My Take
Pear Deck is incredibly user-friendly and offers many free tools. It is easy to embed questions into a slide, and joining the class group is very easy for students. They create a summary of performance at the end of a session as well, which helps review students' progress. For people comfortable with Google Slides, this program is very easy to use to elevate your slidedecks.
How I Use It
I have used Pear Deck in various educational settings as both the student and educator. Embedding questions throughout slides helps to check for knowledge and gain participation and feedback from all students, rather than just the ones that voice their opinions.
