Course Description

Science of Biology is our freshman-level `entry' course in the life science core curriculum. This `entry' status reflects our desire for you to use this course as a gateway to all of your subsequent learning in biology at BYU. Two key elements will unify your introductory study of biology, both of which were first published in the year 1859. The first is the discovery that all living things are made of cells (which of course seems very obvious to us today, but has deep implications for modern biological discovery)--we call this The Cell Theory. The second is the great discovery that all living things share common ancestry--The Theory of Evolution. Without an understanding of evolution, the biological sciences would exist as a set of isolated, specialized fields. Indeed, Theodosius Dobzhansky was right when he said that "nothing in biology makes sense except in the light of evolution." More recently, the National Academy of Sciences has stated that evolution is "the most important concept in modern biology, a concept essential to understanding key aspects of living things" (1998). Why focus on these two ideas as an introduction to biology, and in what ways are these theories unifying concepts in biology? The purpose of this class is to help you answer these questions, and in so doing provide you with an intellectual foundation upon which you can build your own set of advanced skills and knowledge in the biological sciences.

Classroom Procedures

This course is scheduled to meet on M, W and F. During a normal week Monday and Wednesday we will cover each topic with a combination of activities, lecture and class discussion. Practice test questions will be presented during Friday recitation periods. Attendance of Friday class periods are not optional and will be a time for additional discussion, questions and review activities to be conducted primarily by the teaching assistants. The Course Schedule outlines the topics to be covered during each lecture/class discussion period.

Hopes and Expectations

He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully (2 Corinthians 9:6). Biology is a vast discipline. It is impossible in a single semester to cover this field in its entirety. Hence, the selection of topics covered in class--although broad--must be extremely limited. I have selected for you material that I believe will provide you with a strong knowledge base to excel in subsequent courses in a range of biology majors. In addition, this course will not focus solely on content. I have no desire for you to obtain an encyclopedic knowledge of the field by spending all of your time on memorization (although you do need to become fluent in the language of biology). Instead, I am most concerned that you acquire and improve your skills in critical thinking and problem solving. In short, I want you to come away from this class better able to think like a scientist. For some, thinking like a scientist will be a new task. The undergraduate experience is filled with opportunities to sit passively in your

seat without engaging your professor or your fellow students. Initially, some people feel uneasy and inadequate in voicing their ideas, especially when called upon to comment in front of other members of the class. I know of no magic remedy to remove this discomfort, except to practice. It is critical that when you leave BYU that you have mastered the skill of critical evaluation and that you have the tools to test competing ideas. This is what it means to "study it out in your mind.

Course Learning Outcomes

· Understand and be able to use the scientific method: 1. Think critically about the purposes and objectives of scientific studies and data. 2. Become observant of and curious about patterns and processes in living things. 3. Ask essential, specific, answerable questions about observations. 4. Form hypotheses about biological patterns and processes that are testable. · Understand well the following foundational concepts: 1. Cell theory and biological compartments 2. Chemistry of life (biochemical unity, central dogma) 3. Bioenergetics (biotransformation of energy) 4. Reproduction (fission, mitosis, meiosis, etc.) 5. Evolutionary theory

Homework Assignments 300 points 22% 3 Midterm Exams Final Exam 300 points 11% 200 points 33%

Total points possible

900 points


The highest cumulative score will be scaled to 100% and all other scores adjusted accordingly. Thus, if the highest point total in the class was 800 (out of 900) points, a student with a point total of 600 points would be assigned an adjusted percentage of 75% (adjusted up from 66.7%). I reserve the right to grade "on the curve", but this will only be done if it benefits the students in the class. For example, if a student has an average of 80%, that student is guaranteed at least a B- in the class. However, if the distribution of the scores warrants a downward adjustment of the grading scale, the same student may get a B or B+.

To evaluate how well you have achieved the course learning objectives, there will be four exams. The first three exams are not comprehensive. The final exam is comprehensive. These tests may include several ways of assessing subject mastery and critical thinking skills including: definitions, multiple choice, matching, short answer, problems, and short essay. Your TAs will offer review sessions prior to each exam and can help you get a feel for how the exams are structured. Keys to success on exams include completing all of your reading assignments prior to class discussions, thinking carefully and critically about what you have read, completing homework assignments, engaging your peers in discussion about different concepts, attending tutorials, and practicing

problems and questions presented during recitation hours and in your text. Also, don't be shy about coming to see me during office hours! All exams will be administered in the Testing Center. All exams may include several ways of assessing subject mastery and critical thinking skills including: definitions, multiple choice, matching, short answer, problems, and short essay. Bring a calculator. It is your responsibility to know the Testing Center hours and to allot sufficient time to complete the exam. If you show up at the Testing Center on the last day that the exam is offered, and find it closed, too bad. You should allot at least 2 hours for the exam. Exam scores will not be adjusted for improper erasures on the scantron sheets. Any one caught cheating on an exam will automatically fail the course and a permanent note will be placed in your university student record. Late exams will not be given except under very serious circumstances, and only with prior notification.

Life Sciences Learning Center

Help is available on a drop-in basis for PD Bio 120 students in the Life Sciences Learning Center located in 436 WIDB. Hours of operation are M-F 9:00 AM ­ 7:00 PM.

Homework Assignments

The purpose of the homework assignments is to help you practice expressing your thoughts (in oral, graphical, and written formats) on scientific topics and demonstrate an understanding of basic biological concepts in a non-assessment environment. Homework assignments will be distributed in class on the days listed in the Course Schedule. No late assignments will be accepted unless arrangements have been made previous to the due date.

Reading Quizzes

As the text is an important resource, you will be assigned reading quizzes on MasteringBiology due before each lecture at 10 am. The reading quizzes are open book and open note, but not open neighbor. It is your responsibility to take the reading quizzes. Quizzes will not be reset regardless of excuse. If you procrastinate and your computer has a meltdown, you will get a zero on the quiz. If your internet stops working mid-quiz, your quiz will not be reset. As such you recognize that using wireless internet to take your quizzes is done at your own risk. The reading quizzes should help you get into the practice of using your book before each class period to get a basic understanding of the concepts to be discussed in lecture. It is also recommended to use the text after each class period as well to provide more detailed understanding of topics discussed in class.

University Policies

BYU Honor Code In keeping with the principles of the BYU Honor Code, students are expected to be honest in all of their academic work. Academic honesty means, most fundamentally, that any work you present as your own must in fact be your own work and not that of another. Violations of this principle may result in a failing grade in the course and additional disciplinary action by the university. Students are also expected to adhere to the Dress and Grooming Standards. Adherence demonstrates respect for yourself and others and ensures an effective learning and working environment. It is the university's expectation, and my own expectation in class, that each student will abide by all Honor Code standards. Please call the Honor Code Office at 422-2847 if you have questions about those standards. Preventing Sexual Discrimination and Harassment Title IX of the Education Amendments of 1972 prohibits sex discrimination against any participant in an educational program or activity that receives federal funds. The act is intended to eliminate sex discrimination in education. Title IX covers discrimination in programs, admissions, activities, and student-to-student sexual harassment. BYU's policy against sexual harassment extends not only to employees of the university, but to students as well. If you encounter unlawful sexual harassment or gender-based discrimination, please talk to your professor; contact the Equal Employment Office at 422-5895 or 367-5689 (24-hours); or contact the Honor Code Office at 422-2847. Students with Disabilities Brigham Young University is committed to providing a working and learning atmosphere that reasonably accommodates qualified persons with disabilities. If you have any disability which may impair your ability to complete this course successfully, please contact the Services for Students with Disabilities Office (422-2767). Reasonable academic accommodations are reviewed for all students who have qualified, documented disabilities. Services are coordinated with the student and instructor by the SSD Office. If you need assistance or if you feel you have been unlawfully discriminated against on the basis of disability, you may seek resolution through established grievance policy and procedures by contacting the Equal Employment Office at 422-5895, D-285 ASB. Academic Honesty Policy The first injunction of the BYU Honor Code is the call to be honest. Students come to the university not only to improve their minds, gain knowledge, and develop skills that will assist them in their life's work, but also to build character. President David O. McKay taught that 'character is the highest aim of education' (The Aims of a BYU Education, p. 6). It is the purpose of the BYU Academic Honesty Policy to assist in fulfilling that aim. BYU students should seek to be totally honest in their dealings with others. They should complete their own work and be evaluated based upon that work. They should avoid academic dishonesty and misconduct in all its forms, including but not limited to plagiarism, fabrication or falsification, cheating, and other academic misconduct.
