The indexation of teaching objectives is to transform teaching objectives into specific indicators and standards, so as to quantify and evaluate the teaching process and teaching effect. Targeted teaching objectives can help teachers to better plan and organize teaching activities and ensure students to achieve the expected goals in the learning process. At the same time, the indexed teaching goal can also help students to understand the content and goal of learning more clearly, and improve the enthusiasm and effect of learning. Indexed teaching goals usually include learning goals, ability goals, emotional goals and values goals.
