Study Design for Air Quality Research
Study design components.
Students take an in-depth look at what goes into planning a research project, which prepares them to take the lead on their own projects. Examining a case study, students first practice planning a research project that compares traditional cook stoves to improved cook stoves for use in other parts of the world. Then they compare their plans to one used in the real-world by professional researchers, gaining perspective and details on the thought and planning that goes into good research work. Then students are provided with example materials, a blank template and support to take them from brainstorming to completing a detailed research plan for their own air quality research projects. Conducting students’ AQ-IQ research studies requires additional time and equipment beyond this planning activity. Then after the data is collected and analyzed, teams interpret the data and present summary research posters by conducting the next associated activity. Numerous student handouts and a PowerPoint® presentation are provided.
Whether trying to answer research questions or evaluate new technologies, engineers must carefully plan studies that will result in data they can use. This process includes careful considerations of what variables they are interested in and how they can isolate these variables. Having useable data is dependent upon study design and is necessary in order for engineers to move forward with developing or improving technologies or making decisions that impact human or environmental health. Additionally, engineers and other researchers must consider other aspects of the issues they are studying, including technological, economic and social aspects. This activity provides students the opportunity to develop these skills.
After this activity, students should be able to:
- Construct a hypothesis (or research question) that includes a prediction with clearly identifiable independent and dependent variables and an explanation for the prediction.
- Design a study that facilitates the evaluation of a new or replacement technology.
- Complete a project plan, including a materials list, procedure, timeline and data analysis plan.
