Burde, Jan-Philipp; Weatherby, Thomas Sean; Kronenberger, Arthur – Physics Education, 2021
Understanding simple electric DC circuits often represents a great challenge to many students in lower secondary schools. As a result, students' knowledge of this subject is often dominated by alternative conceptions, even after instruction. One of the reasons for these learning difficulties is the intangibility of key physical quantities and…

Wee, Loo Kang; Lee, Tat Leong; Chew, Charles; Wong, Darren; Tan, Samuel – Physics Education, 2015
This paper reports a computer model simulation created using Easy Java Simulation (EJS) for learners to visualize how the steady-state amplitude of a driven oscillating system varies with the frequency of the periodic driving force. The simulation shows (N = 100) identical spring-mass systems being subjected to (1) a periodic driving force of…
