21st century students need to acquire intellectual skills and abilities to function effectively in an environment that requires working with others to accomplish a variety of tasks. Using cooperative learning, teachers help students lay the foundation for success in a world that relies on cooperation. For this to happen it is important to have positive interdependence and individual responsibility. Positive interdependence emphasizes that everyone strives together and that one person's success does not come at the expense of another's success. It is important for teachers to ensure that the work of each group member is significant to the success of the task. Individual accountability refers to the need for each team member to receive feedback on their efforts to contribute to the goal. Cooperative learning allows students to interact so they can improve and deepen their learning. Students can reflect on the knowledge they have acquired by talking and listening to their classmates. It also increases motivation to learn because it encourages responsibility, can improve cognitive and social skills, such as academic engagement, self-esteem, attitude towards school and a strong affinity with peers. Some recommendations for using cooperative learning are: Include elements of positive interdependence and individual responsibility: Students are able to interact on a deep level. Using this strategy, students are responsible for their own learning, the learning of their group members, and the ability to demonstrate what they know, understand, and can do. Keep group sizes small: For more successful group work, the size of the groups should be... half the size of the paper... telling them that everyone is responsible for their own learning. Assign roles to each group member who will help complete the task.2. Teachers can use formative and summative assessments to determine student contributions to the group goal.3. Cooperative learning increases motivation to learn because students establish a sense of mutual obligation and a strong affinity with their peers that leads to greater motivation and greater achievement.2 Questions:1. How can lower grades apply the cooperative learning strategy? What activities can be carried out to apply the strategies from primary school to third grade?2. How can we integrate students who don't have the social skills to work in groups? I liked the idea of ​​assigning students to groups randomly or based on a variety of criteria (interests, month of birth, colors they wear, etc..).)
