Learning experiences are activities planned by teachers to produce desired changes in student behavior and responses to stimuli. There are two types of learning experiences: direct experiences that involve firsthand interaction, such as seeing, hearing, or manipulating objects, and indirect experiences, such as reading or listening to lectures without direct interaction. While direct experiences are more reliable and long-lasting, indirect experiences are useful for developing imagination and are more time and cost efficient when firsthand experiences are not possible. The goal of any learning experience selected by the teacher should be to effectively meet the learning objectives.
