Physics education research (1980–2000) has identified many common misconceptions, has led to construction of standardized diagnostic tests, has prompted development of targeted teaching strategies.
Interactive Lecture Demonstrations use computers in lectures to log and display data in various representations, rely on carefully controlled teacher-class interactions, claim very substantial gains in student learning.

Conclusions: Is there a cultural bias? Is the laboratory component crucial? Is there no such thing as a magic bullet?
