Effective teaching and learning strategy is one of the most important topics in the field of teachers' professional development. Teachers' education and pre-service teachers' training programmes provide necessary coursework, field experience, and student teaching internship experience to pre-service, potential, and second career teachers who are…

MyPedia is an integrated, multi-subject system of learning for early and late elementary schools. Developed initially for modern aspiring private schools in India, it aims to support measurable improvement in learners' thinking skills. Each lesson in MyPedia is built on the 5i model of instruction, which structures the learning process into five…

The study investigated the effect of problem-based learning (PBL) on students' achievement in chemistry. Learners' low achievement in Science in South Africa has been a concern to government, stakeholders, school principals and parents over the years as a result of poor teaching techniques, students' attitudes, lack of teaching and learning…

For most millennials, information has always been a couple of quick taps away. Sites have seemingly always existed to provide them with "the answer."
