Mediated Instruction and Redundancy Remediation in Sciences in Secondary Schools in Uyo Urban

P J Etim, I N Udosen, G O Ofili


The study was on Mediated Instruction and Redundancy Remediation in sciences in secondary schools in Uyo urban. Two hypotheses were postulated. Quasi-experimental design was adopted for the study with a total of 200 students purposively sampled from two secondary schools. 50 students each were used as experimental and control groups in the two schools selected. A computer designed instruction on circulatory system developed on power point projection was used in treating the experimental group, while the expository pedagogical strategy was used to teach the control groups on the same lesson. Redundancy remediation achievement test (RRAT) was developed to test the ability levels of students in both the experimental and control groups. The RRAT‟ had a reliability coefficient of .85. The data were analyzed using t-test statistics. Data analysis revealed that use of mediated instruction significantly removed redundancy for science students also the use of mediated instruction influenced academic achievement of science students in secondary schools. Some of the recommendations include that science teachers should be trained to use ICT facilities in order to integrate it into the teaching learning situation and also that Internet facilities should be provided in all schools to ensure its utilization by both science teachers and students.
