Explains how a spreadsheet can be an effective modeling and simulation tool for studying electrical circuits. Highlights include Kirchoff's rules and matrices algebra; a pilot experiment with preservice teacher education students in a physics class; the teacher's role; student attitudes; curricular aspects; and the effectiveness of the spreadsheet…

Laboratory exercises, field observations and field trips are a fundamental part of many earth science and environmental science courses. Field observations and field trips can be constrained because of distance, time, expense, scale, safety, or complexity of real-world environments. Our objectives were to develop an environmental virtual field…
