Kathy Schofield explains how the Primary Science Teaching Trust (PSTT) came into being and how it continues to enhance science for primary teachers and children. The Primary Science Teaching Trust provides financial assistance to help improve the learning and teaching of science in the U.K. The Trust was established in April 1997 as an independent charity operating with a substantial trust fund donated by AstraZeneca PLC. Its name was changed in 2013 to the Primary Science Teaching Trust (PSTT). It is now one of the major voices in the area of primary science teaching, and is developing an international reputation in order to continue with its original aim. In 2010, the Trust took on a new direction and strategy by establishing the Primary Science Teacher College, which drew together excellent teachers who can develop new projects, undertake professional development, and disseminate best practice from their own teaching. Some fellows are involved in larger projects with other institutions or partners that are also funded by the Trust. Currently, PSTT College is working to promote the teaching of the principles and big ideas of science education, which involves encouraging development in understanding of the nature, processes, and methods of science through different types of science enquiries, so children will become more able to answer scientific questions about the world around them.
