Description of the Videos

A number of the lessons follow a launchexploresummarize format. The teacher first introduces or setsup a class task, activity, or experiment. Then the teacher provides students time to engage in the mathematical task/activity/experiment. The teacher then concludes with a discussion or lecture about the overarching mathematical idea(s) in the lesson.

Many of the lessons in the videos include both small group and whole class discussions in which students are working on a mathematical task, activity, or experiment that requires a significant portion of the lesson’s time.

Some of the teachers in the videos demonstrate instructional practices and mathematical tasks that have the form but not the function of those advocated by the NCTM Standards.

The videos include teacher and student reflections on teaching and learning; teacher voice over and interpretation of some of the events in the classroom videos; edited, full lengths segments of the classroom lesson; segments of video focusing on individual and groups of students engaging in mathematical tasks

Usefulness of the Videos

The videos of the classroom lessons are useful in modeling the setup and implementation of highlevel mathematical tasks as well as the setup and implementation of procedure without connections tasks.

The videos of the classroom lessons are useful in modeling patterns of discourse advocated in

NCTM Standards (1991, 2014) as well as traditional IRE discourse patterns.

The videos of the classroom lessons are useful in modeling instructional practices that vary along the continuum between traditional, direct instruction/transmission practices and problem/studentcentered, NCTM (2014) Principles in Action aligned practices.

The teacher reflections are useful in providing insight for the teacher’s instructional decisions and the student reflections are useful in providing insight about the lesson from the learner’s perspective.

A number of videos provide segments of video focused on individual or groups of students working on a mathematical task that are useful for representing students’ mathematical thinking and reasoning around the mathematical ideas in the lesson.
