TL; DL (Too Long; Didn’t Listen) 1. Need for research that experimentally addresses linear circuit analysis misconceptions. 2. Many misconceptions stem from physics misconceptions. We suggest focusing on addressing physics misconceptions first.

Misconception Example Students can take water analogies literally, believing electrons will pool behind resistors like water pools behind a dam.

Specific Math Misconceptions • Algebra manipulations : Incorrect solving of algebra equation [19][20] • Calculus manipulations : Believe sinusoidal means sine, calculating wrong cosine angles [7]

Specific Physics Misconceptions • Charge as a property of matter: Electrons carry positive charge [7]; voltage source provides charge [10] • Conservation of charge : Charge is used up in a circuit [10]; current is used up in a circuit [23][24][26]; voltage is used up in a circuit [23] • Electric fields and voltage : Voltage source supplies current [10][24][26][27]; battery supplies the voltage source which causes current [27] • Term confusion : Current related to potential energy [7][27]; voltage and current switch on and off, or positive and negative [9]; current and voltage are confused [26]; current/resistance are confused [26]; voltage is (or like) current that flows or moves [27]; voltage is measure of strength/ size/force of current [27]; voltage is pressure [27] • Incomplete metaphor : Current is like water that flows through a pipe [9][10][27]; that metaphor yielded a particular misconception: current pools behind resistors [27]

Conclusion 2 Physics: focus on addressing misconceptions. Math: also foundational.

Conclusion • Need research addressing misconceptions • Focus on physics (and math) • Future work: Expand literature search, experiments addressing misconceptions
