Communication in Global Perspectives & Research (9239)
Why this matters for the exam – Mastering communication helps you meet the three Assessment Objectives (AO) that are weighted across the written exam, essay and research‑report components:
AO3 – Communication (35 %): present ideas clearly, use discipline‑specific terminology and reference accurately.
1. Core Communication Concepts (with AO1 link)
Concept
Definition
Message
The idea, claim or information that the sender wishes to convey.
Sender / Encoder
The individual or group who creates and packages the message. Identifying the sender is part of AO1 – it tells you whose perspective is being presented.
Receiver / Decoder
The audience that interprets the message, bringing their own knowledge and cultural background.
Channel
The medium (essay, slide‑deck, digital platform, etc.) through which the message travels.
Noise
Any factor that distorts meaning – semantic (ambiguous words), cultural (different values), technical (poor formatting) or environmental (distractions).
Feedback
The response from the receiver that can lead to revision, clarification or further development of the argument.
Exam tip (AO1‑AO3): When analysing a source, explicitly note the sender, channel and possible noise. This demonstrates AO1 (analysis) and lays the groundwork for a clear AO3 presentation.
2. Communication Models & AO Mapping
Model
Key Features
Relevance to Written Arguments
Targeted AO(s)
Linear Model (Shannon & Weaver)
Sender → Channel → Receiver; includes noise.
Emphasises precise language and logical sequencing to reduce noise.
AO1, AO3
Interactive Model
Introduces feedback loops and context.
Highlights the role of peer review, drafts and revision in strengthening arguments.
AO2, AO3
Transactional Model
Simultaneous encoding/decoding within a shared field; meaning is co‑constructed.
Supports collaborative research, team presentations and the ethical need to represent diverse perspectives.
AO2, AO3
3. Critical Path – Where Communication Fits
The Cambridge syllabus organises the research process into four interlinked stages. Communication is the final stage, but it is informed by the three preceding stages.
Deconstruction
Break down the issue into key concepts, stakeholders and underlying assumptions.
Key questions: What is the central claim? Who is affected? Which global theme does it relate to?
Reconstruction
Develop a new perspective, select appropriate evidence and plan a logical argument.
Key questions: What thesis will I adopt? Which evidence best supports it?
Reflection
Critically evaluate the reliability, bias and ethical implications of each source (RAV checklist).
Key questions: Is the source reliable? Who produced it and why?
Communication
Present the reconstructed argument using discipline‑specific terminology, visual aids and accurate referencing.
Link to AOs: Deconstruction and Reflection develop AO1 & AO2; Reconstruction and Communication demonstrate AO2 & AO3.
4. Example Global Topics (sidebar)
Use the communication framework with any of the following topics (or any other approved global issue):
Climate change and sustainable development
Human rights and social justice
Digital technology and its impact on society
Health inequalities and pandemics
Each topic requires you to identify stakeholders, analyse evidence, consider ethical dimensions and communicate a balanced argument.
5. Structure of a Structured Written Argument
Introduction
Brief context – why the issue matters globally.
Clear research question or thesis statement.
Road‑map – outline the logical route (e.g., “First I will examine…, then I will…”).
Body Paragraphs (repeat for each main point)
Topic sentence – directly links back to the thesis.
Evidence – data, quotations, case studies; always accompanied by an in‑text citation.
Analysis – explain in plain language how the evidence supports the claim (AO3).
Counter‑argument – acknowledge a credible alternative view.
Rebuttal – use further evidence or reasoning to show why the original claim remains stronger.
Conclusion
Summarise the main findings without introducing new evidence.
Restate the thesis in light of the analysis.
Suggest wider implications, policy recommendations or areas for further research.
Linking words (AO3): however, therefore, consequently, moreover, on the other hand, in contrast, thus.
Accurate referencing avoids plagiarism, allows verification of evidence and contributes to AO3. Cambridge accepts Harvard, APA and MLA; the examples below use Harvard.
Author(s) (Year) ‘Title of article’, Journal Name, volume(issue), pages.
Online source
(Organisation, Year) – e.g., (UNESCO, 2022)
Organisation (Year) ‘Title’, Website. Available at: URL (Accessed: Day Month Year).
Note: If you prefer APA or MLA, follow the Cambridge guidelines for formatting; the underlying principle of consistency remains the same.
8. Research‑Method Reminder (A‑Level only)
Primary vs. secondary sources: Primary data are collected first‑hand (surveys, interviews); secondary data are analysed by others (reports, journal articles).
RAV checklist for every source:
Reliability – Is the information consistent over time?
Authority – Who produced it and what are their credentials?
Validity – Does it measure what it claims to?
Sampling & bias – note sample size, selection method and any potential bias.
9. Ethical Considerations & Authenticity
Bias & representation – ensure all relevant stakeholder groups are fairly portrayed.
Data protection – anonymise personal data unless explicit consent is given.
Responsible use of visuals – avoid misleading graphs or selective cropping.
Plagiarism – always cite, even when paraphrasing.
Declaration of authenticity – every coursework component (essay, report, presentation) must include a signed statement that the work is your own.
AO2 link: Evaluating the ethical dimensions of a source is a core part of the “critical analysis” skill set.
10. Visual Communication (charts, infographics, tables)
Visuals are part of AO3 for the research report and the team presentation. They should be:
Relevant – directly support a claim made in the text.
Clear – labelled axes, units and a concise caption.
Accurately sourced – include a reference beneath the visual.
Accessible – use colour‑blind‑friendly palettes and simple layouts.
13. Example Argument (with plain‑language explanation)
Research Question: To what extent does social media influence political participation among young adults?
Thesis statement: Social media significantly enhances political participation among young adults by providing platforms for information dissemination, mobilising collective action, and fostering political identity.
Body excerpt
Recent surveys indicate that 68 % of 18‑24‑year‑olds use social media as their primary news source (Pew Research Centre, 2023). This high exposure correlates with increased voter turnout, as shown by the regression analysis below:
Plain‑language interpretation (AO3): The coefficient β₁ = 0.42** means that, on average, a one‑unit increase in social‑media use (e.g., moving from “rarely” to “often”) is associated with a 0.42‑point rise in a voter‑turnout score. The p‑value p < 0.01 tells us this relationship is statistically significant – it is very unlikely to have arisen by chance.
Counter‑argument: Critics claim that echo chambers on social platforms can polarise opinions, reducing constructive participation (Sunstein, 2018).
Rebuttal: Longitudinal studies, however, show that platforms with algorithmic transparency and diverse‑content feeds mitigate polarisation (Garcia & Lee, 2021). Moreover, participants who deliberately follow opposing viewpoints report higher levels of political efficacy.

14. Assessment Tips (AO‑focused)
Skill
How to develop it
Linked AO
Planning (mind‑maps, outlines)
Allocate 10 % of your time to sketching the argument structure before writing.
AO1, AO2
Single‑claim paragraphs
Start each paragraph with a topic sentence, then add evidence, analysis, counter‑argument and rebuttal.
AO2, AO3
Integrating evidence seamlessly
Use signal phrases (“According to…”, “Data from… show that…”) and embed citations naturally.
AO1, AO3
Evaluating sources for reliability & bias
Apply the RAV (Reliability, Authority, Validity) checklist to every source.
AO2
Proofreading for coherence & referencing
Read aloud, check linking words, and verify every in‑text citation has a matching reference‑list entry.
AO3
Using visual aids responsibly
Design a simple bar chart with clear labels; cite the data source directly beneath the figure.
AO3 (research report & presentation)
15. Summary
Effective communication in Global Perspectives requires:
Clear understanding of core concepts and models, linked to AO1‑AO3.
Strategic placement of communication within the Critical Path (Deconstruction → Reconstruction → Reflection → Communication).
Structured arguments that integrate evidence, counter‑arguments and rebuttals.
Consistent use of discipline‑specific terminology and ethical awareness (including plagiarism and the declaration of authenticity).
Accurate referencing (Harvard, APA or MLA) and, where appropriate, well‑designed visual aids.
Specific attention to the technical requirements of Component 3 (presentation) and Component 4 (research report).
Following this framework will enable you to construct persuasive, well‑referenced written arguments that meet the demands of the Cambridge A‑Level Global Perspectives & Research assessment.
