The "human situations" approach to teaching cardiovascular physiology yielded performance outcomes equivalent to traditional lectures. However, students new to physiology may require additional support.

Area of Science:

  • Physiology Education
  • Cardiovascular System
  • Undergraduate Science Teaching

Background:

  • Traditional didactic lectures are common in undergraduate physiology.
  • An innovative "human situations" approach was explored for teaching the cardiovascular system.
  • Student prior knowledge varied, with some having prior physiology coursework (sophisticated) and others not (naive).

Purpose of the Study:

  • To evaluate the effectiveness of a situational approach to teaching undergraduate cardiovascular physiology.
  • To compare student performance and acceptance of the situational approach versus traditional methods.
  • To identify differences in experience and outcomes between naive and sophisticated students.

Main Methods:

  • Nine didactic lectures were structured around human situations: orthostasis, blood donation, and exercise.

  • Student acceptance was measured via pre- and post-lecture questionnaires comparing expectations to experiences.
  • Student performance was assessed using standardized cardiovascular examination questions from a previous course.
  • Main Results:

    • Sophisticated students' experiences aligned with expectations, unlike naive students whose experiences fell significantly short.
    • Sophisticated students showed a preference for the situational approach over naive students.
    • No significant differences in performance scores were observed between the situational approach and traditional lectures, or between naive and sophisticated students.

    Conclusions:

    • Didactic lectures employing situational physiology achieve performance outcomes comparable to traditional methods.
    • The situational approach may present challenges for naive students, necessitating targeted support.
    • Further investigation into adapting situational learning for diverse student backgrounds is warranted.
