Sample+3.07

I selected these as my “good” student samples. These students correctly connected the addictive nature of drugs to the effect they have on dopamine levels in the brain. The first sample brings in the idea that availability also affects how addictive a drug is. This idea came up in several other student samples. I didn’t teach them this, they simple included it.

The second students sample shows a basic understanding of how the body develops tolerance to certain drugs. He also tied this into how drugs can cause depression when the user attempts to quit.

For these students my instruction worked. I noted a dramatic increase in student understanding between the pre and posttest. Looking at the pretest response and using them to inform my instruction definitely made my instruction more effective.
