How to Create a Perfectly Difficult CSD Course Implementing "desirable difficulties" in an online course to increase acquisition of foundational knowledge Ashley M. Frazier and Celia R. Hooper University of North Carolina Greensboro
presentation objectives Upon completion of this session, learners should be able to 1. Identify four strategies shown to be effective in long-term learning of new information 2. Compare teaching methods which capitalize on these research-based strategies to other common strategies which might be less effective 3. Apply strategy knowledge to existing classroom teaching methods 4. Integrate "desirable difficulties" into class activity planning
agenda • Talk about 4 principles • Tell you about my class • Show you how course plan changed in response to the 4 principles • Talk about whether it worked • Discuss how desirable difficulties might work in other classrooms
where I’m coming from traditional techie hard ass bleeding heart
desirable difficulties (Bjork, 2011) • Vary the conditions of learning • Interleave instruction • Space study sessions • Use tests as study events
The basic problem learners confront is that we can easily be misled as to whether we are learning effectively and have or have not achieved a level of learning and comprehension that will support our subsequent access to information or skills we are trying to learn. We can be misled by our subjective impressions. Rereading a chapter a second time, for example, can provide a sense of familiarity or perceptual fluency that we interpret as understanding or comprehension, but may actually be a product of low-level perceptual priming. Similarly, information coming readily to mind can be interpreted as evidence of learning, but could instead be a product of cues that are present in the study situation, but that are unlikely to be present at a later time. We can also be misled by our current performance. Conditions of learning that make performance improve rapidly often fail to support long-term retention and transfer, whereas conditions that create challenges and slow the rate of apparent learning often optimize long-term retention and transfer. Bjork & Bjork- Making Things Hard on Yourself, But in a Good Way: Creating Desirable Difficulties to Enhance Learning
the upshot Learning may happen over time with no apparent change in performance Performance improvement can occur with no significant learning People are not good at predicting or recognizing learning when it is happening
varied learning conditions • the classic advice to “find a quiet place and always study there” is not the best way to learn • learning becomes contextualized to that condition • varying conditions of practice enhances learning • variation during learning supports better retrieval in novel test conditions
interleave instruction • blocked practice appears optimal for learning, but interleaved practice results in superior long-term retention and transfer of skills • may force learners to “reload” memories • interleaving even enhances inductive learning • forgetting (losing retrieval strength) creates the opportunity for increasing the storage strength of to-be-learned information or skills
space study • massing practice supports short-term performance • spacing practice supports long-term retention • the most intuitive of the 4 principles
testing as teaching • tests do much more than measure learning; they also enhance learning • the deeper, more difficult, and more complex retrieval is, the more powerful that retrieval will be • delayed tests constitute better practice for later recall because they exercise more of the processes needed to succeed on a later test, BUT • for an item to profit from being tested, the learner must be able to successfully retrieve that item from memory • Expanding schedule of tests benefit from the positive effects of delayed tests while not being harmed by recall failures
Desirable difficulties are desirable because they trigger encoding and retrieval processes that support learning, comprehension, and remembering
csd 250 • Intro/survey course • Online class • Mostly year 1 & 2 • About 50 students • Cover speech, language, hearing at introductory level • Changed class to incorporate 4 principles between Fall 2010 and Fall 2011
my assumptions • purpose of “intro course” is learning models, terminology, develop knowledge framework • share passion for the discipline to get students interested • help students become better learners & successful managers of their higher education experience
vary the conditions of learning rather than keeping them constant and predictable
varied learning conditions Fall 2010 Fall 2011 Weekly points Choice based assignments Big Project Choice of topic Choice of product Guided expectations • Discussion board posts • Post news items • Answer weekly question about reading/material • Informational blog • Final project; create blog on topic of choice
varied learning conditions Fall 2012 – How I’m doing it now Weekly points Choice based assignments Collaborative creation of materials: Quizlet, Wiki, Google docs Big Project Choice of topic Choice of product Guided expectations Peer Assessment incentivize variety
Weekly Points Students chose assignments from a menu to earn points each week I tried to offer at least 1 elaborative, 1 creative/experiential, 1 synthesis, and 1 analysis option each week, and students typically chose 2-3 to do Example: 5 points – Information to Share from Textbook Ch. 3Create a single page graphic organizer of key concepts/information from Chapter 3 – think of it as a “cheat sheet” for someone who didn’t read this week but needs to pass the quiz5 points - Create your own picture codeMake a one-page picture code that you could use to get through your school day if you weren't able to talk or write. Use it for one full day, and write 1-2 pages about this experience.10 points - Act It OutMake a YouTube video demonstrating each of the "Gestures associated with the Body" on p. 7 in your textbook, along with your verbal explanation of what you think at least ten of them might mean. Post your link.
Interleave instruction on separate topics, rather than grouping instruction by topic. That’s called blocking. It’s bad.
This didn’t change – instruction was interleaved for both groups Fortunately it is easy to construct coursework this way in CSD…
Space study sessions on a given topic, rather than massing study sessions That’s called cramming. It’s bad
spaced study Fall 2010 Fall 2011 Comprehensive quizzes Distribute study guide 2-3 weeks before exams Guided study session One midterm exam One final exam • One midterm exam • One final exam
spaced study Fall 2012 – How I’m doing it now Comprehensive quizzes Distribute study guide 2-3 weeks before exams Collaborative creation of study wiki with feedback Guided study session One midterm exam One final exam incentivize early
You can’t make your students study You can’t prevent your students cramming But you can make conditions optimal
Use tests • as study events, • rather than presentations. • retrieval practice works.
testing as teaching Fall 2010 Fall 2011 One quiz each week Every 3-4 weeks, comprehensive quiz Quizlet sets One midterm exam One final exam • One midterm exam • One final exam Quizzes were untimed and could be repeated, worth some points but not a lot. Quiz questions were low in identification, high on evaluation and analysis; quizlet sets focused on identification
testing as teaching Fall 2012 – How I’m doing it now • Set of chapter quizzes each week – MC, T/F, Short Answer • Every 3-4 weeks, comprehensive quiz • Quizlet sets for each topic • One midterm exam • One final exam
did it work? Difference: Incorporated 4 principles into curriculum Difference: Changed to Justice text, kept the same midterm & final
choosing a text things I considered • options for “extra” stuff – online quizzes, questions, cd with case studies, outlines, test bank • interleaving-friendly organization of topics/text • survey level with lots of links to more information Communication Sciences and Disorders: A Contemporary Perspective (2nd edition). 2009. Justice, L. M.. Boston: Allyn & Bacon
future • hybrid version of class – half online, half live Spring 2013 (reverse classroom) • managing cognitive load • compressed version of class – summer session 2013 • prepping course for other instructors
