as a teacher, are you still worried about correcting a large number of objective questions (student homework)? The method of this article may help you solve problems. The following system home Xiaobian will share with you the ordinary computer review! It is easier to read the papers. Limited to the actual situation of shortage of education funds, it is almost impossible for schools, training institutions, and test centers to achieve paperless examinations in one step. The purchase cost of the computer scoring system for the college entrance examination or the national level examination is not borne or willing to be borne by each teacher or school. So is there a way to quickly improve the efficiency of marking, while reducing manpower and financial expenses? There is a way! That is the ordinary computer review. Just a normal camera (or digital camera, scanner, digital camera, etc.), plus a small software, you can easily and quickly read the volume, and can immediately rank, statistical analysis results. No need for a dedicated marking machine and a dedicated answering card, you can achieve the objective title unified scoring. The answer sheet can be set in the embedded test paper, no special paper and separate printing, only ordinary paper or copy paper can be used, which effectively reduces the cost. First, the computer marking requirements and answer sheet scanning is of course not a random test paper (answer card) can use the computer to check the volume; to use the computer to read the paper, the examination paper, test paper production, answer sheet and answer sheet on the test number are certain Rules or requirements. (1) The computerized test papers must have all the objective questions (ie, multiple-choice questions, judgment questions) in order to realize computer scoring, while subjective questions such as composition can only be reviewed by workers. There are also the number of questions in the objective test papers, and the options for multiple-choice questions must be matched with the answer sheet. If the order number of the 100-question answer sheet is 1, 2, 3 to 100, then the question number and answer for the test paper production requirements. The order of the card title numbers must be the same, that is, the order of editing each question number of the test paper is also 1, 2, 3 to 100; this is mainly to let the candidate understand that the test title number corresponds to the answer number of the answer sheet, and know which answer sheet Answer the question. In addition, the test papers should also be written clearly to answer the requirements of each type of big questions, such as the judgment requirements: "correctly painted "A & rdquo;, error painted "B”” and other words to let candidates understand the answer requirements, a complete The test paper production requirements (Figure 1). (2) Computerized answer sheet production requires that the computer review papers are mainly used to read the answer sheet through the computer, so the answer sheet must use the answer sheet style (or template) provided by the marking software. Not all answering cards use a marking software. Can read correctly. PC OMR 9.0 software comes with a variety of answer sheet styles. We only need to set the answer sheet according to the number of questions and the options of the multiple choice questions, that is, the options of the multiple choice questions. If the option of the multiple-choice question is up to the E option, it is impossible to use the answer sheet option up to the answer card of D. Otherwise, the E answer has nowhere to answer; select the corresponding answer sheet according to the above two points, and use ordinary printing paper. Or copy paper can be printed or copied directly. Of course, the answer sheet can also be modified briefly. For example, adding some notes on the answer sheet at the top of the answer sheet will not affect the normal use of the answer sheet (Figure 2). (3) The answer number of the answer sheet requires that the computer can only identify the test number, and cannot identify the name. That is to say, each candidate must have a special test number, so each candidate must be assigned a corresponding test number before the test. Corresponding to its name, in order to allow the candidate to correctly fill in the test number on the answer sheet, and the scores of the test number will be known to know who is the score. The answer number used here is four digits. Under normal circumstances, both the student and the trainee have the student number or the admission ticket number, which can be used as the test number, so just tell the candidate to use the student number or the admission ticket number. A few digits are used as the test number on the answer sheet, and the correct answer sheet can be applied on the answer sheet. The data of the test number and name should be used when reading the computer. These data are generally available, even if there is no current work, it will take a few minutes. (4) The answering card scanning computer scoring is through the scoring software, reading the answer sheet to achieve the purpose of scoring, then the answer card that the candidate answers, through the ordinary camera (or scanner, there is a high-speed scanner is better), will answer the card All scanned into a picture and stored in the computer, used as a next step to prepare for the review. Because the amount that the author has reviewed is in large quantities, the scanning and scoring operations are performed separately. Of course, the speed of the answering card scanning speed depends on the scanning device used. If the speed is scanned by the high-speed scanner, it is like the speed of the banknote counting machine. Everyone knows how fast it is. The speed of natural scoring is faster, because the speed of computer scoring depends mainly on the speed at which the answer card is scanned into a computer. In fact, no matter what scanning device is used, scanning the answer sheet into a picture and saving it to the computer is much faster than manual review. As for the scanning method, different devices adopt different methods, and the answer sheet image format can be BMP format or JPG format. In the past few years, the amount of corrections (about 100,000 copies a year) has been used by high-speed scanners and supporting scanning software. Scan mode uses "black and white", the resolution can be 150 resolution, so the scanning speed is faster, and it will not affect the recognition rate of the answer sheet; the answer sheet picture format is mainly used in the BMP format, which is convenient for later review. “Drawing" software, the answer card for the wrong test number is modified. Second, using the computer to read the software batch reading answer card to do the above preparations, the next step is to use the marking software PC OMR 9.0 to scan the answer sheet in batches. The steps are as follows. To make a standard answer, first make a standard answer and assign a score. There are two ways to answer the standard answer. One is to use Excel to make a standard answer, copy and paste it into the PC OMR marking software and save it. Using Excel spreadsheets to make standard answer forms is as simple as three columns: one for the question number, one for the answer, and one for the score (Figure 3). After making the answer, open the PC OMR marking software, select the "answer" and "number" of the standard answer of the Excel form and copy it, then select the marking software "Paste from Excel" and paste the answer to It can be saved in the PC OMR marking software (Fig. 4). This method is suitable for large-volume marking, that is, others provide good Excel answers. Another standard answer is to open the PC OMR marking software directly and select “Select the test paper”. The practice is similar to the previous one, but it is not “Paste from Excel”; instead, select “Insert” line, then Enter the answer manually and assign it to the score, and save it. Add the candidate's roster first select the “Certificate Roster” in the software, and then copy the two pre-existing rosters of Excel, ie, “Test No.” and “Name”, and then select the “Record” in the software. Excel paste & rdquo; and save it. If the amount of correction is large, and the roster is to be replaced at any time, then the roster can be pasted in, no need to save, so the next time you change the roster, just select the “candidate roster” option, the original roster will be automatically cleared, no need to Go and delete it separately. Perform the marking selection "checking" option, then select “answer card batch review” option, import the previously scanned answer sheet image for batch review, after importing the answer sheet, you can see the corrected results ( Figure 5). If you read the test number and fill in the wrong question during the marking process, if the candidate forgets to apply the test number, or draw one less, or the test number is filled with the wrong position and the other test number is repeated, the software will be in the corresponding answer sheet picture. In the row, the red shading is automatically marked and the error is displayed in the “Checking Case” column. For this part of the answer card, if the answer sheet is selected, you can click ““Modify Image” to open the “Drawing” software and other software to correct it and then read it again. After the score management is completed, you can view the scores of the candidates and detailed score analysis, and you can export the scores and analysis to Excel or Word at the same time, and use them for further analysis and analysis.
