Helping Students to Add Depth in High School Essay Writing:
Why Commentary Depth Matters in Essays
Many students struggle with commentary because they treat it as a simple restatement of evidence or a brief opinion. Commentary is more than that. It connects evidence to the thesis, explains significance, and shows critical thinking. Without strong commentary, essays become a list of facts rather than a persuasive argument.
Balanced evidence and commentary create a clear, convincing essay. Evidence provides the facts or examples, while commentary interprets those facts and explains their relevance. When commentary is shallow or missing, readers don’t understand why the evidence matters.
Teaching students to expand their commentary helps them:
Develop stronger arguments
Show deeper understanding of the text or topic
Engage readers with clear explanations
Avoid summary-only writing
The goal is to move beyond surface-level comments and build layers of explanation that reveal insight.
Understanding Evidence Balance
Evidence balance means using enough evidence to support claims without overwhelming the essay or leaving commentary underdeveloped. Students often make two common mistakes:
Too much evidence, too little commentary: This creates a “data dump” where facts pile up but lack explanation.
Too little evidence, too much commentary: This leads to unsupported opinions that feel weak or unconvincing.
A balanced paragraph typically includes:
A clear topic sentence
One or two pieces of evidence (quotes, facts, examples)
Several sentences of commentary that explain and analyze the evidence
Teaching students to find this balance improves clarity and persuasiveness.
Exercises to Expand Commentary
Here are practical exercises to help students practice expanding their commentary and layering explanations.
1. The “Why It Matters” Drill
After students write a piece of evidence, ask them to answer: Why does this evidence matter?
Have them write at least two sentences explaining the significance.
Encourage them to connect the evidence to the thesis or main argument.
Push for specific, not vague, explanations.
Example:
Evidence: “The protagonist’s refusal to conform shows her independence.”
Basic commentary: “This shows she is independent.”
Expanded commentary: “This refusal highlights her strength and sets up the central conflict between individuality and societal pressure, which drives the story’s theme.”
2. Layering Explanation with “So What?” Questions
Teach students to ask “So what?” repeatedly to deepen their commentary. Each answer should add a new layer of insight.
Start with a simple commentary sentence.
Ask “So what?” to push for a deeper explanation.
Repeat 2-3 times to build layers.
Example:
Commentary: “The author uses dark imagery.”
So what? “Dark imagery creates a mood of fear.”
So what? “This mood reflects the character’s inner turmoil and foreshadows later events.”
So what? “It prepares the reader for the story’s climax and emphasizes the theme of loss.”
3. Commentary Expansion with Sentence Starters
Provide sentence starters to help students begin their commentary and expand it naturally. Examples include:
“This suggests that…”
“By doing this, the author shows…”
“This reveals…”
“As a result, the reader understands…”
“This connects to the theme of…”
Students can write one sentence using a starter, then add 1-2 more sentences explaining further.
4. Evidence-Commentary Matching
Give students a list of evidence statements and a separate list of commentary sentences. Their task is to match each piece of evidence with the best commentary and then expand that commentary with additional explanation.
This exercise helps students see how commentary relates directly to evidence and how to build on it.
Teaching Explanation Layering in Practice
Layering explanation means building commentary in steps, each adding more detail or insight. Here’s how to guide students through it:
Start with a basic observation: What does the evidence show?
Add interpretation: What does this mean in the context of the essay?
Connect to bigger ideas: How does this relate to the theme, character, or argument?
Consider implications: Why should the reader care? What does it reveal about the text or topic?
Encourage students to write commentary in multiple sentences, each addressing one of these layers. This approach prevents commentary from being a single, shallow sentence.
Sample Paragraph with Balanced Evidence and Commentary
Here is an example paragraph showing balanced evidence and layered commentary:
In To Kill a Mockingbird, Atticus Finch’s calm demeanor during the trial demonstrates his moral strength. When he says, “But there is one way in this country in which all men are created equal,” he appeals to the jury’s sense of justice. This statement suggests that Atticus believes deeply in fairness, even when society resists it. By calmly presenting his argument, Atticus contrasts with the hostile courtroom atmosphere, highlighting his role as a voice of reason. This contrast emphasizes the novel’s theme of standing up for what is right despite social pressure.
Notice how the paragraph includes a quote, explains its meaning, connects it to character traits, and links to the broader theme.
Tips for Teachers to Support Commentary Growth
Model strong commentary: Show examples of weak vs. strong commentary.
Use peer review: Have students give feedback on each other’s commentary depth.
Encourage revision: Commentary often improves with rewriting.
Focus on clarity: Commentary should be clear and specific, not vague.
Ask guiding questions: Help students think about why evidence matters and what it reveals.
Celebrate insight: Praise students when they make thoughtful connections or interpretations.
Final Thoughts on Building Commentary Skills
Teaching commentary depth is essential for helping students write essays that stand out. Balanced evidence and expanded explanation create persuasive, insightful writing. Using exercises like the “Why It Matters” drill and layering “So What?” questions gives students tools to develop their ideas fully.
Encourage students to practice these techniques regularly. Over time, they will learn to write commentary that not only supports their claims but also engages readers with clear, meaningful analysis. This skill will serve them well beyond high school, in college writing and any situation where strong communication matters.
