CLOSING THE HOLES ON SWISS CHEESE KNOWLEDGE

Over the years, I have argued often on this blog that one of the really weak spots in education was the failure of students to close the holes on what I call �Swiss Cheese Knowledge.�   Thus, on the first day of class last week, I drew a block on the board and put holes in it.  I then explained the drawing to my students. When you leave class every day, your knowledge looks like a block of Swiss cheese.   It appears entirely solid.  However, it is full of holes�things you missed, things you misunderstood, things you did not quite catch.  I know the knowledge feels solid, but it really is not.   If you do not take action, those holes just get bigger as time passes and your memory begins to fade.   Having taught for nearly 50 years, I know where the holes are likely to be.   I can and will write test questions to expose those holes.  In many ways, testing is just an attempt to measure the quantity and size of the holes ...

The One Question Calculus Final

Image
By  Lew Ludwig  (Editor-in-Chief),  Denison University As the semester begins and we prep for classes, the practice of backward course design is a powerful way to get the most of the learning experience for our students. With this in mind, I thought I would share one of my favorite exam questions for a first semester calculus course, which appears below. I call it �the one question calculus final.� Now of course this is tongue-in-cheek, as the one question has over 15 questions. Nonetheless, this one question tour de force covers the full range of a first semester calc course. To substantiate this bold claim, I found a comprehensive list of typical topics in such a course at Wolfram Mathworld Classroom . The chart below cross-references each alphabetically listed topic with its specific question. While some questions touch on a range of topics, the cross-referencing refers to the primary reference. Why I like this question: I really like this question because it requires...

Use the MAA Instructional Practices Guide to Maximize Student Engagement with Math

Image
By guest bloggers Martha Abell, Georgia Southern University , and Linda Braddy, Tarrant County College If you enjoy Teaching Tidbits , be sure to get an electronic copy of the Mathematical Association of America Instructional Practices Guide, which is chock full of great ideas to help you and your students. The guide is available as a free download on the MAA website . The MAA IP Guide is intended for all instructors of mathematics: New graduate teaching assistants  Experienced senior instructors  Contingent faculty member at a two-year institution  New faculty member at a doctoral-granting institution  Instructors who want to transform their own teaching  Mathematicians delivering professional development to colleagues The guide boldly responds to challenges articulated in the 2014 INGenIOuS report and the 2016 Common Vision report, which both call for transformation within the mathematical sciences community toward deeper, more meaningful learning experience...

�I�m Worried About My Grade.� How to Pre-empt the End of Semester Panic

Image
By Julie M. Phelps , Contributing Editor, Valencia College As the end of the semester nears, educators brace for the inevitable student questions about their final grades. If you are anything like me, this can be distracting from my goal of the class: to teach mathematics and make a difference in student lives. Sometimes I find myself dreading the last couple weeks because many students are stressed and solely focused on the final grade, not on learning ways to utilize mathematics in their major. This year I decided to try something new and pre-empt student questions about their grades by having them reflect on their class work and engagement. To do so, I showed a YouTube video called � I am worried about my grade � to my College Algebra students at the beginning of the semester (just before the first test). While very basic, the video goes over the many ways we educators evaluate student performance, and how we make time for students to approach us outside of class. After showing the...

The Role of Failure and Struggle in the Mathematics Classroom

Image
By Dana Ernst , Contributing Editor, Northern Arizona University The purpose of this post is to generate discussion and to get us thinking deeply about our teaching practices. This post introduces teaching concepts that researchers and educators developed to promote student success. In an attempt to understand who is successful and why, psychologist Angela Duckworth has spent years studying groups of people in a variety of challenging situations. Over and over again, one characteristic surfaced as a significant predictor of success: grit. According to Duckworth , grit is passion and perseverance for long-term goals. One of the big open questions in cognitive psychology is how to develop grit. Growth Mindset Research suggests that one of the key ingredients to fostering grit is adopting a growth mindset . Psychologist Carol Dweck defines growth mindset as the view that intelligence and abilities can be developed with effort. In contrast, a fixed mindset is the belief that one's ...

How Transparency Improves Learning

Image
By Darryl Yong , guest blogger,  Harvey Mudd College When we clearly communicate to students the rationale behind our instructional choices, they are more likely to do what we intend, be more motivated to learn, and be more successful. It is an idea that is so simple and obvious and yet often overlooked. Recent research suggests that being more transparent with our students can improve their learning. In one study , conducted at the University of Nevada, Las Vegas (UNLV), first-year students who took introductory-level courses from instructors trained to be more transparent were more likely to enroll the subsequent year (a 90 percent retention rate compared with the prevailing 74 percent rate for first-time, full-time, first-year students). Mary-Ann Winkelmes and her colleagues at UNLV have developed a useful framework for making our teaching more transparent. Be more transparent about the purpose of your course content and activities. What knowledge and skills will stude...

The Most Important Days of the Semester � Part Two

(If you would like for me to send you an email whenever I post a new blog entry, just drop me a note at Jhoyle@richmond.edu and I'll add you to my list.) On October 1, 2017, I posted the first of a two-part blog entry on the importance of the 2-4 days after the first test of the semester.  This initial essay included an email that I sent to my current students immediately after their first test.   My assumption has long been that students are most interested in how to do well in a course as they leave the first test.   The email encouraged them to consider two specific aspects of their post-test assessment.  First, if they felt they had not done well, I made three suggestions about what might have gone wrong.   It is hard to improve without some identification of the problem.  Students who do not do as well as they had hoped should come up with an honest ending to this sentence prompt, �I did not do well on the first test because . . .� ...
