Chat tools and polling services provide good ways to hear from all of the students in a classroom. These kinds of tools, often referred to as backchannel tools, allow shy students to ask questions and share comments. For your more outspoken students who want to comment on everything, a feedback mechanism provides a good outlet for them too. Over the years I’ve used a variety of feedback tools in my classroom. This is my updated list of backchannel and informal assessment tools for gathering real-time feedback from students.

Classroomscreen is a service that lets you create a homescreen on which you can place reusable countdown timers, stopwatches, polls, noise meters, random name selectors, and more helpful classroom management tools. With the polling tool in Classroomscreen you can display a question for your students and have them respond with a multiple choice selection or by choosing a smiley face. See my screenshot below for more details. 

Yo Teach! lets you create online backchannel spaces to facilitate discussions. To get started on Yo Teach! simply go to the site and name your room. You can get started by just doing those two steps, but I would recommend taking a another minute to scroll down the Yo Teach! site to activate the admin function, the password function, and to select “avoid search.”  The “avoid search” option will hide your room from search results so that people cannot find it without being given its direct URL. The password function lets you set a password that must be entered before students can participate in the chat. The admin features of Yo Teach! let you mute or remove students from a discussion, delete your room, and view statistic about the usage of your room. The admin function that reveals statistics will show the names of participants and how active they have been in your Yo Teach! room. Here’s a video overview of Yo Teach!

ClassPoint. It’s a great little tool that you can use to build interactive quizzes and polls into your PowerPoint presentations. You can also use it to annotate slides, create whiteboards on the fly, and share your annotations with students. In this short video I provide a demonstration of how ClassPoint works. The video shows a teacher’s perspective and a student’s perspective of how ClassPoint can be used in your classroom. 

Ziplet is a service for gathering feedback from your students in a variety of ways. The simplest way is to create an exit ticket by using one of the dozens of pre-written questions provided by Ziplet. Ziplet does not require students to have accounts to respond to exit ticket questions. Students can simply enter an exit ticket code that you give to them before they answer the question. What Ziplet offers that is somewhat unique is the option to respond directly to individual students even when they are responding to a group survey. The purpose of that feature is to make it easy to ask follow-up questions or to give encouragement to students based on their responses to a question posed to the whole group. Here’s a short video about how to use Ziplet.

Plickers is a great student response system for classrooms that aren’t 1:1 or for anyone who would rather not have to go through the trouble of trying to get all students onto the same webpage or chatroom at the beginning of a lesson. Plickers uses a teacher’s iPad or Android tablet in conjunction with a series of QR codes to create a student response system. Students are given a set of QR codes on large index cards. The codes are assigned to students. Each code card can be turned in four orientations. Each orientation provides a different answer. When the teacher is ready to collect data, he or she uses the Plickers mobile app to scan the cards to see a bar graph of responses. Click here for three ideas for using Plickers in your classroom.

Mentimeter is an audience response tool lets you create polls and quizzes for your audience to respond to during your presentations. Responses to open-ended poll questions can be displayed as a word cloud, but there isn’t a true chat function in Mentimeter. You can create and display polls and quizzes from the Mentimeter website or you can use their PowerPoint Add-in to display your polls and quizzes from your slideshow. Your audience members can respond from their phones, tablets, or laptops.

The Q&A function built into the presentation mode of Google Slides is a good option for gathering questions from students when they are viewing slides that you or their classmates present. Likewise, posting a simple question in Google Classroom is a good way to quickly get a sense of what your students know about a topic before you begin a lesson or what they think was important in a lesson that you just taught. 
Poll Everywhere is a service that allows you to collect responses from an audience via text messaging. The free plan for K-12 educators provides selection of features and quantity of responses that is adequate for almost any classroom. One of the neat ways to display feedback gathered through Poll Everywhere is in word clouds. 
I’ve been using Padlet since it was called WallWisher back in 2009. Padlet enables me to have students not only share exit responses as text, but to also share exit responses as hyperlinks. For example, if my students have been working on research projects I will ask them to share a link to something they found that day along with an explanation of how it is relevant to their research.
Formative provides you with a place to create online assignments that your students can respond to in class or out of class. Assignments can be as simple as one question exit tickets like “what did you learn today?” to complex quizzes that use a combination of multiple choice, short answer, and true/false questions. You can assign point values to questions or leave them as ungraded questions. The best feature of Formative is the option to create “show your work” questions. “Show your work” questions enables students to draw responses and or upload pictures as responses to your questions. When you use this question type students will see a blank canvas directly below the question. On that canvas they can draw and or type responses.
