“It’s not that students can’t pay attention, but rather that they more readily choose not to.”
Daniel Willingham (see item #5)
“Since we don’t have our Chromebooks in front of our face, most people now interact with their, like, peers and stuff.”
A 13-year-old student in a Kansas middle school, quoted in “Beyond Phones, Schools
Rethink Tech in Class” by Natasha Singer in The New York Times, April 2, 2026
“We should be designing experiences where students are encouraged to grapple with surprise, celebrate when their predictions don’t match reality, and see revision as a natural part of learning.”
Thomas McKenna (see item #4)
“The role of the teacher must evolve from ‘sage on the stage,’ delivering knowledge from one head to the next, to something more like a coach or learning architect – someone whose focus is on building relationships, modeling critical thinking, facilitating collaboration and debate, and helping students develop the human skills (motivation, teamwork, conflict resolution) that AI cannot replace and that students will need more than ever in an AI-powered world.”
Stefan Bauschard in “AI Ends Knowledge Scarcity – Now the Classroom’s Greatest
Asset Is Human Interaction” in AI x Higher Ed, March 29, 2026
“Here is the uncomfortable truth we rarely say out loud: a shocking amount of school leadership is not about students. It is about adults. Conflict. Morale. Ego. Performance concerns. Professional jealousy. Resistance to change. Documentation. Confidentiality. Rumors. Burnout. And at some point in their career, most principals will face something more serious: a staff member who crosses a boundary, violates a policy, or makes a decision that lands in the news… Students are the moral center of the work, but adults are the operational reality.”
Megan Booth in “We’re Not Preparing Principals for the Real Job of School
Leadership” in Education Week, March 27, 2026
In this article in Education Gadfly, Robert Pondiscio salutes the current interest in high-quality instructional materials (HQIM), especially the emphasis on building knowledge. He cautions, however, that buying a good curriculum package or textbook is necessary but not sufficient. “You have to look at what it asks students to do all day,” he says. “Are students reading rich, content-heavy texts and grappling with ideas that build over time? Are lessons organized around coherent topics that accumulate knowledge, rather than disconnected skills practice? Do classroom tasks reflect what we know about how learning works – retrieval, attention to meaning, and sustained engagement with content – rather than superficial activities?”
Even if all those elements are in in the package, says Pondiscio, there’s still the fact that many teachers use curriculum materials selectively, feeling free to customize, adapt, supplement, skip, and replace lessons with low-quality material from Share My Lesson or Teachers Pay Teachers. “We have not yet built a system that reliably delivers any curriculum as intended,” he says. And that is hugely consequential because what students learn is the result of what they are really doing in classrooms.
Focusing on the quality of published curriculum, says Pondiscio, is “a bit like trying to infer children’s diet and nutrition by walking the aisles of a grocery store. The availability of healthy food is encouraging and tells you something about what is possible. It tells you very little about what children are actually eating.”
The result of all the freelancing is variation, he says: “From state to state, within districts, even across the hallway in a single school, you can encounter entirely different instructional experiences. In one, students may be reading a complex text and grappling with ideas. In the other, they may be completing activities only loosely connected to the core content. Both teachers are, technically, using the same curriculum, but in practice they have diverged.”
Pondiscio is not saying teachers should “shut up and teach the script.” If adaptations are “grounded in evidence, aligned to the curriculum’s sequence, and responsive to student needs,” that’s part of good teaching. “But the default assumption too often runs in the opposite direction,” he says: “that the curriculum is suspect and that professional judgment necessitates modifying or replacing it. A healthier norm would reverse that presumption – treating the curriculum as sound unless there is a clear, evidence-based reason to depart from it.”
Customizing curriculum does have a cost: the time it takes teachers to do it. When he was a teacher in New York City, Pondiscio remembers spending 20 to 30 hours a week “cobbling together lessons from scratch or searching for materials to ‘engage’ students, differentiate instruction, or teach content-neutral ‘skills and strategies.’” In retrospect, he says, “those hours would have been far better spent studying student work, refining my delivery, or communicating with families.” Truly good curriculum materials should liberate teachers from reinventing the wheel, “allowing them to focus on the parts of the job that matter most and that, unlike curriculum creation, only they can do.”
There is another force at work: teachers who believe high-quality, on-grade-level curriculum materials are too difficult for their students and water them down or don’t use them. “That’s not irrational or merely low expectations,” says Pondiscio. “Teachers are responding to classrooms where many students are below grade level and where the supports to bridge the gap are weak or incoherent… The onus is on publishers to include pre-unit diagnostic quizzes throughout the curriculum and on schools to use those results to design effective academic interventions.”
In sum, says Pondiscio. we are winning the intellectual debate about curriculum – there’s a growing consensus on what constitutes high-quality material. But the operational part is still a work in progress: bringing into synch “what is intended, what is designed, what is taught, and what students actually experience.” A curriculum that really works, he concludes, is when “materials are used with coherence and purpose, leadership is aligned, expectations are shared, professional development reinforces the curriculum rather than introducing competing priorities or initiatives, and teachers treat curriculum as a foundation rather than a suggestion.”
In this article in Kappan, Starr Sackstein (Mastery Portfolio) advises a middle-school teacher on the effective use of checks for understanding – for example, exit tickets, quick quizzes, hinge questions, whiteboards, thumbs, polls. The challenge is that it’s sometimes hard to discern students’ level of understanding because:
In this 4QM Teaching article, high-school teacher/authors Gary Shiffman and Jonathan Bassett suggest a way to tackle the first of four questions they suggest that history teachers ask:
(Originally titled “Sensemaking in Science”)
In this article in Educational Leadership, Thomas McKenna (Boston University’s Wheelock College of Education) says that somewhere between young children’s boundless curiosity (kids’ questions about a large mushroom they discovered on the playground) and high-school science labs, kids stop asking Why? and start asking, Will this be on the test? How can science teachers keep students’ curiosity alive?
McKenna believes this can happen by using fewer worksheets and curated materials and instead orchestrating authentic, hands-on sensemaking experiences. “The real world doesn’t come with step-by-step instructions,” he says. “We should be designing experiences where students are encouraged to grapple with surprise, celebrate when their predictions don’t match reality, and see revision as a natural part of learning.” He has ten suggestions for orchestrating such experiences:
In this article in American Educator, Daniel Willingham (University of Virgina) asks whether the time young people are spending on digital devices is making them more distractable. His surprising conclusion: spending hours a day on phones and tablets hasn’t eroded students’ attention span; they still have the ability to pay attention when they want to. What’s changed is their willingness to focus on things they consider less interesting than YouTube videos and high-energy exchanges on TikTok and other social media channels.
“It’s not that students can’t pay attention, but rather that they more readily choose not to,” says Willingham. “Digital devices prompt students to more readily conclude they are bored because all nondigital activities are unconsciously compared to entertainment on their phone, and the phone always seems more attractive.”
Another way of stating the problem: with the advent of seductively engaging digital entertainment and content, there’s been a decline in the willingness to defer gratification for rewards that are less immediate. With schoolwork, says Willingham, rewards include “the satisfaction of understanding the content, the pride of receiving a good grade, or avoiding the disapproval of teachers or family members” – not to mention longer-term outcomes like being prepared for college and careers. The trade-off is between how much students value the rewards and how long they’re willing to wait for them.
If it’s true that kids’ distractibility is a learned behavior, can it be unlearned? With a bell-to-bell cellphone ban during the school day, will the unavailability of digital stimuli for the whole school day reset students’ threshold for what is “boring”? Can teachers then recapture kids’ attention with high-quality curriculum, discussions, and tasks?

In this Harvard Gazette article, Julia Minson (Harvard Kennedy School) shares an acronym that she and her students came up with for being receptive during a contentious conversation - H E A R:
• Hedge your claims. No matter how right you think you are, recognize that there are exceptions to almost every rule and most issues are complex and multifaceted. “The goal,” says Minson, “is to show that you are engaged with the other person’s point of view, not that you have so completely rejected it as to have zero doubt about your own correctness.” Use words like sometimes, perhaps, possibly, most, and some.
• Emphasize agreement. In almost any argument, “Two people can find something to agree on,” says Minson. Use phrases like We both agree that…, I also want to… I share some of your concerns… to help highlight common ground and navigate disagreement together.
• Acknowledge other perspectives. “In most disagreements,” she says, “people make their point quickly and repeatedly. They will often interrupt their counterpart to contradict their ideas, as if the opposing argument is an annoying stinging insect to be swatted out of the air as quickly as possible.” It’s important to slow down, take the time to restate the other person’s point of view, and use phrases like I understand that you really care about… Avoid the stock phrase, I hear you, but…
• Reframe to the positive. This does double duty, says Minson, by reminding you to avoid negative words like can’t, don’t, won’t, and no and negative emotions like hate and terrible and adding positive words like great, like, andwin.
Minson adds that it’s also helpful to avoid “reasoning” words like because, therefore, and explain, and words like just, simply, merely, and only.
Keeping these in mind, Minson concludes, “enabled our research participants to express their point of view while being seen as more reasonable, thoughtful, and trustworthy, even when they were discussing some of the most inflammatory topics we could think of. It also led their counterparts to be willing to have additional conversations on these and other topics, opening the possibility of ongoing dialogue and problem-solving.
(Originally titled “Yes, Principals Can Make Time to Read”)
In this ASCD online article, Jenn David-Lang (The Main Idea) suggests four ways school leaders can fit professional reading into their extremely busy weeks:
• Stack the habit. “If you want a new habit to stick, it helps to do it right after another habit,” says David-Lang. For example, after dropping your daughter at soccer practice on Wednesday, do some professional reading in the car before driving home.
• Make it obvious and easy. Print articles that look promising, put them in a brightly colored folder, carry it around, and have it handy if a meeting is delayed or you have some unproductive wait time during the day.
• Schedule it. For example, set aside 15 minutes at a predictably quiet part of the week (Friday morning 9:45-10:00?), go to a place where you’re less likely to be interrupted, and read. “Will this time occasionally get interrupted?” asks David-Lang. “Of course. But if it’s on your schedule for 36 weeks of the school year, you’ll end up reading a lot more than if you had never scheduled any reading time in the first place.”
• Join an accountability group. You’re more likely to read if you’re a member of a group that meets at a specific time and agrees on a topic and perhaps a specific article or book chapter. Plus, you’ll get more out of the reading discussing it with like-minded colleagues.
David-Lang suggests picking an approach works for you: “One strategy. One new habit. Then watch your professional reading grow.”

In this article in Journal of Research on Educational Effectiveness, Brooks Bowden and Johanna Bernard (University of Pennsylvania) and Rebecca Davis (MDRC) report on their study of a kindergarten home reading program in a large urban school district. Teachers sent books home each weekday night and parents signed a contract agreeing to read with their children. The nature of the experiment covered three important factors:
