Instructor Insights

Below, Edgar Blanco describes various aspects of how he taught ESD.S43 Green Supply Chain Management.

Collaborating with Invited Speakers

Several class sessions feature invited speakers. These presentations afford students opportunities to ask questions about how the concepts we discuss in class operate in the real world. In general, inviting a guest speaker, who may not be an educator, to address a class is always a high-risk situation.

I address this by only inviting people I have previously seen speak. I also ask them to send me their slides one week before their sessions. I review their slides to make sure they will address the topics I need them to cover. We meet before their sessions for about 30 minutes to run through their slides together. After their presentations, we debrief. I invite them for lunch or coffee and we talk about what worked well in their presentations, and what could be improved.

Providing this kind of support for guest speakers helps ensure that their sessions are successful and that they feel welcomed and valued.

Engaging Students in Classroom Discussions

ESD.S43 is a discussion-based course. One strategy I use for engaging students in classroom discussions is to ask provocative questions. I also make claims that force students to react and to emerge from their comfort zones. For example, in response to a student’s comment, I might say something like, “So what you mean is this...” and then frame his or her comment in an extreme way. This always gets students talking! It stirs up their passions.

It’s also my personality to bring a lot of energy to the classroom: I move my hands, I walk around the classroom, and I look at students very intently when they speak. This makes the discussions personal and engaging.

Addressing the Challenges Students Face in Completing Team Projects

Students have many demands on their time. When they’re working on a team project—like they do in this class—dealing with time constraints and equitably distributing work become even more pronounced challenges. I proactively address this issue by dividing the team project into smaller assignments—such that there is not a big deliverable at the end of the term.

All of the deliverables are things groups should be able to complete in four hours of very productive teamwork. I also never make the deliverable more than two pages or a few slides. I want teams to condense their thoughts and to have something they can all agree on in the timespan of one afternoon.

Of course, before that afternoon, each of them might spend different amounts of time thinking about the assignment, but they know that they are going to come together to create a concrete deliverable that they can commit to completing. So, in some ways, I intentionally restrict the amount of output I expect from them.

I also meet with each team three times each semester to find out how their project is going and how they are collaborating as a team. I specifically consider the depth to which each of the two students is responding to my questions about the project. This helps me gauge if one of the students isn't contributing enough to the team and presents me with an opportunity to preemptively address problems.

If I perceive problems, I reach out to the team members separately. I also make it a point to direct questions during presentations to the student who is not contributing sufficiently.

I try to make it clear that students should come to me if they’re having problems in their teams. I also am very open with them about the fact that conflict within teams is normal and is something we can address.

Developing the Case Studies

Students examine case studies in this class. These case studies reflect over five years of research completed here at the MIT Center for Transportation & Logistics. As part of this research, we worked with many companies. I had the opportunity to meet with leaders from these companies who were trying to implement sustainability initiatives. I learned first-hand about the struggles they encountered in this area.

I built the case studies—and the course—around these technical, strategical, and tactical challenges. Our hope is that the case studies will expose students to the dilemmas they will encounter in their professional environments.

Rewards for Educators

Courses like this one require a lot of time and effort on the part of the instructor. But it’s worth it! I’m always surprised and delighted by the insights students bring to the discussions. Even if I were to teach this class three years in a row, I would gain new perspectives during each offering.

I also benefit professionally from teaching this course, because students’ team projects inform my research. They study a sector in industry deeply and present their findings to the class. I learn what’s going on in these industries from these presentations. It helps to keep my understanding current. Sometimes students bring expertise in a certain area that expands my understanding of the field. As an instructor, I not only give to them, but they teach me, as well. This is one reason I continue to teach the course.

Improving the Course

There are two important changes that are going to happen in this class. One is that I am writing a book that will become the textbook for the course. The other involves rethinking the team project.

I am considering having all the students examine one company—or perhaps different companies, but within one sector. I’m also considering providing students with a choice between two sectors, such as consumer apparel and oil. I’m considering these changes because over time I’ve noticed that companies move at different speeds when it comes to sustainability. Some companies offer bigger opportunities for learning. I want students to spend more time thinking about these particular companies. I want to make sure a good mix of companies that are making great strides and those that are moving more slowly are both represented in the class.
