• Every subject had accompanying experiments• Designed for immediate sensory feedback• LEDs as current or level indicators• LEDs as 1/0 indicators• Computer interface keeping score for the arcade game
• Physical reinforcement to the more abstract concepts
Syllabus Features---Experiment Rewards

• Morning lecture, afternoon lab, five days a week• Standard lab setup, working in pairs except for individual hi-fi
amp fab• Empty lab templates provided to indicate what should be
observed• Co-curricular modules: Biotechnology and artificial intelligence
discussions; laser sensor lab tour
Implementation

• Focus groups, exam, student comments, survey• Exam results: six students got 90% or higher• Example questions:
Program Outcomes
(Sophomore level)
(Junior level)

• Focus groups & end-of-semester surveys identify benefits for students and educators• Student gains:• Ability of identifying ECE in daily life• Hands-on experience: lab equipment and procedure,
debugging experience• “It works!”• High-average in mid-program exam; working, practical,
packaged audio amplifiers• Informed career decision
Program Outcomes

• Educator gains:• Early exposure to ECE material• Early experience of lab work and problems• Students appreciate:
• conceptual focus• immediate feedback in experiments
• Kolb Learning Styles: Convergers and Assimilators benefited likewise• Appeal to self-motivation effective
