Summary, Terminology and Practice (DP IB Theory of Knowledge): Revision Note
Summary
Here we will summarise the main ideas covered in the optional theme “Knowledge and Language”
TOK element | Content summary | Example | Possible knowledge questions |
|---|---|---|---|
Scope | Language expands the scope of knowledge because it allows ideas to be stored, shared, and built on over time. It makes complex ideas easier to think about by giving us categories for organising experience However, it can also limit scope when a community lacks precise words for a concept, making it harder to notice or communicate Translation can widen scope by bridging communities and increasing access, but it can also reduce scope when nuance and associations do not transfer cleanly, or when concepts depend heavily on cultural context | 1) In school, the term “bullying” gives a clear label for a pattern of harmful behaviour. This makes it easier to recognise repeated incidents and apply agreed policies. Without the shared label, the same behaviour may be dismissed, making it harder to identify and respond to 2) Translating the Danish word “hygge” as “cosiness” gives outsiders access to the idea but narrows it by losing cultural nuance and the wider associations the original term carries | How does having words and categories affect what a community can easily know or communicate? If language represents reality rather than copying it, how does that shape the scope of what can be expressed or understood? To what extent does translation widen access to knowledge versus changing the knowledge itself? |
Perspectives | An individual’s pre-held perspectives might influence whether or not they understand the connotations of a particular term or they have emotional responses to a metaphor The same word or label can signal status or disapproval depending on a person’s background, and labels can shape expectations about individuals or groups | 1) Two parents hear a teacher describe a child as “lively”. One parent is already worried about discipline and hears it as a warning sign; another, who values spontaneity, hears it as praise 2) A student who already sees themselves as “bad at maths” interprets the label “foundation set” as confirmation they will not improve, while another student sees it as a practical starting point and focuses on progress | How do pre-existing cultural values and experiences shape how we interpret connotations and tone? How do metaphors (e.g. calling immigration a “flood” or an economy “healthy/sick”) channel attention toward some interpretations before evidence is considered? When different groups use different conceptual schemes, how can they reach shared understanding? |
Methods and tools | Methods in language-based knowledge include interpreting, defining terms to reduce ambiguity, and translating meaning for new audiences The main tool is language itself (shared vocabulary, grammar, and conventions), supported by tools like disciplinary terminology, glossaries, and translation resources These methods and tools can strengthen knowledge by improving precision and shared understanding, but they can also introduce errors when meanings shift, ambiguity is ignored, or translation choices lose nuance or create misleading “equivalents” | 1) In a class debate, students realise they are using the word “theory” differently; agreeing on a definition changes how they evaluate the claim 2) A translated news headline uses a near-equivalent word that carries a stronger negative tone in English, so the audience interprets the original event more harshly than intended | Why do definitions and specialist terminology improve precision, and when do they exclude non-specialists? In translation, what matters most for knowledge: literal wording, equivalent meaning, or the effect on the audience? |
Ethics | Persuasion becomes ethically problematic when it manipulates rather than informs, e.g. through propaganda or euphemisms that hide harm or responsibility Ethical communication prioritises clarity, accuracy and transparency so audiences can judge claims autonomously Language also links to power: linguistic inequality (e.g. due to accent, dialect or fluency) can restrict whose knowledge is heard, whose testimony is trusted, and who can access essential information | 1) A company’s press release states that a product failure “resulted in an adverse outcome” instead of stating that it harmed customers; the wording downplays responsibility and limits the audience’s ability to judge the situation, raising ethical concerns about accountability 2) In a hospital, important consent information is only provided in English; non-fluent patients may misunderstand risks and have less genuine choice | When does persuasive language cross the line into manipulation? What ethical duties do speakers/writers have to be clear and transparent, and in what contexts? How does linguistic inequality affect whose knowledge is trusted and whose voices are marginalised? |
Terminology
Key terminology | Definition |
|---|---|
Connotation | The associated meaning of a word, beyond its dictionary definition (denotation) |
Linguistic determinism | The theory that the language we use determines how we think and how we perceive the world |
Code switching | Changing the style, accent tone of language in keeping with the context, e.g. speaking standard English in the workplace and switching to a local dialect in the home |
Linguistic imperialism | The dominance of one language over another, usually reinforced by power dynamics |
Culturally specific terms | Words or phrases that hold specific meaning in some cultures and not in others. Their usage can raise questions of ownership and ethics |
Practice
Worked Example
Make a list of 15 new words you have learned since starting the IBDP (e.g. terminology in your Group 3 or 4 subjects)
How difficult was it to learn these new words? What helped you learn them?
How important was it to learn these new words? What do you gain by knowing them, e.g. precision, clarity, understanding, meeting marking criteria in assessments?
If you are studying the DP in a language that is not your mother tongue, do you translate these terms into your mother tongue? Is this difficult to do? Is anything lost in the meaning when you translate them?
What is the relationship between these terms and knowledge in the subject in which they occur? Consider, for example, classification, connotation, power, euphemism, logic, order, sharability
