Creativity, activity, service (CAS)
Creativity, activity, service (CAS) is at the heart of the DP.
With its holistic approach, CAS is designed to strengthen and extend students’ personal and interpersonal learning.
Creativity—exploring and extending ideas leading to an original or interpretive product or performance.
Activity—physical exertion contributing to a healthy lifestyle.
Service—collaborative and reciprocal engagement with the community in response to an authentic need.
CAS aims to develop students who: enjoy and find significance in a range of CAS experiences, purposefully reflect upon their experiences, identify goals and understand they are members of local and global communities with responsibilities towards each other and the environment.
A CAS experience is a specific event in which the student engages with one or more of the three CAS strands. It can be a single event or an extended series of events. A CAS project is a collaborative series of sequential CAS experiences lasting at least one month.
Typically, a student’s CAS programme combines planned/unplanned singular and ongoing experiences. All are valuable and may lead to personal development. However, a meaningful CAS programme must be more than just a series of unplanned/singular experiences.
The extended essay (EE)
The extended essay is a compulsory, externally assessed piece of independent research into a topic chosen by the student and presented as a formal piece of academic writing. The extended essay is intended to promote high-level research and writing skills, intellectual discovery and creativity while engaging students in personal research.
This leads to a major piece of formally presented, structured writing of up to 4,000 words in which ideas and findings are communicated in a reasoned, coherent and appropriate manner. Students are guided through the process of research and writing by an assigned supervisor (a teacher in the school). All students undertake three mandatory reflection sessions with their supervisor, including a short interview, or viva voce, following the completion of the extended essay.
Extended essay topics may be chosen from a list of approved DP subjects—normally one of the student’s six chosen subjects for the IB diploma or the World Studies option. World Studies provides students with the opportunity to carry out an in-depth interdisciplinary study of an issue of contemporary global significance, using two IB disciplines.
Theory of knowledge (TOK)
The theory of knowledge (TOK) course plays a special role in the DP by providing an opportunity for students to reflect on the nature, scope and limitations of knowledge and the process of knowing.
In this way, the main focus of TOK is not on students acquiring new knowledge but on helping students to reflect on, and put into perspective, what they already know. TOK underpins and helps to unite the subjects that students encounter in the rest of their DP studies.
It engages students in explicit reflection on how knowledge is arrived at in different disciplines and areas of knowledge, on what these areas have in common and the differences between them.
The TOK course is assessed through an exhibition and a 1,600 word essay.
The exhibition requires the students to create an exhibition of three objects that explores how TOK manifests in the world around us.
The essay focuses on a conceptual issue in TOK. For example, it may ask students to discuss the claim that the methodologies used to produce knowledge depend on the use to which that knowledge will be used.
