ABSTRACT tb., This document presents a first approximation for a model for student performance in solving linear equations. First, characteristics of a model of student performance for solving linear equations is discussed. It is noted that there is a need for some theoretical structure to support and organize the bits and pieces of information provided by available research. Next, known research on student performance for solving linear equations is surveyed. The material goes on to discuss modeling performance. A student performance model is presented, and research questions are suggested. The suggested questions are viewed to be ones that need to be addressed in order to elucidate the relevance of the model presented. A hope is expressed that future research will be part of a deeper study and analysis of student performance in solving linear equations. A thorough understanding of performance is seen as a possible aid to pupil improvement in algebra competencies.
