Two-tier Simple Electric Circuits test (2T-SEC test)
Purpose
The Two-tier Simple Electric Circuits test (2T-SEC test) assesses students’ qualitative understanding of current, resistance and potential differences. The two-tier structure of the assessment allows to analyze students’ alternative conceptions on simple circuits.
Population
The 2T-SEC test is designed to be used in populations that range from middle school to introductory college / university courses.
