Deep follow-up
a deep follow-up, which is an elaborative inference that extends what the tutor said .[1] Examples of deep follow-ups are as follows:
Context: Each of the valves consists of flaps of tissue that open as blood is pumped out of the ventricles. -Tutor:“blood actually flows out through there.” -Student: This contracts like a balloon and forces this venous blood up here. ---> deep follow-up
Context: At first the molecules of sugar are more concentrated in and around the sugar cube and less concentrated in the water farther from the cube. -Tutor:“This cube of sugar is disintegrating, breaking apart, expanding into all spaces . . .” -Student:Until, until equilibrium is accomplished. ---> deep follow-up
shallow follow-up
a shallow follow-up is an elaborative paraphrase of what the tutor said. .[1] Examples of shallow follow-ups are as follows:
Text sentence #1: Human life depends on the distribution of oxygen, hormones, and nutrients to cells in all parts of the body and on the removal of carbon dioxide and other wastes. -Tutor: “Basically, what we are talking about is the circulatory system is an exchange of materials.” -Student: You take out the waste and you put in the nutrients. ----> shallow follow-up
Text sentence #16: Each of the valves consists of flaps of tissue that open as blood is pumped out of the ventricles. -Tutor: “OK. So opening and closing, what would that do?” -Student: It would allow the blood to enter like from the atrium without it falling straight through. ----> shallow follow-up
Substantive segment
We reserve this move mostly for mathematical practices. A substantive segment/response is defined as a meaningful contribution to an ongoing activity, such as problem solving, or a relevant response to the Tutor’s explanations [2]. For example, to the Tutor explanation shown below the Tutee’s response would be coded as a substantive one:
-Tutor: See this equation is true for constant acceleration. Now the acceleration is constant here. Forces are not changing on the weight so the acceleration is constant.
-Tutee: The initial velocity is zero then. ---> Substantive response
