ab: Summary: Gaining an accurate understanding of variables is one challenge
many students face when learning algebra. Prior research has shown that
a significant number of students hold misconceptions about variables
and that misconceptions impede learning. Yet, teachers do not have
access to diagnostic tools that can help them determine the
misconceptions about variables that their students harbor. Therefore, a
formative assessment for variable misconceptions was created and
administered to 437 middle- and high-school students. Analyses from the
test scores were found to exhibit strong reliability, predictive
validity, and construct validity in addition to important developmental
trends. Both teachers and researchers can use the test to identify
students who hold misconceptions about variables.
