Developed by the Center for Science Education at the nonprofit Education Development Center in Newton, Mass., this free online guide is intended to help high-school science teachers evaluate the vast array of learning resources available on CD-ROM and the internet. Called “Selecting Computer-Based High School Science Curricula: A Guide for Teachers,” the resource confronts the challenge of using technology to enhance classroom science instruction. The guide provides a series of prescribed questions for educators to consider as they review computer-based materials. The questions cover four key educational areas: student learning, teaching and professional development, equity, and feasibility. The site also supplies informational profiles of 12 electronic learning tools in particular.
