Student Responsibilities
- You should read over this syllabus carefully, as I will
hold you responsible for the information herein.
- Students will be expected to read the chapters
carefully, including the examples in the book.
- Students will be responsible for obtaining any and all
handouts. If you are not in class when handouts are given, it is your
responsibility to obtain copies.
- You should begin working now. Frequent practice is
crucial to the successful completion of a mathematics course. Cramming at
the last minute will certainly lead to failure.
- WARNING: If you are in academic trouble, or are in danger of
losing your financial support, or if your parent or guardian is expecting
a certain grade at the end of the semester... start working today. I will
refuse to listen to any pleas at the end of the semester. You will receive
precisely the grade that you earn.
Grading Policies
The following schedule is tentative and is subject to capricious changes in case of extracurricular events deemed sufficiently important to the upper administration.
|
|
Cooperation is encouraged in doing the homework assignments. However, cheating will not be tolerated on the exams. If you are caught cheating, you will be subject to any penalty the instructor deems appropriate, up to and including an automatic F for the course.
Attendance is not required for this class. However, you will be responsible for everything that I cover in class, even if you are absent. It is my experience that students who skip class frequently make poorer grades than students who attend class regularly. You should consider this if you don't think you'll be able to wake up in time for class consistently.
The grade of "I" is designed for students who are unable to complete work in a course but who are currently passing the course. The guidelines are clearly spelled out in the Student Handbook. Before you ask, you should read these requirements.
Exam Policies
- Unless announced otherwise, calculators will not
be permitted for use on exams.
- I expect to give exams during the weeks above. However,
these are tentative dates. I will announce the exact date of each exam in
class.
- After exams are returned in class, you have 48 hours to
appeal your grade. I will not listen to any appeals after this 48-hour
period.
- I will not drop the lowest exam score; all will count
toward the final grade.
- No make up exams will be given. For those students who
miss an exam due to an Authorized Absence (see the Student
Handbook), the final grade will be computed based only on those exams
taken, together with homework/quiz scores and the final exam. Such
students will be required to provide official written verification
of such an absence.
- Students missing an exam for unauthorized reasons will
receive 0 (zero) points on the exam.The Final
Examination will be comprehensive in the sense that problems may come from
any of the sections that will be covered during the semester.
- The grade of A signifies consistent excellence
over the course of the semester. In particular, an A on the final is not
equivalent to an A for the course.
- I reserve the right to test and quiz you on problems
which are generalizations of material covered in the class and/or in the
text. In short, the problems may not look exactly like the ones in the
book.
- Everything that I say in class on Mondays and
Wednesdays is fair game for exam material. You will be responsible for
everything unless I advise you to the contrary.
- You will not be held responsible for the
certification exam preparations, Friday presentations, or the two class
projects on the exams.
Homework Policies
- Homework will be assigned every Friday and will be due the following Friday. All assignments will be posted online.
- Most weeks, you will be expected to work on four different assignments at once: (1) homework based on the Monday/Wednesday lectures, (2) preparation for the TExES Mathematics 8-12 certification exam, (3) Friday presentations, and (4) two different class projects.
- I expect the assignments that you turn in to be written up carefully and neatly, with the answers
clearly marked. You must show all of your work. Messy homework will not
be accepted.
Homework based on the Monday/Wednesday lectures
- Entire homework assignments will not be graded.
Instead, only five representative problems will be graded per assignment.
As a consequence, it will be possible to not do the entire assignment and
still receive a perfect score on that particular assignment. Deliberately
leaving homework uncompleted is highly unrecommended,
however, as the law of averages will surely catch up with you as the
semester progresses.
- When computing grades, I will drop the two
lowest homework grades before computing the homework average. Therefore,
in principle, you could get a 100% homework score and also not turn in two
assignments during the semester. I have this policy in case you get sick, a family emergency arises, etc., during the
semester. You will still be responsible for the material in such
assignments during the examinations.
- Because of this policy, I will not give
extensions on homework assignments, nor will I accept late assignments.
Certification exam preparation
- Every week, you will be given about 12-18 problems on
topics pertinent to the Mathematics 8-12 certification exam. These are
mostly chosen from problems that appeared on Precalculus
and Calculus I exams given by your instructor to TAMS students in past
years.
- For each assignment, you will also choose 5 problems
from the remaining preparation problems. If you submit more than five such
problems, the grader will simply grade the first five problems on the
homework assignment.
- When computing grades, I will drop the two
lowest grades before computing the certification exam preparation average.
Because of this policy, I will not give extensions on the
certification assignments, nor will I accept late assignments.
Friday presentations
- Every week, selected problems from a collection of hard questions from real high school
students will be posted. Every Friday, students will be sent to the
board, one at a time in random order, to demonstrate how they would answer
these questions if posed by a future high school student.
- With these presentations, you should develop two
important skills: solidifying your content knowledge of secondary
mathematics and learning how to "sell" difficult ideas to your
future students.
- All presentations will be peer graded.
- If you get called to the board on a Friday but have an
unexcused absence, you will get a 0 for this presentation.
- All presentation grades will be used to compute the
Friday presentations average.
- If you really mess up on a presentation --- or are
called to the board on a day that you miss class --- you are permitted
once during the semester for a second-chance session to be scheduled with
your instructor. At such a session, you will be asked to be prepared to
answer about ten of these questions, actually answer maybe three or four,
and will be directly assessed by your instructor.
Class projects
- The class project concerns developing ideas to sell
course content to high school students that may not like mathematics as
much as you do.
Final Notes
- For the sake of completeness, I list some other areas
that new teachers struggle with, according to experienced secondary
teachers:
- Being willing to seek
advice from seasoned instructors
- Covered the whole
curriculum over the course of a year without getting bogged down on
specific topics
- Classroom management
- Keeping appropriate
documentation (e.g., special-needs students, communication with parents,
etc.)
- Appropriate use of
classroom technology
- Being consistent in
enforcing discipline
- Keeping authority
(i.e., not just being a pal to one's students)
- Maintaining
professional distance
· The University of North Texas makes reasonable academic accommodation for students with disabilities. Students seeking accommodation must first register with the Office of Disability Accommodation (ODA) to verify their eligibility. If a disability is verified, the ODA will provide you with an accommodation letter to be delivered to faculty to begin a private discussion regarding your specific needs in a course. You may request accommodations at any time, however, ODA notices of accommodation should be provided as early as possible in the semester to avoid any delay in implementation. Note that students must obtain a new letter of accommodation for every semester and must meet with each faculty member prior to implementation in each class. For additional information see the Office of Disability Accommodation website at http://www.unt.edu/oda. You may also contact them by phone at 940.565.4323.
