Building Robust Programs with Defensive Design

Slide 1 - Slide

This item has no instructions

Learning Objective
At the end of the lesson, you will be able to design and build robust software programs using defensive design principles.

Slide 2 - Slide

Introduce the learning objective and explain the importance of defensive design in software development.
What do you already know about software programming and defensive design?

Slide 3 - Mind map

This item has no instructions

What is Software Programming?
Software programming is the process of designing, writing, testing, and maintaining computer programs.

Slide 4 - Slide

Define software programming and explain its significance in the world of technology.
Why is Robustness Important?
Robustness is the ability of a program to handle unexpected inputs and situations. It is important because it ensures the program performs as expected and does not crash or produce incorrect results.

Slide 5 - Slide

Explain the importance of program robustness and provide examples of what can happen when a program is not robust.
Defensive Design Principles
Defensive design is a set of principles and practices that help ensure program robustness. These include input validation, error handling, and defensive coding.

Slide 6 - Slide

Introduce the principles of defensive design and provide a brief overview of each one.
Input Validation
Input validation is the process of checking user input to ensure that it is valid and meets certain criteria.

Slide 7 - Slide

Explain the importance of input validation and provide examples of how it can be implemented in a program.
Error Handling
Error handling is the process of dealing with errors that occur during program execution. This includes catching and handling exceptions, logging errors, and providing meaningful error messages to users.

Slide 8 - Slide

Explain the importance of error handling and provide examples of how it can be implemented in a program.
Defensive Coding
Defensive coding is the practice of writing code that is robust and resilient to unexpected inputs and situations. This includes using defensive programming techniques such as assertions and defensive comments.

Slide 9 - Slide

Introduce the concept of defensive coding and provide examples of how it can be implemented in a program.
Testing and Debugging
Testing and debugging are important parts of the software development process. Testing involves running a program to identify bugs and errors, while debugging involves finding and fixing those bugs and errors.

Slide 10 - Slide

Explain the importance of testing and debugging in the software development process and provide examples of testing and debugging techniques.
Code Reviews
Code reviews involve having other developers review your code to identify potential issues and provide feedback. Code reviews can help improve the quality and robustness of a program.

Slide 11 - Slide

Explain the importance of code reviews and provide examples of how they can be conducted.
Version Control
Version control is the process of tracking changes to a program over time. It allows developers to collaborate on a project and keep track of changes made to the code.

Slide 12 - Slide

Explain the importance of version control and provide examples of version control tools and techniques.
Secure Coding Practices
Secure coding practices involve writing code that is resistant to security threats such as hacking and malware. This includes using encryption, secure communication protocols, and input validation.

Slide 13 - Slide

Introduce the concept of secure coding and provide examples of secure coding practices that can be implemented in a program.
Common Programming Languages
There are many programming languages to choose from when developing software. Some common programming languages include Java, Python, C++, and JavaScript.

Slide 14 - Slide

Provide an overview of some common programming languages and their uses in software development.
Integrated Development Environments (IDEs)
IDEs are software applications that provide tools and features for developing, testing, and debugging programs. Some popular IDEs include Eclipse, Visual Studio, and PyCharm.

Slide 15 - Slide

Introduce the concept of IDEs and provide examples of popular IDEs that can be used for software development.
Conclusion
Defensive design is an important aspect of software development. By following the principles of defensive design and using appropriate tools and techniques, developers can create robust programs that are resistant to unexpected inputs and situations.

Slide 16 - Slide

Summarize the key points of the lesson and emphasize the importance of defensive design in software development.
Review Questions
1. What is software programming?
2. What is robustness and why is it important?
3. What are some principles of defensive design?
4. What is the difference between testing and debugging?
5. What is version control and why is it important?

Slide 17 - Slide

Provide review questions to test the students' understanding of the key concepts covered in the lesson.
Activity: Design a Robust Program
In groups, design a program that incorporates the principles of defensive design. Be prepared to present your program to the class.

Slide 18 - Slide

Provide instructions for the activity and allow time for students to work in groups.
Activity: Code Review
In pairs, review each other's code and provide feedback on how it could be improved to make it more robust.

Slide 19 - Slide

Provide instructions for the activity and allow time for students to work in pairs.
Activity: Debugging Challenge
In pairs, identify and fix the bugs in a provided program. The pair that identifies and fixes the most bugs in the fastest time wins.

Slide 20 - Slide

Provide instructions for the activity and allow time for students to work in pairs.

Slide 22 - Slide

Provide a list of references used in the lesson for students who want to learn more about the topics covered.
Write down 3 things you learned in this lesson.

Slide 23 - Open question

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.
Write down 2 things you want to know more about.

Slide 24 - Open question

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.
Ask 1 question about something you haven't quite understood yet.

Slide 25 - Open question

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
