The main purpose of the study was to investigate the role of mathematics historybased model-eliciting activities (MEAs) on seventh grade students’ understanding of negative integers. The study was conducted in one public middle school in Istanbul, in the Fall semester of 2018-2019 academic year. A qualitative educational case study design was employed with 29 seventh grade students. A set of integer questions were implemented twice to the participant students as an initial and a follow-up assessment. After the initial assessment, data collection procedure was continued by implementing three mathematics history-based MEAs. The data sources for this study were written worksheets of each group from the implementation of mathematics history-based MEAs, initial and follow-up assessments of each student, video and audio records of the implementation of activities. The data were analyzed by content analysis. The findings of this study indicated that mathematics historybased MEAs helped students to better make sense of negative integers, improved students’ understanding of negative integers and mathematical reasoning and justification capabilities in operations with integers. In the implementation process of activities, it was observed that most of the students are more productive and concentrated while they are studying as groups on a real-life related mathematical model. With the light of these findings, it is suggested that integration of the mathematics history into modeling perspective could be considered as an alternative teaching method for different mathematics topics in different grade levels. This study also suggests that the mathematics history-based MEAs could also be used to improve professional development of mathematics teachers to understand the role of such activities on students’ understanding and to enhance teachers’ teaching portfolio.

An investigation of mathematics achievement of eighth grade students with respect to their learning styles
Kurbal, Serkan Süleyman; Çakıroğlu, Erdinç; Department of Educational Sciences (2011)
This study aimed to investigate the differences in mathematics achievement scores of the eighth grade students with respect to their learning styles. Mathematics achievements of the eighth grade students were determined by the number of correct answers given in the mathematics subtest of Level Determination Examination (abbreviated in Turkish as SBS) which was administered in June 2009. Mathematics achievements of the eighth grade students were also determined by teacher-assigned mathematics grades which we...
A study on pre-service elementary mathematics teachers’ subject matter knowledge and pedagogical content knowledge regarding the multiplication and division of fractions
Işıksal, Mine; Çakıroğlu, Erdinç; Department of Secondary Science and Mathematics Education (2006)
The purpose of this study was to examine pre-service mathematics teachers’ subject matter knowledge, pedagogical content knowledge, and the relationships between the two on multiplication and division of fractions. For this purpose, pre-service teachers’ understanding of key facts, concepts, principles, and proofs, their knowledge on common (mis)conceptions and difficulties held by the elementary students, their strategies of teaching these concepts, and representations they use to reason their understandin...
A phenomenological study on mathematics teachers having experience with innovative learning activities: views, enablers,and barriers
Erbasan, Elçin; Çakıroğlu, Erdinç; Department of Mathematics Education (2021-2-10)
The purpose of the study was to investigate middle school mathematics teachers’ views and experiences regarding innovative mathematics learning activities. This study also aimed to determine enablers and barriers in the process of the activities and teachers’ suggestions that may lead the educational stakeholders to increase the qualityofmathematicsinstruction and accordingly, student learning. Phenomenological research was conducted with thirteen middle school mathematics teachers ...
The Effects of teaching linear equations with dynamic mathematics software on seventh grade students’ achievement
Doktoroğlu, Rezzan; Çakıroğlu, Erdinç; Department of Elementary Science and Mathematics Education (2013)
The purpose of this study was to investigate the effects of teaching linear equations with Dynamic Mathematics Software (GeoGebra) on seventh grade students’ achievement compared to the regular instruction. Randomized posttest-only control group design was utilized in the study. 60 seventh grade students (32 girls and 28 boys) of a public school in Yenimahalle district in Ankara participated in the study. The study was conducted in 2011-2012 fall semester, lasting 9 class hours in three weeks. The data was ...
An investigation of mathematics anxiety among sixth through eighth grade students in Turkey
Birgin, Osman; Baloğlu, Mustafa; Catlioglu, Hakan; Gurbuz, Ramazan (2010-12-01)
The purpose of the present study is to investigate mathematics anxiety among 220 sixth through eighth grade Turkish students in terms of mathematics achievement levels, perceived enjoyment of the mathematics teaching method, perceived enjoyment of mathematics, and perceived help with mathematics from parents. The Mathematics Anxiety Scale for Primary School Students (Bindak, 2005) was used to assess the levels of mathematics anxiety. A 3 x 2 factorial analysis of variance results showed that there was not a...
