Course Texts
eCore has explored cost-reducing options for students and currently offers open-source texts
for this course. The term open implies information or technology that is shared freely without
copyright restrictions. NOTE: These materials are collected from multiple higher education
resources, including sources that are printed in British-English. The spelling of words and
grammar may differ to American-English. Although extremely rare, some material may have
minor typos. We strongly encourage you to report these mistakes using the Student Change
Request form in the Course Resources module.
The open texts for this course allow students to read, download, and/or print the book at no
cost. The assigned chapters are embedded in each of the seven units that make up the course.

Attendance, Participation, and Time Commitment
“Attendance” and participation are required. You will be expected to participate in ongoing
discussions of the lesson topics and to interact with other students and your instructor regularly.
It is expected that you will demonstrate a positive attitude and courtesy toward other
participants in the discussion and observe good discussion netiquette. Be sure to read and
observe the following procedures:
●
●
You are a guest in the instructor’s classroom, so be sure to observe the class rules.
Practice manners and civility, and be polite and respectful of your instructor and
●
●
●
classmates in all your communication.
Respect your instructor, and be on time in your work submissions.
Keep your instructor informed of your status.
Address your instructor as Professor or Doctor.
●
●
Use correct grammar and punctuation in all your communication (‘Dear Professor xxx’
not ‘Hey’).
Accept your instructor’s feedback and learn from it.
In the online environment, problems associated with power outages, networks being down, and
ISP troubles inevitably result in legitimate reasons for delays, however, you should still be
prepared to deliver your work by the stated deadlines. If you have a problem, let your instructor
know as soon as possible. The student who repeatedly turns in late work will be subject to
penalties.
Time Commitment
Taking an online course is not easier or faster. On the contrary, it will take as much time as
taking a face-to-face class or more. If you normally go to class 3 hours per week per course, you
will need to devote that same amount of time to your online course. In addition to online time,
you should spend time studying and working with course materials several hours per week
offline. It will be helpful to set aside regular study time when you can work uninterrupted.
Offline time could be spent in composing messages to post online, reading, studying, and
working homework problems.
The amount of time it will take you to complete the work for the course will depend on many
factors, which will vary with each individual. Students can expect to spend anywhere from 8 – 15
hours per week on this course. Consult the course Calendar and your instructor to be sure you
are on schedule, keeping up with the material and taking quizzes on time.
As a general rule, in this course you will be expected to:
●
●
●
●
Log in regularly to check messages from your instructor and other students.
Check the Calendar for announcements from your instructor.
Read and study online materials and work all assigned problems for each lesson.
Complete all course work and assignments in the time allowed.
Conduct
You are expected to refrain from profanity, crudeness, and slurs of any kind. In other words, you
are expected to behave and treat your fellow students and instructor fairly, just as you would in
the traditional classroom.
Just as you would listen to others speak in the classroom, you are expected to read and respond
politely and thoughtfully to others in the online course. You are expected to refrain from crude
or unbecoming comments and be supportive of the class. Proper conduct applies to all forms of
communication in the course.
Late Policy

Grade Scale
Grades are based on student performance and capability. Simply turning in all the assignments
does not guarantee that the student will receive a “good grade.” To receive a higher grade, a
student must demonstrate proficiency in the material. For different students, gaining that
proficiency requires different levels of work, because not all students walk into the class with the
same aptitude for the course content. The standards for the respective grades are as follows:
A: 90-100%
B: 80-89%
C: 70-79%
D: 60-69%
F: 0-59%
Grade Turnaround: All assignments and assessments will be graded within one week’s time.
The instructor will provide comments along with the grade as necessary for feedback.
Expectations and Standards
A – To achieve this grade you must display superior performance in his/her course work. This
includes demonstrating the ability to process and comprehend complex ideas, and to be able to
convey those ideas to others in a clear, intelligent manner. An “A” student will go beyond simple
requirements and seek to excel in his/her preparation for and presentation of assigned work.
He/she will demonstrate excellence in communication skills and the ability to contextualize
material.
B – To achieve this grade you need to display above-average performance in your course work,
including demonstrating the ability to process and comprehend complex ideas, while being able
to convey those ideas in a clear, intelligent manner. As a “B” student you will also go beyond
minimum requirements in terms of preparation and presentation of assigned work. You will
demonstrate above-average communication skills and ability to contextualize material.
C – For this grade, you must meet the minimum requirements for the course, displaying
adequate performance in his/her course work, and adequately demonstrate the ability to
comprehend complex ideas, while also being able to convey those ideas in a like manner. A “C”
student demonstrates competence in terms of preparation and presentation of assigned work.
You will demonstrate adequate communication skills and the ability to contextualize materials.
D – A student receiving this grade is performing below the minimum requirements for the
course. This could include failure to complete or turn in assignments on a timely basis, or failure
to adequately demonstrate the ability to comprehend or convey complex ideas. A “D” indicates
that your performance is below the average in terms of preparation and presentation of
assigned work. You may not be demonstrating adequate communication skills or the ability to
contextualize materials.
F – If you receive an F, you have failed to meet the requirements of the course, including failure
to complete or turn in assignments, or failure to demonstrate the ability to comprehend or
convey complex ideas. An “F” student has not performed in a manner satisfactory to the
standards of the class.
Academic Honesty
(Acknowledgement is hereby given to Georgia State University on whose policy this is based).
Violation of the Academic Honesty Policy can result in failure of the assignment, failure of the
course, and/or further consequences form the student’s home institution. Ignorance of this
policy is not an excuse or a means to repeal a charge of academic dishonesty.
As members of the academic community, all students are expected to recognize and uphold
standards of intellectual and academic integrity. The University System of Georgia assumes as a
basic and minimum standard of conduct in academic matters that students be honest and that
they submit for credit only the products of their own efforts. Both the ideals of scholarship and
the need for fairness require that all dishonest work be rejected as a basis for academic credit.
They also require that students refrain from any and all forms of dishonorable or unethical
conduct related to their academic work.
In an effort to foster an environment of academic integrity and to prevent academic dishonesty,
students are expected to discuss with faculty the expectations regarding course assignments
and standards of conduct. In addition, students are encouraged to discuss freely with faculty,
academic advisers, and other members of the academic community any questions pertaining to
the provisions of this policy.

student may or may not pass the course as long as they take at least one exam
other words, the zero received on the missed exam will lower the average grad
perhaps below the passing mark.
