psychological characteristics of middle school students the analysis of biological experiments and teaching strategiesabstract: mental health education is an important component of quality education is to promote the healthy growth of young people an important way. this from a psychological point of view to analyze the psychological characteristics of students in biological experiments, and for these characteristics of effective teaching strategies proposed by the hope of future teaching practices provide a useful reference work. key words: biological experiments; psychological barriers; psychological characteristics biology is an experimental science, biological experiments to stimulate students interest in learning, and to enlighten the students thinking, cultivate scientific literacy and the innovative spirit can have a positive effect. to understand and grasp the teaching of secondary school students in the experimental characteristics of mental activity, from the psychological characteristics of students in the design experimental teaching, the students understanding of biological experiments and attitudes lead to the correct track, which will study and work of students in the future and lay a sound basis. first, understand the students psychological barrier of biological experiments, the creation of teaching situation, to guide students into the lab with pleasure for the majority of rural secondary school students who have different backgrounds and biological learning experience, biological experiments also have a variety of views and experience. therefore, teachers should pay attention to some of the students of biological experiments is not a correct understanding of, or a bad experience, analysis of the formation of experimental psychological reasons, the students into a new environment, learning, living with a new vision of the time, the use of appropriate way to rectify the students do not correctly understand and psychological barriers, will play a multiplier role in teaching. 1. the contempt of experimental psychology the shortcomings of traditional test functions, students are re-theory of light experiments, light-weight memory and ability. students affected by this, that the biological experiments is not important, do not do can experiment to learn, to test a good bio. these students choose to stay away for biological experiments have often taken the attitude, doing half-hearted experiment does not require action or inaction in strict accordance with the experimental recording and analysis of the phenomenon is often taken to deal with subjective judgments or copied. to have this mentality of students, teachers should always emphasized in the teaching process, first, the biological experiments to cultivate scientific literacy and scientific capacity for future study and work is good; the second is to introduce the test in recent years, university entrance test the theme of the fact that scores increased year by year, as well as in the exam, college entrance examination test questions of the novel, flexible, integrated and strong features, there is no rigorous experimental operation training, but is simply recite from memory, and get good these topics. through such reasoning, the experimental classes allow students to learn from the minds pay attention to it. 2. for fear of the experiment fear of belonging to the psychological barrier of external stimulation on the brain and vegetative nervous system, the result of weakened or eliminated once the external stimulus, which will subsequently play down the psychological and disappeared. therefore, the students just to do biological experiments, the teacher should not introduce new stimuli, and to take some measures to eliminate student fear. first, laboratories ventilation is good, to give the students first enter the lab to create a good environment to change the idea that laboratory toxic, sickening mentality. second, we should arrange some more quiz experiments have allowed the students to experiment and feel the biological experiments in other disciplines can be difficult to get experience and fun to play down the fear. 3. to do the psychological tension experiments students experiment operation is often a result of the psychological tension caused by inexperienced operators, some not seen before, experimental equipment, the students it is very strange, is not used, there are bound tight. sometimes several times not been properly done, the more nervous. this requires teachers to guide the students in the teaching of great importance to pre-prep classes, as well as training in the basic operation of biological experiments. in the training, teachers not to seek quick results, but students should be combined with practical, progressive approach, step by step so that students can repeatedly practice their own experience, practice makes perfect, students in the experiment naturally confident. second, to overcome the psychological characteristics of students in non-performing experiments to develop students to learn good habits and lasting stability in biological experiments experimental research interests 1. to change the experiment as a magic and curious in psychology, a clear purpose and requirement of the experiment speaking of biological experiments on a normal class, many students are often curious, fresh excitement to the experimental lesson. the teacher explained, they are often too busy to see a variety of instruments, medicines, eager hands-on and made the results and see the phenomenon is very happy and satisfied. their attention is not in operation specification, the purpose of this experiment is not very clear, more is according to prescription fill a prescription. whether they are looking for teachers or a demonstration experiment of their own operations, are based on magic, curious mentality to come back. the long-term treatment experiments in such a mood, not only for the experimental operation of the consolidation of knowledge and ability has little effect, but also to enable students to form pairs of experiments erroneous understanding. grasping pre-class preparation is an effective way to solve this problem. the prep students in general the main experiment is to understand the content, procedures and how to operate and so on, and less thought to understand the purpose of the experiment, teachers should enable students to understand the importance of a clear experimental purposes, specifically to understand the purpose of this experiment to test the skills, knowledge, observation ability of various requirements. the pre-class preparation for the depth, we can make one or two questions, ask students to think. 2. to overcome the psychological simply interested in doing experiments to cultivate the attitude of rigorous scientific experiments biological experiments enable students to be difficult to understand from other sources of happiness and interest, but the students are in puberty, their interests often can not durable, easy to transfer. with simple experiments for students interested in ideas, but to pursue some kind of emotional need or stimulus, learning is just buys them on intuition, to learn the hard nature of not prepared for. when the experimental operation requires numerous times, they will feel dull and the transfer of interest; when the experiment when subject to discipline, they will transfer their interest; when criticized by the teachers, or teachers do not like the image of linguistic features, they will transfer their interest. in this regard, we want a way to their initial enthusiasm for the experiment, biological experiment transformed into a lasting interest in stability, to develop their critical attitude towards scientific experiments. first of all, you can introduce students to examples of great scientists. second, you can experiment through research learning activities, there is consciously experimental interest arising from intuition to guide the experimental causal relationship or the experimental nature of the study in order to enable them to make biological experiments not only became interested in power, promote students has also become an important psychological factor in the development of good quality. reposted elsewhere in the paper for free download http:/ again, in the experiment, teachers should be more tolerant and less unnecessary constraints; more encouraging, less blame; more strict, less strict; more guidance and less interference. finally, teachers should strengthen their own self-cultivation, so that clothes clean, beautiful, vivid language friendly, in the laboratory should maintain appropriate emotional state, and demonstration experiments operation should be standardized as far as possible, skilled, smart, clear-cut phenomenon, giving to the united states of enjoyment of the experiment to decisively deal with the accident, but can take it easy, so can the students parents of their teacher and the letter of its road. third, a good grasp of the psychological characteristics of students whose timing, innovative thinking ability of students 1. seize the psychological apply their knowledge to carry out experiments with live links applications are the driving force of innovation and social development, but also student motivation to learn. high school biology textbooks in the experiment is based on training in basic operations and validate the knowledge-based learning, experimental theoretical strong, starting with students have a high enthusiasm and interest in doing more, students will think, apart from such knowledge test the needs of what will be the real-life relationship? if this problem is not a long-term answer, it will enable students to form a biological experiment has nothing to do with the life of the science, and therefore some students will lose interest in biological experiments. context of biological experiments and timely treatment to increase fun, practical experiments will be well positioned to meet the psychological needs of students, and even made an unexpected benefits. such as production cell model in this experimental material in the agar is not easy to obtain, relatively high requirements. in an experiment, i allow students to consider what materials can be used instead of agar, the availability of a better way, so that it is economical and cost-effective? some of the students thought of using gelatin instead of agar, in the production process, gelatin shell to do the cell membrane for chloroplast mung bean, peanut doing the nucleus. as a result, an economical and ornamental value of the cell model will do the work. 2. to stimulate the design of psychological experiments to develop our ability to innovate students do more teaching materials specifically listed in the experimental procedures and experimental use of supplies and experiments will be unable to play because of their own initiative arising from the psychological weary; in addition, the students, through their own experiments and validation experiments, and gradually realize that, experiment is to study the biological structure and function, revealing the essence of life as a means, but also to solve the practical problems of life an important
