If you have used edtech tools like Socrative, Kahoot, MoveNote, and even the now-defunct InfuseLearning, you must take a look at PearDeck. This interactive website and Google Drive app adds interactivity to any slideshow by integrating free-text responses, multiple choice answers, freehand drawing renditions, drag-and-drop indicators, overlapping visuals, and even embeddable YouTube videos. Mixed in with other fruitful classroom activities during the school year, PearDeck will definitely help produce student engagement and, ultimately, acquired knowledge.
No need to worry about investigating PearDeck yourself. Just take a look at these two video tutorials, and your classes will be ripe for a rocking learning activity.
