SEA Semester - A Review

Transcription

1 SEA Semester : The Global Ocean Data Communication & Visualization CAS NS 330 (3 credits) Course Catalog Description (max. 40 words): Information visualization strategies and associated software, emphasizing communication to diverse audiences. Select between geospatial (GIS) and qualitative data foci. Develop graphics and/or multimedia products supporting research projects in concurrent courses. Compile iterative digital portfolio. Instructor(s): Sea Education Association Faculty Location: SEA campus in Woods Hole, MA and at sea on board one of SEA s sailing school vessels. Prerequisites: Admission to SEA Semester. Sophomore standing or consent of instructor. Course Philosophy and Approach: Research projects begin with questions, which we attempt to answer through collecting and analyzing information. How we then share our data and conclusions is the subject of this course. Effective and engaging communication skills enable us to convey complex information to a diverse audience both orally and in print. In Woods Hole, students will be introduced to models for organizing information, but will quickly focus on a project that will be pursued with a mentor on the ship and/or in our port stops. The independent research project will culminate in a conference- style presentation with effective visuals (charts, graphs, maps and images) in the form of an illustrated lecture or poster, or a written report of publishable quality. The data for this project may come from SEA s extensive research data, or be generated during the cruise. This course consists of 11 lecture/discussion sessions on shore (2 hrs each), 6 software work sessions with instructor available (1 hr each), 6 individual portfolio progress review meetings (1 hr each), and a student- led presentation session (2 hrs). An additional 20 hrs of guided and supervised project work will complement the formal class meetings. Learning Outcomes: 1. Familiarity with a minimum of three graphs, maps, infographics, matrices and/or multimedia pieces, and the software fundamentals needed to generate these products. 2. Ability to select the most appropriate information display strategy, accompanying text and formatting details for a given data objective and audience. 3. Effectively employ a broad range of visual communication techniques in publishable elements to support and enhance a field research project.

2 SEA Semester : The Global Ocean Symposium Presentation and Peer Critiques Project Drafts Portfolio Assignments: 10% 20% 20% Exercises (11): Short practice exercises require that students work with the software and strategies introduced in class, then apply them to new datasets or problems. These assignments occur during the first six weeks of the course between consecutive class sessions. Critiques (4): Write a short critical analysis of two visualization examples, one you believe to be effective and one you believe to be bad. Describe the effectiveness of the visualization, its most noticeable elements and their relative importance to the story, any essential missing information, elements that carry no information, and suggestions for how the visualization could be improved. Each critique should include a citation describing its source (publication information, author, web link, date). Be prepared to share and discuss your thoughts with the class. Occurs in weeks one, two & four; in week three, students critique their own work from practice exercises to date. Proof of Concept: With the assistance of the course instructor, identify and acquire a dataset comparable to that which you intend to collect/compile for your independent culminating project in marine policy, social science or oceanography. Based on your research objectives and planned approaches, create a suite (3-5) of graphics utilizing the example dataset that demonstrate your ability to carry out the intended project analyses. For each graphic, prepare appropriate accompanying text. Additionally, write a summary statement that justifies your data visualization method and display choices, and describes how each graphic serves your larger research objectives. Finally, outline your complete analytical plan for the subsequent portfolio work, including all proposed graphics this will provide you and the course instructor a shared baseline for the work you will submit for review during the second half of the course. Symposium: All students will share their Proof of Concept graphics suite for review by peers & faculty. Each will discuss their project focus and objectives as well as receive suggestions for alternative data visualization approaches in both written and verbal formats. Project Drafts and Portfolio: During the second half of the course, students will create and iteratively revise a series of data visualizations specific to their marine policy, social science or oceanography research project. The focus remains on development of graphics that highlight major project findings and complement written products, both for web publication. Students will share three rounds of drafts with the course instructor for evaluation and feedback (weeks eight, ten & eleven). A portfolio of revisions will be maintained for growth assessment and serve as the final assignment for this course (due week twelve). Expectations and Requirements: Punctual attendance is required at every class meeting. Active participation in class discussion is expected. Late assignment submissions are not accepted.

3 SEA Semester : The Global Ocean The policy on academic accuracy, quoted below, will be strictly followed in this class. The papers that you submit in this course are expected to be your original work. You must take care to distinguish your own ideas & knowledge from wording or substantive information that you derive from one of your sources. The term sources includes not only published primary & secondary material, but also information & opinions gained directly from other people & text that you cut & paste from any site on the Internet. The responsibility for learning the proper forms of citation lies with you. Quotations must be placed properly within quotation marks & must be cited fully. In addition, all paraphrased material must be acknowledged completely. Whenever ideas or facts are derived from your reading & research, the sources must be indicated. (Harvard Handbook for Students, 305) Considerations for use of internet sources: As you browse websites, assess their usefulness very critically. Who posted the information & why? Can you trust them to be correct? Authoritative? Unbiased? (It s okay to use a biased source as long as you incorporate it knowingly & transparently into your own work.) Keep track of good sources that might be useful for subsequent assignments, & annotate in your bibliography any sites you cite. Your annotation should include the name of the author or organization originating any material that you reference. If you can t identify the source, don t use it!
