When we reach a high level of expertise in our fields, it becomes very easy to forget that students, unlike disciplinary experts, have yet to build comprehensive conceptual structures into which they can add the new information encountered in our courses. Because their disciplinary knowledge organization models are still under construction, students might not be sure how discrete pieces of knowledge learned from lectures, videos, or readings fit together into a larger whole. When students are exposed to new information, it is very difficult for them to prioritize and organize what they are learning, or to make the kinds of meaningful connections required for lasting knowledge acquisition. As instructors, we can significantly boost student learning by providing (or inviting students to construct) knowledge organization systems that allow learners to sort, group, and structure new information. Here is how:
Meta-cues
The simplest way to indicate conceptual hierarchies and relationships, especially during a longer lecture, is to overtly communicate the lecture’s conceptual structure to the students. Simple meta-cues like, “We will now look at the three main factors determining X,” or “This is the most important concept for understanding Y,” or “Let’s recap the five sub-categories of Z” can help students sift through information, identify seminal points, and focus on what matters most. Asking students to point to key ideas and draw connections (through quick surveys, retrieval exercises, minute papers, or note-processing pauses) is another way to ensure learners begin constructing knowledge organization systems in our fields.
Skeletal notes
A quick glance at the notes our students take during a lecture, video viewing, or reading can offer insight into the state of their knowledge organization systems. Are our students able to identify main ideas? Make connections between concepts? Separate the seminal from the incidental? Discern categories and subcategories? Or do their notes reflect a conceptual schema that is fragmented, incomplete, or otherwise in the process of emergence?
One effective method of helping students organize new information is providing skeletal notes. Also known as skeleton notes, partial notes, or guided notes, skeletal notes are partially completed outlines that help students process new content (e.g. lecture, video, or help reading) and direct students’ focus to the details that require attention. While skeletal notes are typically text-based, some instructors use mixed media notes that combine text with graphs or other visuals (see example of hybrid skeletal notes created by Professor Susan Reynolds).
In addition to their effectiveness in improving student outcomes, skeletal notes offer an example of high-structure pedagogical practice: an equitable approach to teaching that aims at rectifying educational inequities by providing the scaffolding students need to succeed.
Visualizations
In addition to providing cues and structured notes, instructors can help students visualize the conceptual schema of a course, course module, or individual lesson with the help of visualizations like diagrams, flowcharts, or concept maps. Visualizations can be instructor-generated, student-generated, or skeletal (to be completed by students in the course of a lesson, module, or class). Beyond static one-time visualizations, iterative concept maps can help students track their growing understanding of a concept or subject throughout a term and make visible the process of constructing disciplinary schemas.
More specialized modes of visualization can help students organize information on spatial and temporal planes. In his 2019 book Intentional Tech: Principles to Guide the Use of Educational Technology in College Teaching, Derek Bruff shares several examples of advanced visualization assignments using geographical maps (aided by Google maps) and timelines (built with software applications like TikiToki) to analyze literary fiction or track the diachronic development of religious traditions.
In addition to providing valuable conceptual scaffolding for individual students, skeletal notes and visualizations lend themselves very well to collaborative learning. By comparing and collaborating on their notes and visualizations (from advanced digital modelling to hand-drawn sketches or sticky notes posted on the classroom whiteboard) students benefit from their classmates' diverse perspectives—and from the opportunity to articulate their own. Fueled by the power of peer instruction, the result is a more comprehensive understanding of individual course concepts and of their place within broader (academic and non-academic) knowledge systems.
