Computer enhanced curricula may enable more teachers to create exploratory and inquiry based lessons, but in most cases supporting software have only been realized as practice tools for specific rote learning skills. Drills do little to help students develop higher-order reasoning and problem-solving skills. With more computers in the classroom, the assumption was that computers would be integrated into curricula with a high usage of educational software, but research suggests that this assumption has not been borne out (Powell & Okey, 1994; Tyack & Cuban, 1995). Our general argument is that systems whose usability characteristics have been designed to meet teachers\" needs and that can be easily tailored to meet specific teaching objectives are more likely to be incorporated into everyday teaching practices. One type of computer-based activity that enables teachers to engage students in exploratory learning is an educational simulation. Many educational software packages that build simulations have limited usability because they have unmodifiable, limited modifiable or difficult-to-modify functionality. Still others are useful, but are too expensive for many schools to afford. These packages fall short of achieving the ultimate goal of providing useful classroom simulation technology \" providing teachers with the option of building simulations from scratch or reusing existing simulations by adapting their functionality. Because teachers have limited time to learn new technology or develop new simulations, this research focused on developing a new framework that would help teachers create easily adaptable and reusable customized educational materials, encouraging them to use these materials to build and extend simulations in collaboration with their students. We began our study by analyzing the currently available tools for visual construction of educational simulations; we used the results of these analyses to develop an alternative environment\"SimBuilder.
