Foundations of Astronomy, 14th edition, by Michael Seeds and Dana Backman, emphasizes the scientific method throughout as it guides students to answer two fundamental questions: What are we? How do we know? In addition to exploring the newest developments and latest discoveries in the exciting field of astronomy, authors Michael Seeds and Dana Backman discuss the interplay between evidence and hypothesis—providing both factual information and a conceptual framework for understanding the logic of science. The WebAssign component offers tutorials, assessment problems, conceptual questions, and interactive components. The variety of question types offers options for both for qualitative and quantitative approaches to teaching astronomy.

Many of the questions provide scaffolding to build skills and confidence in the use of simple algebra, geometry, and proportional reasoning to solve astronomy problems. Many provide targeted feedback to address specific student errors. Finally, several have interactive elements (above all the Virtual Astronomy Laboratories, two of which appear at the end of this Sample Assignment).

Features:
  • Virtual Astronomy Laboratories (VAL) can be assigned as a standalone activity or as part of a larger learning experience. VAL incorporates real astronomical data, simulations, and other interactive elements, offering students the opportunity to experience astronomy as a scientist. Targeted feedback guides students in revising any incorrect answers.
  • Optimized Problems offer randomized parameters and provide targeted feedback to students who have incorrectly answered any part of the problem.
  • Tutorials coach the student through the steps of problems. These highly structured, scaffolded learning activities give strong support to the student with emerging or dormant quantitative-reasoning skills.
  • Animation Tutorials present rich concepts using animations, interactive figures, or other multimedia elements, and then assess student learning with a variety of item types.
  • Problems appear in the back of textbook chapters, though numbers and contextual details may be randomized for a customized learning experience.
  • General Problems are multiple-select (MS) items, in which several choices may be correct. They invite students to synthesize descriptive knowledge about a particular topic.
  • Review Questions are adapted from the textbook questions and provide opportunities for test prep and formative assessment.
  • Read It links under each question quickly jump to the corresponding section of a complete eBook.
