Does representation matter? Teacher-provided tables and drawings as cognitive tools for solving non-routine word problems in primary school
Journal Title: European Journal of Science and Mathematics Education - Year 2018, Vol 0, Issue 0
Abstract
According to the German educational standards, students should be familiar with problem-solving as a general mathematical competency by the end of grade 4. Non-routine word problems are suitable tasks for mathematical problem-solving in elementary mathematics classes. They are characterized by the fact that the problem-solver cannot simply use well-trained algorithmic calculating procedures (Rasch, 2001). As a result, many students struggle with word problems in mathematics, especially with non-routine word problems (Hohn, 2012). Representation plays a central role in the process of problem-solving. It involves representing a problem situation adequately, constructing a mental model and comparing it in a dynamic and iterative process with the information externalized in the representation (Schnotz et al, 2011). This study aims to shed light on teacher-provided representations as cognitive tools for students when working on non-routine word problems. In an experimental study, we examined a sample of 67 primary school students who worked on six non-routine word problems with provided representations. The tasks were accompanied by a table or a drawing. Furthermore, the tables and drawings differed with regard to the amount of information provided. Statistical data analysis generated, among other findings, two results: Overall solution rates were low (10 to 24%). Tables and drawings facilitated the solution process differently depending on the type of word problem. Consequences for subsequent future research are discussed.

Polya and GeoGebra : A dynamic approach to problem solving
Problem solving has been investigated in mathematics education for more than 60 years ago with the pioneering work of George Polya ( Polya , 1965). The four steps he proposes : understand the problem , devise a plan , ca...

The role physics can play in a multi-disciplinary curriculum for non-physics scientists and engineers
At many physics departments a significant fraction of teaching is in support of engineers and scientists in other majors. These service courses are thus an automatic crucible of interdisciplinary interaction, and at time...
