Introduction to Queues Instructional Document

Learning Objectives

1. Explain Queue Fundamentals – Define FIFO (First-In-First-Out) ordering and real-world use cases (e.g., print jobs).

2. Implement a Queue in Java – Use the Queue interface with a LinkedList implementation.

3. Understand Runtime Performance – Compare operations in ArrayList vs. LinkedList and explain why Queue operations are O(1).

4. Apply Queue Operations – Add, remove, and iterate through elements using Java’s built-in methods.

Instructional Design Highlights

• Relatable Analogy: Connects abstract FIFO principles to everyday examples (e.g., waiting in line, print queues).

• Scaffolding: Begins with real-world context → abstract concept → code implementation → runtime analysis.

• Hands-On Code: Includes PrintJob and PrintManager class examples to demonstrate add/remove operations.

• Critical Thinking: Compares ArrayList vs. LinkedList performance, reinforcing why certain data structures are chosen.

• Clarity & Engagement: Conversational tone, humor, and analogies make technical content accessible to adult learners.

Assessment & Measurement

• Guided Reading Questions: Students explain FIFO ordering and runtime implications.

• Applied Practice: Students implement a Java Queue, add/remove items, and iterate over the collection.

• Code Review: Submitted Queue implementations checked for correctness and efficiency (Note: Code samples not included to maintain academic integrity.)
