Classroom Response Systems (“Clickers”)
What is it?
Clickers are a great new technology used in “lecture based” classrooms used to assess student learning almost instantly. Each student registers their clicker to the class, for example, biology, and the teacher asks questions that each student is able to answer using their clickers. The teacher and the whole class can then see their results instantly. The results of the questions are shown using a histogram and the students can see how many answered the question right/wrong. It is a great tool to get the whole class involved, see if the students are understanding the material as the teacher is going over it through assessment, and it can also be used to take attendance of the students using the clickers.
Clickers can be a great tool to use in biology when teaching complex ideas and then applying the knowledge taught to critical thinking questions. The teacher can then take the class to the next level by instant polling and surveying through anonymous student feedback (students can answer with out being afraid of being wrong) and can be used in small to large size classrooms in every subject!
How it works.
- A teacher poses a multiple-choice question to his or her students via an overhead or computer projector.
- Each student submits an answer to the question using a handheld transmitter (a “clicker”) that beams a radio-frequency signal to a receiver attached to the teacher’s computer.
- Software on the teacher’s computer collects the students’ answers and produces a bar chart showing how many students chose each of the answer choices.
The teacher makes “on the fly” instructional choices in response to the bar chart by, for example, leading students in a discussion of the merits of each answer choice or asking students to discuss the question in small groups
What the results show.
The results of the clickers shows a histogram of the percentages of students who answered the question right and how many answered wrong. It also shows the how many students answered A, B, C, D and so forth.

Why use clickers in the classroom?
- To promote student learning
- To assess student learning and go over material again if need be
- To formally assess each students learning
- To take attendance
- To bring excitement and a fun challenge into the classroom
