Spaced Repetition & Interleaved Practice in Legal Research Instruction

Researchers refer to single-minded practice as "massed practice." This concentrated practice is thought to embed skills into memory. Unfortunately, while many students and teachers believe this to be the best way to learn, research doesn't support that idea. The problem with massed practice is that it is often accompanied by quick forgetting. Practice is important, but it is considerably more effective when it's spaced out--there's better retention and mastery.

It can be tough to convince our students of the benefits of spaced repetition. As Brown et al. point out in Make It Stick: The Science of Successful Learning:

 "[T]hese benefits come at a price: when practice is spaced, interleaved, and varied, it requires more effort. You feel the increased effort, but not the benefits the effort produces. Learning feels slower from this kind of practice, and you don't get the rapid improvements and affirmations you're accustomed to seeing from massed practice. Even in studies where the participants have shown superior results from spaced learning, they don't perceive the improvement; they believe they learned better on the material where practice was massed." [1]

Obviously, since this kind of learning requires more effort and doesn't lead to rapid improvement, students may push back against it. There are a couple ways we, as instructors, can help. The first is to explain the science to our students. Be upfront about its benefits to learning and why you are using this methodology--to ensure our law students fully absorb these critical research and analysis skills that they will be using over their lifetime in practice.

The second is to plan our syllabi carefully, spreading out skills across the semester. For example, rather than spending multiple class sessions focusing solely on statutes and then moving on to cases, blend these skills across the semester (and, where possible, across students' entire law school careers) so they are re-engaging with the skills they were introduced to in past weeks throughout the semester. Yes, this can challenge both the student and the teacher, as the grasp of each individual skill will come slower, but the good news is that interleaved practice has the same benefits as spaced repetition--long-term retention and mastery of the skills.

An added bonus is that interleaving and variation also help students "learn better how to assess context and discriminate between problems, selecting and applying the correct solution from a range of possibilities." [2] Given that employers and teachers of legal research report that students have difficulty applying their research skills to new contexts, it is clear that while interleaving and spaced repetition may challenge our students more, they would also better prepare our students for practice.

Why Experts Can Struggle to Teach Novices

This week in our Slack group on teaching , there was an interesting discussion about expertise and the amount of time needed to prep for instruction. I mentioned something that I recalled reading: that experts can be less effective in teaching novices because often the expert skips cognitive steps that the novice learner needs to understand.  I thought I'd dig into this a little more today on the blog. The fact is novices and experts learn very differently.  The major reason for this is that experts not only know a lot about their chosen discipline, but they understand how that discipline is organized. As such, what has a clear structure to the expert is a jumbled set of unorganized information to the novice.  The information presented to novices "are more or less random data points."[1]  In contrast, when the expert learns something new in her area of expertise, she just plugs it into the knowledge structure that already exists in her long-term memory. Because the new

Motivation in the Legal Research Classroom

Motivating students in the legal research classroom can be a challenge. As we know, there are many false narratives surrounding students' conceptions of legal research's importance, interest level, and ease, all of which can result in a decrease in students' motivation to engage in this subject matter. There are two types of motivation--intrinsic and extrinsic.  Extrinsic motivation occurs when students are motivated by an outside reward or punishment;[1] in instruction, this is often the grades students will get on research assignments or the participation points they might receive for actively engaging with in-class exercises.  Intrinsic motivation , on the other hand, occurs when students are interested in the topic for its own sake.[2] Due to legal research's false narratives, students entering our classrooms tend to be drive primarily by extrinsic motivation.  The problem is, as Julie Dirksen aptly notes in her excellent book Design for How People Learn , &qu

Helping With Student Focus & Motivation in the Remote Classroom, Part 3: Limiting New Technologies to Reduce Extrinsic Cognitive Load

A librarian colleague used to say to me, "Technology is great until it's not." This couldn't be more true in the classroom.  As many of us prepare for a fall entirely or partially online, there's a rush to familiarize ourselves with lots of new educational technology to teach our classes. There's this sense that if you're not using the best and newest ed tech in your class, you're doing something wrong. Fortunately, the science doesn't back this up.  Using too many different types of technology can be a contributing factor to cognitive overload in students . Cognitive load is a term cognitive psychologists use to describe the mental challenge that the limitations of working memory puts on a student's learning.[1] Basically, working memory is extremely limited in both time and duration. Humans can only hold on to between four and nine "chunks" of information at any given time,[2] and can only hold on to new information in their worki

Rethinking Formative Assessment

We've seen an increased significance placed on formative assessment in the legal academy. Standard 314 of the ABA Standards requires that law schools use both formative and summative assessment methods in their curriculum. Its rational for doing so is "to measure and improve student learning and provide meaningful feedback to students." The ABA defines formative assessment methods as "measurements at different points during a particular course or at different points over the span of a student's education that provide meaningful feedback to improve student learning." Those of us in the legal research instruction business are no strangers to formative assessment. We are leaders in this in the law school curriculum, with rarely a class going by in which students do not practice their skills. Lately, though, I've been wondering whether I'm going about formative assessment in the way that will best provide meaningful feedback to students. In the mandato

Reflection in the Legal Research Classroom

Reflection is a critical component of experiential learning.  We see in ABA Standard 303 that experiential courses must include multiple opportunities for self-evaluation.  Self-evaluation is critically important to legal research.  Students must reflect on and assess their research methodology each time they research to continue becoming more efficient legal researchers and to determine what research strategies work best in which situations. [1] Reflection relates to several ideas found in cognitive theory that have been shown to result in stronger learning and retention: Retrieval : recalling recently-learned information;  Elaboration : finding a nexis between what you know and what you are learning; and  Generation : putting concepts into your own words and/or contemplating what you might do differently next time. I've been contemplating how to better incorporate reflection into legal research classes. At the beginning of this semester, at the recommendation of a works
