CS201: Software Development Methods

1
CS201 Software Development Methods
Prof. Mark Sherriff and TAs

• Course Mechanics
• Course content
• Topics from earlier classes
• CS201 course learning objectives
• Whats the course all about? A quick tour

2
Whats CS201 About?

• What do you think?
• From the Undergraduate Record
• A continuation of CS 101, emphasizing modern
  software development methods. An introduction to
  the software development life cycle and
  processes. Topics include requirements analysis,
  specification, design, implementation, and
  verification. Emphasizes the role of the
  individual programmer in large software
  development projects.

3
Better/replacement course description

• A second course in computing and software
  development, with an emphasis both on modern
  software development and on principles central to
  computer science.
• Topics related to software engineering include
  the development lifecycle, requirements analysis,
  specification, design, implementation, and
  verification.
• Also addresses core computing principles such as
  abstraction, encapsulation, information hiding
  and recursion. More object-oriented programming
  techniques including inheritance, polymorphism,
  event-based programming.

4
Course Topics

• Object-Oriented programming
• Abstraction, information hiding, recursive
  definitions
• Design decisions, design for change and reuse
• OO design inheritance, polymorphism, etc.
• Modern PL features
• Exceptions streams
• Event-based programming networking
• GUIs Threads (maybe)

• Introduction to Software Development Practices
• Professional practices
• Reading/writing specifications
• Planning and designing programs
• Debug and test
• Basic documentation, standards, some maintenance
• Use of tools

5
Course Objectives

• Upon successful completion of this course,
  students will
• Comprehend more advanced principles of
  object-oriented programming and how a programming
  language supports these, and apply these by
  developing larger and more complex programs than
  in their first programming course. (Topics
  include polymorphism, inheritance, collection
  classes, generics, etc.)
• Comprehend and apply principles of design at the
  class and object level. These principles include
  abstraction, encapsulation, and information
  hiding. This also includes the ability to define
  and evaluate class interfaces to solve specified
  design problems, as well as the ability to
  understand, apply, and evaluate the use of
  reusable components to solve such problems.

6
Course Objectives

• Comprehend and analyze problems and programming
  issues such as dynamic memory management,
  indirect object references, and recursion. Also,
  be able to apply this knowledge by implementing
  software that includes these features.
• Apply knowledge of software development practice
  to effectively use strategies, tools and
  environments such as interactive development
  environments, debuggers, testing frameworks, etc.

7
Course Objectives

• Comprehend important basic concepts of software
  engineering and the development of large software
  systems, including the software lifecycle,
  requirements, design, and software quality. In
  their development activities, students will be
  able to apply basic unit testing and carry out a
  software inspection.
• Comprehend the basic principles of the
  architecture of larger software systems, in
  particular object-oriented frameworks. Students
  will be able to apply this knowledge by
  developing a GUI using a framework.

Learning Sources

• Lectures and class activities
• Plan to attend!
• Laboratories
• You must enroll in one of Lab Sections ASAP
• More in a minute
• A textbook to read
• Modern Software Development Using Java. (MSD.)
• 2nd edition vs. 1st edition
• Should have some Java reference text
• See BOCM. One is on-line, free.
• On-line resources especially the Java API docs

9
Necessary Background

• Pre-requisite
• CS101 at UVa (with a C- or better) or the
  equivalent
• This is strictly enforced
• First programming course in Java
• Defining and using classes and objects
• Loops and conditionals
• No more than an overview of inheritance
• Ability to use a Java development tool like
  JCreator, BlueJ, Eclipse
• If youre concerned, talk to me ASAP

10
Course Organization, Communication, etc.

• Course TAs
• One TA will be the Head TA for each lab-section
• Like the instructor for the lab
• Responsible for grade management (entering,
  reporting, updating)
• More TAs will grade assignments and exams
• Instructors role
• Lectures, planning, course-design, student
  issues, etc.
• Questions
• Send general questions to Collab Message board!
• Send grade questions to your Head TA via private
  message
• Send your instructor email on other things when
  appropriate
• PLEASE include CS201 in the subject line
• Course web page http//www.cs.virginia.edu/cs201

Instructor Information

• Prof. Mark Sherriff
• Office Olsson 228A. Phone [phone]
• Email sherriff_at_cs.virginia.edu
• Office hours MTWRF, 200-300 pm

12
Clickers and In-Class Exercises

• Having a clicker is required
• Why?
• Success in other classes here at Uva
• Trial experiment last spring in CS201 showed
  measurable improvements in learning from class
  meetings
• Students tells us that CS classes should be more
  interactive and engaging

13
Laboratories

• Lab activities are the central learning activity
  for CS201
• Sometimes a pre-lab activity. (Must do it!)
• In lab a lab exercise
• Coding, group exercise, quiz, etc.
• Graded on participation mostly
• Programming Assignments AKA Homeworks
• The real homework. Graded on quality.
• Often done in pairs (according to certain rules).
• Do outside of lab. Submit electronically.
• Project(s) slightly larger assignments, done by
  groups of 3 or 4
• Anticipate 5 homeworks plus 1 project

14
Other Policies Etc.

• Honor Policy (read the course memo carefully)
• It applies in CS201!
• Students and faculty at UVa should (re)commit to
  its principles and policies
• See each assignment for rules about collaboration
• Do not copy other peoples code! Do not give
  your code to others outside the rules!
• Some assignments allow you to talk to classmates
• This really shouldnt lead to identical code,
  should it?
• Violations zero on the assignment, submission to
  the Honor Committee

15
Need Accommodation?

• Learning Needs (LNEC) students
• Get in touch at least one week before an exam
• If you need other things, contact me.
• Any student who thinks s/he may qualify, contact
  the Learning Needs center
• If you have an illness, trip, etc. that requires
  you to miss an exam or lab
• Contact me in advance or as soon as possible
• If you have any kind of issues that affect your
  attendance or performance, do not hesitate to
  contact me!

16
Expectations

• I expect you
• To make your best effort
• To prepare when required or do other activities
• To come to class and do the readings
• To let me know if there are problems or issues
• You can expect me and the CS201 team to
• Be objective and fair and understanding
• To keep your informed about assignments and
  grades
• To listen and respond when you make comments or
  suggestions
• To make do my best to make this a good course

17
In-Class Activity

• In groups of 2-4, talk about the following things
• Then, Ill ask some groups to report to the class
• First, share your name and major
• Second, talk about what worries you about this
  class
• Third, come up with at least 2 questions about
  the syllabus.
• Go!
