Content Quality Concerns:
There are some dead-ends; that is, in some parts of the module, the user must use the back button several times to get back to the beginning. Some of the discussion on the web pages could be improved.
Content Quality Strengths:
Goals are stated within different parts of the module. There is an "Ask the expert" link, which will lead the student through a series of scaffolding questions to (hopefully) arrive at the correct answer. Follow-up questions are provided at the conclusion of the lesson that encourages students to interpret what they just learned.
Ease of Use Concerns:
Students might get confused by clicking on a wrong link. It could be improved by a table of contents at top that gives links to all pages.
Ease of Use Strengths:
It was easy to navigate through the web pages and respond to the questions posed.
Potential Effectiveness Concerns:
Should be updated to include p-value method for determining significance. Degrees of freedom explanation does not necessarily match that in some major textbooks. User may get frustrated with dead links and dead-end paths. Should link to one of their own applets to let user put in mean, sd to calculate the mean.

Potential Effectiveness Strengths:
Has effective explanations of correct answers as well as good explanations when user selects the incorrect path. Exposure to mini case studies like this are helpful, since they communicate the entire process of a statistical investigation.
