EFFECTIVENESS OF COMPUTER TUTORIAL MODEL, DRILL AND PRACTICE ON STUDENTS’ ACHIEVEMENT AND RETENTION IN FABRICATION AND WELDING TECHNOLOGY IN TECHNICAL COLLEGES

Abstract

The study determined the effectiveness of computer tutorial model, drill and practice on students’ achievement and retention of students of fabrication and welding technology in technical colleges in Delta State. Two research questions were answered, and two null hypotheses were tested at 0.05 level of significance. Quasi-experimental design was used for the study. Population of the study was 136 National Technical Certificate (NTC) year 2 fabrication and welding students in state owned technical colleges. Purposive sampling technique was used to draw four schools out of the six technical colleges with 101 students for the study. Instruments for data collection were Fabrication and Welding Achievement Test (FWAT). The instrument was face and content validated by three experts. Test–retest method was used to establish its reliability of FWAT and was calculated using Pearson product moment correlation which yielded a correlation coefficient value of 0.87. Treatment procedure of computer tutorial model, drill and practice instructional strategy and Lecture-demonstration teaching method for the study was carried out. Arithmetic mean and standard deviation were used to answer the research questions while Analysis of Covariance (ANCOVA) was used to test the null hypotheses. The students in the experimental group obtained higher mean scores than in the control group in cognitive achievement as well as in cognitive and psychomotor retention. There was a significant difference between the mean scores of experimental group and control group in the cognitive achievement and psychomotor retention of students in fabrication and welding in technical college. In view of the positive effects of computer tutorial, drill and practice it was recommended among others, that the method should be adopted to teaching fabrication and welding technology in order to enhance students’ cognitive achievement and psychomotor retention. Also, the school administration should provide opportunities for in-service training and provide computers for fabrication and welding technology teachers and students to enable them acquire competencies needed in the use of modern technology instructional approach for teaching and learning fabrication and welding in technical colleges.
