How it Works

Traffic Lite is a simple Chrome extension that lets teachers send pop-ups to students, on which they can quickly share their understanding using a green, yellow, or red signal. Teachers instantly see those responses in a live dashboard, making it easy to spot who needs help and when.

Follow the steps below to use Traffic Lite with your students:

1. Setup

  1. Click Here to Install the Traffic Lite Chrome Extension.

  2. After installation is complete, click the extension icon on your Chrome toolbar to sign in.

  3. Click the extension icon again to open Traffic Lite.

Note: To avoid having to share the installation link with students, the extension can also be installed via the Google Admin Console by a school or district technology lead.

2. Start a Session

  1. On the teacher dashboard, use the drop-down menu to select a Google Classroom you’d like to use Traffic Lite with (this will typically be the Google Classroom for your current, live class)

  2. Use the “Post a Question” drop-down (or write a custom prompt) to send to students if you’d like. Use the “Preview Student Popup” link to see what students will see.

  3. Click “Start Session.” Students will automatically receive a pop-up window on their devices within 20-30 seconds, which they can use to respond to your prompt by clicking a color (red, yellow, or green) and clicking “send.”

Note: Student pop-ups will continue to reappear every 20-30 seconds on students’ screens until they select a color and click “send.” Students can also open the pop-up themselves by clicking the extension icon on their Chrome toolbar.

3. Sort, Filter, & Export

  1. Student response data can be sorted and filtered by clicking the pie chart and/or by using the arrows in the headers of the data table.

  2. Once a session is stopped, teachers can then export the data as a CSV file.

Note: Once a session is stopped, student pop-ups will show ‘Not Active’ and will no longer be clickable.
