4 1. Introduction Currently in Afghanistan s schools, usage of new technologies is very limited. Most schools in Kabul have dozens of computers but they are only used for teaching the computer subject and nobody uses them for administration purposes. There are some limited numbers of schools that use a computer instead of a typewriter by using Microsoft Word or for saving some data in Microsoft Excel. However there are numerous tasks that can be done by computers if they are programmed to do, such as managing students grades or creating the school timetable. Timetable creation and students' grade management is two of the most tedious tasks of administration staff and teachers of schools in Afghanistan, which they have to perform manually at the beginning, mid and end of each school year. The administration staffs of the schools that are responsible for scheduling create separate timetables for students and teachers. They also have to take care that each teacher in the schools should have a maximum of 35 working hours per week, as well as assigning rooms to different courses, managing laboratory access schedule and creating exam date sheets for both teachers and students. Managing students' grades is another task of administration staff and teachers of the schools, which is very time consuming and error prone. Many people are involved into this process. So there is a risk of treachery in students' grades. Each subject teacher has to take a print out of a list with many columns and rows and fill it with names of students and their grade for that subject. Then the subject teacher has to submit the list to the class teacher. The class teacher collects all the lists from all subject teachers and creates a huge table for calculation of students' grades and position in the class, which is then rechecked by the administration staff of school for correction. For this reason the grade lists are very error-sensitive, if the list contains any streaks and unusual pen marks then the list is considered void, and the associated teacher is asked to redo his/her task. This is very time consuming for the class teacher to calculate and for administration staff to check for validity. That is why the School Management System is designed to improve school management in Afghanistan. This software is designed by local experts because the software needs to comply all the needs and 4

5 standards of Afghan schools, which can be very well considered and programmed only by the local experts of the country. 2. General Goals Timetable and Student grade management system software is a web application which is designed for Afghanistan's schools. This software can ease some tasks of school managers such as creating school timetable and also managing student s grades. 3. Current System Currently administration offices in most of afghan schools do not use computers for performing their daily tasks. There are a limited number of schools that use Microsoft Office products, such as Ms. Word and Ms. Excel for performing their daily administrative tasks. Most of them do not even have the information that computers can make a great difference in the way they are doing their tasks when they are programmed to do so. The only school in Kabul which uses software that are built specially for schools is the International School of Kabul (ISK), which uses Grade Quick software for calculating student s grades and Admin Plus for managing student information and printing student s report cards. Both of the above software are proprietary software which are designed by Rediker software company. Today in Afghanistan s schools all the tasks and calculations are being done manually and paper based. In both of the tasks the administrative staff and the teachers are involved. For small schools managing student grades and creating timetable can be an easy task, but for the big schools like many governmental schools this task is very difficult. The procedures of both of the tasks are described in the following sections of the document. 3.1 Timetable Creation Process Accomplishing this task is the job of academic affairs vice principal of school. The Ministry of Education (MoE) has a curriculum that is sent to all schools in the country so this way the subjects that are thought in all schools are the same country wide. In this curriculum this is stated that which standard will have to be taught which subjects and how many hours per week. So first of all the vice principal, will see the curriculum which comes to the schools by MoE and associates each teacher with his/her related field's subject for each class of a standard according to the teacher s profile book. According to the experience and position of the teachers the higher standard classes like 12 th, 11 th... standards are assigned to the teachers with more experience and 5

6 higher position. Then according to this list, the timetable is put in days of week in a table. And at last, one big table is created with all the class names of the school and the subjects. 3.2 Grade Calculation Process The class teacher creates student list for each and every subject of this class by writing name and father s name of students, the subject s name and the subject teacher s name. Then every subject teacher will take a list from the class teacher and give exam to the students. After the exam the subject teacher will be given Student List paper which is a table printed on paper by MoE, the teacher enters the marks each student has achieved both in number format and in alphabet, in the student list. Later the subject teacher will submit the list to the class teacher. The class teacher collects all student lists of all subjects and then creates three copies of a big table (in some schools one of the copies are created by the head master) which has entries for every student with marks of all of the student s subjects. Later these tables are inspected and calculated again with the presence of class teacher and three inspectors. After the inspection the examiners and the class teacher sign and certify that all the marks were correctly entered and calculated in the table. Then one copy of this table is sent to Department of Education of the city for further inspections and to be stored there. 4. Proposed System 4.1 Overview The proposed system is intended to provide the facility of automating the administrative tasks such as student grade management and timetable creation for the administrative staff of Afghanistan s schools. This system will be a client server system, meaning the one system acts as server, and three other systems will be its clients. Four people who will access the system through the clients will be the system administrator, the principal and both the academic affairs vice principal and the administrative vice principal of the school. The academic affairs principal of school is responsible for creating the school s timetables and also managing student information and the other is responsible for resource management. 4.2 Functional Requirements 1- Create, edit, delete, store and print timetable 2- Create, edit, delete, store and print exam time table 6

7 3- Searching timetable by year 4- Store, edit, delete, calculate and print students grade 5- Search students grade per class / per ID or by name and father's name 6- Add, edit and delete Rooms, Classes, Subjects and Departments 7- Be able to add a student's previous marks who has joined school having a leave certificate from another school. 8- Change user s password 9- Set editing password 10 Set default language 11 Create, Edit, Delete, Activate, Deactivate user accounts. 12 Take and restore backups Input Data The input data for the system is the student s grade in decimal number format, name/number of rooms, classes and names of departments and subjects which are all in String format Languages The languages that the system will support are the local languages spoken in Afghanistan which are Dari and Pashto, plus the English language. The default language for the system can be set by the user which can be either Dari or Pashto. 4.3 Non-Functional Requirements User Interface and Human Factors The system will have a friendly user interface and support for the local languages so that there is no problem for users who will speak either of the country's languages. The system will only have four users, one is the principal of school, the second is the academic affairs' vice principals, the third is the administration affairs vice principal and the last one is the system administrator. The principal will only have access to the editing password and can view the information on the system but all the other tasks will be performed by either of the vice principal, so there is a need for implementing three access levels Documentation The system will be very well documented, which includes the system documentation and also the user manual. The system documentation is important because this may help in further development of the 7

8 system and the user manual is necessary because the user may need some basic training or help about the functionality of the system Hardware Consideration The system will be installed in one computer, which will be placed in a server room or in the principals office. The server computer must have the following characteristics as an average Server Hardware requirements: HDD: 500 GB RAM: 512 MB or greater CPU: Dual Intel Pentium 4 CPUs VGA: 256 MB Backup Media: DVD Monitor, Mouse and Keyboard is needed. UPS: 2000/ 3000 VA Client Hardware requirements: Average desktop computer LAN card Printer UPS: 2000/ 3000 VA Software Requirements Server Software Requirements Linux operating system (Ubunutu) Apache web server Mysql A web browser (i.e. Mozilla Firefox) Client Software Requirements The client will not need a specific kind of operating system, because the school management system will be a web application so it doesn t matter which operating system the client uses. So the operating system in the client can be Linux or Windows and a web browser which could be Mozilla Firefox or Internet Explorer Performance Characteristics The system will be well programmed so that it doesn t use a lot of system resources and will be fast and accurate. 8

9 4.3.6 Error Handling Input Error Handling The system will be able to give error messages when the user enters wrong input into the fields or leave an important field empty. For example the user can never enter a negative number or any other character except numbers in the students mark's field. If this happens then the system will give error messages regarding the data type Error Handling Extreme Conditions The system needs to be backed up regularly by the system administrator so that in the worst case which can be a system crash, the data can be restored to the system after the repairing it System Interfacing The system will not interact with any other systems for now, but this functionality maybe applied in future, because the student grades are manually sent to the Education Department of the city which can be somehow shared electronically after implementing such a feature in future. Also the functionality of setting the default language will not be implemented in this version of the software Quality Issues The system will be programmed in a way that it won t allow unauthorized access to the system resources. This system will be able to run on any kind of operating system. The system will have error handling mechanism System Modifications The system will be able to do all the tasks that are mentioned in functional and non functional requirements sections. Other functionality such as interface between this system and the student record system in Education Department can be created in future, for bringing more improvement to the system Physical Environment The place that the server will be kept is a server room or the principals office. The system needs to be protected from dust, humidity and direct sunshine therefore the placement of the system must be done by taking these points in consideration. 9

10 Security Issues The system will have user accounts for its users. The passwords will be encrypted. And the https protocol will be used for access to the system. There is no such functionality in the system by which the user can register himself to the system. This is because there are only three users in the system apart from the system administrator, so the user accounts are created by the system administrator. The system administrator can activate, deactivate, create, edit and delete user accounts, because every once in a number of years the principal or the vice principals may be changed, but the user names for them will be constant. At this time the system administrator will have to deactivate the account until the new person takes over the job and the system administrator then activates the account and the only thing the new user will have to do is to change the passwords for him/herself Resource Issues The system administrator of the school will be responsible of backing up the system regularly by copying the database to a DVD and maintain the system and install updates. 4.4 System Model Scenarios Timetable Creation Scenarios Timetable Creation: Current Situation: In the beginning of the new school year, Sarah has to create a new timetable for the first semester. So she creates a list of all the teachers in the school sorted according to their experience which is indicated by the teacher position in the teacher profile book and their major field. For creating the timetable she starts with one subject and creates list of all teachers that teach that subject. Sarah wants to start with physics subject so first she creates the list for physics teachers. After listing the teachers she will find out how many classes of each standard are there because the number of students in a standard gets more than 40 in large schools. So she finds out that there are ten classes of 12 th standard, eleven of 11 th standard, ten of 10 th standard and two of 9 th standards. Then she calculates the total number of teaching hours in a week. 10

11 There are six days in a working week and every day each class has to be taught for six periods/hours so the total number of teaching hours is 36hours. Now she finds out the sum of all classes that they have in school from the above number of classes which becomes 33 classes. So for finding total number of teaching hours for all 33 classes she multiplies 33 to 36 and the result is 1188 teaching hours. After that, Sarah will decide how many hours each teacher should teach. The first name in the list is Karim Khan who is the head of Science department so she has to give him only 12 hours to teach because he has a lot of work to do apart from teaching. So Sarah takes out 12 hours from the total teaching hours and what remains is 1176 teaching hours, and she gives 24 hours for all the other teachers. Later Sarah takes the teachers list and assigns Karim khan to classes 12 th A, 12 th B, 12 th C and 12 th D, each of those classes have to study three periods of physics per week which makes 12 hours per week for Karim Khan. And in the same order she assigns classes to other teachers, but with the difference that she will give 8 classes per teacher so that other teachers should teach a minimum of 24 hours per week (and a maximum of 36 hours/week). When this task is finished, Sarah will make a table with days of week and six periods per day for all of the classes in a big sheet. And then she will put each subject and its teacher in the cells of this table and will also take care that no two subjects of the same teacher should come in the same day and period. She will give Karim Khan a priority in this task so she will put his subject in the days and periods that he would like. She repeats this task for all the other subjects of all the classes. Future System: Sarah has to create the time table for the new school year, so she logs in to the system and clicks on Timetable Management, in the next page she clicks on Create Timetable, she inserts a title for the timetable and the timetable is created by the system and she can view, edit and print the timetable. Edit Timetable Sarah has to replace math which is on second period on Monday by Dari which is on third period on Thursday for 8 th B class, so she logs in to the system and then clicks on Timetable Management then she clicks on Edit Timetable. After that she opens the drop down box of the Math cell and selects Dari and in Dari cell she selects Math. Then she saves the changes. 11

12 Delete Timetable Sarah wants to delete the timetable so after logging in to the system she clicks on Timetable Management and then on delete timetable. Exam Timetable Creation: Current situation: Sarah has to create the mid-term exam timetable so she arranges a table with rows and columns which include (date, day of week and subject as columns and class names are written in the first row) then she puts one subject and its teacher for each class in one day and makes sure that no subject with the same teacher is repeated for two classes in one day. Future System: Sarahh logs in to the system, first she goes to Timetable Management and then clicks on the Create Exam Timetable and enters the start and end date for exam and a title for the date sheet. And the timetable is saved and can be edited, deleted or printed. Note: Edit and Delete work the same way for Exam timetable Student Grade Management Scenarios Students Grades Calculation: Current Situation: Actor(s): Wali (Class Teacher) When the students pass their midterm or final exams then Wali has to collect the marks of all the subjects of his students from each subject teacher and calculate the results for each student. At the end he has to prepare the result sheets for all the students. Future System: Add Grades: Wali (Class Teacher) When the exams are finished Sarah takes the mark list of each subject of Wali s students. She logs in to the system. She clicks on Add Grades then select 7 th A class name from the drop down box, the system displays names of all subjects that are taught in 7 th standard plus the names of all students in 7 th A class. Then she enters the marks of each student for a subject to the system and saves the changes after marks of each subject is entered. She repeats this for each class. Calculate Grades: 12

13 When marks for all subjects of one class is entered in the system, Sarah clicks on calculate results and can see the students sorted by position and also can print them. The system will show the student's in-class position. Top Three Students: To find out who are the top three students of school, Sarah logs into the system she clicks on Top Students link, then the system displays a drop down box where she can select Class wide, Standard wide or School wide options to find the top three students, when she selects School wide option the system displays the top three students of the school, and when she selects standard wide option the system displays another drop down box from which she can select a standard and the system displays the top three students for that standard. And when she selects class wide the system displays a drop down box where she can select a class and the system displays the top three students for the selected class. Transcript Creation: One of the 9 th standard students comes to Sarah and says that she wants to change her school, therefore needs her transcript. Sarah logs in to the system she searches the student by name and father s name and then clicks on create transcript. The system creates a transcript of the student based on year and all the marks that she had taken in these nine years are listed in the transcript. Sarah prints the transcript and gives it to the student. Edit Grades: Current Situation: Usually grades of the students are no longer editable once they are entered but there is only one exception that when a student is not satisfied with his/her grades in a specific subject, he/she can complain to the administration office of school by writing an official letter and can get the permission that his/her paper must be revised in his/her presence and the presence of three inspectors that can be the subject teacher and two other teachers who are selected by the vice principal. So in this case if there were any mistakes made by the subject teacher, then the committee will give the student the marks he/she deserves and this way grades of the student can be edited. Future System: Actors: Seema (9 th class student), Wali (math teacher), Sarah (academic vice principal) and Kabir (principal) 13

14 Seema has gotten 60 in math subject exam but she is not satisfied with this marks because she submitted a good paper so she goes to the vice principal Sarah and requests for revising her paper. Sarah informs Kabir the principal about this issue, Kabir creates the committee which s members are Wali,Kabir and Sarah. They look at Seema s paper and find out that Wali had made a mistake in checking the paper and instead of 90 he wrote 60 on her paper. So Sarah will now have to edit Seema s marks in the system. Sarah logs in to the system and clicks on Edit Grades button. Another page appears where she has to choose the class title, and then the student name and the subject that she wants to edit its grade. After she chooses class 9 th B then Seema s name and math as the subject, the system shows Seema s current math grade and also there is a button named Edit when Sarah clicks on this button, a text box appears which says enter editing password. This password is only known by Kabir so Sarah asks Kabir to come to her office and enter the editing password. Kabir comes and enters the password and the table cell for Seema is now editable and Sarah writes 90 in it and saves the changes. Now Sarah has to recalculate the results of all students of class 9 th B because there is now 30 marks difference in Seema s total number so her position might change in the class. So she goes to Calculate Marks and chooses 9 th class and clicks on Calculate and the system shows the changes. Now Seema has got the second position in her class and Sarah prints the result. Change Editing Password Actor(s): Kabir (principal) Kabir wants to change the editing password so he logs in to the system. He clicks on Change Editing Password button and the system asks him to type the old password and then he has to type the new password in the two text boxes below the he click on Done button and the password is created and stored in the system. And he clicks on home link to go back to homepage. Change User Password Sarah wants to change her password so she logs in to the system. She clicks on Change Password button and the system asks her to type her old password and then she has to type her new password in the two text boxes below the she click on the change password button and the password is created and stored in the system. And she clicks on "home" link to go back to homepage. 14

15 Student Promotion Scenarios Current Situation: The school year is finished and the results are known so Sarah has to promote the successful students to the next grade, so she makes a table based on last year s results table. In the table she writes the title of each class and in the students column she adds the number of successful students of last year, the failed students from one grade higher, the excluded students (those who didn t have the right to study in the previous year because of lack of presence in the class) and the second chance examined students. Then she calculates the total students for that standard. She has to take care that she has to divide the total number by 40 because there should be no more than 40 students in one class, so if the total was more than 40 she should make more than one class of one standard and name it A, B Future System: The school year is finished and the results are known so Sarah has to promote the successful students to the next class so she logs into the system, she clicks on Manage Students Grade and then Promote Students to Next Standard and then for each class she clicks on Promote to Next Standard button and the system takes the passed students from this grade, failed students from one grade higher, excluded students of this grade and second chance examined students and all of the students are promoted. Sarah selects 11 th standard so all of 11 th classes are listed, then she selects all of the 11 th classes and clicks on promote to next class. Because the total number of students is 386 the system creates 10 classes of this grade which are named as 12 th A, 12 th B, 12 th C Promoting one student: Current situation: When a student is very intelligent and wants to leave one grade behind, is examined in the beginning of the school year, if the student is successful he/she is promoted one grade higher. For this reason Sarah will make a report by writing his/her previous standard's grades and his/her promotion exam marks. This paper will be signed by head master and principal in either cases of the student s success or failure. If the student is successful, he/she is promoted to the next standard. Future System: After logging in to the system, Sarah clicks on Promote Students to Next Standard and clicks on promote only one student then she 15

16 searches the student by name and father s name. when the system finds the student she cant promote the student to the next standard directly. So she clicks on Add Promotion Exam Grades button and she selects the standard that the student is leaving behind and adds the student's grades for all the subjects that are taught in that standard. And at the end she clicks on Promote student to the next Standard button Graduate Students Report Scenarios Current Situation: Actor(s): Sarah (Vice principal) When the school year is finished the successful students of 12 th standard are considered as graduates and the school needs to prepare a report of the graduated students information so that is sent to Department of Education. Sarah will write the names, grades and other information of the graduated students in a register book and send it to Department of Education. Future System: After logging in to the system Sarah will click on Manage student Grades then she clicks on Create Graduate Report, the system displays a page where Sarah can select a year and then she will click on create graduate report and then the system will create a table of all graduated students of the specified year and their necessary information, and Sarah can print them Adding Previous School Marks of a Student that comes to school holding a leave certificate from another school Scenario When Sarah adds a new student who changed school from another school to this school, she will also have to enter the student's previous grades. So she is already logged in to the system and she clicks on Add Previous Grades button and the system displays a page where Sarah can select a standard and add the student's grades for that standard and submit the changes at the end, and she can add grades for all of the previous standards of this student Move student from one class to another in the same grade Scenario Some days after the promotion of students from one standard to the next some new students are admitted to the school in 5 th standard and 16

17 they need to be added into the system, but there is a problem that all classes of 5 th standard are full so the system adds a new class of fifth standard automatically and adds the new students to this class but the number of all these students is 15 so Sarah thinks that it is a good idea to move some students of other 5 th standard's classes to this new 5 th class. So she clicks on Move students preserving their standard link and then she selects the standard, then the classes of the selected standard appear, she selects the class from which she wants to move students and also the destination class, after that the students of source class appear in the list so she selects the names of the students and clicks on move to destination class Search Student Scenario Search Student by Name and Father s Name Actor(s): Sarah (Vice principal) One of the graduated students of the school comes to Sarah and says that she needs her transcript. Sarah logs in to the system she must search the student by name and father s name so she clicks on Search Students. Another page appears where Sarah can enter name and father name of the student and click on Search button, when the student is found Sarah can view the student s information or print her transcript or promote the student to one standard higher Add Resource Scenarios Add Subject: Sarah logs in to the system for the first time so she needs to add subjects in the system. So she clicks on Add Subjects button and enters subject names and saves the changes. Edit/Delete Subject: Sarah finds out that a subject name is entered wrong in the system so she clicks on Subjects button then she can edit or delete any subject that she wants. Add Room: Sarah logs in to the system for the first time so she needs to add room numbers/names in the system. So she clicks on Add Rooms button and enters room numbers and saves the changes. Edit/Delete Room: 17

18 Sarah finds out that a room number is entered wrong in the system so she clicks on Rooms button then she can edit or delete any room that she wants. Add Class: When the new school year begins and new students are admitted to the school Sarah needs to add students to classes so Sarah logs in to the system and she clicks on Add Classes button and enters class names and saves the changes. Edit/Delete Class: Sarah finds out that a class name is entered wrong in the system so she clicks on Classes button then she can edit or delete any class that she wants. Add Department: Sarah logs in to the system for the first time so she needs to add department names in the system. So she clicks on Add Departments button and enters department names and saves the changes. Edit/Delete Department: Sarah finds out that a department name is entered wrong in the system so she clicks on Departments button then she can edit or delete any department that she wants. Set Room to Class: Before creating the timetables Sarah needs to set a room to every class, so she logs in to the system, then she clicks on Set Resources link and then a page appears where she can set classes to rooms, set teachers to classes and set subjects to teachers. She clicks on Set Room to Class link and a page appears where she can click on a drop down box to select a class and a room in another drop down box, and click on Set button.
