Course Introduction

My educational philosophy is that you learn best when you are actively engaged with the subject through activities such as reading (and answering questions about what you read), discussing, experimenting, and solving problems. Lectures are useful for motivation, but for most students listening to lectures and copying lecture notes is an ineffective method to learn. It's when you study individually (or sometimes in a small group), think deeply about the subject, and subsequently dialogue with classmates and the professor that you learn the most. My role as the professor is to create an environment that promotes active-learning, to assess your learning, and to provide guidance and mentorship along the way.

One does not receive knowledge, one BUILDS knowledge. This puts the burden on you to build your knowledge and the burden on me to give you the tools and blueprints. TOGETHER, we'll accomplish our goals.

Key to the web site

The outline at the left side of each page leads you consecutively through the course. There are navigation links at the top of each page (in the gray bar) and below the body of the text of each page that take you to the next topic. Simply go from one topic to the next.

Along the way, you will be asked to stop and do things such as read a chapter or section from the textbook, submit a homework assignment, or do a lab activity. The key below is used to alert you to certain tasks.

Do something such as a survey, an activity, worksheet, or tutorial.
Read a chapter or section from our textbook.
Do an experiment.
Submit homework.
Watch a video tutorial.
Email the professor or classmates.
Answer a question.


There are often questions interspersed throughout the text, like the one shown below. Answer these questions because they help you to test your understanding of what you read on the web site.

Are the stars beautiful on a clear, dark night?


At the bottom of each page is a chance for you to give feedback. It is completely anonymous (because there is no login for this web site), and your feedback will help me improve the course. Go ahead and submit feedback on this page, just to see if it works!






Note: to keep spammers out, the feedback form requires you to type the class name, such as PHY1050, in order to submit feedback.

This is from Dr. Titus. I'm excited to observe some planets, stars, nebulae, and galaxies this semester.
