Scientific Modeling for Inquiring Teachers Network (SMIT’N): The Influence on Elementary Teachers’ Views of Nature of Science, Inquiry, and Modeling

This paper summarizes the findings from a K-6 professional development program that emphasized scientific inquiry and nature of science within the theme of scientific modeling. During the 2-week summer workshop and follow up school year workshops, the instruction modeled a 5-E learning cycle approach. Pre and posttesting measured teachers’ views of nature of science, inquiry, and scientific modeling. Teachers improved their views of nature of science (NOS) and inquiry by including scientific modeling in their definitions of how scientists work, the empirical nature of science, and the role of observations and inferences in science. Their definitions of science expanded from a knowledge-based orientation to a process-based orientation. Teachers added the use of mathematical formulas to their views of scientific modeling. Using scientific modeling as the central theme was effective in providing positive influence on teachers’ views of inquiry and NOS.     

Three-dimensional conceptual model for service-oriented simulation

In this letter, we propose a novel three-dimensional conceptual model for an emerging service-oriented simulation paradigm. The model can be used as a guideline or an analytic means to find the potential and possible future directions of the current simulation frameworks. In particular, the model inspects the crossover between the disciplines of modeling and simulation, service-orientation, and software/systems engineering. Finally, two specific simulation frameworks are studied as examples.
