Abstract
Teacher education programs have a responsibility to develop teachers’ confidence as teachers in both mathematics and science, reducing the barriers known to affect the efficacy of teaching of these curriculum areas in the primary classroom. However, Pre-Service Teacher (PSTs) often lack the confidence in teaching mathematics and science. We propose an initial tool using the Cartesian Plane to assess PSTs confidence with specific concepts and how to teach these concepts in mathematics and science. We anticipate that the tool will inform teacher education programs, pedagogical practices and have further implication in the teaching of mathematics and science.
