Backwards Design
editCourse Objectives
- Primary Objectives- By the next class period students will be able to:
- Understand how parasites are distributed in host populations
- Understand how parasite distribution affects the transmission of parasites in time and space
- Understand how to use the knowledge of parasite distribution to fight infectious disease in developing countries
- Sub Objectives- The objectives will require that students be able to:
- Understand the factors affecting the production of infective stages
- Understand the factors affecting the transmission of infective stages to hosts
- Difficulties- Students may have difficulty:
- Understanding the concept of mathematical distributions
- Real-World Contexts- There are many ways that students can use this material in the real-world, such as:
- The control of infectious disease
- The use of parasites as bio indicators

Pre-Lesson Quiz
edit- Define symbiosis
- Give examples of different types of symbiosis.
- What is fitness?
- How can a parasite affect the fitness of a host?
- What do parasites use their hosts for?
- If there is no immune response, how would the number of parasites be related to host age?
- Which hosts are most important to the transmission of parasites?
- How does temperature affect metabolism?
- How do you think temperature would affect parasites?
- How do you think temperature would affect hosts?
Test Your Mettle Quiz
edit- Given that all environmental factors and the target host density is constant, what is the most important determinant of parasite transmission?
- Name at least three mechanisms in which temperature affects parasite transmission.
- Give a definition of a complex life cycle.
- Give an example of a parasite with a complex life cycle.
- What defines an aggregated distribution?
- Which factors cause an aggregated distribution?
- How can knowledge about parasite distributions be used in the control of infectious disease?
- How may global climate change affect the transmission of infectious disease in the tropics?
- How may global climate change affect the transmission of infectious disease in the temperate zone?
