Chemistry: Structure and Dynamics, 5th Edition emphasises deep understanding rather than comprehensive coverage along with a focus on the development of inquiry and reasoning skills. While most mainstream General Chemistry texts offer a breadth of content coverage, the Spencer author team, in contrast, focuses on depth and student preparation for future studies. The fifth edition is revised in keeping with our commitment to the chemical education community and specifically the POGIL (Process Oriented Guided Inquiry Learning) Project. This text reflects two core principles, first that the concepts that are covered are fundamental building blocks for understanding chemistry and second, that the concepts should be perceived by the students as being directly applicable to their interests and careers. The authors further provide this "core" coverage using 1 of 3 models; data-driven, chemical theories and student understanding, which allows for a more concrete foundation on which students build conceptual understanding.
