Developing a Model of a Competency and Students Computer Network International Certification Test for Vocational High Schools

Abstract

This study aims: (1) to investigate the implementation of the available certification test; (2) to find out a model of a competency and students computer network international certification test by integrating a cognitive competency test and a psychomotor competency test; (3) to find out the validity index, the efficiency, and the effectiveness of the model appropriateness; and (4) as well as the effects of the use of the model in the computer network subject on the students' cognitive competencies and interests. This was a research and development (R & D), referring to[2]. The tryout subjects in this study comprised Grade XII students of semester 5 in the computer network study program using the quasi-experimental method. The data were collected through a pretest and a posttest employing the dichotomous model and a Likert-model questionnaire with four scales. The tests of the instrument validity and reliablity referring to the students' cognitive competencies and interests used expert judgement, Pearson correlation, and Cronbach's alpha. The data were analyzed using the descriptive statistics and the t-test. Based on the results of the operational field tryout, it was condluded that: (1) the pretest scores of the experimental class and the control class were sigficantly the same (p >= 0.05); (2) the posttest better pretest scores of the experimental class were significantly the different (p
