Welcome to ENGR12L Engineering Circuits Lab Tom Rebold Monterey Peninsula College

Overview Goals and Philosophy for Online Circuits Lab Circuits Hardware Lab Kit Online Labs and Modalities Lab Activity Sampler

13 Goals for a Laboratory Course 1) Instrumentation and Measurement 2) Evaluate Models 3) Devise Experiments 4) Collect, Analyze, Interpret Data 5) Design, Build, Assemble 6) Learn from Failure 7) Creativity in Problem Solving 8) Psychomotor - Competence using Tools and Resources 9) Safety 10) Communication 11) Teamwork 12) Ethics 13) Sensory Awareness

Guiding Philosophy for Online Circuits Labs In anticipation of communication difficulties Keep hardware work simple Shift toward simulation – qualitative and quantitative Create fault proof experiments Provide support with Studio video by Rachel Lawton – most preferred Discussion forum Online office hours Classroom video – experimenting with TeacherCam
