Western College: OCN 110 Oceanography Writing Across the Curriculum Rationale: Mohave Community College firmly supports the idea that writing can be used to improve education; students who write in their respective content areas will learn more and retain what they learn better than those who don t. Courses in the core curriculum have been identified as Writing Across the Curriculum courses. Suggested minimum standards for the Writing Across the Curriculum component are as

3 3 follows: 1. The writing assignments should total words. For example, a single report which is 1500 words in length could fulfill the requirement, or a series of essay questions and short papers (example: four -375 word assignments) which total 1500 words could meet the requirement. 2. The writing component will represent at least 10% of a student s final grade in the course. Is this a course identified as a Writing Across the Curriculum course? X Yes No Intended Student Learning Outcomes By the end of the semester students will be able to: 1. Describe the distribution of continents and ocean basins, the major features of each ocean basin (ridges, rises, faults, trenches and fracture zones) and the processes that create volcanic islands, atolls and coral reefs. 2.

Moran Publisher American Meteorological Society ISBN Software Equipment Title AMS Ocean Studies Investigations Manual & Summer 2009 Author(s) National Oceanic and Atmospheric Administration Publisher American Meteorological Society ISBN None required for students; instructor text comes with a faculty CD, which contains a faculty manual, chapter test bank questions, and textbook images. Test bank questions need to be converted via Respondus software, which DE has purchased. (Respondus usage is not limited to the materials for this course.) None Other Use of this text/investigations packet comes with a license ($249 annually, unlimited sections and unlimited students) that allows students to participate in online, real-time ocean investigations, called Current Ocean Studies. (NOTE: this course will be offered Spring 09 totally online. Distance Education has paid the first year license with no additional charge to students. In subsequent years the course will include a minimal lab fee to cover the license expense.) Current Ocean Studies offers 12 weeks of investigations, with one investigation per week. The Investigations Manual contains and Introduction and an Applications sections. The investigation can be completed using the two sections of the Manual or by using the Introduction section plus the real-time Current Ocean Studies posted to the Course Website (linkable from the MCC LMS site). The Manual Applications section and the Current Ocean Studies are similar in format, topic and length. (The Investigations Manual could function as a self-contained lab, but as long as the AMS delivery schedule works with MCC s academic calendar, as it does for fall and spring semesters, the real time resource is a great learning tool for students.)

9 9 Writing Across the Curriculum (See for sample grading rubrics) This course emphasizes and supports writing across the curriculum. Therefore, students will be required to complete writing assignments: essays, quizzes, and exams. Students may also be asked to submit essays using appropriate research methods using Modern Language Association (MLA) style citations. The students papers will also demonstrate their abilities to write critically about topics relevant to the relationship of the course material to world events. To this end, and to encourage students to integrate the concepts they learn in class with their practical applications, students may be assigned or be allowed to select one of ten critical thinking essays provided at the end of each chapter from the textbook and submit them to the instructor according to an established timetable. In addition, each student would be responsible for contributing weekly to the discussion board on the driving topic assigned for each learning unit. Alternatively, and at the discretion of the instructor, students may be assigned up to (10) critical analyses of articles from current scientific periodicals, or articles from the popular press, or the American Meteorological Society, dealing with relevant scientific subjects. The following guidelines should help students in the preparation of their critiques. 1. Begin with a complete bibliographic citation of your article. 2. Summarize the major ideas presented in the article. Ask yourself (and answer in your summary) questions like: a. What is the hypothesis? b. How is the hypothesis tested? c. What evidence is presented to support or refute the hypothesis? d. What conclusion did the author reach? 3. Critically analyze the article. Ask (and answer) questions like these: a. Were the experimental procedures adequate? b. Do you agree with the conclusions reached? c. Was the article written well? d. Do you think the topic is important? Why or why not? e. Did this article raise any new questions in your mind?
