All students should carefully and thoroughly read the section entitled Academic Regulations and Procedures in the Brooklyn College Undergraduate or Graduate Bulletin for a complete listing of academic regulations of the College.

Academic Integrity

The faculty and administration of Brooklyn College support an environment free from cheating and plagiarism. Each student is responsible for being aware of what constitutes cheating and plagiarism and for avoiding both. The complete text of the CUNY Academic Integrity Policy and the Brooklyn College procedure for policy implementation can be found at . If a faculty member suspects a violation of academic integrity and, upon investigation, confirms that violation, or if the student admits the violation, the instructor shall report the violation to the College.

Student Disability Services

Consideration of Religious Observance

New York State Education Law (Title I, Article 5, Section 224-a) requires that the College

makes available to each student who is absent from school, because of his [or her] religious beliefs, an equivalent opportunity to make up any examination, study or work requirements which he [or she] may have missed because of such absence on any particular day or days.

If you are unable to attend classes or take examinations, the instructor is happy to accommodate you as permitted by semester schedule and other constraints there may be; however, it is recommended that you make arrangement with the instructor in advance. You may also contact Division of Student Affairs , if you have questions about accommodations for religious observance.

Policy and Software for Online Exam Proctoring

CUNY is procuring online proctoring software and is likely to conclude the procurement process and to deploy the software for use in CUNY classes on or before midterm season, i.e., late September to mid-October. A design objective of online proctoring software is to improve online exam security. To learn how it may affect you, you should take a look at some online proctoring software, such as, Respondus Monitor and Proctortrack.

In addition, there are required in-class exercises and discussion. For the in-class exercises and discussions, see the section of Assignments and Examinations for details.

Late Attendance

Students should join the online class meetings on time. A late attendance may be recorded as absence from the class.

Assignments and Examinations

Pre-lecture Assignments

The instructor assigns self-study assignments before each week's class meetings. These exercises are to help students learn the material discussed in the lecture during each class meeting.

Students should expect 14 Pre-lecture Assignments, generally, 1 per week.

In-Class Assignments

During an online class meeting, students complete activities related to the pre-lecture assignments or the lecture individually or in a pre-arranged group.

Students should expect 14 In-Class Assignments, generally, 1 per lecture.

Online Quizzes

There will be a few quizzes. Quizzes are online on [CUNY Blackboard]( All quizzes are individual assignments.

Students should expect 7 online quizzes generally, 1 every 2 weeks.

Programming and Laboratory Assignments

In general, the instructor assign programming or some hands-on assignments every 2 - 3 weeks. These are for students to experiment with network tools, protocols, and systems, and often require students to write programs.

Students should expect 4 of these assignments, generally, 1 every 3-4 weeks.

Projects and Presentations

The instructor assigns projects or research paper study and presentation assignments for selected major areas of study. These assignments are group assignments. These assignments are to provide students with sufficient practice and ample exploration to master the knowledge and skills pertinent to the area, and learn to collaborate in a team setting.

For each of these group assignemnts, the instructor will place each student randomly in a team of 3-5 students.

To grade these assignments, the instructor considers the quality of the group work and individual contributions. The students shall provide a peer evaluation. The instructor will provide an evaluation on the quality of the projects. Both of the student peer evaluations and the instructor’s evaluations will be used in the student’s final grade calculation. A student’s may receive a lower grade than the project quality grade if the student makes far few contributions than her or his team members. In an extreme case, a student who does not make any contribution to the project may receive no points on a group assignment as evidenced by the peer evaluation and the others (such as, Github commit logs).

Students should expect 3 of these group assignments, generally, 1 every 3-4 weeks.

Midterm and Final Examinations

Tips for Online Learning Success

The College designates this class as a Synchronous Online class in this semester. Below are some tips to help us succeed in this class.

Access to the Internet and Information Technology

It is essential that you have access to Broadband Internet, and to a computer with Web camera and microphone, minimally 8 GB RAM and 100 GB disk space and with the cability to run Oracle VM VirtualBox.

Be aware that the College and the University have made resources available to aid students. For instance, the College has established the Device Loan Program for Students and the University has a Virtual Desktop service In addition, the College maintains a Student Resources and Updates that documents services that students can leverage on for success. For instance, it describes the steps to obtain free Internet services from Charter Communications and Altice USA for students to take online classes.

Work Hours

You will need to devote at least 12 to 16 hours per week to the required lecture, reading, programming, experimenting, writing, and reasoning. Please devise a schedule (e.g., 2.5 to 3 hours per day, 5 days a week) and keep to it.

Online Lecture Participation

The online lectures are crucial. Although the instructor records lectures, you may not have as a good experience watching the recordings as you would in person in the online lectures. However, if you are only passively watching the lecture, you can quickly lose concentration. It is important to participate in the class actively, such as, participating in polling, answering your classmates’ questions, answering the instructor’s questions, and asking questions.

Group and Peer Learning

Peer groups can be effective and beneficial to learning. You should leverage on the groups to which the instructor assigns to, or establish a group of your own, and actively discuss the relevant class topics with the group.

Video Conferencing Tools

Video conferencing tools, such as, Blackboard Collaborate Ultra has particularly useful features, such as, sharing screens and sharing files. You should master the tools and communicate effectively with your classmates and with the instructor.

The Brooklyn College Learning Center

Don’t forget that Brooklyn College has a Learning Center that is committed to help students succeed. One essential service that the learning center provides is the tutoring service. Visit the learning center online for more information.

The Brooklyn College Student Support Services

The Division of Student Affairs oversees a wide range of services among which you may find some useful. Visit the student support services online for more information.
