Third-grade students are participating in a classroom experiment investigating the impact of instruction derived from a research-based Early Algebra Learning Progression. Students completed a pre-assessment item addressing their abilities to justify a conjecture about the sum of three odd numbers. While they were largely unsuccessful on the assessment, through the course of the classroom intervention students are beginning to develop representation-based arguments and provide generalizations using facts about the sum of even numbers and odd numbers.

Third- through fifth-grade students participating in a classroom teaching experiment investigating the impact of an Early Algebra Learning Progression completed pre- and post-assessment items addressing their abilities to engage in functional thinking. We found that after a sustained early algebra intervention, students grew in their abilities to shift from recursive to covariational thinking about linear functions and to represent correspondence rules in both words and variables.
Middle school mathematics teachers' pedagogical content knowledge in relation to statistical reasoning
Gokce, Rukiye; Kazak, Sibel (2017-01-01)
To investigate middle school mathematics teachers' pedagogical content knowledge (PCK) with regard to statistical reasoning, an interview protocol was developed and used with nine teachers. This paper focuses on one of the problems in this interview protocol (Basketball problem) to illustrate teachers PCK in relation to four components: big ideas, student responses, student difficulties, and instructional intervention. Our analyses showed that levels of teachers' PCK varied in each component. Teachers had d...
Investigation of pre-service elementary mathematics teachers’ self-efficacy beliefs about using concrete models in teaching mathematics
Pişkin, Mutlu; Çakıroğlu, Erdinç; Bulut, Safure; Department of Educational Sciences (2010)
The main purpose of the study was to investigate pre-service elementary mathematics teachers’ personal efficacy beliefs and outcome expectancies about using concrete models in teaching mathematics. Data were collected from the pre-service teachers in the middle of the spring semester of 2008-2009. Pre-service teachers were junior students enrolled in elementary mathematics teaching program at a public university. Six instructional sessions based on using concrete models in teaching mathematics were carried ...
Grade 6 students' abilities to represent functional relationships
İşler Baykal, Işıl; Stephens, Ana; Fonger, Nicole; Blanton, Maria; Gardiner, Angela; Knuth, Eric (2017-01-01)
This paper reports results from Grade 6 students' written work on a functional thinking assessment item. The results show that students who experienced an early algebra intervention during Grades 3-5 were more likely to successfully represent a function rule in words and variables than students who did not. Also, both comparison and intervention groups of students were found to be more successful representing a function rule in variables than in words. The results underscore the impact of early algebra on s...
Middle school mathematics teachers’ mathematical practices in teaching slope, linear equations, and graphs in technology enhanced classroom environment
Yemen Karpuzcu, Seçil; Işıksal Bostan, Mine; Department of Elementary Education (2017)
The aim of this study was to examine an in-service middle school mathematics teacher’s mathematical practices in teaching slope, linear equations and graphs in a technology enhanced classroom environment while enacting an instructional sequence that was designed based on the national curriculum. The technology utilized in the study was GeoGebra materials within computers that were developed by the teacher and the researcher to be used for the instructional sequence. The data was collected during the spring ...
