The main goal of this study was to examine the relationship of components and features of mother tongue activity sheets to student’s cognitive competency and performance. This particularly would like to determine the level of validity of components of mother tongue activity sheets; features of learner’s cognitive competencies in terms of remembering, understanding, and applying and performance. Moreover, this research would like to test the relationship of components and features of mother tongue activity sheets and student’s cognitive competencies and students performance in terms of practical test. This study used an experimental method in collecting and gathering data based on the mother tongue evaluation of the respondents. To gather data, the researcher utilized a researcher-designed questionnaire that served as the primary tool and used statistical analyses including mean, standard deviation, frequency, percentage, and Pearson correlation coefficient to assess hypotheses. From the analysis of data of the research, It is evident the respondents are strongly agree about the level of validity of component of mother tongue activity sheets, features of mother tongue activity sheets and their level of cognitive competencies. Furthermore, students were outstanding among the folk-dance presentations as part of the assessment in physical education. There is significant relationship between components of features of mother tongue activity sheets and learner’s cognitive competencies, while there is no significant relationship in practical test. Based on the findings the study, it can be concluded that the components and features of mother tongue activity sheets upon utilization in the physical education showed significant importance on developing students cognitive competency. This mean that cognitive development in physical education subject were influence by the components and features of mother tongue activity sheets as it supported the students understanding of concept with activities, task and content and processed the mastery of competencies., Meanwhile, the components and features of mother tongue activity sheets upon utilization in the physical education showed as not major determinant on developing students' performance in practical examinations. The students have different level of execution based their level of understanding and capacity to perform as well as their learning style. Therefore, the hypothesis stated were rejected and accepted in terms of practical test. Based on the findings and conclusions made, it is recommended that school may utilize the activity sheets aligned to the step-by-step procedure of lesson delivery with complete components to address student’s difficulty and conduct learning action cell in designing activity sheets with complete components and features that includes activities to address students' cognitive competencies. Also, the physical education teachers may use mother tongue-based instruction in presenting steps in performing specific dance among learners to attain mastery. for the future study further investigation on the implementation practices and teacher’s preparation in creating mother tongue based instructional materials were recommended.
