It is not always politically correct to admit in education that you have a problem with certain aspects of what I call “educational theory.” By that term I mean those first principles which drive the methods and principles that education colleges provide to prospective teachers across the country. Of course if you take a quick look at my book list, you will find that I have indeed have questions about some of those first principles. E.D. Hirsch, Jr. and Daniel Willingham, who between them have four of the titles on my list, are not fans of many of the ideas that come out of education schools today. In a previous post I detailed how an education professor told me to burn Hirsch’s The Schools We Need and Why We Don’t Have Them. So, the feelings are obviously mutual. Knowing that this tension exists, both within the academic world of teacher education and within my own experience, makes it all the more remarkable to hear about the research review conducted by Harold Pashler (UC-San Diego), Mark McDaniel (Washington University of St. Louis), Doug Rorher (University of South Florida), and Robert Bjork (UCLA).
Originally published in the journal Psychological Science in the Public Interest in 2009, this review looks at studies concerning the effectiveness of teaching to various learning styles in the literature. Specifically, they were looking for evidence from formal studies that would indicate whether or not there was evidence as to whether or not teaching to various learning styles was actually effective. Their conclusions, frankly, are stunning.
“We conclude therefore, that at present, there is no adequate evidence base to justify incorporating learning-styles assessments into general education practice. Thus, limited education resources would better be devoted to adopting other educational practices that have a strong evidence base, of which there are an increasing number.”
Wow!
For those who are not education professionals, allow me to explain why this is so important. There are several very prominent theories of education as well as teaching methods that pre-suppose that different learning styles exist. One of the more prominent theories is Howard Gardner’s theory of multiple intelligences, which states that people are predisposed to learning under one of several intelligences including verbal, visual, musical, kinesthetic (bodily motion), among others. There is differentiated instruction, which is championed by Carol Ann Tomlinson (ironically from the same university as Hirsch and Willingham, the University of Virginia). Differentiation is a teaching method by which content is delivered to students in various forms in an attempt to reach students in their various learning styles. These ideas are often relied upon when developing individualized education plans (IEPs) for students with special needs. IEPs are required for students covered under the Individuals with Disabilities Education Act (IDEA), and failure to provide services under an IEP can potentially lead to a federal civil rights lawsuit. The review also notes that a sizable industry has arisen to sell schools tools with which teachers can determine what learning styles their students have and what methods they can use. This research takes a lot of these ideas, long accepted and promoted in education, to the proverbial woodshed for good old fashioned whipping.
When ideas have such a long history of acceptance, and have been championed by professionals who are this widely respected (and largely built their careers on them), it is natural to have some criticism come forth. Given that the research review is already two years old, such criticism has likely already happened behind the scenes. As long as the discussion simply stayed in the halls of academia the immediate effect would likely be minimal to a classroom teacher like me. However, on Monday Professor Rorher was interviewed about the review on National Public Radio’s All Things Considered. Now the results are not only in the public view, but also accessible to me a teacher on the front lines. I was able to download the full article from Professor Rorher’s website at the University of South Florida. (The full title is “Learning Styles: Concepts and Evidence”.)
My own personal interest in the topic other than the obvious professional implications has to do with the doubts I have had all along concerning the theories surrounding learning styles and differentiation. During my education courses I have several projects on these topics in several different classes. Even after my initial teacher training was over, I took more continuing education courses on these topics in order to become eligible for tenure. With that much training one would think I was an expert on the topic and be quite adept at implementing the methods in my classroom. It never happened, and mainly due to my own doubts, which initially concerned how practical this would be when I see 120 students per day in six groups of 20 for a total of 45 minutes per day for each group. (Oh yeah, and I teach three different laboratory science courses.) Those doubts have since spread to more philosophical issues regarding what this and other predominant ideas in education assume about the nature of students. It is one thing to focus on the diversity of student preferences about how they would like content to be delivered, and another to effectively teach to it. The authors do a very good job of making that distinction in the article. Unfortunately, the principle of multiple learning styles (and the vast majority of educational theory) assumes that diversity alone is the answer to how to effectively teach. When that is the assumption we lose what Ravi Zacharias refers to as the “unity from diversity”, from which we actually derive the term “university.” I went into education with the firm belief in truth of what the psalmist wrote when he said,
“I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well.” – Psalm 139:14
That making comes in many diverse facets, but there are certain aspects that are the same in each human. Research into brain function is suggesting that focusing on the similarities between students may be a better way to go for teachers. A lot of this research is being distilled into the concept of “brain based learning” which is gaining ascendency, not only in the larger world of education but also in my classroom and teaching. I have noticed that this idea also has blind spots, especially in its tendency to reduce the learning process to what C.S. Lewis referred to as “chemical phenomenon” in his masterpiece That Hideous Strength, but I believe it gives a more accurate picture of students as learners that I am able to use until such time that the picture becomes more in line with how God sees (and wants me to see) learners.
Will this research signal the death knell of learning styles? Not right away and maybe not ever. The authors are actually open to research on whether learning styles can be effectively matched to content such as verbal approaches for a writing class or a spatial approach to geometry, but no data has been made available to examine. I fully expect those who have staked their careers on learning styles to defend their positions rigorously. I saw this many times in the world of science and engineering. It is a natural reaction to being challenged, and when done with discipline (sometimes extremely difficult to do!) can be very constructive. In the meantime schools and their teachers will likely continue to differentiate instruction, sometimes on strict orders to do so. I just hope that hasn’t been a complete waste of valuable tax dollars and even more valuable time, because if it has then there will be more painful trips taken to the woodshed in the future.
