Helping Students Access the Learning: Differentiating Content in Computer Science

In the first post, we looked at why differentiation matters in computer science. Students come into our classrooms with different backgrounds, confidence levels, reading skills, problem-solving habits, and experiences with technology.

The goal is not to lower the bar. The goal is to help more students reach it.

One place to start is with content.

Content is what students use to access the learning. In a computer science classroom, that might include notes, directions, code examples, vocabulary, diagrams, flowcharts, videos, or reference sheets.

Differentiating content does not mean changing what students are expected to learn. It means changing how students access the information they need in order to learn it.

In CS, students are often juggling several things at once. They may be learning new vocabulary, reading directions, understanding syntax, using a new tool, solving a problem, and debugging errors all in the same lesson. For students who are new to computer science, that can be a lot to manage.

Content supports help reduce some of that overload.

They give students a clearer path into the learning before they are asked to practice or produce something on their own.

Using AI to Create Student Notes

One way to differentiate content is to give students better access to the important information before they are asked to use it.

AI can be useful here because it can help turn lesson materials into student-friendly notes. A teacher could use the lesson plan, objectives, learning targets, state standards, vocabulary, and activity directions as the starting point. From there, AI can help organize the most important information into a focused resource students can actually use.

The key is giving AI clear parameters. For example, the teacher might ask for notes written for 9th grade students, limited to one page, formatted for Google Docs, and focused only on the information connected to the lesson objectives and learning target. This keeps the notes from becoming too long or too broad.

The teacher still needs to review the notes before giving them to students. AI can help organize the content and simplify the language, but the teacher needs to make sure the information is accurate, clear, and aligned to what students are expected to learn.

Chunking Directions

Another simple way to differentiate content is to chunk directions.

Programming tasks often include a lot of information at once. Students may need to know what file to open, what function to write, what condition to check, what method to use, how to test the program, and how to submit their work.

When all of that is written in one large block, students can lose track of what they are supposed to do first.

Chunking directions makes the task easier to read, follow, and revisit. It does not change the assignment. It simply makes the information easier for students to process.

For many students, that small change can make a big difference.

Flowcharts and Visual Supports

Flowcharts can be especially helpful in programming because they let students see the logic of an algorithm before they worry about syntax.

This matters because students often get stuck on the code before they fully understand the thinking behind the code. They may worry about punctuation, indentation, method names, parentheses, or exact syntax before they understand the sequence of steps.

A flowchart gives students another way into the problem.

For example, a student might be asked to write a function that uses a loop to paint a row. Before students write the code, they could use a plain-English flowchart to understand what the function should do.

Flowchart illustrating the function "paint_row", showing a loop that checks if the painter can move forward, paints each square blue until the end, and finally paints the last square.

The flowchart shows the structure of the loop:

• Start the function.

• Check if the Painter can move forward.

• If yes, paint the current square and move forward.

• Then check the condition again.

• If no, paint the final square and end.

This helps students see that the loop is not just “doing something over and over.” The loop continues while a condition is true. When that condition is no longer true, the program moves on.

One practical teacher move is to start with the answer key or a sample solution. A teacher can paste the solution into AI and ask it to turn the code into a plain-English flowchart. The teacher would still need to review the flowchart for accuracy, but this can be a quick way to create a visual support from a programming task that already exists.

This works well because the flowchart gives students access to the thinking behind the code. They can understand the algorithm first, then use that understanding to write, explain, debug, or modify the program.

Reference Sheets

Reference sheets are another practical way to differentiate content.

In programming, students are often expected to remember a lot at once. They need to understand the concept, follow the directions, choose the right command, use the correct syntax, and test their work. When students forget one method or one piece of syntax, they can get stuck even if they understand the larger idea.

A reference sheet gives students quick access to the information they need so they can keep working.

For example, if students are working with a Painter object, a reference sheet might separate information into attributes and methods.

Attributes describe information about the object. Methods describe what the object can do.

Documentation for Painter object in Code.org

A chart like this helps students quickly see the difference between what the object knows and what the object can do.

For example, the Painter’s direction tells us which way it is facing. The move() method tells the Painter to move forward. The canMove() method checks whether the Painter can move forward.

The point of a reference sheet is not to give students the answer. It is to reduce the number of small details they have to hold in memory while they are trying to solve the bigger problem.

A good reference sheet still requires students to think. They still have to decide which method makes sense, when to use it, and how it fits into the algorithm. The reference sheet simply gives them access to the language and tools they need to keep going.

Preview Videos

Preview videos can also support content access.

A short video before or during a lesson can help students hear the explanation more than once. This is useful for students who need extra processing time or who benefit from seeing an example before trying something independently.

Videos also give students control. They can pause, rewind, slow down, use captions, or rewatch a section. That kind of access can be helpful when students are learning a new programming concept or using a new tool.

The video does not replace instruction. It gives students another way to access the content.

Reading-Level Supports

Sometimes the barrier is not the computer science concept. Sometimes the barrier is the way the directions or explanation is written.

Students may struggle because the text is too long, too technical, or too dense. In that case, content differentiation might mean adjusting the reading level while keeping the same learning target.

That could include shortening paragraphs, defining key vocabulary, using bullets, adding examples, or removing unnecessary wording.

The goal is not to remove the challenge from the CS concept. The goal is to remove unnecessary barriers that prevent students from accessing the concept in the first place.

Keep the Target the Same

Content differentiation works best when the learning target stays clear.

Students may access the content in different ways. One student may use notes. Another may use a flowchart. Another may use a reference sheet. Another may watch a short preview video.

But the goal remains the same.

They are still working toward the same learning target. The teacher is simply providing different ways for students to access the information they need to get there.

That is what makes content differentiation manageable. It does not require a completely different lesson for every student. It requires thoughtful supports that help more students enter the learning.

In computer science, that might be the difference between a student shutting down and a student having enough support to keep going.
