Examples of Hybrid PER Groups

One can think of other research groups as being mixed versions of the basic themes of PER. Some examples follow, and many more should be added.

University of Maryland, 1990s

Research by Joe Redish at the University of Maryland was heavily influenced by his sabbatical at the University of Washington (1991-1992) and the arrival of Richard Steinberg, a former UW post doc who helped guide the Maryland group (of Lei Bao, Mel Sabella, Jeff Saul, and Michael Wittmann) through the mid-90's.

Steinberg brought a UW research style to Maryland, while Redish was building on his work from the 80s on computer modeling (M.U.P.P.E.T.) and his collaborations with Laws and Thornton. The hybrid project was to apply the MBL tools described above to the creation of new tutorials for introductory physics classes. Another hybrid project of the time was to use a tutorials approach to teach quantum physics. This project happened in collaboration with Dean Zollman's Kansas State group. Both these projects were later published as the Activity-Based Tutorials.

Unique additions to this program arose from Redish and Steinberg's early collaboration on investigating student expectations of physics learning, Saul and Bao's work in survey analysis, and Wittmann and Sabella's use of p-prims in analyzing student data.

University of Maryland, 2000s

A second period of hybridization came at Maryland after 2001. In 1998, David Hammer (Ph.D. with Andy diSessa) joined the group and Andy Elby (also from Berkeley) began to collaborate with the group. From 1998 to 1999, the first PhD students graduated and slowly a new group arrived. When Rachel Scherr (a UW graduate) joined as a post doc and later research assistant professor, a new hybridization of research themes began. One could describe it as an application of knowledge-in-pieces models to tutorials development; in shorthand, bringing together UW and Berkeley directions of PER. The Open Source Tutorials came about as a result.

University of Maine, 2000s

The original PER program at Maine was begun by Rand Harrington, a UW graduate. He left in 2000, replaced by Michael Wittmann from Maryland. Shortly after, John Thompson (a post doc from UW) came to Maine. The group carried out a different hybridization of knowledge-in-pieces research (on resource development and coordination) and UW research themes (with less a focus on tutorials and more on Physics by Inquiry). Studies comparing the many forms of tutorial instruction were also carried out. Thompson and Wittmann later extended the program of studying the learning of advanced physics topics, using many approaches from Physics by Inquiry to teach about sound and quantum physics, while developing tutorials in mechanics (with Brad Ambrose, PhD with Lillian McDermott, former Thompson colleague at Grand Valley State U) and thermodynamics (with David Meltzer, first Iowa State and later UW).

Towson State University, 2000s

Cody Sandifer from San Diego State (PhD with Fred Goldberg) and Laura Lising from the University of Maryland (post doc with Joe Redish and David Hammer) are now collaborating at Towson State U.

University of Northern Iowa, 2000s

Larry Escalada from Kansas State University (PhD with Dean Zollman) had been at UNI for nearly a decade when Jeff Morgan from the University of Maine (PhD with Michael Wittmann) joined the group.
