Abstract

The objectives of this research were to 1) develop the quality and efficiency of the instructional package for teaching communication networks and 2) compare the students’ academic achievement from pre-test and post-test scores after using the developed instructional package. The research sample consisted of the 50 first year vocational certificate students of Thanyaburi Technical College studying in Business Computer in the Central Correctional Institution for Young Offenders in the 1^st semester of the academic year 2016 by using cluster random sampling. The achievement test for 30 questions that had the index of consistency (IOC) at 0.67-1.00, the difficulty index (p) at 0.20 - 0.80, the discrimination (r) between 0.20 - 0.40, and the reliability (KR20) at 0.83. Statistics used for data analysis were mean, standard deviation, E₁/E₂ efficiency, and t-test for dependent sample. The result revealed that the quality of the developed instructional package: communication network was at good level in overall ( = 4.43), the quality of content was at very good level ( = 4.74) and the efficiency of media production was at good level ( = 4.20).  2). The efficiency of the instructional package for teaching communication networks was 82.04/81.07 (E₁/E₂) which was higher than the criterion as 80/80 and the students’ academic achievement was higher after using the developed instructional package at statistical significance of .05 level.
