The scope of this Journal includes “the development and
dissemination of knowledge [particularly to] coalesce the design
and problem solving skills of engineering with medical and
biological sciences.” The subject this paper will address is “the
value of the use of teams in the engineering design process to
solve problems”. First let’s address the value of the engineering
design process vs. the scientific method in biomedical research.
In the scientific method, the standard to use in biomedical
research, a hypothesis is generated as a potential answer to an
important question. An experiment is set up and carried out to
prove or disprove the hypotheses. The results are looked at in
terms of how they compare and follow from previous studies,
what are the ramifications related to the original question and
what needs to be examined next; further test the hypothesis or
test a different hypothesis.
For the engineering design process, instead of a question
there is a problem or need. Instead of a hypothesis there is a
design constraint(s) of what the solution has to be able to do.
Experiments are done to determine if the solution meets the
design constraint(s), which is similar to testing a hypothesis;
in fact a design constraint can be written as a hypothesis. The
big difference is that design constraints are quantitative and
hypotheses are typically not. Also hypotheses are typically proven
or not proven based on statistics and whether something leads
to a statistically significant difference. A statistical difference,
however, does not mean the difference is significant enough to
matter; with hypotheses also not normally quantifying how big
a difference is required. Essentially, the difference between the
two is clinical significance. In the engineering design process,
implicit in the problem is that it is a significant problem.
Further, implicit in the design constraint(s) is that meeting it
will have a significant impact on the problem. Currently, medical
schools have determined one of the most important skills a
clinician should have is the ability to apply math and science to
physiological systems (to clinical medicine once they graduate);
which is the definition of bioengineering. If asked, it would
be an understanding of the scientific method (as well as math
and science) in order to choose the best treatment for a given
situation through their own interpretation of research studies.
The skill they are actually looking for is to be able to use the
engineering design process (at least the first few steps) in order
to choose a treatment that meets or exceeds the required clinical
performance constraints. This leads to the main topic of this
paper: Is doing the design process as a team beneficial? ABET
the accreditation agency for engineering requires that each
approved program prove that the students can go through the
design process plus have other skills that includes the ability to
work in multidisciplinary teams. Although little guidance is given
on what the ‘working in teams’ means or how to assess it, it most
likely comes from the environment most likely encountered in
the workplace.
A big push in education is working in teams with TBL (team
based learning) a popular model [1]. The typical structure, for
TBL, is to have reading before class, with an individual test
(in class), followed by a group test of the same material (with
immediate feedback); with both to assure a good working
knowledge of the material. This is followed by one or more
open-ended questions that are discussed and answered
(usually multiple choice) within each group and then there is
discussion between groups with emphasis on understanding
and/or resolving differences of opinions. This approach does
many things well including: making students more responsible
for their own learning; with more frequent incentives than
the normal 2-4 tests per term. It also encourages discussion
within groups and between groups to understand the correct
answer (first two tests) or possible answers (the third test).
Further, it assures that everyone in the group knows answers to
factual questions and have multiple examples where the factual
knowledge is applied; with rationale on why some choices are
better than others. In addition, it helps students to hone their
