IB Computer Science | Syllabus, Notes & Past Papers

The IB Computer Science course in the IB Diploma Programme is a challenging and hands-on discipline focused on real-world problem-solving. Students explore how computer science shapes and impacts cultures, societies and individual behaviour, while also addressing the ethical issues that arise in the digital age.

Throughout the IB Computer Science syllabus, learners develop computation solutions by identifying problems, designing prototypes, and creating effective models. They analyze and evaluate these models, predict their success, and recommend improvements for future developments. This process involves:

 

1. Identifying a problem or unanswered question
2. Desiging, prototyping and testing a proposed solution
3. Engaging with clients to assess success and suggest future enhancements.

 

The curriculum emphasizes core principles of computational logic and builds understanding of how computers and other electronic devices function. As an evolving field, IB Computer Science demands mastery of multiple programming languages and continuous innovation.

For effective preparation, students can benefit from IB Computer Science notes for quick revision and use past papers to practice exam style questions. Personalized IB online academic tutoring can further strengthen understanding and boost performance. 

 

Understanding IB DP Computer Science from scratch

 

The International Baccalaureate describes the IB Computer Science in Diploma Programme as a rigorous problem-solving course. The IB Computer Science syllabus is offered at two levels: Standard and Higher, with the following features and benefits to students:

• Learning programming skills applicable to almost all fields of study
• Assessments for the development of computational and algorithmic thinking
• Encourage students to conduct in-depth research on current issues that are not covered in their curriculum.

 

In general, the following core topics are covered in both IB Computer Science SL and HL:

 

• Fundamentals of the system
• Computer administration
• Networks
• Problem-solving, computational thinking, and programming

 

The following additional topics are covered in HL extension:

 

• Data structures that are abstract
• Control over resources

 

IB Computer Science IA: Everything you Need to Know

 

In IB Computer Science, students must showcase the practical application of their skills through the Internal Assessment (IA). This involves designing and developing a functional product along with comprehensive documentation detailing the solution. The IA is evaluated out of 34 marks and plays important role in final grade- accounting for 30% of total grade for Computer Science SL and 20% for Computer Science HL.

According to syllabus, the IA has a strict word limit of 2,000 words, excluding the bibliography, footnotes and appendices. Completing this assessment successfully requires integrating technical expertise, problem- solving ability, and clear communication- making it a vital component of curriculum.

 

Your Computer Science IA includes the following components:

 

• A title page
• The fully functional item
• Documentation, including a 7-minute video

 

In total, five criteria are evaluated, each of which addresses a different aspect of your investigation. The IB’s five criteria are as follows:

 

• Planning
• Overview of the Solution
• Development
• Product functionality and extensibility
• Evaluation

 

How to Know they’re the One: Finding the Right Client for your Computer Science IA

 

This is possibly the most crucial stage of your IA process. It’s always a good idea to approach your parents, teachers, or relatives first. However, an acquaintance or a business owner, for example, can be approached.

 

• Make sure you understand your client’s needs and consider how you can help them.
• Before you begin working, discuss the work criteria and obtain consent for the personal use of data.
• Maintain confidentiality where necessary and be accountable for sensitive data and information.
• Plan at least two meetings with your client. The first is to assess the product’s need and feasibility, and the second is to consult with the client on the rationale and success criteria you devise. You are only supposed to proceed if they give you approval on the final product’s success criteria. The transcripts of the interviews must be attached as an appendix and referenced in the main text.
  After delivering your solution to the client, solicit feedback and have it evaluated.
• It’s possible that becoming a client for your own IA isn’t the best idea. Also, remember to discuss all of your options with your advisor before deciding on one.

 

The Computer Science IA Topic Hunt

 

Your IB Computer Science IA topic should be of sufficient complexity to demonstrate your algorithmic and organisational thinking. Your work should demonstrate your computational thinking skills. The topic does not have to be related to your syllabus, and you are free to choose a programming language if you can justify its use. According to the IB, your solution could take the form of:

 

• Developing a new system, such as an object-oriented programme, a relational database, a simulation, or a standalone/web-based application
• Adding functionality to an existing system, such as connecting a webpage(s) to a database, writing a Moodle function, creating a plug-in, or creating a stand-alone application

 

Frequently Asked Questions
