This first week of the environmental health unit is based in a more traditional approach of education where I deliver knowledge to the class. I begin in this fashion to ensure an equitable access to what I consider the important background knowledge for the unit. I base the beginning of each of my units within content provided by the World Health Organisation.
Initially I use the World Health Organisation to define Environmental Health. Their page titled Environmental Health explains the generic definition, then I move the the section titled Public Health and the Environment to further inform that definition. At this point I discussed the two interpretations of the terms environmental health;
- the health of the environment
- the impact of the environment on human health
I stress (and re-stress) that it is the second interpretation we are concerned with in this unit of study. Once that is established I take the class through the WHO Environmental Health Fact File, which is a list of (somewhat repetitive) facts on environmental health. This tends to open the students eyes to the problems of the world. If there is time, I also ask them to read one of the articles posted on the website. A written response to this is a possible outcome. The article I tend to choose is entitled The Environment: where’s the risk, and where are the children safe?
I then introduce a list of six basic environmental health needs. I have lost where I resourced this list from, but it is still useful today. The six basic environmental health need are;
- clean air
- clean water
- dependable food supply
- hospitable habitat
- uncontaminated living environments
- uncontaminated working environments
Later in the course we look at disruption of these needs as an environmental health risk.
Up to this point, I have been talking global health to them. As our investigation will be focused on our school, I use WHO’s definitions of settings to begin to develop in the students the ability to define a micro-environment. Within this section you can navigate to a specific article on school settings, however I tend to focus more on the general definition as it serves my purpose better. We use the general definition to determine if the school can be considered a setting or not (and of course it can).
At this point, I turn to Wikipedia, and its list of Environmental Health Concerns. This forms a basis for discussion, where we discuss if the listed concerns are applicable to our school setting. At this point I’m not looking for a discussion on significance or solutions, simply an acknowledgement on whether the concern could be present in our school setting.
From this point, students will be paired and sent to gather evidence on a chosen environmental health concern. Presentation and discussion of this evidence to the class will result in decisions on significance of the issue or not. I hope that by doing this gathering of evidence, groups will not choose irrelevant foci for their investigations later this term.
