The functions of student rulers are diverse and diverse. In addition to basic measurement functions, some high-end student rulers are also equipped with special functions such as scale amplification and fluorescent display. The scale amplification function enables students to see the scale more clearly during measurement, improving the accuracy of the measurement. The fluorescent display function facilitates students to use the ruler in dimly lit environments, improving the convenience of use.

The use of teaching scale sets also requires attention to some issues. Firstly, the design of the measuring scale should be scientific and reasonable, with clear and specific indicators and appropriate scales to ensure the accuracy and effectiveness of the evaluation results. Secondly, when using a teaching scale set, teachers should follow the principle of objectivity and impartiality to avoid the influence of subjective assumptions and biases. Finally, the teaching scale set is just one of the evaluation tools and needs to be combined with other evaluation methods and techniques, such as observation, interviews, and work presentation, to obtain more comprehensive and accurate evaluation results.

The teaching scale set also has ease of use and flexibility. Teachers can choose or design a teaching scale set that suits their actual needs. In the evaluation process, teachers only need to score or rate students' performance based on the indicators and scales on the scale, which is simple and convenient to operate. At the same time, the teaching scale set can also be adjusted and modified as needed to meet the teaching needs of different subjects and grades.

The teaching scale set has a wide range of applications. It is not only suitable for classroom teaching, but also for various teaching scenarios such as experimental teaching and project practice. Whether it is the memory and understanding of knowledge, or the mastery and application of skills, the teaching scale set can provide effective evaluation methods. Meanwhile, the teaching scale set can also be used to track and compare student learning progress, helping teachers understand student learning dynamics and adjust teaching strategies in a timely manner.

The teaching scale set is a standardized measurement tool used to evaluate students' performance during the learning process. It usually includes a series of specific evaluation indicators, such as knowledge level, skill mastery, thinking ability, etc., each indicator has a corresponding scale or level, so that teachers can quantitatively evaluate the performance of students. This quantitative evaluation method enables teachers to have a more accurate understanding of students' learning status, thereby formulating targeted teaching plans and coaching strategies.
