EFFECT OF DEMONSTRATION TECHNIQUE ON ACHIEVEMENT OF STUDENTS IN KEYBOARDING IN POLYTECHNICS IN NASARAWA STATE
This study determined the effect of demonstration technique on achievement of students in keyboarding in polytechnics. The study used four research questions and four null hypotheses. The study adopted a quasi-experimental design, specifically non-equivalent control group design. The study was carried out in two polytechnics in Nasarawa State: Nasarawa State Polytechnic, Lafia and Federal Polytechnic, Nasarawa. The control and treatment groups were taken from each of the polytechnics. The treatment group was taught using demonstration method lesson plan for their learning. The control group was taught using lecture method lesson plan, for their learning, which did not require demonstration technique application. The data used for the study was collected using a Keyboarding Achievement Test (KAT). The KAT was face-validated by experts in education. The reliability coefficient of 0.56 was obtained for the KAT. Mean was used to answer research questions, while ANCOVA was used to test the hypotheses at P < 0.05. From the result obtained, it was found that students in the treatment group had a higher achievement level than those in the control group, and significantly too. In addition, male students had a significantly higher achievement level in keyboarding than female students in the treatment group when using lecture method and demonstration technique. The ability level of students which can bep high or low had a significantly effect in keyboarding. Based on the findings, it was recommended that keyboarding lecturers in polytechnics should adopt demonstration technique for instructional purposes. Polytechnic administrators should support and mobilize funds needed to provide facilities that are for use in keyboarding instruction class. Ministries, Departments and Agencies that oversee education matters of polytechnics should improve the funding in their budget for provision of training and learning facilities in the polytechnics. Curriculum experts in the Nigerian Educational Research and Development Council should review the Secretarial studies curriculum for polytechnics to include teaching techniques for instruction.
