Information is power! What was once limited to paper has gone digital. Now teachers can send announcements, survey their classes, offer exit tickets, track behavior, and assess students with a variety of innovative and free online tools. These websites and apps can provide immediate feedback and are handy for formative and summative assessments.
Use the Post-it Plus app to capture, organize, and share what's written and/or drawn on sticky notes. Currently the app is only available for iPhone and iPad.
Use the Remind website or app to send text messages and emails to groups of students or parents. Teachers never see students' phone numbers, and students never see theirs.
Create multiple choice and open-ended polls with Poll Everywhere. Students respond by going to a URL on any device or computer or by sending a text message. See the results in real-time.
Nearpod allows teachers to send content to students' computers, iPads, and tablets. The teacher can upload a presentation and then add interactive elements like polls, quizzes, and drawing tools before pushing it out to students' screens.
Socrative is another student response tool. The teacher has an account (and you can login using Google). Questions can be student paced with or without immediate feedback, or they can be teacher paced.
Use Padlet to collect text, weblink, images, and videos from students. The teacher creates an account, but students can simply access a teacher's Padlet wall by going to its web address. Teachers can create many different walls. Recommended settings for your wall include using the Moderate Posts feature under the Privacy settings. It might be helpful to change the layout to Grid or Stream.
Richard Byrne at Free Technology for Teachers has complied a chart that compares nine different students response tools. You can see which ones allow anonymous replies, teacher moderation, support images, and require registration.
Quizizz is a lot like Kahoot. The teacher can make a quiz or copy a public quiz. Students enter a code to join the quiz. Quizizz's advantage over Kahoot is that the question and responses appear on each students' screen, not just the teacher's.
SketchParty TV is a Pictionary game that you play in two teams. The apps is for iPhone or iPad and requires an Apple TV, VGA or HDMI adapter, or AirPlay software like AirServer or Reflector. You can use their word lists or input your own words.
