Assignment Overview

Discussions

You will be expected to actively participate in the discussion each week throughout the course. While actively reading the textbook and Content in our online course are the foundation for the mathematical knowledge, additional learning happens through our discussion of the concepts and the ideas behind the calculations on the discussion board.

Each week you will choose one discussion question from Content to post in the Discussion area of our course. Effective posts will lead the reader through your thought processes and explain key ideas or where difficulties might arise. The goal is to look for patterns in the problems, provide thoughtful analysis and synthesis, and solve problems involving multiple concepts.  This will help you generalize from the particular problems to rules that apply in similar situations.

You will also respond to at least one of your classmates’ posts.  Your response should provide more than “Good post” or “I got the same answer.”  Ask questions about areas that are confusing to you or where you would like to see more details about the process.  You could also provide an alternate conclusion or solution process.

Your initial posting should be posted by Friday; responses to classmates should be posted by Sunday each week.  The expectations and grading rubric for discussions are outlined in more detail in the course Content area.


MyLabsPlus

Guided Notebook

There is no traditional print textbook or ebook with this course. The 300 page Guided Notebook becomes your print textbook with your help. It is recommended that you fill it out as you are completing the Interactive Assignments in MLP. Completion of the Notebook will help reinforce key concepts and the Notebook will be a great review resource for you. You will not be turning in the Notebook for grading.

Interactive Assignments

Interactive assignments in MyLabsPlus consist of readings and videos that introduce course concepts. The assignments include questions that test your comprehension. You can check each answer on the questions and rework them to improve your score. You must earn at least 70% on the interactive assignment in order to access the associated homework set.  However, scores on the interactive assignments are not included in your course grade.

Homework

Each week you will have access to homework problems in MLP from each section covered. You will gain access to these only after successfully earning 70% or higher on the interactive assignment.  You may rework each interactive problem and each homework assignment until its due date.  You may continue to work problems for additional practice after the due date; however, homework completed or redone after the due date will incur a 10% late penalty.

MyLabsPlus provides tools to assist you with the homework such as Show me an Example or Help Me Solve It.  If you use these tools, you will have to complete a similar problem without using the tools in order to receive credit for the problem.  You may rework each homework exercise until you get it correct by selecting “similar exercise” at the bottom of the screen.  It is recommended that you practice until you feel very comfortable with the problems. 

Note:  Homework grades will not be transferred until the end of the session.  Your final score at the end of the session is the one that will be reported in the gradebook and is recorded as a percentage of the 200 points possible for homework assignments.    



Quizzes

There are quizzes in Weeks 1-3 and 5-7 are each worth 25 points. Quizzes are timed (60 minutes), multiple choice, and computer graded.  You will have 5 attempts on each quiz during the quiz period (with the highest score recorded), so use each attempt to improve your understanding of the concepts. The quizzes in Weeks 4 and 8 are for practice only and do not count toward your final grade. 


Exams

There will be a Midterm exam covering materials presented in weeks 1-3. The Final Exam is comprehensive, covering materials presented in the entire course. Both exams will be available in D2L, and must be taken in a proctored environment.

There will be an optional Midterm Exam Review Quiz and a Final Exam Review Quiz. You may take them an unlimited number of times to practice for the actual midterm and final exams.
