This interactive project is based on statistics reported in an article we read: Using Cooperative Learning in a Large Introductory Statistics Class. Paragraphs 28 and 29 of tht article provide the following statistics.

"Preliminary findings indicated that, on average, students' scores improved when cooperative learning exercises were used. I would hesitate, however, to use these findings to say that more learning had taken place. These tests were not standardized.

"29 Exam Number 1 covers topics 1 through 4 as mentioned earlier. In the class in which cooperative learning exercises were not used, 8.28% of the students' scores on this exam were below 60, and 8.92% of the scores were in the 60's. When cooperative learning exercises were used, only 2.03% of the students' scores were below 60, and 5.08% were in the 60's. This gives some indication that weaker students may benefit. Similarly, on Exam Number 3, there was a lower percentage of scores below 70 when cooperative learning exercises were used. This exam covers topics 8 and 9 as mentioned earlier. When cooperative learning exercises were not used, 28.76% of the students scored below 60, and 18.95% scored in the 60's. This changed to 20% scoring below 60 and 13.51% scoring in the 60's when the exercises were used."

1. This is making me crazy. Can you make a table that will make sense of this?
