The use of open questions in the mathematics classroom is often advocated to foster the development of students’ higher order thinking. However, Herbel-Eisenmann and Brey- fogle (2005) point out that ‘merely using open questions is not sufficient’ (2005, p. 484). This is especially true if the goal is to have students develop connections in a lesson that lead to an interconnected web of mathematical knowledge (Noss & Hoyles, 1996), rather than the students being ‘funnelled’ inShot on goalYou have become a strategy adviser to a group of new soccer recruits. Your task is to educate them about the positions on the field that maximise their chance of scoring. This means that when a player is dribbling the ball down the field, running parallel to the sideline, where is the position that allows this player to have the maximum amount of the goal exposed for a shot on the goal?Initially you will assume the player is running on the wing (i.e. close to the sideline) and is not running in the goal-to-goal corridor (i.e. running from one goal mouth to the other). Find the position for the maximum goal opening if the run line is a given distance from the near post. (Relevant field dimensions and a diagram of a soccer field as well as guiding questions are provided.)Source: (Adapted from Galbraith et al., 2007, p. 135)develop connections in a lesson are explored here in three different classroom scenarios about a task, Shot on goal (see box). These methods include triadic dialogue, funnelling and focusing.
