Compared with traditional experimental instruments, sensors have more advantages such as variety, new technology, strong functions, fast development, and reliable performance. In the past, experimental measurement equipment included ammeters, voltmeters, spring balances, mercury thermometers, etc., but nowadays, current sensors, voltage sensors, force sensors, temperature sensors, etc. can be used to measure physical quantities. Gerststein believes: First of all, it needs to be clear that digitization is not to overthrow the past informatization of enterprises, but to integrate and optimize the past informatization systems of enterprises. The essence of digitization is large-scale information processing, which aims to improve the benefits of the tasks we want to solve, and achieve some of the tasks we want to solve and the benefits that human ability cannot reach. Optimize business by integrating data, improve management and operation levels, and use new technical means to enhance corporate technical capabilities to support companies in adapting to new requirements brought about by digital transformation changes.
Data collectors have been widely used in actual modern production and life. The application of data collectors in middle school physics experiments enables students to get in touch with and familiar with data collectors in advance and adapt to the requirements of the times. Teachers can use digital experimental equipment to lead students to dare to challenge the tradition to the greatest extent. Teachers can use digital experimental equipment to create scenarios that fill students with passion for caring about things around them and promote the development of students' creative thinking.
It is difficult for the human eye to observe the subtle process in space, and it is generally possible to achieve detailed observation with the help of a microscope. It is difficult to capture and record minute processes in time. It is a difficult point in physics experiments. The visualization of instantaneous changes is especially difficult. For example, the relationship between spring oscillator Ft and xt, the relationship between capacitor charging and discharging current it, collision process research, etc., these kinds of experiments can only be described qualitatively in the past, or simulated demonstrations with multimedia software. The experiment process visualization includes the spatial visibility of the experiment process and the time visibility of the experiment process. This is the cognitive basis for students to analyze the physical process, establish physical concepts, and understand the laws of physics. It is the key to learning to deal with physical problems.
Traditional experimental instruments are indeed difficult to solve this problem due to the intermittent nature of human observation and manual recording. The digital experiment collects and records data in real time through the sensor connected to the computer, and realizes the automatic recording of the experimental process data in the minute process in time. It is equivalent to using the sensor and computer to replace the human eye, hand, paper and pen to record the data, realizing data recording The continuity of time, realizing the "visualization" of instant changes. For example, by introducing sensor technology into the teaching of overweight and weightlessness, it is possible to clearly record images of pressure changes over time in a short period of time, reproduce the process of overweight and weightlessness in detail, and facilitate the summary of the characteristics and conditions of the phenomenon of overweight and weightlessness. The requirements of law teaching.
Rather than taking the opportunity to take off, it is more of a complete transformation. At present, for the news industry, which has been greatly impacted by the Internet and new media, a large number of news reports no longer rely on paper, which no longer has the attributes of mainstream media, and paper teaching assistants are also facing the same problems. As far as teaching assistants are concerned, it does not need to be studied repeatedly, mainly through the examination of each question, to complete the training and consolidation of knowledge. The current online education platform, such as K12, combines the characteristics of the Internet and teaching assistants, through online interactive learning, question and answer, and testing, to give full play to the main functions of teaching assistants in an efficient, convenient and personalized way.
In summary, on the “Internet+” trend, paper-based teaching aids should first be integrated through digital processing of content to form a massive multimedia digital resource library, and form online classrooms, cloud question banks, mobile classroom APPs and other product forms with the help of mobile Internet. Provide students with personalized teaching services, and create an innovative education service platform through private customization. With exploration and development, big data is gradually accumulated online, and big data is used to derive the value of the education industry chain, creating diversified products and services, and realizing the complete transformation of paper-based teaching aids.
