    Exercise
    Example
    Solution
    Learner
    Reflection
    Theory
    “Tell me and I will forget.
    Show me and I will remember.
    Involve me and I will understand.
    Step back and I will act.”
    — Chinese Proverb
    Immediate
    feedback
    Definition: Educators teach and exercise small chunks of content in short cycles. 

    They provide immediate feedback so that learners can reflect on the content and
    increase their knowledge incrementally.

    Hypotheses
    • H1 Participation: Interactive learning increases the participation of students in
    classes.
    • H2 Improved Learning: Interactive learning leads to an improved learning
    experience for students.
    • H3 Scalability: Interactive learning is scalable to large classes with 300 students.

  14. Stephan Krusche, Andreas Seitz, Jürgen Börstler, Bernd Bruegge: Interactive Learning – Increasing Student Participation through Shorter Exercise Cycles
    Evaluation
    1) Qualitative evaluation with an online survey in POM
    • July 2015 (directly after the course)
    • Goal: Find out if students improved their skills and if they are confident 

    to apply the learned concepts in future projects
    • Response rate: 223 out of 294 (76%)
    2) Quantitative evaluations in POM and PSE
    • Goal: Measure the correlation between exercise participation and final exam grade 

    using a χ2 test

  18. Stephan Krusche, Andreas Seitz, Jürgen Börstler, Bernd Bruegge: Interactive Learning – Increasing Student Participation through Shorter Exercise Cycles
    Conclusion about interactive learning
    • Tighter integration of lectures and exercises leads to interactive classes
    • Higher participation in classes than in traditional courses
    • Highly significant correlation between exercise participation and final exam grade
    • Scalable and applicable to large classes without increasing teaching effort significantly
    • Future work:
    • More studies to investigate other influencing variables
    • Apply interactive learning in online courses (MOOCs)
