e-Learning 콘텐츠 유형에 따른 학습 효과성 실험 연구 : 농업계 고등학교 ‘식품가공기술 II’ 교과목을 중심으로 = An Experimental Research on the Academic Achievement Test of e-Learning Contents Delivery Types : In the Case of "Food Technology & Engineering II" in Agricultural High School

영문초록 : AbstractAlthough e-Learning has been developed rapidly for the past several years, development and application of agricultural e-Learning contents have been slow in progress as compared with other educational fields. The purposes of the study were to investigate the current status of agricultural e-Learning course management, to develop two different delivery types of e-Learning contents - animation based contents, video based contents - for agricultural high school students, and to examine whether any statistically significant difference in academic achievement is found by each delivery types, face-to-face class, and two types of e-Learning contents.54 students were participated in the experiment and clustered into three groups by the means of completely randomized design which were one control group, two experimental groups. Then, One way ANCOVA was carried out to assess group differences, and the pretest score was set as covariate.The results of the study have been described as follows:First, e-Learning contents dealing with agricultural skills were found still insufficient, meanwhile e-Learning in elementary and secondary education has been rapidly spreaded such as Cyber Home Learning System, EBS e-Learning project, and EDUNET.Second, based on the comparison between pretest and posttest scores, the cognitive change occurred to all students. However, the result of One way ANCOVA showed no significant difference among each treatments. In other words, the delivery types of contents did not influence the academic achievement. Furthermore, it was identified that video based contents were not statistically different from animation based contents in terms of academic achievement. On the basis of the results of this study, several suggestions as follows were proposed:Currently many agricultural high schools have difficulty in providing sufficient laboratory environments to their students. Therefore, there should be more development of various agricultural e-Learning contents to complement current face-to-face lab class.In addition, the results of the experiment indicates that students can acquire statistically similar academic achievement regardless of delivery types of e-Learning contents. Video based contents, however, showed a comparably higher mean score than contents of other groups and those who studied with video based contents showed more active learning attitude as well. Therefore, it is desirable that agricultural e-Learning contents involve video elements to enhance the learning effect.Further, since various synchronous and asynchronous interactive factors which might affect academic achievement were not included in the study, there should be more studies adopting such potential affecting variables as interactive factors and interactions toward academic achievement
