• One set of students read a chapter and then hear a lecture about it

• Another set of students analyze and graph data, deciding what they think is important to graph

• # A third set played around with graphing the data and then heard a lecture about it.

“This class is very hard and many of you will failso you need to study really hard.”

How does this impact university student motivationto learn the material?

a. increases b. decreases

Focus groups and interviews indicate is demotivating for university students. Psychology studies support.
