  • Conference paper (peer-reviewed)abstract
    • This article identifies knowledge components needed for successfully solving linear equations. Data for this purpose is 359 Swedish year 9 students’ written responses to the test task ”solve the equation 2x + 3 = 11”. The following set of knowledge components were identified; arithmetic knowledge, parsing knowledge, balancing equations, giving a value to the unknown, not omitting parts and the habit of verifying the solution. This paper discusses for which of these knowledge components, students could discover and correct their own errors if they would both solve an equation and verify its solution.
