We share here results from a quasi-experimental study that examines growth in students' algebraic thinking practices of generalizing and representing generalizations, particularly with variable notation, as a result of an early algebra instructional sequence implemented across grades 3-5. Analyses showed that, while there were no significant differences between experimental and control students on a grade 3 pre-assessment measuring students' capacity for generalizing and representing generalizations, experimental students significantly outperformed control students on post-assessments at each of grades 3-5. Moreover, experimental students were able to more flexibly interpret variable in different roles and were better able to use variable notation in meaningful ways to represent arithmetic properties, expressions and equations, and functional relationships. This study provides important evidence that young children can learn to think algebraically in powerful ways and suggests that the earlier introduction of algebraic concepts and practices is beneficial to students.

The nature of prospective mathematics teachers' pedagogical content knowledge: the case of multiplication of fractions Işıksal Bostan, Mine; Çakıroğlu, Erdinç (Springer Science and Business Media LLC, 2011-06-01) The purpose of this study was to investigate prospective mathematics teachers' knowledge of common conceptions and misconceptions that sixth and seventh grade students had about multiplication of fractions. In addition, prospective teachers' knowledge of the sources of these misconceptions and strategies they knew to overcome these misconceptions was examined. Data were collected from 17 Turkish prospective teachers at the end of the spring semester of the 2004-2005 academic year. A case study design was us...
THE THINKING-ABOUT-DERIVATIVE TEST FOR UNDERGRADUATE STUDENTS: DEVELOPMENT AND VALIDATION UBUZ, BEHİYE; Ubuz, Behiye (Springer Science and Business Media LLC, 2015-12-01) Two studies were conducted for the development and validation of a multidimensional test to assess undergraduate students' mathematical thinking about derivative. The first study involved two phases: question generation and refinement of the Thinking-about-Derivative Test (TDT). The second study included four phases as follows: test administration, generalizability analysis, confirmatory factor analysis, and subgroup validity analysis. Findings suggested that the 30-item multiple-choice TDT, which comprises...
The effects of a mathematics teaching methods course on pre-service elementary mathematics teachers’ content knowledge for teaching mathematics Seviş, Şerife; Koç, Yusuf; Department of Elementary Science and Mathematics Education (2008) The purpose of this study is to examine the effects of a mathematics teaching methods course on pre-service elementary mathematics teachers’ content knowledge for teaching mathematics (CKTM). In order to accomplish this purpose, pre-service mathematics teachers’ understanding of basic concepts and procedures in school mathematics, use of mathematical definitions, presentation of mathematical content to students, identification of common errors, misconceptions and solution strategies and evaluation of unusua...
Mathematical Knowledge for Teaching the Function Concept and Student Learning Outcomes Hatisaru, Vesife; Erbaş, Ayhan Kürşat (Springer Science and Business Media LLC, 2017-04-01) The purpose of this study was to examine the potential interrelationships between teachers' mathematical knowledge for teaching (MKT) the function concept and their students' learning outcomes of this concept. Data were collected from two teachers teaching in a vocational high school and their students through a function concept test for teachers and students, follow-up interviews with teachers, and classroom observations. Findings indicated that teachers' MKT and students' learning outcomes were related to...
Fostering prospective mathematics teachers' proportional reasoning through a practice-based instruction Piskin Tunc, Mutlu; Çakıroğlu, Erdinç (Informa UK Limited, 2020-11-01) The purpose of this study was to investigate prospective middle school mathematics teachers' proportional reasoning before and after receiving a practice-based instruction based on proportional reasoning. The Proportional Reasoning Test, semi-structured interviews and observations of student teachings were used to collect data about the participants' proportional reasoning. The results indicated that prospective teachers improved their proportional reasoning by completing a practice-based instruction. Befor...
