Analysis of Student Understanding of Basic AC Concepts


Book Description

This project began with a study on student understanding of the basic concepts of voltage, current, and power in DC and AC circuits. Protocol studies revealed that beginning student knowledge of the domain is "in pieces". Students had difficulty in differentiating key concepts such as voltage and current, lacked the ability to map from physical processes to abstract notation, and experienced problems because they had incomplete mappings for metaphors and analogies. Because of "invisible nature" of electricity, students had very few preconceived notions about the domain and most of what they learned was gained through instruction. In the second phase of the project, our emphasis shifted to a study on how to prepare students to learn difficult DC and AC circuit concepts, and to assess how instruction in these topics improved problem solving behavior. This led to our framework for Assessment of Domain Learnability (ADL) and the implementation of a computer environment, STAR-Legacy, that integrates instruction with dynamic assessment. Preliminary studies demonstrated improved student understanding and problem solving capability in the DC circuit domain. We also extended our AC protocol studies to characterize student understanding of more advanced AC concepts using problems dealing with voltage regulators and filter circuits.

Understanding AC Circuits


Book Description

Understanding AC Circuits covers the second half of a basic electronic circuits theory course, integrating theory and laboratory practice into a single text. Several key features in each unit make this an excellent teaching tool: objectives, key terms, self-tests, lab experiments, and a unit exam. This new edition has been thoroughly revised and updated by the authors to reflect the latest information on electronics. Understanding AC Circuits is designed with the electronics beginner and student in mind. The authors use a practical approach exposing the reader to the systems that are built with AC circuits making it easy for beginners to master even complex concepts in electronics while gradually building their knowledge base of both theory and applications. Each chapter includes easy-to-read text accompanied by clear and concise graphics fully explaining each concept before moving onto the next. The authors have provided section quizzes and chapter tests so the readers can monitor their progress and review any sections before moving onto the next chapter. Each chapter also includes several electronics experiments, allowing the reader to build small circuits and low-cost projects for the added bonus of hands-on experience in AC electronics. Understanding AC Circuits fully covers dozens of topics including single-phase and three-phase AC electronics; electrical generator basics; how to use a multimeter and oscilloscope in AC electronics; troubleshooting and testing circuits; tools and equipment; resistive circuits; inductive circuits; capacitive circuits; vector diagrams; series circuits; transformers; filter circuits; resonant circuits; decibels; waveshaping control; electronic symbols; soldering techniques; plus much more.
