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

3. 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

4. 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

5. The Circuit Kit Components case Breadboard with barrel jacks
DC wall adapters
DMM
Analog Discovery multi-instrument (USB Scope and Waveform Gen)
