Continuous Professional Development through Online Training: Enhancing Teachers’ Professional Competencies in the Digital Era

Abstract

The rapid digital transformation of education has intensified the need for continuous professional development (CPD) that equips teachers with relevant digital, pedagogical, and content competencies. This study examines the effectiveness of online training as a modality for enhancing teachers’ professional competencies in the digital era. Drawing on a quasi-experimental pre-test/post-test design involving 180 in-service teachers who participated in a structured 10-week online CPD programme focused on digital pedagogy, technological pedagogical content knowledge (TPACK), and classroom integration of digital tools, the research measured changes in digital competence, pedagogical practices, self-efficacy, and instructional application. Results indicated statistically significant gains in overall professional competencies (medium-to-large effect sizes), with particularly strong improvements in digital literacy, resource creation, and technology-enhanced instructional strategies. Teachers also reported higher self-efficacy and greater intention to apply newly acquired skills. Findings align with recent meta-analyses showing that well-designed online professional development (OPD) produces medium effects on teacher-level outcomes and smaller but positive effects on classroom practice. The study concludes that online training, when interactive, collaborative, content-focused, and sustained, is an effective, scalable strategy for teacher CPD in the digital era. Implications for programme design, policy, and future research are discussed
