Course Goals/Core Goals:

Core Goals (for students using the 2013-2014 catalog or earlier catalog):

This course contributes to the science component of the core. The course is intended to enable students to continue to meet the following core goals:

1.      Demonstrate an effective level of cognitive, communicative, and research skills;

2.      Achieve a college level of computational skills and an ability to understand and interpret numerical data;

3.      Acquire a knowledge of the history and heritage of western civilization to include: c) scientific literacy through a knowledge of the history, the methods, and the impact of science on the individual, society, and the environment;

5.      Apply liberal learning in problem solving contexts as preparation for active participation in society;

6.      Make informed ethical decisions that promote personal integrity, the legitimate rights and aspirations of individuals and groups, and the common good.

Course Goals (QCM) (for students using the 2014-2015 catalog or later catalog):

This course satisfies the Computational, Mathematical, and Analytical Mode of Inquiry requirement (QCM).  This mode of inquiry introduces students to methods for analyzing and logically organizing information; formulating algorithmic solutions to problems; and utilizing data abstraction, modeling, interpretation and analysis.  Courses in this area should foster understanding of these techniques to levels that would enable students to generalize solutions and think abstractly beyond specific examples covered.

All QCM courses are designed to enable students to continue to meet the following student learning goals:

1a.  Demonstrate critical thinking and analysis  In this course, students will learn how to interpret problems and solutions in four different contexts, being able to work equally well in each context:  graphically, symbolically, numerically, and verbally. (Homework exercises and exams).

1b.  Identify, study, and solve problems  In this course, students will not only learn methods for solving problems, but why they work, when they are appropriate to use, and how to apply them to new settings.(Homework exercises and exams).

1c.  Achieve computational skills and an ability to understand and interpret numerical data  In this course, students will use a graphing calculator to solve problems and how to check whether their answer is reasonable or not. (Homework exercises and exams).

6a.  Develop intellectual curiosity and a desire for lifelong learning  In this course, students will be asked to consider why the techniques they are learning are important and will build a foundation of skills that future courses will build upon. (Homework exercises and exams).

7a.  Use knowledge, theories, and methods from the arts, humanities, natural sciences, and social sciences to raise and address questions germane to those areas of study  See previous goals..(Homework exercises and exams).

7d.  Explore connections between classroom and real-world experiences  In this course,students will learn applications of the material to solve real-world problems. Examples of applications in this course will be marginal cost, marginal profit, determining long term behavior, and optimizing a system of equations with business type constraints. (Homework exercises and exams).

Learner Outcomes:

Specific Course Goals (Student Learning Goals in parentheses):

  1. Evidence problem solving ability by demonstrating the following capabilities: understanding the problem, identifying the appropriate strategy to solve the problem, selecting the necessary tools to implement the strategy, evaluating the effectiveness of the strategy (1a, 1b, 1c, 7a, 7d)
  2. Evidence a mastery of algebra concepts and techniques (1b, 1c)
  3. Evidence an ability to solve systems of linear equations and to apply basic linear programming techniques (1a, 1b, 1c, 6a, 7a, 7d)
  4. Demonstrate an understanding of the concept of a limit and of continuity of a function together with an ability to calculate limits (1b, 1c)
  5. Demonstrate an understanding of the derivative algebraically as the limit of the difference quotient, geometrically as the limit of slopes of secant lines, and conceptually as a rate of change; also, evidence ability to compute the derivative of a function (1a, 1b, 1c, 6a, 7a)
  6. Evidence the ability to utilize technology in both computational and conceptual ways interacting with the above learner outcomes (1c, 7a)
  7. Develop enhanced written and oral communication skills in the area of scientific communication (6a, 7a, 7d)

These outcomes will be achieved through homework assignments and exams.

IDEA Objectives:
1.     Gaining factual knowledge (terminology, classifications, methods, trends). (Essential)
2.     Learning fundamental principles, generalizations, or theories. (Essential)
3.     Learning to apply course material (to improve thinking, problem solving, and decisions). (Important)

Your are expected to come to class regularly and on time.  You will not be admitted if you arrive more than fifteen minutes late. You are expected to work collaboratively or independently as assignments dictate and submit all required work on time.  Late papers will not be accepted. We are a community of diverse learners from diverse backgrounds; all class members should be treated with proper respect at all times.   I would expect that you will need to spend at least six hours per week outside of class on this course.   Be prepared to assimilate concepts over time, look at content from different perspectives, reflect upon your learning as the course proceeds.  Ask questions! No questions should remain unanswered, If there is material with which you are not fully comfortable, you are expected to ask questions either during class, during office hours, or electronically..

There is a significant amount of homework in this course. If you are struggling with the content, you may need to devote more than the recommended number of hours. Please seek appropriate assistance to help you complete your work within a reasonable amount of time.

Technology Requirement:

Students are expected to use D2L for all course communications, accessing notes and course information, and the completion of certain assignments as indicated in this syllabus. All written homework must be prepared using word processing software. A graphing calculuator is required for many activities and homework.

There are practice problems listed for each section of the text. These will not be collected. Some of these will be addressed in class. It is imperative that you attempt all problems as you read and re-read each section.

There will also be collected homework sets approximately each week. These will constist of 5-6 problems. Assignments will be completed individually.

Studying mathematics is a social process. Much benefit can be gained by sharing insights and by struggling through problems with your peers. Learn to work with each other and learn from each other. You are strongly encouraged to study and work with other class members.  You are also strongly encouraged to consult Dr. Comar outside of the class periods either during office hours or via e-mail at or text.

Academic Honesty:

The search for truth and the dissemination of knowledge are the central missions of a university. Benedictine University pursues these missions in an environment guided by our Roman Catholic tradition and our Benedictine heritage. Integrity and honesty are therefore expected of all members of the University community, including students, faculty members, administration, and staff. Actions such as cheating, plagiarism, collusion, fabrication, forgery, falsification, destruction, multiple submission, solicitation, and misrepresentation, are violations of these expectations and constitute unacceptable behavior in the University community. The penalties for such actions can range from a private verbal warning, all the way to expulsion from the University. The University's Academic Honesty Policy is available at , and students are expected to read it. Acts of any sort of academic dishonesty will not be tolerated.  All instances will be pursued.  The first case of any academic dishonesty will result in a grade of zero for the assignment.  A second case will result in failure of the course. Any incident of academic honesty on the final exam will result in failure of the course.

Your name should appear on all of your submissions of your work.  If collaboration is allowed, you must state with whom you have collaborated.  You are responsible for understanding any authorized collaboriation policies on specific assignments. You must also properly reference any other print, electronic, or human resource that you consult.

Electronic Devices Policy

One aspect of being a member of a community of scholars is to show respect for others by the way you behave. One way of showing respect for others in the educational community is to do your part to create or maintain an environment that is conducive to learning. That being said, allowing your cell phone to ring in class is completely inappropriate because it distracts your classmates and thus degrades their overall classroom experience. For the sake of your classmates, you are expected to turn off your cell phone or set it to mute/silence BEFORE you enter class-every class. Furthermore, if you use your cell phone in any manner during class (e.g. text messaging, games, etc.), you will be dismissed from class and will forfeit any points you might have earned in the remainder of the period. If you use your cell phone in any manner during a test or quiz, you will receive a zero for that test or quiz. (This policy also applies to pagers, iPODs, BlackBerrys, PDAs, Treos, MP3 players and all other electronic communication and/or data storage devices.)
