A Comparative Study of Touch-Typing Skill, from CAI with 3S (Sight-Sound-Speech) Systems\, between Mechanical Electrical and Civil Students in the Faculty of Technical Education KMUTNB

Boonsa Prasertsawat, Manit Sittichai


The purposes of this study were to 1) develop a computer-assisted instruction on Sight-Sound and Speech System for touch-typing skill practice of English and Thai languages, to 2) validate the efficiency of the CAI, to 3) compare the mean scores of the tough-typing skill before and after training of both languages, to 4) compare the touch-typing skill mean score of Mechanical Electrical and Civil Students, to 5) compare the skill durability between Mechanical, Electrical and Civil Students, to 6) analyze the correlation of the scores obtained from the scholastic aptitude test and the touch-typing skill test for English and Thai languages. The research design was one group pre and post test. The sample was used 21 voluntary freshmen, each of 7 students from the Mechanical, Electrical and Civil Engineering Departments, Faculty of Technical Education, King Mongkut’s University of Technology North Bangkok. The instruments were used a computer-assisted instruction package on 3S touch-typing practice of English and Thai languages, pre and post tests and a scholastic aptitude test. To develop the CAI package, the frequency of alphabets and words used in the 15 outstanding theses in the 3 fields of Engineering was counted. Alphabets were counted by the Character Frequency Analyzer software, using Xampp Control Panel so that the lessons and the exercise after each lesson could be provided. The lessons were arranged from the most to least frequent alphabets appeared. Macromedia Flash, Sound Recorder, Cool Edit 2000 and Adobe Audition. The research results were as follows. 1) There were 13 Thai typing lessons and 10 English typing lessons in the constructed CAI package and the time spent on typing practice was one hour per lesson. 2) The efficiency of CAI was 89.66/93.75 for Thai and 87.53/90.95 for English lessons. 3) The mean scores of both Thai and English languages gained from the post-test were higher than the pre-test with the significant level of .01. 4) The mean scores comparison of Mechanical, Electrical and Civil students was significantly different in terms of both languages and the gained typing skills for Thai and English were 18.75 and 22.74 Gross Word a Minute. 5) The decreasing of the touch-typing skills after the end of training 2 weeks signified that the skills decreased 2.02 % for Thai and 1.26 % for English language which were significantly different at the level of .05. 6) The correlation between the scores obtained from the scholastic aptitude test and from the touch-typing skill test, was 0.62 for the Thai language and 0.58 for the English language.
