Should Homework Be Banned Powerpoint Presentations

Any university teacher who does not harbour a painful recollection of a failed lecture is a liar. On one such occasion, I felt early on that I had lost the students entirely: those who hadn’t sunk into comatose oblivion were listless and anxious. Ungracefully, I threw myself even deeper into my PowerPoint presentation to save me from total ruin. Years later, I can still hear myself reading aloud the bullet points from the overhead and see myself turning around to the students to sell these points to them.

Luckily, I have no recollection of what the students thought of it, but my most painful memory is the experience of boring myself. When that happens, it is time to change one’s ways. That’s why I’ve led a move to ban PowerPoint from lectures.

There are a host of possible reasons for a lecture going wrong: a badly planned course, inadequate preparation, feeling uninspired on the day, disengaged students, a crowd that’s too big, a poorly designed auditorium. To this bulleted list of catastrophes comes PowerPoint.

The physical face-to-face lecture is potentially a complex and open event where the students, the readings, the lecturer and a case-based or theoretical problem interact. A PowerPoint presentation locks the lecture into a course that disregards any input other than the lecturer’s own idea of the lecture conceived the day before. It cuts off the possibility of improvisation and deviation, and the chance to adapt to student input without veering off course.

This is usually what makes such presentations so painfully boring: while it quickly becomes evident to the audience where the presenter is going, he or she has to walk through all the points, while the audience dreams that the next slide might be more interesting.

Not fit for teachers

Yet, to be interesting and relevant in a lecture, teachers need to ask questions and experiment, not provide solutions and results. Unfortunately, PowerPoint is designed to provide just that. Originally for Macintosh, the company that designed it was bought by Microsoft. After its launch the software was increasingly targeted at business professionals, especially consultants and busy salespeople.

But during the 1990s it was adopted more generally by corporations as it became part of the Microsoft Office package, which explains the executive summaries, one-liners, ubiquitous “deliverables” and action plans. Its way into academia was then helped by the increased pressure on faculties to deliver more teaching and the increased demand from a more diverse student population to be more concretely guided through the jungle of knowledge.

As it turns out, PowerPoint has not empowered academia. The basic problem is that a lecturer isn’t intended to be selling bullet point knowledge to students, rather they should be making the students encounter problems. Such a learning process is slow and arduous, and cannot be summed up neatly. PowerPoint produces stupidity, which is why some, such as American statistician Edward Tufte have said it is “evil”.

Of course, new presentation technologies like Prezi, SlideRocket or Impress add a lot of new features and 3D animation, yet I’d argue they only make things worse. A moot point doesn’t become relevant by moving in mysterious ways. The truth is that PowerPoints actually are hard to follow and if you miss one point you are often lost.

On top of this comes the ambivalence of what’s in those bullet points. In my presentations, the text on slides are really just my private and often hastily written down thoughts. Unlike my other published and peer-reviewed work, no one has seen or criticised my PowerPoints. Yet the students perceive my bullet points as authoritative, and they would often quote them in their assignments instead of going through the toll of finding the meaningful points in the real texts from the course.

Free from PowerPoint

While successfully banning Facebook and other use of social media in our masters programme in philosophy and business at Copenhagen Business School, we have also recently banned teachers using PowerPoint. Here we are in sync with the US armed forces, where Brigadier-General Herbert McMaster banned it because it was regarded as a poor tool for decision-making. We couldn’t agree more, although we do allow lecturers to use it to show images and videos as well as quotes from primary authors.

Apart from that, the teachers write with chalk on the blackboard (or markers on the whiteboard). Contrary to what PowerPoint allows, the chalk and blackboard enable us to note down points from the students alongside and connected to the points that we ourselves develop. Most universities are actually defending Microsoft’s monopoly by stealth, by architecturally letting the projector and PowerPoint take precedence over other technologies such as the blackboard.

Of course, lifting the uneasy burden of PowerPoint off the teacher’s shoulders places higher demands on planning. Yet, while at our masters programme we as teachers have a clear plan in terms of what should happen every minute of the lecture, the exact content should remain variable and open-ended. In order to support interaction, the students sit with visible nameplates, also introduced in the first lecture of the course last year. This way less active students can be called upon to expand on the concepts and connections growing on the blackboard, either from their seat or by coming to write on it.

In all my years of using PowerPoint the traditional way, students unvaryingly complained about not getting the slides in advance of the lecture. Today, the students don’t mention the lack of PowerPoints at all – they only call for a better order on my blackboard. They are right, but contrary to the rigid order of a PowerPoint presentation, the blackboard order can actually be improved in real time.

Without the temptation of PowerPoint, lecturers have nothing but the students to fall back on. That seems like a much more promising turn of events.

The Conversation

How long is your child’s workweek? Thirty hours? Forty? Would it surprise you to learn that some elementary school kids have workweeks comparable to adults’ schedules? For most children, mandatory homework assignments push their workweek far beyond the school day and deep into what any other laborers would consider overtime. Even without sports or music or other school-sponsored extracurriculars, the daily homework slog keeps many students on the clock as long as lawyers, teachers, medical residents, truck drivers and other overworked adults. Is it any wonder that,deprived of the labor protections that we provide adults, our kids are suffering an epidemic of disengagement, anxiety and depression?

With my youngest child just months away from finishing high school, I’m remembering all the needless misery and missed opportunities all three of my kids suffered because of their endless assignments. When my daughters were in middle school, I would urge them into bed before midnight and then find them clandestinely studying under the covers with a flashlight. We cut back on their activities but still found ourselves stuck in a system on overdrive, returning home from hectic days at 6 p.m. only to face hours more of homework. Now, even as a senior with a moderate course load, my son, Zak, has spent many weekends studying, finding little time for the exercise and fresh air essential to his well-being. Week after week, and without any extracurriculars, Zak logs a lot more than the 40 hours adults traditionally work each week — and with no recognition from his “bosses” that it’s too much. I can’t count the number of shared evenings, weekend outings and dinners that our family has missed and will never get back.

How much after-school time should our schools really own?

In the midst of the madness last fall, Zak said to me, “I feel like I’m working towards my death. The constant demands on my time since 5th grade are just going to continue through graduation, into college, and then into my job. It’s like I’m on an endless treadmill with no time for living.”

My spirit crumbled along with his.

Like Zak, many people are now questioning the point of putting so much demand on children and teens that they become thinly stretched and overworked. Studies have long shown that there is no academic benefit to high school homework that consumes more than a modest number of hours each week. In a study of high schoolers conducted by the Organization for Economic Cooperation and Development (OECD), researchers concluded that “after around four hours of homework per week, the additional time invested in homework has a negligible impact on performance.”

In elementary school, where we often assign overtime even to the youngest children, studies have shown there’s no academic benefit to any amount of homework at all.

Our unquestioned acceptance of homework also flies in the face of all we know about human health, brain function and learning. Brain scientists know that rest and exercise are essential to good health and real learning. Even top adult professionals in specialized fields take care to limit their work to concentrated periods of focus. A landmark study of how humans develop expertise found that elite musicians, scientists and athletes do their most productive work only about four hours per day.

Yet we continue to overwork our children, depriving them of the chance to cultivate health and learn deeply, burdening them with an imbalance of sedentary, academic tasks. American high school students, in fact, do more homework each week than their peers in the average country in the OECD, a 2014 report found.

It’s time for an uprising.

Already, small rebellions are starting. High schools in Ridgewood, N.J., and Fairfax County, Va., among others, have banned homework over school breaks. The entire second grade at Taylor Elementary School in Arlington, Va., abolished homework this academic year. Burton Valley Elementary School in Lafayette, Calif., has eliminated homework in grades K through 4. Henry West Laboratory School, a public K-8 school in Coral Gables, Fla., eliminated mandatory, graded homework for optional assignments. One Lexington, Mass., elementary school is piloting a homework-free year, replacing it with reading for pleasure.

Across the Atlantic, students in Spain launched a national strike against excessive assignments in November. And a second-grade teacher in Texas, made headlines this fall when she quit sending home extra work, instead urging families to “spend your evenings doing things that are proven to correlate with student success. Eat dinner as a family, read together, play outside and get your child to bed early.”

It is time that we call loudly for a clear and simple change: a workweek limit for children, counting time on the clock before and after the final bell. Why should schools extend their authority far beyond the boundaries of campus, dictating activities in our homes in the hours that belong to families? An all-out ban on after-school assignments would be optimal. Short of that, we can at least sensibly agree on a cap limiting kids to a 40-hour workweek — and fewer hours for younger children.

Resistance even to this reasonable limit will be rife. Mike Miller, an English teacher at Thomas Jefferson High School for Science and Technology in Alexandria, Va., found this out firsthand when he spearheaded a homework committee to rethink the usual approach. He had read the education research and found a forgotten policy on the county books limiting homework to two hours a night, total, including all classes. “I thought it would be a slam dunk” to put the two-hour cap firmly in place, Miller said.

But immediately, people started balking. “There was a lot of fear in the community,” Miller said. “It’s like jumping off a high dive with your kids’ future. If we reduce homework to two hours or less, is my kid really going to be okay?” In the end, the committee only agreed to a homework ban over school breaks.

Miller’s response is a great model for us all. He decided to limit assignments in his own class to 20 minutes a night (the most allowed for a student with six classes to hit the two-hour max). His students didn’t suddenly fail. Their test scores remained stable. And they started using their more breathable schedule to do more creative, thoughtful work.

That’s the way we will get to a sane work schedule for kids: by simultaneously pursuing changes big and small. Even as we collaboratively press for policy changes at the district or individual school level, all teachers can act now, as individuals, to ease the strain on overworked kids.

As parents and students, we can also organize to make homework the exception rather than the rule. We can insist that every family, teacher and student be allowed to opt out of assignments without penalty to make room for important activities, and we can seek changes that shift practice exercises and assignments into the actual school day.

We’ll know our work is done only when Zak and every other child can clock out, eat dinner, sleep well and stay healthy — the very things needed to engage and learn deeply. That’s the basic standard the law applies to working adults. Let’s do the same for our kids.
