A Focus on Self-Improvement

Educators often say that practice makes perfect. But what should that practice look like? Psychological research reveals that not all practice is equally useful. Mindless repetition is an inefficient way to improve any skill, and short sessions of high-quality, deliberate practice matter much more than a larger quantity of such repetition. In his recent book Peak, Anders Ericsson describes the principles of deliberate practice that research has found to be effective in improving people’s skill in fields ranging from surgery to playing the violin.
How can teachers use deliberate practice to improve what they do every day in the classroom? Drawing on Ericsson’s principles and research applying practice-based approaches to teacher education, Deans for Impact, an organization composed of leaders of programs that prepare new teachers, recently produced Practice with Purpose, a report exploring the application of deliberate practice to teaching. We identify five essential principles of improving teaching through practice:
Push beyond one’s comfort zoneWork toward well-defined, specific goalsFocus intently on practice activitiesReceive and respond to high-quality feedbackDevelop a mental model of expertise
Many teachers are already using a version of these principles for student learning—by including a homework question that students are likely to struggle with to push them beyond their comfort zone, for instance. As a high school math teacher, here’s how I try to use deliberate practice to improve my craft in the classroom.
What Should I Practice?
The first principle is to push beyond one’s comfort zone. One area of my teaching I’ve been working on is facilitating discussions—I’m much more comfortable with other aspects of my teaching routine, like managing group work, giving explicit instruction, and summarizing key ideas from a group task. Facilitating a purposeful, meaningful discussion is much harder for me, which makes it a good candidate for deliberate practice.
The second principle is to work toward well-defined, specific goals. Facilitating discussions is one possible goal, but I can find even more concrete parts of facilitating discussion to work on. Mary Kay Stein and Margaret Schwan Smith have identified selecting and sequencing student strategies as an essential aspect of a successful discussion. I can focus specifically on this one element of discussions to practice purposefully and make the most of my effort. As I improve at selecting and sequencing, I can move on to other goals—perhaps teaching students to build off of each other’s ideas. Practice continues, focused on the principles of pushing my comfort zone and focusing on specific goals.
What Does Deliberate Practice Look Like?
The third principle of deliberate practice is to focus intently on practice activities. Focus should be on quality over quantity; a short session of high-quality practice will help me improve more than intermittent efforts directed toward vague improvement. Instead of trying to improve the quality of every discussion I engage in, I can zoom in on one example each week. One tool I’ve used is the voice recorder feature on my phone. I can turn the voice recorder on for a few minutes of discussion and listen to it after class to learn how I could improve my facilitation in that moment. Every time I do this, I am surprised at how many phrases I want to take back—I’m not nearly as eloquent as I would like to think. Focused practice doesn’t necessarily mean focusing more in the moment. Instead, it means finding more ways to examine, unpack, and learn from practice.
The fourth principle is to receive and respond to high-quality feedback. This one is tough. Many teachers don’t have access to feedback on a regular basis. One advantage of the voice recorder strategy is that, if I can’t find another teacher to give me feedback, hearing myself teach allows me to give myself more useful, objective feedback. If another teacher is able to observe me, I can focus their feedback by asking them specific questions about my current goals or by asking them to observe a particular moment in class.
What Knowledge Do Teachers Need?
The final principle of deliberate practice is to develop a mental model of expertise. I don’t want to reinvent the wheel in my classroom. I’m not the only teacher trying to improve at facilitating discussions. And luckily, many of those teachers have shared their wisdom. I want to work to improve discussions in my class with a clear vision of what a great discussion looks like, the components of those great discussions, and how a discussion fits into a larger trajectory of student learning. I can do this by observing other teachers, looking to outside resources to identify new goals, and finding new perspectives on what excellent teaching looks like. Comparing my teaching with my mental model helps me to self-monitor and becomes its own source of feedback, further improving my teaching.
When I share the principles of deliberate practice with other teachers, they often tell me that these ideas are common sense. In many ways they are—the claim isn’t that they’re innovations. But it is challenging to realize the full potential of deliberate practice on a daily basis, and I have spent too much time in my career trying to improve without focusing on these principles. Coming back to them helps me improve the quality of my practice, and, in turn, the quality of my teaching.

People with depression use language differently – here’s how to Find it

From the way you move and sleep, to how you interact with people around you, depression changes just about everything. It is even noticeable in the way you speak and express yourself in writing. Sometimes this “language of depression” can have a powerful effect on others. Just consider the impact of the poetry and song lyrics of Sylvia Plath and Kurt Cobain, who both killed themselves after suffering from depression.

Scientists have long tried to pin down the exact relationship between depression and language, and technology is helping us get closer to a full picture. Our new study, published in Clinical Psychological Science, has now unveiled a class of words that can help accurately predict whether someone is suffering from depression.

Traditionally, linguistic analyses in this field have been carried out by researchers reading and taking notes. Nowadays, computerised text analysis methods allow the processing of extremely large data banks in minutes. This can help spot linguistic fea…

The Moral Logic of Survivor Guilt

If there is one thing we have learned from returning war veterans

Posted Jul 20, 2011


If there is one thing we have learned from returning war veterans - especially those of the last decade - it's that the emotional reality of the soldier at home is often at odds with that of the civilian public they left behind. And while friends and families of returning service members may be experiencing gratefulness or relief this summer, many of those they've welcomed home are likely struggling with other emotions.

High on that list of emotions is guilt. Soldiers often carry this burden home-- survivor guiltbeing perhaps the kind most familiar to us. In war, standing here rather than there can save your life but cost a buddy his. It's flukish luck, but you feel responsible. The guilt begins an endless loop of counterfactuals-thoughts that you could have or should have done otherwise, though in fact you did nothing w…
