Hur lärare kan stödja andraspråkselever på gymnasiet att tala kemi

In this study we investigate how two didactic models can be used by chemistry teachers to improve teaching to support students with a second language to “talk chemistry”. The study contributes to show how these models can be used by chemistry teachers to organize, perform and assess chemistry lessons in a way that better supports second language students to become more active in talking and so learn chemistry. The material consists of video and audio recordings from chemistry lessons in an introductory class in upper secondary school in Sweden. The study was carried out in two cycles of planning, teaching and analysis in two successive classes. The first cycle entailed analyzing how a “normal” chemistry lesson gave students opportunities to talk and learn chemistry. In cycle 2 changes were made by using the models for the purpose of increasing the students’ opportunities to “talk chemistry”. Our findings show how teachers can support also second language students’ learning to “talk chemistry” by using the didactic models developed for mono-lingual classrooms when planning and performing chemistry lessons
