Observation: Reading and understand Stem & Leaf Plots
Reflection: This is a new technique to me, and it is shown
in the course package for the math class at the Faculty of Education. When
speaking about stem and leaf plots with my associate teacher, I had a difficult
time recalling what they were used for. After reviewing it, I realized it
allows the students to see all the information in one graphic display. To
me, it seems as though it is a well thought out way to organize data in a
condensed and clear manner. This might help many students be able to understand
how to calculate things such as the mean or median averages.

on reflection: An example of how one might benefit from organizing
information in a stem and leaf plot would be like the one that was shown in the
course package. They listed different food items along with their nutritional
content (example fat). This is useful as it is something we see everywhere we look in
our society, as health and nutrition is becoming such a large part of our lives. It's an easy way for students to compare different items. It also uses various fast food items showing kids the
nutritional elements each item is composed of is not only teaching them how to
organize data as well as teaches them health and nutrition, therefore this
lesson could be cross-curricular. Being in practicum I realized how great and beneficial it is to the teacher if a topic can be used in more than one subject, and this would be a great way to do so!
I am not opposed to stem and leaf plots but I don't know of anyone who uses them. If you can get your kids to think that way I say "Go for it" but I also suggest that you may get more benefit using your time to teach other concepts.
