Lesson: Essay Writing (Strand 2: Writing)
Hello, Upper Secondary students! Have you ever been told to "write an essay" and suddenly felt completely blank, not knowing how to craft your first sentence, or felt like your ideas were just going in circles after writing for a bit? If it feels tricky at first, don't worry! Essay writing isn't just about raw talent—it's a "skill" built on clear structures and defined steps. Once you grasp the core concepts and understand the structure, expressing your ideas through the written word will definitely become much more fun and effortless.
(Note: Essay writing is one of the foundational written forms under Strand 2: Writing. Specific discourse modes and techniques—such as exposition, narration, description, expressing viewpoints, argumentation, or academic report writing—are covered in detail in separate lessons within this same strand.)
1. What is an Essay?
An essay is a form of prose writing in which the author systematically organizes their thoughts, knowledge, experiences, or feelings regarding a specific subject. It is driven by clear aims, well-supported information, and a central theme, focusing on organizing ideas to communicate effectively, accurately, and elegantly with the reader.
A Helpful Analogy: Think of an essay as "a train journey." The locomotive leads the way, navigates the track, and draws in the passengers (Introduction); each passenger carriage transports content, evidence, and key points in a smooth sequence (Body); and the destination station is where the train halts, leaving passengers with a lasting impression and a complete understanding (Conclusion).
2. The Three Core Elements of an Essay
Every standard essay, regardless of its length, must always consist of three main parts:
Part 1: Introduction
The introduction is the very first paragraph of your essay. It serves to introduce the topic, provide context, outline the scope of the content, and, most importantly, "hook the reader's interest so they want to read on."
• Consists of only 1 paragraph.
• Proportional length is roughly 10% – 15% of the total essay length.
• Techniques for an engaging hook: For instance, citing a relevant proverb, idiom, or quote; posing a thought-provoking question; referencing a current event or an intriguing fact; or sharing a brief narrative that bridges directly into the central thesis.
Part 2: Body
The body is the longest section of the essay. Its role is to explain and expand on concepts, information, supporting reasons, examples, or evidence to reinforce the main points introduced at the start.
• Can contain multiple paragraphs (typically 2–4 paragraphs for Upper Secondary level, depending on the subtopics).
• Proportional length is roughly 70% – 80% of the total essay length.
• Golden Rule for Body Paragraphs: Each paragraph must contain only "one central main idea," followed by supporting reasons, factual evidence, or illustrative examples.
Part 3: Conclusion
The conclusion is the final paragraph of the essay. It serves to wrap up the discussion, reinforce the core thesis, and leave the reader with a memorable insight or takeaway.
• Consists of only 1 paragraph.
• Proportional length is roughly 10% – 15% of the total essay length.
• Techniques for concluding effectively: For instance, concisely restating the key arguments, offering a final reflection or moral insight, asking an open-ended question that stimulates further thought, or ending with an impactful poetic verse or quotation.
Did you know? A strong introduction should avoid phrases like "In this article, I will talk about..." or "Today, I am going to write about..." because they make your essay sound like a casual personal diary rather than an academic piece of writing. Opening with a sharp insight or a compelling question is far more effective at captivating your reader!
3. Three Pillars of an Excellent Essay (Unity, Coherence, Emphasis)
A great essay isn't just about using fancy vocabulary or making it as long as possible; it must adhere to three foundational linguistic and structural principles:
1) Unity (เอกภาพ): Singleness of Purpose
Every section of the essay—the introduction, every body paragraph, and the conclusion—must stay focused on "the same central purpose and topic." Avoid straying off-topic or inserting irrelevant tangents.
2) Coherence (สัมพันธภาพ): Seamless Connection
Sentences and paragraphs must flow together logically and smoothly. Use effective transitional words and discourse markers (such as therefore, furthermore, on the other hand, ultimately) to guide the reader's eyes and thoughts naturally from one point to the next.
3) Emphasis (สารัตถภาพ): Highlighting the Core Points
The main ideas of the essay and of each paragraph must stand out prominently. It should be obvious what is a major point and what is supporting detail. Emphasize key ideas through strategic placement (such as at the beginning or end of a paragraph) and by dedicating appropriate depth to main points over minor details.
4. Steps in Writing an Essay: 3 Steps to Success
Step 1: Pre-writing & Outlining
This is the most critical stage—much like drafting a blueprint before constructing a building:
• Analyze the topic and objective: Read the prompt thoroughly to understand its core purpose and identify your target audience.
• Gather information: Brainstorm ideas, research relevant facts, or compile supporting evidence.
• Outlining: Categorize your ideas. Decide how the introduction will open, how many subtopics (train carriages) the body will contain, what supporting details belong in each, and how the conclusion will close. Outlining prevents you from wandering off-topic.
Step 2: Drafting
• Write according to your outline, choosing precise vocabulary that matches the appropriate register and conveys your intended meaning directly.
• Apply suitable rhetorical modes and stylistic devices to make your writing fluid and impactful.
• During this stage, focus primarily on expressing your thoughts fully in line with the planned structure.
Step 3: Revising & Editing
Once your draft is complete, read it over to refine it, checking:
• Content: Are all 3 core elements present? Does the piece demonstrate unity, coherence, and emphasis?
• Language mechanics: Check for spelling, spacing, punctuation, transitions, and maintain a consistent stylistic register.
5. Common Pitfalls in Essay Writing
Common mistakes that often cost students marks without them realizing include:
• Lacking unity (drifting off-topic): Adding random thoughts as they come to mind, causing the content to diverge from the main prompt.
• Lacking coherence (abrupt jumps): Paragraph 2 discusses one concept, but Paragraph 3 suddenly switches to another without transitions or logical bridges, creating a disjointed read.
• Multiple paragraphs for the introduction or conclusion: Always remember: the introduction is only 1 paragraph, and the conclusion is only 1 paragraph.
• Introducing brand-new points in the conclusion: The conclusion is meant for synthesis and closure. Never introduce brand-new arguments, data, or subtopics that were not addressed in the body paragraphs.
• Overly dense paragraphs or missing paragraph breaks: Writing the entire body as a single massive block of text, or cramming multiple distinct main ideas into one paragraph until it becomes confusing.
6. Etiquette in Writing (Standard Th 2.1 Indicators)
Being a skilled writer is not just about using eloquent language; it also requires practicing "writing etiquette," which includes the following principles:
• Responsibility and Integrity: Never plagiarize others' work or ideas. If you use external facts, statistics, or theories, properly cite and credit the original sources.
• Linguistic Accuracy: Ensure correct spelling, tone markers, and punctuation. Keep the presentation neat, clean, and legible.
• Constructive and Polite Expression: Avoid vulgarities, sarcasm, discriminatory or derogatory remarks, and language that incites social discord.
Key Takeaways
Key Takeaways summarizing the heart of essay writing:
• 3 Core Elements: Introduction (1 paragraph: hooks reader, introduces topic) + Body (multiple paragraphs: 1 main idea each, supported by reasons/examples) + Conclusion (1 paragraph: closes the piece, reinforces thesis, introduces no new ideas).
• 3 Pillars of Quality: Unity (focused on one single theme), Coherence (logically linked with smooth transitions), Emphasis (prominent, well-highlighted main points).
• 3-Step Process: Pre-writing & Outlining \(\rightarrow\) Drafting \(\rightarrow\) Revising & Editing.
• Etiquette: Maintain academic honesty, avoid plagiarism, write accurately and politely, and take responsibility for your words.
