The purpose of the lesson introduction is to engage learners with a new learning content and to stimulate their interest. Successful lesson introductions introduce learners to the central aspects of the new topic. The teacher connects to the learners' prior knowledge and often enables a hands-on approach to the new topic. For the lesson introduction to be successful, the teacher must spark interest in the new topic, inform about what is to come, create a connection between the known and the new learning material, and activate prior knowledge and experiences. Additionally, the teacher should give learners a chance to plan and determine the next steps together. To foster a successful willingness to learn at the beginning of the lesson, a good teacher-learner relationship must be established, as it can have a significant impact on the learners' motivation. To motivate learners, a variety of engaging and innovative introductions are necessary. In this book, you will find practical ideas for implementing different lesson introductions.
