In this paper, the role of the classroom blackboard, components, types and requirements to talk about some superficial understanding.

Keywords: classroom blackboard, the role, component, type, required

Teacher lectures on the podium, writing on the blackboard, is essential now, although some other modern teaching techniques have been widely used, however, writing on the blackboard in the classroom teaching still plays an irreplaceable role of the teacher designed classroom writing on the blackboard, is an indispensable teaching an important part of the necessary means to improve teaching quality In order to do a better job of teaching, we should carefully designed writing on the blackboard.

First, the role of the classroom blackboard
(View image has been enhanced memory
Well-designed writing on the blackboard to the teacher talking about the content of the outline clearly on display, visual image to show the essence of teaching materials can be activated students auditory, visual, and promote the exchange of information, students can be taught to teachers in the use of writing on the blackboard out of the summarized points to see clearly, hear understand, remember and accurate so that the students listened and took notes, eyes, ears, hands, brain while mobilizing a variety of senses, co-ordination, both Gangjumuzhang, replicability, but also to enhance understanding of key and difficult to enhance memory, if not pay attention to the blackboard, write without chaos rub, blurred the student does not look pleasing to the eye, they can not see teachers teaching points.

(B to stimulate interest in improving efficiency
Well-designed writing on the blackboard, are symbols, pictures, lines and text on the blackboard of the organic combination, you can appeal to the students, attention, and even beauty, to stimulate interest in learning through writing on the blackboard, students can visualize cognitive Teachers display the contents of the outline on the blackboard, or even suit, learn ways to teach teachers, skills and techniques. Naturally improve teaching efficiency. Notifications wide range of applications, the use of high frequency. Is designed to inform the writing on the blackboard, for example, designed to demonstrate the role of writing on the blackboard. In the first-year students for post notification of the complexity of the writing is more difficult to master, but for general Affairs of the notice, must learn. combined with text content and examples to provide students with this writing on the blackboard, so that they 依葫芦画瓢, a careful student lectures, written notice of the operation can be completed, because such writing on the blackboard, is to learn that with the bridge.

(C reveal the key ideas embodied
Blackboard is an important part of teaching is effective teaching information transmission means good writing on the blackboard, to reflect the logic level of the teaching content and teaching experience of the program, with a role in attracting students to guide the student to use Blackboard to optimize understanding of teaching content key and difficult to master, up to teaching ideas, teacher thinking, thinking of the trilateral students resonance. foundation is particularly poor, slow response of the students, keep up the teaching process, did not understand the relevant terms of the time could be of benefit, for example: in teaching <<Drug>> when writing on the blackboard design is as follows:
Enjoy reading the novel as a class, the dozens of pages of highly condensed summary of the contents of the text, concise floor book, full of the overall structure and main contents of clear, students glance, easy to grasp, on the theme, characters analysis, teachers with the necessary coaching students easy to understand, and left a deep impression.

Second, the components of classroom blackboard
(A pen
Currently, most classroom pen or chalk plaster. Chalk short, easily broken, should try to grasp the root, natural and smooth writing was to write the same time, teachers can use different colors of chalk, create a pleasant learning environment, students in the visual was lively on, generate interest in learning.

(B) writing
The first should be written correctly, including spelling do not write, do non-standard characters, followed suitable to the size, the word is too much effect on the utilization of the blackboard, the word unclear underestimated, font size, students should be able to see the back of the classroom as a standard. In addition to writing neat, regular script as well, the individual running script can be, should illegible fuzzy, leading students to read. Finally, even parallel, structure and clear, uniform font, line spacing parallel. To be clear writing, teachers in teaching basic skills to enhance practice, we must observe the various forms of teaching activities, mutual learning, to master the writing skills of classroom board book.

(Three forms of
Commonly used form of writing on the blackboard: 1, text, including Chinese characters, foreign languages, Arabic numerals, etc., 2, symbols, special symbols, including the various disciplines and usually used symbols, solid line -, dashed line ..., arrow →, size in number> < , triangle △, circle ○, □ boxes, etc., 3, drawings, 4 tables.

(D blackboard layout
Limited board blackboard, blackboard layout should seek to compact, complete and generous.

1, the center plate. Center for the motherboard, not just rub on both sides to stay a little, for auxiliary use, can write with the brush with.

2, two sub-board the whole board into two, left for the motherboard, right as deputy board.

3, the third plate. Left for the board, a large outline of the column, do not rub the curricular, the deputy board, write the appropriate subtitle, pay attention to a summary of major points revisit the second point after a wipe, right to mobility for drawing or supplements, may speak with the brush with.

4, a quarter or a fifth of the board board would be a large lecture outline horizontal row one, two, three, four labels, and then written down by a large vertical outline headings or related points, try to be brief, a lesson a plate, basically does not rub . Also, the writing on the blackboard can be used for the actual situation with the arrangements. "Real" is the writing on the blackboard teaching materials truthful and accurate, clear. "Virtual" is deliberately left vacant when the writing on the blackboard for students to understand the full complement after.

(A composite-type writing on the blackboard
Through text, pictures, tables, symbols such as the integrated use of various types of writing on the blackboard in the form of random removal of a comprehensive education system to pass information for content-rich, comprehensive and strong classroom teaching.

(B-type writing on the blackboard clues
According to materials provided by the clues, together with the arrow, line, and concise text, showing the link between knowledge, or layer into, or cause other changes in order. This method is like a necklace, a material such as a dolphin beads, there is always a clue implicated live.

(Three words-style writing on the blackboard
Best reflect the content of the text through the combination of words, that the order of things, the structure of the process. As argumentative, "first", "Second", "Again", "last", recounting the day "morning", "noon", "afternoon", indicating the position with the "top", "below", "middle "and so on.

(One to be focused, avoid exhaustive
Focus is the classroom blackboard should follow the principle of focus to guide the students to master course content plays a finishing touch [1], which requires teachers to teach intensive reading materials carefully prior to, clarify and focus on teaching the knowledge points and difficult , according to the teaching content to determine the content and writing on the blackboard classroom blackboard steps lay the foundation to improve the quality of teaching the teacher if you can not accurately grasp the key difficulties, not the content of the writing on the blackboard for the meticulous arrangements, and classroom blackboard will be focus on the phenomenon, the effect on will be greatly reduced. Therefore, teachers must address the purpose of teaching, content, and students practical, focused, and difficult, the local design detail was writing on the blackboard, and strive to guide students to understand the text, the purpose of seizing the essentials, students have to understand, remember the clues , can enhance positive thinking, persistence.

(Second, concise summary, avoid complicated long-winded
Blackboard content to seek concise summary of each class is necessary to show the important principles of teaching content, concepts, formulas, rules, conclusions, etc., but also to avoid the complicated long-winded [2] by a brief, general classroom blackboard so that students clearly should firmly grasp the important content. This requires careful preparation before the teacher teach the teacher to carefully study materials, preparation of lesson plans at the same time, their brains thinking, good writing on the blackboard content design, the framework so that students take notes to facilitate a deeper understanding, leaving the impression, for example, in lecture on "documents and records management>> program files how to mix the fifth step, the writing on the blackboard design is as follows:
The text contents of 5, the content of complex hard to remember in the lectures focus on key, to simplify, and physical specimens, students can read, hear that, while rational knowledge and perceptions have been strengthened, eventually to grasp the purpose of teaching.
