FOCUS November 2006 InProfessors honor Bert K. Waits of and Franklintheir Demana extraordinary have made an indelible impact achievements. on mathematics education, hundreds of thousands of educators and countless students around the world. In addition to pioneering the use of graphing calculators to enhance classroom instruction, Bert and Frank co-founded the T3 • Teachers Teaching with Technology™ educator professional development organization and the highly-regarded T3 International Conference. The annual Demana-Waits Scholarship for Future Teachers, supported by Texas Instruments, continues to help college students pursue a teaching career in secondary school mathematics. Bert and Frank’s long list of accomplishments reflects their devotion to furthering mathematics education. We are proud to have shared their vision, having worked closely together in the development of TI’s first graphing calculator. Bert and Frank’s passion for teaching and learning mathematics through “the power of visualization” continues to inspire all that we do at TI and is sure to carry on for future generations of educators and students. Please join us in thanking them for their contributions and lasting legacy. Visit education.ti.com/us/bertandfrank.
