Introduction to Chemistry 2nd Edition
As instructors of Introductory Chemistry, our lectures are signifi cantly different from traditional lecture presentations in many ways. Beginning with the fi rst week of classes and continuing through the rest of the semester, we follow a sequence of topics that allows us to explain macroscopic phenomena from a molecular perspective. This approach places emphasis on conceptual understanding over algorithmic problem solving. To help students develop conceptual understanding, we use numerous still images, animations, video clips, and live demonstrations. Roughly a third of each class period is devoted to explaining chemical phenomena from a conceptual perspective. During the remaining time, students work in groups to discuss and answer conceptual and numerical questions.
Our desire to create a conceptually based text stems from our own classroom experience, as well as from educational research about how students learn. This book is grounded in educational research fi ndings that address topic sequence, context, conceptual emphasis, and concept-embedded numerical problem solving. Throughout the text, we have made an effort to relate the content to studentsâ€™ daily lives and show them how chemistry allows us to understand the phenomenaâ€”both simple and complexâ€”that we encounter on a regular basis. Studentsâ€™ initial exposure to chemical concepts should be in the realm of their personal experience, to give context to the abstract concepts we want them to understand later. This text presents macroscopic chemical phenomena early and uses familiar contexts to develop microscopic explanations.
This textbook is designed for the freshman-level Introductory Chemistry course that does not have a chemistry prerequisite and is suitable for either a one-semester course or a two-semester sequence. The book targets introductory courses taken by non-physical science majors who may be in allied health, agriculture, or other disciplines that do not require the rigor of a science majorâ€™s General Chemistry course, or for students fulfi lling university liberal arts requirements for science credits. In addition, students who lack a strong high school science background often take the course as a preparation for the regular General Chemistry sequence.
FEATURES OF THIS TEXT
Learning theory indicates that we should start with the concrete, macroscopic world of experience as the basis for developing student understanding of abstract, microscopic concepts. This textbook follows a topic sequence typically found in traditional General Chemistry texts.
That is, macroscopic ideas about chemical behavior are discussed before descriptions of abstract, molecular-level concepts associated with electron structure. The macroscopic ideas that begin chapters or sections are grounded in real-life experiences. Where appropriate, the macroscopic to molecular-level progression of ideas is carried over to topic sequence within individual chapters or sections in addition to the general sequence of chapters.
Each chapter begins with a chapter-opening outline and an opening vignette that personalizes the content by telling a story about chemical phenomena encountered by students. These applications help students see how chemistry relates to their daily lives.
