The Application of LADS (Learning Activities of Data Structure Course) Model through the Computer Network System Environment

Abstract

In this paper, we present the application of the Learning Activities of Data Structure Course (LADS) model through the computer network system environment, to examine the learning achievement of students who studied with the developed learning activities, and to analyze the satisfaction of students with the developed learning activities. The research methodology was designed based on the principles of ADDID model as follows: 1) an instructional problem analysis (A), 2) the design (D) of learning units, activities and materials evaluated by the experts, 3) the development (D) of learning units, activities and materials evaluated by the experts, 4) the implementation (I) of the developed learning activities, and 5) documentations on the conclusion and discussion (D). The research instruments were a questionnaire, an achievement test and the learning activities of the LADS model through the computer network environment. The research statistics used were mean, standard deviation, t-test, and the Event1/Event2 (E1/E2) formula for calculating course efficiency. The sample were twenty undergraduate students in the computer education program at Rajabhat Maha Sarakham University. The LADS model through the computer network system environment had been designed and developed through a research process. The developed learning model consisted of seven stages: the previewing of the lesson, the pretest, the self-study, further study, the discussion and conclusion of the learning outcomes, the posttest, and the conclusion of learning activities. The results revealed that the average agreement of the experts regarding the developed learning model was at the high level (Mean = 4.42, and SD. = 0.61). The efficiency value of the learning activities was 80.20/80.05 that higher that the determined value at 80/80. The average pretest score of the students regarding the achievement was at the .05 level. The average level of the students’ satisfaction with the learning activities was high (Mean = 4.23, S.D. = 0.54). The results indicate that the activities of the LADS model through the computer network system environment course are suitable and useful for an instructional purpose.
