Course Requirements

Prerequisites: MATH 1414 with a C or higher Or appropriate score on the ACC Higher Level Mathematics Placement Test.

Importance of Prerequisites: This is not a review course.  If you do not have current knowledge of the material in our MATH 1414 College Algebra for Precalculus, please ask your instructor about changing to a different course to better prepare for MATH 2412.

Required Materials 

This is a First Day™ class. The cost of required course materials, including an online version of the textbook and ALEKS, has been added to your tuition and fees bill. ALEKS is required in this course.

 

Use of Graphing Utilities:  We will use graphing calculators and/or graphing software when their use enhances the understanding of a mathematical idea.  Graphing calculators are not required for this course. However, it is required that you have access to some technology that allows you to graph functions and find their zeros.  Most ACC faculty are familiar with the TI family of graphing calculators. Hence, TI calculators are highly recommended for student use. Other calculator brands can also be used. Your instructor will determine the extent of calculator use in your class section.

Other Technology: Access to a webcam and microphone are required for this course. Eligible students can check out required technology at https://www.austincc.edu/students/student-technology-services.

 

Making Time to Learn

We learn math by thinking about and working on mathematical problems, which takes time. Practice is crucial in a math course. To ensure that you have adequate time, set aside 8-12 hours per week outside of class time to practice and study for this course.  Ask for help immediately when something isn’t clear. 

Getting Help

ACC provides several free resources for students who need help; descriptions and links are below: 

Office hours: Another name for office hours is “student hours.” This is the time your instructor has set aside to answer student questions, so feel free to drop by if you have questions. Office hours may be virtual or on campus; see information above.

Instructional Associates: Instructional Associates specific to the course you are taking are available for tutoring. To make an appointment, go to https://sites.google.com/a/austincc.edu/math-students/meet/list and then click on your course.

Where can I find my grades?

Grades will be posted in Blackboard.

What will we do in this class?

Tests:

There will be 3 exams, each of which will count 20% of your overall course grade, and a fourth exam which is a cumulative final and is worth 25% of your overall course grade.  The dates of the exams are noted on the schedule, always on the Wednesday of the exam week. All tests will be administered in class. Partial credit is given on exams when the answer is wrong, but when the methods used are partially correct.  However, the amount of partial credit given on exams is at the discretion of the instructor.

Homework:

ALEKS Homework and Written Homework will be assigned every week on Wednesday (Written Homework is assigned in Blackboard in the Homework Box) and is due before class the next Wednesday.  Instructions on how to access ALEKS and the Blackboard Homework Box will be discussed on the first day of class. Both ALEKS Homework and Written Homework are required.

It is vital that students NOT get behind on homework. Make use of tutoring resources and office hours if you have questions about the homework.  You may work in groups on homework, but the homework you submit must represent your own work. Get help when you need it, but don’t abuse tutors, professors, or others.  You need to learn how to set up and solve the problems yourself.  If you don’t, then you will not do well on the tests.

What happens if I miss something?

Dropped Grade Policy: The lowest three Written Homework section grades will be dropped for computing the final grade.  No ALEKS Homework grades or Exam grades will be dropped or replaced.

Late Homework Policy: Late homework assignments will rarely be accepted under any circumstances.

Missed Exam Policy: Missing an exam is very serious and should be avoided if possible. A makeup exam will only be given in the case of a genuine emergency or extreme illness (with appropriate documentation), and at the discretion of the instructor. Makeup exams are disruptive and inconvenient to both the student and the instructor. If you know that you must miss an exam, contact the instructor well in advance of the exam date to determine the best course of action.

Attendance/Class Participation: Daily attendance is mandatory.  Any student who has five or more absences may be withdrawn by the instructors, but we make no promise to do so.

Any absences will be recorded in the Blackboard gradebook under “Absence Count”.  The Absence Count is not used in any way to compute the final grade. Note: if the Absence Count is zero, it means that you have zero absences.

There is no such thing as an “excused absence”. The result of missing a class is the same regardless of the reason. You miss instruction. You miss an opportunity to ask questions. The goal is to minimize these disruptions, and to take personal responsibility to make up for any missed class on your own time.

Regular and punctual class and laboratory attendance is expected of all students.  If attendance or compliance with other course policies is unsatisfactory, the instructor may withdraw students from the class.

In the event the college or campus closes due to unforeseen circumstances (for example, severe weather or other emergency), the student is responsible for communicating with their professor during the closure and completing any assignments or other activities designated by their professor as a result of class sessions being missed.

The Details

First Day Access: To enhance your learning experience and provide affordable access to the right course material, this course is part of an inclusive access model called First Day™. You can easily access the required materials for this course through Blackboard, at a discounted price, and benefit from single sign-on access.  Austin Community College includes the discounted price as a course fee in your registration fees for this course.

It is NOT recommended that you Opt Out, as these materials are required to complete the course. You can choose to Opt Out on the first day of class, but you will be responsible for purchasing your course materials at the full retail price and access to your materials may be suspended. See your course in Blackboard for details.

Withdrawal Policy: It is the responsibility of each student to ensure that his or her name is removed from the roll should he or she decide to withdraw from the class. The instructor does, however, reserve the right to drop a student should he or she feel it is necessary. If a student decides to withdraw, he or she should also verify that the withdrawal is submitted before the Final Withdrawal Date. The student is also strongly encouraged to retain their copy of the withdrawal form for their records.

Students who enroll for the third or subsequent time in a course taken since Fall 2002 may be charged a higher tuition rate for that course.  State law permits students to withdraw from no more than six courses during their entire undergraduate career at Texas public colleges or universities. With certain exceptions, all course withdrawals automatically count towards this limit. Details regarding this policy can be found in the ACC college catalog.

Reinstatement Policy: Students who withdrew or were withdrawn will not be reinstated unless they have completed all coursework, projects, and exams necessary to place them at the same level of course completion as the rest of the class. Reinstatement is up to the instructor’s approval.

Incomplete Grade Policy: Incomplete grades (I) will be given only in very rare circumstances. Generally, to receive a grade of "I", a student must be up to date on coursework and have a passing grade, and after the last date to withdraw, have a legitimate reason that prevents course completion. An incomplete grade cannot be carried beyond the established date in the following semester. The completion date is determined by the instructor but may not be later than the final deadline for withdrawal in the subsequent semester.

Communication with Your Instructor: All e-mail communication to students will be sent solely to the student’s ACCmail account or math software if applicable, with the expectation that such communications will be read in a timely fashion.  Likewise, students should use their ACCmail account or math software when communicating with instructors.  Instructors will respond to student emails within 3 business days, if no response has been received by the student at the end of that time, then the student should send a reminder to the instructor.
