HOMEWORK:


1.       What is the big take home message(s) from the Prezler paper.

For me, there were two big themes that I pulled out of this paper.

The first is that students in upper division courses were less likely to view clicker questions as valuable to their learning.  The authors propose that the reason was that most of the students moved into the upper division courses without having used clickers in previous courses.  The clicker questions represented change in what those students are used to.  What I take from this is that in higher-level courses, the instructor must present the students with and evidence-based rationale for using clickers in their classroom.  Also, it is important to use quicker questions that are of a higher cognitive level.

A second refers to figure 6.  These data demonstrate that in both lower and upper division courses, clickers improved performance on exams.  This was the most objective data presented in this paper and my opinion.


2.       Using the information from Caldwell’s paper, write two high quality clicker questions that will provide meaningful information about student understanding.

Question 1:
JT is a 63 year old female who presents to her physician with complaints of fatigue and shortness of breath on exertion, both of which are progressively worsening.  She reports no chest pain, cough, or peripheral swelling.  Her physical examination findings include a normal pressure, a normal and regular heart rate, and decreased radial pulses.  Her lung exam is normal.  Auscultation of her heart reveals a loud S1, no third heart sound, an opening snap, and a low pitched diastolic murmur that is heard most prominently at the apex of the heart.  An echocardiogram reveals a pressure gradient between the left atrium and ventricle of 10 cm of water.
Given the history, physical findings, and findings on echocardiogram, considered the diagnosis.  Which of the following would be the preferred treatment for this patient?
a.       Mitral valvuloplasty
b.      ACE inhibitor therapy
c.       Mitral valve surgery
d.      Aortic valve surgery

Question 2:
JT is a 53-year-old male who presents to his physician with exercise intolerance, shortness of breath on minimal exertion, and ankle swelling.  His medical history includes a diagnosis of coronary artery disease.  He had coronary artery bypass surgery 6 years ago.  His electrocardiogram shows normal sinus rhythm, a normal PR interval, and a QRS duration of 180 ms.  His most recent echocardiogram revealed an ejection fraction of 31% and a large anterior area of akinesis.
Of the following, what treatment would improve his overall survival and improve his symptoms?
a.       An implantable cardioverter-defibrillator
b.      A right ventricular pacemaker
c.       Amiodarone therapy
d.      An implantable cardioverter-defibrillator and a biventricular pacemaker

Feedback for Dr. Boyer

Thank you very much for your talk today. The information will be valuable for me. I am especially interested in Delicious and Presi and will try these out. You may find me in STEM 709.

Question for Dr. Boyer:

I teach a very short course (4 classroom sessions) called Research and Design. I don't have the time or resources to do an actual experiment in class. Are there electronic technologies available that I could use to simulate an experiment? 

Thank you!
