Create a relaxed learning atmosphere. A quiet environment with no traffic, comfortable chairs, and no direct light shining on the computer screen creates a feeling of safety and security. In any learning task, the inherent internal pressure to perform remains, but it can be alleviated somewhat by environmental comfort. When the computer seems more approachable or less threatening, the learner can absorb far more material in a shorter period of time.
Provide a verbal and written outline of your purpose and method. A road map makes a journey more comfortable. Letting trainees know what they are going to do, how they are going to do it, and what your goals for their learning may take time, but it sets the stage and better prepares the learners. Any perceived secrets or surprises start to dissipate when this preparation is provided.
