Diary of a Teacher is a spoken diary of my experiences in education to date. I record short eps about everything from report writing to reflective practice. I share honest reflections from the classroom, lessons I've learned the hard way, and insights from educational research that shape how I teach.

4: Do later start times actually make a difference to student outcomes?

After finishing a fascintating book called Why We Sleep by Prof. Matt Walker, I found myself trying to help a student get started on her exam revision in a visual arts cover lesson. She tells me she's had 4 hours sleep because she went to bed at midnight but had to set an alarm for 4am to finish an English task due that day. She isn't very hopeful that the revision will stick, and neither am I. In this episode, I provide no final answers but enjoy having a good chat about the science of sleep, and how good sleep does seem to improve student outcomes. Literature etc. I consulted for this episode includes: Wahlstrom, K., Dretzke, B., Gordon, M., Peterson, K., Edwards, K., & Gdula, J. (2014). Examining the impact of later school start times on the health and academic performance of high school students: A multi-site study.

3: Managing Cognitive Load in the Classroom

It has been a six-lesson day and there are still lots of jobs to do, but it's time for an afternoon of professional development. This time you'll be learning about managing student cognitive load. You hope to high heaven that the facilitator doesn't fall victim to the ultimate irony... cognitively overloading you! In this episode, I talk about cognitive load theory, and how I went about addressing it in professional development. Literature etc. I consulted for this episode includes: Sweller, J. (1988). Cognitive load during problem solving: Effects on learning. Cognitive Science, 12(2), 257–285. https://doi.org/10.1207/s15516709cog1202_4 Ward, M. & Sweller, J. (1990).

2: Does Peer Instruction Actually Work?

Harvard physics Professor Eric Mazur developed Peer Instruction in the early 90s, after noticing that many of his students weren't deeply understanding concepts despite performing well on traditional exams. He wanted to explore the nuts and bolts of that discrepancy. In this episode, I talk about my dealings with Peer Instruction to date, what the research says, and some potential pitfalls. Literature etc. I consulted for this episode includes: Mazur, E. (1997). Peer instruction: A user's manual. Prentice Hall. Crouch, C. H., & Mazur, E. (2001). Peer instruction: Ten years of experience and results. American Journal of Physics, 69(9), 970–977. https://doi.org/10.1119/1.1374249 Fagen, A. P., Crouch, C. H., & Mazur, E. (2002).

How to Write Tailored Report Comments in Less Time

I've got a system for writing report comments, but it takes forever and isn't particularly efficient. Naturally, my problem-solving brain starts looking for solutions during the school holidays when we're both meant to be resting. The result? I have a system to recommend. It still allows for tailoring of comments so that each student receives the bespoke comment they deserve. But it streamlines various aspects of the process to save me time. Win win.

Why Do Teachers Move Schools?

Next year, I'll be moving to a new school. The process is bittersweet - whilst there is excitement at the prospect of learning new things, it has been hard to say goodbye to colleagues and students. As you can imagine, these last few weeks I have spoken with many colleagues and friends about the move. Everyone seems to have their own unique view on this life event, based on their experiences. So, when do teachers move schools, and why? Write to me: hello@spongeeducation.com. Visit the website: https://www.spongeeducation.com.

And if your students aren't too exhausted... like anything, you've got to have buy in if you want it to yield results. Write to me: hello@spongeeducation.com.
