What is the overall goal to teach them? Do they need to be journal articles? The most “grabby” headliners I have noticed are on marketing items. Especially if you want to appeal to a younger audience, you could screenshot examples from Snapchat tabloids. “Top 17 ways to get your SO to notice you more,” “Prince Harry did the unthinkable,” “How to instantly cut fat out of your diet,” etc.
Their goal is to “hook” you into reading or scrolling or watching. Journal articles might do this on a much milder scale. “Novel method for disposing of plastics.” So you think: Novel? Must be revolutionary. Let’s find out.
Idk I hope that helps.
