Catalog Description of the Course 

 

Biology 2401 and 2402                    8 semester hours

                                                                  

A course dealing with the anatomy and physiology of the various systems of the human body.  The first semester includes the cell, tissues, the skeletal system, muscular system, and nervous system. The second semester includes the blood and circulation, immune response and other defense systems, the respiratory, excretory, endocrine, reproductive, and digestive systems.  Fulfills the pre‑nursing requirement in human anatomy and physiology.  Three lecture and three laboratory hours per week.

 

Determination of Grades 

   

    The final grade of each semester will be determined upon an average basis.  Grading is on a 60 to l00 system as follows.

 

             Final Average               Course Grade

             90 ‑ 100                    A 

             80 ‑ 89                     B

             70 ‑ 79                     C

             60 ‑ 69                     D 

                < 60                     F

 


There will be four lecture examinations and three laboratory examinations.  All examinations have equal value and will constitute 75% of the final grade. A comprehensive final examination will make up the remainder of the final grade. Completion of the science module is also a course requirement. Students who miss an examination, and have a valid excuse, will be permitted to take a makeup examination.  All makeup examinations are given during final examination week or at a time that is convenient with the instructor.  Only one makeup examination is permitted.  At the end of the semester certain students may find themselves on the borderline between two possible grades (e.g. 79.75). The instructor will then assign a grade based upon his best judgement.  Such things as class attendance, attitude, participation in the laboratory, and effort expended on the science module, will be considered.  Any student missing three or more classes or who fails to take an examination  will not be considered for the higher grade.  At the end of the semester any student with a 90% or better average for  all seven  examinations  will be exempt from the final examination. 

 

 

Science Module

 

     Completion of the science module is a course requirement.  The science module consists of an essay (PSM1) and activities sheet (PSM2).  Both are located in the study center.  After you have completed the activities sheet return it to the study center director.  Students completing the science module by the sixth week will have five points added to their lowest test score.  There will be ten questions on the final examination concerning the science module.  Students who have previously completed the science module for another class will read several articles dealing with the nature of science (PSM4).  These are on reserve in the study center.  Upon completion of these articles, a one page written summary of each article will be completed and returned to the study center director.

Study Center  and Computer Center

 

Room 350 is the Biology Study Center and provides access to the computer center..  Students may study both lecture and laboratory materials at their own pace in the study center.  Computer, videotapes, laboratory, and reference materials are available.    Code letters represent the following types of materials.  The computer center is available for individual use at times when classes are not scheduled in it.

 

Class Attendance

 

Students are expected to attend all regularly scheduled lectures and laboratories.  A student missing the equivalent of two weeks of work (four TR or six MWF class days) will be dropped from the course unless previous arrangements have been made with the instructor.  Note that two tardies count as an absence. 

 

Tardiness 

 

All classes begin promptly at the designated starting time.  Students are expected to be in their seats at the beginning of the class period.  Two tardies will count as an absence.  Students returning late from class breaks during split sessions will be counted tardy.  Students are expected to remain for the duration of the class.  Any student leaving prior to class dismissal will be counted absent for the entire period.  The only exception will be emergencies that occur during the class or prior consent of the instructor. 

 

 

 

 


Classroom rules

 

1.          Eating, drinking, and gum chewing are strictly prohibited in the classroom.

 

2.          Cell phones and pagers must be turned off during class.

 

 

3.          Tape recorders are permitted, but not on days when examination results are being discussed.  Any student found recording an examination discussion session will be dismissed from the course with a failing grade.

 

4.          During examinations students are expected to keep their answer sheets covered at all times with the cover sheet provided.  Any student who fails to keep his or her answer sheet covered will automatically have ten points removed from their examination grade.

 

5.          Students are expected to remain in the classroom for the entire class period.  Any student who finds it necessary to leave the classroom while class is in session will not be permitted to return during that class session.

 

Student conduct

 

The highest standards of conduct are expected from all students. Actions by students that detract from the learning environment will not be tolerated. The instructor reserves the right to dismiss any student from class and/or the course who engages in behavior that is disruptive and/or detracts from the learning environment. Such behavior includes (but is not limited to) conducting private conversations during lecture and sleeping in class. Cheating on examinations in any form will result in automatic dismissal from the class with a failing grade.  The instructor may also recommend to the appropriate Dean that the student(s) involved be expelled from San Antonio College.

 

General Information 

 

Examinations will normally consist of multiple choice and/or completion type questions. Essay questions may sometimes be included.  Exams will usually consist of from 60 to l00 questions. The final examination will consist of l20 questions. All examination questions will be based upon the learning objectives which are included with this syllabus.   Students are encouraged to ask questions in class when a point or concept needs clarification. Students who are having difficulty are encouraged to seek help from the instructor either during scheduled office hours or by appointment.

 

 

 

 

Text Objectives 

 


At the end of each set of learning objectives you will find a section entitled "text objectives."  These are objectives based upon material found in the text book but not discussed in lecture. The instructor will not answer questions in class concerning these objectives .  The instructor will discuss these objectives on an individual basis after class.

 

Study Advice 

 

The subject of this course is very interesting and one that is very relevant to allied health careers and everyday life.  It is a complex subject with a technical vocabulary and numerous principles which must be mastered.  Below you will find a series of suggestions which if followed will guarantee successful completion of the course.

 

l.  You have been furnished a lecture outline along with reading

assignments.  Before each lecture read over the outline so that you will be aware of the topics to be covered.  Use it as an organizational skeleton to arrange your notes around.  Use it  in conjunction with the learning objectives as a form of review.

 

2.  Read your text assignments before you come to class.  It will surprise you how much more you will understand of what is subsequently discussed in lecture.

 

3.  Study very carefully the learning objectives.  All examination questions will come from these objectives.  Mastery of the objectives will insure mastery of course material.  Use the objectives in conjunction with the old examinations which are on file in the study center.  In this way you will begin to understand how examination questions are developed from the objectives.  You will find it useful to write out the appropriate responses for each objective.

 

4.  Study every day.  Do not wait until the night before the examination or you will be overwhelmed.  A large amount of materials covered in this course but if you master it as it is covered you will have minimum difficulty.  After lecture read through your notes: check your organization.  Do you understand everything that was presented?  Read the text assignment again (assuming your read it the first time).  Examine the learning objectives and see which ones were covered in that particular lecture.  After several days read through your notes again.  By doing this on a continuous basis you will find that the material becomes fixed in your mind.  It takes such a very little time to read through your notes on a daily basis but the results can be dramatic.


 

5.  If you need help, get it.  Ask questions in class.  Seek out the instructor after class for additional help.  San Antonio College has peer tutoring services available.  Consult with your instructor if you feel you need a tutor.

        

6.  Form a study group.  Three to five students is usually a good size.  Work together, quiz each other, and explain concepts to each other.  Studies have shown that people retain only about ten percent of what they read, but up to ninety percent of what they explain to someone else!

 

Additional reading

 

While your textbook is designed to provide you with basic information concerning this subject, it is by the nature of the printing process, usually out of date by the time it is first published.  It is for this reason that weekly or monthly journals are the main method by which new scientific discoveries are disseminated.  There are literally thousands of biomedical specialty journals.  Most of these are designed for specialists in a given area of research or clinical practice.  The journals in the following list are more general in nature and are readily available at most newsstands and public libraries.  Students wishing to stay abreast of scientific developments should make it a habit to peruse one or more of these journals.

 

1.  Discovery - This is a popular monthly journal of general science.  Frequently topics of a physiological interest are covered.  Available at most newsstands, libraries, and by subscription.

 

 

2.  Natural History - This journal is published by the American Museum of Natural History.  It contains a wide variety of articles of biological interest.  It is a monthly publication which is available at most news stands, libraries, and by subscription.

 


3.  Science - This is the journal of the American Association for the Advancement of Science, the largest member scientific society in the world.  It contains technical articles which are usually of interest only to specialists, but it also contains review articles and research news written for all audiences.  Although it covers all areas of science it has a strong biomedical emphasis.  If any discovery in science appears to have major significance, it will appear somewhere in "Science." Published weekly, this journal is available in most libraries.

 

4.  Science News - This little weekly is only about twelve pages long but manages to cover most of the important happenings in science.  Written in an engaging and lively style, this may be thought of as the "Readers Digest" of popular science.  While this publication is available at most libraries, a subscription is a must for anyone truly interested in keeping current in science.

 

5.  Scientific American - This excellent monthly magazine represents a hybrid of a technical journal and a popular magazine.  Each article is written by an expert in the field and represents the current status of knowledge for the subject covered.  While each article can supposedly be understood by any literate and educated person, some can be tough going for the non-specialist.  This one is always worth looking through. Available at libraries, newsstands, and by subscription.

 

 

World Wide Web and Internet

 

Students have access to the internet and world wide web at both the library and in the biology computer center.  There is a wide variety of information available about the subject of this course on line.

LABORATORY

 

General Information 

 

   l.   Laboratory attendance is mandatory.  Students will have one

        point removed from their  laboratory test grades (all three 

        tests) for each laboratory session missed without a valid 

        excuse.

 

   2.   Laboratory examination are practical in nature and based upon

        the learning objectives included with this syllabus.  Each

         laboratory  examination will be fill‑in‑the‑blank with

         occasional short essay questions.  Three such examinations 

         will be given.      

 

    3.   Room 350 is the biology study center. Students will find 

     laboratory materials, books, slides, specimens, and other study   aids.  Most of the materials which you will be tested on can be   found in the study center.

 

4.   The laboratory involves the use of dissections of animals and           animal parts as well as experiments using human and/or animals.          Students are expected to participate in all of these                    activities.  Students who refuse to participate can expect to           have their  course grade reduced appropriately as determined by          the  instructor.

 

    5.   Your laboratory manual has a web site for review and testing on          the exercises.  The address is as follows.
