This study investigated whether a four-week professional development workshop for math teachers helped improve their ability to integrate technology into instruction and teach math concepts. Instruments for data collection included four different types of surveys that asked questions concerning their technology skills and confidence in teaching various math topics. Results of the study revealed that the professional development workshop did improve their technology skills in using graphing calculators and different software programs, as well as increasing their overall confidence in teaching different math topics such as fractions, percentages, real numbers, etc.
