TELPS: A method for analysing mathematics pre-service teachers' Pedagogical Content Knowledge

• A survey to analyse pre-service mathematics teachers' PCK is introduced.
• Pre-service teachers analysis of lesson plans is used to determine PCK.
• The survey indicates changes in elements of PCK can be determined over time.

A pre-service teacher's Pedagogical Content Knowledge (PCK) and their personal constructs of teaching develop throughout their teacher education program. PCK integrates generic pedagogical knowledge, mathematical teaching methodology and knowledge of the discipline of mathematics and this paper reports on a survey that can be used to assess a pre-service teacher's PCK. TELPS (Teacher Education Lesson Plan Survey) was developed to determine the PCK of pre-service teachers during their teacher education program. TELPS is shown to analyse pre-service teachers' PCK with some indication that the pre-service teacher's development of PCK can be observed.
