Before beginning to enter terms in the search boxes, it is worth your while to think about those terms. What are alternative terms for "Service Learning?" You might consider Community Service, Active Learning, Partnerships in Education, Experiential Learning, or School Community Programs.
The first step in finding this information is to choose the appropriate databases. For Service Learning in Elementary and Middle Schools, choose Education from the Research by Subject tab on the Booth Library homepage.
The two databases you want to choose from the resulting list are ERIC and the Professional Development Collection. Choose either one of those databases; then, when the EBSCO list of databases comes up, you may select both.
Chances are, though, that when you do the search, you will end up with a results lists of many thousand articles.
Thus, the power of the not. You may remember learning about Boolean searching. Putting together two terms with the word And means that both terms must be present for the item to appear in your results list. Putting those same two terms together with the word Or means that your results list will include items with either of the two terms. Not, on the oither hand, will take away any items that include the term that is not wanted in the results.
Try some of these terms in a new search to find additional articles.
