Core Content Instruction (20 minutes)

11.1 What is Source Acknowledgment? (10 minutes)

Definition (CRD-2.H.1):

Source acknowledgment is the practice of crediting the resources used in program development.

Key Concepts:

• Code sources: Libraries, APIs, frameworks
• Design sources: UI/UX inspiration, design patterns
• Content sources: Images, text, data
• Collaboration sources: Team members, mentors, users

Case Study: The development of an open-source project

• Acknowledgment process: Crediting libraries, contributors, and users
• Outcome: A credible and transparent open-source project

11.2 Types of Sources (5 minutes)

Types:

• **Code sources: Libraries, APIs, frameworks
• **Design sources: UI/UX inspiration, design patterns
• **Content sources: Images, text, data
• **Collaboration sources: Team members, mentors, users

Examples:

• E-commerce app: Code sources - payment libraries; Design sources - user interface patterns
• Social media app: Code sources - social API integrations; Content sources - user-generated content

11.3 Importance of Source Acknowledgment (5 minutes)

Why is it important?:

• Credibility: Acknowledges contributions to the program
• Transparency: Shows what resources were used
• Ethics: Avoids plagiarism and ensures proper credit
• Collaboration: Encourages sharing and reuse

Discussion Questions:

1. How does source acknowledgment improve program credibility?
2. What are the different types of sources in computing?
3. Why is source acknowledgment important for successful programs?
