I started posting about student highlighting, note-taking, and annotation as part of my observation that reading with a digital device offers some lifetime advantages over reading paper resources. The issue of comprehension vs. paper is only the initial stage of reading and the opportunities for layering personal comments on primary sources, the storage and organization of these comments, and the retrieval of these comments offers advantages for studying and written projects based on ideas from multiple sources.
Once you begin exploring digital annotations and note-taking you can move into many different subtopics. For educators, any claims related to digital annotation and related activities (note-taking, highlighting) would typically involve short-term student uses of these skills (e.g., preparing for an exam, generating a multi-source written product).
There are many investigations and analyses related to these ends. If I were to recommend a single source relevant to this topic it would be one that is a couple of decades old. It is also a study conducted with college students. Simpson and Nist made several key points in their introduction that I believe continue to be of great importance. Even though and perhaps because they worked with college learners, I think their most important observation was that treatments that involve a skill such as highlighting or annotation require the assurance that learners applying these study strategies do so effectively. They raise the same argument I have made multiple times. Have learners ever received guidance in how they should go about learning strategies such as highlighting and annotation? If those investigating study techniques in college learners are concerned with what is often called treatment fidelity, a similar concern should be raised when conducting annotation, highlighting and pretty much any study strategy with younger learners.
The Simpson and Nist study developed over a three-week period of time using the type of content college students would encounter in their classes (I.e., extended period of time and authentic content). Students were exposed to sample annotated materials, provided examples of specific types of annotations (e.g., summaries, questions of understanding, potential examples), and offered samples of their attempts at annotation for review by peers and the instructor. The comparison of multiple choice questions responses covering each target source involved the treatment group and a group asked to study and generate possible exam questions. The annotation group demonstrated a significant advantage on the MC exams.
This study made use of paper source material, but offers a realistic example of what it takes to apply the treatment strategies in a way that generates an advantage. It cannot be assumed that common study techniques such as highlighting or annotation are applied in a cognitively generative way even though some within a peer group use such strategies. It is very possible students have never been involved in a conversation focused on the use of such strategies or practiced them under supervision, Students read and write in most classes, but responsibility for developing proficiency in such skills in secondary and lower-level college classes may be one of those things assumed to be someone else’s job.
