Kevlin is a consultant and trainer whose work focuses on patterns and architecture, programming techniques and languages, and development process and practice. He has been a columnist for various magazines and online publications, including The Register, Better Software, Java Report, CUJ and C++ Report.

Course Highlights:
Object-orientation is now considered a mainstream approach to software development. Current trends include component-based development, distributed object computing, design patterns, object modelling — most popularly using UML — and agile development methods — such as Extreme Programming. The principles on which object-orientation is based are drawn from good software engineering theory and practice, balancing the practical aspects of day-to-day development with longer term goals such as management of complexity. As such, object-oriented development supports different project styles and sizes. It can be hard for programmers to develop a working understanding of OO without hands-on experience; explanations of terminology are useful but cannot reasonably change how a programmer approaches development. The Practical Objects course aims to introduce OO concepts, terminology and practices to software development professionals. The course is based around lectures, discussion and hands-on programming exercises. To avoid the detail and distraction of a language such as Java, C# or C++, the course uses a scripting language to reduce the language introduction overhead and encourage a practical, hands-on appreciation of OO.

Objective of the course:
- Explain the terminology of object-orientation
- Understand the principles and practices on which object-
- Become familiar with modern trends in OO development,
- development, design patterns, refactoring and object modelling
- Experience object-oriented programming first hand

Who Should Attend:
The course is suitable for software developers who wish to gain a practical understanding of OO programming. No prior knowledge of OO concepts or OO programming is assumed. However, experience of programming in a modern programming language is required — the course is an introduction to OO programming but not an introduction to programming.
