#### Course Description

#### Addendum to Course Description

This is a calculus-based physics course required for students majoring in engineering, physics and chemistry. The course is transferable to other baccalaureate engineering programs. Students should be aware of the program requirements of the institutions to which they wish to transfer. This course conforms with the Oregon Block Transfer program.

#### Intended Outcomes for the course

After completion of this course, students will

1) Apply knowledge of electricity and magnetism to explain natural physical processes and related technological advances.

2) Use an understanding of calculus 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.

#### Course Activities and Design

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

#### Outcome Assessment Strategies

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, final exam, and labs.
