This study examines the impact of targeted professional development on teachers' AI knowledge and confidence. 60 secondary school teachers participated in training on AI principles, applications, and classroom integration, using hands-on and collaborative approaches. The study uses a counterfactual design with pre-post measurements and a control and experimental group. The research measured changes in knowledge of AI concepts and affective responses to AI tools. Results show statistically significant improvements in the intervention group across multiple dimensions: general AI knowledge, familiarity with AI technologies and techniques, ability to distinguish AI from non-AI tools, and perceived ease of use. Teachers also reported increased engagement and reduced anxiety about AI integration, despite greater awareness of implementation complexity. Findings demonstrate that structured professional development combining conceptual understanding with practical application effectively builds foundational AI literacy. The results underscore the need for continuous professional development to address the rapid evolution of AI technologies.
