Dalhousie University Dr. Barry Paton LabVIEW Enhanced Learning in the Classroom, Dorms and Labs Role of a University Teacher • • • • • • Expert lecturer Tutorial leader Problem Solver Class Administrator Builder of Labs, King TA Quiz Maker, Marker and Adjudicator WEB Guru Not all students want to ‘make your day’. Students need to hear it in the classroom see it demonstrated and do it in the lab. Effective Learning Evolution of Technology • • • • • • • • • 1962 Thin Film Transistor Operational Amplifiers 70’s Digital Electronics 80’s Microprocessor revolution 90 Graphical User Interface 91 LabVIEW moves to Windows 96 LabVIEW Student Edition 98 Internet Instrumentation 00 Vision, Smart Sensors, Remote Panels National Instruments Today Gives the educator all the tools to measure, analyze and present data is a scientific manner. This allows students to spend more time making real measurements and testing theory with actual measurements. It is exploration science and engineering!
