Exams and practice quizzes

There will be a quiz on each of the following dates. Each quiz will be given on Canvas. You can start each quiz from 8:00am to 10:00pm on the date of the quiz. You will have 60 minutes for quizzes 1, 3 and 4, and 70 minutes for quiz 2.

  1. Wednesday, September 22
  2. Friday, October 15
  3. Friday, November 5
  4. Monday, November 29

Final exam

The final exam will be administered in Canvas. You will have 150 minutes to complete it. The times are as follows.

Practice quizzes

There are two practice quizzes for every quiz. Practice quizzes are available in Canvas. There is no time limit for practice quizzes, but there is a due date. You can attempt each practice quiz any number of times up to the due date. The practice quizzes are due on the following dates.

Practice quiz Due date
Practice quiz 1, part (a) W. 9/8
Practice quiz 1, part (b) F. 9/17
Practice quiz 2, part (a) W. 9/29
Practice quiz 2, part (b) W. 10/6
Practice quiz 3, part (a) F. 10/22
Practice quiz 3, part (b) F. 10/29
Practice quiz 4, part (a) F. 11/12
Practice quiz 4, part (b) F. 11/19

Even though the practice quizzes do not count directly toward your grade, they do count indirectly. You will learn more if you try to answer questions before being shown the solutions. Work the practice quizzes.

Grading

Grades will be computed as follows.

Grading
4 quizzes 60%
A comprehensive final exam 30%
ZyBooks participation and challenge activities 10%

All quizzes have the same weight. See Canvas for Zybooks assignments. You must have the ZyBooks text to do the participation and challenge activities.

Tentative cutoffs for grades will be as follows. These cutoffs will not be raised.

Grade cutoffs
A 93% B+ 87% C+ 76% D+ 64%
A– 90% B 83% C 72% D 60%
    B– 80% C– 68% D– 56%

Attendance policy

You are expected to attend class, except when you are experiencing symptoms of a communical disease such as COVID-19. If you do not attend class, you will be expected to get all information that was covered in class from another source. Students who do not attend class almost always do poorly in this class.

Office hours

Office hours will take place in my office at the following times.

MW 1:00–1:50pm
MW 3:00–3:50pm
or by appointment

Students are required to wear a mask covering their mouth and nose while in my office for office hours.

Tutoring

A tutor, Lynn Abu Samhan, is available online. Her office hours are as follows.

TTh 9:00am–10:30am
TTh 5:00pm–7:00pm

To speak with the tutor online using Webex during the listed times, open https://ecu.webex.com/meet/abusamhanl21 in a browser.

Mask requirement and COVID-19 issues

As stated in ECU's Community Expectations, by working together, we can keep Pirate Nation safe for a successful Fall 2021 semester. Therefore, we will be observing the following class policies related to your health and safety:

Continuity of instruction

In the case of localized outbreaks affecting our classroom identified by health officials, we will transition to online delivery for up to two weeks for your safety. Health officials will closely monitor conditions and may need to contact you by phone to help them monitor public health conditions. Please ensure your phone number is up to date in PiratePort. After this period of up to two weeks, we will resume on-campus in-class activities. The temporary move to online course delivery will not affect the due dates for quizzes or other material except as explicitly communicated to you by the instructor.

I will post all necessary course materials on Canvas. Please communicate with me by email. It is recommended you save on your computer and/or print a copy of the syllabus, assignment schedule, and other important course material.

If it becomes necessary to move this course online temporarily, I will hold office hours using Cisco Webex Meetings. To attend online office hours during the listed times, log into https://ecu.webex.com/meet/abrahamsonk. You should be allowed to join the meeting automatically. If you have trouble, please send me an email.

Anyone can join at any time during the listed ofice-hour times. If you join while someone else is talking to me, please remain quiet until the previous student is done, unless you want to join in on the same topic. If you need to discuss something private, please set up a meeting with me by email.

You can find whiteboard controls on the screen. To type text, click on Tt, then click on a position on the whiteboard and type. To draw, click on the pencil tool and draw using a mouse. You might need to select a color using the lower square in the tool bar. You might need to change from the pen tool to the pencil tool by clicking on the tool and selecting pencil.

Computer and internet connectivity requirement

You will need to have a computer and internet connectivity to work the practice quizzes, which are on Canvas. In the event that the class is moved temporarily online, you will also need a computer and internet activity to access additional course material.

Recommendations for success

  1. Attend class. Arrive on time.

  2. Do not bring distractions to class. If you read your email, listen to music, send and receive text messages or engage in other distracting activities during class, you will get very little out of class. That will show up in your grade.

  3. Ask questions in class. If you do not understand something, ask a question about it.

  4. Ask questions outside of class. Use office hours or email.

    For email, please use a subject indicating that you are asking a question for CSCI 4602, and always include your name in your email. Please send email to the address listed on the first page of this syllabus.

    Do not expect immediate answers. Give yourself time to get answers. If you have not received a reply for a few days, please resend your email.

  5. Do the practice quizzes. That will help you to do well on the real quizzes.

  6. Schedule time to work outside of class.

  7. Repetition is the key to learning. Read relevant sections of the texts twice. Take a break (a whole day or longer) in between. Later in the term, go back over your notes and the textbooks that you looked at earlier in the term. Try doing the ZyBooks exercises again. You will learn much more that way.

  8. Get adequate sleep. Sleep is important both before and after you learn new concepts. Sleep before enables you to concentrate and think clearly, and sleep afterwards is critical for moving new information into permanent memory.

Students with disabilities

East Carolina University seeks to comply fully with the Americans with Disabilities Act (ADA). Reasonable accommodations will be made for students with verifiable disabilities. In order to take advantage of available accommodations, students must be registered with the Department for Disability Support Services located in Slay 138, 252-737-1016. See Accommodation Information & Processes.

Additional DSS student resources can be found at: https://accessibility.ecu.edu/students/.

Weather emergencies

In the event of a weather emergency, information about ECU can be obtained through the following sources:

ECU emergency notices http://www.ecu.edu/alert
ECU emergency information hotline 252-328-0062

Student conduct

Smoking is not permitted in classrooms. Please turn off telephones while in class.

Students are expected to abide by the university's Student Honor Code. Students who copy other students' work, or who allow their work to be copied, or who copy their work from other sources, such as the internet, will receive no credit.
