8 Portable Analog Circuit Design Kit Independent Learning Active hands on learning. Anytime, anywhere. Less Dependence on Limited University Resources Lab equipment : oscilloscopes, function generator, arbitrary waveform generators, power supplies, logic analyzers, pattern generators, spectrum analyzers, bus analyzers Limited and/or incomplete parts & kits Works with standard curriculum Integrates practical experience with analytic skills MATLAB integration allows students to acquire signals from experiments, enabling them to improve their MATLAB skills and deepen their understanding of the circuits they are designing and characterizing. Affordable $99. No more than the price of an engineering textbook. 8

9 Growing Ecosystem Design Resources for Students open-source technical support documentation, exercises, lab projects, and instructional videos Expansive Support Library Online library of information including text books YouTube lectures over 181 electrical engineering online labs/tutorials for MATLAB Expands and grows with Student Skills learned analog design, analog troubleshooting, instrumentation, programming, building algorithms, analyzing signals, schematic use, and (future) PCB design will be used in the students upper level classes and throughout the rest of their career. 9

11 Learning Styles and Instruction Many students are challenged to develop robust understanding when presented with only abstract concepts and theories. Many types of learning: Auditory, Visual, Kinesthetic or 'hands-on Few students rely on only one type of learning Need to match instructional techniques with learning styles Lectures Auditory, Visual representation of audio, Visual Reading notes/textbook Visual representation of audio and Visual Analytic problem solving Visual Simulations Visual Experiments Kinesthetic, Visual, and Auditory

12 Retention of Material 10 percent of what students read 26 percent of what students hear 30 percent of what students see 50 percent of what students see and hear 70 percent of what students say 90 percent of what students say as they do something Stice, J.E., Using KoIb s Learning Cycle to Improve Student Learning, Engineering Education, vol. 77, no. 5, Feb. 1987, pp I feel like I understood how circuits worked immediately after assembling a lab in this lab-in-a-box. During my other lecture class it took me a few days to grasp the idea of parallels and series working together, along with resistors. Once I did these labs, it just made sense as I assembled and observed it. sophomore CpE student I never knew what gain was until I connected a speaker to the inverting amplifier senior EE student

13 Square Wave Generator Can be used as voltage source in a number of experiments Concepts: Voltage division Charging characteristics of RC circuit Ideal op amp Voltage comparator Nonideal op amp Output voltage is limited by the power supplies Maximum current output Input resistance Slew rate Max. frequency of operation

20 Stimulating Student Designs 50% of the experiments in the first circuits lab course and all of the experiments in the second circuits lab course contain elements of design. Last experiment in both courses is a two-week long design Students may substitute the design with one of their own ANDY Board Design Competition Held annually by the student chapter of Eta Kappa Nu in April Individual and teams of undergraduates are allowed to enter 2 8 groups have participated during the past three years All have incorporate light and/or sound in their designs 20
