  1. Peter Chalk, IoE & SBU Assessing Students' Learning When Using Software Engineering Webworlds

  2. Background • Web-based interactive learning environments (Webworlds) • Modelling capabilities - exploratory or expressive • Model as an 'object to think with' can be a powerful tool • Expressive modelling using diagramming tools freely available on the Web

  3. Methodology & Results • Methods for researching, monitoring, providing feedback and assessing work • Using a collaborative Web space (BSCW) • A method for analysing the 'learning paths’ • Preliminary data analysis appears to support the claim for enhanced student-centred learning

  4. Java Flow Graph Editor

  5. JSP Editor

  7. Preliminary results • BSCW team areas, event lists and files stored recorded, some metrics gathered & results analysed • Mark for the quality of their JSP design, flow graph analysis and coding/testing is a crude measure of their learning • All students who did respond to feedback and improve their model achieved an A or B grade. • Students of higher ability made best use. All groups with learning paths scored A & had most days when BSCW events occurred

  8. Textual analysis "Very interesting that tools [& code] used by engineers can be found" "I know there are errors in the design as I was unable to illustrate the nested loops in the generated code" "When I accessed his flowgraph I found an obvious mistake"

  9. Conclusions & what next • Confirm need for objects to think with & executable model • BSCW satisfaction with learning role • Appreciation of apprenticeship learning • Tool to identify possible paths from the daily event lists as they accumulate • Assess process of student-centred learning
