Abstract

The use of simulation can help the learner to understand complex topics, such as signals and systems. This paper presents how to teach the IC Timer (NE 555 model) for future STEM teachers. This IC is a popular active component used in various fields; it can generate square wave signals and vary the Duty cycle. This paper proposes a course consisting of eight materials; it can be taught to future STEM teachers to understand the IC Timer NE555 concept carefully. The virtual laboratory practicum was chosen as the primary approach to provide initial understanding to future teachers about the square wave generator and Duty cycle controller. Besides, virtual laboratories are the right choice in engineering courses because they can minimize the risk of damage to electronic components and measuring instruments. Once future STEM teachers pass this proposed course, they can teach students using a virtual laboratory (simulation setup) before being forwarded to a hands-on laboratory. Circuit WizardTM is the best option as a virtual laboratory because it provides the needed properties: passive components (i.e., virtually fixed resistors, electrolytic Capacitors, and Ceramic Capacitors), Active components (IC NE555), DC Sources (e.g., Battery), and Instruments (i.e., Virtual analog Oscilloscope)
