How can students write analytically?

Defining analytical writing

  • Analytical writing — a style of writing that moves beyond "what", "where" and "who" to explore "why", "how" and "so what"

  • It contrasts with descriptive writing — the presentation of research that simply provides background context or explains a theory without appraisal

  • Analytical writing is used to explore the significance and meaning of facts and ideas in depth

  • The goal of analysis is to break down a topic to understand its essential elements or structure

Strategies for effective analysis

  • Move beyond just providing facts by exploring relationships and patterns — logical connections between different pieces of information

  • Engage with research purposefully to develop and evidence an argument rather than just presenting findings

  • Apply subject—specific ideas or theories to a topic and evaluate their strengths and limitations

  • Identify specific characteristics in a text or data set and explain the significance or effects of those findings

  • Avoid a fragmented essay by ensuring that analysis is not just a general overview or a repetition of others' views

Using the PEELL structure

  • Students can ensure their writing is analytical by using PEELL — a structural technique for organising points within a paragraph

  • P (Point) — state the specific point being made

  • E (Evidence) — provide evidence such as a quotation, data or a summary to support the point

  • E (Explanation) — explain how the provided evidence supports the specific point

  • L (Link to RQ) — connect the point directly back to the Research Question (RQ)

  • L (Link to next point) — create a transition to the next stage of the argument to ensure the essay flows logically

Linking points to the Research Question

  • All analysis must be rooted in evidence and link back to the RQ — the focused question that directs the entire inquiry

  • Linking points back to the RQ helps build a coherent line of argument — a sustained thread of logical reasoning that runs through the essay

  • A strong line of argument acts as a map for the reader, helping them follow the logic behind your evidence and conclusions

  • Consistent linking prevents the reader from questioning how different parts of the essay fit together
