While a forward (Team A) takes a shot on the goal, a midfielder (Team A) is standing in an offside position on the goal line. The midfielder does not attempt to play the ball and does not challenge the goalkeeper and other Team B players (no impact on the opponents). The ball goes directly into the goal. What is the correct decision? The referee awards a goal because the midfielder has not committed an offside offence.

A note about the Substack platform from the authors. We had several conversations about whether we wanted to write a post that was published on Substack, given Substack’s current stance on publishing pro-Nazi and racist content. We decided to write this guest post because we think alternative grading can help move the needle in a more just and equitable direction, but we nevertheless want to collectively express our discomfort with Substack for choosing to promote and platform Nazi rhetoric. Notably, one contributor to this post chose not to list their name as an author out of a moral objection to Substack’s pro-Nazi stance.

I have tried to find ways to return to the old ethos of grading, in which I would judge a student as a whole person rather than as a series of assignment transactions. But in the age of courseware, I must give this holism a name and a value and a slot in the gradebook. Fine. I call it “Slush”—a grading category that I put into the system to account for whatever the rubric, the outcomes, and their computerized rigidity cannot. Slush is my gesture at an overall assessment of student performance and growth.

There are some useful models that might be used to determine if some practices are more effective than traditional assessment models. Dawson R. Hancock out of the University of North Carolina at Charlotte, for example, explored how test anxiety and perceptions of the instructor could negatively impact achievement and motivation. When Hancock wrote that essay in 2010, most instructors were using the traditional letter and number grades, so it would be interesting to see if an instructor whose teaching materials clearly signaled their commitment to a set of alternative assessment practices might reduce the anxiety students feel in the classroom space and perhaps maintain (or even better, generate more) motivation and improved achievement markers.
If the experiments analyzed here had been conducted as randomized controlled trials of medical interventions, they may have been stopped for benefit—meaning that enrolling patients in the control condition might be discontinued because the treatment being tested was clearly more beneficial.
"Available evidence has found no link between the use of paracetamol during pregnancy and autism," the European Medicines Agency, Europe's top drug regulator, said in a statement. Paracetamol is a widely used name for acetaminophen outside the U.S.

The lesson is so simple even Ivy Leaguers should be able to understand it. In good times, investors give no thought to liquidity, because cash is plentiful and the need for it isn’t pressing. In hard times, liquidity becomes the only thing investors can think about, because cash is scarce and the need for it is desperate.
The saddest part of this sad saga is that it's deja vu all over again.

“It would be a disaster for our students to have no idea how to effectively use one of the most powerful tools that humanity has ever created,” Brown said. “AI is such a powerful tool for self-education, that we must rapidly adapt our pedagogy or be left in the dust.”
For instance, OSU said education majors could be asked to use AI to create a lesson plan, which they then will evaluate and revise. The sample assignment would require students to submit their lesson plan along with their initial AI prompt and a reflection on what they changed and how effective the generative AI was.
