14. Issues and Challenges Hardware and Software Quality of components Robustness Initial cost Maintenance – Hardware Maintenance – Software Internet Distribution Development of Interactive Community Batch vs. interactive Simple free standing Complex shared Utility of specific experiments Narrow or broad applicability Infrastructure costs Economy of scale Summary of Student Assessments (Heat Transfer for Weblabs) The weblab was educational. The weblab was fun. I prefer the weblab/hands on experiment. High agreement Moderate agreement 50/50 split Student-grade vs. industrial-grade architecture
