Quantifying Uncertainty and Analyzing Numerical Trends (QUANT) 1 is a yearlong professional
development program for high school mathematics teachers that is designed to develop their statistical
proficiency for teaching. The approach used to develop such proficiency is technological pedagogical
content knowledge in the areas of measurement, data collection, data analysis, probability, and
statistics, combined with a classroom implementation focus on selecting, setting up, and enacting cognitively demanding tasks. This paper describes the QUANT program, its aims, the role of technology in the program, and the results from a series of exploratory investigations to measure and evaluate the program’s effectiveness. These studies have involved a total of 23 practicing teachers, and they have been used to refine and shape this ongoing professional development effort.

The QUANT program is designed to develop teachers’ technological pedagogical content knowledge
(TPACK) in order to improve their statistical proficiency for teaching. TPACK is an integration of a
teacher’s content knowledge, pedagogical expertise, and facility with technology (Mishra & Koehler, 2006;
Niess, 2005; Niess et al., 2008). TPACK is the “Total PACKage” for teaching with technology (Thompson &
Mishra, 2007–2008, p. 38). QUANT does not seek to better a teacher’s technological knowledge in
isolation but rather in combination with pedagogical techniques and content knowledge. Thus, the QUANT
professional development program is aligned with the Mathematics TPACK Framework of the Association
of Mathematics Teacher Educators (2009). The technology used in QUANT includes the
TI-Nspire CAS [computer algebra system] (2010) handheld computer and associated computer software
as well as interactive digital boards, the TI Navigator local area network system for the TI-Nspire CAS, and
a variety of handheld data collection devices used in conjunction with the TI-Nspire CAS.
