In the first two offerings, we mainly focused on thetheoretical contents of data mining with only one team project as a practical experiment.The assessment results were not as good as expected in the first two offerings. Given theapplied nature of data mining, we decided to introduce a practice-oriented approach in thethird offering to better serve the course outcome. Based on the recommendations from theACM SIGKDD Curriculum Committee, the objectives of integrating the hands-oncomponent into the theoretical knowledge delivery are five-fold. a) Learn to use data mining systems by using some data mining software. b) Implement some data mining functions including

easy to usescripting system for defining the system in three steps. First its constitutive mathematicalrelations are defined, then a drawing is created that depicts the system, and then the drawing isanimated. The system is described mathematically by a state-space model (i.e, A, B, C and Dmatrices). The drawing of the system is described in terms of graphics primitives commonlyused to depict linear systems. For translating mechanical systems this consists of suchcommonly used objects as springs, masses, dashpots and sliding friction, along with dynamicallyresized arrows to show force and displacement. For electrical systems, primitives exist thatrepresent resistors, capacitors, and inductors as well as arrows to show current and dials to
