There are many sources of professional development for K-6 teachers that help them learn how to use computers, but much less is available on how to use computers in classrooms to enhance learning. Members of the Department of Science and Mathematics Education at the University of Melbourne (Australia) have developed CLICK! (Computers and Learning in Classrooms: K-6), a professional development CD-ROM resource for teachers about effective uses of computer in the K-6 classroom. CLICK! comprises 36 professional development modules, 30 associated case studies, and video and multimedia materials illustrating how computers can be used to enhance learning. This project involved teachers and academics involved in teacher education from Australia and the United States and has resulted in a powerful resource to support K-6 teachers in integrating computers into their classrooms.
