That advice typically begins with a fascinating research pool.<\/p>\n<p>Here&#8217;s the story.<\/p>\n<p>Researchers present students with &#8212; say &#8212; a list of 15 words. After distraction, how many\u00a0 words do students remember? And, can we predict <em>which ones<\/em>?<\/p>\n<p>Several studies suggest a consistent answer.<\/p>\n<p style=\"padding-left: 30px;\">Students tend to remember words\u00a0<em>from the beginning of the list<\/em>. Researchers call that the &#8220;primacy&#8221; effect.<\/p>\n<p style=\"padding-left: 30px;\">And, they remember words\u00a0<em>from the end of the list<\/em>. That result gets the moniker &#8220;recency effect.&#8221;<\/p>\n<p>Going all the way back to 1962, this primacy\/recency effect has a lot of research behind it. (For a more recent study, click <a href=\"https:\/\/link.springer.com\/article\/10.3758\/MC.36.2.429\" target=\"_blank\" rel=\"noopener\">here<\/a>.)<\/p>\n<h2>Lab to Classroom<\/h2>\n<p>So, how should teachers plan our lessons based on this particular finding?<\/p>\n<p>Let&#8217;s imagine that I tell my students a <em>list of 8 instructions<\/em>. Because of the primacy\/recency effect, I suspect they&#8217;ll remember the early and late instructionst better than the ones in the middle. (Hint: maybe I should\u00a0<em>write down<\/em> a long list of instructions&#8230;)<\/p>\n<p>But: what does this effect tell us about <em>the most valuable teaching time<\/em> during a class period as a whole?<\/p>\n<p>From time to time, scholars who translate psychology research for classroom teachers make this argument:<\/p>\n<blockquote><p>The primacy\/recency effect suggests that the <strong>first several minutes<\/strong> of class, and the <strong>final several minutes<\/strong> of class, have the greatest effect on learning.<\/p><\/blockquote>\n<p>That is: For the same reason that students remember the first and last instruction from my list of 8, they&#8217;ll learn the most during the first and last minutes of class.<\/p>\n<p>Voila: a research-based answer to the question.<\/p>\n<p>I confess, however, that I myself have doubts.<\/p>\n<p>The argument says, in effect:<\/p>\n<blockquote><p>Rules governing mental processes for 60-120 seconds also govern mental processes for 45-80 minutes.<\/p><\/blockquote>\n<p>Honestly, I&#8217;m just not sure that&#8217;s plausible. My doubts spring from two sources.<\/p>\n<h2>Doubts, and More Doubts<\/h2>\n<p>In the\u00a0<strong>first<\/strong> place, I doubt this advice because it <em>extrapolates so far beyond the initial research conditions<\/em>.<\/p>\n<p style=\"padding-left: 30px;\">If research tells me something about &#8212; say &#8212; college students, that conclusion might also apply to 1st graders. <em>But it might not<\/em>. 1st graders aren&#8217;t college students.<\/p>\n<p style=\"padding-left: 30px;\">If research tells me something about adolescents in Iceland, that conclusion might apply to teens in Brazil. <em>But it might not<\/em>. Icelandic culture differs from Brazilian culture.<\/p>\n<p style=\"padding-left: 30px;\">And, if research tells me about mental functions over one minute, that conclusion might apply to 20 minutes. (Or 45, or 80.) But IT MIGHT NOT. One minute isn&#8217;t twenty.<\/p>\n<p>Long-time readers know I always focus on &#8220;boundary conditions.&#8221; From my perspective, this advice goes WAY beyond the boundaries of the initial research.<\/p>\n<p>By the way: I&#8217;ve asked SEVERAL wise people if they know of primacy\/recency research that goes beyond a minute or two. So far, the answer is &#8220;no.&#8221;<\/p>\n<p style=\"padding-left: 30px;\">The\u00a0<strong>second<\/strong> reason I doubt this advice because of the <em>specific mental functions<\/em> involved.<\/p>\n<p>As far as I can tell, researchers explain the primacy\/recency effect by talking about <strong>short-term memory<\/strong> and <strong>working memory<\/strong>.<\/p>\n<p>Both of these mental faculties describe\u00a0<em>very short-term mental functions<\/em>. In my grad-school classes, our profs typically said that working memory holds information somewhere between 5 and 30 seconds.<\/p>\n<p>If, in fact, the primacy\/recency effect results from short-term and working memory functions, then those findings almost certainly won&#8217;t apply to mental processes that take 30+ minutes.<\/p>\n<p>Like, say, our classes.<\/p>\n<h2>Just Answer the Question<\/h2>\n<p>If this advice doesn&#8217;t hold, what can research tell us about the &#8220;most important five minutes in class&#8221;?<\/p>\n<p>I&#8217;ve got two answers.<\/p>\n<p><strong>Answer #1: <\/strong><\/p>\n<p>I&#8217;ve asked lots of people if they have a resaerch-informed answer to this question. So far, no one has a strong &#8220;yes.&#8221; But, If I hear of one, I&#8217;ll pass it along.<\/p>\n<p>And, btw, a friend has answered &#8220;we really have to research that question!&#8221; So, I&#8217;ll let you know if\/when his results come through.<\/p>\n<p><strong>Answer #2:<\/strong><\/p>\n<p>Long-time readers know my mantra: &#8220;don&#8217;t just <em>do this thing<\/em>; instead, <em>think this way<\/em>.&#8221;<\/p>\n<p>In this case, I don&#8217;t think we can plausibly identify any one time slot that consistently generates the most learning.<\/p>\n<p>Instead, we want to use core ideas from cognitive science to structure lesson plans effectively.<\/p>\n<p style=\"padding-left: 30px;\">Use retriveal practice.<\/p>\n<p style=\"padding-left: 30px;\">Beware working-memory overload.<\/p>\n<p style=\"padding-left: 30px;\">Foster attention.<\/p>\n<p style=\"padding-left: 30px;\">Activate prior knowledge.<\/p>\n<p>And so forth.<\/p>\n<p>If we follow this approach, <strong>every minute<\/strong> will build ultimately &#8212; and more-or-less equally &#8212; toward students&#8217; learning.<\/p>\n<hr \/>\n<p>Castel, A.
