Therefore, the College has focused on six foundational skills that we feel will help students achieve greater success in college as well as in their career. The student will be expected to meet minimum levels of achievement for graduation in these six competencies: Written Communication Oral Communication Critical Thinking Critical Reading Quantitative Reasoning Information Literacy Written Communication: Students’ writing skills will be measured by their ability to articulate their understanding in writing on exams, in project presentations, and in online discussions. Oral Communication: Students’ oral communication skills will be measured by the quality of their engagement in class discussion and collaborative group work, especially during lab activities. Students will be expected to orally articulate their reasoning for their predictions and interpretations of data. Critical Thinking: Students’ critical thinking skills will be measured by the process of inquiry encouraged by the active classroom activities, and by their self-directed projects. Critical Reading: Students’ critical reading skills will be measured by their ability to critically review and evaluate online resources of information and other students’ written work. Quantitative Reasoning: Quantitative reasoning is a pervasive part of this course. Students will have to use mathematical models of functional relationships of measurable quantities, analyze data quantitatively, and be able to interpret visual displays of quantitative data. Information Literacy: Students will be researching physics topics of their own choosing. REQUIRED TEXT: Knight, Jones & Field (2010) College Physics 2nd Edition Addison-Wesley with accompanying Student Workbook, vols. 1 & 2, and code to register for Mastering Physics (online homework and tutoring system). Required: Calculator (scientific- trigonometric functions, exponentials, logs, etc.) COURSE ACTIVITIES This course is taught in a “workshop” style where traditional lecture, lab, and recitation type activities are integrated. Every class will include a variety of components. Students will be guided to consider what gaps may exist in their present understanding of the natural phenomena under consideration. Students will work collaboratively in groups within a process of guided inquiry. Student groups will share their predictions and thinking with other groups by using group whiteboards. Students will experience hands-on exploration of natural phenomena, often using their own bodies for kinesthetic and other sensory input. Students will collect data using computer interfaced sensors, and then interpret and analyze the tabular and graphical data output. Students will use video for computerized motion analysis. Educational interactive simulations, both in class and for online homework, will be used to explore concepts concerning those aspects of topics that are not visibly apparent. Students will work collaboratively in groups to practice applying newly learned physics concepts to superficially different or increasingly complex scenarios. Group work is done on group whiteboards. Extensions of those scenarios may be given for individual practice at home. Further individual practice applying physics concepts will be available using the workbooks that accompany the text and the online Mastering Physics online tutorial and homework system that includes the end of chapter questions from the text. The text will provide additional perspectives and will reinforce and supplement the material covered in the class activities. Frequent short quizzes, either online or in class, will give feedback to students about their progress. The students will be self directed with a project, of which the topic will be of their choosing, within the guidelines of their instructor. They will post their project online for commentary and discussion by other students. OUTCOME ASSESSMENT Exams: 50% Example: 30% 4 topic exams – the lowest exam score may be dropped 20% Cumulative Final Exam Projects/Papers: 20% Example: 15% Submitted in stages online 5% Discussion and comments on each others’ projects online Homework: 15% Example: 10% Mastering Physics online 5% Workbook, Interactive Website comments, and Homework related to class activities Class Activities: 15% Example: 5% Attendance and Effort 5% 5% Quality of participation 5% 5% Quizzes based on previous class activities Assessment category percentages may vary slightly with instructor. COURSE POLICIES 1. Attendance Policy – It is assumed that a student will attend all classes for which he/she is registered. Ceasing to attend classes for three consecutive class meetings without contacting the instructor will result in the issuance of a grade of “FW” which indicates “stopped attending.” This grade of “FW” will be calculated into the student’s GPA as an “F” and may result in dismissal. In addition this status will be reported to The Office of Student Services and may result in a reduction of financial aid monies. Because this course is participatory in nature and has integrated lab and group activities, attendance is necessary to do well in the course. Expect lack of attendance or frequent lateness to be reflected in the course grade. 2. Cheating and Plagiarism – Cheating and plagiarism are contrary to the purpose of any educational institution and must be dealt with most severely if students’ work is to have any validity. An instructor who determines that a student has cheated on a test or assignment will at a minimum give a zero for that item and may give a failure for the course. Normally the matter is handled between the instructor and the student, but either party to ensure fairness may consult the department chairperson. Suspicion of cheating on exams (e.g. as when two students sitting next to each other have unnaturally similar answers) will result in another exam taken in place of the original by all parties involved. Plagiarism, which is the appropriation of words or ideas of another without recognition of the source, is another form of cheating. An instructor who determines that a student has plagiarized will give a zero for the paper or project and may give a failure for the course. Both cheating and plagiarism are grounds for dismissal from the College. Any action taken regarding cheating or plagiarism is subject to the Academic Grievance Policy outlined above and in the Student Handbook. 3. Cell Phone Use – Cell phones should be turned off prior to the start of class. Students that do not abide by this policy may be asked to leave for the day and will receive an unexcused absence.
