INFUSION OF POLYA AND DIGITAL BAR MODEL: AN ALGEBRAIC THINKING MODULE FOR SEVENTH GRADERS

Algebraic Thinking Skills (ATS) are one of the skills that students need to master in order solve non-routine problems. These also necessary as a foundation for preparing enter university studies and fields work require logical analytical thinking. However, Malaysian students' performance solving algebraic problems still needs be satisfactory, according TIMSS 2019 PISA 2018 reports. Therefore, Module (ATSM) was developed cultivate ATS through three constructs, namely i) arithmetic generalization, ii) functions, iii) modelling. The ATSM using heuristic method by infusing Polya digital bars model. bar model illustrates rectangle representing known unknown quantities relationship between quantities. refers free application at https://mathsbot.com/manipulatives/bar. An test administered pre-and post-test on 120 seventh graders from rural schools Sabah. paired sample t-test results showed significant difference mean scores pre-test after intervention ATSM. This shows can improve infusion is able help shape thinkers digitally savvy students. Keywords: thinking skills, model, problem solving,
