The Development of Audio Equipment Competency Training Board SMP 88-96, Audio Equipment Course, code of 20105-2008

Abstract

The objectives of this research are 1) to create and find out the efficiency of the audio equipment competency training set, SMP Board 88-96. 2) to study the learning progress of students who study with the audio equipment competency training set, SMP Board 88-96. 3) To study the satisfaction of students learning with the audio equipment competency training set, SMP 88-96 board. used for teaching the audio equipment subject. Course code 20105-2008, Vocational Certificate level (Vocational Certificate), 2nd year, Electronics Technician field. Nakhon Nayok Technical College, Semester 2, academic year 2021, to have efficiency according to the standard criteria 80/80. Comparison of academic results before and after studying. From a sample of 31 people, divided into 2 groups: an experimental group of 14 people and a control group of 17 people using a simple random sampling method. Expand the results and reuse the machine performance training set. Voice of SMP Board 88-96 in the 2nd semester of academic year 2022, number of 53 people and the second semester of academic year 2023, number of 23 people.
The tools used in the research include the academic achievement test. and satisfaction level questionnaire Data were analyzed for percentage (Percentage), mean (Mean), standard deviation (Standard Deviation) and test statistics (t-test). The results found that The results of the analysis of the level of opinions of experts on the sound system performance training set, SMP 88-91 board, have
a value ( 𝑥̅ = 4.64,S.D.= 0.58 ), which can be interpreted as being in the highest criteria. And there is
a sound system performance training set. The SMP 92-96 board has a value ( 𝑥̅ = 4.68,S.D.= 0.49 ), which means the results are within the highest criteria. Work efficiency test results Met the requirements
by 100 percent. Academic achievement before and after studying of students in the experimental group. After studying higher than before studying Significant at the 0.05 level and the results of the learning process during study and the achievement measurement after study were set at 80/80 with a value of 82.42/81.90 found to be in accordance with the specified criteria. Students who passed the competency test were 100 percent. The results of the evaluation of the satisfaction level of students who studied with the audio equipment competency training set, SMP 88-91 board, had a value ( 𝑥̅ = 4.71,S.D.= 0.47 ) can be interpreted that the results are within the highest criteria. And the sound system performance training set, SMP 92-96 board, has a value ( 𝑥̅ = 4.74,S.D.= 0.46 ), which can be interpreted as being within the highest criteria.
