Setting: Diagramming
activity utilizing pod groups (8 pods with 3-4 students per pod), whiteboards,
and reporting out to the whole class
Setup for the
activity: Students were instructed to work through some similar diagramming
activities in a PowerPoint slide deck prior to coming to class. We had worked
through a similar activity in class in the preceding class period. One purpose
of this activity was to emphasize the value and efficiency of sketching out
ideas on a whiteboard before trying to use a computer-aided design tool to
create a diagram. A second purpose of this activity was to give students more
practice in applying the concepts and skills.
How the activity
unfolded in the classroom: Student groups gathered around each whiteboard
(located at the pods) and discussed various options for diagramming a
relational database. I moved from one pod to another using Socratic questioning
and mini-lectures as the student groups worked through the diagramming
activity. I used the doc cam to zoom in on students' work at the whiteboards to
facilitate class discussion of concepts.
After the activity: At
the end of the class period, students groups were directed to apply the same
diagramming techniques to their 15-week client project. They were provided
about 10 minutes to get started on this activity, which they would continue
outside class.
Additional comments
from instructor: "Student feedback indicated that students were at
first a bit embarrassed about having their group work displayed and discussed
but they were becoming more comfortable with it because a) they were learning
from the whole-class discussion, b) they prefer to focus on the concepts before
trying to implement the concepts using a computer tool, c) they prefer to be
corrected in an ungraded venue rather than via graded homework, d) they value
the individual group/pod attention before the class discussion, and e) they see
other groups erasing and revising white-board content as we discuss errors as a
full class (i.e., they realize that other groups are making the same
errors)."
