Designing a Package to Minimize Errors in Physics Practical Lessons in Nigeria Secondary Schools

摘要

The study focused on the design of an Error Correcting Instructional Packages (ECIP) for secondary school physics practical. The study was designed to validate ECIP as a good instrument to reduce errors in physics practical. A Quasi experimental design of the three group pre-test, pos-test control design was employed. The treatment group was taught using the new package (ECIP), the conventional group was taught with the traditional practical teaching approach while the control group was not treated at all. The sample consisted of 60 physics students selected from different Government Colleges. Two null hypotheses were raised for the study and tested using one-way ANOVA. The study ensured the homogeneity of the three groups. The study confirmed the use of ECIP to be very effective at reducing errors committed by students during physics practical. The drastic reduction in the errors committed after the treatment using ECIP inform the recommendations of the usage of this new package (ECIP) in all secondary schools in Nigeria.
