Abstract
Teaching is aimed to allow the language learners to practice developing skills. In our case it is vocabulary development. In incidental learning, the situations are chosen by language learners. This means that the language learners initiate the interaction by requesting the participation of a teacher. Most often, incidental learning is used in the study of foreign languages, and is considered here in this context. The learner’s request can be verbal or non-verbal: for example, he can reach for an object that is out of reach, damage his clothes, cry, call an a teacher by name, ask for a toy, food or information. This study demonstrated the effectiveness of the incidental learning approach.
