Eyetracking showed students often answer word problems without looking at the algebraic expression, leading the curriculum to treat expression-writing as an induction task with the formula row moved to the bottom of the table¶

Subclaims¶

q2 i? Students looked at the problem scenario but not the expression about 13% of the time, at the expression 54% of the time, and at neither almost 34% of the time. → Ritter 2007 q1 i? Based on these data, the curriculum presents the formula row at the bottom of the table so students solve individual problems first and generalize to the expression. → Ritter 2007 (2)

q2 · i? · associational · r?

An eyetracking study in which students completed a table of values based on a word problem; students looked at the problem scenario but not the expression about 13% of the time and at the expression 54% of the time, showing strategy use did not match expert expectations.

"Gluck (1999) found that when students were answering a question such as the first question in Figure 1, they looked at the problem scenario but not at the expression about 13% of the time. Students looked at the expression (sometimes along with the scenario) 54% of the time."

As a result of the eyetracking and other data, the Cognitive Tutor curriculum treats finding algebraic expressions for simple word problems as an induction task: the formula row is now presented at the bottom of the table, after the two question rows.

"The formula row, shown as the second row in the table of Figure 1, is now presented at the bottom of the table, after the rows corresponding to the two questions."
