 \subsubsection{Correlation of In-Class and Exam Performance}
-A capability of our systems is that we can use the same question without modifications in online and bubble-sheet exam mode. Since in addition, questions are randomizing, we are able to include some of the same questions used in class on exams and quizzes. A similar study was previously conducted by Kashy~\cite{kashyd01} for homework questions.

 the current library of ConcepTests will be translated into LON-CAPA format, such that baseline data can be obtained across 
 different implementations and institutions. We will also transfer the CT rights and access management to the LON-CAPA system.

 \subsection{Computer-Guided Group Formation} \label{groupform}
 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.
 
-As a first step, seating arrangements in the lecture hall need to be coded into a computer-readable format -- both the BQ and the LON-CAPA group have experience in this area. Then an algorithm needs to be developed to find the optimum configuration of groups of $N$ nearest neighboring students that maximizes initial dissent within the groups. Fig.~\ref{formation} is a mock-up of a possible configuration of two nearest neighbors within a lecture hall. In small lecture halls, such a scheme might be projected at the front of the class, in larger lecture halls where two-way communication devices are used, the information might be directly sent to the students (e.g., ``turn to the student directly behind you'').

+In the intitial phase, the Interactive Learning Tollkit will be integrated with BQ, forming a new software package called LT3 (Learning Togehther 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/ILT 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. 
+
+Both integration steps will be carried out within the first year.
+
+The seating map to enable computer-guided group formation in the LT3  will also be implemented within the first year.
