Embodiment 1

[0032] known parabola with straight line Intersect at two points A and B (point A is on the left side of point B). The vertex of the parabola is C, and the CD∥x axis passes through C, and intersects the straight line AB at D. Calculate the area of ​​△ABC (see attached figure 1 ).

[0033] (1) Let's look at the answering process of this question, and divide it into thinking group modules as follows:

[0034]

[0035]

[0036] The score point is the key point for calculating the thinking sub-module of this question. Without this joint point, the content of the next node cannot continue to be calculated. Therefore, use the computer to judge the process of answering the test and grasp these nodes to judge right or wrong. I will judge the correctness of my overall process.

[0037] (2) Judging the questions according to the key points of thinking, you can also set the interference background to change the structure of the test questions into multiple-choice questions wit...

Abstract

The invention discloses an intelligent system for automatically judging mathematical and physical subjective questions, which belongs to the technical field of education evaluation. Starting from changing the structural form of subjective questions, the system not only ensures that the changed subjective questions and the original subjective questions have the same test effects of mastering the knowledge of students, developing the disciplinary ability, flexibly forming applied knowledge and the like, but also adapts to the identification technology of a computer.The test questions can be quickly and accurately judged. Meanwhile, an interference item is arranged at a score point, an interference background is added, and the structure of the test questions is changed into a multi-step combined choice question. According to the operation technology for achieving braked question judgment by changing the structure of the test questions, through practical application tests, when the same students with the same knowledge content and the same subject ability are tested, the test scores of the students have no obvious difference or no difference.

Description

technical field [0001] The invention relates to an intelligent system for automatically judging subjective questions of mathematics, physics and chemistry, which belongs to the technical field of educational evaluation. Background technique [0002] With the deepening of educational reform, the function of educational evaluation is becoming more and more complete, and the process of educational development has pushed the issue of educational evaluation adapting to the needs of modern education to the front of the overall reform of education. It must be resolved without delay. The scoring efficiency of subjective questions is low, and multiple grading people participate in grading, so it is difficult to unify the mastering standards. Since the evaluation of subjective questions is carried out manually, the marking process is relatively long. To obtain more detailed and in-depth analysis results of the paper, the time will be longer. The educational evaluation lags behind the...
