“The human race is challenged more than ever before to demonstrate our mastery, not over nature but over ourselves.”  - Rachel Carson 
 
Introduction
Welcome to a new and exciting academic year!  I am delighted to join you for the next two years as we explore biological topics and their role in the global landscape.  Diploma Program (DP) Biology is a challenging yet rewarding course.  The curriculum promotes inquiry and investigations into systems both large and small, with a focus on practical skills and their applications in solving real-world problems.  While both SL and HL students work to develop the same skills and attitudes, the HL curriculum is one of increased breadth and depth.  All units of study include the core topics, which are common to both HL and SL.  Each unit will also include additional content for HL students.  
 
Course Aims (as described by IB)
  • appreciate scientific study and creativity within a global context through stimulating and challenging opportunities
  • acquire a body of knowledge, methods and techniques that characterize science and technology
  • apply and use a body of knowledge, methods and techniques that characterize science and technology
  • develop an ability to analyse, evaluate and synthesize scientific information
  • develop a critical awareness of the need for, and the value of, effective collaboration and communication during scientific activities
  • develop experimental and investigative scientific skills including the use of current technologies
  • develop and apply 21st century communication skills in the study of science
  • become critically aware, as global citizens, of the ethical implications of using science and technology
  • develop an appreciation of the possibilities and limitations of science and technology
  • develop an understanding of the relationships between scientific disciplines and their influence on other areas of knowledge.

Expectations
What to expect from the instructor:
·      Enthusiasm, passion, and curiosity
·      Listening to students with empathy and concern
·      Subject mastery, but also a willingness to learn new things and practice new skills
·      Timely and constructive feedback
·      Open communication
·      Use of a variety of instructional practices
·      Preparation for the IB exam and the Internal Assessment (IA)
 
What is expected from the student: 
·      Respect the collaborative, open-minded, and creative classroom environment
·      Advocate for your needs and the needs of others
·      Practice self-management and autonomous learning
·      Utilize given resources in order to be prepared for the day’s activities
·      Be present in class- physically, mentally, and emotionally
·      Maintain academic integrity on all assignments
·      Take risks and make mistakes- we grow the most when we are willing to be vulnerable

Course Grades
In addition to the IB score at the end of year 2, students will receive a quarterly course grade on their ISB report card.  The course score of 1-7 will reflect the achievement levels on the following: 
·      Tests.  Students will have exams after each unit that will mimic papers 1 and 2 (and sometimes 3).  Semester exams and other comprehensive exams will also be included in this test category.  Review and revision will be part of the course, but students should also take time and utilize given resources to prepare for tests.  Every effort should be make to take the exam on time.  
·      Quizzes.  Students will have quizzes at least once per week.  These will cover recently-learned content or skills.  Therefore, it is important to come to class prepared and to take individual time to review if necessary.  
·      Lab work.  Over the course of two years, students will complete 6 required labs (practicals). Higher level students are also required to complete an additional 7th lab.  These will be a part of the grade, as will labs in class that are beyond what is required by IB.  Feedback on lab work should be carefully considered in preparation for the IA and for the paper 3 exam. 
 
All of the work that we do is important, but not all of the work that we do becomes part of the course grade.  Many assignments that we will do are geared towards generating thought, identifying misconceptions, organizing information, and providing work suitable for feedback. They will be scored, but they will not become part of the formal grade.  It is expected that students complete these to the best of their ability to help determine the instructional needs of each individual.  This includes: 
·      Notes/Homework
·      Review activities
·      Practice questions and exams
