Abstract:
The purposes of this research were 1) to develop and test the efficiency of an instructional package on an intelligence control for teaching by with traditional method, 2) to develop and test the efficiency of an instructional package on an intelligence control for teaching by Case-based learning(CBL) method, 3) to compare learning achievement of learner between learning by CBL and learning by traditional method, 4) to compare learning achievement of learners between before and after learning by CBL method, and 4) to study the satisfaction of learner who learn by CBL method.
The research process was divided into two parts: 1) development of an instructional package on an intelligence control with traditional method, 2) development of an instructional package on an intelligence control with CBL method which were the preparation of teacher and learner, presentation of case study (P), analysis of case (A) study, case study (S), discussion (D), supplementing (S), conclusion (C), and evaluation (E) or called PPASDSCE Model. After that, try-out with the sample group of 48 graduate students at department of teacher training in electrical engineering, faculty of technical education, King Mongkuts University of Technology North Bangkok, who had enrolled class related with automatic control in the first semester of 2013. The sample group was divided into two groups, an experimental group (Learning by CBL) and the control group (Learning by traditional). The experimental group was 24 second year electrical students and the control group was 24 third year electrical students. The period of experiment was 5 weeks. The tools used in this research were the instructional package (CBL and traditional method), the demonstration (ball and beam, ship stabilizer, air flow and water pump), an observation form the behavior of learner, the self-evaluation and group member form, and satisfaction survey. The standard deviation, average, and t-test dependent and independent were used in this research.
The research results were as follows: 1) the efficiency of the instructional package on an intelligence control for teaching by traditional method was 76.30/73.32 less than the expected standard because of the basis of the learner, difficulty of the content and volume, and too little time. 2) The efficiency of the instructional package on an intelligence control for teaching by case study method was 64.84/62.90 which was less than the expected standard because of expertise in using the instruction set of the instructor, basic knowledge of learners, difficulty of the content and volume, too little time, availability of the learners, unacquainted with the learning styles of the learner, and difficulty of the study case. 3) The learning achievement between who used case study method was less than students who used traditional method at .05 significantly because of the different workload, the different basic knowledge, the different expertise to teach, and different learning styles. 4) The comparison between pre-test and post-test scores reported statistic significant difference at .05 with the post-test scores were higher than the pre-test scores. 5) The learner who learned from the case study method satisfied at high level.
