WODB Part 3

Today when students walked in I already had the room set up in a huge circle (15 sets of 2 desks) with the samples of WODB A to O that the two classes created yesterday. You can see them in the Day 2 post. As students walked in I handed them 15 choice and reason slips. Students were instructed to start at a letter and work their way around the room picking, top left, bottom left, top right, bottom right for each WODB and writing down their reason for choosing this option. They then folded their ballot and put it in the envelope which was also on the desks. It looked like this.



 

 

 



Once students worked their way around the room I had them analyse the data from the sample they started with. Here are the results:

 



Once this was done students filled in a sheet summarizing the reasons that were given. We then went back and looked at the criteria for what makes a good WODB. Here it is:



Students were then instructed to rank the A to O samples individually from strongest 1 to weakest 15 by looking at the samples, the final data of the distribution and comparing this to the criteria.

The back of the room was set up and looked like this for the ranking to occur.



Here are the slips.



And the final averages of the students rankings versus my rankings.

IMAGE	OVERWIJK RANK	STUDENT AVERAGE RANK
A	6	10
B	7	2
C	5	6
D	14	8
E	15	5
F	9	7
G	2	4
H	10	12
I	1	3
J	11	1
K	9	15
L	13	14
M	4	13
N	3	11
O	12	9

From what I can tell students valued the equal distribution heavily and I valued the distribution and the math equally ( now there is a surprise! ).

Lastly I really liked the structure of this 3 day lesson. I think you could do this in any course - including non-math courses.

Hope you enjoyed. I did.
