were as follows:
1. The result of developing the electronics book on Physical Features of Asia for Mathayom 1 Students had an efficiency of 87.70/86.47, which was higher than the efficiency criterion of 80/80.
2. The result of comparing the pretest and posttest of the learning achievement with the electronics book on Physical Features of Asia for Mathayom 1 students found that the posttest of the learning achievement was higher than the pretest at 0.05 of statistical significance.
3. The result of studying the satisfaction of the students with the electronics book on Physical Features of Asia for Mathayom 1 students found that the satisfaction of the students was at the highest level (x̄= 4.65, S.D.= 0.48).
