A unique approach to introductory oceanography facilitates student understanding by integrating boat-based research and science content knowledge through the study of the local estuary. 60 Ocean Research College Academy (ORCA) students participate in two research cruises in the 10-week quarter, utilizing a YSI instrument and CastAway CTD for dissolved oxygen, temperature, salinity, and pH. Additional tools collect water samples with a Niskin for micronutrient cycling and a Ponar grab for benthic sediment to be tested for heavy metals. Each class contributes new data to the longitudinal study that was established 10 years ago. Class and laboratory time are a balance between the introduction of content knowledge of physical, geological, and chemical oceanography and facilitation of student research projects. A systems-based approach is used as students build on their understanding of the local estuarine environment and distinguish between regional and global processes. Inquiry-based techniques are used as students ask their own questions and design small-group research projects to investigate, analyze and interpret their data set while showing a command of the course content. Furthermore, students share their results at undergraduate research showcase events. Mastery of content knowledge, science writing and communication skills are measured through individual essay exams and a group research paper. Student self-reflection in 2015 showed that 95% of the students recognized improvement of their science writing skills and the value of systems-thinking in providing a deep coverage of oceanography. Further pre- and post-surveys will be analyzed to demonstrate the effectiveness of this approach.
