Core Assessment:
All Park University courses must include a core assessment tool that measures the degree to which students learn the course's learning outcomes. School policy dictates that a student's performance on the core assessment tool must count for at least 20% of the student's total course grade. For this course, the tool consists of the final exam. Therefore, the final exam must count for at least 20% of the student's total course grade. School policy dictates that the core assessment tool must cover at least 75% of a course's learning outcomes. To ensure compliance, all CS 365 instructors are required to give the same final exam. See the attached final exam artifact and artifact solution. To prevent cheating, students are strictly forbidden from keeping the final exam, the solutions, or copies of either.

The ICS Program Coordinator will analyze core assessment results for a sampling of all ICS courses offered. In analyzing the results, the ICS Program Coordinator will grade the exams using the (very specific) grading criteria shown on the exam solution. The final grade is in the form of a percentage where the percentages equate to the following levels of success:

Exceeds expectations

Meets expectations

Does not meet expectations

No evidence

≥ 85%

65% to 84%

< 65%

No exam graded.

The ICS Program Coordinator will use the core assessment scores to compare results across all instructional modalities.

For this course, the assessment is based on a final exam. There will be 4 questions in each of the 8 categories, i.e. Synthesis, Analysis,… etc. Thus, there will be 32 questions total in the final exam. Furthermore, all 4 questions for each category should cover all 4 learning outcomes.



You will be able to track your average exactly throughout the course. The grading scale is as follows: A = 90%-100%; B = 80%-89%; C = 70%-79%; D = 60%-69%; F = 0-59%. You will know in advance the standards for each assignment. My goal is to give you prompt, clear, and useful feedback to help you to succeed in this class. Each student is responsible for:

  • Completing Weekly Reading assignments
  • Completing Weekly Discussions
  • Completing Weekly Homework assignments
  • Completing Weekly Java Applet Simulation assignments
  • Completing Weekly Quizzes
  • Completing a Final Examination. This step is essential!
  • Completing a Online Survey of Student Opinion of Teaching

Reading Assignments:

Students will be expected to read the assigned chapters in the textbook and the lectures. The Online Discussions, Homework Assignments, Quizzes and Final Proctored Examination assume you have read the assigned readings.

Class Participation (Online Discussions):

Students should visit the conference area at least three times each week or a minimum three hours per week.

Homework and Java Applet Simulation Assignments & Quizzes

All assignments and quizzes should be completed on or before Sunday 11:59 pm Central time. Homework must be done independently. Students will place completed assignments in the dropbox. Do not post answers to quizzes or assignments in the discussion threads.

Submission of Late Work:

All assignments and quizzes are due 11:59 pm Central Time on Sunday of the academic week. There will be 20% penalty for each day that an assignment is late. Students are not allowed to take a quiz that is scheduled beyond its due date.

Proctored Examination:

Final Examination - An examination will be taken in person during the 8th (or 16th) week of instruction at one of the Park University sites around the country or at an alternative location approved by the University where Park University sites are not available. It will be the responsibility of the student to arrange for a proctor, by the 6th week, who will be accepted and approved by the instructor. Guidelines for selecting an acceptable proctor can be found at the Park University website. For proctored examinations, photo identification is required at the time of the test. A proctor request form will be made available to you during the first week of class so that you can send your requested proctor to me for approval. Failure to take a final proctored exam (or submit your final project for some online graduate courses) will result in an automatic "F" grade. Some graduate courses may not require a proctored final examination.

Grade Distribution:

Assignment Points % of Grade (roughly)
Discussion Participation 84 12
Quiz 210 30
Homework 147 20
Java Applet Simulation 108 15
Final Exam 160 23
Total 709 100

Course Grading Scale:

This subsection should list the grading scale and weighting for all of the graded work during a course. The grading scale must use the following scale below, and point totals for each letter grade must be included (see example below). Example -

A = 90-100% (or 638 points or higher)
B = 80-89% (or 567 to 637 points)
C = 70-79% (or 496 to 566 points)
D = 60-69% (or 425 to 495 points)
F = < 60% (424 or fewer points)

Late Submission of Course Materials:
