Videos of Children’s Thinking

Twelve video clips of children’s thinking have been selected for use by students using Part I and Part III of the Reconceptualizing Mathematics textbook. Information on each of these clips is found in the textbook Appendix A.

The first six video clips were a product of Integrating Mathematics and Pedagogy (IMAP), a federally funded, 3-year project designed to integrate information about children’s thinking about mathematics into mathematics content courses for college students intending to become elementary school teachers. Contact the Principal Investigator, Dr. Randy Philipp, rphilipp@mail.sdsu.edu, if you wish to get more information on this project.

The seventh video clip was created as part of a research project funded by NSF, Mapping Developmental Trajectories of Students’ Conceptions of Integers. Contact the Principal Investigator, Dr. Lisa Lamb, lclement@mail.sdsu.edu, if you wish to get more information on this project.

The remaining videos were filmed as part of research project conducted by Dr. Susan Nickerson. This project focused on upper elementary students’ thinking about algebra and geometry. For more information on this project, contact Dr. Nickerson, snickers@mail.sdsu.edu.

Video for Section 3.2: Strategies

In this video, we see three students….

Video for Section 3.3: Javier

In this video, Javier, a fifth-grader with limited English proficiency, uses mental strategies to multiply 6 x 12 and 12 x 12.

Video for Section 6.1: Rachel

In this video, we see a teacher teach the same lesson twice: once in a procedural way and once in a more conceptual way. We also meet Rachel, a student in the class, who reflects on the two approaches.
