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.
Students can bring a simple scientific calculator for the exams.
Cell Phones/Palm pilot or any other electronic devises of any kind will
not be allowed during the exams .
HOMEWORK:
Homework assignment
will consist of:
1 .
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.
LABORATORY WORK:
Report should be done neatly. Late reports will not be graded.
.
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.
CELL PHONES AND PAGERS:
Interruptions of class by ringing cell phones and pagers will not be tolerated.All cell phones and pagers must be turned off during class and kept in the book bag .If due to an emergency situation you need to leave your phone on , you must have my permission and turn it to silent mode. Text messaging and IM is not permitted during class time .Computers are not permitted in the classroom

COLLEGE POLICIES FOR COURSE SYLLABI:
Log on to My CCBC
Look under My SyllabiPolicies
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.
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.
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
CONTACT STATEMENT:
Students should first attempt to take concerns to the faculty member. If students are unable to resolve course-related concerns with the instructor, they should contact Katherine Van de Wal, Physical Science Campus Coordinator, at 443-840-2685, kvandewal@ccbcmd.edu, room CTMP-115 on the Essex campus
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.
Attendance policy
Attendance at each face-to-face class and lab is essential. Please be on time. Students with a legitimate problem about attendance should discuss the situation with their instructor.
NOTE: The deadline for withdrawing from a course or changing to an audit for the Spring, 2010 semester is April 12. Failure to officially withdraw from a class you have stopped attending may result in an "F" grade. The SIMON online system is unavailable after the first day of classes, and as such, an official change of schedule form must be completed and processed by the Records and Registration office for any schedule changes.
COURSE REPEAT POLICY
Policy on Repeated Courses, as of the 2006-2007 CCBC online catalog states, is as follows: Students may be restricted from registering for a course for a third or subseqquent attempt. When a student repeats a course, only the higher grade is computed into the Quality Point Average (QPA). All grades will remain on the student’s transcript. Before a student is permitted to register for the course for a third or subsequent attempt, the student must have the permission of the academic dean (or his/her designee) responsible for the course. Before a student may repeat a developmental course that he or she has failed twice, the student’s record must be reviewed by a support team which will make recommendations regarding enrollment.” Please note: The instructor does not have the authority to grant permission to register for a third attempt at the course.
In accordance with the Americans with Disabilities Act, CCBC is committed to providing an environment that is conducive to learning for all students. Any student who is disabled and requires special accommodation should contact the appropriate campus as follows:

Code of Academic Integrity
For the College to make its maximum contribution as an institution of high learning, the entire college community must uphold high standards of integrity, honesty, and ethical behavior. In seeking the truth, in learning to think critically, and in preparing for a life of constructive service, honesty is imperative. Each student has a responsibility to submit work that is uniquely his or her own, or to provide clear and complete acknowledgement of the use of work attributable to others. To these ends, the following actions are expected of students:
· Complete all work on exams without assistance.
· Follow the professor’s instructions when completing all class assignments.
· Ask for clarification when instructions are not clear.
· Report to the instructor any unauthorized information related to an exam.
· Provide proper credit when quoting or paraphrasing.
· Submit only one’s own work.
Students who do not accept responsibility for the integrity of their own work will experience sanctions, including a written reprimand, failure of the assignment, failure of the course, and/or dismissal from the program. For repeat and extreme offenses, the College reserves the right to suspend or expel students.
The College recognizes that clear, correct, and concise use of language is characteristic of an educated person. Therefore, whenever possible, faculty members in all disciplines should require written assignments in their courses in order to encourage effective writing by their students. Also, instructors should consider the quality of writing in determining a grade for a written assignment. Poor writing can be a sufficient cause for a failing grade on a paper and, in extreme cases, a failing grade in a course.
In the event that the college (or a specific campus) opens late due to weather-related or other emergency conditions, classes will commence at the announced opening time and resume the normal schedule thereafter for the remainder of the day. Faculty, students, and classified staff should report to wherever they would normally have been at the announced opening time. **
Students and faculty engaged in field placement programs (such as internships, clinical placements, etc.) should discuss the handling of emergency situations at the beginning of the placement period. Both the requirements of the program and the safety of persons involved should be considered in planning a course of action in those cases where students are expected to report to off-campus locations.
** For example, if you had a class that began at 9:35 and the college opened at 10:00 because of snow, you would report to your 9:35 class at 10:00.
When the college closes because of severe weather or emergency conditions, announcements of class cancellations are made on local radio and television stations and the college website (www.ccbcmd.edu). Closings and delays will also be recorded on the campus weather lines:

Arrangements between the student and the faculty member(s) for the student to make up missed assignments or tests must be made in advance of the religious holiday, at the initiation of the student.
STUDENT E-MAIL ACCOUNTS
CCBC has joined the ranks of the very few community colleges in Maryland who provide email accounts to all credit students. Each student who is registered in credit classes now has an email account and up to 5 Mb of storage in their mail box. This account will not be deleted even if the student graduates or leaves CCBC for any reason.
For information about the system and how students can determine their email address, go the CCBC Home Page and click on “Student Email”. From here students can find their email address, get to an on-line user manual and access instructions on how to forward the CCBC email to the system of choice (AOL, Comcast, Hot Mail, etc.)
