Socratic Dialog-Inducing (SDI) Labs

SDI Labs [123 4] are "guided construction" labs featuring hands-and-heads-on experiments in introductory mechanics. Their effectiveness in promoting student crossover to the the Newtonian World has been demonstrated by rigorous pre-post testing [ 125 a-d]. For more information, including course materials, Mechanics Test Data Survey Form, the article Diagnostic Student Computerized Evaluation of Multicomponent Courses, and Research, Development, and Change in Undergraduate Biology Education: A Web Guide for Non-Biologists [REDCUBE] see the page on the research of Richard Hake.

Detailed information on SDI labs, a list of users, forums for communication, Teacher's guides, and sample lab exams are now available at the Harvard Galileo Server under "Hands On Methods."

SDI Labs #1 - 3 constitute the essential core of the present material and selected sections could suffice for initial testing of the SDI method at your location. Early versions of these three, along with ref. 3 are also available on the Physics Teacher's CD ROM Toolkit, available from The Learning Team.

Lab manuals

The labs are indicated below. They are all in Adobe Acrobat (AA) portable document file (pdf) form, readable using the free AA "Reader" Version 3.0 or later [6]. The asterisk "*" after the title indicates that a "Teacher's Guide" is available on request to R.R. Hake; see [7] for an introduction to the guides. Some guides are now available (password protected) at the Harvard Galileo Server fo llowing the menus "Hands On Methods => SDI Labs => Resources => Teacher's Guides" (Note: registration on the Galileo Web Server is required).
