Current studies are focused on the 5th grade classroom with approximately 100 students. As well, as of July 2007, the system is being developed to integrate directly into classroom curriculum for the coming semester with included tools such as Front of the Class Betty, developed at Stanford University.
As of 2013 it has been used in many experiments to test the effectivness of building and examining dynamic models for instruction in scientific domains. In several studies of Betty’s Brain by Biswas and collaborators, they trained students by having them create models of the oxygen cycle in a water-based ecosystem and then assessed them by having them create models of the nitrogen cycle in a land-based ecosystem. This is called a transfer test and it is a standard technique in learning experiments. In both activities, the systems were presented with resources and the modeling language was the qualitative diagram language built into the system. Experimental controls tested various hypotheses to begin to determine what worked and what did not. This is a powerful environment for beginning to understand what is effective about building simulations. Other useful systems for studying the effects of modelling for learning are IQON and Colab.
