Development and Validation of Module in Mathematics I (Fractions) for Secondary Schools
Keywords:
Development, Validation, Module, Mathematics, FractionsAbstract
This study focused on the development and validation of Module in Mathematics, to meet the needs and difficulties of students in High School Mathematics I of St. Mary’s College of Catbalogan, particularly on Fractions. This study used the experimental method using the randomized pretest and posttest control group design. According to Math grade in Grade VI, the computed absolute t-values were 0.396 for the experimental group and 1.270 for the control group. These values proved to be lesser than the tabular value of 2.101 at 0.05 level of significance and df= 18. Thus, the null hypothesis of no significant difference between the posttest mean scores of the experimental and control groups according to Math grade in Grade VI was accepted. There is significant improvement in the performance of the students in the experimental group as shown in their pretest and posttest results. This improvement was brought about by the modular approach of teaching fraction. The modular approach of teaching is more effective than the traditional lecture/discussion method as far as the topic in fraction in mathematics 1 is concerned. It is a fact that the students can go through the module and learn its contents at his own rate, check and repeat same topics of his work if needed, discover process and technique to learn the lesson until the feeling of self-satisfaction is attained. The module is valid in terms of content validity, construct validity and face validity. It is also appropriate and interesting to the first year high school students. The posttest performance of the experimental group and control group did not vary when the subjects were grouped according to sex, age, math grades in grade VI and entrance results. This indicated that the developed module in Mathematics I (fraction) could be used among students regardless of their sex, age, previous Math performances.
