The Research On The Teacher’s Language In An Efficient Biology Class

With the deepening of quality education and the implementation of the new curriculum standard, result and efficiency are both important to teaching. How to prepare an efficient biology class has become a key problem for schools and teachers.Teacher’s language is the professional language in a biology class, is the information carrier for the communication and transmission of message in class, plays a key role in promoting the effectiveness in class. So the object of research in this paper is the teacher’s language in an efficient biology class.Through the survey of the research status at home and abroad, the author find out the problems in the research of the teacher’s language and determine the idea and method on the research topic.The author carry out the research through questionnaire survey, case comparison and experiment. First, the author do some questionnaire survey among teachers and students so that to sum up some language types and features which is easy to accept and can promote the initiative and activeness of the students. Through the survey the author has an deeper understanding of the current situation in the acknowledge and use of the teacher’s professional language. Then the author do comparison of some teaching case among the green hands teachers, mature teachers and professional teachers. And find out the advantages and disadvantages in the teacher’s language among teachers in different stages. At last, the author put forward some advice in optimizing the teacher’s language in an efficient biology class as follows: first, teachers should change their ideas, realize the importance of the teacher’s language in promoting the teaching efficiency. And from some points to optimize their language: 1. enjoyment. In order to attract students to stimulate students ’enthusiasm for learning while teachers’ language needs have fun, in addition to the interesting language teachers also can actually enhance the teaching language by contacting interesting life. 2. scientificity. As animportant component of natural biological disciplines, its own scientific requirements teachers must be rigorous, vague language teachers will lead students to knowledge of the mistake. There are many professional courses in biological terminology, students master the course content easily confused, so teachers in the use of these specialized terminology should be more cautious. 3. conciseness. Simplicity of language teachers require teachers of language concise language teachers to enhance simplicity through constant practice can be corrected, the problem may be complex to summarize contrast.4.rhythmicity. Rhythmic language teacher performance in both the speed and intensity.speed performance in an appropriate and timely pause repeat the language of dynamics refers to the strength of the language of ups and downs. In addition, teachers need to utilize a variety of specific teaching languages: 1. Import language. Import time control in 3-5 minutes, the starting point must be related to the main classroom learning content,and can effectively stimulate students’ interest in learning the language 2. Question language. Design issues need enlightening, but also taking into account the different levels of all students, from easy to difficult layers of depth, according to needs, design a series of logically interlocking problems strings. 3. Evaluation of language. Specifically evaluate the specific behavior for students, usually the first affirm its advantages and then points out the shortcomings. And students adjust to different personality characteristics evaluation methods. 4. The introductory phrase. The introductory phrase is designed for students to different learning levels. According to a recent development principles zone, set for students to learn both higher than their current levels, it can achieve through hard work and self-realization introductory phrase breakthrough. 5.induction speech. Induction should focus on the links between chapters, but also through summarized to effectively distinguish Relevant Concepts.At last, in order to check the effect of the suggestion, the author carry out a teaching experiment. Through the experiment the author confirm the value of the idea in this paper.Through the above study, improve the teachers’ language expression in biology class, not only can improve students’ learning interest, and at the same time also can enhance the effectiveness of teaching.
