The Development of Mathematical Literacy Through Online Learning Inplementation Based on Mathematizing Process in the Topic of Probability for Grade 11 Students

Abstract

          Mathematical literacy is one of necessary competency to apply mathematics to real-life situations. The results of PISA assessment demonstrated that the level of mathematical literacy of Thai students are below the mean score of OECD. This research aimed to study the online learning implementation based on mathematizing process to enhance mathematical literacy, and to develop mathematical literacy through online learning implementation based on mathematizing process in the topic of probability for grade 11 students. The participants were 37 students in grade 11 of a high school in Phetchabun Province in the second semester of 2021 academic year. The research methodology was the action research comprising of 3 cycles and took totally 14 hours. The instruments used in the research were lesson plans, activity sheets, reflective learning journals, and mathematical literacy ability test. Data were analyzed by content analysis and data creditability by triangulation method. The results revealed that 1) The online learning approach through mathematizing process in the topic of probability, the teacher should emphasize on choosing situation in a context relevent to the real world or useful for student, using question lead to problem situations and stimulating questions, reviewing students' fundamental knowledge, giving advice in breakout room immediately and preparing of media and programs for the online learning implementation. 2) Most students developed mathematical literacy in 3 processes, the students had the greatest improvement in thinking/transforming situations in mathematical problems, followed by the use of mathematical principles and processes to solve problems and interpreting and evaluating the results, respectively.
