    Self-Reflection Processes of the Novice Middle School Mathematics Teachers *
    (Turkish Education Assoc, 2022) Bozkurt, Erhan; Yildiz, Pinar; Gurel, Ramazan; Ozdemir, Iffet Elif Yetkin
    In this case study the aim is to examine the self-reflection processes (self-evaluation, causal attribution, emotional reactions and inferences) of novice mathematics teachers. The participants were six middle school (grades of 5-8) mathematics teachers who have less than five years teaching experience working in the Western and Central Anatolia Regions of Turkey. The data of the study were collected through the semi-structured interviews developed based on classroom observations. First, the instructional situations were determined by observing the mathematics lessons of the participants (approximately 10 hours for each participant). Afterwards, through semi-structured interviews, the participants were asked to reflect on these instructional situations. During the data analysis, first within case analyses were made, and the self-reflection of each teacher was described. Then by comparing the data obtained from six teachers, it was defined which self-reflection processes the novice mathematics teachers performed and to what extent they performed them. The findings suggest that the participants did not consider their teaching behaviors when they were asked to evaluate the lesson. They attributed the cause of the failure in their lessons to factors beyond their control (e.g., low involvement of parents, insufficient physical facilities of the school). In addition, it is observed that they were less likely to develop positive emotional responses for the observed lessons and were insufficient in taking adaptive decisions for their future lessons. These findings indicate the necessity of pre-service and in -service practices that will support newly recruited middle school mathematics teachers to gain much more comprehensive self-reflection skills.

    The Effect of Self-Confidence on Mathematics Achievement: The Meta-Analysis of Trends in International Mathematics and Science Study (TIMSS)
    (Gate Assoc Teaching & Education-Gate, Switzerland, 2019) Ciftci, S. Koza; Yildiz, Pinar
    The aim of this study is to examine the effect of self-confidence on mathematics achievement. In this meta-analysis, the effect of self-confidence on mathematics achievement was analysed using the Trends in International Mathematics and Science Study (TIMSS). In the first stage of the study, the average effect size of self-confidence on mathematics achievement was determined, and in the second stage, the moderators that may impact average effect size were investigated. For the meta-analysis, 336 independent data belonging to 76 countries included in the TIMSS (2003, 2007, 2011 and 2015) were combined, and a sample of 1,028,567 subjects was obtained. The average effect size was then calculated using the differences between means (Cohen d) based on the random effect model, whereas the significance of the moderator variables was calculated using the Q statistic. The results indicated that self-confidence has a moderate effect on mathematics achievement. In addition, the year in which the survey was conducted, national culture, continent of the country and Human Development Index were found to play a moderator role in the effect of self-confidence on mathematics achievement. In this respect, the economic, cultural and social capital of students are very similar to each other as the economic levels of the countries and individual families increase. These similarities highlight the differences between students' personal characteristics, wherein traits such as self-confidence have become one of the most important variables that determine students' mathematics achievement in recent years.
