Query: The possibility of use of QR-codes in teaching physics   In the article discusses the possibility of using of QR-codes in teaching
physics. It is noted that the technology of recognition of QR-codes can be
attributed to elements of mobile information and education environment. On the
basis of summarizing existing research discusses the advantages and
disadvantages of using QR-codes, and the application of codes in the learning
process. Examples of the use of QR-codes in teaching physics (of physical
quests and web quests, of games, quizzes, polls, creating a virtual exhibition,
creating applications to educational facilities, the creation and study of
computer models of physical phenomena and processes, organization Self-Test)
are described. Found that the mobile learning available to pupils (students),
and elements of the mobile information-educational environment (including
technology development and recognition of QR-codes) have sufficient capacity in
teaching physics.
