If you believe one method of #teaching can be applied to all learning tasks, then you are wrong.

School math was originally grounded in what was needed for successfully navigating business and commerce. #math #maths #mathchat

That education is a public good is a long-forgotten reality in education policy.

Jean Lave suggests #math is qualitatively different in different settings.

The people with whom I get along the best at work tend to be Warren Zevon fans as well. The pattern has held true since the late 1980’s. Seems like I need to add it to my CV.

Theory, of course, permeates everything we do. -Stephen Jay Gould

If the trial version of your plagiarism/ AI checker cannot accurately identify text I copied off my own public blog post which has been online more than two years, I’m pretty sure it isn’t worth subscribing.

If you are a #DataDriven #educator or #leader, then you must be prepared to defend your data... that’s what we do with data... we challenge its assumptions, collection, analysis.

Why do people who are clearly quantitative thinkers and competent at computing become so apologetic and dismissive about the #math abilities? Maybe it time we seriously rethink the damage done in mathematics #education. #mathchat #maths

Jean Lave described how “success in school math” does not predict “success using math in real life.” #math #maths #edchat #mathchat

Any one else bothered by 36 students in a kindergarten class?

The work of educating is tiring, but exhilarating. One ends the day ready for the next. The work of schooling, with its pointless mandates, drawing energy from what matters, listening to droning chatter about “what matters” when all now it doesn’t... that causes burnout.

Doubt is an uncomfortable condition, but certainty is a ridiculous one. -Voltaire

“Solve real-world problems in the video game!” OK... solve the problems the programmers put into the game... solve simulations of real-world... solve problems within the micro world of the platform... these complement, but are not Authentic Learning. #edtech #edchat #education

Without #students, #classrooms are empty-physically, culturally, contextually, pedagogically. The idea one can meaningfully plan a class before meeting the students seems disingenuous.

I added some cryptic items to my “to do” list last evening at about 6:30 PM yesterday. I have no idea what I’m supposed to do. How long do I wait until I just scratch it off?

A post on instruction rediscovered from a piece I wrote about 10 years age:

Human #learning is largely about making meaning, which is very difficult to capture and measure, so it is ignored in #data. Too bad our #schools are missing the point of their existence.

Coding teaches students to solve one kind of problem. It’s kind of like teaching them to use a hammer.

I am starting to get very interested in “cheapest places to retire” links that show up in my feed.
