The work done when solving linear equations: altering experiences due to change of numbers
Paper i proceeding, 2024
However, as students are used to taking numbers into consideration, the influence of coefficients on equation solving is an important topic to address. In a previous study, a model for how students experience equations was suggested. Here, the model is used to analyse one interview with a student
in upper-secondary school, solving several similar equations but with numbers from varying number domains. The results show the decisive role that numbers play in how this student perceives the equations. Using a wide range of numbers also helped to challenge the student to explore the properties of the equations’ structure. Possible applications in the classroom are discussed.
