The effectiveness of the SaLVO pedagogy on students' performance on proportionality

Abstract

The aim of this study is measuring the effectiveness of the SaLVO pedagogy, coherent educational material. The main research question was: To what extend is the SaLVO pedagogy effective on cognitive level for dealing with proportionality problems? This was tested with a Dutch 8th grade SaLVO maths group and a maths control group that used the Numbers & Space material. Both groups took the same newly developed test. No differences in test scores were found, overall and on question-level. The SaLVO pedagogy was not more effective on cognitive learning gains than the Numbers & Space material for proportionality problems.
