Sample searches to try:
Put it all together:
Here are database-friendly searches, with unnecessary words removed:
Instead of: "What are the causes of test anxiety?"
Use: "test anxiety" AND cause*
Instead of: "What's the effect of the pandemic on mental health of college students?"
Use: COVID-19 AND "mental health" AND "college students"
Instead of: "Does using social media increase anxiety among teenagers?"
Use: "social media" AND anxiety AND teen*
Database searching summary:
Use filters to limit to peer-reviewed articles or set a date range (last 5–10 years for current trends).
Look at subject terms in ERIC and Education Source — they help you discover official topics and narrow results.
Save keywords and authors from articles you like to build stronger searches.
Tip for Success: If you find one really good article, look at the subject terms listed with it and use those terms in your next search. That’s often how you uncover the best materials in education databases.
