Dear Trav, Many thanks for your lengthy reply. I did suspect the reason was to prevent students simply clicking all the boxes. No the lecturer does not want to do anything particularly tricky and I did suggest rewording the questions so he could use just straightforward multiple choice. It is very much a case of wanting to transfer what was a paper test (in pharmacy with multiple valid symptoms) to an electronic version without him realising that there are limitations doing it electronically especially if he wants it automatically graded. Cheers for the explanation about extra credit - it now makes sense and I am pleased to hear you say it was poorly worded! Had me confused. Alas as I suspected it isn't the magic solution to the situation above (because there isn't one). Appreciate the response.

Obviously it stops students from just clicking every box and then getting 100% for the question. I assume you're trying to do something tricky with the question type for a reason - is there another question type that might be appropriate? As for the extra credit, I think the definition is poorly worded because "no points are taken away" is misleading. The extra credit refers to the grade value of the test as a whole, not to individual questions, and it's not that points are not "taken away", just that they are not granted. If you create a test with two multi-choice questions worth 10 marks each and one question is extra credit then a student that answers them both correct will get 20 out of 10. A student that answers only one correct will get 10 out of 10 (because they either get the 10 marks for the question that was in the test, or the 10 marks for the extra credit question). If you make a multi-answer question worth 10 marks where two out of four responses are correct, and a student selects three possible responses (2 correct, 1 incorrect) then they will get 5 marks for each of the two correct responses, and lose 5 marks for selecting an incorrect response, giving them 5 out of 10 (assuming you have partial credit enabled for the question). Thus, if you create a test with one multi-choice question (Q1) worth 10 marks and the multi-answer question (Q2) as extra credit then the students may get 10 out of 10 for the test if they answer either question correctly. If they, as in the previous sentence, select 2 correct and 1 incorrect, then their grade will be 15 out of 10 (ie: 10 for MCQ, 5 for multi-answer). All the best, Trav. ------------------------------ Travis Cox Senior Learning and Teaching Consultant Learning Environments Information Services The University of Melbourne VIC 3010 T: +61 3 8344 7446 F: +61 3 8344 4341 E: [log in to unmask] ________________________________ From: Blackboard/Courseinfo userslist on behalf of Deswarte Richard Mr (CSED) Sent: Tue 29/04/2008 20:36 To: [log in to unmask] Subject: Multiple Answer questions and Extra credit Dear All, Does anyone know if you can prevent the deduction of points in multiple answer questions in a test? We use BB 7.3 but information on other versions would be useful as well. The default is that any incorrect answers are deducted from the number of correct choices in a multiple answer question. From the online manual it appeared that the extra credit function would do this but it doesn't. According to the manual: 'This option allows the Instructor to make the questions an extra credit questions as opposed to a regular question. If this option is selected points are added to the score if the questions is answered correctly; no points are taken away if the questions is answered incorrectly.' Certainly does not do that automatically as far as I can tell. Can anyone shed any light on what 'extra credit' actually does and how it works? Any responses much appreciated.
