BACKGROUND OF THE STUDYNowadays, the way many people interact with each other has changed because

of technology. First of all, absolute advantage is that technology makes the worldmove faster. To support, speed of daily business interactions increasing all thetime. There are many ways in which how technology is changing educating from pre-school to College, the education trend has now changed. Communications and deliveryof the education has become so advanced. Right from the primary school grades to theheight of graduate school, technology can be used as a powerful tool for education.Teachers, and students should take advantage of this.

Grading System is a very important aspect of a schools operation and goals.The student are graded to accurately compute the grades of the students using theircalculators, whether an ordinary of scientific type.

Grading System will help to improve to make faster and easier the manualgrading system in every school in many ways such as in computing and analyzing theperformance, talent and skills of students. It is the important record to keep evenfor the longest time for the referral and credentials of the student to enter theirnext level of attaining their goals. It is the tract record that recognizes of onestudent, this maybe use for analyzing of your attitude and values.

According to(http://ursinus.abroadoffice.net/Grading.html), the U.S. Grading

System at the end of each semester, you will be given a grade for the quality andquantity of your work in a given class. A students academic standing is determinedby the number of credits (classes) completed and his or her GPA. A students GPA iscalculated by multiplying the number of units (credits) attempted in each course bythe grade points earned per course. All grade point totals are added together. Thissum is divided by the total number of credits, creating a final mean value.

Mangatarem Institute was the old name of the school, they renamed it as

Mangatarem Catholic School that was founded in 1956.Mangatarem Catholic Schooloffers

programs in pre-school, elementary and secondary levels. The principal of the school

was Mrs. Rita Fernandez Austria and Sr. Natividad M. Mendoza the directress who led

the school.

Table 1 shows the number of students in Mangatarem Catholic School.

The list of the students enrolled in Mangatarem Catholic School:

Grade/Year

No. of Students

Grade 7 100

Grade 8 833rdyear 145

4thyear 110

All level were divided by two sections. The school has 20 employees, 3 are non-

teaching and there are 17 teachers who supervise the students. They have five

building in this institution to accommodate the employees and the students.They also

have 20 working computers, also they have room for the film showing, and they teach

some advance topic in college in order for them to ready the students for taking up

college.We choose this system for widely used of technology in education. Until today

many school still using the old system type. If we create a computer-based grading

system, it will be more easy and reliable work for the teachers. Many teachers today

are still using the lesson plan. Because of many work of the teachers for the lesson

and for the teaching, it will be less stress for them if they will used computer-

based grading system.

STATEMENT OF THE PROBLEMThe study aims to make a computer-based grading database which

can help aid the problem regarding in recording, and reporting

student grades. Especially it seeks answer the following problems:

1. What are the existing processes in the Mangatarem Catholic School?

2. What are the features to include?

3. What is the acceptance level in term of CARTS?

a. completeness;

b. accuracy;

c. reliability;

d. timeliness and;

e. security?

SCOPE AND DELIMITATIONThe proponents set the scope and limitation of the proposed

system to have a guide in developing the system.

The proposed system is computer-based. It can encode records

of the students for the first grading until fourth grading. And

also can encode the information of students. It can perform thecomputation for the grades to first grading until fourth

grading. It can auto organize the arrangement of the student by

default in student numbers but it can also arrange by

alphabetical or grades. It can also print the record in the

database.

RESEARCH METHODOLOGYThis chapter presents the research methodology. It

consists of the specific discussions on the methods and

procedures that were used, the sources of data,

instrumentation and the data collection and the tools

for data analysis.

The proponents will use the descriptive library and

research method to gather information and gain more

knowledge about the proposed system. We also searched

some data and documentation for more related studies.

The internet, interviews and personal queries was alsoconsidered in laying out the concepts and design of the

proposed system.

WATERFALL MODEL

Design

Requirements Implementation

Verification

Maintenance


9/17

The Waterfall Model is a sequential software

development model in which development is seen as flowingsteadily downwards through the phases of requirements, design,

implement, verification and maintenance. It is signed that the

waterfall model in general can be suited to software projects

which and stable especially those projects with unchanging

requirements and where it is possible and likely that designers

will be able fully predict problem areas of the system and

produce a correct design before implementation is started.

Waterfall development isn't new -- it's been around

since 1970 -- but most proponents still only have a vague idea

of what it means. Essentially, it's a framework for software

development in which development proceeds sequentially through

a series of phases, starting with system requirements analysis

and leading up to product release and maintenance. Feedbackloops exist between each phase, so that as new information is

uncovered or problems are discovered, it is possible to "go

back" a phase and make appropriate modification. Progress

"flows" from one stage to the next, much like the waterfall

that gives the model its name.


10/17

The requirements are fully completed, one proceedsto the design. In this state the software is designed

for a blueprint. The design should be a plan for

implementing the requirements given. Towards the late

stages of this implementation phase, separate software

components produced are combined to introduce new

functionality and reduced risk through the removal of

errors.

Being a very old model it is not recommended for use

on proprietary or customized systems due to its

inability to adapt to constantly changing requirements.

However, in the laze of eons software, the set of

requirements is first engineered and finalize before anydevelopment process, there are already concrete

requirements specifications to work with.

Design Phase.

This is the next stage after the analysis and requirement phase. In thispart, the physical and logical designs of the proposed system are built. The output

of this phase is reflected on the capability of the system. This phase took therequirements identified in the first stage as the initial input. For eachrequirement, a set of one or more design elements are produced as a result ofinterviews, workshops and prototype efforts. The requirements must be reflect on thedesign of the system (Laplante, 2009).

After the beneficiary has approved the specification of requirements theproponents used use case to represent the group of elements like classes andinterfaces, entity relationship diagram to represent the structure data, databaseinstances to describe a complete database environment and lastly, the databaseschema to describe the tables and views in a database together with therelationships between them. Clearly the detailed design stage is the most demandingin terms of resources and time.

Implementation Phase .

This is the stage where the proponents are divided the system according tofunction. The coding of the program takes place in this phase as well as thechecking of the compatibility of the programs to different aspect such as software,hardware and people-ware (Hay, 2011).

This is where the proponents used their skills in programming in certainproblems on the detailed manner, code generation, designing interfaces and featuresof the system. Allow the proponents to assume an implementation of the system to thecompany. Implementations of such specifications involved in modular designs are

those exact processes even to the proponents as constructing the design proponentsto assume an implementation of the system to the company. Implementations of suchspecifications involved in modular designs are those exact processes even to theproponents as constructing the design.

SOURCE OF DATAThe main source of data in the study is the employee

records kept at the Mangatarem Catholic School. The data

being gathered in this project is classified as the

primary and secondary sources.

The proponents used structured interviews as primarysources. An interview guide is used in studying the

system, through the help of Mrs. Rita Fernandez Austria

the principal of Mangatarem Catholic School and the

teachers.The proponents used surveys and internet as a

secondary sources.

DATA GATHERINGThe proponents used the following to gather

related information in developing the Grading System of

the Mangatarem Catholic School.

Questionnaire. A set of objective questions regarding

the proposed systems and problems, it tries to solvewhat was presented to respondents. The results of these

are carefully evaluated so that this study would mean

very much significant.

The Internet. A huge basket of information available at

the tip of our fingers. With connections of many people

compiled knowledge and ideas that are made free for use,

we were able to research related topics of the same

concepts and ideas.

SCOPE DATA ANALYSISThis section gives an explicit presentation of tools used by the proponents

for data analysis.

Use Case.

The proponents used this tool to show all system activities that havesignificance to the users. A Use Case describes a sequence of actions that providesomething of measurable value to an actor and is drawn as a horizontal ellipse. Itcould provide an overview of the usage requirements for a system.

It is used by the proponents to determine the behavioral the requirementsand the missions and goals for the system.

Entity-Relationship Diagram (ERD).

ERD refer to the tool that the proponents have used in data analysis ofthe project. The proponents used this as a tool because to clearly visualize arelational database. An ERD is a special graphic that illustrates theinterrelationship between entities in a database. Boxes are commonly used torepresent entities. Diamonds are normally used to represent relationships and ovalsare used to represent attributes.

Database Schema.

The developers used this tool to layout the structure of the database andthe relationships that exist between elements of the database.A database schema is acollection of meta-data that describes the relations in a database. A schema can besimply described as the layout of a database of the blueprint that outlines theway data is organized into tables. Schema are normally described using StructuredQuery Language as a series of CREATE statements that may be used to replicate theschema in a new database. (see Appendix D).

The developer had utilized a database schema in order to fully illustratethe structure of the developed systems database.


17/17

Flowchart.

The proponents will be used flowhart torepresentThe sequence of the contents of theprocess from the start to the end of processpoints. It was also be used by the proponent toorganize the topics strategies, treatments andoption will work out the details flowchart as aworking map of the project study. Flowchart will

be used to show existing processes.WEIGHTED MEAN.

An average calculated by taking intoaccount not only the frequencies of the values ofa variable but also some other factor such astheir variance. The weighted average of observed

data is the result of dividing the sum of theproducts of each observed value, the number oftimes it occurs, and this other factor by thetotal number of observations.
