Some education materials in the design and experiments of electric circuits for engineering education are updated in the way of PEL (Project/Problem Based Learning) with circuit simulator SPICE (Simulation Program with Integrated Circuit Emphasis). As one of the most representative chaos circuits, we adopt here the Chua circuit which consists of a 3-segment piecewise-linear resistor, active resistor, and energy-storage elements. This piecewise-linear resistor is realized using operational amplifiers, according to the circuit design shown by Kennedy. Experiments with this circuit, the circuit simulation and numerical simulation provide students with the guide lines for Nonlinear Dynamical System and Chaos Engineering and with problems to obtain problem-solving techniques and skills and to study new items of nonlinear electric and electronic circuits.
