Model method: A visual tool to support algebra word problem solving at the primary level

This chapter sets out the research agenda of a series of funded studies with the specific focus to investigate how the model method is used to solve algebra word problems. The Perception study explored how 145 Secondary 2 students perceived the model method and its relationship with letter-symbolic algebra. Algebra 1, Algebra 2, and Algebra 3 are related studies with the second building on the findings of Algebra 1 and Algebra 3 on the first two studies in the series. While all three algebra studies are underpinned by a cognitive-psychological framework, this chapter reports on the pedagogical aspects of the research. Algebra 1 and Algebra 2 worked with Primary 5 students. Both samples answered the same set of algebra word problems. To delineate the knowledge, processes and metacognitive skills necessary to solve algebra word problems, an additional four sets of mathematics tasks were administered to the students participating in Algebra 2. Algebra 3, a 6-year longitudinal study, commencing with students in K2, explores the development of algebraic thinking in students from Kindergarten to Secondary 3.
