ABSTRACT

Statistics and Probability has always been one of the most challenging subjects introduced through a spiral approach in the implementation of K-12 Education Curriculum. A stigma that has been apparent long before the COVID-19 Pandemic. But has become more evident for both the learners and teachers during distance learning. The researcher therefore aims to provide an intervention that is applicable even during situations of mandatory implementation of distance learning modalities. Specifically for schools who have no access to online learning modalities. The researcher used Contextualized and Localized Up-to-Date Data Driven Lesson Materials in Statistics and Probability to Grade 11 GAS learners of San Antonio National High School (SANHS) for SY 2022-2023. The materials were developed by the researcher and includes data from the school. Two materials were used in teaching the following competencies: (a) Calculates the mean and the variance of a discrete random variable M11/12SP-IIIb-2; (b) Interprets the mean and the variance of a discrete random variable M11/12SP-IIIb-3; and (c) Solves problems involving mean and variance of probability distributions M11/12SP-IIIb-4. The study also includes presenting how these Contextualized and Localized Up-to-Date Data Driven Lesson Materials have affected the attitudes of the respondents towards Statistics & Probability using the Survey of Attitudes Toward Statistics – 36 (SATS-36) by Schau, 2003. The conduct of this action research therefore aimed to answer the following research questions: (1) What contextualized and localized up-to-date data driven lesson materials can be used in teaching Statistics & Probability for the following Most Essential Competencies: (a) Calculates the mean and the variance of a discrete random variable. M11/12SP-IIIb-2; (b) Interprets the mean and the variance of a discrete random variable. M11/12SP-IIIb-3; (c) Solves problems involving mean and variance of probability distributions. M11/12SP-IIIb-4. (2) What is the attitude towards Statistics & Probability of Grade-11 GAS students before and after using the developed lesson materials? (3) What are the effects of the developed lessons materials on the students’ academic performance on the chosen competencies? Results of the action research conducted from August – October are as follows: (1) two contextualized and localized up-to-date data driven lesson materials were developed in teaching the following competencies: (a) Calculates the mean and the variance of a discrete random variable M11/12SP-IIIb-2; (b) Interprets the mean and the variance of a discrete random variable M11/12SP-IIIb-3; and (c) Solves problems involving mean and variance of probability distributions M11/12SP-IIIb-4. (2) The Grade 11-GAS learners showed improvement towards their attitudes towards statistics and probability. Specifically in terms of affect, cognitive competence, difficulty, interest, and effort. (3) The developed contextualized and localized up- to-date data driven lesson materials have improved the academic performance of the Grade 11- GAS learners. Specifically, with reference to the administered teacher-made pre/post-test, the respondents showed increase in performance level to each of the three competencies. But such increases performance level was not enough for the respondents to achieve mastery level. Hence, the results suggests that there is a need to further improve the developed materials.
