Overview. The goal of the course is to allow the student to gain mastery over plane geometry so that the student may effectively teach the subject at the high school and college level. The course will cover Book I of Euclid's Elements with the due rigor necessary to achieve this goal.
Meeting Time and Location. MWF, 3:30-4:20, SCHM 123
Textbook. The textbook for the course is "Euclid's Elements" as translated by Thomas L. Heath. A pdf of course notes will also be distributed.
Contact. The best way to contact me is by email. My email address is tsincla(at)purdue.edu. I will usually respond to emails fairly promptly during normal business hours. If you have not received a reply within 48 hours, feel free to follow up.
Office. My office is 744 in the Mathematical Sciences building.
Office Hours. See the course Brightspace page for details. Outside of regular office hours, I am also happy to meet by appointment. Please email me to schedule.
Brightspace. The course page on Brightspace will serve as the main point of contact for announcements, assignments, course policy, and virtual content. Students will be expected to check the course page regularly, at least before every class meeting.
Gradescope. Assignments and quizzes must be uploaded to Gradescope via the course page in Brightspace. (Select "Content" from the top pane in the Brightspace course home page then look for the "Gradescope" tab on the left.) No hard copies of assignments or quizzes will be accepted.
Course Notes. Handwritten course notes will be available in a OneNote Notebook accessible from the course Brightspace page under "Content/Course Notes."
Academic Calendar For ease of reference, here is a link to the academic calendar detailing all breaks, add/drop deadlines, etc.
Lecture. Lectures are held in-person. Due to the interactive nature of the course, attendance is mandatory. Class cancellations and other changes due to a health-related absence on my part will be communicated via the course page in Brightspace.
Accommodations. Purdue University strives to make learning experiences accessible to all participants. If you anticipate or experience physical or academic barriers based on disability, you are welcome to let me know so that we can discuss options. You are also encouraged to contact the Disability Resource Center at: drc@purdue.edu or by phone at 765-494-1247.
If you have been certified by the Disability Resource Center (DRC) as eligible for accommodations, you should contact your instructor to discuss your accommodations as soon as possible. Here are instructions for sending your Course Accessibility Letter to your instructor: https://www.purdue.edu/drc/students/course-accessibility-letter.php.
Exams. There will be no exams for the course.
Attendance. Attendance will be recorded at several points throughout the course.
Quizzes. There will be 6 quizzes in total for the course. The quizzes will be administered online through Gradescope. Each quiz will consist of several response questions. There will be a three day window to take each quiz, but quizzes will have a time limit from when they are open to complete and upload solutions. The lowest quiz score will be dropped.
Homework. There will be 12 homework sets assigned on a near-weekly basis. Homeworks will be assigned on Fridays and due the following Friday. (See below for details and due dates.) Students are encouraged to collaborate on homeworks as long as each student turns in their own, individual work. Rote copying of solutions from peers, internet forums, or plagiarism of any kind will not be tolerated. The lowest two homework scores will be dropped.
Homework Formatting. Homeworks must be typed or neatly written and scanned. Students are encouraged to prepare assignments using LaTeX (see the section on LaTeX below) or other word processing application. There should be no significant cross-outs, rewrites, scratchwork, scribbling, etc. Problems should be clearly indicated and be placed in the correct sequence. Homework should be uploaded to Gradescope by 5:00 pm on the Monday after the due date.
Presentations. Students will be assigned to give in-class presentations over assigned homework problems. Presentations will be graded on correctness, clarity, organization, and audience engagement.
Grades. There will be 140 total points. Homework will be worth 5 points per assignment (50 points total). Quizzes will be worth 6 points each (50 points total). Presentations will be worth 30 points total, and Attendance will be worth 10 points total. Grades will be determined by percentage of total points earned. For marginal cases, there will be some discretionary leeway in final grade assignment to account for course participation/engagement or extraordinary effort. Students who get at least 97% of the total points in this course are guaranteed an A+,93% guarantees an A, 90% an A-, 87% a B+, 83% a B,80% a B-, 77% a C+, 73% a C, 70% a C-, 67% a D+, 63% a D, and 60% a D-. The following is a sample cutoff distribution which is fairly typical for courses I have previously taught. The final grade cut-offs may differ slightly. A >92, A- >88, B+ >85, B >78, B- >74, C+>70, C> 65, C- >60.
LaTeX is the language for mathematical typesetting. If you are a CS, Math, or Stats major, I would strongly recommend becoming proficient in LaTeX. Here is the link to A.J. Hildebrand's excellent (archived) collection of beginner LaTeX resources. Another great place to start is Jon Peterson's advice and resources for new researchers. You will probably also frequently need to consult the LaTeX Wiki.
Academic Integrity. See the Academic Integrity webpage from the Office of the Dean of Students. Penalties for academic dishonesty will be, at minimum, a score of zero on the quiz or assignment. Egregious cases will be referred to the Dean of Students and may result in failure of the course or expulsion.
General Policies. General policies applying to all courses university wide can be found in the course Brightspace page under "Content/University Policies and Statements."
