If you are formulating your own Knowledge Issues for a presentation, you might consider phrasing the question in terms of Theory of Knowledge concepts and vocabulary (words in bold).
Beginning the question, “How can we know?” or putting the word “knowledge” in the question. For example, “Is our knowledge in maths actually more certain than our knowledge in science?”
More imaginative ways might include, “How far is it justified…?” or “Is the evidence for x compelling… and on what reasonable grounds? Or, “Which interpretation is more compelling….x or y”, or, “Is the assumption that x well founded?”
TOK vocabulary includes all of the following words and more: knowledge, justification, interpretation, judgement, evidence, theory, explanation, coherence, assumptions, implications, reason, emotion, sense perception, language and paradigm.”
An unsuitable choice for a presentation would be, “Should there be freedom of speech?” This is too general and not focussed enough on TOK. You need to focus on knowledge. A better KI might be more precise and couched in TOK vocab. For example, “What part might reason, emotion and language play in our interpretation of historical and contemporary events?”
For your real life example you could choose the media coverage of the abduction of girls in Nigeria. For more on the story:
