(&#8220;Get the pink triangles, then the hollow squares, then the green circles.&#8221;)<\/p>\n<p style=\"padding-left: 30px;\">Other times, one stranger could SHOW the other the winning path. (&#8220;Watch me go this way, now this way, now this way.&#8221;)<\/p>\n<p>Which method worked better, show or tell?<\/p>\n<p>PLOT TWIST.<\/p>\n<p>In this case, the answer <em>depended<\/em>\u00a0<em>on the complexity of the puzzle<\/em>.<\/p>\n<p style=\"padding-left: 30px;\">For simple puzzles, <em>both methods worked equally well<\/em>.<\/p>\n<p style=\"padding-left: 30px;\">For complex puzzles,\u00a0<em><strong>telling<\/strong> helped more than <strong>showing<\/strong><\/em><strong>.<\/strong><\/p>\n<p>I would have been surprised if there were a straightforward answer to the question; I am, therefore, more inclined to believe this &#8220;it depends&#8221; answer.<\/p>\n<h2>Take Two<\/h2>\n<p>This result &#8212; explaining complexity &gt; showing complexity &#8212; prompted the researchers to test a second hypothesis.<\/p>\n<p>In this case, the research details get very tricky, so I won&#8217;t go into them. But the basic idea was:<\/p>\n<p style=\"padding-left: 30px;\">Perhas both words and actions can explain <strong>concrete<\/strong> things, but<\/p>\n<p style=\"padding-left: 30px;\">Perhas words do better than actions at explaining <strong>abstract<\/strong> things.<\/p>\n<p>Sure enough, the second experiment supported that hypothesis.<\/p>\n<p>As the researchers say in their first paragraph:<\/p>\n<blockquote><p>Our findings suggest that language communicates complex concepts by directly transmitting abstract rules. In contrast, demonstrations transmit examples, requiring the learner to infer the rules.<\/p><\/blockquote>\n<p>In brief, the more abstract and complex the concept, the more important the words.<\/p>\n<h2>Teaching Implications?<\/h2>\n<p>Before we rush to reform our teaching, we should notice several key points about this study:<\/p>\n<p style=\"padding-left: 30px;\">It involved adults working with other adults, and\u00a0strangers working with strangers.<\/p>\n<p style=\"padding-left: 30px;\">The participants were not &#8212; as far as I know &#8212; teachers. That is: they have neither expertise nor training in helping others understand.<\/p>\n<p style=\"padding-left: 30px;\">The task involved (sort of) solving mazes. I&#8217;m an English teacher; my teaching &#8212; and perhaps your teaching &#8212; doesn&#8217;t focus on maze-solving like mental activity.<\/p>\n<p>In other words, because this research differs A LOT from typical classroom work, its findings might not apply precisely to classroom work.<\/p>\n<h2>Teaching Implications!!<\/h2>\n<p>That said, this study reminds me of an important lesson:<\/p>\n<p style=\"text-align: center;\">Practice. My. Words.<\/p>\n<p>That is: when I&#8217;m explaining a concept to my students for the first time, <em>I should script and rehearse my explanation carefully<\/em>.<\/p>\n<p>Now, because I&#8217;ve been teaching for a few centuries, I&#8217;m occasionally tempted to wing.<\/p>\n<p>Yes, &#8220;indirect object&#8221; is a tricky concept &#8230; but I understand it well, and I&#8217;ve explained it frequently over the years, and I&#8217;m sure I&#8217;ll do just fine&#8230;<\/p>\n<p>No, wait, stop it. This research reminds me: words\u00a0<em>really matter<\/em> for helping students understand abstractions.<\/p>\n<p>I need to get those words just right, and doing so will take time, thought, and concentraction. (Ollie Lovell emphasizes a similar idea when he writes about the importance of &#8220;bullet-proof definitions&#8221;; for instance, in\u00a0<a href=\"https:\/\/braindevs.net\/blog\/\/the-best-book-on-cognitive-load-theory-ollie-lovell-to-the-rescue\/\" target=\"_blank\" rel=\"noopener\">this book<\/a>.)<\/p>\n<p>A second point jumps out at me as well.<\/p>\n<p>This study <em>contrasts<\/em> showing and telling. Of course, most of the time we\u00a0<em>combine<\/em> showing and telling.<\/p>\n<p>As I&#8217;ve <a href=\"https:\/\/braindevs.net\/blog\/\/a-new-book-on-dual-coding-that-redefines-the-word-book\/\" target=\"_blank\" rel=\"noopener\">written before<\/a>, Oliver Caviglioli&#8217;s\u00a0<em>Dual Coding<\/em> offers a comprehensive, research-informed exploration of this complex blend.<\/p>\n<p>When I think about dual coding, I typically focus on the &#8220;showing\/drawing&#8221; half of the &#8220;dual.&#8221; This study, however, reminds me that the &#8220;telling&#8221; part is equally important &#8212; and, in the case of highly abstract concepts, might even be more important.<\/p>\n<p>&nbsp;<\/p>\n<p>In brief, in my chess classroom:<\/p>\n<p>I can simply\u00a0<em>show<\/em> my students how bishops move: that&#8217;s easy.<\/p>\n<p>But &#8220;checkmate&#8221; is complex. I should both show\u00a0<em>and tell<\/em> &#8212; and get the telling just right.<\/p>\n<hr \/>\n<p>Sumers, T. R., Ho, M. K., Hawkins, R. D., &amp; Griffiths, T. L. (2023). Show or Tell?
