Özet:

The aim of this study is to investigate the experimental abstraction processes of 7th grade students in relation to the variables of attitude, anxiety, self-efficacy and motivation towards mathematics. This is a mixed method correlational study using a sequential explanatory design with two distinct stages. The study group consist of 91 students attending public schools in Ordu city center who were selected by using criterion sampling technique. The data collection tools used in the study are Abstraction Test (AT) which was developed by the researchers and consisting of 8 open ended, gap filling and multiple choice questions, Clinical Interview Processes conducted with the students, Mathematics Attitude Scale developed by Duatepe and Çilesiz (1999), Math Anxiety Scale developed by Erol (1989), Mathematical Self-Efficacy Scale developed by Umay (2001) and Mathematics Motivation Scale developed by Githua and Mwangi (2003)- adapted to Turkish by Ayan (2014). In the analysis of the qualitative data obtained from the study, Action Sequence formed by the researchers and the Clinical Interviews conducted with students were used while Pearson-Correlation analysis techniques were used for the analysis of the quantitative data of the study. As a result of the study, it was seen that students generally do not perform well in the process of knowledge construction and they have misconceptions about the concept of slope. In addition, a significant positive relationship was found between students' knowledge construction processes and attitude-self-efficacy scores towards mathematics, while a significant negative relationship was found between knowledge construction processes and anxiety levels. In the light of the results obtained from the study, some suggestions were made for the literature and teaching environments.
