A new model for understanding the growth of science teacher professional knowledge

The world around us is changing at high speed. New technological devices or processes are being continuously proposed by companies or organisations for improving our ways to interact with the physical or social environment. They all necessitate new competencies or new adaptations of already mastered competencies. The world is facing huge challenges. Reducing climate change will require new ways to use energy to be discovered, while preserving the planet’s resources and reducing carbon dioxide emissions. Overcoming these challenges will require all citizens to have a better understanding of science if they are to participate actively, responsively and responsibly in knowledge-based innovation and science-informed decision-making. To achieve these purposes, mathematics, science, and technology education have a crucial role to play (EC, 2015).
