Leanne Ketterlin Geller, Ph.D., is engaged in research and scholarship focused on supporting all students in mathematics education through application of instructional leadership principles and practices. She has served as Principal Investigator for federally and locally funded research grants emphasizing the development of formative assessment procedures in mathematics and valid decision-making systems for students with diverse needs in the general education curriculum. Specifically, she investigates:

a) Formative assessment design frameworks using modern test theory, including Item Response Theory;

b) Empirical impact of accommodations and other test changes on the validity of test-score interpretations and uses;

c) Implications of using technology to implement universal design of assessment principles to support accessibility; and

d) Mathematics teachers’ decision-making with a focus on integrating research-based instructional design and delivery principles with teacher content knowledge.

The context of her research efforts is middle-school mathematics with an emphasis on supporting algebra-readiness. She publishes and presents to audiences focused on research as well as practice in the areas of mathematics education, measurement and assessment, and special education with the intent of broadly disseminating her research findings to make the greatest impact.

Her research is informed by her experiences in K-12 education. She taught high-school science in public schools and is trained as a K-12 administrator. During these experiences, she focused on supporting all students. In addition to teaching advanced placement, college-preparatory, and general science courses, she designed and taught science classes for culturally and linguistically diverse students using principles and techniques of Sheltered Instruction. Also, she served as a coordinator for the AVID (Advancement Via Individual Determination) program that is intended to encourage and provide academic supports for college-bound students from typically underrepresented populations.
