Education Source is the primary database in Education studies. Begin your search here.
Once here you will want to familiarize yourself with the features which will make your searches most efficient.
I have requested the database to search for 'classroom management' and 'secondary education or high school' and 'student attitudes', but have also placed limiters on how much information I want returned.
I have limited my results to full text, January 2013 to February 2017, from Academic Journals, published in English. I also recommend the Scholarly Peer Reviewed limiter if you are looking for well researched scientific findings.
