Hi.

I am currently helping develop a web-based tool at Sussex for use on our object-oriented programming courses.
The tool will manage students workgroups (who is working with who on what and when) and then allow students to submit work for set exercises over the internet, which will then be automatically tested, giving different types of feedback (errors, tips etc).


Once the tool is in place, we will be evaluating it's use.
Chris - I'll keep you informed of our progress!

Regards.

Sallyann.

Hi,

This is a two part question that is loosely related to the previous thread:

Lets say I have a class of students performing a group of simple progamming assignments in Java (for sake of argument). By assignments I'm thinking of exercises that performs simple temperature conversion, calculate average rainfall, calculates a factorial, or a set of classes to exhibit a particular behaviour through published methods.

Does anybody know of any papers that try to address the problem of automated (by computer) validation/checking of student programs, potentially providing feedback regarding student assignments? I appreciate that a lot of checking and validation is performed by a compiler (and the interesting error messages that are created), and that code can be automatically tested through a mechanism like JUnit, providing they are integrated into the software that is to be tested (and written properly)... Do you know whether anybody has investigated or implemented a more 'student friendly' mechanism for automated checking/validation of submitted programs which could be related to particular assignments or programming tasks?

Also, if we have a sample program, does anyone know of a tutoring system that may assist students through the automatic generation of natural language questions derived from a submitted program text? I appreciate that most of the time a compiler facilitates the generation of these questions, through user interpretation...

All references and comments greatfully appreciated,

Many thanks.

Chris
