Inquiry Based Learning Unit Template                            1
Essential/Driving Question              (provide a central focus for student inquiry)

How would a team design a local area network (LAN) that best meets a client's needs?


Critical Questions
How can the client’s requirements for a LAN be determined?

How can the cost of the implementation be a prohibitive factor over a superior design?

Should an existing LAN be upgraded or replaced?

What are some of the potential roadblocks to successfully implementing a LAN design?

What standards for LAN design need to be met?

What questions should be asked of the client?


Unit Description          (write a brief description that encompasses all content and outcomes)

The team, composed of 3-4 students, will determine a client’s needs for a local area network

(LAN). The team will then complete the research required to design the LAN such that the

client’s needs are either met or exceeded. The team will then present their design to the

client. Each team member will be responsible for completing part of the design, as

determined by: the client’s needs, sound LAN design criteria, and the team members.

Documentation of the design is critical for successful completion of the unit. This

documentation can be presented in the form of a 3-ring binder with copies of their documents

with a CD/DVD containing electronic copies OR a Web site that contains copies of their

documents; however, the web site must include means for downloading electronic copies of

their files.



Entry Event (define how the problem will be introduced so that it provides authenticity)
A scenario will be introduced to the students (either by the instructor who is playing the role

of a client or by a representative from business/industry). During this introduction, the basic

considerations of the local area network (LAN) design will be discussed, a potential budget,


Inquiry Based Learning Unit Template                                                          2
points of contact from the client, as well as a preliminary timeline for project completion.

Methods of communication will be determined (e-mail will be required; any other method(s)

will be at the team’s and client’s discretion). This discussion will challenge the students to

ask critical questions regarding the importance of a stable LAN. The scenario will be limited

in scope to those found in small to medium sized business environments.

Sample Entry Event:

“Mr. Bigboss addresses the design team during their initial meeting. He presents them
with the initial design criteria for the much needed local area network for his company
which consists of approximately sixty employees in three locations spanning a distance
of 100 miles. The design must accommodate a bandwidth of 100 Mbps, with plans to
handle 1000 Mbps. The infrastructure must meet industry standards including a
wireless network capable of handling at least IEEE 802.11g and possibly 802.11n (if
budget permits). The existing computing hardware is mostly Windows XP Professional;
however, some Windows Vista Business installations are present as well as a couple
legacy stations running Windows 98 SE. Mr. Bigboss emphasizes the need to maintain
business continuity during the installation phase of the project and a need to offer
several employees the option to work from their homes. He provides several points of
contact for questions that the design team may have in the near future that include both
technical and non-technical employees and states that the design must be completed
within four weeks in order to begin the installation during a scheduled maintenance
downtime that affects most of the organization.”

Estimated Time (estimated time required to complete the unit)
Time to create the unit will vary greatly based on the size of the chosen organization. See
instructional consideration.

Groups

To maximize the learning process for each student, groups of three to four are encouraged. Each

Inquiry Based Learning Unit Template                                                         4
student’s knowledge is expected to grow at an accelerated rate in a team environment as opposed
to learning on their own. This occurs because each student can take advantage of the other
individual’s research, thoughts and interpretations. Students learn through collaboration.

Amount of Preparation Time Required for the Project

This project will span two academic quarters. It will begin during the last half of the winter
quarter and will end with a presentation by the group at the end of spring quarter. Over the
course of the prior summer and fall quarters, the material will prepare the students with
knowledge of local area networks (LANs) as well as how a LAN is integrated into a business/
organization’s critical functions. Each student should understand the role that a LAN plays in
helping the organization fulfill its business plan.

Outcomes

The intended outcomes from this unit include:

        Understanding the role of Information Technology Services in today’s world
        Interacting with professionals in their chosen field
        Understand how an organization operates by using a LAN
        Learning to write a lengthy paper incorporating what is learned in the classroom as it
        applies to the real world
        Applying critical thinking skills by conducting proper evaluations, developing
        appropriate understanding levels and making recommendations regarding hardware,
        software and human resources


Student Knowledge/Skill Level               (student skill level is listed and consistent with unit content)


Experienced: This should not be the first time the student has discussed the details of a local
area network (LAN), including the hardware requirements, the logical design, the physical
design, and the costs associated with a LAN.

Inquiry Based Learning Unit Template                                                             5
Prerequisites (what, skills, knowledge, materials must students have to participate in this unit)
Students should have experience with selecting equipment that is used on a local area
network (LAN). They should have already configured some of the equipment that will be used
such as switches and routers. They should have an understanding of LAN standards as well as
the types of cabling that may be used to connect LAN devices.

Students need good writing skills in order to prepare a proposed LAN design. They should also
have good communication skills in order to convey their design concepts to the client (as well
as gather design criteria from the client).

Students should have basic accounting principles for budget planning purposes and
determining the total cost of installation.




Pre-Assessment (how will you find out what they already know)
To determine pre-existing knowledge, each team should develop a list of design requirements
for a local area network (LAN). Each team will share their list with the rest of the class and
discuss the pros and cons. This should lead to a comprehensive list of design requirements.
Students can develop their own criteria for evaluating a LAN design, e.g., expandability,
functionality, manageability, security, etc…


Materials Needed (list materials needed to implement this unit)
        A computer that is connected to the Internet (for research). This computer should
        have appropriate software for documenting the design including a word processing
        application, a spreadsheet application, and some application for creating either a
        presentation and/or networking diagrams (e.g., Microsoft Visio, PowerPoint, etc…)

        Each team member should have a 3-ring binder that can be used to store all of their
        information (preferably with dividers to keep the information organized, such as
        “Client Notes”, “Design Ideas”, “Hardware Specs”, etc…)


Facilities (list facilities requirements)
        A place where the team can meet to brainstorm and research their design criteria.

        A place where the team can meet with the client to discuss the design requirements
        and their progress as the need arises.


Business and Industry Resources              (list businesses/industries and contact persons)

Local businesses that design and install LANs may be willing to provide free advice and/or
guidance to the team(s). These businesses not only understand the national standards but
may also have a feel for the local customs/traditions related to network design (e.g., EIA-TIA
Inquiry Based Learning Unit Template                                                        6
568-B terminations rather than EIA-TIA 568-A.

Equipment Manufacturers/Vendors/Distributors may provide varying degrees of detail
regarding the installation and configuration of networking hardware, software, etc…

The following link is an example of such a resource
http://www.linksysbycisco.com/static/au/Learning-Center/



Other Local Assets (list any OTHER local resources that are available as resources for this unit)
Many local businesses may allow the teams to visit their facilities and view their existing local
area networks (LANs) in order to gain appreciation for the scope of the project.




Print/Electronic Resources             (list any such resources that you will make available to students)

Communication Devices:
     Computers with Internet access and a productivity suite (such as Microsoft Office or
     OpenOffice) are essential
     Additional software such as Microsoft Visio, Cisco Network Designer, etc. would be
     helpful for creating some of the design documentation.

Internet Sites:
       There are many Web-based sites relating to network design such as:

        http://www.cisco.com/warp/public/146/kits/cat_011800/guide.pdf
        http://www.cisco.com/en/US/docs/internetworking/design/guide/nd2012.html
        http://etidweb.tamu.edu/cdrom3/START.PDF



Teacher Tips (list any tips that you believe will enhance this learning unit)
Even though this project is designed for the experienced, students may have difficulty “wading”
through the plethora of information available on local area network design and hardware choices.
To assist them, the instructor may suggest a few specific Web sites and/or companies from which
to gather their initial data.

Each team will give a 15-20 minute presentation on their final design that will include a
speaking part by each student and must include graphics (such as a PowerPoint presentation, a
spreadsheet with graphs, Visio diagram, etc…).

This is a problem-solving project. Students are expected to do a great deal of research and
teamwork. Monitor teams closely to make sure all students are participating and teams are
staying on-task.

If the instructor can help locate businesses at which the teams can view local area networks,
either formally (such as a field trip) or informally (individuals, or each team)
