The first step in working with student teams in
engineering courses is forming teams. Although there are many
issues connected to forming teams, four will be highlighted.
- Responsibility for assignment: Who should select the teams?
- Team Size:
What issues are connected with selecting the size of the student
teams?
- Team Composition: What attributes of the individuals should
be considered when composing student teams?
- Team Schedule: How might the students' schedules be considered
when forming teams? One of the most challenging tasks that
team of students faces is finding a satisfactory meeting time.
Guidelines generated through inquiry into these issues will
depend on the team's purpose, the team's duration, and the
students' maturity. Although there are no set rules for the
formation of student teams, thoughtful consideration of these
four issues will help provide a better learning experience
for the entire class.
Decision No.
1: Responsibility for Assignment
The first issue
that arises in forming teams is who should have the responsibility
for composing the teams. There are three alternatives.
- Self-selection: Students decide on
the composition of the teams.
- Instructor selection: The instructor
assigns each student to a team. An instructor might assign
teams randomly, for example, students count off to form
teams. This is quick and efficient, and ensures some heterogeneity
in the teams. Stratified random may also be used to distribute
prior skills or experiences. Or, as described below, the
instructor might elect to consider several factors more
systematically.
- Joint selection: The instructor and
students together decide on the composition of the teams.
In one model of joint selection, the instructor might
set criteria that team composition must meet, while the
students form teams that meet these criteria.
Allowing students to form their own teams helps them accept
greater responsibility for configuring their own learning
environment or becoming co-conspirators in their own learning.[2]
However, research on teams or small groups in the classroom
supports either alternative 2 or 3. For example, Feichtner
and Davis[3] report "
responses
indicated that students are more likely to have positive
experiences in classes where groups are either formed by
the instructor or by a combination of methods (e.g., one
instructor collected data on students' research interests
and then group those with similar preferences). Specifically,
in recording information concerning their worst group experience,
40 percent of the respondents noted that the groups were
formed by the students themselves, while in the best group
experience, only 22 percent reported that the students were
responsible for forming the groups." Brickell et al.
[4] presented two conclusions from their
study that also suggest superiority of the latter two alternatives.
"1. Appointed groups with a mixture of homogeneity
and heterogeneity perform better (earn higher group grades)
when compared with self-selected groups. 2. Allowing students
to select their own groups results in the poorest attitudes
about the course, their instructors, the projects, their
classmates, and other criteria." These results indicate
that the instructor must take an active role in forming
the teams.

Decision No. 2:
Team Size
| The ideal size
of the team depends on the nature and duration of the project
and the maturity of the team members. For instance, in-class
exercises requiring students to use a computer or a limited
resource may restrict the working group size to a pair. As
another example, the " shorter amount of time available,
the smaller the groups should be."[5]
In a survey of students in a number of team experiences Fiechtner
and Davis[3] found that students have the
most positive experiences and perform the best in teams ranging
in size from four to seven. Some issues related to team size
are summarized in the table below. Finding suggestions in
the literature for team sizes of three, four, or five is common.[5-7]
Team Size: Issues and Concerns
The table below summarizes issues and concerns with different
sizes of teams.
|
Smaller
Teams
|
Larger
Teams
|
| Lack diversity of opinions necessary
for a truly high-performance team. |
Lead to difficulty arranging meeting
times (many different schedules to consider). |
| Tend to be unstable over a semester—one
or two absent students make the team inoperable. |
Understanding each other and reaching
consensus becomes more difficult. |
| Considerable reduction of active participation
and learning. |
Longer time to develop a trusting/working
relationship. Often no relationship is developed. |
| Higher frustration due to lack of people
to perform assigned tasks. |
More chances of students “slacking” and
delegating their work to others in the group. |
| Lack ownership and increase isolation. |
Lack of team dialogue. Collaboration
is sacrificed. |

3: Team Composition
Teams are composed of people, with each
member contributing a unique blend of attitudes, convictions,
beliefs, skills, strengths, and weaknesses to the equation.
Some of these elements are known and others are unknowable in
advance, perhaps even to the individuals concerned. When these
human elements are mixed together, placed under pressure, and
have to work together in a concerted way, almost anything can
happen. Even a team composed of the very best people has some
probability of failure. Nonetheless, the level of heterogeneity
plays an important role in team selection by maximizing individual
contributions, which ultimately maximize the performance of
the team. Homogeneous groups (i.e., groups of individuals with
similar characteristics) get answers more quickly and with less
fuss, but the answers tend to be unimaginative. Heterogeneous
groups, while more diverse, may take more time yet generally
produce better results and are more creative in their solutions.[8]
There are several aspects to be considered in team heterogeneity.
These include but are not limited to:
- Skills (e.g., computer, writing, presentation)
- Previous academic performance
- Gender
- Ethnicity
SkillsMatching students with the same skill level
tends to generate task completion redundancy. On the other
hand, matching students with different skill levels increases
team's productivity by having a well-distributed set of tasks
and equalizing participation. Measuring skill level takes
some time but is always worth the effort.How to Measure
Skill Level? How to Measure Skill Level: You might measure
a student's skill level by conducting a short questionnaire
(for an example, see http://www.foundationcoalition.org/home/keycomponents/teamsurvey.html)
that asks students to measure their levels of expertise when
working with computers or specific software, writing a report,
or conducting a presentation. In addition, you can do several
in-class exercises in which students draw from a pot a piece
of paper outlining a specific theme (e.g., favorite animal,
most memorable trip, etc.) and talk for two or three minutes
about that topic, which can give you a sense of a student's
public speaking skills. This exercise can also be a writing
exercise, or you may ask them to write a statement of purpose.
By doing this, you will learn more about your student pool
and class composition.How to Equalize Skill Level?
Once teams with heterogeneous skill levels are created, it
is important to help all team members improve. One way is
by having students rotate roles and having members delegate
to one another specific tasks that require a certain skill
level. For example, a student with lower AutoCAD skills can
be responsible for starting the next team graphics assignment
with the assistance of the "AutoCAD expert" from
his/her team. This way, the person is learning by doing, with
guidance from the team's expert. Faculty can also help these
students by specifically assigning tasks to these less-skilled
students as individual or extra-credit assignments. Faculty
may also occasionally give a computer quiz to all team members,
but use the lowest grade as the grade for the team. This reinforces
individual accountability and encourages students to work
toward a common learning goal. However, faculty members should
address the resistance that this approach may create in advance.Previous
Academic PerformanceConsidering previous academic performance
is also an important aspect when forming teams. Avoid matching
all the experts or the academically disadvantaged together
in one team. The hope is to have the less academically advantageous
learn from those students who are considered above average.
Again, the goal is to create a well-balanced group with a
good blend of skills and learning styles.
Gender and EthnicityOther aspects worth noting are
gender and ethnicity. The issues of gender ratio and ethnic
ratio have been topics of discussion for many years. Earlier
researchers have argued that when women, or any ethnic group,
represent a small fraction of a group (i.e., less than 15
percent), the minority member status is considered a token,
and this damages general team dynamics.[9]
This earlier research suggests that isolating minority students
from other minority students or females from other females
can in fact be detrimental to the academic success of these
individuals because they can become isolated, marginalized,
or placed in stereotypical roles and not permitted to flourish.
However, later researchers have challenged this theory[10,
11, 12] by suggesting
that increasing the number of females in a group will not
necessarily lead to positive team dynamics. According to Steele[12]
, as an individual's minority status becomes more salient
in a group, there is an increase in stereotype threat. Hence,
increasing the number of women and/or underrepresented minorities
in a group could magnify stereotypes and lead to a more hostile
environment.A study at Arizona State University has shown
consistency with the second position, in which increasing
the number of females and/or minorities can lead to a less
stable environment.[13] Females and minorities
have reflected on their team arrangements. Most of them agree
that team formation should target students' abilities rather
than gender or ethnicity. Females and minorities knew that
they were placed in a team in pairs, and they also understood
why. Nonetheless, students felt that this arrangement didn't
impact their individual performances (either positively or
negatively).[13]
Moreover, underrepresented minorities and women enthusiastically
stated that they didn't feel discrimination and were treated
as equals by their peers and instructors. Their interest is
to be considered individuals with certain academic abilities,
knowledge, and personalities instead of being categorized
by their gender and/or ethnicity.

4: Team Schedule
|
Most teamwork occurs through face-to-face interaction. Therefore,
good teamwork requires effective meetings! When forming teams,
approximately 90% of the time, students express a problem
with finding a common time to meet. In most cases, finding
a meeting time outside the classroom is more a hassle and
a frustration to students than any assignment or test you
give them.Arranging meeting times depends on the size of the
team. The larger the team size, the more difficult it is to
schedule a common meeting time. One approach that helps in
scheduling meetings, necessary for team success, is to create
a meeting
schedule in which students can write the times when they
are in class and/or working and their available times to meet.
If this is done early in the semester (by the second week
of classes, when course adding and dropping period ends),
the team already commits to a common meeting time prior to
getting involved in other extracurricular commitments, which
tend to evolve a little later in the semester. This is a suggested
method for establishing a common meeting time, but other,
simpler methods could be used.
