This document analyzes the impact of ICT training for teachers using both quantitative and qualitative measurements. Questionnaires measured changes in teachers' computer self-efficacy (CSE) and teaching self-efficacy (TSE) over time, finding that Group A's CSE increased slightly while TSE remained stable, with no correlation between the two. Interviews explored sources of self-efficacy like mastery experiences. Qualitatively, Group B teachers already used technology in various ways, while Group A incorporated more uses over time. Though teachers used ICT, they did not necessarily link this to feeling like better educators, explaining the lack of CSE-TSE correlation. The study shows how mixed methods can provide complementary insights into
