Thank you @ievajusionyte.bsky.social for your powerful article in the @BostonGlobe on the Brown shooting and the plague of gun violence in the US.

I’m a scholar of gun violence. Not even I can process what happened at Brown. - The Boston Globe
My typical response to school shootings is to call for policy changes. But I’m afraid the task ahead is bigger than that.

A short piece on the tragedy at Brown University—and why we must refuse to accept mass school shootings as normal.

I am numb with grief and horror and rage. Brown has been my home for thirteen years. I've taught in Barus and Holley. It was an econ class.

Hug your loved ones and tell them how much they mean to you.

Impressive new RCT on professional learning/teacher beliefs/instructional practices.

It uses a team-based, theory-driven, methodologically rigorous & large scale research design to uncover core insights about increasing student engagement & learning.

Hey #econsky! I'm organizing a workshop at Brown this Spring in partnership with Eric Nielsen and Viviana Rodriguez.

The topic is educational measurement. Please submit a paper/extended abstract! We'd love to consider your work.

And please help us spread the word to folks who aren't on bluesky!

Thanks to The Learning Agenda for inviting me to give a Thought Leader talk on *Implementing* and *Scaling* Effective Teacher Coaching Programs at their annual conference.

Happy to share a few of my key takeaways.

What else is the secret sauce of sustaining effective teacher coaching programs?

That is a key question from a cost-benefit perspective. We cannot fully nail it down b/c we lack a pure control group, but we estimate that 3:1 tutoring would need to raise student achievement by at least 0.07 SD to be more cost-effective than 1:1. This is far from guaranteed based on literature.

Check out the full paper - it is a short and sweet 7 pages.

Many thanks to the good folks at Littera Education for their partnership and my amazing coauthor Ginny Lovison!

And finally, survey responses indicated that 1:1 tutoring online allowed tutors to:

4) create a space where a “kid feels special, valued, and safe to be themselves” and students “weren’t afraid to ask questions” and “weren’t afraid of being wrong.”

Tutors reported 1:1 tutoring online was more successful because they could:

2) “build a better relationship with students”

3) “move at a faster pace” because there were “less distractions” and students were not “working at different paces”

4️⃣ primary advantages of 1:1 tutoring online emerged from tutors’ open-ended responses.

Tutors commonly reported that individual tutoring allowed them to:

1) “personalize the lesson” and “customize the learning experience” so that each student “learned at his/her own pace”

My hot take - extrapolating from this study & other evidence:

Tutoring in small groups is harder in an online setting than in person.

If online tutoring is the best fit for your context, I would prioritize one-on-one.

If you want small groups, prioritize tutoring in person.

Reposted by Aaron Sojourner

What are the tradeoffs of one-on-one vs. small group (3:1) tutoring in an online setting?

We ran an RCT and surveyed tutors working in both conditions to find out.
