Elementary school science focuses on the early phases of science inquiry: observation, description, data collection, reflection, and reporting. Technologies afford opportunities to scaffold and extend the domains of inquiry, but successful adoption depends on their integration with classroom organization and practice. In elementary schools, small group and(More)
To obtain a better estimate of course offerings required to run a four year curriculum in Computer Science, ten years of student flow was simulated. The simulation was based on the Computer Science curriculum at Southeastern and its student's progression as of Fall, 1984. Mentioned topics will include (1) model construction (2) model validation (3)(More)
