Application of PDA in Mobile Teaching

  • 13 Aug 2019
Since the 20th century, the rapid development and wide application of information technology such as mobile communication equipment, multimedia network technology, and pervasive computing have triggered changes in the field of education, resulting in a new teaching method - mobile teaching. Mobile Education and Learning is a combination of Mobile Education and Mobile Learning. It relies on the more mature wireless mobile networks, Internet and multimedia technologies, and uses mobile communication devices (such as wireless support). A portable computer with Internet access, a Android Handheld Industrial Pda with a wireless communication module, a mobile phone, etc.) a teaching system that acquires learning resources, communicates with others, learns, and implements interactive teaching activities.

From the above definitions, we can find that from the perspective of technical characteristics, mobile teaching is a teaching mode that acquires and transmits teaching resources through mobile devices and mobile communication networks, and can communicate easily and flexibly. As a terminal device that is portable, versatile and wirelessly accessible to the network, Handheld Terminal Device is a new teaching trend applied to mobile teaching.
Handheld Terminal Device is an electronic product that integrates electronic notebooks, laptops, and mobile communication devices. It digitizes the information that people usually need and can be widely used and transmitted. The narrowly defined Industrial Handheld Computer is an electronic notebook with a single function, mainly for managing personal information such as contacts, notes and notes, schedules, notes, calculators, recordings and dictionaries.
The handheld computer has wireless Internet access function, which can store and transmit information flexibly. It is easy to operate, compact and easy to carry. It has gradually become a powerful handheld technology teaching tool for people in mobile teaching. It features calendar, address book, task table and memo for project functions for personal information management, as well as e-books, global positioning systems and maps, electronic dictionaries, music storage and playback, encyclopedias, weather and news, calculators, Database, email, web, Microsoft office software series, etc. In addition to these communication tools, the handheld computer and its accompanying software can provide multi-faceted support for students' scientific inquiry activities.
1. Industrial Handheld Terminal
Pocket PCs, as the name suggests, can usually be held in one hand. They are small and lightweight, and can be conveniently placed in a pocket or in a bag for portable use in any situation. And the battery life is strong, usually up to three or four hours.
2. Accessibility aspects
It not only supports the way of regular Ethernet access to the Internet, but also has wireless Internet access, supports 3G network and multiple wireless connection methods. At the same time, the body is equipped with a Bluetooth chip and can transmit data wirelessly.
3. Interaction timeliness
Because the handheld computer can easily connect to the Internet, it can support online real-time online communication. Learners and teachers can communicate through emails, chats, etc., and feedback learning results. And it can use Bluetooth technology to wirelessly transmit data, so that teachers and students can share resources with each other.
4. Teaching auxiliary aspects
Pocket PCs are rich in hardware and software support, can be installed with a variety of teaching software and are compatible with a variety of operating systems, and the operation is simple, users with a certain computer operation basis will not have difficulty in using. Supports multiple formats of media files, and has a built-in or external megapixel camera that enables you to take photos, record movies, and perform network video.
5. Equipment scalability
There is no built-in hard disk in the traditional sense of the handheld computer. This is because of the size and power consumption. The memory capacity of the system is usually 16MB to 32MB of random access memory (RAM) and read only memory (ROM). The use of flash memory cards and micro hard drives can make up for the lack of storage capacity of handheld computers. In addition, the Handheld Terminal Device supports a variety of software installation and use, to meet the needs of all aspects of the user.
6. Cost rationality
With the development of technology, the production cost of manufacturers is reduced, and the price of Handheld Terminal Device is currently in a generally accepted range of users, generally ranging from 2,000 yuan to 3,500 yuan. In addition, the cost of the network is not high, and broadband tariffs are currently in a reasonable price range.
In summary, the application of handheld computers to mobile teaching is feasible. The entry of Handheld Mobile Computer into the field of education is an inevitable trend, and whether they are welcome or not, they are looking for ways to enter the classroom. Therefore, educators must keep up with the development of modern information technology and actively carry out research on mobile teaching in light of actual conditions to ensure the introduction and use of these technologies in educational practice.
