Please help - Bit confused how Workshop Module works!

by Chris Daly - Thursday, January 3, 2013, 4:25 PM

I am having great difficulty in understanding this Module

Hope someone can help!!

I have an assignment that requires self assessment + 3 Peer Assessment

I have results

Lets say Student 1 in Grades Received column

49(27) Student 1 - Self

41(30)< Student A

56(28)< Student B

29(29)< Student C

Grade for submission 44 - I understand this - average of the 4.

Part #2 I click on the 41 for student A.

I have 6 Aspects each out of 10 - scores for this student are out of 10: 8,6,0,6,8,7 Sum = 35

All Aspects weighted 1 except Aspect 2 = 5

(Overall Grade for submission = 70, Grade for assessment = 30)

My question is HOW is the 41 arrived at??

many thanks

Chris

I assume you are using the Accumulative grading strategy. As described at the docs page for this strategy, the total grade of submission is calculated as a weighted mean of individual aspect's grades. The total grade from the reviewer "Student A" is

( 8/10 + 5*6/10 + 0/10 + 6/10 + 8/10 + 7/10 ) / ( 1 + 5 + 1 + 1 + 1 + 1 ) = 0.59 = 59%

and then

70 * 0.59 = 41.3

Many thanks for your help - simple when one thinks about it!

The next question relates grade for assessment /30

I assume if a student returns amark close to the average then they score well?

I am using 2.3 and hence do not have the ability to calibrate each student - I assume this will become available shortly?

Finally in 2.3 I assume I cannot anonymise the students?

Thanks

To anonymize, you can adjust the student role permissions. Please see the Workshop FAQ's for more information. You can anonymize at the activity, course, or site level.

Well, yes. But let me suggest to read the whole section about the grade for assessment in the docs as it is not that easy as it might look at the first sight. Most notably, it compares two assessments' individual aspects, not the total grade. So you can easily have two assessments giving the same grade for submission but receiving different grade for assessment (see the linked docs page for example).

do not have the ability to calibrate each student

What do you mean by that? You as the teacher can override calculated grades. Again, see the relevant docs page for more info.

Hi David

I think I have made it OK - have completed 2 workshop activities and reaonably confident now. Many Thanks.

Can you now tell me a little about the Grading Evaluation Method?

When using Comparison with best Assessment what essentially does very lax, lax, fair, strict, very strict what effect does each have on results?

Thanks

As noted at the docs page linked above, this "parameter of the calculation is how strict we should be, that is how quickly the grades fall down if they differ from the best one". The chart of the impact can be seen at http://docs.moodle.org/dev/Workshop_2.0_specification#Grade_for_assessment
