Conclusion
Motivation
• CSU Long Beach
– 36,000 students, many first-generation, low-income
– STEM Gateway for Long Beach
– 90,000 applied for 5,000 spots.
CSU Long Beach Physics
• 11 TT Faculty
• 3-year average, 18 undergrad degrees / 12 MS
degrees
• UD gateway course
• APS
– Minority Bridge Program
– PhysTEC Legacy Site
Motivation for Physics
• Important to get it right!
– Better careers for students
– Special skills, better problems
• Existence and justification.
– Recruit physics majors from introductory physics
– Double majors
– If we don’t, who will?
• We have a successful course F2F … export it.
Existing Course
• Physics for Scientists and Engineers (Mechanics)
• Not a “bottleneck” … an “accelerant”.
Engineering a Curriculum
•
•
•
•
•
•
Matter and Interactions
Physics the way physicists do it
Formal reasoning
Derive results, then apply
Physical Problem Solving
Momentum / Energy / L
Engineering a Pedagogy
•
•
•
•
•
Large lecture format: Hall of Science
I>Clicker
Cooperative
Interactive
Engaging
Honors Sections
• Support high performing students
• SCALE-UP classrooms, both 151 and 152
Long Beach Register, 2/5/14
Engineering Student Support
• Learning Assistants “Undergrad TA’s”
…but…
• Homework should be teaching physics
• 36% of exam performance “explained” by
homework (correlations, per student)
• Strengthen correlation exam <-> homework?
Koondis.com
• Zvonimir Hlousek,
…and me.
• CO incubation project.

Social Homework / Koondis.com
• Async / Groups / Roles / Rotation / Any Content
• Social Media overlay / “like” “thanks”
Instructor Workflow
• Assign groups automatically (10 min,
presemester)
• Rotate “roles” week to week
– Custom: Director, Investigator, Executive, Skeptic
• Assign problem to group (5 min)
• Grading posts, likes, thanks -> grades (5 min)
• 600 students in 10 courses now (lower / upper
division, lecture, laboratory)
Instructor Feedback
Teamwork: Social Homework
• Asynchronous teams (Kisiel NARST 2013)
PHYS 151 Fall 2013
CONNECTED TO UNIVERSITY
HELPED CONFIDENCE
ENCOURAGED EFFORT
MORE FEEDBACK
EASY TO USE
HELPFUL FOR PROBLEM

Accidental Experiment
• Spring 2012 –> Spring 2013, add SHW
• Correlations … significant at p<10^(-4)

• Homework (finally) helps exam performance.
Mechanisms?
• Grit: Duckworth … “how is failure dealt with”
• Normalizing and metacognition
– Everyone sees everyone’s work
– Everyone is good at something
– Best students struggle
• Praise … “like” “thanks”
• Overlapping, reinforcing effects
• PER research project … why does this work?
Fully Online Mechanics
• Same Homework as Brick-and-Mortar
• Social Homework to support problem solving
• Social Homework: collaborate in experiment
design
• Social Homework: portion of exams
• “GLUE”
Laboratory: Authentic STEM
Social Homework Groups Design Experiments
“Tracker” used to perform measurements
Experiments independently verified / groups
Groups decide / construct their own meaning
Ph.D. – level scientist required to judge

Online Laboratory
• 3-week cycle:
– Propose experiment (in group), RFP
– Experiment performed
– Results confirmed
• Requires a Professor – by design
• 60 seats so far, 100 in Spring 2015
• Three sections worth of capacity relieved (24
lab sections now, M-F 7am-10pm)
CSU CO Redesign Project
•
•
•
•
•
•
“Social Homework” is a “Proven Practice”
Fall 2014, redesign courses to use tool
Run course with Koondis in Spring
3 units (at replacement rate, or $$$)
Department chairs will approve “RFP”.
This year, CO pays all student fees ($35 /
student) … ANYONE in CSU who adopts.
Conclusion
• Social Homework: MOOC Glue
• Social Homework: Experiment as Social
Activity
• Students depend on each other
• CourseCraft: positive
interdependence
