Improving Least Mastered Mathematical Skills among Tertiary Education Students in Mathematics in the Modern World through Strategic Intervention Materials

This study aims to develop a SIM (Strategic Intervention Material) using problem-based learning or approach in improving least mastered mathematical skills of tertiary education students in Mathematics in the Modern World. This study also aims to prove that using SIM in teaching is more effective than the traditional way of teaching. This study made use of True Experimental Design. A total of 95 students of Camarines Sur Polytechnic Colleges who were enrolled in Mathematics in the Modern World served as the respondents of the study. Percentage, mean and t-tests were used as tools in the Analysis of data. T-test for Dependent Samples was used to determine the significant difference between the pre-test and post-test results of the students in Logic. T-Test for Independent Samples was used to determine the significant difference between the post-test results of the two-group of respondents in Logic. It was found out that there was a significant difference between the pre-test and post test results of the students in Logic. Also, there was a significant difference between the post-test results of the two groups of respondents in Logic. After using SIM to teach the lesson, it can be concluded that the experimental group's students performed significantly better. Thus, it was better and more effective to teach using SIM. It was also suggested that SIM be used as an instructional material or strategy for teaching Mathematics in the Modern World.
