Problems solved by technology

Existing candidates' experimental operation tests usually require multiple teachers to invigilate and observe the experimental operations of several candidates at the same time. After the candidates complete the experiment, the teacher will evaluate and score the candidates on the spot. The scoring results are subjective and difficult to

example 1

[0095] Example 1: Explore the water absorption and water loss experiments of plant cells

[0096] This is a typical biological experiment in the textbook: it not only uses a microscope, but also cultivates students' ability to explore. In view of the requirements of the test time for the experimental operation, this case only selects the part of exploring water loss for research.

[0097] The data acquisition system developed in this case uses sensors to detect the use of materials and reagents, the drainage operating environment, and the recognition and processing of microscopic images. Evaluate students' basic abilities in making temporary mounts, using microscopes, operating essentials of drainage method, and accurately identifying the plasmolysis state of cells. According to the above situation, the experiment can be divided into various experimental steps, and the standard experimental procedure data of each experimental step is stored in the database.

[0098] The step...

[0104] Example 2: Detection of carbohydrates, fats and proteins in biological tissues

[0105] The data acquisition system developed in this case uses sensors to detect the use of reagents, collects and compares the color changes of tissue samples before and after the reaction. Examine students' mastery of knowledge and skills such as the organic components contained in biological materials, the selection and use of detection reagents, and whether the color reaction is correct. In view of the requirements of the existing case 1 research and the test time of the experimental operation, only the detection of organic matter in biological materials is explored.

[0106] The system can also be used for other reagent color reaction experiments, such as the detection of alcohol produced by yeast fermentation, the identification of crude DNA extraction; it can also be used for self-made acid-base indicator, test of solution acidity and alkalinity, properties of phenol and protein Che...

Abstract

The invention discloses an experiment operation evaluation method and system based on a DIS, and the method comprises the steps: obtaining a plurality of pieces of experiment step data of an experiment operation performed by an examinee; comparing the plurality of pieces of experiment step data with the corresponding standard experiment step data to obtain the similarity between each piece of experiment step data and the corresponding standard experiment step data; carrying out the weighted calculation of the similarities between the pieces of experiment step data and the corresponding standard experiment step data to obtain the test score of each piece of experiment step data, and carrying out the accommodation of the test scores of the pieces of experiment step data to obtain an experiment result; and outputting the experiment result. According to the technical scheme of the invention, the method can achieve the automatic scoring of the experiment operation steps of the examinee, andimproves the work efficiency. The method is more accurate in scoring, and brings convenience to the examinee and parents for subsequent checking.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a DIS-based experimental operation evaluation method and system. Background technique [0002] With the continuous development of electronic information technology, the teaching evaluation system has made great improvements. Most of the current teaching evaluation systems only calculate and score candidates' paper-and-pencil test papers, and lack of judgment on students' calculation process. The above-mentioned system is not suitable for testing the experimental operation process of candidates. Existing candidates' experimental operation tests usually require multiple teachers to invigilate and observe the experimental operations of several candidates at the same time. After the candidates complete the experiment, the teacher will evaluate and score the candidates on the spot. The scoring results are subjective and difficult to be objective and fair. The basis for error...
