Eighteen months of video-coded individual music lessons across three teacher-student dyads showed each pair converging on a distinct, self-reinforcing interaction pattern (a directive/entrenched pattern, an unsettled pattern, or a positive "flow" pattern), with a student's initially low autonomy need predicting a more directive trajectory and a sudden large increase in teacher autonomy support failing to stick when it was too far outside the dyad's established pattern.

Subclaims¶

q2 i1 "Out-of-synch" moments (mismatches between student autonomy expression and teacher autonomy support) significantly decreased over 18 months for all three dyads (p=.02, p=.002, p=.02), indicating growing mutual adaptation regardless of whether that adaptation was toward an optimal or suboptimal pattern. → Kupers et al. 2017

q2 i1 One teacher-student dyad with a low-autonomy-need student showed a significant decrease in scaffolding contingency over time (p=.02) alongside a significant increase in teacher directiveness (p=.001), consistent with a negative reinforcing loop in which teacher directiveness and student passivity escalated together into an entrenched teacher-led pattern (57% of lessons in that state, by cluster analysis). → Kupers et al. 2017

q2 i1 A dyad with a high-autonomy-need student showed an early resistance phase followed by a shift, sustained across the majority of later lessons (50% by cluster analysis), into a "flow" state combining high contingent scaffolding, high engagement, and high teacher autonomy support — reached through the teacher's persistent (not immediately reciprocated) autonomy-supportive framing during the student's initial resistance. → Kupers et al. 2017

q2 i1 A third dyad's teacher attempted a sudden, large increase in autonomy support (prompted by the student expressing a wish to quit) after a prior directive pattern; the student did not respond to the shift, and the dyad reverted within a few lessons to a directive, skill-focused pattern — illustrated as a case where a change too far outside the dyad's established interaction pattern failed to take hold. → Kupers et al. 2017

q2-q3 · intensive longitudinal microgenetic study (3 purposively-selected extreme-case dyads, 28 video-coded lessons each over 18 months) combining Monte Carlo significance testing of individual time-series trends with post-hoc hierarchical cluster analysis; high inter-rater reliability (Cohen's κ .78-.96); not a controlled or randomized design, N=3 dyads selected as extreme cases from a larger pool of 8 i1-i2 · statistically significant, precisely reported time-series trends for the quantitative claims; the attractor-state/cluster-analysis findings are qualitatively rich and theoretically well-motivated but post-hoc and based on 3 cases · associational · r1

Three violin/cello teacher-student dyads (students purposively selected as the most extreme cases for teacher-rated autonomy need from a larger pool of 8) were video-recorded for the first 10 minutes of four consecutive lessons at 7 time points across 18 months (28 lessons per dyad), and coded for teacher autonomy support, student autonomy expression, and scaffolding contingency. Monte Carlo tests on individual time series established significance of within-dyad trends; hierarchical cluster analysis on normalized, smoothed data identified qualitatively distinct recurring interaction states per dyad, interpreted through Complex Dynamic Systems theory as evidence that dyads settle into self-reinforcing "attractor" patterns, informing Persistent Autonomy Support During Resistance.

Discussion¶

This is an intensive microgenetic case study of three purposively-selected extreme cases, not a representative or randomized sample — the three trajectories are informative illustrations of a theoretically-motivated mechanism (self-reinforcing dynamics, attractor states) rather than a generalizable base rate of how one-on-one instruction typically unfolds. The cluster analysis is post-hoc, and the "sudden shift fails" finding rests on a single illustrative case within one dyad. The quantitative time-series trends (out-of-synch decline, contingency and autonomy-support slopes) are statistically tested and precisely reported, including honest null and marginal results (e.g., Robin's contingency slope at p=.06), which supports trusting the reported significant findings as not selectively reported.
