Engineering Mechanics I (EK301)
• Required COE introductory engineering course– Fall 2012: 240 students; 4 sections; 4 faculty– Spring 2013: 140 students, 3 sections; 3 faculty
• Two 2-hour lectures per week• Analyze forces on static structures– Graphical, mathematical analysis
• Course restructuring: Spring 2012

Motivation to change
• Multiple sections, multiple faculty: disparity• Strong interest in more examples• Discussion of graphical analysis• Anecdotal evidence for success of in-class
problem solving
![Page 4: Improving Active Learning and Instant Feedback in an Introductory Engineering Course Caleb H. Farny Sean B. Andersson Dept of Mechanical Engineering BU.](https://reader037.fdocuments.net/reader037/viewer/2022110319/56649c3a5503460f948e323c/html5/thumbnails/4.jpg)
Influences• Peer learning
– Group environment• Enabling technology
– Tablet input– Facilitation of student work
• RULE funding…
Vision• Unified sections• Dedicated lecture time to active learning, group work• Incorporation of tablets for transmission of student work• “Real-time” faculty feedback, criticism
![Page 5: Improving Active Learning and Instant Feedback in an Introductory Engineering Course Caleb H. Farny Sean B. Andersson Dept of Mechanical Engineering BU.](https://reader037.fdocuments.net/reader037/viewer/2022110319/56649c3a5503460f948e323c/html5/thumbnails/5.jpg)
“Lecture”
• 4-person groups + tablet1. Presentation of new concepts (15 min)2. Example problem on new concept (15 min)– Feedback from instructional team– Wireless submission of group work instructor
3. Student-led presentation of problem solution– Instructor facilitated– Compare, contrast multiple methods, common
problems• Work posted online after lecture

Logistics• Instructional team: – Faculty instructor– Graduate Teaching Fellow (GTF)– Undergraduate Learning Assistant(s) (LA)
• Active talking: 2 hours vs 30 min– Complexities reserved for problem discussion
• Technology: iPad, stylus, drawing app, Dropbox– Enabler, not focus

Evaluation• Spring 2012:
– Section A: Traditional format• 65 students, single faculty member
– 8 LEAP students• In-class examples
– Section B: “RULE” format• 56 students, 2 faculty members, GTF
– 1 LEAP student– Same in-class examples, assignments
• Comparison: – Quiz– Exam– Instructor and course outcomes
• Anecdotal observations:– Section A: Quiet working atmosphere– Section B: Audible buzz, inter-group arguments

Section comparison
• RULE section performed higher on all tests
• Exclusion of LEAP students widens the margin

Results
• Higher average scores on all in-class tests• Relative improvement based on demonstrated
aptitude level– 3.0 (B average) and below– 2.7 (B- average) and below
• Negligible measurable impact on upper-tier performance students
• Self-reported qualitative impact higher
![Page 17: Improving Active Learning and Instant Feedback in an Introductory Engineering Course Caleb H. Farny Sean B. Andersson Dept of Mechanical Engineering BU.](https://reader037.fdocuments.net/reader037/viewer/2022110319/56649c3a5503460f948e323c/html5/thumbnails/17.jpg)
Discussion
• Exposure of common mistakes• Multiple routes to correct solution• Instant feedback on acceptable method• Immediate application of new material,
reinforcement of method• Peer learning• Breaking down student-faculty barrier– GTF, LA roles– Insight into student miscomprehension

Difficulties• Drawing on iPad• Group dynamics in auditorium-style hall• Lecture delivery, timing
External Implementation• Technology aspect a minimal issue• Focus on group work• Higher-level course requires more discourse• Focus on problem definition, solution strategy
