ab: Summary: Students’ algebraic proficiency is debated worldwide. To
investigate the development of algebraic proficiency in Dutch secondary
education, we set up a study, in which 1020 students in grades 8‒12
took four algebra tests over a period of one year. Rasch analysis of
the results shows that the students do make progress throughout the
assessment, but that this progress is small. A qualitative analysis of
test items that invite structure sense reveals that students’ lack of
structure sense may explain the results: the majority of the students
were not able to deal flexibly with the mathematical structure of
expressions and equations. More attention to structure sense in algebra
education is recommended.
