Description
One, affiliated technical field
The present invention relates to a kind of electronic teacher pointer, belong to the teacher's pointer technical field of infotech.
Two, background technology
Along with the progress of science and technology, multimedia has become the focus of current teaching field.
Multimedia teaching is a kind of modern teaching means, and it is to utilize multiple medium such as literal, material object, image, sound to transmit information to the student.Compare with common teaching, following advantage is arranged: one, picture and text acoustic image and luxuriant, the mood of multi-angle mobilizing students, emotion, notice and interest; Two, directly perceived, can break through the restriction of vision, the object of observation with multi-angle, and can give prominence to main points, help the understanding of notion and the grasp of method; Three, dynamic reflection notion and process can break through difficult point effectively; Four, stronger interactivity, the student has more participation, and study more initiatively and by creating the environment of self-examination, helps the student and forms new cognitive structure; Five, realized expansion by multimedia, and, cultivated student's exploration, creativity by reproduction and simulation to real situation to common experiment; Six, the repeatability of teaching process helps breaking through difficult point and overcomes and forgets; Seven, specific aim makes the teaching at the different levels student become possibility; Eight, large information capacity, high capacity have been saved room and time, have improved efficiency of teaching; Nine, make some abstract notions hard to understand become concrete observable picture, figure, promptly change abstract for concrete.
This multimedia teaching has the unexistent interest of Traditional teaching means, intuitive, can give full play to teachers and students' enthusiasm, initiative and creativeness, break through the heavy difficult point of teaching, thereby can reach teaching purpose easilier, make the student at happiness, acquire knowledge in the environment easily.
But because technical reason, the teacher often needs to keep on the computer next door in utilizing the process of multimedia teaching at present, seeing monitor, and meanwhile operating computer, Yi Bian explain.And the student is seeing giant-screen on one side, by arrow screen on mark the explanation position of judging teacher on one side, listen teacher's explanation on one side.Teacher's image is not or not student's the visual field, the sight of Faculty and Students can not cross, teacher's body language can't be put to good use, the soul of Faculty and Students can't be linked up, the teacher has become " aside " of multimedia presentation picture, if attention of student one is not concentrated slightly, also might can not find the position of teacher's explanation.If the teacher explains according to traditional teaching custom before standing in giant-screen, though can address the above problem,, must go to the preceding operating computer of computing machine every now and then owing to need switch display frame every now and then, original multimedia presentation for imparting knowledge to students and providing convenience but brings inconvenience to teaching.
The electronic whiteboard demonstration equipment that grew up in recent years, though can address the above problem, the teacher again need not " hurry back and forth " between computer and giant-screen, just can finish computation with electronic pen on screen, has made things convenient for teaching.But, generally, can't satisfy teaching demand than large space below 85 inches because the present screen of electronic whiteboard is less, and cost an arm and a leg, the plate face is had relatively high expectations, saying the class hour teacher between projector and screen, can't solve and shut out the light and projector's intense light irradiation eye problem.
Three, summary of the invention
The object of the present invention is to provide a kind of can overcoming the above problems, the real experience with students that multimedia teaching and teacher are enriched, the educational aid that In-class language combines---multifunction electronic teacher's pointer, identical on this teacher's pointer external form with common teacher's pointer, have and screen size and people and screen between the length that adapts of distance, the indicative function that had both possessed common teacher's pointer on the function, cooperate with the computer multi-media demonstration equipment, can on giant-screen, directly finish computation again as mouse, also have writing function simultaneously, can on giant-screen computer display interface, punctuate, note, explanation.
