“After decades of playing cat-and-mouse with academic dishonesty, we’ve reached an inflection point. Generative AI has disrupted our assumptions about authorship, originality, and the very nature of learning itself.”
Michael Wagner (see item #3)
“The greatest risk posed by large language models isn’t cheating but the encouragement of metacognitive laziness, an over-reliance that atrophies students’ ability to think critically.”
Michael Wagner (ibid.)
“What really matters is what happens inside the learner’s head.”
Derek Müller (see item #9)
“Greater stores of knowledge in long-term memory ease cognitive load and make it easier for new knowledge to stick.”
Holly Korbey (see item #2)
“Not every math teacher sees themselves as a language teacher, but they are.”
Holly Korbey (ibid.)
“At a crucial time in their lives, boys are increasingly cared for by women, especially the many boys whose fathers aren’t a regular presence.”
Claire Cain Miller (see item #6)
“Success is not about dramatic transformations. It is about the small, consistent choices you make every day.”
Mary Kelly (see item #7)
“What is the best way to measure a school’s quality?” asks Lynn Olson in this FutureEd report. This question has been debated by parents, educators, employers, researchers, and policymakers for decades. Current models for evaluating K-12 schools, including state A B C D F ratings and U.S. News and World Report scores, don’t capture many key aspects of school quality, said leaders at ResearchEd and Keystone Policy Center. They decided to “start from scratch” and commissioned Olson to create a new measurement model for assessing the performance of schools.
Olson reviewed the history of research on effective schools, creating a Venn diagram of the factors cited in major research reports:
- Rates of college attendance and completion, career training, military enlistment.
“Just having a richer set of school quality metrics isn’t enough,” Olson concludes. “Schools also need help in using the data to get better, whether they’re low-performing schools targeted by policymakers for improvement, or good schools working to become great schools. That requires coaching educators to understand school data and the steps needed to improve specific indicators. And it requires leadership at the school building level.”
Olson is not optimistic that there will be leadership from Washington for school improvement, and suggests four guidelines for states to build and implement better measurement models:
“Math Needs Knowledge Building, Too” by Holly Korbey in Education Gadfly, July 24, 2025
“After decades of playing cat-and-mouse with academic dishonesty, we’ve reached an
inflection point,” says Michael Wagner in The Augmented Educator. “Generative AI has disrupted our assumptions about authorship, originality, and the very nature of learning itself.” Attempts to detect students’ chatbot-created writing have only about a 40 percent success rate, he says, and English learners and neurodivergent students have the biggest chance of being falsely accused of cheating.
“The failure of detection,” says Wagner, “forces us to confront a more fundamental question: “What does authorship mean when AI can generate sophisticated text on demand? The traditional model assumes a solitary human author responsible for every word on the page. But this assumption no longer holds in an era where AI serves as a powerful thought partner for brainstorming, research, and revision.” The question is no longer Did you write this? but How did you write this? with students being transparent about who did what.
In our new hybrid era, teachers need to assign essays and projects that promote deeper learning and tap into personal experience, local context, and current events. Teachers also need to assess students’ work at every stage, giving feedback on outlines, drafts, revision logs, and students’ reflections on their evolving thinking. For final assessments, oral examinations have great advantages. “Through live, unscripted dialogue,” says Wagner, “instructors can probe for genuine comprehension, moving beyond surface recall to evaluate analysis, synthesis, and evaluation.” For students with speech and hearing differences and anxiety issues, portfolios are a viable alternative.
“The greatest risk posed by large language models,” says Wagner, “isn’t cheating but the encouragement of metacognitive laziness, an over-reliance that atrophies students’ ability to think critically.” But that doesn’t mean banning AI; it suggests a return to the Socratic classroom, with students asking chatbots the right questions, probing their own assumptions, demanding evidence, exploring alternative viewpoints, tracing implications, and critically interrogating the responses.
In this learning dynamic, says Wagner, “the act of questioning becomes the primary learning activity, forcing the deep, reflective thinking that marks genuine education. This solves the cheating problem by redefining the assignment into something AI cannot do alone: critically evaluate its own outputs and synthesize the results of human-led inquiry.” In short, students need to be taught not to avoid AI but to use it as one part of their intellectual toolkit.
In this Research in Higher Education article, Julie Park (University of Maryland/ College Park) and nine colleagues report on their study of 615,557 college recommendation letters written by high-school counselors, focusing on the length and content of letters and students’ race, ethnicity, socioeconomic status, test scores, and extracurricular activities.
Recommendation letters are important for students applying to selective colleges, providing admissions officers important details as they decide among students with top-notch grades and SAT/ACT scores. “Letters submitted by counselors,” say Park et al., “provide a unique vantage point since they compare students to a broader range of their peers and/or the student body as a whole, versus teachers, who generally compare students to other students in their classes.”
How were the researchers able to look at so many recommendation letters? By getting access to those submitted via the Common Application portal (2018-19 and 2019-20) and using natural language AI processing. Here are the main findings:
In this American Educational Research Journal article, researcher/consultant Roy McKenzie and Elaine Allensworth (University of Chicago Consortium on School Research) report on their study on the grades different Chicago Public School teachers gave 9th graders, the impact teachers had on students’ course grades in the same subject in 10th grade and subsequently. The researchers note that during the study (2011-2019) CPS policy was that “teachers shall exercise their independent professional judgement in developing their grading practices.”
McKenzie and Allensworth looked at three variables affecting students’ math, English, science, and social studies performance in 10th grade and beyond:
• “Teachers who positively impact subsequent academic performance tend to be harder graders,” say the authors. But the study also shows that just giving low grades is not helpful. “There is a balance – expectations should be challenging but with enough support that students rise to the challenge and get good grades in the end.”

“Success is not about dramatic transformations,” says Mary Kelly in this article in Productive Leaders. “It is about the small, consistent choices you make every day.” She suggests ten “micro habits” to boost workplace success and overall wellbeing:

About the Marshall Memo
Mission and focus:
This weekly memo is designed to keep principals, teachers, superintendents, and other educators very well-informed on current research and effective practices in K-12 education. Kim Marshall, drawing on 54 years’ experience as a teacher, principal, central office administrator, writer, and consultant lightens the load of busy educators by serving as their “designated reader.”
To produce the Marshall Memo, Kim subscribes to 60 carefully-chosen publications (see list to the right), sifts through more than a hundred articles each week, and selects 5-10 that have the greatest potential to improve teaching, leadership, and learning. He then writes a brief summary of each article, pulls out several striking quotes, provides e-links to full articles when available, and e-mails the Memo to subscribers early Tuesday (there are 50 issues a year). Every week there’s a podcast and HTMI version. Artificial intelligence is not used.
Individual subscriptions are $50 for a year. Rates decline steeply for multiple readers within the same organization. See the website for these rates and how to pay by check, credit card, or purchase order.
