APPLICATION OF LABORATORY AND COOPERATIVE FORMS OF PEDAGOGY IN REDUCING STUDENTS' DIFFICULTIES IN TRIGONOMETRY

This is a quasi experimental research designed to determine the application of laboratory and cooperative forms of pedagogy in reducing students’ difficulties in trigonometry in Imo State, Nigeria. The population was made up of 355 SSS2 students in government secondary schools in Ideato South Local Government Area of Imo State, Nigeria. The sample consisted of 57 respondents purposively determined using Diagnostic Mathematic Test (DMT) into Experimental (E), and Control (C) groups which had 27 and 30 students respectively. Respondents in the experimental group were taught Trigonometry using the Laboratory instructional strategy, while those in the control group (C) were taught using Cooperative Learning method. The treatment lasted for 6 weeks. Mathematics Achievement Test (MAT) was administered on the respondents at the end of treatment. Both the DMT and MAT were validated by experts and their reliability assessment using the Pearson Product Moment Correlation Coefficient Formula of r = 0.79 and 0.82 respectively were obtained. Data collected were analyzed using Mean, Standard deviation (SD), t-test, and analysis of covariance (ANCOVA). Results obtained after data analysis showed that there was a significant effect of the Laboratory and Cooperative instructional strategies in reducing students learning difficulties in trigonometry with Laboratory method as a better instructional strategy. Based on these results, it was recommended among others the adoption of Laboratory instructional strategy in teaching trigonometry to improved mathematics achievement among secondary school students.
