Student Hardware Resources

Student access to computers is primarily concentrated in the computer labs. However, the technology lab is the only one with Internet access.

Discussion of the Plan

Networking

The computer network at WLVHS should be completed as quickly as possible if the school plans on using the computers as a means of educating students about the Internet. Currently, the technology lab and the Library are the only rooms connected to the network. Due to budget constraints, classrooms, offices, and the two other computer labs have not been connected.

Objective 1: Completion of the WLVHS Network

To complete the network setup at WLVHS, it is necessary to:

1. Connect the following offices, classrooms, and computer labs with appropriate ThinNet lines:

A diagram mapping the complete networking of WLVHS is shown on the following page:

Figure 2: Proposed Network



Recommendation - The work described here should be completed as soon as possible.

However, just finishing the wiring will not complete the network setup at WLVHS. Almost every office and classroom located on the WLVHS campus do not have computers. If they do have computers, they are either too old to be connected to the network or do not have the proper equipment needed for accessing the network.

Objective 2: Student Computer Labs On-line

At the present time, there is only one (1) computer lab with a network connection (technology lab) at WLVHS. This is not adequate for the current level of use by students for classroom assignments. There are two (2) additional computer labs that should be placed on the network. Only one of theses labs has computers with the necessary specifications needed for accessing the network. However, the lab only has twelve (12) Network Interface Cards (NIC), which are necessary for accessing the network and it should be determined by the Network Administrator which computers should receive the NICs. Some computers in each laboratory should be connected in order to support needs of the students at WLVHS.

Recommendation - All or a portion of the computers in the technology lab and in the new computer lab should be connected to the network as soon as possible. The Network Manager will need to purchase 43 NICs for each computer that is to be connected to the network at the approximate cost of $100 each. The computers that are too old to be effectively networked (seventeen 286s ,fourteen 386s) will need to be replaced or upgraded.

Objective 3: Classrooms On-line

In orders to achieve the most effective use of new classroom technology, classrooms, lecture halls, and laboratories need to be connected to the network. The computers can be used for classroom presentations that is using material from the Internet.

Recommendation - All laboratories and classrooms used for presentations should be connected to the network as soon as possible. This is discussed more thoroughly in the Future Issues section.

Additional Issues

This section identifies specific areas in which problems, new technology, or other concerns need to be addressed immediately. Longer range issues are addressed in the next section, Future Issues. Recommendations made in this section concern the following additional issues:


Additional Issues


Improper Use


Maintenance

Improper Use

The downloading of pornographic material, information, or software may be considered improper use by some individuals while others see it as a means of entertainment. Policies should protect the rights of all legitimate users while not limiting the rights of others.


Recommendation - Each individual accessing the Internet needs to be aware of what is considered improper use of computers. A policy regarding improper use of computers on campus should be given to all faculty, staff, and students along with their consequences.

Maintenance

Network Administrator(s) are required to maintain the network. They oversee all systems and functions of their local area network. The Network Administrator is in charge of creating new users, mapping drive letters, tracking disk space, fixing a failed server, and changing the Server Configuration.

Recommendation - Select Network Administrator(s). Make sure that more than just one individual is aware of what the Network Administrators responsibilities and duties are. If something happens to one person, there is second who knows the passwords and what to do. Also, if important information is stored on the system, it may be beneficial to invest in a tape-drive for backing up this information.

Future Issues

When planning for the future, major issues need be addressed. This section deals with issues that are major concerns and offers suggestions to help deal with those concerns.


CONCERNS


Training


Security


Budget


Funding


Expansion

Training

Many individuals know what the Internet is and what it is capable of doing. However, many do not know how to use it. Supplying West Las Vegas High School with the ability to access the Internet is not enough, many users tend to be inexperienced or lack the knowledge needed to properly and efficiently use the Internet.

Recommendations - 1) A budget for training needs to be obtained. Instructors can attend the five week Internet course offered at New Mexico Highlands University. By attending this course, instructors will learn how to properly and efficiently use the Internet and can then go back to WLVHS and teach others what they have learned in class and on their own or,

2) Highlands personnel involved with the NASA Outreach Network project will conduct a series of four training sessions for teachers and their selected students. This will provide extensive training both on the basics of Internet ­ how to use e­mail, telnet, ftp, gopher, mosaic and the other tools available on Internet ­ and on how to use the capabilities of Internet to promote learning.

Estimated Cost - The cost of this five week course is approximately $63.00 per person.

Security

With the increasing knowledge of technology many individuals find ways of breaking into other computers to access prohibited information. West Las Vegas High School instructors will need to protect information kept in their computer (exams, grades, homework, etc..) from students or other instructors capable of accessing that information.

Recommendation - West Las Vegas High School faculty/staff should have passwords to access their computers. When a computer is turned on it will first prompt the user for a password to get into the computer. If the password is correct, access is granted, however if it is incorrect, access in denied. That password should be know only known to the individual owning that particular system.

Budget

West Las Vegas High School administrators do not visualize adding more computers to their inventory in the near future due to budget constraints. Computers are not a primary concern although they should be. WLVHS needs to be brought up to date with the knowledge and technology of computers can offer.

Recommendation - In order to achieve the objectives identified in this document it is necessary to increase the expenditure required to purchase computers for the West Las Vegas High School.

Funding

Computers are no longer used primarily for businesses, they have become tools used for modern education. Education can be expanded by use of computers in classrooms, this becoming important to academics.

Recommendation - Apply for all grants possible and use money to purchase more computers for staff and students.


Expansion

West Las Vegas High School has visions of building a new school. With this new school administrators would like all rooms to have the ability to access the Internet.

Recommendation - All rooms and offices should be wired during the construction of the new building, it will be cheaper and easier to wire before construction is complete.

5 Year Plan

A five year plan has been developed to provide every classroom and office in the main building with the ability to access the Internet. Since the proposed cabling system wires all rooms that contain equipment capable of accessing the Internet, the five year plan concentrates on the remaining rooms. This plan can be completed by following Phase 2 and 3 described on pages 17-18 of the West Las Vegas Schools Technology Plan. In order to wire all offices and classrooms that were not considered when the proposed cabling system was developed, the following hardware will need to be purchased:

The hub will be mounted in the communications room and will provide service to the five 90C DECRepeaters. The four additional repeaters provide twenty-four ports and the ability to wire twenty-four rooms. All classrooms and offices can be wired using twenty-two ports, leaving two ports open. A future plan to cable every classroom and office is summarized in Table 7.

Conclusion

In conclusion, West Las Vegas High School needs to increase funding for computers and computer training. Funding is a key problem and can be accomplished by :

1. Applying for grants.

2. Seek outside funding for purchase of computers.

3. Use computer technology to improve academics.

4. Work with Highlands and NASA to implement the Outreach Network.

Computers, information, and networking involve large amounts of money, money that is currently not available in the budget at West Las Vegas High School. With out funding, teachers and students are being denied access to the Internet and its advantages:

1. Teaching problem­solving skills

2. Supporting group and individual research/exploration efforts by students.

3. Creating larger communities of scholars by allowing students to reach out

across the net to other students with similar interests.

4. Allowing teachers to get easy access to educational materials for the

classroom.

5. Providing access to information about colleges and universities.
