4. Conclusion This article describes an innovation in teaching and learning through problem posing tasks and metacognition strategies. In order to active of metacognition skills, educators can change the learning environment and provide new and alternative tasks that help pupils to think about subject material, its organisation and its manipulation in ways they had previously not considered. Teachers can generate these tasks based on teaching and learning objective related to particular subject and content by problem posing situations. Furthermore, they can lead learners to applying relevance strategies for generating new themselves problems in an active learning environ appropriate metacognition level. These conditions can encourage peers to discussion together or their teacher and query in which they are asked to engage with adequate levels of control cognitive processes. It can be recommended implementing problem posing and metacognitive activities in science classroom, due to can facilitate successful learning and establish high levels of emotional support and trust between the teacher and students in complex subjects of science.
