Dr. Osana is an educational psychologist who conducts research in reasoning and problem solving, with special emphasis on statistical reasoning, argumentation, and decision-making. Her research activity centres on the relationship between student cognitions and teachers’ thinking and practice, particularly at the elementary level. By working closely with teachers in the classroom, Dr. Osana is able to examine the factors that enhance teachers’ beliefs and classroom practice, such as content knowledge, understanding of student learning, and instructional design. Her work extends into areas of mathematics preservice education, critical thinking in at-risk settings, and literacy tutoring.
