In the twenty-first century, rapid technological change has transformed education, requiring teachers to integrate digital tools into dynamic, student-centered learning environments. This paper examines professional development (PD) as a vital pathway for preparing teachers to engage effectively with technology in ways that foster creativity, collaboration, and critical thinking. Research shows that effective PD extends beyond one-off workshops or technical training to embrace sustained, collaborative, and practice-based models that promote continuous growth. Frameworks such as Technological Pedagogical Content Knowledge (TPACK) and the Substitution–Augmentation–Modification–Redefinition (SAMR) model provide guidance for aligning technology with pedagogy and curriculum goals. Key dimensions of successful PD include enhancing teachers’ technological literacy, strengthening pedagogical strategies for digital classrooms, and cultivating adaptability and lifelong learning. Evidence indicates that well-designed PD improves teacher confidence and student learning outcomes while helping educators move beyond superficial uses of technology toward transformative integration. Ultimately, meaningful professional development is essential for equipping teachers with the capacity to prepare learners for participation in a knowledge-driven society, where digital competence and innovation are central to educational and economic success.
