The Development of the Electronics Book Titled “The Use of Multimeter in the Measurement of Electrical Quantities in Direct Electrical Circuits”

Abstract

The objectives of this research were to develop the electronics book titled “The Use of Multimeter in the
Measurement of Electrical Quantities in Direct Electrical Circuits” and to evaluate its quality. The targeted
subjects of the study were 108 first-year students from the College of Medicine who registered in the course “Life Science Physics” during the second semester of the academic year 2014. The instruments of this study were the electronics book titled “The Use of Multimeter in the Measurement of Electrical Quantities in Direct Electrical Circuits,” and the form for evaluating the quality of the e-book in 5-point scales. The evaluation form in the form of a questionnaire consisted of three main areas: contents, designs, and application. The topics of contents included six subtopics; the topics of designs had five subtopics; and the topics of application were with four subtopics. The reliability of the questionnaires was 0.892. Descriptive statistics such as percentage, mean scores, and standard deviation were used to analyze the data. The research findings were as follows:
1. The e-book titled “The Use of Multimeter in the Measurement of Electrical Quantities in Direct Electrical Circuits” consisted of a front cover, a preface, a table of contents, and contents in a total of 42 pages. There were a total of 27 files of mp3 (sound files) and mp4 (video files).
2. The mean scores of the evaluation of the quality of the e-book titled “The Use of Multimeter in the Measurement of Electrical Quantities in Direct Electrical Circuits” were the highest in the area of contents on the topic of the constructional contents which covered all learning objectives ( x  4.22 ); the highest in the area of designs on the topic of forms of letters and font sizes ( x  4.19); and the highest in the area of applications on the topic of “Medias for self-directed learning” ( x  4.09), which was at a good level.
