Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of teaching, and relates to a method for children's listening vocabulary learning. Background Art
[0002] English is an international language and a necessary skill for people working in scientific research, foreign trade, etc. At present, a method of learning English by reading original books is very popular among parents. The process is: (1) master 3,000 listening vocabularies; (2) read graded reading materials and convert listening vocabularies into reading vocabularies through natural spelling; (3) read chapter books. The ultimate goal is to make children like reading and reach the reading level of their native language.
[0003] The accumulation of listening vocabulary in the first stage is the key point of this method. If you rush into the second stage, even if the child spells out new words, he or she will not be able to understand them. Staying in the second stage for a long time will seriously dampen the child's interest in reading and prevent him or her from reaching the reading level of his or her native language.
[0004] However, the first stage is also the difficulty of this method. For ordinary families in China, it is difficult to complete the first stage. Limited by the English level of parents, children can acquire about 500 listening words through pointing and TPR, and can acquire about 500 more listening words through parent-child reading. After that, the learning efficiency of children will drop significantly, and the reasons are as follows:
[0005] (1) It is difficult to choose appropriate learning materials. The 5-finger principle is popular abroad for choosing appropriate reading materials. However, this principle is not suitable for choosing listening materials. On the one hand, it is difficult for children to hear how many words they do not understand, and on the other hand, parents do not know which listening vocabulary their children have mastered.
[0006] (2) A large portion of the words that parents select for daily learning are already mastered by their children. When a child’s listening vocabulary exceeds 1,000, it becomes difficult for parents to figure out which words are new to their children.
[0007] (3) Not knowing when and which vocabulary to review. If you don’t review in time, the vocabulary you have learned will easily be forgotten.
[0008] (4) It is difficult to determine when the first stage will end.
[0009] In summary, there is currently no tool to accurately count listening vocabulary, and the vocabulary obtained through estimation methods has large errors. Summary of the invention
[0010] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose a method for children's listening vocabulary learning. The technical problem to be solved is: how to accurately count the vocabulary of children and help parents improve the learning efficiency of children's listening vocabulary.
[0011] The purpose of the present invention can be achieved by the following technical solutions: A method for children's listening vocabulary learning, comprising the following steps:
[0012] S1, adding words to be learned in the vocabulary learning table and learning the words to be learned in the vocabulary learning table;
[0013] S2, recording the state parameters of each vocabulary word after learning, wherein the state parameters include being able to speak, being understood, being forgotten, and not being learned;
[0014] S3, performing image recognition on the vocabulary learning table with recorded state parameters, identifying and obtaining the words and state parameters of each vocabulary to be learned in the vocabulary learning table;
[0015] S4, creating an entry for each recognized word and its corresponding state parameter and recording it in today's listening vocabulary list, and recording the learning date, word frequency sequence number and review interval in each entry;
[0016] S5. Traverse each entry in today's listening vocabulary list, compare the words in each entry with the words in the listening vocabulary master list, and when the word compared with today's listening vocabulary list is retrieved in the listening vocabulary master list, modify the state parameter and learning date corresponding to the word in the listening vocabulary master list, and modify the review interval according to the state parameter; conversely, when the word compared with today's listening vocabulary list is not retrieved, store the entry corresponding to the word in the listening vocabulary master list.
[0017] The working principle of the method for children's listening vocabulary learning is as follows: when teaching children through the method, first add the vocabulary to be learned in the vocabulary learning table. The addition of the vocabulary to be learned can be manually filled in by the parents or directly generated by the system. When learning vocabulary according to the vocabulary learning table, the parents record the state parameters of each vocabulary to be learned according to the learning situation. If the words of the vocabulary can be said, the state parameter is recorded as being said. If the vocabulary is forgotten, the state parameter is recorded as being forgotten. The recorded state parameters also include understood and not learned. After the learning is completed, the vocabulary learning table with the recorded state parameters is image recognized to recognize the words and state parameters of each vocabulary to be learned. Then, the recognized words and the corresponding state parameters are created as an entry. The entry also records the learning date, review interval and word frequency sequence number. All entries are recorded in today's listening vocabulary table. Finally, the entries in today's listening vocabulary list are traversed, and the words in each entry are compared with the words recorded in the listening vocabulary list. If the compared word is retrieved in the listening vocabulary list, the state parameter and learning date corresponding to the word in the listening vocabulary list are modified, and the review interval is modified according to the state parameter. If the compared word is not retrieved in the listening vocabulary list, the entry corresponding to the word is recorded in the listening vocabulary list. When learning next time, the vocabulary to be learned is automatically added from the listening vocabulary list to the vocabulary learning list according to the learning date and review interval. This method can help parents accurately grasp the vocabulary learning situation of their children, and make their children learn vocabulary in a planned way, which greatly improves the efficiency of their children's vocabulary learning. In addition, this method can accurately count the listening vocabulary mastered by children, and help parents accurately know their children's reading level.
[0018] In the above method for children's listening vocabulary learning, in step S1, the operation of adding vocabulary to be learned in the vocabulary learning table includes:
[0019] When there are entries in the listening vocabulary list, extract the vocabulary to be learned from the listening vocabulary list into the vocabulary learning list according to the learning date and review interval recorded in each entry, and print the vocabulary learning list;
[0020] When there is no entry in the listening vocabulary list, add the vocabulary to be learned to the vocabulary learning table and print the vocabulary learning table or print a blank vocabulary learning table;
[0021] Add the vocabulary words you want to learn by handwriting in the spaces on the printed vocabulary study sheet.
[0022] After one study, multiple entries will be recorded in the listening vocabulary list. After that, you can select the vocabulary to be learned from the listening vocabulary list according to the recorded learning date and review interval, such as selecting vocabulary whose learning date plus review interval is equal to or less than the current date as the vocabulary to be learned. After the selected vocabulary to be learned in the listening vocabulary list is placed, you can also add new entries on the remaining blank lines independently, such as adding them by hand after printing out the vocabulary learning table, or inputting them by keyboard on a mobile phone or computer. When this method is used for the first time, the entries in the listening vocabulary list are blank. At this time, you can directly print a blank vocabulary learning table and add vocabulary to be learned by handwriting, or you can input the vocabulary to be learned by keyboard on a mobile phone or computer and then print the vocabulary learning table.
[0023] In the above method for children's listening vocabulary learning, in step S1, when selecting the vocabulary to be learned from the listening vocabulary list to the vocabulary learning table, it also includes: sorting the selected vocabulary to be learned according to the recorded state parameters, sorting the vocabulary to be learned with the state parameter of unlearned to the first position of the vocabulary learning table and highlighting the vocabulary to be learned. Such operation can make children learn the unread vocabulary first, reducing the number of unread words in the listening vocabulary list.
[0024] In the above method for learning listening vocabulary for children, in step S1, when selecting the vocabulary to be learned from the listening vocabulary list to the vocabulary learning list, the method further includes: according to a preset limited number of unlearned vocabulary, limiting the number of unlearned vocabulary extracted from the listening vocabulary list with the state parameter of unlearned to within the limited number of unlearned vocabulary. The limited number of unlearned vocabulary is set to prevent too many unlearned vocabulary from discouraging learning enthusiasm.
[0025] In the above method for learning listening vocabulary for children, in step S2, special symbols corresponding to the state parameters of being able to speak, understanding, forgetting and not learning are pre-set, and the state parameters corresponding to each vocabulary to be learned are recorded by different special symbols. Using special symbols to record the learning situation can make it easier for users to record.
[0026] In the above method for children's listening vocabulary learning, in step S4, the operation of recording the word frequency sequence number in the entry includes:
[0027] Compare each recognized word with the built-in dictionary. If the word is found, get the word frequency number corresponding to the word; if the word is not found, enter the word form restoration step. The built-in dictionary consists of two parts, one part comes from the word frequency table of the foreign corpus, and the other part comes from China's daily survival English words. The former comes with the word frequency number, and the latter's word frequency number is all set to 0.
[0028] In the above method for children's listening vocabulary learning, in step S4, the operation of the word form restoration step includes:
[0029] S401, traversing the parts of speech of the word, extracting a part of speech from a part of speech list in turn and assigning it to the word, the part of speech list including nouns, verbs, adjectives and adverbs;
[0030] S402, using the word and the part of speech of the word as parameters, performing lemmatization on the word through a lemmatize algorithm to obtain a restored stem word;
[0031] S403, compare the restored stem word with the built-in dictionary, if the word is retrieved, obtain the word frequency number corresponding to the stem word, and replace the original recognized word in the entry with the stem word, if the word cannot be retrieved, return to step S401, after the word parts of speech are traversed in sequence and the word is still not retrieved, the word frequency number of the word is recorded as the default value -1. The lemmatize algorithm is a word form restoration algorithm, and the word form restoration operation can eliminate the inflectional form of the word, extract the stem, and prevent overestimation of the listening vocabulary. In addition, by restoring the word form, the word frequency number can be accurately recorded, which improves the efficiency of vocabulary learning.
[0032] In the above-mentioned method for learning listening vocabulary for young children, in the step S4, the learning date recorded in each entry is the current date, and the review interval is set according to the word frequency sequence number. When the word in the entry is judged to be not a high-frequency word or a low-frequency word according to the word frequency sequence number, the review interval is set to the default value. When the word in the vocabulary is a high-frequency word or a low-frequency word, the review interval is set to n years. High-frequency vocabulary refers to words with a word frequency sequence number less than 1000. The frequency of occurrence of this word is very high and does not require deliberate review. Low-frequency vocabulary refers to words with a word frequency sequence number greater than 10000. This word is not very helpful for subsequent reading enlightenment. Therefore, for the words in these two situations, the review interval is set to n years, and n can be set to 100, which is equivalent to only recording the learning status when learning, and not actively reviewing. Set the review interval to the default value, which can be set to 1 day, and other numerical settings can also be made according to user needs.
[0033] In the above method for children's listening vocabulary learning, in step S5, the words of each entry are compared with the words in the listening vocabulary table. When the comparison is successful, the operation of modifying the state parameter and learning date corresponding to the word in the listening vocabulary table includes:
[0034] When the status parameter of a certain word in today's listening vocabulary list is understood but the status parameter of the same word in the listening vocabulary list is spoken, the status parameter of the same word in the listening vocabulary list is still recorded as spoken; when the status parameter of a certain word in today's listening vocabulary list is not learned, the status parameter of the same word in the listening vocabulary list is not changed; in other cases, the status parameter of the corresponding word in the listening vocabulary list is modified according to the status parameter in today's listening vocabulary list;
[0035] The learning dates of the corresponding entries in the listening vocabulary list have been changed to the current date.
[0036] In the above method for children's listening vocabulary learning, in step S5, the words of each entry are compared with the words in the listening vocabulary table. When the comparison is successful, the operation of modifying the review interval corresponding to the word in the listening vocabulary table includes:
[0037] When the status parameter of a certain entry in today's vocabulary learning table is "speakable" or "understood", the review interval of the entry in the listening vocabulary list is doubled; when the status parameter of a certain entry in today's vocabulary learning table is "forgotten" but the status parameter of the entry in the listening vocabulary list is "speakable" or "understood", the review interval of the entry in the listening vocabulary list is halved and rounded up; when the status parameter of a certain entry in today's vocabulary learning table is "forgotten" but the status parameter of the entry in the listening vocabulary list is "forgotten" or "not learned", the review interval of the entry in the listening vocabulary list is set to 1.
[0038] In the above method for children's listening vocabulary learning, in step S4, the number of learning times is also recorded in each entry, and the number of learning times is set according to the state parameter. When the state parameter is unlearned, the number of learning times is set to 0, and when the state parameter is forgotten, understood or can speak, the number of learning times is set to 1;
[0039] In step S5, the words of each entry are compared with the words in the listening vocabulary list. When the comparison is successful, the learning times of the entry in today's listening vocabulary list and the learning times of the corresponding entry in the listening vocabulary list are added, and the learning times of the corresponding entry in the listening vocabulary list are assigned; if the learning times of the entry with the status parameter "forgotten" exceeds the set value, the entry in the listening vocabulary list is deleted.
[0040] Compared with the prior art, the method for children's listening vocabulary learning can accurately count the children's listening vocabulary, so that parents can accurately grasp the children's English level, and can also help ordinary families make regular plans for children's vocabulary learning, helping children improve their listening vocabulary learning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0041] Figure 1It is a control flow chart of the present invention. DETAILED DESCRIPTION
[0042] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0043] Embodiment 1:
[0044] like Figure 1 As shown, when using the method for children's listening vocabulary learning to teach children's vocabulary, first print the vocabulary to be learned;
[0045] The specific operation is: when teaching for the first time using this method, the built-in listening vocabulary list will be blank, that is, there is no entry record. First, add the vocabulary to be learned to the vocabulary learning table through the mobile phone or computer or directly print the blank vocabulary learning table, and add the vocabulary to be learned to the blank vocabulary learning table by handwriting. The vocabulary to be learned includes words and notes. Notes are not necessary and can be added or not according to the situation. The vocabulary learning table uses a fixed template format, such as setting a large square with two lines at the bottom around the page as a template format to improve the accuracy of subsequent text detection and recognition. You can also add a small square box □ in front of every other line to set a corresponding word and record the learning status in the small square box □. The small square box □ is set as needed but is not necessary. When this method is not used for teaching for the first time, the built-in listening vocabulary table will have entries recorded. Then, the entries in the listening vocabulary table whose learning date plus the date after the review interval is earlier than or equal to the current date are extracted into the vocabulary learning table. By re-arranging, the words and notes with the status parameter of the entry not learned are arranged at the front of the vocabulary learning table and highlighted, such as bolding. If there are notes in the entry, they are added, and if there are no notes, they are not added. Then, a small square □ is added in front of each word. After all the entries to be printed are placed, small squares □ are added on the remaining blank lines every other line for handwriting to add new vocabulary. After these are completed, the vocabulary learning table is printed. In order to prevent too many words from discouraging learning enthusiasm, the number of entries with the status parameter of not learned extracted from the listening vocabulary table is limited to the limited number of unlearned vocabulary. The limited number of unlearned vocabulary can be set to 10, and the total number of vocabulary to be learned is limited to 60.
[0046] Next, record the status parameters;
[0047] The specific operation is: teach the children through the printed vocabulary learning table, and record the state parameters of each vocabulary to be learned according to the learning situation. The state parameters include being able to speak, understand, forget and not learned. These state parameters can be pre-set with corresponding special symbols. For example, the prefix □+☆ indicates that the word is an active vocabulary, that is, it can be understood and spoken actively, and the special symbol is corresponded to the speaking state parameter; the prefix □+√ indicates that the word is a listening vocabulary, that is, it can be understood, and the special symbol is corresponded to the understanding state parameter; the prefix □+× indicates that the word has not been learned or forgotten, and the special symbol is corresponded to the forgotten state parameter; the prefix simply a small square □ indicates that the word has not been learned today, and the special symbol is corresponded to the unlearned state parameter.
[0048] Next, the learned vocabulary learning table is imaged and image recognition is performed;
[0049] The specific operation of image recognition is: first use the connected text proposal network (CTPN) algorithm for text detection, and then use the long short-term memory network (LSTM) algorithm for text recognition, so as to obtain the words and annotations of each vocabulary to be learned; use the convolutional neural network algorithm to recognize the special symbols corresponding to each vocabulary to be learned, and obtain the state parameters corresponding to each vocabulary to be learned. If the recognized special symbol is a state parameter of being able to speak, the state parameter corresponding to the word is recorded as being able to speak; if the recognized special symbol is a state parameter of being understood, the state parameter corresponding to the word is recorded as being understood; if the recognized special symbol is a state parameter of being forgotten, the state parameter corresponding to the word is recorded as being forgotten; if the recognized special symbol is a state parameter of being unlearned, the state parameter corresponding to the word is recorded as being unlearned.
[0050] Next, create entries based on the words, annotations and status parameters identified in the previous step, and record the table composed of all entries as today's listening vocabulary;
[0051] The specific operation is as follows: create an entry for each recognized word, the annotation corresponding to the word, and the state parameters and record them in today's listening vocabulary. In each entry, the word frequency number, learning date, review interval, and learning times are also recorded. Among them, the learning date is recorded as the current date, the review interval is recorded as 1 day, the learning times are recorded as 0 to 1 times, when the state parameter is not learned, it is recorded as 0 times, and when the other state parameters are, it is recorded as 1 time. The word frequency number is obtained by looking up the built-in dictionary, that is, when a word is recognized, the word is compared with the built-in dictionary. If the word is retrieved, the word frequency number corresponding to the word is obtained; if the word cannot be retrieved, the word form restoration step is entered. First, The word's parts of speech are traversed, and one part of speech is extracted from the part of speech list in turn and assigned to the word. The part of speech list includes nouns, verbs, adjectives and adverbs; the word and the word's part of speech are used as parameters, and the word is lemmatized through the lemmatize algorithm to obtain the restored stem word; finally, the restored stem word is compared with the built-in dictionary. If the word is retrieved, the word frequency number corresponding to the stem word is obtained, and the word in the entry is replaced with the restored stem word; if the word is not retrieved, the operation steps of traversing the word's parts of speech are returned. If the noun was selected for lemmatization last time, the verb is selected for lemmatization this time. If the word is not found in the built-in dictionary, the word frequency number will be recorded as the default value -1. The word with a frequency number of -1 will be displayed so that the user can manually correct it when it is a spelling error. The corrected word will be compared with the built-in dictionary again after word form restoration. If the frequency number is still -1 after processing, the word will be added to the end of the built-in dictionary and the corresponding frequency number will be recorded. After the frequency number is confirmed, each entry is judged whether it belongs to high-frequency vocabulary or low-frequency vocabulary according to the frequency number. If it belongs to high-frequency vocabulary or low-frequency vocabulary, the review interval will be changed from 1 day to 100 years or other values.
[0052] Next, compare today's listening vocabulary list obtained after the above processing with the listening vocabulary list, and summarize the entries into the listening vocabulary list;
[0053] The specific operation is as follows: traverse the entries in today's listening vocabulary list, extract an entry each time, search for the word of the entry in the listening vocabulary list, if the word of the current entry is not retrieved in the listening vocabulary list, add the entry to the listening vocabulary list, and then extract another entry from today's listening vocabulary list; if the word of the current entry is retrieved in the listening vocabulary list, modify the entry corresponding to the word in the listening vocabulary list, including modifying the learning date to the current date, adding the number of learning times recorded in today's listening vocabulary list to the number of learning times recorded in the listening vocabulary list, and then assigning a value to the number of learning times of the corresponding entry in the listening vocabulary list, and modifying the review interval according to Table 1. For example, when the status parameter of an entry in today's listening vocabulary list is "can speak" or "understand", regardless of whether the status parameter of the corresponding entry in the listening vocabulary list is "can speak", "understand", or "can hear", the review interval is modified according to Table 1. If the status parameter of an entry in today's listening vocabulary list is forgotten, but the status parameter of the entry in the listening vocabulary list is spoken or understood, the review interval of the entry in the listening vocabulary list will be halved and then rounded up. If the status parameter is 4 days, it will be changed to 2 days. If the status parameter of an entry in today's listening vocabulary list is forgotten, but the status parameter of the entry in the listening vocabulary list is forgotten or not learned, the review interval of the entry in the listening vocabulary list will be set to 1. If the status parameter of an entry in today's listening vocabulary list is not learned, no matter the status parameter of the entry in the listening vocabulary list is spoken, understood, forgotten or not learned, the review interval of the entry in the listening vocabulary list will remain unchanged, that is, if the original review interval is 1 day, it will remain unchanged at 1 day, and if it is 2 days, it will remain unchanged at 2 days.
[0054] Table 1 Review interval modification table
[0055]
[0056] The status parameters of the entries in the listening vocabulary list are modified. For example, as shown in Table 2, when the status parameter of a certain entry in today's listening vocabulary list is "can speak", the status parameter of the entry in the listening vocabulary list is modified to "can speak"; when the status parameter of a certain entry in today's listening vocabulary list is "forgotten", the status parameter of the entry in the listening vocabulary list is changed to "forgotten"; when the status parameter of a certain entry in today's listening vocabulary list is "understood" but the status parameter of the entry in the listening vocabulary list is not "can speak", the status parameter of the entry in the listening vocabulary list is changed to "understood"; when the status parameter of a certain entry in today's listening vocabulary list is "understood" but the status parameter of the entry in the listening vocabulary list is "can speak", the status parameter of the entry in the listening vocabulary list remains unchanged and is still recorded as "can speak".
[0057] Table 2 Status parameter modification table
[0058]
[0059] After continuous learning through this method, the listening vocabulary list will automatically count the number of words that can be spoken, understood, forgotten and not learned. The total number of words that can be spoken and understood is the child's listening vocabulary. Parents can accurately grasp the learning stage of their children through this listening vocabulary.
[0060] After accumulating a certain amount of listening vocabulary, this method can also help parents choose suitable learning materials for their children. Specifically, first obtain a page of learning materials, extract English words from the page, restore the word form of the English word, and compare it with the words that can be understood and spoken in the listening vocabulary list. If there are 0 to 1 new words on a page, it means that the difficulty is too low and the learning efficiency is not high; if there are 1 to 2 new words on a page, then the difficulty is moderate; if there are 3-4 new words on a page, then the difficulty is slightly higher, but it is still acceptable for some children; but if there are 5 or more new words on a page, then the difficulty is too great and the child will resist parent-child reading.
[0061] Embodiment 2:
[0062] The technical solution in this embodiment is substantially the same as the technical solution in the first embodiment, except that when learning the vocabulary to be learned, the vocabulary to be learned in the vocabulary learning table is learned directly through a computer or a mobile phone.
[0063] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
