Dividing your course content into manageable chunks helps students learn more effectively (Ambrose et al., 2013; Felder & Brent, 2016). It can also help you be more nimble if you need to make sudden changes to your course design. On this page, we will provide some guidance on how you can chunk content so students can effectively process your course concepts and learn more.
STRATEGIES & EXAMPLES
Chunk, Chunk It Up
First chunk out foundational concepts, then chunk out more complex concepts. For example, in Geology students must be able to characterize different types of magmas before learning to identify volcanic eruptions, because the magma characteristics dictate the type of eruption. If students learn about magmas first and fully, they will be much more successful at using that knowledge to identify eruptions. In general, you can encourage students to work on their comprehension of foundational concepts though activities such as focused reading notes or a background knowledge probe. Check out the downloadable materials from the previous links for templates and sample language for these activities.
Create a cycle of learning that introduces chunks of knowledge and gives students opportunities to engage actively with the chunks. You might create a cycle that requires students to encounter new ideas (lecture, video, or readings), and then practice engaging with those ideas (through low-stakes assignments, group interaction, or online discussions) in a “Learn, Explore, Do” format. For example, in a statistics course to “Learn” about linear regression, students encounter the topic using things such as guided notes and videos (Stachowiak, 2020). For the “Explore” phase, they visit a specific website, find a linear graph, make a dataset to match it, post their graphs in an online discussion board, and other students apply statistical concepts to the examples. For the “Do” phase, students complete problem sets on their own.
Give Students Time to Think and Process
For complex topics, encourage students to explore a problem before they receive instruction. Before you introduce a new topic, ask students to guess at what the topic might include. Ask them to review the headings throughout a chapter without reading the text. What is this chapter about? How might it relate to what they already know? This helps them apply their prior knowledge and structures of understanding, which can reduce cognitive load and allow them to process new information more efficiently (Lizarov, 2019).
Slow down and space out more complex material. Spend less time explaining easier concepts (or provide resources for learning outside of class such as videos, handouts, or brief texts), and have students spend more time working actively on harder concepts (Felder & Brent, 2016). Instead of using one slide to explain something complicated, show a process over several slides, images, or, better yet, activities. For example, the slide on the right of mitosis from Wikimedia Commons is full of important information but is overwhelming to process. Instead, divide this into multiple slides that allow you to point out key changes from one phase to the next.
Check Yourself
Actively assess whether your chunks are the right size. If it takes students more than a few minutes to complete a new formula, consider breaking the formula into smaller parts (Felder & Brent, 2016). Also, be sure to use regular formative assessment strategies such as the Critical Incident Questionnaire or the “muddiest point activity” (“What was the muddiest point in this week’s course?”) to see if students are keeping pace with your delivery of content.
Keep your videos short. Some sources say lecture videos for classes should be no longer than 6 minutes, some say no longer than 15 minutes (Burch; Lovell & Ostendorf, 2020). The precise length should depend on the complexity of the topic and what you want students to be able to do with the information. But if you’re looking for a broad recommendation, keep them around 10 minutes long.
