I would like to stay away from one shots if possible.
These seem like very difficult concepts to address and to teach to students from different disciplinary fields. IE History threshold concepts are very different from Biology, etc. The concept of Threshold concepts themselves are not widely accepted. Do we know enough about threshold concepts to "get the students over them"?
Students need to be in the right place developmentally and in their coursework, so there's a lot that needs to be in place for them to get over the threshold. It's very difficult for us to impose that on them, and in a sense that's not our job, but rather the job of the faculty member for the course.
Our role would be to get them to the place where they're potentially ready for the threshold concept and then faculty have to bring them over that threshold. Challenge is how to plan for/collaborate to achieve this.
Threshold Concepts vs Frames:
We need to decide where our focus is. Frames are more information literacy focused, threshold concepts are more discipline specific.
Standards vs Frameworks:
Because we didn't map our instruction program to the standards, we're starting from scratch in a way with the frameworks; this has benefits in that we're not tied to an existing way of mapping things/faculty don't have a set understanding of these concepts, but we're also in some ways skipping a step.
Getting students to realize, for instance, that searching is an iterative process and that it IS a process, is difficult. Students get married to the first thing they find, and to the first searches they do, and even when it doesn't work out they tend to struggle with those terms and ideas rather than adapting/modifying their ideas. How best to express and model the practice of iterative research is still a challenge.
Many of these types of programs and activities require more advance planning than a "standard" database instruction lecture; our culture has been very open to last-minute class bookings. Once challenge may be balancing the need for lead time in order to successfully implement the frames with faculty's reliance on the ability to make last minute reservations. Do we want to have that conversation?
