| Abstract Title: |
Investigating student understanding of operational-amplifier circuits* |
| Abstract: |
We describe a systematic, multi-year investigation of student understanding of the behavior of basic operational-amplifier (op-amp) circuits. The participants in this study were undergraduates enrolled in upper-division physics courses on analog electronics at three different institutions, as well as undergraduates in introductory and upper-division electrical engineering courses at one of the institutions. Our findings indicate that many students complete these courses without developing a functional understanding of the behavior of op-amp circuits. We describe the most prevalent conceptual and reasoning difficulties identified (typically after lecture and hands-on laboratory experience) and discuss the implications of our findings for electronics instruction.
