Шаблон:Short description Шаблон:Advanced Placement Advanced Placement (AP) Physics 1 is a year-long introductory physics course administered by the College Board as part of its Advanced Placement program. It is intended to proxy a one-semester algebra-based university course in mechanics. Along with AP Physics 2, the first AP Physics 1 exam was administered in 2015.
In its first five years, AP Physics 1 covered forces and motion, conservation laws, waves, and electricity.[1] As of 2021, AP Physics 1 includes mechanics topics only.[2]
History
The heavily computational AP Physics B course served for four decades as the College Board's algebra-based offering. As part of the College Board's redesign of science courses, AP Physics B was discontinued; therefore, AP Physics 1 and 2 were created with guidance from the National Research Council and the National Science Foundation.[3] The course covers material of a first-semester university undergraduate physics course offered at American universities that use best practices of physics pedagogy.[4] The first AP Physics 1 classes had begun in the 2014–2015 school year, with the first AP exams administered in May 2015.
Curriculum
AP Physics 1 is an algebra-based, introductory college-level physics course that includes mechanics topics such as motion, force, momentum, energy, harmonic motion, and rotation; The College Board published a curriculum framework that includes seven big ideas on which the AP Physics 1 and 2 courses are based, along with "enduring understandings" students are expected to acquire within each of the big ideas.:[5]
Questions for the exam are constructed with direct reference to items in the curriculum framework. Student understanding of each topic is tested with reference to multiple skills—that is, questions require students to use quantitative, semi-quantitative, qualitative, and experimental reasoning in each content area.
