Task-based teaching in primary school mathematics unit teaching is embodied in the following ways.
1. Set task objectives: At the beginning of each large unit, teachers can define the task objectives, that is, the academic performance and ability requirements that students need to achieve in this unit. It is helpful for students to make clear the direction and goal of learning.
2. Providing task context: Teachers present specific task background to students by setting context or introducing questions. This task situation stimulates students' interest in learning and applies mathematics knowledge to real life.
3. Break down the task steps: break down the big task into smaller task steps and gradually guide students to complete the whole task. Teachers provide clear guidance and demonstration to help students understand the requirements of the task and how to complete the task.
4. Guide cooperative learning: encourage students to carry out cooperative learning, group cooperation or partner cooperation in tasks, and * * * solve problems and complete tasks. Promote the communication and cooperation between students and improve the effect of solving problems.
5. Provide feedback and evaluation: After the task is completed, the teacher provides feedback and evaluation in time to help students sum up experience, find shortcomings and provide further guidance. It is helpful for students to reflect and improve their study.
Task-based teaching is a task-centered teaching method, which guides students to actively explore and solve problems and promotes the development of knowledge and ability by providing students with specific tasks.
