Portland Community College | Portland, Oregon

After completion of this course, students will
1) Apply knowledge of mechanics and vectors to explain natural physical processes and related technological advances.
2) Use an understanding of elementary mathematics along with physical principles to effectively solve problems encountered in everyday life, further study in science, and in the professional world.
3) Design experiments and acquire data in order to explore physical principles, effectively communicate results, and critically evaluate related scientific studies.
4) Assess the contributions of physics to our evolving understanding of global change and sustainability while placing the development of physics in its historical and cultural context.
 

At the beginning of the course, the instructor will detail the methods used to evaluate student progress and the criteria for assigning a course grade.  The methods may include one or more of the following tools:  examinations, quizzes, homework assignments, laboratory reports, research papers, small group problem solving of questions arising from application of course concepts and concerns to actual experience, oral presentations, or maintenance of a personal lab manual.
The student will be evaluated on written tests covering both lecture and lab experiences, required lab reports, and on turned- in homework questions (verbal skills and reasoning in written format) and problems (quantitative in a few cases).
 

The instructor will be required to cover the goals and objectives listed in this Course Content Guide.  The Course Content Guides are developed by college-wide subject area faculty and approved by
