AP Physics C: Mechanics Syllabus Fall, 2009 Mr. Allen Hankla Physics is not just a collection of equations. It is the search for the basic principles behind the equations. This calculus based, college level, physics class will introduce some of those basic principles in the context of mechanics. Additionally, this course prepares students for the College Board AP Physics C: Mechanics exam. The topic list, depth of understanding, and pace are intended to emulate a freshman college physics course for engineering or science majors. Emphasis is placed on developing student problem-solving skills and understanding, rather than rote memorization of equations and problem-specific strategies. Each unit during the semester will have the same general flow: First, you will explore each new topic in a way that encourages curiosity and questions. This exploration will include discussions of thought experiments, problem-solving activities, and conducting guided-inquiry based labs wherein you will be given a goal and minimal instruction as to how to achieve it. The labs and their write-ups are designed to encourage your exploration and understanding of the topic, enhance your understanding of the process by which new physical insights are gained, practice working in groups, and teach effective communication skills. Normally, block days (1.5 hrs) will be used for the labs planned this semester. During these explorations, I will ask you questions to assess your prior knowledge of the unit topics in order to be sure I don’t repeat things you already know and instead use our time together to address things you don’t yet understand. Once you are familiar with the basic ideas of the unit, we will then address the underlying concepts, often through a teaching structure called think-pair-share wherein you record your understanding of a concept then explain it to a partner and work out any discrepancies and then your group shares your thoughts with the class. I use this structure because I believe that the best way to be sure you understand something is to explain it to other people; this also gives me a chance to address any misconceptions that you or the class have about the topic. Homework will be assigned that will allow you to test your understanding of the topic, apply your understanding in specific contexts, extend your understanding beyond a basic level, and/or start thinking about the next day’s topic. The end of the unit will generally consist of a written assessment of your understanding. Each day of instruction will also have its own flow: I will present daily ‘Do Now’ problems on the projector which I expect you to start working on before the bell rings. These problems are designed to either reinforce the previous day’s lesson or to encourage you to think about a topic we will study in the current day’s lesson. After we discuss the ‘Do Now’ problem solution, we will start the lesson for the day. This lesson may involve a demonstration, mini-lecture, individual or group problem solving, individual or group problem creation, class discussions, student presentations, self- or peer-grading of problem solutions, and any other student-centered teaching strategies that we find will increase your understanding. At the end of the lesson, with about 5 minutes of class time left, I will present you with a Closure activity which is designed to give you time to process the day’s lesson. This Closure may involve a simple application of the day’s lesson, a start on the homework, a self-reflection on your strengths and weaknesses in understanding, or an extension of the lesson. I expect you to work on the Closure until the bell rings. We will use the following book: David Halliday, Robert Resnick & Jearl Walker. Fundamentals of Physics.
