| Abstract: | The study investigated the effects of participation in the activities of Science-A Process Approach (SAPA) on the oral communication skills of disadvantaged kindergarten children. Experimental-control group, pretest-posttest research design was employed. The investigator designed the Test of Oral Communication Skills (TOCS) to measure students' oral communication skills. Two experimental groups (one morning and one afternoon, N = 52) and two control groups (one morning and one afternoon, N = 48) were randomly assigned from two kindergarten classrooms (morning and afternoon classes in each) in an inner-city school in Columbus, Ohio. The investigator provided the science instruction to all students. Experimental subjects received 22 half-hour lessons from exercises a through k of Part A, SAPA. Control subjects received 22 lessons from Springboards to Science, a teacher demonstration, class discussion type of kindergarten curricuoum used in the school system. The treatment period spanned 12 academic weeks. Analysis of variance of TOCS pretest scores showed no significant differences among any of the means of the four groups. Analysis of covariance of TOCS posttest scores revealed differences significant at .05 or beyond in the mean scores of the experimental groups and control groups for total oral and total receiving skills and for six of the eight subskills measured by TOCS. Application of the Tukey (b) test revealed that experimental group mean scores exceeded control group mean scores in every TOCS skill and subskill area and that in total oral transmitting subskills both experimental group mean scores were significantly greater at .05 level or beyond than corresponding mean scores for both control groups. Within the parameters of this study, it may be concluded that when the activities and teaching strategies of SAPA curriculum are presented to disadvantaged kindergarten children, their oral communication skills, especially the transmitting (speaking) skills, are clearly enhanced. |
