This study examines how high school pupils and student teachers tackle equationsthat are presented in various ways. Some presentations are non-standard, forexample having to express -a-usually perceived as a parameter in terms of -x- usually perceived as a variable. We investigate how subjectssolve those equations as well as the differences between pupils and studentteachers.Our findings suggest that equations containing parameters aremore difficult to solve than equations without parameters. The difficultiesare associated with the letters that should be expressed and in the arrangementof the equation. The results of this study may expand the knowledge of teacherson the subject of equations with parameters and on the specific difficultiesencountered by students during the solution process.
