The (Un)grading Spectrum β€” Grow Beyond Grades Ungrading is more of a philosophy than a single model that says β€œdo this and your students will learn.” Chris Sarkonak explores ungrading as a spectrum of possibilities that moves us away from the har...

The presence of grades takes psychological safety away from students, putting them into states of anxiety or apathy, neither of which allow for learning. @csarkonak.bsky.social growbeyondgrades.org/blog/the-ung...

Start Here β€” Grow Beyond Grades

With the phrase going gradeless, we hope to express the idea of movingβ€”gradually or rapidlyβ€”away from the pernicious influence of grades, and toward more humane and effective methods of assessment and feedback. growbeyondgrades.org/start

If standard-based grading is to progress beyond the real difficulties that beset it, it must espouse curiosity over defensiveness, openness over dogmatism, empathy over insularity. @achiaravalli.bsky.social www.growbeyondgrades.org/blog/we-need...

I’ve been using it for years, along with portfolio-based grading, and it’s been great! Ss can focus on what they need and pace it out so they can actually be successful!

Our second Growth, Not Grades winner is Sharlyn Barrett πŸŽ‰

Sharlyn writes how chasing perfection β€” whether pounds on a scale or letters on a page β€” left her ready to give up. She imagines an education that values growth and self-acceptance.

Day 9 cont: worked with the 11s on what this course should look like and be about. The goal was for them to think scientifically about their experiences in school and how we can build an environment that promotes scientific thinking and learning. Ss should feel empowered, not helpless #teach180 🎒

Day 9 cont: 12s did some work at the vertical whiteboards in random groups looking at the vector nature of force. With what they already know about force and the Mu of a Shoe lab earlier, it's almost self-taught and they are doing great! #teach180 🎒

Day 8/9: I was away yesterday. Today, the 9s started on to Activity 5 of @perimeterinstitute.ca's Nature of Science resource, resources.perimeterinstitute.ca/products/the.... This is a great activity that looks at what fast radio bursts are and gets them doing some astronomy! #teach180 🎒

Day 7 cont: 12s came in to find out we were doing our 2nd lab of the year with "mu of a shoe!" Turns out many Ss are not wearing their best footwear at this time of year! Great way to intro the vector nature of force and connecting forces to motion that we only started to explore in 11 #teach180 🎒

Day 6 cont: 12s worked on @cossettej.bsky.social's passionatelycurioussci.weebly.com/blog/kinemat... and had a blast! Great conversations, recalling what they learned last year.

Students documented their observations of the video shown. One table started by saying what they saw and then we went around the room, table-by-table, getting students to add or revise observations.

Students were instructed to come up with creative explanations that they could use to tell a 5-year-old what's happening. The explanations may sound silly, but at the heart of them are three main candidates for explaining the evaporation of alcohol from the paper in the video: 1. air carried away the alcohol; 2. the alcohol dispersed across the paper so it was no longer visible; and 3. the alcohol left the paper on its own.

Day 4 cont: 11s were introduced to @eeugenia.bsky.social's ISLE approach with a thrilling video of watching paper dry! Ss learned the importance of observations and were very creative in their stories explaining what was going on. Model building and scientific thinking is so important! #teach180 🎒

Absolutely!! Grades interfere with learning and put focus on the wrong things (ie getting points instead of understanding). Teaching Ss to think about their learning, self-assess, and make meaningful plans to grow should be the conversations we are having more of! Get Ss involved in their learning!
