I agree with poster above who recommended RA—the specific strategies recommended are great for helping students learn to engage in text-based problem-solving and close reading. Anything you can do to model how you, a professional in the field, actually engage in your discipline’s literacy practices is gold for students. Modeling the Think Aloud process as you tackle a journal article goes a long way in helping them understand and start to acquire the epistemology of your discipline. If you’re not able to take the RA course, the text is worth the $35.
I’m a CC literacy instructor (I largely teach stand-alone reading courses and also moonlight in our ENG department teaching first-year comp) and I work with students on reading journal articles throughout the semester. I have tried the one-shot approach, but it didn’t work well in my context—my students are usually first-semester or year, so it’s more about exposure to diverse forms of academic text—they don’t typically have the background knowledge necessary to critically evaluate the argument or study being presented, and a three-hour sustained reading period wouldn’t be effective for them.
I’ve moved to a model where we focus on a couple articles over the course of the semester and chunk up the analysis: today we’ll look at structure, next week we’ll identify the argument, later we’ll look at the audience and purpose of the text, and so on. It’s also a nice time to teach them about citation mining for new sources and why citations/references are so important to developing knowledge (and therefore why it’s such a huge deal when they don’t do that!). One of the end of semester assessments is an analysis of a new journal article. I don’t have any suggestions for the in-class activities beyond what you’re already doing with small grouping—that’s how I approach it as well.
Also, kudos for doing this! Literacy is almost always better taught in context, so I’m always thrilled to hear that there are colleagues “in the disciplines” who are willing to take some class time to work on disciplinary literacy strategies!
