Information technology teaching method

Abstract

The invention discloses an information technology teaching method. The method comprises the steps that a teacher starts a human face recognition function through an APP on a mobile terminal; the mobile terminal collects the human face information of the teacher through a camera, and transmits the human face information to an intelligent integrated terminal to be compared with teacher information in a teacher information library stored in a cloud platform, and if matching is successful, the intelligent integrated terminal controls a cover to lift and controls a touch display screen of an intelligent all-in-one machine to be started, so that the teacher can operate the intelligent all-in-one machine, and the touch display screen of the intelligent all-in-one machine is used as a carrier forteaching writing on a blackboard and for rich media calling and operation; and meanwhile, the intelligent integrated terminal is in communication with the display terminal, the display function of thedisplay terminal is started, and the display terminal synchronously displays the teaching information of the touch display screen. When the teacher needs to carry out move teaching in a classroom, the teacher holds the mobile terminal, the APP of the mobile terminal is operated, and then mobile terminal communicates with the intelligent integrated terminal, so that the display terminal is controlled to display the teaching information.

Description

technical field [0001] The invention relates to an information technology teaching method. Background technique [0002] Chalk writing on the blackboard is one of the most common traditional teaching methods in my country, and it is also an important and convenient auxiliary method for classroom teaching. "Blackboard writing" in traditional teaching refers to "writing on the blackboard when the teacher is lecturing" or "writing on the blackboard by the teacher", but because the main components of the chalk used in traditional chalk blackboard writing are calcium carbonate (limestone) and calcium sulfate ( Gypsum), calcium oxide, and other small amounts of metal and heavy metal elements such as lead, manganese, barium, cadmium, etc., even if the improved dust-free chalk that appeared in the later period is just adding grease or polyalcohol to the original chalk as a sticky substance. Mixture, then add the raw material with bigger specific gravity, make the specific gravity a...

"Blackboard writing" in traditional teaching refers to "writing on the blackboard when the teacher is lecturing" or "writing on the blackboard by the teacher", but because the main components of the chalk used in traditional chalk blackboard writing are calcium carbonate (limestone) and calcium sulfate ( Gypsum), calcium oxide, and other small amounts of metal and heavy metal elements such as lead, manganese, barium, cadmium, etc., even if the improved dust-free chalk that appeared in the later period is just adding oil or polyalcohol to the original chalk as a sticky substance. Mixture, then add raw materials with larger specific gravity, so that the specific gravity and volume of chalk are increased, and it is not easy to fly away, but the effect is not obvious in practical application

During the whole teaching process, a large amount of dust will still be generated, floating in the air for a long time, seriously polluting the indoor air, and affecting the health of teachers and students
