How is the Grading will be based primarily on the successful completion of homework course graded? assignments. The homework assignments will be used to acquire points that will be totaled at the end of the course and used to determine your final letter grade. Other graded assignments may include quizzes, exams, laboratory reports, and/or writing assignments. A final examination is likely. A list of probable homework assignments is given on page 5 of this syllabus; please bear in mind that the list is schematic and is subject to change as the semester progresses. At the end of the course your percentage of the total available points will be computed; your letter grade will be determined by reference to the following table: Minimum % Letter Grade Maximum % 96 A 100 91 A‐ 95 88 B+ 90 84 B 87 81 B‐ 83 76 C+ 80 71 C 75 60 D 70 0 F 59 How will the Most of the assignments in this course are Excel‐based computer programs computer that will be implemented using VBA. These assignments will be scored as programming follows: assignments Grade Level of Achievement be graded? A The program computes correct quantities for all conditions described in the assignment. The code is thoroughly annotated, meaning the variables and procedures are explained in sufficient detail so that you will be able to understand what you did well into the future. AE 597E: Color Science for Illuminating Engineering Page 2 of 5 Syllabus v1 (25 August 2009) B The program works for all conditions, but the annotations are not thorough, your code is difficult to follow, and/or the graphical output is poorly organized. Or, the program works for nearly every condition described in the assignment, but minor problems may occur. C Nearly all of the routines in the program work correctly, such as the computation of intermediate parameters. You’ve reported these parameters so that they can be easily checked. But, the code is not fully debugged. Different errors may occur for different types of input. D There are logical problems. The program “runs”, but many quantities are computed incorrectly. F There are serious logical problems. The program may “run”, but most quantities are computed incorrectly. Why is the This is an example of “criterion‐referenced grading”, which means that your course graded grade will be determined by the established standards for this course, not by this way? comparing your performance to that of your classmates. The assumption is that the standard of performance is reachable by all: everyone could get an ‘A’, and likewise everyone could get an ‘F’. How will my Assignments will require a paper‐based deliverable, electronic deliverable, work be oral presentation, or some combination. You will be informed of the evaluated? evaluation criteria on an assignment‐by‐assignment basis. The only way that your work can be evaluated is on the materials produced. It is impossible for me, and unfair to the class as a whole, to consider the workload from other classes or outside commitments. These factors will not be considered as part of your evaluation. Professionalism in this course is as important as in the workplace, and included such traits as preparation, productivity, and promptness. Cell phones, email, instant messaging and all other potential distractions will not be tolerated during our regularly scheduled class meetings or during visits to my office. Class periods will be interactive and will have a discussion component. It is therefore important for you prepare for class by completing the readings and assignments. Active participation is expected. Participation and professionalism will contribute to your final grade. Why does the The class meets twice each week for a 100 minute period that will be used for class meet for a lecture, discussion, lab exercises, and problem solving. On average, we will double period? meet for 150 minutes per week. The double period allows for some flexibility in running laboratory exercises, and also to compensate for the occasional cancelled class due to the instructor’s travel schedule. How much time Plan to spend at minimum an additional nine hours per week on the should I expect assignments. It may (and will likely) take more than nine hours per week to spend? outside of class to excel in this course. AE 597E: Color Science for Illuminating Engineering Page 3 of 5 Syllabus v1 (25 August 2009) What is the Regular and punctual attendance is your responsibility. A good engineer attendance upholds professional conduct by always being prompt. If this is not your habit, policy? acquire it. It will help you in this class and in your career. What is the Unless otherwise written on an assignment or announced by the instructor, policy about assignments are due at by the beginning of class. Late work will not be late work? accepted, please don’t even ask. What is the Open discussion and the public exchange of ideas are healthy parts of the policy about learning process and university life. You are encouraged to discuss the course, working in exchange ideas, and work on assignments with your classmates. Keep in mind teams? that there is an implied reciprocity associated with working together, solving problems together, and learning together. It is expected that in some instances your classmates will be a resource for you, while at other times you will be a resource for them. Also keep in mind that working together is a means, not an end. Ultimately, you need to know what you’re doing, and you alone are responsible for the work you turn in. What Talking over your ideas and getting comments on your work from classmates, constitutes co‐workers and instructors are not examples of plagiarism or cheating. Taking academic someone else’s work and calling it your own is plagiarism, including using dishonesty? another persons’ calculations, spreadsheets, computer programs, homework solutions, or ideas. Academic dishonesty includes, but is not limited to, cheating, plagiarism, fabrication of information or citations, facilitation of acts of academic dishonesty by others, unauthorized possession of examinations, submitting work of another person or work previously used without informing the instructor, and tampering with the academic work of other students. Such acts of dishonesty violate the fundamental ethical principles of the University community and compromise the worth of work completed by others. The minimum penalty imposed for academic dishonesty of any type will be a grade of ‘F’ for the assignment. More serious offenses will result in failure in the course and major offenses may result in suspension or expulsion from the University. You are encouraged to read the University Code of Conduct and Faculty Senate Policy 49‐20 and G‐9 Procedures. What about In compliance with Pennsylvania Department of Health and Centers for special Fall Disease Control recommendations, students should NOT attend class or any 2009 Flu public gatherings while ill with influenza. Students with flu symptoms will be protocols? asked to leave campus if possible and to return home during recovery. The illness and self‐isolation period will usually be about a week. It is very important that individuals avoid spreading the flu to others. Most students should be able to complete a successful semester despite a flu‐ induced absence. Faculty will provide students who are absent because of illness with a reasonable opportunity to make up missed work. Ordinarily, it is inappropriate to substitute for the missed assignment the weighting of a semester's work that does not include the missed assignment or exam. Completion of all assignments and exams assures the greatest chance for students to develop heightened understanding and content mastery that is unavailable through the weighting process. The opportunity to complete all assignments and exams supports the university's desire to enable students to AE 597E: Color Science for Illuminating Engineering Page 4 of 5 Syllabus v1 (25 August 2009) make responsible situational decisions, including the decision to avoid spreading a contagious virus to other students, staff, and faculty, without endangering their academic work. Students with the flu do not need to provide a physician's certification of illness. However, ill students should inform their teachers (but not through personal contact in which there is a risk of exposing others to the virus) as soon as possible that they are absent because of the flu. Likewise students should contact their instructors as quickly as possible to arrange to make up missed assignments or exams. If you have questions about academic policy‐related issues, please call the Associate Dean/Chief Academic Officer of your college. For health‐related questions you can email Dr. Margaret Spear, director, University Health Services, at firstname.lastname@example.org.
