Description
Technical Field
The invention relates to the field of internet, in particular to a teaching system based on chemical principle experiment courses.
Background
The chemical industry is one of the important post industries of national economy and is also the energy strategic post industry of the country; the chemical principle is a professional core course of chemical engineering and pharmacy, is a basic technology course which is necessary to be repaired by the professions of chemical engineering and technology, environmental engineering, pharmaceutical engineering, light engineering, macromolecules, applied chemistry, food and the like, and relates to various fields of agriculture, medicine, food, energy and the like. The chemical principle experiment is an important component of a chemical principle course, is an important way for combining theory and practice, is an important link for culturing the animal activity and innovation of students, and is a necessary course for relevant research of chemical engineering. It belongs to the field of engineering experiment and is also the beginning of engineering practice teaching. The course mainly introduces a typical unit operation experimental process shared in the chemical production process, also relates to other related industries, and plays a very important role and significance in the chemical industrial production.
The chemical principle experiment is used as a professional basic course for chemical engineering and process major, and an experiment course is independently set. The purpose of the chemical principle experiment is to consolidate and deepen the theoretical knowledge of the chemical principle course and master the professional experiment technology and the experimental research method of the chemical principle. The course content includes experimental portions of the individual unit operations that are closely related to the chemical principles course. Through the learning of the course, students master the basic technology and the operating skill of the chemical principle experiment and master the basic method of the chemical principle experiment research, the understanding of the transmission process is deepened, the abilities of the students to engage in the experiment research and the abilities of training the students to analyze and solve problems are developed, the students are enabled to form the learning attitude of theoretical connection with reality and seriousness, and the independent thinking ability and the innovation ability of the students are improved. The capability of students in experimental scheme design, equipment operation, engineering actual problem processing, division work cooperation and report writer can be improved through chemical principle experimental teaching.
Practice teaching is always an important link of chemical and chemical course teaching, and draws high attention to various colleges and universities throughout the country. At present, the course examination mode of the teaching method of the national chemical principle experiment is generally based on an off-line experiment, the experiment is carried out in a mode of 20% of ordinary results + 80% of experimental reports, some colleges and universities also carry out 20% of ordinary results + 40% of experimental reports + 40% of theoretical examinations, some introduced virtual simulation enters the experiment, and the mode of 20% of ordinary results + 40% of experimental reports + 20% of simulation operations + 20% of theoretical examinations is carried out. The Tarim university is mainly performed in a mode of 20% of ordinary achievements + 80% of experimental reports, and is performed in a mode of 20% of ordinary achievements + 40% of experimental reports + 40% of theoretical exams in a small amount.
In a traditional mode, educational resources are gathered in a relatively closed physical space of a campus, are limited to places such as classrooms, libraries, laboratories and the like, and meet the requirements of fixed people; and the dependence of students on the teaching of teachers is obvious. The practical operation process of students is difficult to assess, and the difference of experimental operation of each student can not be distinguished. The students have different bases, classification teaching cannot be realized, and the difference of the assessment scores cannot be realized. Practice courses are generally used for examining practical and manual abilities, some practice courses are still in a mode of examining and determining the lifetime, and the course teaching and examination targets are difficult to embody in the form of experimental reports and theoretical examinations at present. A large number of students have a coping attitude, namely a walking process, the students can pass through the learning process after considering the inversion, and the learning enthusiasm is not high. The modernization degree of the experiment is not high, and the experiment does not reflect the application of the scientific and technological achievements of the new era in the modernization teaching. The assessment standard is not unified and accurate, and the teaching content cannot be reflected in the assessment system. Few designed and innovative experiments and no accordance with the culture target of modern innovative talents. The virtual simulation experiment is only used as a preview, and the modern teaching achievement does not play the original role in teaching. Students cannot master the progress of experimental results at any time and adjust the experimental process, the learning method and the attitude in time.
