Instructional mechanisms potentially relevant to cognitive load management in Guzheng learning.
| Mechanism | Main instructional role | Potential cognitive implication | Typical Guzheng application | References |
|---|---|---|---|---|
| Worked examples and demonstration-guided practice | Provide an external model before independent execution | May reduce unnecessary problem generation and help stabilize early attention, especially for novice learners | Teacher- or video-based modeling of fingering, posture, and timing before learner imitation | Makransky and Petersen (2021); Nückles et al. (2020); Tammeleht et al. (2020); Janson et al. (2019); Singh et al. (2019); Singh et al. (2020) |
| Segmented practice | Divide a complex task into more manageable units | May reduce momentary processing burden by limiting the number of elements handled simultaneously | Practicing a phrase, hand function, or technical pattern separately before later reintegration | Nückles et al. (2020); Tammeleht et al. (2020); Nooijen et al. (2024); Li et al. (2023); Huang et al. (2021); Sala et al. (2019) |
| Scaffolding fading | Gradually withdraw instructional support as performance stabilizes | May support a shift from externally guided practice toward greater self-regulated control | Moving from full cueing to limited prompts and then to more independent rehearsal | Nückles et al. (2020); Tammeleht et al. (2020); Nooijen et al. (2024); Li et al. (2023) |
| Immediate feedback | Address unstable motor errors during early execution | May interrupt inefficient technique formation, although excessive use can increase momentary load or dependence | Real-time correction of finger angle, plucking force, or hand position | Brand et al. (2020); Fontaine et al. (2019); Yin et al. (2024); Divekar et al. (2021) |
| Delayed feedback | Create space for reflection and self-monitoring after task completion | May support a deeper review of performance patterns without interrupting performance flow | Reviewing recordings after a full phrase or practice cycle | Nückles et al. (2020); Tammeleht et al. (2020); Brand et al. (2020); Lanqin et al. (2021) |
| Adaptive feedback and support | Adjust guidance according to learner needs and task difficulty | May help keep challenge and support in a workable balance under some conditions | AI- or platform-based prompts that isolate recurring errors or adjust task difficulty | Azevedo et al. (2022); Fontaine et al. (2019); Yin et al. (2024); Lanqin et al. (2021); Divekar et al. (2021) |
This table is a summary of the main instructional mechanisms addressed in the review, such as worked examples, segmented practice, scaffolding fading, and feedback timing. The cognitive implications presented here have been backed up with evidence of different levels of directness. Some are based on direct discussions about Guzheng, others on more general studies of music and instrument learning, and others on related complex-skill literature that can elucidate mechanisms that may be transferable. All these entries must thus be seen as an organized form of synthesis of the existing evidence and not as a set of standard findings concerning Guzheng teaching.
