A substantive segment is defined as a meaningful contribution to an ongoing activity, such as problem solving, or a relevant response to the Tutor’s explanations [1]. For example, to the Tutor explanation shown below the Tutee’s response would be coded as a substantive one:

Example (1):

    -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 segment
