# Peer collaborative learning and academic engagement in university libraries: a moderated mediation model and latent profile analysis

## TL;DR

This study explores how peer collaborative learning in university libraries affects academic engagement, revealing that not all collaboration is beneficial and identifying distinct student groups.

## Contribution

The core contribution is identifying a 'pseudo-collaboration' trap through the discovery of the largest student group, 'Inefficient Socializers.'

## Key findings

- Latent Profile Analysis identified four student profiles, with 'Inefficient Socializers' showing high emotional support but low academic engagement.
- Basic psychological needs partially mediated the relationship between collaboration quality and academic engagement, accounting for 52.3% of the total effect.
- Academic discipline did not significantly moderate the effects observed in the study.

## Abstract

As university libraries transform into “Learning Commons,” peer collaborative learning has become increasingly common. However, the complexity of its effectiveness and its underlying mechanisms remain underexplored. This study systematically investigates the relationship between peer collaborative learning and academic engagement. Integrating both person-centered and variable-centered approaches, the study employs Latent Profile Analysis (LPA) to identify heterogeneous groups of students based on their collaboration patterns and engagement levels, challenging the conventional wisdom that “collaboration is always beneficial.” Concurrently, based on Self-Determination Theory (SDT), a mediation model is constructed to test the bridging role of basic psychological needs (competence and relatedness).

Using a questionnaire survey, data were collected from 820 university students to measure their quality of peer collaborative learning, basic psychological need satisfaction, and academic engagement. The SPSS PROCESS macro was used for mediation analysis, and Mplus was used for Latent Profile Analysis.

(1) LPA identified four heterogeneous profiles: “High-Achieving All-Rounders” (26.1%), “Balanced Developers” (25.5%), “Inefficient Socializers” (27.6%), and “Indifferent and Unengaged” (20.9%). Notably, the largest group, “Inefficient Socializers,” exhibited a distinct pattern of “high emotional support, low academic engagement.” (2) Basic psychological needs played a significant partial mediating role in the relationship between the quality of peer collaborative learning and academic engagement, with the mediating effect accounting for 52.3% of the total effect. (3) The moderating effect of academic discipline was not significant.

The study confirms that while high-quality peer collaboration can promote academic engagement by satisfying students' psychological needs, not all forms of collaboration are beneficial. The discovery of the “Inefficient Socializers”—the largest profile—is the core contribution of this research. It exposes the existence of a “pseudo-collaboration” trap, where social interaction detached from task-oriented goals may actually inhibit academic engagement. This finding offers crucial practical implications for the design of university learning spaces (shifting from “promoting co-presence” to “fostering effective interaction”) and for academic advising (enabling the precise identification and intervention for different student types).
