The education process evaluation is composed of an education evaluation subsystem, a network operation subsystem and a reflection service subsystem, and a package solution is provided for implementation of the process evaluation. The following is presented in sub-system sections.
1. Education evaluation (real-time evaluation and assessment evaluation)
In view of the problems of discreteness of evaluation contents, singularity of evaluation modes, randomness of evaluation results and the like of the existing evaluation system, in order to solve the pain points and difficulties, the comprehensive student literacy evaluation method and technology which are complete, scientific and easy to operate are developed and designed to meet the needs of systematicness, completeness, scientificity and traceability of evaluation.
The technical scheme of the invention for education evaluation is as follows:
the examined contents are organized into the form of evaluation indexes, and the evaluation indexes are like operation questions and have question type attributes (such as question types of grading questions, selecting questions, non-questions or describing questions). The evaluation process can be summarized as: and a process in which the evaluation index is applied to the evaluation target by the evaluation client to form a result.
The specific operation steps are as follows:
A. making an evaluation rule and releasing the evaluation rule, wherein the evaluation rule is called as making an evaluation plan in a system;
B. according to the evaluation plan rule, executing evaluation and generating evaluation result data;
C. and pushing data such as the evaluation completion condition, the evaluation result and the like to terminals of related personnel and presenting the data.
In the evaluation rule making process, the step a further includes: filling in an evaluation form cover, selecting an evaluation mode, selecting an evaluation index, selecting an evaluation object, selecting a judge, making evaluation rules (such as whether to group or not, how to group and the like) of the judge, and automatically pushing the relevant information of an evaluation task to a judge terminal by the server to be presented after an evaluation plan is stored.
In the execution process of the evaluation plan, the step B specifically includes: and browsing my evaluation task by the evaluation client, executing evaluation according to rules, automatically storing an intermediate temporary result by the server, and automatically generating a formal evaluation result by the system after all evaluation data are formed.
The push presentation process, namely step C, specifically includes: the system automatically detects the completion progress of the evaluation plan, if the current progress is 100%, the system archives the evaluation results for query statistics, and pushes the evaluation results to terminal equipment related to an evaluation object.
In order to adapt to different business requirements, the evaluation business is divided into real-time evaluation and assessment evaluation, the real-time evaluation has the characteristics of instantaneity, randomness, high frequency and the like, the evaluation process can be simply described as selection indexes, an evaluation object is selected, evaluation is executed, and an evaluation result and result feedback are formed; assessment and evaluation need to be carried out by an assessment member after an evaluation plan is firstly made, so as to form an evaluation result, and the system pushes the evaluation result to an equipment terminal.
A system that refers to the above-described evaluation method, comprising:
the evaluation index maintenance module is used for maintaining (including adding, modifying or deleting) the evaluation index;
the evaluation service plan making module is used for making an evaluation plan by a system administrator;
the evaluation service execution module is used for executing a functional module for evaluating service operation;
the statistical analysis module of the student end is used for the index evaluation result of each student to look over, count and analyze the module;
the family member terminal statistic analysis module is used for reviewing, counting and analyzing the evaluation result of each child by the evaluation member;
and the evaluation result pushing module is used for pushing the evaluation result to parents, students or a comment equipment terminal.
Specifically, the method comprises the following steps: for real-time evaluation, the panelist selects an evaluation index → the panelist selects an evaluation object → evaluation is performed → evaluation data is formed.
For assessment evaluation, the administrator specifies an evaluation plan → the panelist performs evaluation → forms an evaluation result, and the evaluation process and the result data set will be different according to the selected evaluation mode, and we describe the evaluation result in detail below.
Our evaluation result is a three-dimensional linear space composed of triplets of evaluation indexes, judges and evaluation objects (students or teachers), which can be generally expressed as the following mathematical formula:
V(F)＝F[χ] 3 。
if i (index) represents the index, o (observer) represents the comment, and E (evaluated) represents the evaluation target, { E (evaluated) 000 ，E ioe Is one of its radicals, where ioe is the element subscript.
In order to meet the practical flexible and changeable realityIn the actual situation, we design 4 evaluation modes, which are respectively: evaluating the multi-evaluation assessment, evaluating according to indexes and evaluation groups, evaluating according to evaluation objects and evaluation groups and evaluating by single evaluation, wherein the former three are corresponding to assessment evaluation, and the latter one is corresponding to real-time evaluation; for the results formed by the evaluation of the multi-reviewer evaluation, we can refer to the result as the complete evaluation result set, namely the mathematical formula stated above. For the latter three evaluation modes, the evaluation result is a subset of the complete evaluation result, and if F represents the complete evaluation result set and S represents the result set of the latter three evaluation modes, then there will be a set mapping formula δ: s → F, if
I.e. there is a linear mapping σ as follows:
wherein, A represents a two-dimensional linear space composed of indexes and evaluation objects, o is an evaluation group element, and o =1 for a single evaluation mode.
2. Operating system (break established mode, artificial Intelligence (AI) based operating system)

The AI problem solving scoring module will integrate according to the flow shown in FIG. 7 and repeatedly execute this process until all the problems are resolved.
Standard score of subject
S is the total score of the question, and Wi is the weight of the answer item; since the student's answer sometimes does not match the standard answer in the system exactly, but the answer is correct, the existence of the similar answer is allowed, and the similar answer is scored
Wherein Wa is the weight of the similar answer in the standard answer score; if the calculation of the question may need the question solving process, the question answering process needs to be started, so the scoring formula with the question answering process S = SS + AS + PS; wherein SS is standard integral, AS is similar answer integral, PS is score of answering process, and S is final score of a certain question;
