1. Course Objectives 

1.1. Introduction: Marine Mammals is one of the most fascinating subjects you can imagine.  Part of that is because humans seem to have a special (and sometimes fatal) attraction toward these animals; part because few groups of organisms present so many questions yet to be resolved in the realm of scientific inquiry.

The objective of the course is to introduce to the different species of marine mammals in the world and some of their most fascinating aspects of their behavior, physiological adaptations, and evolution on earth.  Also we will discuss the rocky relationship between humans and these creatures throughout history.  This course will be presented to you as a four-credit course. 

1.2. Methodology:  You will be trained in how to recognize the most important species of marine mammals and to further develop the knowledge and skills required of the research scientist, skills which are also required in many other professions.  Whether you enter graduate school, pursue a teaching career, or follow some other career path, you will be compelled to understand and integrate a large body of knowledge, to think analytically, identify and critically evaluate pertinent literature, to communicate effectively, and to work with others.

This class will be taught in a rather unusual way.  In addition to lecturing I use the Socratic method.  I call on you, I ask you a question, and you answer.  The idea is that you learn to teach yourselves through my questions. Through this method of questioning and answering, I want to develop in you the ability to analyze the vast and complex number of facts that have been accumulated and continue to be accumulated about these animals. At times you may feel that you have found the final answer.  Unlike TV contest shows, I will demonstrate to you that this is not the case.  You will never get the correct, complete, absolute, and final answer because the nature of science is that for each question you answer many more come up.  In my classroom there are always other questions after your answers.  You will feel like in an endless treadmill.  My questions are designed to spin the tumbles of your minds.  You will also feel that I am subjecting you to brain surgery with my questions serving like the fingers probing your brains.  In summary you will teach yourselves the facts, but I will train your minds.  At the end of the semester you will leave thinking like a top marine mammalogist … with a feeling of being a bit of a Renaissance person.

I set the bar high for the students. Otherwise, I'll never know what you're capable of — and neither will you.

This is how this course aims to develop those abilities.

A. Solid foundation in the knowledge of Marine Mammals.  You will be introduced to the content of the course in the classroom and in the laboratory. 

B. Application of scientific methods of inquiry, search and, critically read the scientific literature.  We will examine the diverse approaches used by researchers to uncover the basic concepts of the study of marine mammals.

C. Development of analytical thinking skills.  Few organisms are as familiar to humans as marine mammals and, at the same time, surrounded with so many scientific mysteries.  To make your approach as scientific as possible you will need to rely heavily on critical thinking.  The true test of understanding comes when you use your knowledge in different situations.

1.3. Expected Outcome:  By the end of the semester, you should have a general knowledge of the diversity of marine mammals as well as on the major topics relating to their biology such a communication, intelligence, sexual and social behavior, and conservation.  Additionally, you should have further developed your skills in planning a marine mammal research program, conducting field studies, analyzing information, and critically reviewing the scientific efforts of others.

3. Graduate Assistant

The graduate assistant for this course is Mr. Michel Conner who has already taken this course in the past.

 

 
 

4. Textbook and Supplies

4.1. The Textbook: There is not any recent textbook on marine mammals that satisfies the requirements of this course.  There are pretty (but often expensive, shallow, and outdated) books on dolphins and whales, or on seals, sea lions, and walruses.  So I will provide you with the draft of a textbook I have been writing by myself.

4.2. Other Supplies: I recommend that you obtain a CD-ROM or flash drive to download the electronic material I will be posting in Blackboard 8.

 
 

5. Other Resources

5.1. Library Resources: Our Library is very poor in terms of marine mammals literature. However, I have a private library with numerous books and more than 8,400 catalogued reprints on the subject and the CD-ROM and paper version of the complete collection of Marine Mammal Science, the most prestigious journal in the field.  You are welcome to use those resources in my office under my supervision.

5.2. Computer Resources:  All officially enrolled students have access to the E-mail system. I heavily use the system to communicate with you (up to several times a week).  Please check your email regularly for class announcements (and keep your email box as empty as possible).  You can also send me email to ask me questions or to engage in discussions with your colleagues.  Please avail yourself of this opportunity.  All course material will be posted in Blackboard 8.

 
 

6. Academic Approach

I give the best of myself in each one of my classes in order to offer you the opportunity to maximize your chances of learning lasting lessons in science.  I consider myself motivational, challenging, and enthusiastic.  I encourage questions during lectures and will stop lecture until you are satisfied that your question has been answered.  I greatly appreciate students who come to me for further discussion and inquiring.  Please do not hesitate to see me to discuss the subject as well any problem that may arise regarding class schedule and grading.  At the same time, I have high expectations for your personal growth and success as a student in this semester.  If you cannot figure something, I expect you to see me so we can seek a solution to the problem.  I will do my best to ensure that you learn the maximum and that your effort is rewarded with good grades.  I take a great deal of pride on how much my students learn and on the well-earned grades they receive.

Note that this is a three-credit course.  Your total effort per week should average 9 hours.  This will include approximately 3 hours of lecture and at least 6 hours of outside work.

Recording and Duplication of Course Materials: Lecture presentations, lecturer's notes and outlines, handouts, and exam materials are the property of the instructor and may not be recorded or duplicated for commercial use or sale without the permission of the instructor.  Students are permitted to record lectures for individual use only.  Commercial note-taking services are expressly prohibited.

 
 

7. Office Hours

My policy regarding office hours is that if I am in my office or my lab, I am available. I will try not to have scheduled meetings right after class, the most convenient time to talk for all.  If you need to discuss something that requires a lot of time, please make an appointment.

Room Number: LSE 202A

Phone Number: (870) 972-3082

8. Evaluation Criteria

Exams: The course will have four sources of evaluation totaling 500 points broken up as follows:

a)  Two 100-point exams will be given.  They will consist of critical thinking questions about the material covered in the lectures.  These exams will be take-home exam.  The final exam is not accumulative but if you do not know the material previously covered in class you will not do well anyway.                                                     POINTS            200

b) Quizzes. After each class there will be a quiz

     about that class material                                                    POINTS            100

c)  Class presentation of species account                               POINTS            100

d) Participation                                                                         POINTS           100

                                                                                                  TOTAL =         500

Graduate students and Honors Students are expected to write a paper.  That paper has a value of 200 points that will be prorated with the 500 points described above.

No make-up exams or quizzes will be given under any circumstances, not even in cases of tardiness.  If a student misses a scheduled examination s/he will receive a grade of zero.  All deadlines must be met.  No excuses will be accepted.

The grading scale is as follows:

          Points          Grade

          450-500           A

          400-449           B        

          350-359           C

          300-349           D

          Below 300       F

Incomplete grades will be given only in rare cases where the student suffers from some type of physical disability or illness that prevents the completion of the second half (that is after the first exam) of the semester.  Medical documentation will be required.

The guidelines for the research paper are as follows:

After discussing the topic with me, you may have the opportunity to write an original research paper on a particular topic.  Grading will be based on originality, clarity of ideas, and quality of the substance and presentation.  The paper must be type-written and double-spaced and submitted electronically.

The paper must be a review article about a topic in marine mammals, that is, an in‑depth summary and discussion about your topic.  This assignment is in two parts:

           First, a literature search plus a 2‑page summary of two of the articles from the primary literature is due at the beginning of class on January 26, 2009.  You must include the print‑out from the online computer search, your summary of the two articles, plus a copy of the two articles.  This summary must be at least 2 full pages, but not more than 3.  The summary must be typed exactly in the style of a term paper, i.e., the statements that you make in the summary must be supported with appropriate citations that are then listed in the "literature cited" section at the end of the paper.  The two articles must address the same topic and your summary must indicate the relationships between the two papers.  For example, one paper builds on the work of a previous paper, or the two papers present opposite views of the same topic, or the two papers reach the same conclusions but use different methods.  The summary should include why the authors performed the research, how they did the research, what they found, and a discussion of the results.  Also include a paragraph discussing why you chose your particular topic.  This summary is worth 25%.  The summary will be graded upon your ability to summarize the findings and its grammatical correctness.

        The second part is the paper itself, which is worth 75%.  There is no upper limit to the number of citations that would be appropriate.  You should use as many as is possible concerning your  topic, however, minimally the literature cited section must contain at least 10 citations, with at least 7 of these from the primary scientific literature.  Your paper should be typed and double‑spaced and at least six pages of text, exclusive of the literature cited.  PAPERS THAT DO NOT MEET THESE VERY MINIMUM REQUIREMENTS CAN EXPECT NO MORE THAN 70%.  Your paper will be graded on its scientific content and the coverage of the topic, in addition, the paper will be graded on grammar, clarity, and freedom from typographical and spelling errors.  Papers are due on May 1, 2009. 

Plagiarizing your paper from some other source or collaborative efforts with other students will be considered cheating and your behavior will be reported to the appropriate ASU office for punishment that may include expulsion from the university.  In addition, if you turn in essentially this same paper for a different class, I will consider it cheating and you will also be prosecuted for violation of academic integrity.  I will always be available to discuss with you the progress of your research paper at any stage prior being handled to me.  However, you must know that I will measure it to the highest scientific standards.  Any work submitted by an individual student is expected to represent his/her individual, personal work.  Passages of text, images, diagrams, pictures, or original ideas drawn from other sources must be clearly identified, both by separating the passage from the neighboring student‑written narrative (using quotation marks or block indents) and with citations and reference to the original work or individual.  Any student submitting in their name the work of another student, individual, or author is committing plagiarism and will be referred for disciplinary action.  Read the academic integrity section of the Student Handbook. Details of all suspected violations of academic integrity will be reported to the appropriate authorities.

        If you feel I have erred in grading, please let me know, and I will regrade your entire exam.  You might get points back, but then again, I might see something I missed before... 

 
 

9. Letters of Recommendations

Those students that have excelled in my class can always count on strong letters of recommendation upon request.

 
 

10. Attendance

Attendance is expected at all lecture sessions.  Attendance will be taken at the beginning of each class.  I can be flexible if in a very occasional fashion you are late and I will give you an "attended" mark for that day.  However, regular tardiness will not be excused.  Since there is not textbook, students are expected to come to all sessions.  I reserve the right to penalize those who do not attend by not granting favors.  Class attendance is one of the major characteristics that employers are interested in when hiring new employees because it tells a lot about one's commitment to assigned tasks and the ability to deal with varying life situations.  For example, there is an increasing tendency for some students to miss a class in one course in order to study for a test scheduled later in the day.  Although there might be times when such decisions are necessary, studies suggest this is usually not a valid decision.  Not only does it seldom result in a significant increase in the test score, it is considered an indication of lack of confidence and/or poor time management.  The problem is usually magnified when one is later tested without adequate notes (or no notes) from the missed class.  If you must miss class for any reason, you should get notes from two classmates, review the notes, and then see me to clear up any questions about the missed class.  It is best to do this by the next class period since the importance of the missed notes often quickly diminishes with time only to resurface the day before a exam or perhaps during the exam.

 
 

11. Academic Honesty

To ensure the highest standards of academic honesty and ethical behavior, the Honor Code will be strictly enforced.  In other words, do not even think about any behavior that may be construed as academic dishonesty, plagiarism, misrepresentation, or cheating.  Academic dishonesty includes, but is not limited to the following:

A. Cheating on an examination, taking information or allowing information to be taken

     from test.

B. Receiving help from others in work to be submitted, if contrary to the stated rules

     of the course.

C. Plagiarizing, that is, taking and passing off as one's own the ideas, writings or work

     of another, without citing the source.  This is true whether the material used is only

     a brief excerpt or an entire paper or article and whether the original source is the

     work of another student or some publication.

D. Submitting work from another course.

E. Stealing examinations or course material.

F. Falsifying data and/or records.

G. Assisting anyone to do any of the above.

The honor code protects the honest student, the reputation of Arkansas State University, and the value of degrees earned here.  We should all support it both by personal honesty in all things and by refusing to tolerate dishonesty in others.  Any graded work must be performed completely unaided.  Students must report to me any suspected cheating.  If you have any questions about your assignment, plagiarism, or the Honor Code, please contact me.

 
 

12. Withdrawals

You are the sole responsible for fulfilling all necessary steps to formally withdraw from this course.

 
 

13. Students with Special Instructional Needs

If you have any special needs related to learning or testing in this course, please let me know as soon as possible so I can address those needs.

HOW TO SUCCEED IN MY CLASS

Every professor has his/her own values on how to judge students.  This ranges from knowledge to attendance, from attitude to hard work.  Everyone of us is different in his/her methods and approaches, but all of us want our students to succeed by learning and getting good grades.

What follows are a series of recommendations that, if pursued, would put you pretty much on the path to success:

1. Show up.  My lectures contain the information you should know.  Attending class and taking notes will help you focus on what is really important, in what I consider to be essential.  I use a lot of PowerPoint presentations, videos, and transparencies.  I also like to challenge my students, to engage in discussions, to make the class a truly participative experience.  You cannot get this information from another student's notes.  You need to observe my delivery: you need to know not only what was said but also how it was said.  Besides, when you study without having been in class, you are learning the material for the first time.  When you study after you have been to class, you are reviewing.

2. Attendance record.  Make no mistake about it: in the subjective realm of grading, attendance always counts.  I respond positively towards students who come to class regularly.  Repeated absences will lose you the benefit of the doubt when it comes to grading, and you might very well need that benefit.  For this class, learning is accumulative, with each class building on the previous one.  If you fall behind, it becomes increasingly difficult to catch up.

3. Prepare for class.  The schedule included in this syllabus tells you exactly what topics will be covered and I will email you notices on the reading material before hand.  I may give a quiz at the beginning of the class with questions on what was addressed in the previous class.  I may also ask oral questions during the class; your class performance will be evaluated.  Know the scientific vocabulary and terminology and practice critical thinking.

4. Choosing the right seat.  I use a lot of visuals for this class.  Thus, try to seat in the very first rows.  That will allow you to read the transparencies without difficulty, it would let me notice you (leading me to believe that you are involved and conscientious), and will ensure your participation.

5. Take notes.  Unless you have a photographic memory you should take notes, but do not confuse taking notes with stenography.  I try to make you think during the class and you cannot listen, think, and respond if you are busy playing secretary.  Most of the things that are written on the board and/or shown in transparencies tend to be very important.  Many of my past students have told me that they have found that the best way to follow my classes is by tape-recording my lectures and just taking notes on the information written on the board or the transparencies.  Since it is not practical to have 40 tape recorders on my desk while I am lecturing, I strongly suggest that you form study groups where one student per group is responsible for recording and sharing the tape (see "Recording and Duplication of Course Materials policies," above).  Do not hesitate to come to me with questions or concerns about past lecture material.  Try to understand why we know what we know in science.  Establish connections and links between concepts and ideas covered throughout the course.  Know how the information presented is used, and why it is useful in the real world.  Extend and relate your knowledge and understanding into new contexts and situations.

6. Class participation.  I seek, need, and appreciate student involvement in my class.  There is nothing most frustrating for me than to be talking for more than an hour and not to hear questions or comments.  Animated discussions are one of the best rewards I can receive as an instructor.  That makes me fell successful and will improve your chances for better grades.  I know that speaking before a group is a scary experience for many.  Survey after survey, it has been shown that what people fear most (even more than death, accident, or even losing their job) is to speak in public.  Do not think that by participating you are annoying others, that you have nothing to contribute, or that by asking a fundamental question people will judge you negatively.  They will not judge you: they are too busy thinking about their own comments.  However, as much as I encourage participation, there is one and only one question I do not like to hear, and that is: "Do we need to know that?"  Make no mistake about it: you are not paying tuition (and ASU is certainly not paying me) in order to use the class time to engage myself into idle talk and/or irrelevant material.  Everything I say, everything I point out to, is because I feel is important for you to know, and in consequence it can be asked in a test.  I will use the review sessions, however, to point out to those aspects that I consider really relevant for you to prepare for the exam.

7. Form study groups.  My most successful students form study groups.  Talking about the material, quizzing each other, and sharing time exploring the material, builds your interest and comprehension, and makes learning fun.

 
 

Disclaimer:  The information contained in this syllabus is as accurate as possible, but may be subject to change with reasonable advance notice.  The schedule and content of lectures and assignments may be changed at the discretion of the instructor upon oral notification in class.  Changes may involve additions, deletions, substitutions, or changes in sequence or due date.

FAILURE TO FOLLOW THE DIRECTIONS CONTAINED IN THIS SYLLABUS COULD CAUSE YOU TO GET A POOR GRADE IN MARINE MAMMALS

Students' Evaluations (Spring 2005)

1. "He is a good instructor, he explains his material good. But we could use more instructions or better ones-when it comes to assignments."

2. "Dr. Romero is a great teacher, he is genuinely interested in helping students learn. Nothing should be changed about this course. He is also very helpful outside of class."

3. "Dr. Romero is an excellent professor, & it is obvious that he loves to teach. He really knows the subject matter & stands apart from many professors in that he really cares whether his students learn a lot in his class. Tests were fair & laid out well, & he was always more than happy to answer questions both in & out of class. I give him an A+!"

4. "I enjoyed this class- I like how we had exams due electronically-got to experience some things I would have never been able to explore b/4.(w/ a smiley face)"

5. "Interesting, involving, prepared, relevant. Overall a good course."

6. "Marine Mammals has been an exciting and informative class. Dr. Romero is enthusiastic and extremely knowledgeable about the subject he teaches."

7. "The class was very relaxed and enjoyable and I learned quite a bit from it. I like that more emphasis was placed on thinking rather than regurgitation of memorized material. I would definitely recommend this course to anyone with interest in marine mammals or even biology in general."

8. "I really enjoyed this course. This was something that I have always been interested in & I am glad that I had the opportunity to experience it. It has helped me realize that my decision to stay in science was a good one. Dr. Romero is a wonderful instructor who always willing to lend a helping hand & motivate us to do our best, he makes an already interesting topic even more interesting."

 

 
 

Students' Evaluations (Spring 2007)

- This was a great course!!!  I absolutely loved and enjoyed it.  Our teacher was everything a teacher should be!  He was fair, helpful, and made this course interesting—I wish there was a Marine Mammals II he taught!  Very happy!!! With course and teacher!

- Dr. Romero was the most interesting and exciting teacher I have ever had.  I learned more than I hoped to.

 - This class was fantastic.

 - The class was very interesting and it was thought in a way that way attention was captured every class.  Very dynamic and interesting.
