Development and Validation of an Academic Engagement Scale for Undergraduate Students in Distance Learning
Main Article Content
Abstract
Distance education at open universities faces significant challenges, including high attrition rates driven by social isolation and the demands of self-directed learning. A context-specific instrument is essential for understanding the mechanisms that support student persistence. This study aimed to develop and validate an academic engagement scale, with development referring to the refinement of an existing framework. Drawing on constructivist and motivational theories, academic engagement was conceptualized as a second-order construct comprising cognitive, emotional, and behavioral dimensions. Data were collected from 440 students at Sukhothai Thammathirat Open University using cluster sampling based on academic disciplines (Social Sciences, Health Sciences, and Science and Technology). Confirmatory Factor Analysis (CFA) was conducted to examine the hierarchical structure, while Cronbach’s alpha, Average Variance Extracted (AVE), and the Heterotrait–Monotrait (HTMT) ratio were used to assess reliability and construct validity.
The model fit indices indicated an acceptable fit to the data (/df = 3.22, RMSEA = .07, CFI = .92, NFI = .91, and SRMR = .04). All dimensions demonstrated satisfactory reliability and validity, with HTMT values below .85, supporting the distinctiveness of the constructs. Cognitive engagement showed strong associations within the model, highlighting the role of self-regulated learning in distance education. The findings provide empirical support for a multidimensional structure of academic engagement and contribute a context-specific measurement tool that can be applied to support student engagement and retention in an open university distance learning context.
