Quick answer

The current Language B course has five prescribed themes: identities, experiences, human ingenuity, social organization and sharing the planet. They organize communication across contexts; they are not a closed list of exam questions or vocabulary. Learn words through short authentic texts, then use them in a spoken explanation and a written response for a specific audience.

What the five themes are for

The IB organizes Language B around five prescribed themes. They help teachers and students explore language in varied social and cultural contexts. The IB also provides optional suggested topics, but those suggestions are not prescribed exam questions. Do not treat an online topic list as a prediction of what will appear in your paper.

A useful theme study session ends with something you can say or write, not only a translated word list. Choose an authentic short text, identify the author's view, collect a few reusable expressions and respond from your own perspective. The same routine supports reading, writing and the oral.

The five prescribed Language B themes and original practice prompts
ThemeOne practice question
IdentitiesHow does a language affect someone's sense of belonging?
ExperiencesWhat changes when students study in a different community?
Human ingenuityWhen does a new tool improve learning?
Social organizationHow should a school decide a shared rule?
Sharing the planetWhat local action could reduce waste?

Identities and experiences: move past vague opinions

Identities can include language, belonging and how people present themselves. Experiences can include learning, travel and events that change a perspective. These are examples, not a complete official topic list. Use a real text to notice whose voice is present and whose is missing.

Replace broad statements such as 'culture is important' with a specific explanation. You might compare two ways a new student is welcomed, then explain the effect on belonging. That gives you useful verbs—adapt, include, misunderstand, connect—in sentences with meaning. It also prepares you to answer a follow-up question rather than recite definitions.

Human ingenuity and social organization: explain consequences

Human ingenuity opens discussions about invention, media and creative choices. Social organization concerns the ways groups make decisions and live together. A school technology policy can connect both themes. The useful language is often relational: benefit, limitation, access, responsibility, consequence and trade-off.

Practise stating a claim, giving one example and acknowledging a limitation. For instance: 'A translation tool can help newcomers understand instructions, but students still need chances to practise speaking.' The sentence is more useful than memorizing an isolated phrase such as 'technology is good'.

Sharing the planet: make solutions concrete

Environmental topics often invite general claims. To make your answer stronger, choose a scale: your classroom, school, neighbourhood or a wider community. Say what action is possible, who would carry it out and how you would judge whether it worked.

An original practice task might ask a student council to reduce cafeteria waste. That can become a Paper 1 email proposal, a Paper 2 reading topic or an SL oral discussion from a suitable visual. The language changes with the task, but the core ideas can transfer.

A four-step vocabulary cycle

Pick five to eight expressions from a text you understand mostly without a dictionary. Record the whole phrase and a short example, not only a single translated word. The next day, explain the text aloud using those phrases. Later in the week, use two or three in a short response for a named reader. Review after several days and remove words you still cannot use accurately.

Group phrases by what they help you do: compare, qualify, disagree politely, give evidence or suggest action. This makes retrieval easier in a Paper 1 response or oral discussion. For writing form choices, use the Paper 1 guide.

  • Read or listen in context
  • Save a short phrase and its meaning
  • Say one original sentence
  • Write for a specific reader
  • Revisit and correct the phrase

Keep the language habit small enough to repeat

Nektar's available General English tools can support regular reading and vocabulary work. Use the five official themes to choose what you read and discuss with your teacher; do not treat app content as an IB syllabus or question bank.

Nektar currently shows only a disabled English B preview for eligible students. IB-specific lessons, question sets and assessments are not available in the app. Its available General English tools can support underlying language practice; use your school and official IB material for exam-specific work.
