Description

Technical Field

[0001] The present invention relates to the technical field of digital tracking and evaluation, and in particular to a digital tracking and evaluation method and system for students' scientific literacy based on reinforcement learning. Background Art

[0002] At present, the digital tracking and evaluation system of students' scientific literacy is a method of evaluating students based on various verification indicator data in the process of cultivating scientific literacy. In the traditional scientific literacy evaluation system, the evaluation is often based on fixed standards and static data, which cannot fully capture the dynamic changes of students in the learning process. This "one-size-fits-all" evaluation method may not only ignore the individual differences of students, but also lead to over- or under-evaluation of some students due to the inability to adjust the evaluation strategy in time. The learning process of each student is a dynamic process. They will continue to accumulate knowledge, improve their abilities, and gradually form their own scientific literacy system in the learning process. Therefore, when evaluating students' scientific literacy, this dynamic change needs to be taken into account. Therefore, how to adjust the evaluation strategy in time according to the learning progress and performance of each student to ensure that the evaluation can always be close to the actual level of the students has become an important direction for the reform of the current education evaluation system. The Q-learning algorithm in reinforcement learning technology is a model-free reinforcement learning method based on the Markov decision process. It can learn a state-action value function (Q function), select the optimal action according to the current state, and update the Q function to gradually optimize the strategy. Combining the digital tracking and evaluation system of students' scientific literacy with reinforcement learning is an effective solution.

[0003] However, there is no digital tracking and evaluation method and system for students' scientific literacy based on reinforcement learning to adjust the evaluation strategy in real time according to students' learning progress, more accurately reflect students' actual scientific literacy level, and avoid over- or under-evaluation of some students.

[0004] Therefore, the present invention proposes a digital tracking and evaluation method and system for students' scientific literacy based on reinforcement learning. Summary of the invention

According to the verification indicator matrix of each student in each week, all the analysis weeks of each student in each week are obtained. The processed values ​​of all types of verification indicator data of each student in each week and the evaluation priority of all types of verification indicator data are obtained to obtain the verification indicator graph of each student in each week, and accurately draw a graphical representation of the overall evaluation of each student's scientific literacy in each week. Then, based on the verification indicator graph of each student in each week and the verification indicator graph of all analysis weeks, the digital evaluation score of each student's scientific literacy in each week is obtained, and the overall evaluation of each student's scientific literacy in each week is quantified.
