Sentence Stems For Writing

Getting Started With Sentence Stems

Sentence stems are the opening fragments you give students—or yourself—to launch a sentence. Something like "According to the data," or "Despite the initial results." You leave the rest blank and fill it in. That is basically all there is to it. They are useful when someone does not know how to start. They are less useful when someone over-relies on them. I spent a long time watching people use these the wrong way. The most common mistake is handing out a master list of fifty stems and telling students to memorize them. That does not work. Memorization without context produces stiff, robotic writing. Instead, pick three stems that match the task at hand and drill those until they become automatic. The repetition matters more than the quantity of stems.

Sentence Stems For Writing

Here is the practical breakdown. Stems generally fall into functional categories, and you should organize yours this way. Cause and effect stems include phrases like "This change resulted in" or "The primary reason for was." Comparison stems include "In contrast to," or "Similarly,". Opinion and evidence stems look like "I believe that because" or "The evidence suggests." Each category serves a different rhetorical purpose. If a student is writing an argumentative paragraph, they need a different set than if they are writing a lab report. Do not mix them carelessly. The real value comes from drilling stems in context. I have a worksheet routine that takes about twenty minutes. I write a short paragraph on the board with the stems removed. Students read it, identify what stem belongs in each gap, then rewrite the paragraph using the stems from memory. This forces retrieval practice, which is different from recognition practice. Recognition is passive. Retrieval is where the actual learning happens. I do this exercise twice a week for a semester and the improvement in student writing is noticeable. Not dramatic. Noticeable. One thing people rarely mention: sentence stems can create a false sense of fluency. A student can produce a perfectly structured sentence using "Furthermore, one might argue that..." and have absolutely nothing original to say. The sentence looks academic but it is empty. I caught this in my own grading about five years ago and it changed how I teach. Now I require students to underline the part of the sentence that contains their own idea. If the underline is shorter than the stem itself, the sentence is not doing enough work. It is just decoration.

Here is the workaround I use when that happens. I take a stem-only sentence and ask the student to replace the first half with something from their own thinking. Keep the stem. Replace the content. Then swap the stem and keep the content. This builds flexibility. Rote reproduction alone does not transfer to independent writing.

Building Your Own Stem Bank

Collect stems from texts your students are actually reading. Textbook passages, journal articles, even well-written newspaper editorials. Pull out the transitional phrases and the claim-making openings. Write them on index cards or in a shared document. Organize them by function. The organization is important because students who can locate the right stem quickly will use them more effectively than students who are flipping through a disorganized list. Avoid stems that are too long. "It has been argued by many scholars throughout history that..." is not a stem. It is a crutch. Long stems encourage padding. Short, functional stems like "Scholars argue that" or "Historically," are far more usable. Students should be able to insert them mid-paragraph without breaking the flow. There is a hard limit to how far stems can take a writer. Advanced writers eventually need to internalize these structures so thoroughly that the stems disappear. The writing should not signal its scaffolding. If a reader can point to a stem and say "they used a template," the exercise has failed. The goal is invisible structure, not visible structure.

I stopped assigning stem lists to upper-level students two years ago. They were producing competent but formulaic paragraphs. I switched to having them analyze published essays and extract the transitional language themselves. The students who did this produced noticeably more natural writing in the following units. It takes more class time upfront. About thirty minutes instead of ten. The payoff is worth it.
