Saying inquiry teaching doesn't work because you struggle with it is kinda like saying meditation doesn't work because you couldn't quiet your mind. Often, the educators who dismiss inquiry-based learning seem to lack the exact skills and mindset it's designed to build.

Ontario elementary teachers can exercise judgement, but need more time to collaborate and also strengthen the consolidation portion of math learning. “Chinese and Canadian approaches to math teaching have a lot to learn from each other.” theconversation.com/chinese-…

It was a great 3-year title run, but every streak must end. Congrats to Greg (AngryJay) for making NHL94 history & cementing 🐐 status. I’ll be back to try and start a new streak. Thanks to Darrell at @nhl94dotcom for giving so much time & energy to running this every year 🙏🏽
Congrats to Angryjay93, who did something that has never been done in the history of the NHL94 world championship. Winning on both consoles. A dominating performance on Sega Genesis 16 wins, 0 loss Won the SNES final, 3 games to 2 against the reigning champion, The Professor.

Well that was fun! My mind & ❤️are full. I missed my Mathies! Thanks @OAMElearns for another great #oame2026 conference. Thx to those who joined my session. Can’t wait to bring all the new learning back to @FaywoodABC. See you all next year!

This year's @OAMElearns conference was amazing! It’s always so great to connect with & learn from math teachers, consultants, and coordinators from across Ontario. I now know more about the kindergarten play continuum! Getting to chat with @pwharris was icing on the cake 🍰

Let's dig deeper... The EEF gave the study 2 out of 5 for evidence strength due to attrition, small sample, not controlling for teacher quality, etc. The conclusions warn mixed- and ability-grouped classes about issues already known and do not call to end mixed classes.
New EEF study finds lower-attaining students are NOT harmed by ability grouping, but higher-attaining students are held back in mixed classes. Advanced students don't get enough attention in my view. What is the goal of public education? Getting all students to a minimum competency level has to be one goal. But is there not an obligation to provide an environment for students who have surpassed minimum competency to keep moving ahead? educationendowmentfoundation…

Ability-grouping advocates can’t solve the issue that plagues every jurisdiction that does it: the gross overrepresentation of marginalized groups by race, SES & disability into lower streams taught by less-qualified teachers that lead to fewer opportunities and worse outcomes.

It was a pleasure earlier this week meeting with other members of the @LDatSchool Advisory Committee. Great brainstorming about system change, resource development, pedagogy, and coalition building to support students with LD & ADHD.

Students who take notes by hand get better grades than those who use laptops, especially in STEM fields.

If education research is “weak and sloppy,” then we should be cautious about all claims of certainty. Not just the ones we don’t like. You can’t dismiss CRP, SEL, and UDL as “unproven” while treating explicit instruction and retrieval as settled science.
“In fact, there is surprisingly little hard evidence that any of these approaches, on their own, are effective in shrinking academic disparities. To do that, teachers should consider augmenting their equity initiatives with explicit instruction, regular feedback, and lots of retrieval practice, all of which have been shown to help struggling learners.” Bingo! This is the core issue. It’s the opportunity cost of investing time, resources, and money on what has yet been proven to work and not what has been proven: explicit instruction, retrieval practice, and formative assessment with feedback. Teachers, schools, and districts only have so much bandwidth and frequently it is not spent on what decades of research show work to help all students learn.

Using mini whiteboards is a great way to carry out quick formative assessments as seen here with our math partner teacher @tdsb_DSS & allows for students to think-pair-share. @Jason_To @LizBHolder @ldilworth1 @mervisalo

A really important question; how often do students need to encounter something to remember it? I first encountered this idea through Graham Nuthall's work and his estimation based on close examination of students thinking processes that students learn concepts when they encounter it three times (see passage) but it wasn't until I read the literature around varied retrieval, spacing and interleaving that I understood what was going on. Basically it's not so much the amount of times you retrieve something as the ways in which you retrieve it. So what we want is not so much rote repetition 3 times (although this has its place for certain things) so much as a kind of variation in how students retrieve knowledge. We want students to have to retrieve something in a range of different ways, across a range of different times and to apply it in a range of new ways. So when planning retrieval, the key things are: 1. Structuring learning so concepts are revisited through different activities and assessment types. 2. Ensuring retrieval occurs across distributed time intervals. 3. Creating opportunities for students to apply knowledge in novel contexts. 4. Designing assessments that require different forms of processing the same material. There is a broad consensus that varied retrieval practice enhances long-term retention significantly more than simple repetition or rereading. When students encounter material through different modalities and contexts, they develop multiple retrieval pathways to access that information.
So you literally need to forget and retrieve three times to remember, or is that just for the graphic?

The Ontario government must increase education funding & improve working conditions to address chronic staff shortages. Overcrowded classrooms without consistent teachers do not improve outcomes. We need to do better. policyalternatives.ca/news-r… peopleforeducation.ca/our-wo…

Another study which finds that differences within groups can be just as large as those between them. This one finds significant differences within high-achieving students in mathematics. Key findings: - Not all are highly motivated. - Not all have exceptional cognitive abilities. - Some may have relative weaknesses in specific skills like arithmetic fluency. Basically high-achieving students are not a uniform group. sciencedirect.com/science/ar…

Zelensky has thanked Trump, Congress, and the American people many times. But let's be clear: when Trump and Vance said that THEY are trying to help Ukraine right now, and need to be thanked for the work personally, there are reasons to wonder. 1/ THREAD
