Development of Teaching Polymer Chemistry Test Question Database System Huang Meirong, Li Xingui (National Key Primary Interface of Concrete Materials of Tongji University. Open the document (you can open the rf document directly into the interface) cut, copy, paste (the same word), followed by the font processing tools, are similar to the word, as well as modify, add, delete button, the corresponding test bank can operate . Test paper generation is the core, divided into manual and automatic parts, look at the automatic part. Click on the "Auto" button on the main screen to get the filter title interface. If the default is all questions, all topics, click OK will display all the questions in the database (see). If you select the question type and custom theme, you can filter the questions. Click “Next†to list the selected questions in the desired chapter. Use the mouse to select to view topics and answers. Enter the number of questions the user wants in the form, and click Next to generate an aesthetic test that meets the requirements. In the “Test Paper†form, you can edit the format of the generated test paper, save it, etc. operating. Click "Answer" to view the answer sheet, and the "Answer" form can also perform various editing operations. The manual part is similar to the automatic part. The left side is a form from which to extract the user's desired question, and then click OK to generate the test paper. The operation is the same as automatically generating the test paper part. An interface in the automatic generation of the test paper 2 Analysis of the test paper Click the "Analysis" button on the main screen to get the interface shown. Below the menu are 3 commonly used buttons. First is the “New Test Paper Analysisâ€. Click on it to enter the editing status. Next is the “History Check Referenceâ€. You can view the previously saved analysis records, and finally print the results. Analysis Table. When you perform a new test paper analysis, after filling in the header, there will be a form line just below the number of students and the number of questions. After each student's corresponding topic's results are entered into the form one by one, the score of the title itself (standard Points) Enter the corresponding place in the lower part of the table and click OK to display the analysis result. The analysis results have average scores, standard deviations, degree of difficulty, proportion of the number of segments, and can be saved. 3 Data query Click the "Data" button on the main interface to get the main interface of the query. Under the menu is a radio button, the default is one, click the "Read" button, the data content will be displayed. The box on the right is "Custom Search". After selection, you can select the data you want to read according to the user's requirements. The search conditions include: title, author, keyword, source, etc. The search condition is a complex option. After filling in one or more conditions, click the "Show" button to call up the list of data topics that you want to meet the search criteria. Select an article of interest and click "Read" to display the full text. 7 questions bank system software features 7.1 pertinence strong This software is written for the polymer chemistry course, the design process closely linked to the teaching content of polymer chemistry, taking into account the chemical formula and other specialization in the symbol of high school processing and access, while Combined with the knowledge structure of polymer chemistry, a question bank was designed. So it can be well applied to high-level teaching. This kind of strong pertinence is not available in other software. For example, the inorganic study question bank developed by Wang Zhiqiang and others of Nanchang Normal University is written in the OLE field of ACCESS. It is not convenient to handle some organic chemical symbols or pictures. Although a variety of exercise software is currently available, there is no report on the polymerized test bank. 7.2 Fully-featured This problem bank system is full-featured, from entry, deletion, modification and interviewing of topics, to the manual or automatic generation, printing and statistical analysis of the papers, and to the reading of data, etc. Online online, but at least to help users complete most of the work within the scope of the paper. 7.3 Question Bank Large Question Volume This problem bank is a set of exercises that have been precipitated during the years of teaching accumulation. The topics were collected under the guidance of a senior professor who had many years of experience in polymer chemistry teaching. There are various types of questions, including various questions of difficulty, yes and no questions, multiple choice questions, blank questions, concept questions, derivation questions and calculation questions. The contents cover all chapters of polymer chemistry, such as radical polymerization, free radical copolymerization, and ionization. Polymerization, living polymerization, coordination polymerization, linear condensation polymerization, bulk condensation polymerization, and polymerization method. Some of them come from in-class exercises, some come from extracurricular books, some come from the mid-term and final period examination papers, and others come from postgraduate entrance examination papers. There are hundreds of questions in the entire library, and the classic answers to the questions are accurate. This can produce high-quality papers. It is currently the closest and most practical teaching software for teaching in polymer chemistry. 7.4 Easy Maintenance The software is developed using VB. Compared with other programming software, VB is not only easy to understand, but also has room and convenience for software maintenance and subsequent development. This is not possible with other development tools. The software uses ODBC as a database interface to make the software interface separate from the database physically. And the logical separation greatly facilitates the maintenance and repair of users. ―. If you need to create a problem-solving library for other courses, you only need to create the database for the course database, and then use the software interface through the link.
