Cogsci In The Physics Classroom

” Ok, fine. But what do you actually DO?”

I get asked this a lot, so this page is for ‘THIS is what I do*’.

I’ll put it in phases, where a ‘phase’ was about a year, with a concrete example where possible. (NB: I was always an extensive user of mini-whiteboards (how to use them coming soon!) – please get a set and use them).

Phase 1 – Introduced retrieval practice

Started weekly retrieval practice with my classes. Low stakes – one question from last lesson, one from last week/month, one from a long time ago. 100% correctable.
I’d done quizzes, but adding in ‘a long time ago’ had a significant positive impact.
Continued use of mini-whiteboards.

Example:
Retrieval Practice – Mon 8th Jan              
1. Last lesson:
Explain why a charged balloon picks up a piece of paper.
2. Two weeks ago
Calculate the energy stored in a spring with a spring constant of 50N/m if it is stretched by 2mm.
3. Six weeks
Draw a free body diagram for a ball rolling across the ground after it is no longer in contact with your foot.

Phase 2Refined retrieval practice, more explicit instruction, less performance

As above… AND changed the RP questions to get deliberately get more complex/abstract/unfamiliar over time within each topic.

Made 100% of homework 100% correctable for 100% credit (because it’s about the LEARNING NOT THE GRADE).

Realised there was a lot of distraction in the actual teaching part. Used fewer anecdotes/distracting videos.

Example (over time):
Draw a free body diagram for a ball falling (ignoring air resistance). Label the forces.
Draw a free body diagram for a leaf falling from a tree at a constant velocity. Do not ignore air resistance. Label the forces.
Draw a free body diagram for you in a car on a freeway doing a steady 65mph.
Draw a free body diagram for a ball rolling across the ground after it is no longer in contact with your foot.

Phase 3 Teaching metacognition, spaced homework

As above… AND designed a one lesson introduction to the brain and learning. Did it with all my classes.
(A bit nervous doing it).

Started spaced practice by deferring homework (SLOP) until 2 weeks after we’d done it in class.

Made most AP (A level) homework is SLOP (Shed Loads Of Practice) with interspersed AP questions.

Phase 4 More teaching metacognition, talking about research

As above… AND refined the one lesson introduction to focus on attention/ distraction. Told students about the research. Graham Nuttall’s 3 things is SUPER sticky**.
(A lot braver doing it).

Continued with AP (A level) homework to SLOP. Planned for better increase in complexity/unfamiliarity of context. Required a reflection paragraph.

I learned about this from Mike Hobbiss in his ResearchED talk. Thank you.

Phase 5 Even more teaching metacognition

As above… AND honed in on attention with the Posner and Rothbart*** model of attention.
(Very bold, cogsci is important, you will learn about it) .

Explicit instruction about study strategies integrated into the curriculum.

With AP (A level) homework required a detailed reflection paragraph (I gave examples).

I learned about this from Andrew Watson’s talk at Research ED. Thank you.

I also included material about the default mode network to help students understand about why getting a low grade can be so distressing. Find out more here.

*However, I have been doing the ‘cogsci lens’ for about 8 years. I started tentatively and a little nervously (you might be feeling the same way) and over that time I’ve become bolder and more robust.

** Graham Nuttall (2007) observed that students had to interact significantly with the material AT LEAST 3 TIMES before the knew it. It’s the Rule of Three (in my class).
