\subsection{Intellectual Merit}
Peer-instruction has proven successful in outcome-oriented evaluations of techniques limited by currently widely available technology. This project will add process-oriented data to the research body around peer-instruction and study the effect of extensions to this technique, which we believe can significantly change both the process and the outcome of applying these techniques.
\subsection{Broader Impact}
+
Currently, every semester approximately 350,000 US students are taking introductory undergraduate physics courses similar to at least one of the courses at the participating institutions~\cite{aapt}.
For many of these students, it is both their first and their last formal exposure to physics. Students will go into a large spectrum of careers, with or without an understanding of the basic concepts of the physical world.

As an outcome of the NSF ITR grant Investigation of a Model for Online Resource Creation and Sharing in Educational Settings
(\#0085921, \$2,055,000, September 15, 2000 through July 31, 2005), LON-CAPA developed into a content sharing network of more than 15 institutions of higher education including community colleges and four-year institutions, as well as over 15 middle and high schools. In addition, LON-CAPA houses commercial textbook content from seven major publishing companies, and a commercial service company was established around the product at the end of 2004.

+\subsection{Creation of infrastructure}
The ported ConcepTest concept library (subsection~\ref{porting}) will be stored in the shared resource pool of the LearningOnline Network with CAPA (subsection~\ref{loncapa}), which
offers scalable cross-institutional content and rights management features. Where appropriate, gateways will be established to have different system components access the same
original content.
-An important feature of LON-CAPA for this study is its scalability and ability to absorb peak-workloads through cluster-wide load balancing. On campus of MSU, LON-CAPA has been used for timed online ``take-home'' exams by 400 students submitting 50 questions each within one hour.
+In the initial phase, the Interactive Learning Toolkit will be integrated with BQ, forming a new software package called LT3 (Learning Together Through Technology). The BQ
+program will be transformed to a LT3 laptop-based front end. This part will host the complete Interactive Classroom features of LT3. The ILT part will continue to be a
+server based software. The LT3/ILT will continue to be the environment where the instructor can prepare the content for his class by browsing the ConceptTest data base and integrate CTs into a
+given lecture. An important step will be possibility to upload the CTs into the LT3/BQ part for one lecture at a time and to automatically prepare them for the Interactive Classroom. After each lecture,
+the student responses are uploaded to the LT3/ILT part and made available for statistcal and individual performance analysis. This implementation
+strategy is the result of various tests which were run with a minimally integrated ILT/BQ software during a large physics class at Harvard. Results of this test phase
+will be disemminated in the next couple of months.
+
+In the next step, the CT library will be transfered to the LON-CAPA network as described above. The user interface for CT browsing and lecture integration in the ILT/LT3 will remain
+unchanged. The LT3 will be enabled to search the LON-CAPA CT resource pool and to render a static or randomized version into the LT3 environment. This will enable the LT3 as
+well as the LON-CAPA community to access the most recent version of each ConceptTest and allows them to track any changes which have been made by the individual authors. This
+integration step will enable us to carry out the proposed study with a minimum of logistical or technological challenges caused by the involvement of three different
+institutions. The specific architecture of this integration step are currently discussed. Both, the LON-CAPA and the ILT/BQ development team agree that such an integration
+will be possible.

The goal of computer-guided group formation is to generate student groups with differing initial responses. Group formation is limited by seating arrangements in a the lecture hall, unless time can be afforded for students to get up and walk around the lecture hall.

For classroom use, specialized tools similar to the existing ILT functionality need to be developed to provide the
instructor with a quick and comprehensive overview of response patterns of the more complex randomizing question types.

We also invested a great deal of effort disseminating our findings nationwide, as we feel that it is
crucial to share the results of our research. In the last several years, Eric Mazur and other members of the
group have given more than one hundred invited talks on peer-instruction in a variety of venues:
