COURSE OBJECTIVES:

      Welcome to General Botany.  Botany is an excellent way to introduce you to the world of biology.  Although plants are wonderfully complex and diverse in their own right, the cohesiveness of this group provides a great place to begin exploring the functioning of organisms and the fundamental concepts of biology.  In this course, we will examine a wide range of topics related to the biology of plants.  In the first part of the course, we will investigate in detail how the individual plant works:  how plant bodies are built, how plants obtain and transport food and water, and how plants reproduce themselves.  Next, we will discuss the principles of evolution, how evolution has produced the incredible diversity of plants today, and how human activities threaten these important organisms.  We will finish the course by examining the ecology of plants and forests, how these ecological principles apply to environmental problems, and finally the ecology and environmental science of Maine's forests.  Throughout the term, we will reinforce coverage of these fundamental principles with lab and field observations of plants and forests.

 

      The objective of General Botany is not merely for you to acquire information about these topics.  Instead, you will learn general principles that govern physiology, anatomy, heredity, evolution, and ecology, and ways that these principles are applied in biological and environmental science.  Our study of these topics will also enable us to consider the nature and practice of the science of biology:  in other words, how these principles were discovered.  Finally, we will use the course material as a vehicle for developing your skills in conveying knowledge through technical writing and oral presentation, and using the computer as a tool.

 

      I hope that through this course you will develop four categories of understanding:

¥     How plants work: physiology, morphology, anatomy, reproduction

¥     Biology principles: genetics, evolution, ecology, biodiversity, environmental biology

¥     Application of biology to environmental problems: food production and human population growth, acid rain, global warming, the species extinction crisis, Maine forest issues

¥     Process skills in science: doing science, searching the scientific literature, writing about science, speaking about science, using computer technology

 

      I urge you to think of this course as a window to the fascinating world of life and as an opportunity to develop your career skills.  Again, welcome to General Botany.  I'm looking forward to an enjoyable semester with you all!

 

 

ON-LINE GENERAL BOTANY:  USING BLACKBOARD:

      We will use a web-based course management system called Blackboard.  I think that youÕll like Blackboard.  You will be able to download outlines of my lectures and course handouts, submit papers, check the syllabus and calendar for the course, participate in on-line discussions, check your course grade, and check out web links that can help with the course material.  Since it is web-based, you can get into and use Blackboard with any computer with internet access.  You should check Blackboard every day or at least every other day in case I have sent an important message.  Access General Botany on Blackboard at http://www.courses.maine.edu.  You will be guided on what account ID and password to enter to gain access to the General Botany site.

 

Blackboard is fairly straightforward to navigate and use.  When you log in, you will always be greeted by the Announcements page, which will provide you with any important messages for the course.  Click on Syllabus to see the course syllabus, which you are now reading.  The Lecture folder contains outlines for each lecture and exam study guides, and the Lab folder provides handouts and assignments for each lab.  Unless you have a laptop that you will bring to all classes, it is very important for you to print out these items well before you need them.  To do that, simply click on the item, which will open it up in MS Word or an MS Word reader in Internet Explorer; then print.  The Student Tools section has the following very useful tools for the course: Digital Dropbox for submitting papers and getting back my comments; Check Grade for checking your current score in the course (in comparison to the entire class if you would like); Calendar for checking on important dates in the course; Tasks for you to keep a list of tasks for yourself for the course; Groups for communicating with a group of students in the course.

 

Here are few tips for navigating Blackboard:

 

1.         Although I prefer Netscape Navigator, itÕs better to use Internet Explorer for Blackboard.

 

2.         Once you are in Blackboard, try to avoid using any of the navigation buttons at the top of Internet Explorer (e.g., ÒBack,ÓForward,Ó Reload,Ó etc.).

 

3.         When you hand in a paper via Blackboard, use the ÒsubmitÓ button not the ÒAddÓ button.

 

      Important reminder for all of your courses: always, always back up your computer work on two diskettes or zip disks!!!

 


EXAMS, ASSIGNMENTS, AND THE GRADING SYSTEM:

      Your grade in this course will be based on your total percentage for lecture and lab combined -- out of a total of 890 points.  More than 50% of these points will be from lecture and less than 50% are from lab.  The average percentage performance for students in this course over the last three years has been about 76-77 %.  (Last year, it was 77 1/2 %.)  Although the distribution changes some year to year, it is typically within the following range: A: about 10%, B: 25-35%, C: 30-45%, D: 10-15%, F: 5-10%.

 

      Lecture Hourly Exams (three during the regular semester and one during the Final Exam period) will be a combination of multiple choice, quantitative problems, and essay.  Lecture exams will emphasize lecture material, but also will include material from the required reading.  You will be reading sections from both a botany textbook and from a complementary book of essays about a forest near Weld, ME, about 20 miles from here.  In lecture, you will keep a brief Journal (in a "blue book").   At the end of lectures or at other times, you should write down a few thoughts about the course: ideas that are not clear, notes regarding what you need to work on, and other appropriate comments.  Journals will be collected at four random times over the semester.  I will use the journals to record your lecture attendance and to assess and redirect the course.  Your journal notes will not be graded; you will receive full credit for simply handing in the journal when solicited.  You will also be given four Quizzes during the term, one in the middle of each of the four sections of the course.  These quizzes will encourage you to attend lecture and to review the material more often than before each exam.  If you simply read over the lecture notes covering the material since the previous exam, you will do fine on the quizzes.

 

      Lab assignments are quite varied.  You will hand in a Worksheet at the end of each of four labs.  In Lab 3, you will take a Field Practical assessing your knowledge in identifying tree species.  The Lab Practical will be a combination of written and practical (hands-on) questions.  You will collaborate with other students in giving a Plant Adaptation Presentation on adaptations of plants to a particular environment.  Late in the term, you will write a Technical Paper (i. e., lab report) based on an experiment on "fast plants" that will take place over most of the semester.  You will hand in a partial First Draft for this paper for which I will provide help.  Additional information will be provided on the lab exam and assignments as the term proceeds.  Note that 20 points are allocated to participation in lab (participating in discussions, collaborating well with partners, working diligently, etc.).

LECTURE GUIDELINES:

            The schedule of lectures is given below. Lectures will vary greatly.  In some, I will lecture the entire time, soliciting little input from the class.  Other lectures will emphasize group work and class participation.  Come prepared for answering questions, being called on, and actively participating in lectures.  In all lectures, I welcome your questions and comments.

 

            Note that outlines of all lectures will be available on Blackboard.  I will usually stay several lectures ahead on Blackboard.  These outlines will be of great help to you since they provide a logical framework for the content of each lecture.  You will find that exams will emphasize the material presented in lecture, although some additional content from your reading will also be included.

 

            If you have a laptop that you will use in lecture, simply download the lecture outlines to your computer and bring it to lecture.  Otherwise, you should print out the lecture outline and bring it to class.  Good performance on exams will require that you add your own notes to these outlines in order to clarify and elaborate on the outline.  You will notice that some of the outlines are quite comprehensive, including almost all of what I cover in lecture, whereas others are much more skeletal, requiring extensive note taking on your part.  Again, it will be very important for you to take additional notes during most of my lectures.  Reading over the lecture outline before the lecture will also help you immensely, as would skimming back through it after lecture.

 

            Lecture outlines will provide a reminder of the reading for the current and the next lectures and sometimes other reminders.  Two other very important points.  First, in the lecture outline, terms that are underlined are especially important; learn them well.  Second, you should be able to answer questions in the outline that are in italics.  Read over the lecture notes before lecture and be prepared to answer these questions during my lecture because I might call on you.

 

 

LABORATORY GUIDELINES:

      The schedule of labs is given below.  You must print out a copy of the lab handout from Blackboard and bring it to lab.  It is imperative that you read the lab handout or assigned pages in your textbook before lab.  For labs where it is indicated (see lab schedule below), bring your textbook to lab.  Note that you will often hand in completed work sheets at the end of lab.  On these worksheets, complete the parts indicated in lab and label all drawings clearly and completely.

 

You will need to move through lab exercises expeditiously, but don't be in a hurry to get out.  Lab does not end until 4:50; expect to stay at least that long.  If you leave before 4:15, you probably have not completed your work satisfactorily.  Be sure to clean up after yourself  before you leave lab.  There is a trash can for recyclables, a can for other trash, and a box (the "Sharp's box") near the sink for broken glass.  Cover slips can be thrown in the Sharp's box, but wash, dry, and return blank slides.  Return microscopes to the cabinets carefully.

 

      Dress appropriately for field trips!!!  Be prepared for somewhat dirty, maybe wet, possibly cold, but definitely exhilarating conditions on the field trips.  We will venture out under all but hurricane conditions.  Wear good mud shoes, warm clothes, waterproof gear, and snow shoes (just kidding) where appropriate.  Bring a notebook and pen or pencil.

 

 

ATTENDANCE AND PUNCTUALITY:

      Attendance in the course is mandatory.  An unexcused missed laboratory will result in an automatic 30 point decrease in total lab points.  DonÕt miss a lab!  An unexcused missed exam will result in a zero grade.  Permission for missing an exam or a lab (or moving to another lab for the week) is possible  only if you contact me before your lab or exam.  If you have an emergency, contact me as soon as possible.  Reasonable excuses for a missed lab or exam are the following: death in the family, serious illness (a cold is not a serious illness), and a serious personal problem.  Do not schedule other appointments of any kind during the meeting times for the course; such conflicts will usually not be considered a reasonable excuse.

 

The assignment schedule is provided on this syllabus and on Blackboard, so extensions on due dates should not be necessary.  Reasonable excuses for extensions are the same as for missed labs and exams.  For assignments handed in late with no excuse, 10% of the possible grade will be deducted from your grade for that assignment for each day beyond the due date.

 

Let me emphasize this:  contact me as soon as possible when problems arise, and we can deal with it; if you don't contact me, I will have to count it as an unexcused absence or late assignment. 

 

 

SUCCESS AND PROBLEMS:

      The course material for General Botany is sophisticated and the pace of the course is challenging.  You will likely find the course a big step up from high school biology courses, even if some of the material is similar.  Let me assure you, however, that you can do well, and I want you to do well.  This course is not designed to "weed out" students.

 

      What does it take to perform well in the course?  Some suggestions:

á            attend every lecture and lab,

á            during lecture, take notes in addition to the outline provided,

á            review your notes periodically to assess your understanding (and clear up any problems),

á            stay "on top" of the assignments and required reading,

á            work with other students on clarifying the problem areas,

á            begin studying at least five days prior to an exam,

á            if youÕre having problems, get help.

 

Remember: I am here to help you and will be available in office hours, by phone, and by email.  If youÕre having problems, we will discuss the possibility of your getting help from a free General Botany tutor (at the Learning Assistance Center in Merrill Hall).  Also, try the textbook web page (http://www.brookscole.com/biology/member/student/plant_bio/index.html), which has lots of flashcards, practice tests, links, etc.  Let me reiterate: if major problems arise (lost in the course material, illness, personal problems, etc.), don't put off talking to me about it.  I can help much more one week before an exam or assignment than one week after a due date.

 

Academic honesty is expected of all students in this course.  Plagiarism, cheating, and other departures from academic honesty will, of course, be dealt with harshly in accordance with UMF rules.

 

 

Equal educational opportunity is offered to students with special needs due to disability.  Please notify the instructor if a reasonable accommodation is needed to meet course requirements.
