4 How to teach

Peyton’s method and modifications

Peyton’s Four Step approach (1998) is the most popular and tested method of skills instruction. And most people haven’t heard of it. The steps are straight forward and easily mastered.

1. The teacher demonstrates the skill at a normal pace without any comments (“Demonstration”)
2. The teacher repeats the procedure, this time describing all necessary sub-steps (“Deconstruction”)
3. The student has to explain each sub-step while the teacher follows the student’s instructions (“Comprehension”)
4. The student performs the complete skill on his/her own (“Performance”).

The four step approach has been shown superior to standard instruction using demonstrations and repeated substeps in terms of student performance and student acceptance.  Step 3 appears to be key with much of the success related to this step.

Nikendei et al (2014) were able to expand this model to small group teaching using the following modification to ensure all students were able to perform the skill, received feedback and maintained step 3:

A – Demonstration and Deconstruction
   The Tutor performs Steps 1 and 2 of Peyton’s Four-Step Approach to all Trainees
B – Comprehension, Tutor’s Performance and Observation
   The Tutor performs Step 3 following the instructions of Trainee 1, while all other Trainees are observing
C – Comprehension, Trainee’s Performance and Observation
   Trainee 1 performs Step 3 following instructions of Trainee 2, while the other Trainees are observing
D – Tutor and Peer Feedback
   Trainee 1 receives feedback by Peer Trainees, followed by Tutor feedback
E – Circulation
   Parts C and D are repeated in turn until the last Trainee has performed Step 3 following thein structions of a Trainee
F – Completion and Conclusion
   Finally, the last Trainee performs Step 4, followed by Peer and Tutor feedback.
Using this model, the group was successful in teaching iv catheter insertion to medical students and was easy to use, maintained student interest, and was well accepted by students and instructors.

Provide detailed instructions

Giving students as much information as possible on how to perform a skill improves performance. Unfortunately, many times instructors are unable to break down the steps of a skill as they have become proficient and the skill no longer requires that level of processing.  Think about tying your shoelaces or hopping on a bike and starting to ride.  Describe the steps. Now try to perform that skill following only those steps.  Usually there are quite a few key components missing!

Developing these steps often takes significant effort; cognitive task analysis has been shown effective in both veterinary and human medicine. Using videos, descriptions and questions, the steps can be identified. Once identified, they can be better taught.

Axt et al showed that breaking down the steps of a laparoscopy procedure into a limited number of essential key steps (nodal points) improved learning and internalization of the skill. Having a list of such steps not only helps with practice in lab but with mental rehearsal.

Encourage attempts (and errors)

Instruction about the most common errors and how to avoid them improved acquisition of surgical skills. Encouraging or focusing on errors during training can improve performance, retention and transfer of procedural skills. With error-focused training, learners experience common errors, how to correct them and how to avoid them during training rather than during practice.

Choice is good

Most veterinary students will be highly intrinsically motivated to learn related skills. However, for some basic skills, motivation may be limited, particularly for those who have training as veterinary technicians. In these instances, any form of choice (station, partner, activity, form or reporting) can help improve attitudes.
