GCF Learn Free - Excellent Tutorials for Computer Science Basics

 

GCF Learn Free is a website and YouTube channel that I discovered this week when looking for some new tutorial videos to post in Google Classroom for my PC repair class and for my Intro to Computer Science class. Based on the number of subscribers GCF Learn Free has, I appear to be late to the party in "discovering" this great resource. 

On GCF Learn Free you'll find dozens of tutorials on basic topics related to computer science. This week I shared the Inside a Computer video with my PC repair students. Today, I shared GCF Learn Free's video about algorithms with my Intro to Computer Science students.  What I liked about the videos is the brevity and clarity. Both videos gave students just enough information to remind them of the lessons that I taught in class. 

 

How to Make a Similar Video

Both of the videos featured above are made using clip art and simple animations that you can find in Google Slides, PowerPoint, and Keynote. Record those slides with a screencasting tool and you have a simple animated video. In this video I demonstrate that process. 

How to Protect Privacy When Publishing Recordings of Virtual Meetings

During yesterday's episode of Two Ed Tech Guys Take Questions & Share Cool Stuff someone asked for a suggestion on how to blur or mask students' faces when publishing the recording of a Zoom class meeting. My suggestion was to upload the recording to YouTube and then use the automatic blurring tool built into YouTube's video editor. The automatic blurring tool will automatically detect faces in the video and blur them out for the entirety of the video. Alternatively, you can use the blurring tool to selectively blur faces and or objects in your video. 

Here's my video on how to use the automatic blurring function in YouTube. 

 
Alternative Solutions: 
If you don't want to or can't use YouTube, you could import your Zoom recording into a video editor like WeVideo or iMovie and then selectively blur or hide faces. Doing it that way would take a lot more time than using the automatic blurring tool in YouTube.
