“…Some technologies brought about new ways to enhance instructional delivery by the teacher or increase processing power by relieving learners from complex calculations. Other solutions, which are at the focus of this paper, were meant to provide new ways to learn mathematics with dynamic, digital representation of mathematical ideas (Hoyles & Noss, ; Tran, Smith, & Buschkuehl, ; Young, ). These spawned several genres of educational technologies such as the microworlds (eg, Hoyles, Noss, & Adamson, ; Kynigos, ), dynamic mathematics environments (eg, Hadas, Hershkowitz & Schwarz, ; Leung, ; ) and recently also technologies for embodied interaction (eg, Abrahamson & Howison, ; Jackiw & Sinclair, ).…”
