yes! that'll work.
Up to now I've been using WeBWorK in a purely formative sense. It has proved useful in identifying poor engagement among students.
Due to past issues of collusion I am now also usng WW for summative assessment.
The summatively assessed problem set consists of a mix of select an answer questions (SAQ's) (ie MCQ's, EMQ's and True/False Q's), calculable questions, 'show that' questions and 'including a diagram explain' questions. Given the last two types students must submit a hand written copy showing their working.
Given the summative nature of the assessment I wish to remove the option of students identifying answers in the SAQ's but at the same time give them the option to check their answers in the calculable problems before submission.
My idea (vain hope?) is that this will provide a non threatening high reward environment and that it may motivate them to start early and seek assistance if they electronically attempt the question incorrectly.
I'm not sure of future development plans for WeBWorK but what might be really neat is that if students could submit a file (tex, jpeg, pdf) in answer to a question that could be graded by hand similarly to an essay question.
Regardless of the future development pans for WeBWorK, presently thanks very much for getting back so quickly and the help.
