The advantages of whiteboard teaching

 Whiteboard in Chemistry Teaching pros and cons of the teaching deemed create professional production machine, LCD whiteboard, one PC, touch TV-One PC, touch one, touch LCD advertising to introduce you: traditional multimedia courseware in chemistry the classroom has been widely used, but in the application process, there are no drawbacks, such as: fully integrated with traditional teaching difficult, the lack of interactivity, lack of flexibility and other content. Interactive whiteboard system has a lot of traditional multimedia system does not have the feature that facilitates flexible and efficient implementation of the teaching process, to facilitate the generation and preservation chemistry class dynamic resources, so as to significantly improve the efficiency of junior high school students of the school. Chemistry itself has a rich and varied teaching resources, pictures, video, and other multimedia information experimental demonstration volume and other characteristics, in the classroom, the teacher always use certain media technology to present to students, teaching content and information transfer even organize teaching activities to enrich students' perception, and enhance the effectiveness of teaching. In recent years, we present the information in teaching chemistry classroom teaching mainstream multimedia courseware. However, there are many traditional multimedia courseware difficult to overcome deficiencies. Classroom teaching schools desperately need a way to set the length of the blackboard and multimedia technology, interactive whiteboard appears just to achieve this goal. "Information technology is a breakthrough in basic education: from School Link to classes in" the conclusion further: Classroom Lectures require special integrated information technology, electronic interactive whiteboard is this solution, it will certainly become the classroom information of first choice, and will soon become the mainstream classroom teaching information technology. I. Introduction ?? interactive whiteboard interactive whiteboard system that contains an interactive whiteboard, computer systems and other basic components of projection equipment, computer hardware and software as the core, large interactive display interface featuring a kind of media mix. Among them, the core components of the hardware system consists of a whiteboard, projector, computer and stylus (also known as whiteboard pen, mouse pen) components. Interactive whiteboard is the main system, it is both inductive pen interface and operation, but also monitors and projectors computer's screen, stylus pen and a computer mouse with a dual function. Nib can be written on the board, while the tip is equivalent to the left mouse button, you can click and double-click the button on the pen mouse button. Content on a computer screen can be projected onto a whiteboard via projector. When the stylus to write on a whiteboard or operations, as well as through the feeder electromagnetic induction between the whiteboard and the computer will transport digital information into a computer and quickly (to the human eye indistinguishable fast speed) through the projector onto a whiteboard presentation out, in order to achieve the basic operation of various types of interactive whiteboard. In addition, the software system is the interactive whiteboard system is extremely important part, in addition to the above basic whiteboard with support operations and functions, generally also equipped with a variety of expansion modules to perform some auxiliary functions. First, the traditional teaching of multimedia courseware existing problems 1. The traditional lack of interactive multimedia courseware, teachers and students is not easy to communicate. Teachers can not teach in front of the screen when the projected content on the big screen, there is no control, return to the console in front of the computer can only operate to turn to the next slide lecture, therefore, either the teachers from time to time on the screen and the main running between the console and ran dispersed the students' attention, either always sitting at the computer console operations, the impact of body language and the teachers play the full exchange with students. Teachers can only be "mouse clickers" students also had "recorder." Teachers are often confused in the above point, students in the following "record" of sleep. 2. Content inflexible large-screen projection systems can only demonstrate the default content, courseware, once the design is complete, when the teacher can not teach flexible for students, the random editing or deletion, when teaching new teaching machine appears Students have a new problem arises, you can not change, can not fully introduce more variety of information, which not only affects the effectiveness of teaching, and teachers using the blackboard the kind of flexibility, feeling full play to the lost, many teachers feel We have become slaves of the machine. The machine in education, rather than their own teaching. 3. Traditional multimedia courseware difficult for a variety of traditional multimedia courseware message text, pictures, video and other emerging sequencing and thoughtful layout and design should be in place in advance, so that a courseware production cycle is very long, time-consuming force, and daily intense teaching is contradictory. Many teachers in order to complete the courseware and not well specializes in teaching materials and arrangements, but worth the candle. Third, the interactive whiteboard systems to improve efficiency in the junior high school chemistry class specific performance 1. The use of the interactive whiteboard system for flexible and efficient implementation of the teaching process using an interactive whiteboard system to be very flexible to implement the teaching process, it is more than normal Whiteboard adds many useful features, and these features are generally multimedia courseware in teaching are not available. (1) local amplification because most of the blackboard, screen, whiteboard are not particularly large, such as more students in the class, a very real problem is to sit behind the students see clearly on the interactive whiteboard can be easily Take the stylus at the desired part of the enlarged circle draw, this part of the contents magnified. A major outstanding characteristics (2) storage function interactive whiteboard system, ie writing on the blackboard content can be stored. Written on a whiteboard drawing any text, graphics or insert any image can be saved to a hard drive or removable storage device available to the next class, or in the other classes in the second half, or shared with other teachers; you can also use electronic format or print it out in print the way for students or for after-school study or as review the information. This will not only improve the efficiency of the classroom, but also to help students after school to achieve an accurate knowledge of recognition. (3) function uses the searchlight searchlight function interactive whiteboard system, can make major and difficult appear very prominent, mainly junior high school biology teaching high school students for grades seven and eight, they have a strong curiosity, but they not very good self-control, easily distracted, so teachers should find ways to make the classroom became lively and interesting, in addition to the design and teachers from teaching charismatic accomplishment to proceed, the classroom or the sudden appearance of some new things it is possible to effectively cause the attention of students, to stimulate their interest, so that their attention can unite in the classroom, promoting junior high school biology class efficiency. (4) editing, annotation feature for already making good courseware, teachers in the whiteboard annotation mode, the original courseware control and annotation, and even marked on the number of video files, expand explain in detail, better guide students to grasp the important information. Using the interactive whiteboard system instantly convenience and flexibility to introduce various types of digital information resources, and flexible multimedia material editing organize, display and control. During video playback, and certainly we need to do some explaining and text annotations to complete the instruction. Before a conventional class preparation, teachers need to use video processing software captured video or adding text processing, which virtually increases the difficulty of teacher preparation. Use the interactive whiteboard system, teachers can freely annotate on the video screen, etc. So, you only need to make a simple shoot video clips with or without treatment can be used directly in the classroom. Interactive Whiteboard decency makes digital resources presents more flexible to address the past in the traditional multimedia system using courseware and teaching materials slide structure is highly curable problems, but also eliminates the need for preparation so that the teacher before class, spend technology time and energy on the problem, you can have more time to study the instructional design to improve efficiency in the classroom. (5) the use of interactive whiteboard system playback playback feature, you can process as many times as the previous playback operation, which in the teaching process is very useful. For the time teachers are teaching in general say again, but some difficult and doubtful enough for some students say again, this can put this process several times playback by students choose whether to study again according to their own learning, not only can reduce the workload of teachers, but also to meet the needs of students at different levels, achieve hierarchical teaching, thereby increasing the efficiency of the classroom. (6) The drawing features interactive whiteboard system has a rich variety of geometric shapes and Instrumentation Diagram biochemistry, experimental design and facilitate student participation in the learning process. For example, in biological experiment teaching, the need to draw on the whiteboard biological laboratory equipment needed, because of simple operation, students are interested to take part. Students get an opportunity to participate in the practice, fully reflects the interaction, new ideas to participate in courses. Media features play is largely determined by the application of teaching strategies, teaching strategies with advanced rich media technology and have more flexibility and effectiveness. 2. The use of interactive whiteboard systems to facilitate the exchange of teachers and emotion, encourage students paying attention in class classroom education we know is one of the sites most abundant occurrence of interaction between people, teachers can make full use of language, gestures, eye contact and other ways to guide the course progresses. The current multimedia classroom teaching, but teachers have to face stiff sitting work desk computer, use the keyboard, mouse, and other non-humane way to teach. Many teachers are not willing to accept that reflect their modes of teaching, teaching effect is greatly reduced. Interactive whiteboard system in the hands of a teacher whiteboard stylus can be fully realized computer mouse control, thereby breaking the teachers in the use of multimedia courseware for teaching only sit in front of the computer using a mouse limits for teachers more play space, make teaching more lively. Students in the teaching field by teachers or watch television, computer, no longer busy taking notes and no time to think, you can concentrate on lectures and thinking, strengthen the exchange of ideas between teachers and students collision, teaching multiplier effect. When the instruction is completed, the computer and whiteboard has been automatically records all the writing on the blackboard content just teachers, teachers can conduct all or part of the storage necessary writing on the blackboard. These files are then published as a teaching resource to the campus network or teacher pages, students can download knowledge of feedback review. In the classroom, teachers and students emotional harmony is the premise of paying attention in class, one can be a powerful guarantee for improving classroom efficiency. 3. Using the interactive whiteboard system facilitates dynamic generation of biological resources and conservation classroom with interactive whiteboard system, after teaching is completed, then the video content writing on the blackboard, speaking teachers, students, etc., using the corresponding software can be the system automatically recorded to form a picture of the classroom teaching process includes a reusable comprehensive document, it can also provide students with again. In particular, there are many biological disciplines to explore the experiments, which requires students to design exploration programs, some students designed the program is a valuable classroom dynamic resources that may directly or indirectly be used for teaching. IV Conclusion interactive whiteboard blackboard and chalk neither abandon the model, again the traditional and modern information technology organically combine to make monotonous blackboard into a rich multimedia world, we will not be able to write, edit and computer Interacting projection screen becomes able to write, to draw, to interface with the computer intelligent real-time interaction, creating a structure of both low and can be easily introduced into digital information resources, both real-time interactive have adequate human interaction excellent digital and information technology teaching environment in which a variety of information technology and biology classroom teaching truly optimized integration. In short, the interactive whiteboard system to promote junior high school chemistry classroom teaching efficiency reflected in all aspects whiteboard system features all use whiteboards teachers can appreciate its convenience and efficiency, because whiteboard exhibit excellent interactivity and vivid, students' interest in chemistry will be more intense, chemical scientific literacy will be greatly enhanced. I believe whiteboard teaching junior high school chemistry there are many other promotion, which are to be our teachers are further discovery and practice.
