2) Students will be able to interpret and/or draw inferences from mathematical models, data, graphs, or formulae.

Lectures
Lectures are very important for understanding the material and doing well on the exams, please attend!    Please participate via questions, answers, and comments. It is also important to do the homework assignments.

Attendance
Attendance is required.  Failure to attend regularly will put your success in the course (and your grade) in serious jeopardy.

Getting Help
Please contact me or the teaching assistant if you have questions or are having difficulties.  Office hours are regularly scheduled times that you can come by to ask questions or get help.  If you are unable to visit during scheduled office hours, contact myself or the teaching assistant  to set up an appointment.  

·         Disability Accommodations:  Students needing academic accommodations for a disability must first register with Disability Accommodations & Success Strategies (DASS).  Students can call 214-768-1470 or visit http://www.smu.edu/Provost/ALEC/DASS to begin the process.  Once registered, students should then schedule an appointment with the professor as early in the semester as possible, present a DASS Accommodation Letter, and make appropriate arrangements.  Please note that accommodations are not retroactive and require advance notice to implement.

 

·         Religious Observance: Religiously observant students wishing to be absent on holidays that require missing class should notify their professors in writing at the beginning of the semester, and should discuss with them, in advance, acceptable ways of making up any work missed because of the absence. (See University Policy No. 1.9.)

 

·         Excused Absences for University Extracurricular Activities: Students participating in an officially sanctioned, scheduled University extracurricular activity should be given the opportunity to make up class assignments or other graded assignments missed as a result of their participation.  It is the responsibility of the student to make arrangements with the instructor prior to any missed scheduled examination or other missed assignment for making up the work. (University Undergraduate Catalogue)

 

·         Final Exams:  Final course examinations shall be given in all courses where they are appropriate, and some form of final assessment is essential.  Final exams or final assessments must be administered as specified in the official examination schedule, and shall not be administered during the last week of classes or during the Reading Period.  Please state clearly in the syllabus the date/time and form of the final exam or assessment.

 

·         In accordance with Texas Senate Bill 11, also known as the “campus carry” law, following consultation with entire University community SMU determined to remain a weapons-free campus. Specifically, SMU prohibits possession of weapons (either openly or in a concealed manner) on campus. For more information, please see:  http://www.smu.edu/BusinessFinance/Police/Weapons_Policy.

 

 SMU Honor Code
