Make It Stick: Why spaced, interleaved practice works
In the spirit of Make It Stick, I am adding details and presenting some review of the material from before, but in a different way here, to "make it stick" in your brain :-)
In this post, I am detailing how to think of the process of learning, and how you can use your practice best to retain information.
In effect, retrieval---interrupts forgetting. (Brown et al. 37).
Finding or remembering old information is hard because our brain has forgotten the cues or connections to the information stored, not because we have lost information permanently (Brown et al. 77). So how do we help ourselves keep information at our fingertips? Struggling to find old information forces the brain to make new connections, linking old information to new information and/or modifying the information we are retrieving with new details.
For tango, the way we self-test/retrieve information, is to try moves or techniques of moving, at practicas or milongas. If it works, you know it! If it doesn't, that is also clear. In one study that Brown et al. cited, students who didn't get tested at all on information forgot 52% of what they had learned after ONE week, while students who had been tested repeatedly, only forgot 10% (Brown et al. 55). What is the takeaway here? GO DANCING!
To be most effective, retrieval must be repeated again and again, in spaced out sessions so that the recall, rather than becoming a mindless recitation, requires some cognitive effort. (Brown et al. 45)
Once you have it right, don't stop practicing/reviewing! It is easy to misremember material. Often, if you dance with someone doing it wrong, you will change your memory of the move to what they are doing. Or, someone may remember it differently, and you start to form a memory based on the other person's version (Brown et al. 116-7).
Often in tango, we say that you have to learn something at least three times to remember it well. I have heard numerous teachers repeat this information. Why does repeating the learning experience help you remember? Relearning/recalling learning makes material clearer, connects it better into cues/memory and “weakens competing routes” of cues/memory (Brown et al. 83).
Elaboration is the process of giving new material meaning by expressing it in your own words and connecting it with what you already know. (Brown et al. 22)
When you learn something new in tango, figure out how it fits into the information you already know. This creates connections in your brain that help you access the new information more readily. Find how the new move or technique fits into the big picture of your tango dancing, and you will remember the information better.
One way I help my students do this, is to present information that is closely related, but different. Each new step is connected into the material we have already learned.
For example, my advanced class is working on back paradas, leader front sacadas through the follower's back step, and single-axis turns from the follower's back step. For these three moves, there is only a slight change in the lead to produce different results (send the follower, but don't go; intersect the middle of the follower's back step; and intersect the follower's back step as close to the new landing spot as possible). When we work on them in the same class, the followers can feel the difference in the leader's moves more clearly, and the leaders can see when they have misjudged the movement (and have a backup plan in place, using one of the other options).
I often have students work together doing peer-teaching, which requires them to be able to explain what they are going in their own words.
As you cast about for a solution, retrieving related knowledge from memory, you strengthen the route to a gap in your learning even before the answer is provided to fill it and, when you do fill it, connections are made to the related material that is fresh in your mind from the effort. (Brown et al. 88)
Generation is "the act of trying to answer a question or attempting to solve a problem rather than being presented with the information or the solution is known as generation” (Brown et al. 87). If you have to generate part of the information (fill in the blank for example); you remember the information better because you had to work on retrieval more (Brown et al. 48).
Last week, I taught Tete's "famous ocho" and this week, I taught the reverse volcada that I think developed from Tete's move. I showed the class Tete's ocho, and asked, "What would happen if I moved away from the follower at this point?" Answer: the follower steps forward. "What could I do to prevent the follower from stepping?" Answer: the leader suspends the follower so that s/he can't step. "How do I need to move to get back on balance, moving line-of-dance, to exit?" Answer: [Usually] stepping behind with my left, then sidewises with my right foot, and then walking forward out of the move.
As we worked through each piece of the movement, I tried to ask a question that required thought. I can just show the move over and over, but it won't "stick" the way that requiring students to generate their own answers will. I am still working on this part, as I love to be helpful and provide answers for them :-)
Take time to think about what you’ve just learned and tie it into what you already know; figure out what you need to know to make it all fit together, or what skill you are still lacking in order to be able to do this thing (Brown et al 209). What is the big picture? What is the overarching larger context for this new information?
People who learn to extract the key ideas from new material and organize them into a mental model and connect that model to prior knowledge show an advantage in learning complex mastery. (Brown et al. 22)
After a class, you should think about/note/write down the key ideas or moves that you have learned. This helps with reflection (retrieval of recently learned info), elaboration (connecting it to what you already know) and generation (putting it in your own words as you mentally rehearse it) (Brown et al. 88).
I write detailed notes during and after a class when I study with a new teacher, or if I want to remember a pattern to teach it later. For example, if I hadn't kept a notebook during my studies with Tete in 2000 and 2001, I would never be able to teach a class of his movements from memory in 2015!
