Both field and model experiences improved learning about estuaries, with no significant difference between them when comparing raw scores.
Students with “high water activity” demographics scored higher than students with “low water activity” (p < 0.01).
Field experience improves responses to field related questions for “low water activity” students (p <0.05).
Knowledge of Scientific Process
Fun & excitement about Scientific Discoveries
Public Interest in Research
Created a 3-day curriculum for teaching general estuarine circulation consisting of an introductory class, a day in the field or working with a model, and a wrap-up class.
Used the curriculum with two separate classes: one used a model visualization, Virtual Puget Sound (VPS), and one went into the field for direct observation. The introductory and wrap-up material was identical for both classes.
Evaluated all students with pre- and post-tests (true/false); collected specific demographic data also.
Evaluated students using concept maps.
Compared results in three different categories: model, field, and classroom associated questions.

Comparing Learning Between a Modeling Exercise and Field Work on Puget Sound
Puget Sound is a complicated estuary and an excellent place to learn oceanography. In a partnership program with educational researchers at the University of Washington, Ocean Inquiry Project (OIP) is using a virtual learning environment based on a numerical-model of Puget Sound in introductory college level classes. OIP also provides students field-based research experiences on Puget Sound, sampling the Sound at a number of monitoring stations during day-long field trips. The learning goals for either technique are the same: understanding and appreciation of tidally driven currents and stratification in the Sound. However, the data (and tools for accessing and rendering them) are quite different between the two techniques, one being generated by computer and the other measured by the students themselves.
We are evaluating classes using each technique exclusively, as well as in combination, to understand which technique is most useful to understanding these concepts. The content of both classes is essentially the same, but students in one class learn the material by interacting with a computer model, and students in another class learn by interacting with instruments. The evaluation of each class is done identically with tests and concept maps and the design of this study allows us to elucidate the differences between learning via computerized curriculum and learning in the field.

Figure 1: The rated true/false quiz that we used for evaluation is shown above. Questions were apportioned into “field”, “model” and “classroom” groups for comparison (classroom questions are those not specific to either field or model experiences). Students rated each statement 5 (true) to 1 (false); 0 was used for “Don’t know”, a response seen mostly on pre-tests.
