การพัฒนานวัตกรรมบทเรียนคอมพิวเตอร์ช่วยสอนระบบสื่อประสมเรื่องชีวโมเลกุลด้วยรูปแบบการบูรณาการสำหรับนักเรียนระดับช่วงชั้นที่ 4

Abstract

The main purpose of this research was to develop an effectively innovative Computer Assisted Instruction (CAI) with multimedia system and integrated model on Biomolecules for level 4 students. There were two subsidiary  objectives. These were firstly to compare the learning outcomes before and after the learning experiencewith   he CAI and secondly to compare students who had studied using the CAI lessons with those who had followed  the regular approach with respect to the learning outcomes their experimental skills the creative thinking in science and their attitudes towards learning about Biomolecules. The research was carried out by constructing some ultimedia CAI lessons followed by evaluation before conducting the experimental teaching. Materials and Methods: The CAI software was developed using the program Macromedia Authorware. The lessons were comprised of 3 units (1) Atom and Molecules (2) Biomolecules: [Types Structure Importance and Assembly of Biomolecules] (3) Experiments on Tests of Biomolecules. The CAI lessons were evaluated by experts and achieved  the 80/80 criteria upon try-out. For the phase of experimental teaching. Two classes of students at Suwannaramvithayakom School were randomly selected from the Mathematics - Science streams. In one the experimental group studied using the developed CAI while in the other room the control group studied using the  normal approach. Then the data were collected and statistically analyzed. Results: (1) The CAI on Biomolecules lessons achieved the 80/80 criteria. (2) The post-test average score was significantly higher than the pretest at the level of <0.01 (3) The attitude of the experimental students to CAI was at the level Agreement ( =4.14).  (4) The post-test average score of the experimental group was significantly higher than that of the control group  at the level of <0.01. (5) The experimental group and the control group were not significantly different in their  average   cores with respect to experimental skills and creative thinking. (6) The average score with respect to attitudes to learning about Biomolecules of the experimental group was significantly higher than that of the control group at the level of <0.01. Conclusions: At effective innovative Computer Assisted Instruction (CAI)multimedia system and integrated model about Biomolecules promotes learning by students that is self- directed learning. It can be used as a study tool instead of a conventional lecture: the post-test average scores were better than those of the control group. Moreover the students had a good attitude to learning about biomolecules which are  a basic issue in studying Medicine Science and Biotechnology. Finally this CAI system could easily be developed for teaching  medical and nursing students in the future.
