This document discusses barriers to integrating information and communication technologies (ICT) into teaching and learning environments. It identifies several common barriers at the teacher and infrastructure levels. At the teacher level, barriers include lack of teacher confidence, competency, and motivation to change their practices. At the infrastructure level, common barriers are lack of adequate ICT resources, effective training, and infrastructure support. To improve ICT integration, the document argues that education systems must address these barriers by enhancing teacher skills and confidence, providing sufficient resources and training, and strengthening infrastructure support.
