Abstract

Learning communities (LCs) can provide authentic, social learning experiences but require an extensive amount of time and effort to orchestrate, often more than instructors can provide in typical university courses. Extracurricular, undergraduate, student-led learning communities (SLLCs) overcome this cost through volunteer peer-instructors. Unfortunately, LCs theory is based exclusively on teacher-led LCs. Here we ask what instructional processes emerge in SLLCs? We conducted a qualitative case study of SLLC student leaders’ attempts to teach a project management practice (StandUp) to student innovation teams. We found that instruction in SLLCs takes the form of a bi-directional diffusion process, in which peer-instructors influence students’ decisions about what practices to participate in, and students influence peer-instructors’ decisions about advocating for practices. Three major findings support the bi-directional diffusion model. First, students’ participation in StandUp hinged on whether they saw the practice as valuable with respect to their social, learning, and/or performance goals. Second, peer-instructors struggled to persuade and scaffold students to participate in StandUp. Third, students influenced peer-instructors to stop advocating for StandUp. The bi-directional diffusion model highlights the practical importance of persuading students to participate in the community’s practices. The model suggests that we might support peer-instruction by promoting peer-instructors’ content knowledge about practices, their persuasion skills, and their motivation to advocate for practices.

Appendices

Appendix 1: Excerpts from interview protocol for team members and team leads

  • Can you tell me a bit about your project and how it’s been going?

  • How’s it been going working with your team?

  • What about your studio lead -- have you been talking with them much?

  • How have you been communicating with your team and your studio lead?

  • Thinking back to the last time you communicated with your studio lead, can you walk me through that interaction in as much detail as you can remember?

  • When do you have meetings?

  • What did you do during your last meeting? Can you tell me what happened in as much detail as you can remember?

  • You mentioned [StandUp – use participant’s language to refer to StandUp] -- could you tell me more about that?

  • Why do you use/do [StandUp]?

  • Can you walk me through the last time you used/did [StandUp]?

  • What do the other people in your group think about [StandUp]?

  • And they said that? Or you think they feel that way because of how they act?

  • Last time someone acted that way, can you tell me what they said and did as best you can remember?

Appendix 2: Coding scheme

Code

Full name

Applies to evidence of…

DT-K

Knowledge of StandUp (costs/benefits, how to use, knowledge of studio leads’ credibility)

What teams knew of the benefits and costs of implementing StandUp, including social benefits and costs (why teams should use StandUp):

 knowledge of compatibility with needs, values, and pre-existing ideas (knowledge of how StandUp aligns with my needs, values, and prior knowledge about design and teamwork)

 knowledge of relative advantage (knowledge of how StandUp is better than what we already do)

 knowledge of observability (knowledge of how to observe the beneficial impacts of using StandUp)

 knowledge of non-complexity (knowledge of how StandUp is non-complex)

 knowledge of trialability (knowledge of how we can try out StandUp without significant overhead costs)

 knowledge of social benefits and costs of StandUp

ALSO, teams’ knowledge of how to implement StandUp, including the processes and principles underlying how StandUp produces value.

ALSO, what teams knew of studio leads’ credibility as a source of information about design.

NOT team leads’ knowledge of teams attitudes (that is DT-A)

DT-A

Attitude toward StandUp

Design teams’ (affective/emotional) attitude toward StandUp, including generalized or vaguely articulated judgments about StandUp

ALSO team leads’ knowledge of team members’ attitudes toward StandUp

DT-D

Decision to adopt Standup or to reverse adoption

Design teams’ (including team members’ and team leads’) decisions about adopting StandUp, including their reasoning process in deciding:

 Future tense: “I will do X”

 OR past tense “I decided to do X”

DT-I

Implementation of StandUp or practices replacing StandUp

Design teams’ implementation of StandUp, and what design teams communicated to studio leads about StandUp, including communication about design teams’ attitudes toward, and knowledge of, StandUp (does not include within-team communication):

 Past tense: “we did X,” “we said something to the studio lead”

 OR general present tense: “we do X”

SL-K

Knowledge of StandUp advocacy and utility

What studio leads knew of the benefits and costs of advocating StandUp, the benefits and costs to teams using StandUp, why teams think they should use StandUp, whether teams like/dislike StandUp, how teams should implement StandUp, and the processes through which StandUp produces value

NOT how teams do use StandUp (unless the data segment also contains knowledge about 1+ of the 6 items listed above)

SL-A

Attitude about StandUp advocacy and utility

Studio leads’ (affective/emotional) attitude about StandUp and whether their advocacy of StandUp is going well, including generalized or vaguely articulated judgments

SL-D

Decision to advocate Standup or to cease advocacy

Studio leads’ decisions about advocating for StandUp, including evidence about their reasoning process in deciding

SL-AA

Advocacy actions

(includes communication about StandUp)

Actions studio leads took to advocate for StandUp:

 Communication

 Inexplicit communication/other advocacy (e.g. modeling or leading team in StandUp)
