Geoff’s Longform Math Education Miniseries

I’ve done a lot of longform blogging. I call them “mini-series” where I do a deep dive into a particular aspect of math instruction.

Necessary Conditions

My book about math instruction and accompanying card sets for professional development use.

Feedback from Geoff’s Professional Development

“THANK YOU for helping to make teaching math more relevant and helping me feel at ease because I still suck at math but will always continue to learn all I can so as to reach out to more students to help them love math too!”

— Secondary Teacher, Idaho

“The resources provided were very helpful and easily applicable! There were several opportunities for participation and conversation that were non-threatening and reflective!”

— MS Teacher, Michigan

    Part 2: Establishing Common and Specific Outcomes

    This is Part 2 of a mini-series on a rubric masterclass. Be sure to check out the Intro post and subsequent posts. We’ve spent the last 5+ years in the math education community advocating for teachers and students to have a growth mindset. We tell students that they can and, in fact, do continue to…

    A Rubric Masterclass Part 1: Selecting Rubric Worthy Tasks

    This is Part 1 of a mini-series on rubrics. Be sure to check out the Intro post and subsequent posts. It took me a while to figure out the whole rubric game. I’ll admit, I was relatively anti-rubric in the middle of my career. Maybe that’s because I wasn’t shown how to construct one. Maybe…

    A Rubric Masterclass

    This blog post introduces a new mini-series from Emergent Math: A Rubric Masterclass. Be sure to check out Geoff’s previous mini-series: Routines, Lessons, Problems, and Projects and Your Math Syllabus Boot Camp. The past two summers I’ve created Emergent Math “miniseries”.

  • Preparing for a Post-SAT World

    Preparing for a Post-SAT World

    Over the past year many universities made the SAT or ACT optional for college applications. Students could opt to submit their test scores or bypass taking the test entirely. This was spurred in part by the fact that COVID screwed up any kind of reliability (such as it was) of standardized test. At some higher…

    Interest in a Virtual Math Portfolio Assessment Cohort for 2021-2022

    (Update 5/25/21: The window for the interest form is closed. However, be sure to follow this blog for updates on the cohort as well as other assessment commentary.) The tl;dr version: I’m seeking secondary teachers interested in designing and implementing a portfolio system of assessment in their class. Interest form link below. I’m currently wrapping…

  • Pastoral Care for Pre-Service Teachers

    Pastoral Care for Pre-Service Teachers

    Schools and teachers have no incentives to foster a nurturing atmosphere for student teachers. Unless the school expects to hire the student teacher, there’s no inherent reason for a school to particularly care whether or not the student teacher makes education a lifelong passion or if they burn out and never even enter the profession.…

    Implicit Bias and the NFL Draft: Are Teams Under Drafting Non-White Quarterbacks?

    The 2021 NFL Draft is next week. And, as is often the case, quarterbacks are expected to be drafted highly and dominate the narrative. In a game with 22 starters (plus kickers and punters!) quarterbacks routinely dominate the top selections of the NFL Draft. And it makes sense. If you land a quality quarterback, you’re…

    “Nathan For You” is here to fix businesses, rate of work problems

    “Nathan For You” is a docu-series on Comedy Central (episodes available on Hulu) in which comedian and Canadian good-grades-getter Nathan Fielder “fixes” business by suggesting out of the box ideas to bring in new customers. These ideas includes amping up the scariness of a haunted house by telling the attendees they’ve contracted a fatal airborne…
