Advancing the concept of triangulation from social sciences research to mathematics education

The paper suggests interpreting the term triangulation, commonly used in social science research, as multiple ways of solving a problem in the context of mathematics education. The availability of different technological tools provides new perspectives on problem solving as modeling from where ideas for problem posing stem. Using topics from geometry and trigonometry, triangulation is considered through lens of teacher education. Reflections by teacher candidates on activities which are shared and reviewed in the paper indicate future teachers’ readiness to implement the pedagogy of triangulated perspectives on problem solving and posing in their own mathematics classrooms.
