Evaluating Webinar-Based Environmental Impact Assessment Learning among Civil Engineering Students: Evidence from an IDP Talk Series

Abstract

Environmental Impact Assessment (EIA) is an important component of civil engineering education because it exposes students to environmental compliance, impact prediction, mitigation planning, regulatory procedures, and EIA report preparation. This study evaluates the effectiveness of the IDP Talk Webinar Series 2026 on Environmental Impact Assessment in enhancing students’ awareness and technical understanding of EIA processes. A quantitative survey design was employed. Data were collected from 99 webinar participants using a structured questionnaire measuring three constructs: EIA awareness, technical understanding, and perceived webinar effectiveness. The data were analysed using SPSS through descriptive statistics, reliability analysis, exploratory factor analysis, Pearson correlation, and multiple regression analysis. The findings revealed high levels of EIA awareness, technical understanding, and perceived webinar effectiveness. The reliability results showed excellent internal consistency for all constructs, with Cronbach’s alpha values ranging from .938 to .956. The factor analysis supported a three-factor structure, while correlation analysis showed significant positive relationships among EIA awareness, technical understanding, and webinar effectiveness. Regression analysis further indicated that both EIA awareness and technical understanding significantly predicted perceived webinar effectiveness. The study contributes to civil engineering education by demonstrating that industry-oriented webinar activities can strengthen students’ environmental literacy, procedural understanding, and professional readiness. It also provides useful evidence for improving future IDP activities by integrating practical EIA case studies, report review tasks, and expert-led professional sharing sessions.
