CodeHS has several features that can help ELLs succeed in their computer science courses. This article will describe these features as well as provide some additional strategies for ELLs. See Intro to Karel Programming with Karel the Dog (Español) or Intro to Python with Tracy (Español) to learn more about our Spanish course options.

Block Coding

You can enable block coding (rather than typing code) on a per-student basis or for an entire section to assist students whose language or typing skills are inhibiting their progress. For more about Block Settings, check out this article: Block Settings.

The following languages are compatible with Blocks:

  • Karel in JavaScript

  • HTML

  • Coding in Art, Music, or Sports

The following courses include some Block Compatible Activities:

  • Intro to Computer Science in JavaScript

  • AP Computer Science Principles in JavaScript

  • Computing Ideas

  • Web Design (Note: Block Coding not available in CSS)

  • Intro to Programming with Karel

Enabling Block Coding from Your Roster Page

  1. Click the gear icon next to the student's name

  2. Toggle the Blocks setting for modules, lessons, or even specific assignments:

Please Note: Some schools may block access to YouTube and videos may only be available to view on CodeHS.

Use Slides to Review Concepts

While instructional videos are ideal for some, other students may benefit from viewing the Slides, especially if they struggle with the speaking pace. Students can take notes and work at their own pace (rather than the pace of the video speaker).

Students can access the Slides for any video by selecting Slides at the top:

CodeHS Glossary

At, you can find a full list of terms and definitions used in the CodeHS curriculum. You can filter by language (JavaScript, Python, HTML, etc). using the search bar. Click on any term to show an example:

Printable Handouts, Quizzes, and Slides

Many lesson plans include additional worksheets, handouts, and physical activities to help make some of the more abstract concepts of programming more accessible. These activities can help students think about solving problems in a variety of ways.

With CodeHS Pro, teachers have the ability to print slides, quizzes, handouts, and other resources, which can be an excellent adaptation for ELLs. To print a resource:

  1. Click into a section

  2. Click the blue Resources button

  3. Navigate to a lesson plan and click the Lesson Plan button to load all resources

  4. Find and print any slides, quiz, or handouts:

Additional Strategies

Personal Dictionary and Flash Cards

Using the CodeHS Glossary, Students can make flash cards or create a personal dictionary to help reinforce programming concepts. Encourage students to draw pictures, use different colored pens, and/or paraphrase definitions using their own words. For ELLs, it may be helpful to make additional flashcards highlighting capitalization, syntax, and common commands. Students can also use the Docs tab as a guide to create these study tools.

Word Wall

A vocabulary word wall in the classroom can include vocabulary from each lesson or module. The word wall can be printed and hung on a wall of the classroom to serve as yet another interactive and visual tool for students.
