This is a tough topic to search for because the concepts addressed are broad: education, popular culture, engagement, "street smarts" or practical knowledge vs. formal intellectualism. 

You can think about the aspects of the article that most interest you and search for other scholarly articles in an interdisciplinary database like Academic Search Complete or, potentially a subject-specific database for education like ERIC. Here are a few terms for you to pick and choose from to get you started:

• "street smart*" AND "book smart*"
• education AND "popular culture"
• (teaching OR learning) AND "practical intelligence"
• "teaching the conflicts"
• anti-intellect* AND education

If this is new to you, you might find some context using a reference source like Credo Reference. Try search terms like:

• "culture wars"
• "media AND popular culture"
• (or, try any of the terms from the article you're unfamiliar with)

Also, if you are interested in the liberal arts education aspect of the article and want to build background knowledge about this branch of education in today's world, try searching another reference source (which has a great Bibliography section with many links), CQ Researcher. Try searching:

• "humanities education"
