Application Of2D Bar Code Technology In Interactive Textbooks

With the wide spread of smart mobile terminals, mobile phones as well as tabletPCs has become a new generation of college students living and learning importanttool. This phenomenon makes the adaptability of the teaching mode of "paper books+Multimedia Demonstration" is facing a new challenge.. Looking for new and moresuitable to their mobile terminal type of life and learning, give full play to its ofmobile terminal function and the role of the master and the corresponding operatingskills, for in the era of mobile Internet to achieve individualized and enhance theteaching effect is of important significance. In view of the two-dimensional bar code(2D bar code technology has matured and become one of the most popular mobileInternet era interactive technology, this paper based on two-dimensional bar codetechnology, mainly QR code for the most popular, carried out a new interactiveteaching expression way of design and practice.For the contents of the notes, the term, formula, concepts and so on the use ofCode QR of the low and medium version of the application of the method, so that thenotes can express more knowledge. Use Code QR to expand the contents of theexercises, for some exercises using Code QR to load its topic answer content, andother similar exercises link. Use Code QR to color chart link storage. The versionmore than20version of the QR code for off-line programming textbook algorithmsaid and algorithm code running on mobile terminal application design, proposed andimplemented the offline versions of QR code to build the source code based on thecompiled application demonstration, the realization of a certain length algorithm codeintelligent mobile phone display and operation, which makes the algorithm tohighlight display effect and dynamic operation, more intuitive and easier tounderstand and more interactive.In this paper, the main research results are as follows：1） Through the study and analyzing of QR Code encoding mode, make off mid orlower version of QR Code and higher version QR Code to find the differencebetween them, and to find their creative application under different modes.2） Use the character of mid or lower version to solve problem of extending theannotation content in teaching materials. And Use it to extend the content ofteaching materials, and to realize development of interactive exercises 3） The analysis of the Code QR for different versions of the QR, which lays thefoundation for the application of the high version of the Code.4） Due to the higher version QR Code have the character of bearing large volumedata, algorithm source codes are saved by offline. The algorithm source codes canbe operated with the mobile terminal.5） Through combining cellphones program of reading the codes, build theinteractive environment of running algorithm codes on the smart phone, to realizethat algorithm programs run by browser with the smart phone, and that themodified source codes are interactively operated by the students.Based on the two-dimensional bar code type of interactive teaching expressionway in the teaching process of preliminary experiments show that, interactivemechanism of active classroom atmosphere, enhance the students’ interest andenthusiasm in learning, and improve the effect of classroom teaching in a certainextent.
