CLIL classes Diverse researches have proved that there are profits in blending language learning and non-linguistic subject content. However, it is not just about using a language as a mean of instruction but using a new method to reach the goals in both contents and language matters. Several initiatives based on this new methodology has been grouped under the term CLIL (Content and Language Integrated Learning). In CLIL classes, learners don't only read a text to learn language but to acquire insights into the non-linguistic subject. Besides, CLIL approach takes into account the learning skills of each learner, whereby lessons have to be designed with this triple focus. Language as a support of content and appropriate activities to the different students' needs and abilities. In addition, educational objectives are structured in a hierarchical way. Questions and activities should be link with other set of materials of higher difficulty. In this way, students will engage actively to their learning, evaluating their outcomes and progress, while teachers will take a role of guide or facilitator of the knowledge needed by the students to achieve each level. Obviously communication plays a fairly important role, so students need a safe learning environment in which they feel confident to experiment with the language. Strategies to achieve this could be for example, glossary of terms or discourse patterns. Although one of the most effective is to develop materials that arouse the interest of learners. CLIL issue can be both challenging and demanding for teachers and students, but it can be also stimulating and effective, for these reasons this strategy should be include in the repertory of every good teacher.
