Introduction to computer science

ICS3U introduces students to the foundational concepts of computer science through structured programming and algorithmic problem-solving. Students develop computational thinking skills and gain practical experience in designing and coding computer programs.

The course also explores societal and ethical issues related to computing, making it an ideal introduction to the field of software development and digital innovation.

Unit 1: Software Development and Programming Fundamentals
Students are introduced to the basics of programming and the software development life cycle.
Lessons include:

• Introduction to Programming and Algorithms
• Understanding Syntax and Variables
• Data Types and Control Structures
• Input/Output Operations
• Writing and Testing Simple Programs

Unit 2: Problem Solving and Computational Thinking
This unit emphasizes critical thinking and algorithm design.
Lessons include:

• Developing Logical Thinking
• Using Flowcharts and Pseudocode
• Loops, Conditions, and Functions
• Debugging and Troubleshooting
• Modular Programming

Unit 3: Object-Oriented Programming
Students explore more advanced programming concepts through object-oriented design.
Lessons include:

• Introduction to Classes and Objects
• Attributes and Methods
• Inheritance and Encapsulation
• Object Interaction and Data Management
• Building Object-Oriented Applications

Unit 4: Ethics, Careers, and Applications in Computer Science
This unit looks beyond coding into the impact of computer science in real-world contexts.
Lessons include:

• Ethical and Legal Issues in Computing
• Technology and Society
• Emerging Trends in CS (AI, Cybersecurity, Big Data)
• Career Pathways in Tech
• Final Project Proposal and Development

• 70% of the final grade is based on coursework, including:
  • Coding assignments, debugging tasks, and logic puzzles
  • Projects involving game development, simple apps, or data processing
  • Quizzes, reflections, and peer code reviews
• 30% of the final grade is based on final evaluations:
  • 10% Culminating software development project
  • 20% Final written and/or practical exam assessing programming proficiency and theoretical understanding

All assessments follow Ontario curriculum standards and are designed to build foundational programming, logical reasoning, and analytical skills for success in STEM disciplines.
