Cold calling is a teaching technique used by instructors to randomly select students to answer questions, contribute to discussions, or present solutions. The approach is widely used in classrooms to engage students, promote active participation, and stimulate critical thinking. However, cold calling can be daunting and uncomfortable for both students and teachers, especially when not executed properly. This article provides insights into the dos and don’ts of cold calling in the classroom, with tips for effective implementation.

The Benefits of Cold Calling

Cold calling has numerous benefits, both for students and teachers. Firstly, the technique ensures that all students actively participate in classroom discussions and activities, promoting an inclusive learning environment. Secondly, it helps to enhance critical thinking, as students are required to think on their feet, analyze the question, and provide a response. Thirdly, it helps to develop confidence in students, especially those who may be shy or introverted, as it provides them with a platform to contribute to class discussions. Finally, it provides teachers with real-time feedback on student understanding, enabling them to adjust their teaching methods to meet the needs of their students.

The Dos of Cold Calling

To ensure that cold calling is effective and beneficial to students, teachers must adhere to some best practices. Here are some dos of cold calling in the classroom.

1. Establish clear expectations

Before implementing cold calling, teachers should establish clear expectations with their students. This includes informing students of the purpose of the technique, how it works, and the criteria used to select students. This ensures that students are aware of what is expected of them and how they will be assessed.

2. Randomize the selection process

To promote fairness and avoid biases, teachers should use a random selection process when cold calling. This ensures that all students have an equal chance of being selected and eliminates the possibility of favoritism or discrimination.

3. Give students time to think

When cold calling, teachers should give students time to think before answering the question. This promotes critical thinking and ensures that students provide thoughtful and well-reasoned responses.

4. Provide positive feedback

To promote confidence and encourage participation, teachers should provide positive feedback to students who respond to cold-calling questions. This reinforces positive behavior and encourages students to continue participating in classroom discussions.

The Don’ts of Cold Calling

While cold calling is an effective teaching technique, there are some don’ts that teachers should avoid to ensure that the technique is beneficial to students.

1. Don’t embarrass students

When cold calling, teachers should avoid embarrassing students by asking questions that are beyond their level of understanding or that put them on the spot. This can cause students to feel uncomfortable, which can negatively impact their self-esteem and willingness to participate in future discussions.

2. Don’t use cold calling as a punishment

Cold calling should not be used as a punishment or a way to embarrass students who are not paying attention in class. This can be counterproductive and discourage students from participating in future discussions.

3. Don’t overuse cold calling

While cold calling is an effective teaching technique, it should not be overused. Teachers should balance cold calling with other teaching methods to ensure that students remain engaged and do not feel overwhelmed.

4. Don’t ignore student feedback
