Rationale

 

This course (second in a sequence of two)  is appropriate for students expecting to apply to one of the health care professional schools / programs (e.g.   medical, physical therapy, pharmacy, dental, etc.), and also for students in certain technical programs which require  a year of non-calculus based physics (e.g. electronics, computer service, architectural drafting, etc.). It is also appropriate for any student that wants to increase his/her knowledge of basic physics   using only algebra and right angle trig

C  : EXAMINATIONS:

      There will be 3 major exams given  in advance during the semester.  No

       make-up exam will be given .  Absence from these exams will result in a zero grade.  A comprehensive final will be administered during final exam week. This is a requirement of the course. Exam Questions will be asked from deductive reasoning from the material presented in Class, Home Work and Reading assignment.

 

HOMEWORK:

 

Homework assignment will consist of:

 

1 .   Reading sections in the text

 

2.   Answering questions

 

3.    Problems

 

           It is essential for students to do assignments on a daily basis.  Selected problems will be discussed in the class as time and demand permits.  The reading assignments are made in advance of the lectures that cover the reading material.  The lectures are designed to reinforce the students reading not for the students to learn the entire course from the lectures. It is extreamly important for the students to carefully and perceptively read the assignments before the lectures. Some elementary material that needs little explanation will be assigned for reading and not covered in the class.

 

 

 

PREPARATION AND PREREQUISITES:

 

           Students are required to have completed the appropriate prerequisits Math/Physics courses or their equivalent to be enrolled in a course.  Students who have not completed the prerequisite courses are ineligible for enrollment in a course and will not be given a final grade if they do not withdraw.  Students should either be concurrently enrolled in the required Math course or have completed it or an equivalent course.  Students are required to have a working knowledge of the topics involved in the prerequisite courses   and all their prerequisites at least at the level of having passed the  courses at the B level.  If the student feels insecure in his/her depth of knowledge in these areas it is recommended that he/she immediately undertake a brief but thorough review of these subjects in lectures, but the student will be responsible for knowing the material. All the exam problems will be similar to the homework assignments, the example problems in the book or example problems worked out in the lectures.

 

 

 

 

TEST PREPARATION

                The amount of time you study for a physics test is less important than how  you spend your time studying.   It may seem obvious to some, but you should spend your time studying for a test the same way you will be taking the test.   If you are to play a musical instrument without looking at the music, that’s the way you would practice it.   Therefore it makes sense that, if you are expected to solve problems on a physics test, you should study by solving as many problems as you can.   Reading  the chapter before you attempt  to solve problems is also necessary  and effective at teaching you how to solve problems.  Take good notes in the class and rewrite them at the end of the day after reading the chapter. These notes will come in handy for review before the test. When you do homework problems keep them in a note book for review for the exams.

                My physics tests will consist of some combination of free-response ( problems ) questions and multiple-choice questions.    They will also include a combination of quantitative problems (where you will use equations to compute an answer) and qualitative or conceptual problems (where you will be asked to describe a situation or compare and contrast two situations for example).  

                Again, to practice for the quantitative problems, either free-response or multiple-choice, you should solve problems.   There are several ways to do this:
1)        Use the example problems in the book since you have the solutions.
2)       Solve the problems at the end of the chapter, given for home work
4)       Make up problems like the ones we did in class and solve them.  Come to me for help if you need answers.
Remember to solve the problems in the same conditions you will take the test.    If you are constantly flipping through the chapter as you try to solve problems, you are using a crutch which will not be available to you during the test.   You should solve the problems using only a pencil and calculator (and any allowable equation sheet);   you should resort to looking in the book only after you have been unable to solve the problem for some time. 

To review for the conceptual parts of the test, there are several strategies:
1)        Review your chapter notes and outline.  Make sure you know the definitions of all of the new words in the chapter.   Make sure you know the units of each new quantity.
2)       Answer the conceptual questions at the end of the chapter: they are usually in their own section entitled “Questions”, right before the quantitative “Problems” section. You may want to engage your classmates (by making a study group) in a discussion of these questions: arguing your point strengthens your understanding of the material.   It is often said that you only understand something after you teach it to someone else.    
3)       Take each of the major equations in the chapter and write a paragraph that explains what it means and what its implications are.       

 It’s not how long you study for a test, but  how you study that is important.  These hints should help make your study more effective, but everyone is different and everyone learns differently. Try different techniques until you find one that works for you. Then stick with it .Keep notes of all the work that you do during the semester  in one note book, it will be easier to review before the tests.

 Psychological research has shown that repeated practice, practice, practice is crucial for excellence. Rote repetition is very important. It is impossible to become proficient at a mental task without practice. If you repeat the same task again and again, it will eventually become automatic. Your brain will literally change so that you can complete the task without thinking about it. Once this happens, the brain has made mental space for higher order operations, like for exploring the emotional content of a piece of music and not just playing the notes , for interpreting literary works and not simply decoding their words. Brain scans of experimental subjects who are asked to execute a sequence of movements show that as the sequence is repeated the parts of brain associated with motor skills become less active allowing brain activity to shift to the areas associated with higher level thinking and reflection. Remember everything becomes fun when you are good at it.

COLLEGE POLICIES FOR COURSE SYLLABI:

 

 

CCBC CODE OF ACADEMIC INTEGRITY

 

Academic honesty is expected of all students.  Work submitted by students as their own must be their own and materials taken from any other source must be clearly identified as such.  Falsification of data, plagiarism, copying from others in class, obtaining advance information about exams, and other violations of academic honesty are not acceptable.  The usual penalty for academic dishonesty is failure on the paper or exam or failure in the course, as determined by the instructor.  The instructor may recommend a more severe penalty, such as dismissal from a program or from the College.

 

CCBC WRITING POLICY

 

The college recognizes that clear, correct and concise use of language is a characteristic of an educated person.  Instructors should consider the quality of writing in determining a grade for a written assignment.  In some instances, poor writing can be a sufficient cause for a failing grade on a paper, and in extreme cases, a failing grade in a course.

 

CCBC ATTENDANCE POLICY

 

All students are expected to attend class regularly and punctually in order to derive maximum benefit from instruction and to contribute to learning in the classroom.

 

Each faculty member will determine the specific attendance policy for each course and will monitor attendance accordingly.  At the faculty member’s discretion, absence from class may be the basis for academic failure.

 

 

Students are encouraged to seek help from their instructors whenever they encounter academic difficulty (either during scheduled office hours or by appointment).  In addition, the Student Success Center in E312 has information about free tutoring provided.  Stop by or call for more information (410-780-690).

 

 

 

SNOW AND EMERGENCY CLOSING POLICY

 

Should it become necessary for the College to close or alter its times of operations, announcements will be made after 6:30 a.m. on WBAL radio (1090 AM) or you can call 410-682-6000.  Should the College’s opening be delayed, faculty and students are expected to be where they would normally be at the announced opening time.
