Portland Community College | Portland, Oregon

This is an pre-calculus introductory physics course for pre-medical, pre-dental, pre-chiropractic  and pre-physical therapy students and students working toward a degree.  Study topics include electricity, magnetism and modern physics.  This course meets college transfer, Oregon Block Transfer and program requirements as listed above.  This is an algebra-based physics course required for students majoring in biology, pre-medicine, pre-dentistry, architecture, and many other degree programs.  The course is transferable to colleges or universities.  Students should be aware of the program requirements of the institution to which they wish to transfer.  

After completion of this course, students will
1) Apply knowledge of electricity, magnetism, and modern physics to explain natural physical processes and related technological advances.
2) Use an understanding of algebraic 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.

Principles and techniques are presented through lectures and  class demonstrations.  Students must register for lecture and  one lab.  Laboratory work will be performed in order to clarify certain facts in the lecture materials.  

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.   Specific evaluation procedures will be given in class.  In general, grading will be based on accumulated points from homework assignments, tests, a final exam and labs.
