Abstract:
The purpose of this study was to compare the effects of teaching restatement skills through three different teaching strategies, i.c. through lecturing modeling and role-playing. The sample included 33 counselor students, selected at random from the 50 third year undergraduate students registered for the course Psychological Testing (417-313) during the first semester of 1981, at the Faculty of Education, Chulalongkorn University. These subjects were randomly assigned to 3 groups of 11 students each. Each group was exposed to one of the different teaching strategies: lecturing, modeling and role playing. Data were analyzed according to the split-plot design. Independent variables included the three teaching strategies and the number of times each strategy was used. The dependent variable was achievement scores on a test to measure learning and skills about restatement skills. The following hypotheses were tested: (1) the 3 different strategies of teaching produce different levels of achievement about restatement skills (2) there is a difference in the level of achievement between the subjects who were exposed to a particular strategy only once and those who were exposed to it twice. The instruments used inclued a lecturing lesson plan, a videotape for presenting models, scripts for role-playing and achievement tests. The data were analyzed through the computation of the two-factor analysis of variance repeated measure on one factor and the multiple comparison by the T-method of Tukey. Findings supported both hypotheses at the .01 level of significance. Further analysis showed that role-playing produced the highest level of achievement, followed by modeling and lecturing. Achievement after having been taught twice was higher than after of one time for all teaching strategies at the .01 level.
