TI-Nspire technology, a new generation of graphing calculators, was integrated into high school integrated algebra curriculum. Four teacher-participants were supported through a yearlong professional development emphasizing the use of technology through an inquiry based approach. The data included the teachers’ perceptions about TI-Nspire technology, teachers’ proficiency with TI-Nspire technology, quality of instruction determined through classroom observations, and the frequency of technology use in the classroom based on questionnaire completed by the students. Data analysis indicates that there is a significant positive correlation between quality of instructional practice, quality of use of technology, and teachers’ level of TPACK. In general, teachers with better perceptions used technology in the classroom more frequently, were more proficient with the technology, had higher quality of instructions, and higher level of TPACK. Implications on years of experience and pre-service training are discussed
