Most academic disciplines include highly conceptual or abstract concepts that are difficult for students to grasp. For instance, building a solid foundation of conceptual knowledge for students is critical in engineering education (Streveler et al., 2008). An incomplete conceptual understanding hinders the development of central engineering competencies and expertise. However, it is a challenge for instructors to communicate these abstract and complicated concepts to students in engineering courses.
The cognitive theory of multimedia learning (Mayer, 2002) has suggested that students could learn more deeply using multimedia explanation, rather than mere verbal or textual explanation. This strategy seeks to illustrate complicated engineering concepts and promote situated understanding through short and memorable multimedia videos.

Understanding and knowing how to manipulate signal waveforms is one of the key skills that students need to develop in college engineering education. In the past 5 years, Dr. Lei Wei from the University of Central Florida tried to demonstrate various signal waveforms using pen and paper in his flipped learning course, EEL3552C Analog and Digital Communication Fundamental. The image below illustrates how Dr. Wei normally explained signal waveforms using this traditional method.
This series of videos was shown to students in EEL3552C in fall 2013. Students enjoyed watching these videos and found them very useful for understanding the course content and increasing general knowledge in engineering. They thought the online videos complemented the face-to-face lectures. Students also expressed a strong interest that they would like to see more videos like these in this class and other engineering classes.
