Using Project EDDIE modules in Oceanography
About this Course
EDDIE Module(s) Adopted and/or Adapted
I implemented the Hypoxia module in a course in Introductory Oceanography. This was an excellent class for an initial implementation of the module because there were only four students (all science or science education majors), who were quite willing and excited to work with authentic data. I adapted some of the material for later parts of the module as there were several weeks in between implementing parts A&B and C&E.
Relationship of EDDIE Module(s) to my Course
Implementation of this module was split based on when content was presented. Modules A&B were done after students learned about basic ocean chemistry. I had them do some exercises from Katryn Wieses's online Oceanography lab manual (https://fog.ccsf.edu/~kwiese/content/Classes/ocan_1l_text.html). I highly recommend having students work trough her Chemosynthesis, Respiration, and Decomposition activity before starting the hypoxia module. Later, toward the end of the semester, students did modules C and E after we covered aspects of life in the oceans.
The module was implemented over the three class periods. Two earlier in the semester and one later. I only made adjustments to module E by providing a series of prompts for the final question (see attachment - "Summary prompts")
Also, because there were several weeks between modules A&B, I provided them with a summary of the key findings derived from the first two modules before they completed modules C and E. (see "Summary A&B")

How did the activity go?
Students benefited from the activity because they were asked to explain their observations in the graphs and postulate what additional information they needed. One student, who had not used Excel struggled with it and I had to guide him through the procedures again. The other three students, who all were familiar with Excel, were not familiar with Excel equations or some of the techniques for graphing multiple curves in one plot.
I found that students had a good understanding of human-caused hypoxia, but they did not seem to get that hypoxia can also be a natural process that has occurred throughout geologic time.
