Description
技术领域technical field
本发明实施例涉及智能教学技术领域，尤其涉及一种交互式无线教学方法。The embodiments of the present invention relate to the technical field of intelligent teaching, and in particular, to an interactive wireless teaching method.
背景技术Background technique
多媒体教学是指在教学过程中，根据教学目标和教学对象的特点，通过教学设计，合理选择和运用现代教学媒体，并与传统教学手段有机组合，共同参与教学全过程，以多种媒体信息作用于学生，形成合理的教学过程结构，达到最优化的教学效果。多媒体教学其实古已有之，教师一直在借助文本、声音、图片来进行教学。但是在20世纪80年代开始出现采用多种电子媒体如幻灯、投影、录音、录像等综合运用与课堂教学，这种教学技术又称多媒体组合教学或电化教学。90年代起，随着计算机技术的迅速发展和普及，多媒体计算机已经逐步取代了以往的多种教学媒体的综合使用地位。因此，现在我们通常所说的多媒体教学是特指运用多媒体计算机并借助于预先制作的多媒体教学软件来开展的教学活动过程。但是现有的多媒体教学系统往往是老师主讲，而学生被动的参与教学活动，互动性比较差，一旦学生在学习过程中存在什么问题，很难及时反馈给老师，导致教学质量差。Multimedia teaching means that in the teaching process, according to the characteristics of teaching objectives and teaching objects, through teaching design, rational selection and use of modern teaching media, and organic combination with traditional teaching methods, to jointly participate in the whole process of teaching, with the role of a variety of media information. For students, form a reasonable teaching process structure to achieve the optimal teaching effect. In fact, multimedia teaching has existed since ancient times, and teachers have been teaching with the help of text, sound, and pictures. However, in the 1980s, a variety of electronic media, such as slides, projections, audio recordings, and video recordings, were used for comprehensive use and classroom teaching. This teaching technology is also called multimedia combined teaching or electronic teaching. Since the 1990s, with the rapid development and popularization of computer technology, multimedia computers have gradually replaced the comprehensive use of various teaching media in the past. Therefore, what we usually call multimedia teaching now refers to the process of teaching activities carried out by using multimedia computers and with the help of pre-made multimedia teaching software. However, in the existing multimedia teaching system, teachers often give lectures, while students passively participate in teaching activities, and the interaction is relatively poor. Once students have any problems in the learning process, it is difficult to give feedback to teachers in time, resulting in poor teaching quality.
但是，伴随着智能硬件设备如平板电脑的出现，在教学中，教师和学生都配置有一平板电脑，所有的教学课件完全电子化，通过网络，教师的教学课件同步显示到学生的平板电脑上，在教学的过程，学生通过平板电脑与教师进行互动，从而提高了教学质量。但是本发明的发明人在实现本发明的过程中发现，由于过去很长时间教学都依赖于传统的纸质书籍等，即使有了平板电脑等这些智能终端，在教学的过程中也会时不时的用到纸质材料参与教学，获得一些教学结果的反馈。比如需要学生作答印刷在普通纸质上的试题，以检查学习的效果。但是，由于学生是直接在普通纸质试题上做题，教师判卷时，直接在纸质试卷上进行，而且判断对错的过程完全是手动的，另外，判卷的结果也是完全标示在纸质试卷上，没有数字化，当需要对学生的分数进行统计时，必须人工进行统计。因此类似上述两种原因导致了教学系统便捷性较差，而且时间成本较高。However, with the emergence of intelligent hardware devices such as tablet computers, in teaching, both teachers and students are equipped with a tablet computer, and all teaching courseware is completely electronic. During the teaching process, students interact with teachers through tablet computers, thereby improving the quality of teaching. However, in the process of realizing the present invention, the inventor of the present invention found that since teaching has relied on traditional paper books for a long time in the past, even with these smart terminals such as tablet computers, the teaching process will sometimes Participate in teaching using paper materials and get some feedback on teaching results. For example, students are required to answer test questions printed on ordinary paper to check the effect of learning. However, since the students do the questions directly on the ordinary paper test papers, when the teacher judges the paper, they do it directly on the paper test paper, and the process of judging right and wrong is completely manual. There is no digitization on the quality test paper. When it is necessary to count the scores of students, it must be manually counted. Therefore, similar to the above two reasons, the convenience of the teaching system is poor, and the time cost is high.

与上述实施例不同的是，本实施例中，两台识别引擎的识别结果不直接进行比对分析，以确定最终的识别结果，而是作为后续步骤S303深度识别的输入，以生成最终的识别结果。Different from the above embodiment, in this embodiment, the recognition results of the two recognition engines are not directly compared and analyzed to determine the final recognition result, but are used as the input of the depth recognition in the subsequent step S303 to generate the final recognition result. result.
S303、对不同识别引擎产生的数据进行深度识别，生成最终的识别结果，正确反映在所述媒介上的操作。S303. Perform in-depth recognition on data generated by different recognition engines to generate a final recognition result, which correctly reflects the operation on the medium.
本实施例中，与上述实施礼一、二不同的是，至少增加了一个深度识别的步骤，主要考虑了不同的识别引擎基于不同的识别机制，所以不同引擎对于同一点阵反馈数据的识别结果有可能出现差异。比如学员在具有点阵的试卷上写的是数字“1”，有的识别引擎输出的识别结果为数字“1”，有的则是小写的字母“l”。因此，在本实施例中，深度识别的作用正是针对解决类似这种现象。In this embodiment, different from the above-mentioned implementations 1 and 2, at least one step of deep recognition is added, mainly considering that different recognition engines are based on different recognition mechanisms, so the recognition results of different engines for the same lattice feedback data Differences are possible. For example, the student writes the number "1" on the test paper with dot matrix, and the recognition result output by some recognition engines is the number "1", and some is the lowercase letter "l". Therefore, in this embodiment, the role of depth recognition is aimed at solving similar phenomena.
本实施例中，针对上述情形，在深度识别时，可以根据识别结果中相邻两个字符之间的语义关系来判断那个识别结果中的当前字符是正确的。In this embodiment, for the above situation, during deep recognition, it can be determined that the current character in the recognition result is correct according to the semantic relationship between two adjacent characters in the recognition result.
比如学员在教学课件上实际写下的是“213”，一识别引擎的识别结果是21(小写字母l)3，另外一识别引擎的结果是21(数字1)3，通过深度识别判断与“1”相邻的前后数字都是数字(2和3)，因此，位于数字2和数字3之间的“1”同样应该是数字“1”，而不是小写字母“l”。For example, what a student actually wrote in the teaching courseware is "213", the recognition result of one recognition engine is 21 (lowercase letter 1)3, and the result of another recognition engine is 21 (number 1)3. The adjacent numbers before and after 1" are all numbers (2 and 3), so the "1" between the numbers 2 and 3 should also be the number "1", not the lowercase letter "l".
图4为本发明实施例四交互式无线教学方法的流程示意图；如图4所示，本实施例中的方法可以包括如下步骤：FIG. 4 is a schematic flowchart of an interactive wireless teaching method according to Embodiment 4 of the present invention; as shown in FIG. 4 , the method in this embodiment may include the following steps:
S401、点阵读取设备获取当学生使用点阵读取设备在所述媒介上操作时产生的点阵反馈数据，并将获得的所述点阵反馈数据发送给后台服务器；S401, the dot matrix reading device acquires the dot matrix feedback data generated when the student uses the dot matrix reading device to operate on the medium, and sends the obtained dot matrix feedback data to the background server;
S402、所述后台服务器对所述点阵反馈数据进行识别生成反映在所述媒介上操作的数据，以生成教学数据进行互动教学。S402: The backend server identifies the dot matrix feedback data to generate data reflected on the operation on the medium, so as to generate teaching data for interactive teaching.
S403、对所述点阵反馈数据进行处理生成可在网页浏览器中进行显示的对象。S403. Process the dot matrix feedback data to generate an object that can be displayed in a web browser.
本实施例中，与上述实施例不同的是，增加了通过浏览器同步显示点阵反馈数据对应的的操作，其目的至少是将显示的对象与在所述媒介上的操作进行比对，判断所述后台服务器对所述点阵反馈数据进行识别的准确率。In this embodiment, different from the above-mentioned embodiments, an operation corresponding to the synchronous display of the dot matrix feedback data through the browser is added, the purpose of which is at least to compare the displayed object with the operation on the medium to determine The accuracy rate of identifying the dot matrix feedback data by the backend server.
比如：学员在试卷上写下了“213”，通过点读笔将捕捉学员在写“213”的过程中产生的点阵反馈数据发送给网页浏览器同步显示“213”。将该同步显示结果“213”与步骤S402中的识别结果即反映在所述媒介上操作的数据进行比对，如果完全吻合，则步骤S402中的识别准确率较高或者说符合要求，否则需要对S402中的识别进行调整或者优化。For example, the student writes "213" on the test paper, and the dot matrix feedback data captured by the student in the process of writing "213" is sent to the web browser to display "213" synchronously through the reading pen. The synchronous display result "213" is compared with the identification result in step S402, that is, the data reflected in the operation on the medium. If it is completely consistent, the identification accuracy rate in step S402 is higher or meets the requirements, otherwise it needs to be The identification in S402 is adjusted or optimized.

For those of ordinary skill in the art, it can also be displayed on a terminal or device such as an electronic whiteboard, tablet computer, etc., as long as it can be used to judge whether the background server has any effect on the dot matrix. The accuracy of the feedback data for identification is sufficient.
