This study examined the effects of using a combination two novel technologies on the development of knowledge and understanding of ecological science concepts for a small of preservice primary teachers, who had self-identified as having low prior background knowledge in science concepts and low confidence in their abilities in teaching science.…

Technological Pedagogical Content Knowledge (TPACK) is a theoretical framework that has enjoyed widespread applications as it applies to the integration of technology in the teaching and learning process. This paper reviews the background for TPACK, discusses some of its limitations, and reviews and introduces a new theoretical framework, 21st…

The purpose of this study is to examine the ways in which PSMTs' professionally notice middle school students' mathematical thinking on a technology enhanced mathematical task. Findings show that every preservice mathematics teacher included a discussion of the middle school students' interaction with the technology in their noticing prompts,…

This article describes an introductory computational thinking (CT) lesson that was implemented into five educational technology classes at a large university in the southern United States. A total of 88 undergraduate and graduate students participated in the lesson. The project was the result of a collaboration between education faculty and a…

This multiple case study provides a lens into the ways three prospective elementary school teachers (PSTs) engaged in online discussion blogs when exploring the geometric concepts of area and perimeter. The online discussion blog protocol utilized reform-based instruction consistent with social constructivism. Through collaborative discussion and…

In this paper, we propose the mathematical cognitive technology noticing framework for examining how mathematics teachers evaluate, select, and modify mathematical cognitive technology to use in their classrooms. Our framework is based on studies of professional and curricular noticing and data collected in a study that explored how secondary…

The purpose of this study was to investigate elementary pre-service teachers' content knowledge in algebra (Linear Equation, Quadratic Equation, Functions, System Equations and Polynomials) as well as their technological pedagogical content knowledge (TPACK) in teaching algebra. Participants were 79 undergraduate pre-service teachers who were…

This paper presents the findings of a study that examined pre-service teachers' development of knowledge about technology, pedagogy and content (TPACK) during a mathematics pedagogy course focused on elementary school mathematics in the United States. Data sources included work samples from pre-service teachers as well as an open-ended survey…

While technology has potential to improve the teaching and learning of mathematics, research indicates that teachers struggle in their efforts to implement technology-rich mathematical tasks in their classrooms. Effective technology integration in mathematics requires teachers to be able to apply their classroom knowledge related to mathematics…

Technological pedagogical and content knowledge (TPACK) has been advanced as a construct to describe teachers' understandings related to effectively teaching with technology. This study examined the development of TPACK of two teachers during their mathematics teaching after participating in a learner-centered professional development (LCPD)…

In this paper, we report on our efforts to support teachers' development of mathematical knowledge for teaching through online professional development focusing on authentic engagement in collaborative mathematical problem solving. In particular, this paper seeks to explore and understand the relationship between online mathematical collaboration…
