The document discusses problem based learning (PBL) and e-teacher education. PBL is defined as a student-centered instructional strategy where students collaboratively solve problems and reflect on experiences. Some advantages of PBL include improving active learning, developing life skills, and fostering critical thinking. E-teacher education involves using information and communication technology (ICT) to enhance teaching and harness the potential of digital technology. It aims to develop positive attitudes towards e-learning in pre-service teachers and support new pedagogical methods through collaboration and locating online learning resources.
