Audio and video recordings of students engaged in collaborative mathematical modelling tasks

<p dir="ltr">In this study, 156 eighth-grade students (ages 13-14) from ten classes participated, with a near-equal gender split. Six mathematics teachers from five public secondary schools, chosen for their interest in collaborative modelling, volunteered to be involved. The sessions were video- and audio-recorded, including separate audio recordings of the teachers. </p><p dir="ltr"><br></p>
