|Abstract:||Traditional approaches to teaching variables often begin with problems students can already solve arithmetically. Varying instructional method across conditions, we developed multimedia story sequences with systems-of-equations problems whose solution requires using variables. Sixth graders from two US schools (n = 163) completed two one-hour learning sessions and a delayed posttest weeks later. Across all conditions, sixth graders’ performance on the posttest was comparable to samples of 12 eighth graders post-learning and 20 ninth graders pre-review.|
