Tidigare forskning visar att om lärare utformar NO-lektioner med inslag av kritiskt tänkande, skapar elever ett större positivt intresse till undervisningen och attityderna förändras till dess innehåll. Syftet med studien är att ta reda på hur NO-lärare arbetar med att utveckla elevers kritiska tänkande samt om de kan använda färdigt material. Semistrukturerade intervjuer har genomförts med sex olika mellanstadielärare och det visade sig att lärarna använder tre strategier för att nå dit, vilka är repetition, progression i olika NTA- laborationer samt skriva kritiska frågor och arbeta utefter EP A-modellen. Studien visar att de intervjuade lärarna anser att det är viktigt att utveckla elevers kritiska förmågor och lärarna arbetar aktivt med detta på lektionerna. Avslutningsvis framhåller studien att lärarna aktivt behöver arbeta med elevers kritiska tänkande och med NTA-materialet, samt att Concept Cartoons hjälper läraren i denna process. / Previous research shows that if teachers design their science classes with elements of critical thinking, pupils’ create a greater positive interest in the teaching and attitudes change towards its content. The purpose of this study is to find out how science teachers work to develop pupils' critical thinking and whether they can use ready-made material. Semi- structured interviews have been conducted with six different middle school teachers and it turned out that the teachers use three strategies to get there, which is repetition, progression in different NTA laboration and writing critical questions and working according to the Think- Pair-Share model. The study shows that the interviewed teachers believe it is important to develop pupils' critical abilities and the teachers work actively with this during class. In conclusion, the study highlights that teachers need to actively work with pupils' critical thinking and the NTA-material and Concept Cartoons help the teacher in this process.

AbstractThe purpose of the present study is to find out how three high school teachers with different subject skills use interaction and interplay in their teaching. The main part of the study is based on observations of six different class sessions in history, religion, Swedish as a second language and regular Swedish. The study also includes interviews with the sessions’ corresponding teachers. The final analysis focuses on the forms of teaching, where the focus is on interaction and interplay, as well as multimodality in teaching contexts. The result is compared to the Läslyftet modules that relate to interaction and interplay, and also multimodality for the purpose of language development. The results show which interactive and multimodal strategies are used when interacting with students. Furthermore, the results show interest and commitment, as well as learning potential, potential support by applying explanations, clarifications, discussions, conversations, the Think-Pair-Share model part and the Initiate-Response-Feedback pattern (IRF) to enable students to reformulate to written language style and recontextualize their responses. In this way, knowledge and language development have been made visible in ongoing teaching.
