In this column, the authors discuss apps useful in developing mathematical reasoning. They place these into a theoretical framework, suggesting how they could be used in an instructional model such as the Algorithmic Instructional Technique (AIT) developed by Vasquez (2003). This model includes four stages: modeling, practice, transition, and…

In a previous Techtalk column, Peterson and Caverly (2005) introduced the Community of Inquiry (CoI) model (Garrison, Anderson, & Archer, 2001) as a guide for online learning. The CoI model has maintained longevity and applicability to a variety of both synchronous and asynchronous technologies (Ice, Curtis, Phillips, & Wells, 2007). In this…

A theme for this year's Techtalk is keeping up with technology, emphasizing both professional development and new technology. This first column will look at the how and why of professional development. A second column will highlight wireless technology. The National Association for Developmental Education's Executive Board (NADE, 2001) resolved…

This article interprets two frameworks for how institutions and individuals can grow in "tech-knowledge." Technology growth opportunities for developmental educators are also reviewed. In the knowledge-based environment that is postsecondary education, professional development in technology must be ongoing as technology changes. Fortunately, a…

Describes a social-constructivist model of professional development arising from a collaboration between Southwest Texas State University's education department and New Braunfels (Texas) Independent School District. Teachers learn technology integration techniques from an instructionally strong "first-generation" of teachers trained at a…
