PTMT materials are based on research on teaching and learning and have been iteratively revised based on empirical studies with teachers. For more information read our research-based Guiding Framework (PDF).
Early PTMT materials were disseminated as textbooks with accompanying electronic files. In 2015, the project materials went completely digital to include a web portal with free access to materials and technology files for each of the modules: An Integrated Approach to Data Analysis and Probability, An Integrated Approach to Geometry, and An Integrated Approach to Algebra. In 2017, we expanded to include a set of video interviews and classroom practices in Voices from the Field. In addition, with new statistics standards and online tools, we reinvisioned several chapters from the original data and probability module in a new Statistical Investigations module. PTMT offers all materials for free as open educational resources at go.ncsu.edu/ptmt.
The Algebra materials consists of 7 chapters that provide in-depth dynamic technology explorations of important topics such as variables, equality, rate of change, and functions.
The 7 chapters in the Geometry materials engage learners with how dynamic approaches to geometry can change the ways students understand concepts such as properties of polygons, transformations, similarity, and symmetry.
In Data Analysis and Probability, there are 6 chapters in this set of materials that utilize tools such as TinkerPlots, Fathom, Excel, and graphing calculators to engage in statistics investigations using multivariate data. Topics addressed include distributions, variability, bivariate relationships, probability, and simulations.
In Statistics Investigation, there are 4 chapters in this set of materials that use large multivariate data and a new free online tool, CODAP, to engage in similar investigations that are in Chapters 1-4 in the Data Analysis and Probability materials. These new materials are developed as part of the ESTEEM project, aiming to enhance statistics teacher education through developing e-materials.
Voices from the Field provides a collection of video clips representing how real teachers use technology in their mathematics classrooms. Some clips illustrate how teachers and students use technology in lessons. Other clips show teachers and experts discussing issues related to their planning and implementation of technology.
