Accidents involving reactive chemicals can often be prevented, or their effects alleviated, if those handling them have a sound knowledge both of their hazardous properties and of appropriate handling methods. This book addresses this need. It opens with a definition of the key technical terms and evaluation methods for hazardous materials are outlined. Chapter 2 covers accidents involving self-reactive substances, accidents occurring during chemical reactions, and accidents involving hazardous products in the event of an earthquake. In the next three chapters, methods for evaluating fire an

Policy makers around the world recognise the importance of developing young people's 21st century skills like problem solving, creative thinking, self-regulation and collaboration. Many countries also include these skills as part of the intended learning outcomes of their education systems. To shift intention into practice, educational assessments need to better measure what matters. Innovative assessments are needed that combine conceptual, technological and methodological advances in educational measurement. This report explores new approaches to measuring complex skills through a practical and applied assessment design lens, bringing together perspectives from leading experts to consider what we can learn from the learning sciences to define more authentic assessment experiences and expand the range of skills we are able to measure in both disciplinary and cross-disciplinary contexts of practice. The report also examines how technology can expand our possibilities for innovation, including the creation of more interactive and immersive problems and the generation of meaningful sources of potential evidence about students' proficiency. Finally, the report explores how we can make sense of the rich data captured in interactive digital environments using new analytical approaches, and how we can ensure the valid interpretation and use of results from innovative assessments.

The first atoms-focused text and assessment package for the AP® course. Fully aligned to the latest College Board's curriculum framework, Chemistry: An Atoms-Focused Approach helps students understand chemistry at the micro, macro, and symbolic level. Author and chemistry education researcher, Stacey Lowery Bretz has incorporated her research on how students construct and interpret multiple representations into clear visualization pedagogy, which emphasizes the particulate nature of matter and helps students become expert problem solvers. This pedagogy extends beyond the book into the AP® teaching, learning, and assessment package.
