Lesson Plan
Course Title: Advanced Computer Programming
Session Title: Software Modeling
Lesson Duration: 2-3 days
Performance Objective:
Upon completion of this assignment, the student will be able to:
• use advanced modeling techniques to document software,
• identify modular design concepts through documentation, and
• use current, appropriate modeling and analysis tools (UML)
Specific Objectives:
• identify the key attributes of source code that can and should be documented
• construct UML diagrams to model the structure and relationships between parts of a
program
• construct diagrams that document components of a software object
Preparation
TEKS Correlations: 130.277 (c)
• 3.H – use advanced modeling and analysis of functional requirements
• 7.H – identify modular design concepts
• 5.F – use appropriate modeling and analysis tools

Labs (KEY is provided for PreLab and Lab)
PreLab and Lab Handout
Student Files
SpaceGame (Bullet.java, Enemy.java, EnemyBullet.java, Invaders.java, Ship.java,
Stars.java) (PreLab)
WallBuster(BreakIn.java, Brick.java, Paddle.java, Ball.java) (Lab)
Materials Needed:
Copies of PreLab and Lab
Student Files should be loaded on student computers, or provided in some manner.
It is useful to have copies of the Student Files, but not necessary if the students use the files
from the computer.
Equipment Needed:
No special equipment is necessary to complete this assignment.
Students should have knowledge and experience with inheritance and extending classes.
Introduction
MI
Introduction (LSI Quadrant I):
Imagine being given a program that has several class files. What if you were asked
to add a feature to the program? How difficult do you think that would be? Do you
think you would know which files you would have to change? How would you
determine what other files would be affected by changes you make?
Software modeling allows you to provide a “road map” to a computer program so you
can see where things happen in the program and how different classes affect each
other.

Application
MI
Guided Practice (LSI Quadrant III):
The PreLab can be a good opportunity to practice with the students. It would also be
beneficial to select a program the students have previously written and practice
modeling it.
MI
Independent Practice (LSI Quadrant III):
Following the presentation, students should be provided with the lab to complete on
their own.
Summary
MI
Review (LSI Quadrants I and IV):
Have students model a program written by a different student.
Evaluation
MI
Informal Assessment (LSI Quadrant III):
You may use the PreLab to assess whether or not the students are progressing well.
The PreLab is important in determining whether or not the students are ready to
complete the lab.
MI
Formal Assessment (LSI Quadrant III, IV):
Software Modeling Lab
Extension
MI
Extension/Enrichment (LSI Quadrant IV):
This lesson only covers documenting code. Students should find software models
and see if they can develop source code from the models. The book Killer Game
Programming (see references) has several models that would make good exercises
to work from.

Software Modeling – PreLab
Purpose: At the end of this lab, you should be able to use UML diagrams to identify
components of a system and generate UML documentation for an existing project.
Materials: You will require a java compiler and editor, the SpaceGame example source code
and the documents for this lab.
Directions: Compare the following Relationship Diagram with the example source code and
answer the questions.
Questions:
1. How many classes are there in the project?
2. Two of the classes are extended from other classes. Which classes are extended and
what are they extended from (e.g. Cat extends from Pet)?
3. Examine the Invaders object. What objects does it use (what objects does it contain)?
4. Fill in the Class Diagram for Ship.

Grading note: for the attributes, the private indicator may be left out, and for methods the
public indicator may be left out as these are the expected visibility modifiers.
