AP PhysicsC Mech Practice Exam 2008

AP PhysicsC Mech Practice Exam 2008

The actual AP Physics C Exams are administered in one session, Mechanics first followed by Electricity and Magnetism. Students taking only one of the exams will have the most realistic experience if both sections are completed in one session. Similarly, students taking both Physics C exams will have the most realistic experience if both exams are completed in one session and a complete morning or afternoon is available to administer them. If a schedule does not permit one time period for administration, it would be acceptable to administer Mechanics on one day and Electricity and Magnetism on a subsequent day, or to further break things up and administer Section I and Section II of each exam on subsequent days.

Students are permitted to use four-function, scientific, programmable, or graphing calculators on parts of this exam. Review the section “Calculator Policy” on pages 40–42 of the 2011-12 AP Coordinator’s Manual. Before starting the exam administration, make sure each student has an appropriate calculator and any student with a graphing calculator has a model from the approved list on page 42 of the 2011-12 AP Coordinator’s Manual. If a student does not have a calculator or has a graphing calculator not on the approved list, you may provide one from your supply. If the student does not want to use the calculator you provide or does not want to use a calculator at all, he or she must hand copy, date, and sign the release statement on page 41 of the 2011-12 AP Coordinator’s Manual. Rulers and straightedges may be used for the entire exam. Since graphing calculators can be used to store data, including text, proctors should monitor that students are using their calculators appropriately. Attempts by students to use the calculator to remove exam questions and/or answers from the room may result in the cancellation of AP Exam scores.

5. Strict rules regarding significant digits are usually not applied to numerical answers. However, in some cases answers containing too many digits may be penalized. In general, two to four significant digits are acceptable. Numerical answers that differ from the published answer due to differences in rounding throughout the question typically receive full credit. Exceptions to these guidelines usually occur when rounding makes a difference in obtaining a reasonable answer. For example, suppose a solution requires subtracting two numbers that should have five significant figures and that differ starting with the fourth digit (e.g., 20.295 and 20.278). Rounding to three digits will lose the accuracy required to determine the difference in the numbers, and some credit may be lost.

During the administration of Section II, students may have no more than two calculators on their desks. Calculators may not be shared. Calculator memories do not need to be cleared before or after the exam. Students with Hewlett-Packard 48–50 Series and Casio FX-9860 graphing calculators may use cards designed for use with these calculators. Proctors should make sure infrared ports (Hewlett-Packard) are not facing each other. Since graphing calculators can be used to store data, including text, proctors should monitor that students are using their calculators appropriately. Attempts by students to use the calculator to remove exam questions and/or answers from the room may result in the cancellation of AP Exam scores.

Before Distributing Exams: Check that the title on all exam covers is Physics C: Mechanics. If there are any exam booklets with a different title, contact the AP coordinator immediately. Students are permitted to use rulers, straightedges, and four-function, scientific, or graphing calculators for this entire exam (Sections I and II). Before starting the exam administration, make sure each student has an appropriate calculator, and any student with a graphing calculator has a model from the approved list on page 49 of the 2016-17 AP Coordinator’s Manual. See pages 46–49 of the AP Coordinator’s Manual for more information. If a student does not have an appropriate calculator or has a graphing calculator not on the approved list, you may provide one from your supply. If the student does not want to use the calculator you provide or does not want to use a calculator at all, he or she must hand copy, date, and sign the release statement on page 47 of the AP Coordinator’s Manual.

The Effect of Professional Development on Middle School Teachers' Technology Integration: An Action Research Study

The Effect of Professional Development on Middle School Teachers' Technology Integration: An Action Research Study

posttest method, students were assessed before and after the semester in which students learned Mechanics or Electricity and Magnetism. In Mechanics, students completed the 2015 AP Physics C: Mechanics practice exam, FCI, and MBT assessments; in Electricity and Magnetism, students completed the 2015 AP Physics C: Electricity and Magnetism practice exam, BEMA, and EMCA assessments. During each semester, I implemented Modeling Instruction with AP Physics C: Mechanics or Electricity and Magnetism content (see Appendices A, B, and C for further information). Each unit of content began with a paradigm laboratory, providing an experience for students to create an initial model. Students moved through the Modeling Cycle by performing practice problems and completing more laboratory activities, adding new information to their initial model. Near the end of each unit, students used a whiteboard to summarize their learning into a fully-constructed model; students shared their whiteboards to compare fully-constructed models. Students finished each unit with a written summative assessment containing multiple-choice and short answer problems; some units also had students perform a summative laboratory practicum. The cycle was repeated with a new unit of content, leading to the development of models in Mechanics and Electricity and Magnetism.

CALCULUS REMEDIATION AS AN INDICATOR FOR SUCCESS ON THE CALCULUS AP EXAM

CALCULUS REMEDIATION AS AN INDICATOR FOR SUCCESS ON THE CALCULUS AP EXAM

There are also certain biases that may have detracted from greater student success on the AP Calculus AB exam. During the eight years of the remediation implementation, the impact of Common Core at the elementary level may have had a negative impact on students’ level of understanding on basic concepts, which would lead to gaps in the mathematical foundation that students develop. These gaps follow the student to high school and may detract from the overall understanding of concepts in prerequisite classes for Calculus as well as in the Calculus class itself. During the last five years of this study the seat time that students had in class dropped by ten minutes per school day, or for a cumulative amount of about two weeks of class time. Less time in class means less time to understand the material presented. Along with the remediation program, these positive and negative biases must be looked at as possible factors that may affect the change in success for the group of students over the eight years of this study.

If any students used extra paper for a question in the free-response section, have those students staple the extra sheet(s) to the first page corresponding to that question in their exam booklets. Complete an Incident Report. A single Incident Report may be completed for multiple students per exam subject per administration (regular or late testing) as long as all of the required information is provided. Include all exam booklets with extra sheets of paper in an Incident Report return envelope (see page 60 of the 2015-16 AP Coordinator’s Manual for complete details). Then say:
