TV: The urban myths shaken
This is a good article to use to stimulate a discussion on cause-and-effect. In the first paragraph there is a "no effect" claim and in the second a claim that five hours of study produces poor results. From their own experience students should discuss these two claims and the six dot points in the article which expand upon them.
What is their opinion of the results indicating that performance does seem to decrease as the number of hours watching television increases past three? How does this correspond with the headline about "student TV myths"? Do they think there is a beat-up here?
With respect to five hours of homework being associated with poorer performance, what other variables could students think of which might be associated with both of the other two [e.g., lack of student ability, language difficulties, exaggeration when responding to survey questions]?
What is student opinion about the association of reading for pleasure and high test marks? Does the first cause the second? Again, what other variables might be associated with both?
Where to next?
