Speech Map

This visualization shows the flow of talk during your lesson, laid out turn by turn. You can see the distribution of Teacher Talk and Student Talk over the duration of your lesson in two ways:

Divided (Top): The two types of talk are separated, with Student Talk above and Teacher Talk below. Each circle represents a Statement, and the size of each circle corresponds to the length of the Statement. White gaps indicate Pauses.

Unified (Bottom): The two types of talk are shown together in sequence. Darker sections indicate Overlaps. White gaps indicate Pauses.

Your lesson included 103 total statements. Of these, you made 73% while the Students made 27%.

A burst is a series of short(er) Statements by one Speaker in between Statements by another.

Bursts of Teacher Talk generally indicate that a teacher is providing guidance or feedback as a student explores a question or concept. As students become more comfortable with a topic, expect to see more of these in between bursts and blocks of Student Talk.

Do you see a lot of dark sections in the bottom Speech Map? This means that there were a lot of speech overlaps in your lesson. Overlaps occur when the teacher and students are talking at the same time.
