Description

In this study the effectiveness of the CATV system in instructing penmanship by an expert was compared with that of conventional type of lecture by an unskilled teacher. The total of 53 children were selected as subjects from school A and B, 17 and 36 respectively. 36 children of the school B were given the conventional instruction by an unskilled teacher at first. Then, after several days, some of the same subjects were exposed to the TV program for Japanese language of good quality. 17 children of school A were only exposed to the TV instruction. After the instruction every subject was expected to submit his (or her) work to the experimenter. The letters to be written were designated as chinese characters of "誠意". The style of writing was evaluated by three different evaluators according to the several criteria for good writing. The total score for each subject was calculated by using these scores. Three experimental groups, i.e. school B with only conventional instruction, school B with both conventional and TV instructions and school A with only TV instruction, were compared by these scores. Although the scores are slightly different by evaluators, the total score for school A was higher than the other two experimental groups. School B with two kinds of instructions follows and then school B with only conventional instruction. As to the scores by each criterion, the same tendency was obtained and the differences among these groups were significant in most cases. The total standard scores of each evaluator were calculated and analyzed by descriminant analysis. These scores discriminate the three experimental groups. Especially school A was discriminated fairly well with the other two groups. These results show the effectiveness of CATV instruction by a skilled teacher over the conventional instruction by an unskilled classroom teacher.
