Question

Oamara is researching the effects of screen time on children’s ability to pay attention. Which resources would be the most likely to have useful information?

an encyclopedia entry about the history of television
the blog of a middle-school student who loves video games
an interview with someone who has taught fourth grade for 27 years
a periodical describing recent research regarding TV time and school performance

Answer 1

Most useful: the periodical describing recent research regarding TV time and school performance — it will summarize current empirical findings and point to original studies.

Also useful: the interview with someone who has taught fourth grade for 27 years — gives informed, real-world observations and context (qualitative evidence), but it’s anecdotal, not conclusive.

Less useful: an encyclopedia entry about the history of television — okay for background/context but unlikely to contain evidence about attention effects.

Least useful: the blog of a middle-school student who loves video games — purely anecdotal and biased, not a reliable source for research.

If you want stronger sources, look for peer‑reviewed studies, systematic reviews/meta‑analyses, and guidance from reputable organizations (e.g., Pediatrics, JAMA Pediatrics, AAP, CDC).
