Development and Validation of Module on Exponents and Radicals in Mathematics III

The main problem of the study is to develop and validate modules in high school Mathematics III based on the difficulties encountered by third year students of La Milagrosa Academy, Calbayog City, during the school year 1995-1996. The computed t-value in module 1 is 3.15 and 3.14 in module 2 were very much greater than the tabular t-value of 2.064 at 0.05 level of significance and 48 degree of freedom, indicating the rejection of number 5 null hypothesis. The rejection of the null hypothesis shows that there is a significant difference between the retention of the control group and the experimental group. This finding shows that the experimental group whose members were taught using the modularized instruction has better retention than the control group which was taught using the lecture-discussion method. In the light of the finding of this study, the following conclusions were drawn. The modular approach of teaching is more effective than the lecture-discussion method in so far as the sub-topics exponents and radicals are concerned. The fact is that students can go through the module even outside the classroom, they can repeat some sections of the work if needed, discover the lessons by themselves and progress at his own rate until the feeling of self satisfaction and accomplishment are attained. The modules are appropriate and interesting to the third year high school students in terms of readability level. Students in the experimental group who were taught using the modularized instruction have better retention than the students in the control group who were taught using the lecture discussion method.
