Course Description AP Physics 1 is the first of a two year sequence that is designed to prepare students to take the AP Physics 1 examination. This course is organized around six big ideas combining together the fundamental science principles and theories of a general physics college course. It begins by integrating the use of trigonometric functions into Algebra-Based Physics topics of mechanics, waves, sound waves and electricity. This allows students to solve problems with vectors that are oriented at arbitrary angles; rather than just parallel or perpendicular to one another. This course emphasizes problem solving in the context of the principles of physical laws and principles; as well as the ability to apply that knowledge and skill to phenomenon in either an experimental or theoretical setting. Great attention is given to strengthening and reinforcing the natural connections between the sciences and real world. Students will be involved in problem solving, inquiry-based laboratory activities on an individual, small group and large group basis. Through this process the ability to read and understand problems, break them down into their component parts and then create and present solutions will be developed. About 25% of instructional time will be spent on hands-on laboratory activities with an emphasis on inquiry-based investigations. [CR5] Much of the work done in the laboratory will include the gathering of data through low-tech and high-tech (PASCO electronic sensors) lab investigations. That data will be configured by the students using the PASCO software and then analyzed using that software as well as a number of compatible programs, including Word and Excel. Through this process both analytical techniques as well as technological capability will be developed. III. Big Ideas for AP Physics 1 Big Idea 1: Objects and systems have properties such as mass and charge. Systems may have internal structure. Big Idea 2: Fields existing in space can be used to explain interactions. Big Idea 3: The interactions of and object with other objects can be describe by forces. Big Idea 4: Interactions between systems can result in changes in those systems. Big Idea 5: Changes that occur as a result of interactions are constrained by conservation laws. Big Idea 6: Waves can transfer energy and momentum from one object to another without the permanent transfer of mass and serve as a mathematical model for the description of other phenomena. IV.

They will present this information a partner in class for critique, describing the inaccuracies both qualitatively and quantitatively. VII. Course Assessment Formative assessments are done by the teacher in order to assure that the students understand the material that has been taught. These occur during class and divide into two categories. The first category is ungraded and consists of student participation, student responses to questions, observed student-student interactions and homework completion. The second type of formative assessment is graded and consists of quizzes, based on previously discussed homework assignments; quests, which are full period assessments that check a broader set of problems at the same level of difficulty as quizzes; and reading quizzes, which check to see if students have been completing reading assignments. Altogether these assessments represent about 20 - 30 % of the marking period grade. Summative assessments take the form of unit tests, midterms and finals. These are all given in the same form as the AP exam; half multiple choice and half free response. The multiple choice questions are conceptual in nature while the free response section involves solving multistep problems; often taken from prior AP exams. Unit tests comprise about 50-60% of each marking period grade. The midterm and final exam each represent 10% of the full year grade; combined they equal a marking period grade. The intention is for identical summative assessments to be given to all the students in the course on the same day, regardless of their teacher. This is to encourage students to study together in groups, with or without a teacher, to advance their skill and understanding. Laboratory work is graded and typically represents about 20% of each marking period grade. The grade is divided evenly between the work done in the lab, based on teacher observation, and the lab report. 6 VIII. Textbook/Teaching Resources Progressive Science Initiative AP Physics 1 digital textbook course documents from the New Jersey Center for Teaching and Learning found at https://njctl.org/courses/science/ap-physics-1/, published in 2014. This digital textbook includes SMART Notebooks Presentations, homework, labs, unit plans and assessments. [CR1] Laboratory Software: PASCO IX. Methodology Lecture Use of this method will be limited to the introduction of new topics and will be of short duration, typically no more than 10 minutes at a time. Many classes will not include this component at all. The students will need to use their visual, listening, writing skills and organization skills to benefit from this part of the course. Students will be required to keep complete and organized notes. Large group Problem Solving and Discussion Sessions The teacher will lead these sessions where students will actively participate in raising questions, answering questions and expanding upon topics. The entire class will work together to solve complex problems which test their understanding of the ideas being developed. The teacher will coordinate these sessions to ensure that all the students participate. This is vital in that this gives each student the opportunity to expand their understanding. By increasing the Zone of Proximal Development (ZPD) for all the students, they will be able to quickly advance their understanding. Small Group Problem Solving Sessions In these sessions a few problems will be given to the entire class and they will work in groups of 2 to 4 students to solve them. Once most of the problems have been solved, each group will present a solution to one of the problems to the rest of the class. Disputes and different approaches will be discussed in the Large Group format with the class taking the lead in determining the best approach. The teacher serves to chair the discussion. Once again this activity is designed to allow the students to quickly learn in an environment where their ZPD has been expanded. Hands-On Activities / Laboratory / Discovery Students participate in hands-on labs at least 25% of instructional time [CR5]. Each lab period is typically 86 minutes long, giving students the time necessary to take all data and begin analysis in groups. Students need to not only solve problems analytically but also apply those solutions to real hands on problems. These sessions are generally, but not exclusively, held in the physics laboratory and involve two to four students working together. The students will be asked to conduct experiments that either apply or develop new understandings. These will not be cookbook experiments, where the students simply walk through a procedure. Rather, these experiments involve gathering data and making analyses where the results are unknown to them, and sometimes even to the instructor. These labs will use actual physical apparatus, often with electronic probes to gather data and computers to conduct analysis. Whenever possible, they will be performed towards the beginning of each unit, affording the student the experience of discovering the concepts before they are formally taught by the instructor. One objective of each lab exercise is for each student to analyze their data using data and error analysis techniques in order to judge the accuracy and meaning of their results. Labs can be either teacher directed or student directed/open-ended. During a teacher-directed lab, the students are given instruction on the operation of lab equipment and guidance in the process of the experiment. Student-directed labs are when the students are given an objective and standard materials needed to conduct a lab. Students are allowed to create their own experimental design and collect data, which can be analyzed through graphical methods. After these labs, each student group must present their results to the class and/or other student groups to defend their results. They will also evaluate one other group's approach to the problem and offer a critique of their procedures and results. [CR8] 7 Each student will be required to keep their labs recorded in an organized lab notebook. This lab notebook will be kept by the students for the entire year and must include the completed labs including but not limited to the raw data tables and any notes made during the execution of the labs done in the course. [CR7]. Reading Students will be encouraged to develop the self-confidence and techniques required to learn directly from the text. The techniques needed to accomplish that will be discussed in class and reviewed from time to time. Readings will be assigned to either introduce or reinforce topics. In this way, classroom time is not spent reviewing every fact and detail for which the students will be responsible. Students will then be better prepared to participate and engage in active classroom discussion. The skill of being able to read and understand a text is so critical that great effort will be made to encourage students to develop it. In this vein, reading quizzes will be given from time to time to determine that students are completing their reading assignments. Homework problems Problems will be assigned every night so that students can apply the learning that was done during class that day. This will be checked by periodic homework quizzes that will be given the day after the assignment was due. In that way, student who made an honest effort but need to ask questions in class to reach a correct solution are not penalized. The homework quizzes are designed to test students are learning how to do these problems. This contrasts with collecting assignments, which can lead to copying rather than understanding. Field Trips Appropriate trips out of the school environment are an excellent way to show students that what they learn in classroom definitely relates to the world at large. Students are given a chance to see how ideas develop into real life situations and have real life applications. 8
