Listening is critical to learning and an important part of the communication process. In a training institution some of the course material may be delivered through lectures, through audio, and through verbal instructions. Even with practical demonstrations and instructional videos, much of the content is delivered through the spoken word. If you are not fully involved in listening, you will miss some important information and can easily be distracted. On a job site, effective listening can be critical in ensuring the safety of you and your co-workers, and ensuring that a job is completed accurately and on time.
