ADVANCED PLACEMENT BIOLOGY SYLLABUS (2011-2012) Mr. Mark Stephansky Room: 202; Office: 205E E-mail: mark.stephansky@whrsd.org School Phone: (781) 618-7441 Office Hours: Before school, after school, and during seminar Course Web Site: http://www.whrsd.org/stephansky COURSE DESCRIPTION: This course follows the guidelines created by the College Board. It is designed to be equivalent to a college level introductory course. Successful completion of the AP Biology exam can lead to either introductory biology credit or elective credit depending on the requirements of the college a student is attending. COURSE OBJECTIVE: AP biology students will demonstrate the ability to use specific skills and processes, appropriate scientific terminology, and major biological concepts to explain the uniqueness and interdependence of living organisms, their interactions with the environment, and the continuation of life on Earth. TEXTBOOKS: Campbell, N. A. and Reece, J. B., Biology, Edition 7, Benjamin Cummings Publishers (2005) ISBN RECOMMENDED PURCHASE: Pack, P. E. Biology AP Test Preparation, Cliff’s Notes, 3rd Edition (2007) You will each have a textbook checked out to you. You are responsible for your own book’s care. In addition to the text, supplemental reading materials will be given periodically. SUPPLIES: Large 3 ring notebook w/dividers for Notes, Guided Readings, and Labs; scientific calculator. LOGISTICS: This class meets for one period every day for the entire school year. Class periods will be composed of lecture, labs, quizzes, and exams. A premium will be put on both labs and essay composition. Each exam will have at least one detailed essay, and many quizzes will be in-class or take-home essays. I expect all of those who enroll in AP Biology to prepare for and take the Advanced Placement Biology exam. This class has a very special dynamic when we are all working towards the same goal. If you are not looking for an academic challenge at the highest level, you should consider taking a different course. 1 of 11 (Adapted from Wartski, Sharp & Fazio) ASSESSMENT AND EVALUATION 20% Homework and Classwork Assignments 25% Laboratory assignments and reports 20% Quizzes and Essays 35% Tests Individual assignments include “Reading Guides” from the Campbell text along with supplemental readings and essays. Students will be required to turn in “Reading Guides” on a regular basis; this will insure they are keeping up with required reading. Other reading assignments and essays will be assigned periodically throughout the year. Part of the college board requirements for AP Biology is a series of 12 labs; students will complete these labs along with the worksheets/ lab reports that will be assigned along with them. In addition to the required 12, other labs and laboratory-based activities will also be assigned. Quizzes will be given periodically to assess learning. Exams will follow after every unit and at the semester. Grading, Grades, Cheating, Exams, Homework.... This year in my class, I will be practicing a form of Mastery Teaching. In Mastery Teaching, students are allowed to master the content at their own pace. Students are allowed to hand in lab reports, projects, and other assignments after the due date. However, for each day an assignment is late, twenty percent of the total points will be deducted from the grade earned. After five school days, or one school week, the late assignment will no longer be accepted and recorded as a zero. If a student earns a grade on an assignment that s/he feels is unsatisfactory, the student has the option of fixing the assignment on a separate sheet of paper and stapling the correction to the old assignment, and handing the assignment in for possible full credit. The student will always receive the higher grade. The deadline for re-doing an assignment is the deadline for late assignments, or one school week after the original due date. I do make some exceptions, however. If a student earns a 90% on an assignment, s/he cannot re-do the assignment for a higher grade. I do not allow corrections on textbook guided reading assignments, extra credit assignments, and quizzes (other assignments might be added during the year). If a student earns a 50% or greater on an exam, then that exam may be corrected. The exam must be corrected within a brief window of time (usually for 4 days following the original exam). It will be the responsibility of the student to make assignment corrections. I will not remind any student when her/his impending corrections are due. This policy is a privilege, not a right. The purpose of making exam corrections is for you to relearn the material that you have not mastered yet. Short-cutting this process defeats the purpose of this policy. Violations will result in a loss of the privilege. (See also below) Up to date grades will be posted on Infinite Campus. Students are responsible for checking his/her grade for accuracy. I am not perfect, and I have been known to make mistakes. If a student finds a mistake in her/his grade, s/he is expected to see me in a civil manner and point out my mistake. I will correct the mistake and the correction will be posted. With my Mastery Teaching, I am angered and frustrated when students attempt to cheat. If a student cheats, s/he will be caught. If students copy each other, everyone involved will receive a zero. If I feel that the assignments are copied, all parties will have to civilly defend themselves. I hope that I will not have to deal with cheaters. However, if cheating seems to be the norm, I will rescind my Mastery Teaching policy. (I also consider the following cheating: students using notes, exams, quizzes and laboratories of students who have taken my class in prior years. Do not ask an old student to ‘borrow their old Biology material). There will be a time when students are allowed to use a ‘'legal cheatsheet.’ When exams are announced, students can write on both sides of a 3-inch by 5-inch index card. There can be no typing, taping, gluing, stapling, or adhering of anything on the card. Students are expected to complete his/her own card. Sharing or selling of the Exam Card is not allowed and will be treated as an attempt to cheat. Students who cheat on an exam will receive a zero on the exam with no chance of retaking the exam. Due dates, for assignments, are recorded on the classroom calendar, which is located on the class web site and at the front of the room. Students need to make sure that their calendar matches my calendar. Nothing is ever written in stone, and assignments are moved from time to time. I try to keep my website up to date, however, the best source of due dates is the classroom calendar. 2 of 11 (Adapted from Wartski, Sharp & Fazio) Homework and other work to be graded must be placed into my “yellow-folder” (3-ring binder). Work to be passed in should never be placed on the front desk. It is the responsibility of the student to hand in the homework before the tardy bell sounds. If a student needs help, I will be available and happy to help before and after school as well as during the seminar period. It is my dream that every student in all of my classes earn an A. In my class, student motivation is the only limiting factor in student success. If you have any questions please feel free to call me at Whitman-Hanson Regional High School (781-618-7441), email me (mark.stephansky@whrsd.org), or visit me in the science office Rm 205E. For notes, book reading assignments, and due dates, please visit my website: http://www.whrsd.org/stephansky ACADEMIC AND BEHAVIORAL EXPECTATIONS: AP Biology provides students with an experience equivalent to a college level biology course. There are extensive reading assignments that the student must complete in order to be successful. Supplementary readings in the form of journal articles, and supplementary texts are also required. In addition students are expected to complete assigned laboratory activities and any other supplementary assignments given throughout the course. At all times students are expected to follow classroom and school rules, behave in a responsible and mature manner, and conduct themselves with honor and integrity. Students are expected to do their own work. Plagiarism and cheating will not be tolerated. (Please also see above) ATTENDANCE AND CLASS PARTICIPATION: This class will move at a very fast pace, and between labs, lectures and reviews, there is really no way to make up a missed class or most of the labs. It is, therefore, essential you attend every class and lab and be prepared to participate. PROVISIONS FOR EXTRA HELP AND MAKEUP: Students who are absent from class are responsible to pick up make-up work or stay after school or during seminar to finish missed assignments. Students should schedule make-up work immediately upon their return from an absence. It also may be helpful to form a student study group. Students should find a group of friends in class and exchange phone numbers and or email. This way on the occasion they miss a class they can contact them and find out what was missed in class that day. STUDY SUGGESTIONS: Focus in class – paying attention in class can save you hours of studying outside of class. This is a college level course and the class will be handled as such, you will be graded primarily on tests and labs and you will be expected to monitor and analyze your own learning. Biology is different from other introductory courses in terms of the amount of vocabulary involved to get a basic understanding of the science. You must study some every day. Waiting to review your notes until just before the exam is a bad idea. Staying on top of the material will help you develop a deeper understanding and keep the material from seeming overwhelming and confusing. There are Guided Reading and Must Know Sheets, tutorial activities (online and on your CD) for each topic – these are both highly useful; be sure you make use of them and bring any questions you have to class. Make use of ALL online resources, especially the Campbell Biology Ed.7 site/CD Come in for help or get help from a classmate as soon as you have trouble with a concept. You need to be an advocate for your own learning. Consider forming a study group, even if it’s only with one other person. Keep an organized lab notebook and organized notes. Your syllabus is your best friend in this class – check it frequently and use it to plan your studying – you always have homework in AP Bio, if nothing else, start reading ahead. After a quiz or test take time to figure out why you missed questions – think about whether you misread the question or needed to study more. If you needed to study more, do it right away – the concepts build on each other AND you will MORE THAN LIKELY be having comprehensive exams at the end of each trimester. And, of course, remember you are always working toward your AP exam on Monday, May 14, 2012. Make sure you do your labs carefully and completely and that you understand what you’re doing and why you’re doing it. Labs are an important part of your preparation for the AP exam, especially for the essay questions. Make up labs immediately – biology lab materials usually have a short shelf life – you can’t do a lab if the organisms are no longer fresh, no longer alive, or are no longer in the right stage of their life. 3 of 11 (Adapted from Wartski, Sharp & Fazio) MAJOR THEMES IN THE COURSE: The AP Biology Development Committee has identified eight major themes that recur throughout the course: I. Science as a Process – Science is a way of knowing. It can involve a discovery process using inductive reasoning, or it can be a process of hypothesis testing. Example: The theory of evolution was developed based on observation and experimentation. II. Evolution – Evolution is the biological change of organisms that occurs over time and is driven by the process of natural selection. Evolution accounts for the diversity of life on Earth. Example: Widespread use of antibiotics has selected for antibiotic resistance in disease-causing bacteria. III. Energy Transfer – Energy is the capacity to do work. All living organisms are active (living) because of their abilities to link energy reactions to the biochemical reactions that take place within their cells. Example: The energy of sunlight, along with carbon dioxide and water, allows plant cells to make organic materials, synthesize chemical energy molecules, and ultimately release oxygen to the environment. IV. Continuity and Change – All species tend to maintain themselves from generation to generation using the same genetic code. However, there are genetic mechanisms that lead to change over time, or evolution. Example: Mitosis consistently replicates cells in an organism; meiosis (and hence sexual reproduction: results in genetic variability. V. Relationship of Structure to Function – The structural levels from molecules to organisms ensure successful functioning in all living organisms and living systems. Example: Aerodynamics of a bird’s wing permits flight. VI. Regulation – Everything from cells to organisms to ecosystems is in a state of dynamic balance that must be controlled by positive or negative feedback mechanisms. Example: Body temperature is regulated by the brain via feedback mechanisms. VII. Interdependence in Nature – Living organisms rarely exist alone in nature. Example: Microscopic organisms can live in a symbiotic relationship in the intestinal tract of another organism; the host provides shelter and nutrients, and the microorganisms digest the food. VIII. Science, Technology, and Society – Scientific research often leads to technological advances that can have positive and/or negative impacts upon society as a whole. Example: Biotechnology has allowed the development of genetically modified plants. 4 of 11 (Adapted from Wartski, Sharp & Fazio) AP Biology Course Schedule 2011-2012 Mark Stephansky • Whitman-Hanson Regional High School Text: Campbell & Reece.
