Using The Web To Encourage Student-Generated Questions In Large-Format Introductory Biology Classes, James T. Colbert, Joanne K. Olson, Michael P. Clough

Ecology, Evolution and Organismal Biology Publications

Students rarely ask questions related to course content in large-format introductory classes. The use of a Web-based forum devoted to student-generated questions was explored in a second semester introductory biology course. Approximately 80% of the enrolled students asked at least one question about course content during each of three semesters during which this approach was implemented. About 95% of the students who posted questions reported reading the instructor’s response to their questions. Although doing so did not contribute to their grade in the course, approximately 75% of the students reported reading questions posted by other students in the class ...


Utilizing Video-Clips And Written Work To Help Preservice Teachers Understand Student Thinking, Tonia Land Jan 2007

Utilizing Video-Clips And Written Work To Help Preservice Teachers Understand Student Thinking, Tonia Land

Retrospective Theses and Dissertations

The National Council of Teacher of Mathematics has put forth a vision for how mathematics should be taught that is quite different from the traditional model that most preservice teachers have experienced throughout their education. Cognitively Guided Instruction (CGI) is an example of a program that exemplifies that vision, but challenges exist for teacher education programs to prepare preservice teachers for an approach of this type. Presenting video clips and written work are two methods that have been used by teacher educators to help prepare preservice teachers. This project reiterates the literature surrounding this topic in that video clips and ...
