Factors Mediating the Use of Online Applets in the Lesson Planning of Preservice Mathematics Teachers
Journal of Computers in Mathematics and Science Teaching Vol. 22, No. 4 (2003) pp. 323–344
This article reports on a study of 18 preservice mathematics teachers' pedagogical thinking when using online applets in their lesson planning. The applets facilitate the investigation of mathematical relationships. The goal of the study was to...
Factors Affecting Pre-service Mathematics Teachers’ Lesson Planning with Learning Objects Supporting Higher Level Thinking
Society for Information Technology & Teacher Education International Conference 2004 (2004) pp. 4432–4437
We present a study of 16 middle school pre-service teachers' mathematical and pedagogical thinking with a level 4 mathematics learning object (level 1=recalling, 2=applying, 3=understanding, and 4=extending). The learning object used in the study...
E-Learn: World Conference on E-Learning in Corporate, Government, Healthcare, and Higher Education 2003 (2003) pp. 478–485
In this paper we propose a scheme for classifying the mathematical thinking facilitated by learning objects. With references to examples of existing learning objects, we describe four levels of mathematical thinking: 1 = recalling, 2 = applying, 3 = ...
Middle School Pre-service Mathematics Teachers’ Perceptions of Mathematical Beauty in Online Module Discussions
Society for Information Technology & Teacher Education International Conference 2004 (2004) pp. 4438–4445
We present a study of over 100 middle school pre-service teachers' online discussions of mathematical beauty. The goal of the study is to identify how the pre-service teachers perceive mathematical 'beauty'. The pre-service teachers were part of a...
World Conference on Educational Media and Technology 2002 (2002) pp. 556–561
Despite major differences in course delivery, the critical components of effective online mathematics teacher education may not be different from the critical components of effective face-to-face mathematics teacher education. Research indicates...
World Conference on Educational Media and Technology 2004 (2004) pp. 2374–2380
In this paper I explore what we might mean by mathematical 'thinking' in the context of learning objects and start a discussion about the design and pedagogical features that might be involved in the development of 'thinking' objects, that is,...
Society for Information Technology & Teacher Education International Conference 2006 (Mar 19, 2006) pp. 3726–3731
In this paper I relate intertwined fragments of the case story of one of the digital mathematical performances I have designed, developed, used and researched in an online mathematics teacher education course. The immediate goal for such...
Society for Information Technology & Teacher Education International Conference 2003 (2003) pp. 1794–1801
Pre-service elementary mathematics teachers need romantic experiences with mathematics - opportunities to (re)discover the pleasure in mathematics and the beauty in mathematical thinking. In this paper we report on our research on pre-service...
World Conference on Educational Media and Technology 2007 (Jun 25, 2007) pp. 3532–3537
In this paper we discuss the design goals of a set of Digital Windows into Mathematics (DWMs) that we are in the process of developing. Our goal is to create DWMs whose multimedia-rich content will challenge and disrupt typical assumptions about...
Journal of Computers in Mathematics and Science Teaching Vol. 23, No. 3 (July 2004) pp. 275–298
In this paper we focus on applets that support mathematical investigation. In the context of analyzing and redesigning an applet from NCTM’ s Illuminations Web site, we consider two interrelated issues: (1) how the pedagogy of mathematical...
