His published research was on the topic, “Moving Beyond Test Scores: A Study on How to Improve High Performing High Schools.” As part of his dissertation research, he collected and analyzed over 100,000 data fields to determine the correlation among student achievement, demographics, and school climate at high socioeconomic status schools. He continues to work with UCLA to support future doctoral candidates. Dr. Mabery has presented at numerous state and national conferences and workshops. His presentations have been on topics, such as personalized learning, social justice in math education, inquiry-based learning, questioning, 21st century skills, and implementing new standards. He was selected to be in the Chinese Bridge Delegation, where he travelled to Beijing and Shannxi in the People’s Republic of China with the College Board to collaborate with local educators on student learning.
