Thinking of Optimizing the Role of Mental Imagery through PjBL for Mathematically Literate Life: Systematic Literature Review

Abstract

The demands of literate life are increasingly crucial in this era, because being literate means being able to deal with real problems in life using certain scientific concepts, including mathematics concepts. Meanwhile, humans are capable of 'creating', 'ideas' and 'doing' according to what is 'imagined' in their minds. As Rene des Cartes said: Cogito Ergo Sum. So, one of the main aspects is the role of mental imagery for each individual. This article discusses theoretically the role of mental imagery through Project-based Learning to build mathematical literacy. Articles are built with a systematic literature review. It was concluded that mental imagery plays an important role in building mathematical models, presenting aspects of the problem in the form of meaningful mathematical illustrations. Conversely, mental imagery also plays an important role in translating mathematical concepts into ideas and concrete forms in the context of life. Both of these are very suitable to run in project-based learning. Because the project leads students to develop ideas and be creative according to their imagery.
