Abstract: A year-long PD program was provided to four teachers teaching integrated algebra in a New York City Title I public school. The PD comprised teacher authoring of a curriculum that incorporated TI-Nspire? technology. Teacher TPACK levels of development were measured through a TPACK Levels Rubric, created and validated by the authors. The rubric was used to assess the teachers’ written artifacts and observed behaviors. Results indicated that the pattern of change in a given teacher’s TPACK level over the period of a school year was non-linear. The classroom teaching was either at the same level or lower than the TPACK level of the corresponding lesson plan. The students performed better in the courses taught by the teachers with higher TPACK.
