Development of E-books on Software and Computer Networks Career and Technology Learning Subject Group For students in grade 2

Abstract

The objectives of this research were 1) to develop e-books on software and computer networks 2) to study the effectiveness index of e-books on software and computer networks 3) to compare students' learning achievements before and after learning with books. 4) To study the attitudes of Mathayom Suksa 2 students towards teaching and learning activities in computer subjects. The sample group consisted of 32 students in Mathayomsuksa 2/1, Nong Haen Pattana Wittayakom School, semester 2 of Academic Year 2018, totaling 32 people who were obtained by using Cluster Random Sampling. E-book on software and computer networks Career and Technology Learning Subject Group Mattayomsuksa 2, 18 subjects, learning management plans, software and computer networks Career and Technology Learning Subject Group Secondary School Year 2, 18 plans, 30-item achievement test, a four-choice multiple choice, with a difficulty (P) ranging from 0.37 to 0.75, and a power of discrimination (B) from 0.30 to 0.75. 0.77 and having a confidence value of 0.82 and the attitude scale of Mathayom Suksa 2 students towards teaching and learning activities in computer subjects was a 5-level estimation scale of 20 items. The statistics used in the data analysis were as follows: Percentage Mean Standard Deviation and t-test statistics. Conclusions of the study 1. The efficiency of the electronic book titled Software Selection Unit 1 Software Selection Efficiency (E1/E2) is equal to 85.43/83.43 Unit 2 Computer network data communication efficiency (E1/E2) is equal to 84.32/82.29 Unit 3 Internet and usage efficiency (E1/E2) is equal to 85.94/82.50 and overall efficiency of e-books on software and computer networks Career and Technology Learning Subject Group Secondary School Year 2 (E1/E2) was equal to 85.23/82.75, which was higher than the specified criteria. 2. Effectiveness of electronic books on software and computer networks. Career and Technology Learning Subject Group Secondary School Year 2 was equal to 0.6749, meaning that students had an increase in learning achievement. After learning by using e-books on software and computer networks. Career and Technology Learning Subject Group Secondary School Year 2 accounted for 67.493 percent. Career and Technology Learning Subject Group Secondary school grade 2 before and after learning by using electronic books on software and computer networks. Career and Technology Learning Subject Group Secondary school grade 2 found that the achievement after school It was higher than before with statistical significance at the .05 level. 4. The results of the study of the attitudes of Mathayom Suksa 2 students towards teaching and learning activities in computer subjects found that the overall standard deviation was 0.41. and the mean is 4.75, which is the highest level.
