3 III. TEACHING AND LEARNING ACTIVITIES (TLA) COURSE TEACHING AND LEARNING ACTIVITIES Course Teaching and Learning Activities Expected contact hour Study Load (% of study) TLA1: Interactive Lectures and Discussions Interactive lectures will be provided by the lecturer to illustrate and reinforce basic concepts and knowledge of data communications and networks. Students are expected to have done pre-class reading and preparation and encouraged to share their views and experience actively in class discussions to deepen their learning. TLA2: In-Class Case Studies Case studies of network management, wireless networks configuration and network security will be discussed in class. Students are encouraged to participate in discussions and identify the key issues, sharing their opinions and solutions with their peers. These discussions will help students apply their concepts and knowledge to solve business problems. TLA3: Project Students will investigate how the latest network applications such as VoIP, Cloud Computing, and SOA etc applied in supporting business development. TLA4: Demonstration Live demonstrations of video, software and technologies will be done in class to show students how the technologies are applied in real world. TLA5: Guest Seminar A guest seminar will be conducted for selected topics. Students are required to attend the seminar, participate in discussions, and share their ideas with the guest based on the topics discussed. The guest seminar offer students opportunities to meet a professional practitioner and understand how he/she manages/applies networks system in his/her organization. TLA6: Laboratory Session Assignments Students are expected to follow the instructions to complete all the required software exercises. Case studies will be provided to assess if students can apply the skills and technique related software and technologies to solve problems. TLA7: Examination Final examinations test students knowledge of the topics covered in class and their ability to apply that knowledge. 36 hours 30% 6 hours 5% 6 hours 5% 6 hours 5% 2 hours 1.6% 6 hours 5% 3 hours 2.5% TLA8: Self Study 55 hours 45.9% 120 hours 100% Total (within hours)

4 IV. ASSESSMENT Assessment Methods Standards For Assessment Each student will be assessed by a combination of the group work (45%) and individual work (55%) Assessment Criteria and Marking Rubrics Business cases are used in this course to present a global view of the subject and to challenge student to use their subject relevant knowledge and judgment for effective business decision making in the context of telecommunications as a team. They will be expected to work in a group, analyse a case, and make a formal report of the case. Students are also required to submit a soft copy as well as a hard copy of the case report. Weight Aligned Course Learning Outcomes AT1: Case Analysis Grade for the presentation will depend on the ability of the team to deliver a professional and persuasive presentation that identifies the key issues related to the case. Grade for the case report will depend on the following: i. identification of major issues and problems in the case, ii. application of appropriate concepts to analyse the situation under study, and iii. a well thought-out and credible recommended course of action. An important aspect of the course is to complete a project that allows student to work as a team and enables them to carry out in-depth research on a chosen topic. They will be asked to work in small groups. There will be a project presentation and a report due at the end of the semester. All members of the group need to participate equally in all group activities. Any problems with group dynamics need to be resolved as soon as possible. 15% CLO1, CLO2 AT2: Project and Presentation In the project students are expected to review latest research on a stateof-the-art technology that is related to the theme of this class and present recommendations on the usability, impact, and relationship of this technological development to the telecommunications practices of modern businesses. 25% CLO1, CLO3, CLO7, CLO9 AT3: Assignments (Individual) Grade for the project will depend on the following: i. innovativeness of the project, ii. completeness of coverage of the topic in the project, iii. relevance of your project to the business world, and iv. ability to work as a team. Assignments are an integral part of this course because they test students knowledge of relevant theories and the ability to apply that knowledge for solving practical telecommunication network design problems. Assignments will include mini case research and analysis. All assignments are to be individual submissions. 20% CLO2, CLO4, CLO8 AT4: Class Participation (Individual) Grade for the assignments will depend on the correctness of the answers to problems, clarity of presentation, and completeness of your solutions. Student participation will be measured to evaluate their enthusiasm and activeness in class works, and discussion both in classroom. 10% CLO4, CLO6, CLO

5 AT5: End-of-Term Examination (Individual) The exam will be closed book and closed notes and it will be organized inclass. The exam will be comprehensive in nature and it will involve multiple choice questions, short answer type questions, problem solving questions, situational decision making questions or any combination of the above. Grade for the exam will depend on the ability of the student to express his/her understanding of the theories of data and voice communication, apply the learned theories for solving problems related to design of telecommunication networks, and clarity and correctness of his/her writing. 30% Total 100% CLO1, CLO2, CLO4, CLO5, CLO8 V. Course Final Grade A student s final grade for the course will be assigned according to the cumulative score that s/he has obtained from all of the assessment tasks: o Course Final Grade = Cumulative score of all assessment tasks obtained (100%) o Course Final Grade = Case Analysis and Presentation (20%) + Project and Presentation (25%) + Assignments (Individual) (15 %) + Class Participation (Individual) (10%) + End-of-Term Examination (30%) The conversion of the accumulative score to the course final grade is summarized below: Course Final Grade Cumulative Score of all Assessment Tasks Obtained A+, A, A- 100% - 80% B+, B, B % C+, C, C- 69% - 60% D+, D 59% - 50% F <50% Course Grade Descriptors: A+, A, A- B+, B, B- C+, C, C- D+, D F Strong evidence of superb ability to fulfill the intended learning outcomes of the course at all levels of learning: describe, apply, evaluate and synthesis.

COURSE POLICIES University of Hong Kong is a high-education institution with integrity. Hence, the university

15 takes the issue of academic integrity very seriously. The University Regulations on academic dishonesty will be strictly enforced! Please check the University Statement on plagiarism on the web: Academic dishonesty is behavior in which a deliberately fraudulent misrepresentation is employed in an attempt to gain undeserved intellectual credit, either for oneself or another. It includes, but is not necessarily limited to, the following types of cases: Plagiarism - The representation of someone else's ideas as if they are one s own. Where the arguments, data, designs, etc., of someone else are being used in a paper, report, oral presentation, or similar academic project, this fact must be made explicitly clear by citing the appropriate references. The references must fully indicate the extent to which any parts of the project are not one's own work. Paraphrasing of someone else's ideas is still using someone else's ideas, and must be acknowledged. Unauthorized Collaboration on Out-of-Class Projects - The representation of work as solely one's own when in fact it is the result of a joint effort. Cheating on In-Class Exams - The covert gathering of information from other students, the use of unauthorized notes, unauthorized aids, etc. Unauthorized Advance Access to an Exam - The representation of materials prepared at leisure, as a result of unauthorized advance access (however obtained), as if it were prepared under the rigors of the exam setting. This misrepresentation is dishonest in itself even if there are not compounding factors, such as unauthorized uses of books or notes. As this course involves some technical approach in network and telecommunication, attendance is very important to those who did not have strong technical background students. XII. Additional Course Information Penalty for late assignments - 20 marks of the final mark will be deducted
