Developing and Contextualizing Instructional Materials in Mathematics for Grade 6 Pupils

This study used the descriptive developmental method utilizing the contextualized instructional materials. Respondents were composed of the school principals, master teachers and mathematics teachers who have been considered as experts in the scrutiny and critiquing of the instructional materials, grade 6 pupils who benefitted the developed instructional material were also included as respondents. The data were analyzed using frequency counts, percentage, mean, ranking a weighted mean. T-test was utilized to test the null hypothesis if there is a significant difference between the pre-test and posttest results of the pupils. The research instrument is a survey questionnaire. The assessment of the respondents were based on the different variables mentioned for the evaluation of an effective instructional materials. A five-point Likert’ Scale was used to indicate the assessment, these are: Very Acceptable (5), Acceptable (4), Moderately Acceptable (3), Less Acceptable (2), and Not acceptable (1). It can be depicted the variables included in the instructional material had an overall computed mean value of 4.20 and rated as very acceptable. This study found out that there is a significant difference of the pupils’ pretest and posttest after using the developed instructional materials. The result depicted that the computed t-value of 28.98 with the degrees of freedom of 49 is greater than the critical value of 1.645 at 0.05 level of significance which means there is a significant difference between the pre-test and post-test mean score of the pupils.
