Knowledge and Skills Statement
In elementary grades, students used circuit diagrams to model open and closed circuits. In high school, students are expected to use schematics to model circuits and their components. The top image shows an example of a circuit diagram while the bottom image shows the schematic for the same circuit.

Summary: This study aims to know the effect of a STEM (Science–Technology–Engineering–Mathematics) approach on students’ cognitive structures about the topic of electrical circuits, as revealed through a Word Association Test (WAT). A study following a time series quasi-experimental research design was made to collect information about changes in students’ cognitive structures before and after a learning sequence about electrical circuits.

Summary: This article reports the development of a two-tier simple electric circuits test (2T-SEC Test). Simple electric circuits are introduced to students early in their school years and are an important part of the physics curriculum all the way to the university level. The average difficulties of the main concepts regarding simple electric circuits (open and closed circuits, electric current, resistance, series and parallel circuits, and electrical voltage) were calculated and compared.
