Developing Mathematical Content Knowledge for Teaching: One Preservice Teacher and Her Planning

This paper describes how a new pre-service teacher engaged with mathematical content in order to learn it for teaching, during practicum. The results show that the PST learned mathematical content by initiating and carrying out a preparation phase prior to planning. This phase involved searching through internet sites and making notes that were then used to support her lesson planning and teaching. Implications for pre-service teacher education are also presented.
