    Has anyone run across or have experience with David Kolb’s Experiential Learning Theroy and the Learning Style Inventory? I’ve recently run across a LinkedIn post where someone is advertising a class on how to implement it. I did a quick search on Kolb and he’s written quite a few books and articles. Most of his work was done in the early 80s, but I’m also seeing current research being done using both the Experiential Learning Cycles and the Learning Style Inventory. I found an article where he replies to Freedman and Stumpf who apparently criticized his Learning Styles Inventory. I am not able to share it here. Full disclosure, I haven’t read all of it, nor have I been able to dig too deeply into it, which is why I’m bringing the question here. Thanks.

    I noticed this eminent Ph.D. and Assistant Dean for Education Innovation providing insight on how to apply Dale’s Cone in learning: http://www.queensu.ca/teachingandlearning/modules/active/documents/Dales_Cone_of_Experience_summary.pdf

    What suddenly struck me was how at odds this “research” is with that of learning styles. If learning styles are a thing, then shouldn’t the percentages vary at each level of the cone depending on the individual’s learning style?

    I’m wondering why I’ve never seen any debate about this inherent contradiction from proponents.

    Reading an article in Inside Higher Ed in which our campus was featured for its initiatives to improve accessibility for our online content, I saw this little gem:

    …”accessibility efforts …can even serve students who don’t have learning disabilities but learn better from reading text than hearing it out loud…”.

    I see this all the time. Two problems with it. One, it so obviously assumes that learning styles are legitimate AND that the reader knows that and agrees with it. The term “learning styles” isn’t even used and doesn’t have to be. What’s not said is just as important as what is.

    And two, used in the context of accessibility, this kind of statement means precious resources of time and effort are being taken from REALLY making content accessible to PRETENDING to by addressing learning styles.

    This is why addressing myths about why people learn is so important. Real people with real learning problems don’t get helped when we mess around with junk science.

    Daniel Engbar, writing in Slate Magazine, argued earlier this year that the worries about Debunker were overstated. Here is his article: https://slate.com/health-and-science/2018/01/weve-been-told-were-living-in-a-post-truth-age-dont-believe-it.html

    Today Engbar (on Twitter) pointed us to another article which found evidence that another worry about debunking—that too many persuasion attempts might backfire—has been found to be false. It looks like more debunking efforts are better than fewer debunking efforts! Here’s the pre-publication research article: http://www.emc-lab.org/uploads/1/1/3/6/113627673/ecker.2018ip.jarmac.pdf

    I’m sure there will be more studies to come. We live in a time where fake news, misinformation, deception is rampant. Researchers will want to take a look to see what can be done.

    I am moderating a webinar teaching litigation support people how to write reports. The lovely slide of Edgar Dale’s cone defiled by percentages appeared with a “University of Texas” at the top as if this was a theory endorsed by them. That led me to a series of searches that ultimately landed me on this website.

    This piece from Campus Technology features people from my college who are part of the accessibility initiative at our university. It’s shot through with references to Learning Styles as a justification and argument in favor Universal Design for learning. One of the ways you make your learning “universal” is to attend to different learning styles. It’s maddening.
