Project Overview

• The motivation of the project comes from the
  English Language Programs desire to have a
  software which facilitates the input of data and
  places international students into proper levels.
  This should be done automatically by the computer
  instead of manually, making the process easier
  and requiring less time and work.

Use Case
19
Project Requirements(1)

• Placement Of New Students
• Purpose New students will be placed in a level
  of the ELP based on their English Proficiency
  Test (EPT) score.
• Input The user will select import from Excel
  button to invoke EPT score from the Excel file
  that is provided by the library.
• Processing The software will calculate the total
  score which is the overall guiding factor for the
  new student.
• Output Place new students in a suitable level
  based on their EPT score.

Project Requirements(2)

• Placement Of Returning Students
• Purpose The purpose of this part of the
  application is to enable the user to place the
  returning students in the appropriate level based
  on three criteria.
• Input1-EPT Score from the test taken at the end
  of the previous semester.
• 2-Achievement test score given in
  every class at the end of every
  semester.
• 3-Positive teacher recommendations .
• Processing The ELP Helper first checks the EPT
  test, If the EPT test has not been changed to let
  a student move up to higher level, it checks the
  teacher recommendations and achievement test
  score.
• Output Place students in the suitable level,
  either they move up to another level or stay in
  the same level.

Project Requirements(3)

• Divide levels in subgroups
• Purpose The purpose of this part of the
  application is to enable the user to divide up a
  big level into many sections so that teachers can
  recommend their students via the internet.
• Input Select students name, groups name,
  level, and current year.
• Processing The ELP Helper divides up the level
  into groups depending on the user selection.
• Output Each student will be placed in his/her
  group in his/her level.

Project Requirements(4)

• Teacher's recommendation
• Purpose The purpose of this part of the
  application is to enable teachers to recommend
  and enter the achievement score of their
  returning students via the internet.
• Input A teacher enters password and username to
  login, they then fill in boxes, and enter
  percentage for the students score.
• Processing Save these scores in the database to
  use for student placement and see if the
  achievement score is less than or greater than
  80.
• Output Place students into the propel level
  based upon their EPT score, recommendation, and
  achievement score then print the class
  achievement report.

Cost Estimate

• The COCOMO model developed by Barry Boehm will be
  used to estimate project effort and project time.
  The ELP Helper will be an application of average
  complexity but with an extensive database. The
  COCOMO model classifies such projects as
  organic and provides the following equations to
  calculate effort and time
• Effort 3.2 EAF (size)1.05
• Time (in months) 2.5(Effort)0.38
• Where
• Effort number of staff months (PM)
• EAF effort adjustment factor
• Size number of lines of code for completed
  product. It is measured in KLOC (thousands of
  lines of codes)
• Time total number of months

32
Cost Estimate(2)

• The EAF value based on the adjustment factors
  being assumed evaluated to 0.9. I estimated the
  size to be 2000 LOC based on the current
  prototype and similar examples. The effort
  evaluates to
• Effort 3.20.92.01.05 5.9 staff months
• The time can now be calculated as
• Time 2.55.90.38 4.9 months
