T E A C H I N G THROUGH A FOREIGN LANGUAGE Many of these experiences and discoveries can be taught through the L2 without hindering the learner’s comprehension of concepts. In the first learning year children are introduced to the foreign language via topics such as pets, fruits and vegetables, spring flowers and summer sports. Later on in the CLIL programme the topics can be expanded to include experiments with water and magnets, observations of weather and the biological development of the frog or butterfly. CLIL in the first years emphasises listening and speaking skills, whereas reading and writing are introduced later in the curriculum. As teaching through the L2 is a communicative approach to language acquisition, explicit grammar teaching does not play any role at this stage. 3.3 Length and type of exposure Some CLIL research has indicated that CLIL has a relevant impact when the foreign language is used for at least 25% of a lesson, in one or more subjects, or in interdisciplinary projects. The foreign language can be used in different situations, preferably planned in advance: • in the same subject, some lessons can be taught in the L2, others in the mother tongue on the basis of the specific topic, and the kind of mate- rials and interaction activities available • some teachers prefer to introduce new concepts in one language and use the other to revise them later. It is important to define the reason for dif- ferent strategies and to be aware of different policies in this regard. For example, the L2 can be used more for receptive skills, both oral and writ- ten. In the primary school, the foreign language is mainly used for oral activities. 93
