Perhaps we might rely on various educational and scientific theories. Or, we might turn to data. Even\u00a0<em>big<\/em> data.<\/p>\n<p>Researchers in Sweden wondered if they could use the TIMSS test to answer this question.<\/p>\n<p>(&#8220;TIMSS&#8221; stands for &#8220;Trends in International Mathematics and Science Study,&#8221; given every four years. In 2015, 57 countries participated, and <a href=\"http:\/\/timss2015.org\/timss-2015\/about-timss-2015\/\" target=\"_blank\" rel=\"noopener\">580,000 students<\/a>. That&#8217;s A LOT of students, and a lot of data.)<\/p>\n<h2>3 Math Teaching Strategies<\/h2>\n<p>When students take these tests, they answer questions about their classroom experience.<\/p>\n<p>In particular, they answer questions about 3 math teaching strategies. They are asked how often they&#8230;<\/p>\n<p style=\"padding-left: 30px;\">Listen to the teacher give a lecture-style presentation.<\/p>\n<p style=\"padding-left: 30px;\">Relate what they are learning in mathematics to they daily lives.<\/p>\n<p style=\"padding-left: 30px;\">Memorize formulas and procedures.<\/p>\n<p>Researchers want to know: do any of these teaching practices correlate with higher or lower TIMSS scores? In other words, can all these data help us evaluate the effectiveness of specific teaching practices?<\/p>\n<h2>2 Math Teaching Theories<\/h2>\n<p>Helpfully, the researchers outline theories why each of these practices might be good or bad.<\/p>\n<p>As they summarize recent decades of math-teaching debate, they explain that &#8220;researchers with their roots in psychology and cognitive science&#8221; champion<\/p>\n<p style=\"padding-left: 30px;\">formal mathematical notions,<\/p>\n<p style=\"padding-left: 30px;\">explicit instruction where teachers show students how to solve math problems,<\/p>\n<p style=\"padding-left: 30px;\">practicing and memorizing rules and worked examples.<\/p>\n<p>On the other hand, &#8220;researchers with their roots in the reform movement&#8221; champion<\/p>\n<p style=\"padding-left: 30px;\">connecting math to students&#8217; daily lives,<\/p>\n<p style=\"padding-left: 30px;\">a problem-solving approach,<\/p>\n<p style=\"padding-left: 30px;\">understanding ideas and connections, rather than memorization.<\/p>\n<p>Doubtless you&#8217;ve heard many heated debates championing both positions.<\/p>\n<h2>Predictions and Outcomes<\/h2>\n<p>These theories lead to clear predictions about TIMSS questions.<\/p>\n<p>A cognitive science perspective predicts that &#8220;lecture-style presentations&#8221; and &#8220;memorizing formulas&#8221; should lead to higher TIMSS scores.<\/p>\n<p>A reform-movement perspective predicts that &#8220;relating math to daily life&#8221; should lead to higher scores.<\/p>\n<p>What did the data analysis show?<\/p>\n<p>In fact, the <strong>cognitive science predictions came true<\/strong>, and the reform predictions did not.<\/p>\n<p>In other words: students who listened to presentations of math information, and who memorized formulas did better on the test.<\/p>\n<p>Likewise, students who applied math learning to daily life learned less.<\/p>\n<h2>An Essential Caveat<\/h2>\n<p>As these researchers repeatedly caution, their data show CORRELATION not causation.<\/p>\n<p>It&#8217;s possible, for instance, that teachers whose students struggle with math resort to &#8220;daily life&#8221; strategies. Or that both variables are caused by a third.<\/p>\n<h2>Potential Explanations<\/h2>\n<p>&#8220;Connecting new math learning to real life situations&#8221; seems like such a plausible suggestion. Why doesn&#8217;t it help students learn?<\/p>\n<p>These researchers offer two suggestions.<\/p>\n<p><strong>First<\/strong>, every math teaching strategy takes time. If <a href=\"https:\/\/braindevs.net\/blog\/\/benefits-of-direct-instruction\/\" target=\"_blank\" rel=\"noopener\">direct instruction is highly effective<\/a>, then anything that subtracts time from it will be less effective. In other words: perhaps this strategy isn&#8217;t harmful; it&#8217;s just less effective than the others.<\/p>\n<p><strong>Second<\/strong>, perhaps thinking about real-life examples limits transfer. If I use a formula to calculate the area of a <em>table<\/em>, I might initially think of it as a <em>formula about tables<\/em>. This fixed notion might make it harder for me to transfer my new knowledge to &#8212; say &#8212; rugby fields or floor plans.<\/p>\n<p>At present, we can&#8217;t know for sure.<\/p>\n<p>A final point. Although this research suggests that direct instruction helps students learn math, we should remember that <em>bad direct instruction is still bad<\/em>.<\/p>\n<p>Lectures can be helpful, or they can be deadly tedious.<\/p>\n<p>Students can memorize pertinent and useful information. Or, they can memorize absurd loads of information.<\/p>\n<p>(A student recently told me she&#8217;d been required to memorize information about 60 chemical elements. Every science teacher I&#8217;ve spoken with since has told me that&#8217;s ridiculous.)<\/p>\n<p>And so: if this research persuades to you adopt a direct-instruction approach, don&#8217;t stop there. We need to pick the right pedagogical strategy. And, we need to execute it well.<\/p>\n<p>Cognitive science can help us do so..<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Analyzing TIMSS data, researchers draw tentative conclusions about math teaching: memorizing formulas &#038; hearing lectures vs. applying math to &#8220;real life.&#8221;<\/p>\n","protected":false},"author":18,"featured_media":3980,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[15,39,50,32],"class_list":["post-3975","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-lb-blog","tag-classroom-advice","tag-elementary-school","tag-middle-school","tag-stem"],"_links":{"self":[{"href":"https:\/\/www.learningandthebrain.com\/blog\/wp-json\/wp\/v2\/posts\/3975","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.learningandthebrain.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.learningandthebrain.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.learningandthebrain.com\/blog\/wp-json\/wp\/v2\/users\/18"}],"replies":[{"embeddable":true,"href":"https:\/\/www.learningandthebrain.com\/blog\/wp-json\/wp\/v2\/comments?post=3975"}],"version-history":[{"count":7,"href":"https:\/\/www.learningandthebrain.com\/blog\/wp-json\/wp\/v2\/posts\/3975\/revisions"}],"predecessor-version":[{"id":3983,"href":"https:\/\/www.learningandthebrain.com\/blog\/wp-json\/wp\/v2\/posts\/3975\/revisions\/3983"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.learningandthebrain.com\/blog\/wp-json\/wp\/v2\/media\/3980"}],"wp:attachment":[{"href":"https:\/\/www.learningandthebrain.com\/blog\/wp-json\/wp\/v2\/media?parent=3975"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learningandthebrain.com\/blog\/wp-json\/wp\/v2\/categories?post=3975"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learningandthebrain.com\/blog\/wp-json\/wp\/v2\/tags?post=3975"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
