  26. Overview of Lesson • Why are we here? • Goals of the course • Syllabus and grading system • Scientific methodology and publication

  27. You will want to put your own syllabus here

  28. Readings for Lessons and Labs • From popular press (Time Magazine, U.S. News & World Report, Newsweek) or health-related web sites • At the start of each lesson, there will be a lesson quiz on the day’s reading and the previous lesson

  29. Example: Daily Quiz Question • Which of the following statements is most FALSE? • A. Infection with HIV causes an increase in helper T cells, leading to death. • B. HIV is transmitted by both homosexual and heterosexual activity. • C. Currently, there are no drugs that totally eliminate HIV from the body. • HIV has killed more people in Africa than any other continent. • If none of the above statements are false, select E.

  30. Labs and Activities Wet labs and computer activities are used to enhance lessons A quiz will be given at the end of each lab or activity Material covered in labs and activities will be included on exams

  31. Overview of Lesson • Why are we here? • Goals of the course • Syllabus and grading system • Scientific methodologies and publication

  32. Advances in Biological Knowledge Immunology Anatomy Molecular Biology and Genetics Knowledge Ecology Evolution The unknown is greater than the known Year 1950

  33. Advances in Biological Knowledge Molecular Biology and Genetics Immunology Anatomy Knowledge The unknown Is still greater than the known Ecology Evolution Today

  34. Scientific Methodologies Observation Hypotheses Tests of hypotheses Results

  35. Two-group experimental design Identity the variable which will test the hypothesis CONTROL GROUP EXPERIMENTAL GROUP The variable being tested The variable being tested is absent is present Record results Record results Compare and analyze the test results Report on experimental design, test results, and conclusions drawn from results Based on: C. Starr’s Biology: Concepts and Applications, Brooks/Cole, Thomson Learning

  36. Science advances by disproofPlatt, J. (1964) Science

  37. Scientific Methodologies Observation Hypotheses Tests of hypotheses Results World knowledge in scientific journals Publication Rejection Peer review Submission of paper to scientific journal

  38. Results become a part of the general knowledge only after they are published in a scientific journal

  39. Question: Why can you have confidence in the popular press and professional web sites? Answer: Because the information is based on scientific methodology and scientific journals, not pseudo-science

  40. Scientific Methodologies Reputable Popular Press Observation Hypotheses Tests of hypotheses Results World knowledge in scientific journals Publication Rejection Peer review Submission of paper to scientific journal

  41. Beware of pseudo-science (a system of ideas or misconceptions erroneously regarded as science)

  42. Based on: The Sun, January, 1993

  43. Based on: Texas Highways, May 1999

  44. Next Lesson Menopause and Hormone Replacement Therapy
