—— This study aimed to determine the Effectiveness of cooperative learning strategies through the use of contextualized lessons plans to the literacy performance of the Grade 5 pupil in English. The findings of the study served as a basis of a proposed intervention plan. This study used the Quasi- Experimental method of research to determine the significant difference of the variables. The researcher utilized Universal Sampling in identifying the respondents of the study. The test of difference between the scores in the post-test of Grade 5 learners for control and experimental group in English after the integration of Cooperative Learning Strategies through the use of Contextualized Lesson Plans in teaching as well as to the continued usage of the traditional approach in teaching to the control group to the different learning competencies in English. Based on the table 4, showing the Grade 5 learners’ performances in the control group for the posttest is said to be much lower compared to the posttest gained by the experimental which resulted to the computed t value which is higher than the critical t value. Based on the given data, the hypothesis which states that there is no significant difference between the post-test performances of the Grade 5 pupils both the control and experimental group in Mathematics after the integration of Cooperative Learning Strategies using Contextualized Lesson Plans is rejected. The results in table 4 implied that that since the results of the control group is having slight increase of the performance on some of the level of performance as shown in the posttest performances of the learners, the traditional way of teaching should not be the focused of the delivery of the competencies. On the other hand, integration of the intervention in delivering the different learning competencies in English for Grade 5 learners which is the Cooperative Learning Strategies using Contextualized Lesson Plans should be continued because it really brought positive changes to the performances of the learners specially in improving their literacy performance. Furthermore, the intervention must be widening its usability which the teachers must utilized this innovation to their different teaching and learning deliveries for them to double check the usability of the intervention.
