Research for Teachers

One of the things I genuinely love about teaching high school students is the level of thinking that can emerge in classroom discussions.

By the time students reach high school, many have spent years developing analytical and interpretive skills through the work of talented middle school teachers. As high school teachers, we often get to explore difficult themes, nuanced authorial choices, ethical tensions, symbolism, and complex concepts together. Those conversations can be intellectually challenging, engaging, and genuinely enjoyable.

But early in my teaching career, I began noticing something that surprised me.

Some students who could discuss literature brilliantly struggled to communicate those same ideas clearly in writing.

In discussions, they could explain sophisticated interpretations, respond thoughtfully to others, and make insightful connections between texts and concepts. Yet when they attempted to translate those same ideas into essays, the writing often became fragmented, unclear, or simplistic.

At first, I found this confusing.

How could students think so deeply yet struggle to communicate those thoughts effectively on paper?

Over time, I realized that the issue was not necessarily a lack of understanding. Often, students had the ideas. What they lacked were the sentence-level writing skills necessary to express those ideas clearly and precisely.

That realization fundamentally changed the way I approached writing instruction.

Like many teachers, I had initially assumed that sentence-level work was something students should already know by high school. Once students reached secondary English, I believed our focus should primarily be on higher-order thinking: thematic analysis, argumentation, literary interpretation, and sophisticated textual analysis.

And those things absolutely matter.

But I gradually learned that students cannot consistently produce sophisticated analytical writing if constructing clear, controlled sentences still requires enormous cognitive effort.

Reading The Writing Revolution 2.0 later helped articulate many of the observations I had been making in my classroom. Hochman and colleagues argue:

“If students haven’t learned how to write an effective sentence, that is where instruction needs to begin—no matter what the student’s age or grade level” (Hochman et al., 2024).

That idea resonated with me immediately because I had seen firsthand how older students often benefited enormously from revisiting foundational writing skills.

Importantly, going “back to basics” did not mean lowering expectations.

It meant strengthening the foundation that allowed students to express increasingly sophisticated thinking.

Once students revisited the structure of a clear sentence, understood how syntax could be manipulated to create emphasis and effect, and developed the vocabulary necessary to communicate precise meaning, something interesting began to happen.

Their writing started catching up to the sophistication already present in their thinking.

Students who previously wrote vague or repetitive analytical responses began crafting more deliberate and controlled arguments. Some learned how sentence variety could create rhythm and emphasis. Others became more intentional with transitions, clause structures, and vocabulary choices. Their essays became clearer not because their ideas had suddenly improved, but because they finally had stronger linguistic tools to communicate those ideas effectively.

What I found especially important was recognizing how cognitively demanding sentence construction actually is.

Hochman and colleagues explain that sentence-level writing should not be dismissed as “too basic” for older students because sentences are “literally miniature compositions” (Hochman et al., 2024). Even composing a single sentence can require students to manage grammar, syntax, punctuation, vocabulary, organization, and meaning simultaneously.

When students are still struggling to coordinate those skills automatically, much of their cognitive energy becomes consumed simply trying to produce a coherent sentence. That leaves considerably less mental capacity available for the more sophisticated thinking required in analytical writing.

In other words, students may fully understand a text intellectually while still lacking the fluency needed to communicate that understanding effectively in writing.

This became especially visible during literary analysis.

A student might verbally explain a nuanced interpretation of a character’s motivation, but when writing independently, produce something far less sophisticated:

“Macbeth changes because he wants power.”

The thinking behind the statement was often more sophisticated than the sentence itself revealed. What students frequently needed was explicit instruction in how to expand, qualify, and refine their ideas through sentence construction:

“Macbeth’s growing obsession with power gradually erodes his moral judgment, leading him to justify increasingly violent actions in pursuit of authority.”

The second sentence does not necessarily reflect a deeper idea. Rather, it reflects greater control over syntax, vocabulary, and precision.

That distinction matters.

Too often, weak writing is interpreted as weak thinking. Sometimes that is true. But sometimes students are cognitively capable of sophisticated analysis while still lacking the writing fluency necessary to communicate it clearly.

This is one reason I have increasingly come to believe that explicit writing instruction remains essential even at the high school level.

Sentence-level instruction is not remedial. It is foundational.

In fact, some of the most effective writing growth I have witnessed with older students has come not from assigning increasingly long essays, but from deliberately slowing down and focusing on smaller units of writing first. Sentence combining, sentence expansion, syntax manipulation, and vocabulary precision often produce far greater improvement than repeatedly assigning full essays without sufficient scaffolding.

Importantly, students themselves often find this empowering.

Many students who previously viewed themselves as “bad writers” began gaining confidence once the invisible mechanics of writing were made more explicit. Writing stopped feeling mysterious. Instead, it became a series of manageable decisions and strategies that could be practiced and improved over time.

Looking back, one of the most valuable lessons I learned early in my teaching career was that revisiting foundational skills is not a sign that students are incapable of higher-level thinking.

Sometimes it is precisely what allows higher-level thinking to emerge more clearly.

High school students are absolutely capable of sophisticated analysis, insight, and interpretation. But helping them communicate those ideas effectively sometimes requires us to step back from the essay itself and return to the sentence.

And honestly, that is not “basic” work at all.
