    Pre-service Mathematics Teachers' Professional SelfEsteem and Beliefs about the Nature of Mathematics
    (2021) Akdeniz, Dilşad Güven; Gürefe, Nejla
    This study aims to examine the professional self-esteem of pre-service primary school mathematics teachers in the context of their beliefs about the nature of mathematics. The study has a quantitative design and 220 pre-service mathematics teachers voluntarily participated in the study. In the data analysis of this study based on a quantitative research design, independent samples t-test, one-way ANOVA and multiple regression analyzes were performed and the Pearson correlation coefficient was determined. According to the findings of the study, professional self-esteem and belief about the mathematics' nature are not affected by gender and grade level. In addition, professional self-esteem of the pre-service teachers who believe that mathematics is a branch of science open to exploration, knowledge generation, and related to other sciences and daily life, may be said to be higherpositive than the professional self-esteem of the pre-service mathematics teachers who perceive mathematics as a set of unrelated concepts and formulas or believe that mathematics is a deductive and precise body of knowledge.

    The Knowledge of Middle Level Math Teachers Regarding Inclusive Students’ Misconceptions About the Concept of Angle
    (Routledge, 2024) Gürefe, Nejla; Güven Akdeniz, Dilşad
    The authors examined the knowledge of middle level mathematics teachers instructing in inclusive classrooms to the hearing impairments students (HISs) or learning disabilities students (LDSs). The focus was on teachers’ understanding of students’ misconceptions related to the concept of angles. The study aimed to investigate the teachers’ role in identifying the underlying perceptions of misconceptions among HISs and LDSs as well as their ability to offer effective solutions. The mathematics teachers responsible for HISs and LDSs were the subjects of this cross-case study, with the unit of analysis being teachers’ knowledge of misconceptions concerning the concept of angles. Face-to-face interviews were employed to collect data, and subsequent analysis utilized a cross-case approach. The study findings revealed that both groups of teachers encountered numerous misconceptions for the first time. While teachers of HIS (HIST) identified the source of misconceptions as either teachers or students, teachers of LDS (LDST) more frequently attributed misconceptions to teachers and employed various representations to address and dispel these misconceptions. The authors recommended that teachers develop deep understanding of their students and identify potential misconceptions and that they explore diverse methods for taking precautions to prevent misconceptions. © 2024 Association of Middle Level Education.
