Assessing Virtual Teaching Effectiveness: Development and Validation of the Teacher Evaluation (Tuvalu) Scales

The shift to virtual learning has necessitated effective assessment tools to evaluate students' experiences and satisfaction.This study aims to develop and validate the Teacher Evaluation (TEVAL) Scales to measure key dimensions influencing student satisfaction in virtual education.The study examines the impact of academic facilitation (AF), course structure (CS), interaction and engagement (IE), instructor support (IS), learning environment (LE), and student engagement (SE) on overall satisfaction.A sample of 532 students participated in the survey.The study employed Cornbrash's alpha, composite reliability, and average variance extracted (AVE) to assess reliability and validity.Results indicate high internal consistency across constructs (Cornbrash's alpha: 0.807-0.937).Convergent validity was confirmed with AVE values ranging from 0.581 to 0.800, while discriminant validity was assessed using the Fornell-Larcker criterion.The structural model fit indices showed SRMR = 0.106 and NFI = 0.740, indicating moderate model fit.Findings reveal that academic facilitation, instructor support, and student engagement significantly predict student satisfaction, while course structure and interaction and engagement show moderate effects.The study contributes to online learning research by offering a validated tool for assessing students' experiences and satisfaction.Future research should explore the longitudinal impact of these dimensions on academic performance.
