- 2. 4.0 The Existing System 4.1 Company Background Metropolitan Academy of Manila ( MAM ) is a religious, non-stock, non-profit educational institution founded in August 1996 in Sta. Ana, Manila. It is supervised and operated by One Body Christian Church and Ministries. Metropolitan Academy of Manila ( MAM ) offers pre-elementary, elementary and high school levels to qualify students attaining Excellence in Academic and Christian Education and Spiritual Maturity to cope with the Christian mandate of world evangelization. It is their mission to instill the Authentic Christian identity among students, educate and train them in the ministering of the Lord Jesus Christ, commitment to God and service to our country and fellowmen. Everyone in the school are all willing to help and pray for the general welfare of each family and the community at large and bring the message of peace and reconciliation among men in all walks of life. Complementing the school’s desire to teach each student the fear of God and respect for authority and elders are the team-oriented organization of Faculty Teachers, Staff, Administration and Board of Trustees sensitive and responsive to needs and changes relevant to the institutional aims. At present, the school employs a total of twenty-eight (28) teaching and non-teaching personnel and is catering to an average yearly enrollment of seven-hundred (700) students. As an institution being supervised by One Body Christian Church and Ministries (OBCCM), the school maintains very affordable tuition fees that are suitable to average to low income families. Due to their limited funds, the school maximizes its workforce to attend to every student needs that results to overloaded teachers and school personnel.
- 3. Although the school has a handful of computers donated to them, they still use the traditional way of maintaining files and records that are manually done. 4.2 Description of the System The current system being employed by Metropolitan Academy of Manila follows the traditional methods of recording, calculating, and maintaining student grades and records. Everything is done manually. Student Information are written on paper forms during enrollment. The registrar prepares a list of ofiicial students and give copies to the principal and to the teachers. The teachers writes down the names of the students in their class records for every subject and section he or she is handling and enters the rating of the students for every grade component. The teachers manually computes the grade of the students using a calculator and submits their class records to the principal for checking. The principal checks the grades one-by-one and of errors are found, the class record is returned to the teacher, who re-computes the grade and submit it again to the principal for checking. Correct and verified grades are then given back to the teacher to be submitted to the registrar who prepares the students’ report cards. This type of system is very tedious and takes a long time. Manually calculating, checking and re-computing the grades of students are very difficult and are very prone to human errors. Added to this is the money being spent by the school for paper files and forms, cabinets and other things needed to store student data and records.

- 5. 4.4 Data Dictionary Class Record/ Grading Sheet- a written document consisting of student names, and their grades for each grade component Grade- numeric equivalent of a student’s performance in subject or grade component. Erroneous Subject Average Grade- Subject Grade Components that contain errors in calculations that are returned to the teacher for re-computation. Official List of Students- List of student names who are officially enrolled in the school for the current school year. Registrar- the person in charge of recording and maintaining student information and grades. Student- a person who is officially enrolled for the current school year. Student Report Card- a report given to the parents containing the grades of the students for a given quarter. Subject Average Grade- The grade of the student for the subject as computed by the teacher and that appears on the Student Report Card. It is determined by the sum of all ratings for the different grade components divided by the total number of grade components. Subject Average Grade for Checking- computed grades based on the different grade components to be checked by the Principal for accuracy.
- 6. Subject Average Grade for Recording- Student grades that have been checked and verified to be correct by the principal that is returned to the teacher for submission to the registrar who then records it on the student’s Report Card and Transcript of Record. Subject Grade Components- Activities undergone by a student in which he or she is rated by the teacher. Grade components are composed of the following: Attendance- presence or absence of a student during class periods Seatwork/recitation- activities given by the teacher to be performed during class hours. It can be oral (recitation)n= or written (seatwork). Quizzes- short test on topics previously discussed or given as assignments. Periodical Exam- long test given at the end of every quarter covering topics discussed within the quarter. Subject Grade Components Rating- the mark or rating given by the teacher to the different subject grade components based on the performance of the student in these grade components. Teacher- A school faculty member who is teaching the subject, rates student’s performance on the different subject grade components, and computes for the subject average grade of the student.
- 7. 4.5 Problem Areas Three inter-related problem areas have been noted in the existing system of the school: Redundancy of work and data. There is redundancy of work and data, particularly when it comes to the recording of the names of the students and in the checking of their grades. The students list that is given by the Registrar has to be written by the teachers in their class records. This is done by every teacher for every subject the he or she is teaching and for every section he or she is handling. If a teacher is teaching three subjects with the same section, then he or she has to write the names of the students three times, one for every subject handled. The principal has to manually re-compute the grades of the students just to make sure that these are correct before these can be submitted to the registrar. Time spent in calculating and checking grades. Grades are recorded and computed manually by teachers. This is a very tedious task and is very time consuming. The principal has to check each grade to make sure that no errors are committed in the computation. If errors are found, it goes back to the teacher concern to make the necessary changes. It then goes back again to the principal for checking. This cycle continues until all the grades have been verified to be correct. Accuracy of Information. Aside from being time consuming, manual method of recording and computing for the grades of the student is prone to human error. More often than not, teachers rush through deadlines in the submission of grades and because of this, the accuracy of the grades are effected. The principal still has to double check each grade to ensure its accuracy.
- 8. 5.0 The Proposed System 5.1 System Overview The proposed system is developed using a VBA Excel. It improves working methods by replacing the activities done manually with the computer-based system. By automating every activity of the manual system being employed by the school, work becomes easier and grades are computed accurately in less time. The proposed system in simple, interactive and has a very user-friendly interface such that even those with little or no knowledge about working with computers can easily operate it. A welcome screen starts the program and the teachers log-in by entering their username and password. 5.2 Process specification The proposed system is composed of three main modules, namely the registration module where pertinent student information are entered, the subject module, where the teacher enters the rating of the student for each grade component, and the grade computation module, where the grade of the student is calculated based on the inputted ratings for each grade component. After the teacher logs-in, the main menu is displayed containing three (3) options, namely, to enter student information, to enter student grades, or to view student information.
- 9. The process begins with the entry of student information (module 1). This is where pertinent student data, such data, such as student name, address, parents name, contact numbers, etc., are entered and stored in a student information database. Using the data from the student information database, the teacher chooses a subject and enters the rating of the student in each grade component (module 2). The grades are stored in the subject’s database. The grades stored in the subject’s database are then retrieved and used in computing for the grade of the student (module 3).

- 11. 5.2.2 Data Dictionary Component Grade- the mark or rating given by the teacher to the different components scores, based on the performance of the student in these grade components. Components Scores- the scores obtained by the student in a particular subject component. Student Information- pertinent data about the student such as student’s name, address, birth date, parents’ name, etc., Student Information Database- the database where student information data are stored. Subject Database- the database where the component grades and subject grade are stored. Subject Grade- The grade of the student for the subject resulting from the subject grade computation process. 5.3 Data Specification 5.3.1 Entity Relationship Diagram The proposed system is composed of 3 entities are shown in the following Entity Relationship Diagram:
