Stimulus Activities

A Stimulus Activity allows the instructor to provide a stimulus/prompt video or PDF that student presenters can then respond to, with video and written feedback. This is particularly useful in interpreting or interviewing activities, or for reinforcing skills that you might be working on in class.  If you would like to see how students respond to these activity types please see Posting to a Stimulus Activity.

System requirements for Stimulus Activities


Stimulus Activities require your browser to process two video streams simultaneously:  playback of the stimulus video and the recorded submission. While this is easily accomplished by current generation computers, older ones may struggle to smoothly render both the stimulus and the recording at the same time. The primary constraints are video processing power, system memory, and CPU horsepower in addition to internet connection speed. In general, having a dedicated video card and relatively recent processor will provide the best results.

If your computer is struggling to keep up with both videos simultaneously, some options are:

  • Restart the computer to free up the highest amount of resources possible.
  • Close all other applications and tabs.
  • Arrange to use a newer machine for your Stimulus activities in GoReact.

Note for Chromebook users

Due to the widely varying hardware and (often limited) system resources in Chromebooks, their performance with GoReact may or may not be acceptable. In our testing, newer, more robust Chromebooks generally work fine, while older or more limited Chromebooks will struggle or can fail outright. If your GoReact experience on a Chromebook isn't satisfactory, you'll most likely need to use a different device.

Please note that stimulus activities are not currently supported on mobile devices.

How to set up a Stimulus Activity


Create a New Activity and select the Stimulus Activity type. On the Activity Settings screen that follows, you'll see "Stimulus/Prompt Media" in a red section of the panel. Click the "+Add Media" button to add the stimulus by your preferred method.

With the Stimulus activity type, you can also have your students provide their own stimulus.  To do so, select "Student Selected Stimulus/Prompt."

How to critique a Stimulus Activity


Giving feedback on a student's Stimulus submission is just like giving feedback on any other video session. To start, click the thumbnail of the video on your Dashboard to begin playback.  Then enter your critique in the feedback panel on the right.

You'll see the Stimulus Media shown to the left of the student's recording. These two videos can be resized by dragging the bar between the videos or the bar between the video and feedback panels. As you play the session, the Stimulus Media will play and pause when it was played or paused during the student's recording.

Why do I hear an echo or double audio?  If the student recorded without headphones you will likely hear the stimulus coming from both videos.  You can click the "Mute" button in the lower left corner of either video to silence one of them and get rid of the echo.
