Poll Everywhere
Principal function(s): Poll and survey creatorsVocabularyGrammarTeacherYou Supply
Poll Everywhere is a tool that allows presenters to create interactive polls, quizzes, and surveys for live audiences. Participants can respond to questions using their mobile devices or computers, while results are displayed in real time, and can later be downloaded. Poll Everywhere offers a limited free account where users may record up to 25 responses per poll, without including its grading functionality. It requires having an account for poll creators. Poll Everywhere was developed by Jeff Vyduna, Brad Gessler, and Sean Eby.
Evaluation: Poll Everywhere is a valuable tool for getting immediate feedback in the classroom, conducting quizzes, and more. It is useful for making in-person teaching more engaging. Poll Everywhere includes many functionalities, but a substantial downside is that its free version is quite limited.
Cost: Free with registration + paid plans available.
