This qualitative research study used a layered case study (Patton, 2002) to examine the technological, pedagogical, and content knowledge (TPACK) of a group of inservice secondary mathematics teachers as they participated in a technology-based lesson study. Using the TPACK Development Model (Niess, 2009) as a lens, this dissertation examines interactions of the group members during lesson study meetings as well as individual case studies of four of the six participants. Data were gathered from initial surveys, initial and post-interviews, initial and post-classroom observations, writing prompts, and transcriptions of lesson study group meetings. Data were analyzed to determine the TPACK development levels for different themes of the model at different stages during the lesson study process. Thick descriptions are provided of actions and quotes from the participants that exemplified various TPACK development levels. Findings indicated that the design and purpose of technology-based lesson study provided participants opportunities to practice actions from the higher levels of the TPACK Development Model during the lesson study. Based on classroom observations, half of the participants demonstrated practices that indicated increases in TPACK development levels following the lesson study. Those participants with less experience with technology in their educational backgrounds demonstrated greater positive changes. Participant responses to interview questions and writing prompts indicated that experiencing learning with technology and observing students' thinking served to prompt changes in their own practices.
