Introduction

Strategies for Classroom Management in a Computer Lab

Before going to the computer lab.

1. Check to make sure that all students accounts are active; be aware of any students who

may have restricted access for some reason.2. Know the process that students use to log in to the network.3. Remind students of their responsibilities established through the schools Acceptable Use

Policy.

4. Establish any additional classroom rules for your class when using the computer lab.5. Define and identify inappropriate behavior and use of equipment before and duringlab

time.

6. Identify consequences for violating any rules and enforce them.7. Test the lesson ahead of time to anticipate questions and problems.If possible, have

students meet in their regular classroom for attendance and last-minute instructions

before going to the computer lab.

8. Assign students to specific computers, possibly the same computer in the lab throughoutthe year (unless special groups are working together for a project).

In the lab.

1. Ask students to deposit books, backpacks, etc. away from the workstations and take onlywhat they will use to work areas.

2. Tell students to check equipment at the beginning of class and to report any damaged or

missing pieces right away so that they are not blamed for lost equipment or vandalism.3. Build in extra time for network/software/Internet instruction, especially for first visits to

the lab.

4. Give students a checklist of tasks/work for the period, along with a timeline.5. Move around the room to offer additional instruction/direction, and to monitor student

work, but do not stay too long at any one workstation

6. Report, in writing, all problems to the technology staff (written notes, email, repair

forms).Remind students to push in chairs, clean work areas, and take personal belongingswhen leaving the lab.

Strategies for increased student productivity in the computer lab.

1. If available, use a projection system for instruction. Students will be able to see theinstructors computer and follow directions visually.

2. If instructions are not about a computer function, have students turn off their computermonitors and focus on the instructor while directions are given.

3. Use a rubric/scoring guide for lab work and give a grade. Students will be more directed

in what they do.4. Grade/check assignments or projects in stages (outline, rough draft, etc.) to make sure

students are progressing through their work.

The above ER diagram represents computer lab management system which keeps

the track of students accessing the lab and the time period for which they were in

the lab.

The lab administrator keeps check only authorized students are allowed in lab.

The student data is collected from their respective cards. and username and

password of computer is provided to them according to card no/ registration no..

Lab data is available to administrator and according to that data group of students

can use the labs.

Labs have their respective status and location stored which can tell the availability

of labs for make classes or maintenance purposes.

RELATIONAL DATABASE DESIGN

After coming up with an Entity-Relationship model to describe thelibrary system, we took advantage of the special relationships found inour design, and were able to condense the information to tables.This new design is a database that combines some entities andrelationships into common tables.

NORMALIZATION

As stated earlier, the tables in this database are in the Third NormalForm (3 NF.) In order to decompose the relationships into this form,we had to split Status table from the lab table. Each lab objecthas a status code, and each status code has an associated description.It would be redundant to store both codes and descriptions in thelab object, so we created a dedicated Status table with the code asthe primary key.The other tables were designed with optimization in mind. The Cardentity, for instance, was separated from the student entity to avoid a

functional dependency.q$%v|,t*
