Development and Validation of Modules on Percent and Ratio for Mathematics I
Keywords:
Development, Validation, Modules, Percent, Ratio, MathematicsAbstract
The advancement of science and technology calls for upgraded mathematics instruction in accordance with standards to improve mathematics achievement of students to meet the demands of our present and modern technology. On the Reading Ease Score and Human Interest Score tests, it was found out that the developed module was fairly easy and appropriate for first year high school students and the module is interesting based on the results of the tests. The level of mathematical knowledge and experience of the experimental and control groups before the experimentation were the same as reflected in their pretest results. If the results of the pretest of the experimental group had been significantly different from the control group or vice versa, the improvement brought about by the method of teaching introduced may not be attributed to it fully but to the one group that is better than the other group at the beginning. There is a highly significant improvement in the performance of the students in the experimental group as reflected in their pretest and posttest results. This improvement was brought about by the modular approach of teaching the topic on percent and ratio. There is a significant improvement in the performance of the students in the control group as reflected in their pretest and posttest results. This improvement in the performance of the students may be attributed to the strategies used by the researcher such as lectures, discussions, seatwork, boardwork, exercises and short quizzes.
