Classroom Response System (CRS): Classroom Response System (CRS) Robert T. Thomas – ECI 511 What Is a CRS? : What Is a CRS? A classroom response system is a set of hardware and software that facilitates teaching activities such as the following. A teacher poses a multiple-choice question or true false question to his or her students via an smart board, overhead, or computer projector, using some type of presentation software. What Is a CRS?: What Is a CRS? Each student submits his or her answer to the question using a handheld transmitter (often called a “clicker”) that beams an infrared or radio-frequency signal to a receiver attached to the teacher’s computer. What is a CRS: What is a CRS Software on the teacher’s computer collects the students’ answers and instantly produces a histogram showing how many students chose each answer. What Is a CRS?: What Is a CRS? To see a brief video of a CRS in action, visit the link below: The video is narrated by Dee Silverthorn of the School of Biological Sciences at the University of Texas at Austin. Teaching with a CRS : Teaching with a CRS Activities Ask the Audience : Most people are familiar with the TV show "Who Wants to Be a Millionaire“. The “Ask the Audience” lifeline is an example of the most basic CRS activity which allows the instructor to pose a multiple-choice question and displays the results in real-time. Questions and lecture time can be intermixed to allow instructors to gauge student understanding and adjust lectures accordingly. Peer Instruction : The teacher asks a question to the class. The students transmit their individual answers using the clickers. The teacher checks the histogram of student responses. If significant numbers of students choose the wrong answer, the teacher instructs the class to discuss the question with their neighbors. After discussing the question for a few minutes among themselves, the students resubmit their answer. This technique often (but not always!) results in more students choosing the correct answer as a result of the peer instruction phase of the activity. Attendance and Quizzes : If each student is assigned a specific clickers for the duration of the course, then a CRS can be used to take attendance or to give for-credit multiple-choice and true-false quizzes and tests. Interactive Demonstrations : In science classes, students can be asked to predict the outcome of an experiment prior to being shown the experiment. This gives the teacher a sense of the students' preconceptions and increases the surprise value of the experiment when students see just how many of their classmates expected different outcomes. Data Gathering : A CRS can be used to quickly gather demographic, opinion, or other data from a class full of students. This is often useful in social science classes that utilize social or economic experiments in the classroom.

CRS systems overall are very reliable, but as with any technology system, problems can arise and teachers should always have alternate material available. Writing effective questions can be very challenging. The system is only as effective as the questions asked. Using the system does take time especially if students are not assigned clickers for the whole term. It also takes time for students to read and answer questions. Teachers may misunderstand why students give the wrong answer. If a significant number of students answer a question wrong, then the teacher may need to re-teach the material in a different manner. This may even require that the lesson plan be revised on-the-fly. Types of Questions: Types of Questions CRSs enable a teacher to ask several different types of questions.

Each manufacturer has own software package available. Best Practices: Best Practices According to TurningPoint Use an "Ice Breaker" to introduce use of TurningPoint's response system. Include an "Answer Now" prompt to differentiate between lecture slides and interactive polling slides. Use a "Correct Answer" indicator to visual identify the appropriate answer. Increase responsiveness by using a "Countdown Timer" which will close polling after a set amount of time. Not all questions have to have a right answer. Use TurningPoint to reveal opinions and insights. Assign point values to questions instead of simply setting them as right or wrong. Use point values to award attendance and/or participation points. Use low-stakes quizzing composed of 10 items to make sure that students have done their reading before they come to class. Include short bursts of 3-4 questions mixed in with other more traditional presentations and activities to keep your students and participants engaged. Respond to meeting or classroom discussions-Insert questions on-the-fly by pressing F5 on your keyboard or selecting the arrow next to the on-the-fly icon in the TurningPoint ShowBar. TurningPoint is SMART Aware. This means that if you have a SMART Board interactive whiteboard in your classroom, you can just pick up your pens and start annotating over your slides. For more information refer to your SMART Board user guides. Change of TurningPoint's default settings to match your presentation color scheme. Click on the Spectacles icon on the TurningPoint toolbar. Add a fun, competitive element-track individual teams, groups, or students using a "Participant List". Add a "Fastest Responder" slide or view group results. To find out who has yet to respond to a question, press F7 or F8 which will show a "Response Grid" on screen with ResponseCard keypad numbers and names. Track changes in understanding or opinions by asking the same question at the beginning and end or your presentation. See side-by-side results using a "Comparison Slide."
