This paper analyzes the difficulties faced by rural primary schools in China at this stage: the number of students in school is decreasing year by year, and the scale of running schools is shrinking day by day; The quality of teachers is not high; Poor school conditions
Wait a minute. Put forward: adjust the layout of rural primary schools; Strengthen the construction of village-level primary school teachers; Improve the running conditions of village-level primary schools with government investment as the mainstay. In order to improve school efficiency.
Only by benefiting from the quality of teaching can village-level primary schools get out of the current predicament.
Keywords: rural primary schools; Scale of running a school; Teachers' quality; Conditions for running a school *
The focus of education in China is on rural areas, and the focus of rural education should be on village-level primary schools [1]. The number of village-level primary school teachers, students and schools accounts for a very high proportion in the country.
More than half. With the development of society and economic growth, the overall appearance of village-level primary schools has changed greatly, and the qualified rate of village-level primary school teachers has been greatly improved.
High, the enrollment rate of rural children has basically reached 100%. But these can't hide that due to the long-term neglect of village-level primary school construction, village-level primary schools are in hardware and
The serious backwardness of software has become the weakest link in basic education. Especially in the current rural economic restructuring, the acceleration of small town construction, rural labor force
Under the background of power transfer, the development of village-level primary schools is more difficult and in trouble. This paper attempts to start with this problem, analyze its present situation and reasons, and put forward corresponding countermeasures.
First, the difficulties faced by village-level primary schools and their causes
(1) The number of students in village-level primary schools is decreasing year by year, and the scale of running schools is shrinking.
The unreasonable layout of village-level primary schools and the declining birth rate in rural areas have, to a certain extent, caused the number of primary school students in each village to decrease year by year and the scale of running schools to shrink.
However, this phenomenon is mainly because more and more parents choose to let their children get rid of the backward village-level primary education from an early age. "Can't let children lose in.
The concept of "starting line" is increasingly affecting rural parents. Parents want their children to get a good education from childhood and cultivate good study habits for the future.
In order to adapt to the increasingly fierce social competition, we should lay a good foundation for our study and life. However, these are not provided by backward rural primary education. So, for the sake of the children's future,
Parents send their children to urban schools, township central primary schools with better teaching quality, and even accompany them in towns. Every autumn, when new students enter school, some small villages
On the road, there will be farmers carrying bags into the city to accompany their children to study. They gave up their land and rented one or two bungalows near the city at a very low price.
On my way to school, I began to work hard with my children. [2] On the other hand, more and more parents who go out to work choose to let their children borrow books in the inflow place. Because of the massive inflow
The local government began to relax the admission policy for the children of migrant workers, and began to accept these children into local public schools without paying extra sponsorship fees and borrowing fees, just like local schools.
Students can enjoy high-quality educational resources equally. Moreover, parents can take care of their children's study and life at any time and eliminate worries. Under the influence of this environment.
At present, the number of students in village primary schools is naturally decreasing year by year and the scale is shrinking day by day.
In the county where the author is located, on the one hand, it is because the government stipulates that fifth and sixth grade students enter the township central primary school; On the other hand, due to the above reasons, the number of students is decreasing year by year.
Insufficient students. Nearly 70% of rural primary schools have to adopt double-person teaching, which not only increases the teaching difficulty of teachers, but also makes the teaching quality worse. Students learn poorly and their learning effect is poor.
Unsatisfactory results lead more students and parents to be more disappointed with school teaching: fewer students enter school and more students transfer to other schools. There is no doubt that the decrease of primary school students at village level,
The shrinking scale of running a school has objectively caused a waste of educational resources.
(B) The overall quality of village-level primary school teachers is not high.
At present, the composition of teachers in small villages is generally "old+substitute", and most of them are old rural teachers who are "teachers who pick up books and farmers who put down textbooks"
A substitute teacher. In some small villages in Sichuan, almost all teachers are over 50 years old, and most of them are "abandoned" by township schools because of their age and qualifications.
Well, we have to go to the village to play the residual heat. Excellent young rural teachers are transferred to urban schools with better economic conditions and geographical location, or go out to work to find another way out.
1. Teachers' professional level is not high, and their education and teaching concepts are backward. On the one hand, among the rural primary school teachers, a considerable number were normal school teachers and high school teachers during the Cultural Revolution.
Technical secondary school graduates have not really reached the corresponding professional level of practical culture, nor have they received systematic professional training. Their knowledge level is limited, the speed of absorbing knowledge is slow, the channels are narrow, they can't keep up with the changes of primary school textbooks and the requirements of the times, and they can't be competent for teaching tasks well. On the other hand, because rural information is relatively closed, communication with the outside world is not smooth.
Not much, which leads to the lag of rural primary school teachers' educational concept and weak educational and teaching ability. The updating of teachers' knowledge and skills can't keep pace with the times, and the updating of modern social knowledge.
Too fast, and the training of teachers is far behind the pace of the times, and new knowledge such as computers and the Internet can't give students an easy explanation (no wonder rural children are knowledgeable)
Much worse than the city people). What about teaching skills? Computer and physical projection teaching are used in cities. I, a teacher who won the first prize at the county level, have never seen these things. "[3]
Therefore, most rural primary school teachers still use the traditional method of "a piece of chalk+a mouth+a book" to complete their teaching, while students' "learning methods" are still "listening, writing, reading,
Five-stage recitation. This primitive and backward teaching method can not only meet the needs of contemporary teaching, but also increase the burden on teachers and students and consume a lot of their time.
And energy, but the teaching effect is half the effort.
2. Teachers have a heavy workload, but their sense of responsibility is not strong. Village primary schools are generally small in scale and poor in conditions, and the number of teachers in a school is small. But in order for students
With the all-round development of morality, intelligence and physique, many teachers have to engage in multi-disciplinary teaching, even double-class teaching. At the same time, in the context of the "migrant workers", rural parents are
Life forces them to go out to work, which makes the lack of family education in rural areas serious. Children are mostly taken care of by their grandparents, or spoiled or indulged. Put what should be a family,
Parents' educational responsibilities are all pushed to teachers and schools, and teachers are required to give more care and care to these students in their study and life, which undoubtedly increases the burden on teachers.
Bear.
The present situation of rural primary schools requires teachers to have strong teaching ability and sense of responsibility. However, the social status and economic status of rural primary school teachers are generally low, and some teachers are more professional.
Their own quality is low, teaching enthusiasm is not high, and students are irresponsible. On the pretext that rural children have poor foundation and no plasticity; Lack of parental discipline; The reasons for poor school conditions in small villages,
It is natural that children in rural areas have poor grades and lag behind children of the same age in cities and towns. Many teachers are trying to go to better places, leaving more self-pity and imprisonment.
A teacher full of coquettish energy and uneasy about his work. Some old teachers don't make progress, feel that the tide is gone, they can't get fame and fortune, and they have the idea of retiring for a few years.
Village primary schools have poor conditions for running schools.
In the past 20 years, although the conditions for running rural education in China have been greatly improved, they are still far from meeting the demand, and the pressure of insufficient funds for rural education is increasing.
Bigger and bigger; In the information society, the backward conditions for running schools in rural areas once again lag far behind any period in history [4]. However, due to the lack of funds for rural education.
Due to insufficient investment, the conditions for running village-level primary schools are still not optimistic. Not to mention modern teaching equipment, even basic teaching methods are difficult to meet in many villages. very
The funds needed to maintain normal teaching operation are extremely scarce, and there is no money to buy necessary office expenses or basic teaching instruments and books. Many village-level villages
Primary school land is narrow, and there is no space for students' activities; Tables and stools are broken; There are no basic teaching facilities for sports, music, art and other activities. The most serious thing is danger.
The room is particularly concentrated. For example, there are 48 1 schools in Yibin, Sichuan, among which 35 1 schools are village-level primary schools, accounting for 72.97% of the total number of dangerous schools.
The area of first-class dangerous houses accounts for 68.08% of the area of village-level primary schools, which has seriously threatened the safety of teachers and students [5]. The poor running conditions of village-level primary schools have seriously affected and hindered our country.
Develop and improve rural basic education.
Second, the corresponding countermeasures for rural primary schools to get out of the predicament
Village-level primary schools account for half of compulsory education, so we must attach great importance to their current difficulties. Solving these problems is also the only way to achieve fairness and balance in education.
Close. Otherwise, it is equivalent to losing most of the primary school stage and the foundation of the whole basic education, and there is no quality education for all. Therefore, only
Measures have been taken to completely change the current situation of rural children receiving the worst school education, and to strengthen and strengthen the weakest link in the basic education chain-village primary education.
Education can help village-level primary schools get out of the current predicament, lay a solid foundation for the development of rural basic education and promote the development of rural education.
(1) Adjust the layout of rural primary schools to improve the efficiency of running schools.
Through the analysis of the utilization ratio of human resources and material resources in schools of different sizes, experts believe that the appropriate size of rural primary schools is 24 classes per school, which cannot be
There are less than 12 classes per school. In a "mini" primary school with less than 10 students, the average cost of each student far exceeds that of a high school student for one year [6]. At present, China is too scattered.
The layout of village-level primary schools makes the number of schools vary greatly, which objectively causes the waste of educational resources and the quality of education and teaching can not be guaranteed.
In view of this situation, we should rationally adjust the layout of rural primary schools to solve the problem that the number of students in village primary schools is decreasing year by year and the scale of running schools is shrinking. Villages and towns should base themselves on their superiors
According to the relevant regulations, the layout of rural primary schools should be adapted to local conditions: remove some schools with insufficient students, too small scale and poor conditions, and expand the Ministry.
The scale of running a school with good students and good geographical location; And actively establish rural boarding primary schools: students begin to attend central schools and live in schools from the lower grades of primary schools.
Stay. In this way, the limited education funds can be used and invested together, which can not only ensure the key points, raise the standards appropriately, strengthen the construction of software and hardware, but also give full play to the existing role
The function of equipment can also save money, thus accelerating the development of rural primary schools. In the adjustment, the relevant departments should conscientiously do a good job in population calculation, overall planning and integration.
Manage the layout and do a good job in adjusting the layout of rural primary schools. Don't quit school on a large scale because there are few school-age children, which will violate the principle of primary school students entering school nearby. deal with
Improve the relationship between teaching quality and the number of schools, so as to improve the efficiency of running schools.
(B) to strengthen the construction of village-level primary school teachers.
Building a team of village-level primary school teachers with sufficient quantity and excellent quality can make up for the shortcomings of poor school conditions and unreasonable layout in small villages to some extent. that
How to improve the quantity and quality of rural primary school teachers? I think we should start from the following two aspects:
1. Improve the status and treatment of rural teachers and ensure the stability and expansion of small rural teachers. Especially with a large number of old teachers retiring, leaving their posts and the needs of the Ninth Five-Year Plan, the demand for basic education teachers at present and in the future and the corresponding training volume are enormous. Governments at all levels should conscientiously implement the intellectual policy and do their best to improve the village-level small
Understand the working conditions and living conditions of teachers. Because "teachers can only work if they have the required knowledge and skills, personal qualities, career prospects and motivation.
Meet people's expectations of them. "[7] By improving teachers' recruitment, social status and working conditions, we can mobilize the enthusiasm of village-level teachers in many ways and motivate them to contribute.
Basic education in rural areas. Give preferential treatment to village-level primary school teachers who have worked hard in poverty-stricken areas for many years, and encourage some newly graduated normal students with preferential policies.
Young teachers in the region go to teach.
2. Improve the overall quality of rural primary school teachers. On the one hand, in order to solve the problems of inconvenient transportation, relatively closed information and relatively narrow knowledge of rural primary school teachers, the government and teachers
Education authorities should pay attention to the regularity of teacher training and create conditions and opportunities for rural primary school teachers to participate in continuing education. Master modern teaching methods through study and training.
Section, constantly improve the breadth and depth of knowledge, so as to improve the overall quality of teachers. On the other hand, rural primary school teachers should constantly improve their teaching skills and education level.
Sense of responsibility. According to the different characteristics of students and the requirements of quality education, teaching methods are constantly improved. Using heuristic teaching to cultivate rural children's good thinking quality and creativity
Build capacity to meet the demand for talents in modern society. It is necessary to realize that the primary school stage is the basic stage of talent growth, which directly affects the growth of children throughout their lives and improves their understanding of.
Responsibility of rural children's education: due to the limitation of living environment and learning conditions, rural children need teachers' care, encouragement and help more. Give it to every student as much as possible.
Students, especially migrant children, should know the basic situation, pay more attention to their learning completion and changes, talk and communicate with them more, and get to know them in time.
Existing problems and difficulties. Their education should be based on encouragement, so that teachers' encouragement can be the supervision and motivation for children's learning.
(3) With government investment as the main input, improve the conditions for running village-level primary schools.
There are serious problems in the running conditions of village-level primary schools, which makes it urgent to improve the running conditions of village-level primary schools. Improve the educational and material conditions of village primary schools.
Therefore, it is necessary to give priority to government investment, raise education funds through multiple channels, and tilt the policy to rural and weak remote rural primary and secondary schools as much as possible.
Because the improvement of the quality of village-level primary education cannot be separated from large-scale investment, and there are no corresponding educational conditions, teaching instruments, books or even school buildings, the only way to improve the quality is to
An empty word. In order to ensure that the limited education funds are used to improve the running conditions of village-level primary schools, the central and provincial governments can adopt a "spray" method according to the number of students in rural schools.
Irrigation-style rural education financial system can be avoided by directly transferring rural education funds to rural schools with a nine-year system through banks in a fixed, regular and quantitative way.
Avoiding the interception of education funds in multiple intermediate links can also ensure the stability, equality and reliability of rural education funds [4]. Through the renovation of dangerous houses in village primary schools,
School building construction, purchase necessary teaching equipment, books and materials, etc. , significantly improved the school conditions, management level and education and teaching quality of village-run primary schools.

Problems and Countermeasures in the Construction of Rural Primary and Secondary Education Talents Team
First, the problems of rural primary and secondary education talent team
1. understaffed and burdened. According to the primary and secondary school teachers' standards (division
The proportion of students is: primary school 1: 23, junior high school 1: 18, senior high school 1: 13.5), while rural primary and secondary schools.
The ratio of students to teachers is generally around 1: 27 in primary school, 1: 19 in junior high school and 1: 2 1 in senior high school.
In recent years, the increase in the number of junior and senior high school students is at its peak, and primary schools are one after another.
Offering English classes, equipped with distance education equipment, adding sixth grade, and learning while teaching.
The total number of branches did not increase significantly. Due to the serious shortage of teachers, some schools can only
It is good to adopt unconventional methods such as increasing class size and teachers' workload to solve the problem.
Urgent. Teachers in primary and secondary schools have heavy workload, great pressure and poor teaching efficiency.
It is a common problem that it is difficult for some schools to offer all the courses and new courses.
The curriculum reform has not been fully implemented, and the teaching quality has been affected to some extent.
2. The age structure is too large and aging is serious. Take a town as an example, the whole town is 40
In-service middle-aged and elderly teachers account for more than 60% of the total number of teaching staff, of which 50.
Teachers over the age of 30 account for 30% of the total number of teaching staff, and middle-aged and elderly people account for 30%.
It accounts for 50% of all teachers, and most of them are located in remote areas.
Primary schools with poor conditions and the weakest basic education. They usually take several doors,
Even nearly ten courses have heavy workload, long time and low income. Plus dozens
Many years of hard work, mostly from overwork, seriously ill, and a heart to work.
It is difficult to meet the needs of the current era development and education reform.
3. Obsolete concept and lack of innovative consciousness. In rural primary and secondary schools,
Teachers' conservative and enterprising thoughts are widespread, and the tradition is out of date.
Our education and teaching philosophy is still deeply rooted. Especially for most middle-aged and elderly people.
Teachers, while aging, are also mentally aging, that is, "the ship arrives at the dock and the car arrives at the station", Ping
Do not pay attention to business learning, do not actively participate in continuing education and training, new teaching.
Learning methods and cutting-edge information are slow to respond, muddle along, and push the sky.
Thought. Because the traditional learning and research atmosphere is not strong, some young teachers
I went through "one year, two years, three years" at work.
"Three-year variation" with a round flavor of the year, with the passage of time, it came into being.
I have a lazy idea of "not learning art at thirty" and don't pay attention to absorption when following the crowd.
And the practice of new educational concepts and teaching methods, lack of innovation and competitive spirit.
Knowledge, their professional quality and teaching level can not be consolidated and improved, it is difficult to become a talent.
It is often the backbone of education and teaching.
4. The comprehensive quality is not high, and the adaptability to work is poor. First, the teaching ability is relatively low.
Low. In the teaching of rural primary schools, the results of two basic courses are low, and the students are right.
Insufficient mastery of basic knowledge, poor basic skills and lack of good logical thinking.
And the ability to solve problems. This reflects the knowledge of primary school teachers.
The structure is aging, the teaching ability is low, the level of teaching and research reform is poor, and the teaching methods are poor.
The law is backward. Second, there is a shortage of teachers with one specialty and many abilities, and there is a shortage of art teaching talents.
The teaching of music, physical education and beauty courses in some schools is nominal and the conditions are poor.
The phenomenon of "having a schedule and having no teacher in class" is quite common. Face important things
Festive activities, some schools or units do their best, even in an elephant.
An embarrassing situation in which any kind of cultural program can't be handled. Even some schools do not hesitate to substitute classes.
The price specially invited "master" and "frame facade" from other places. Three, audio-visual education, microcomputer, remote
Modern educational means such as educational equipment are not mastered enough, and advanced ideas are difficult to share.
Replacing educational information resources causes serious waste of resources, backward educational means and poor teaching quality.
The benefit is poor.
5. The disciplines and majors don't match. According to a survey of key junior high schools in a town
Judging from the situation, the school has 68 faculty members and 56 full-time teachers, including disciplines.
Only 35 teachers, accounting for 62.5% of the total number of full-time teachers; Incompatible theme
2 1 teacher, accounting for 37.5% of the total number of full-time teachers. As a computer major student,
There are 4 employees, 2 of whom teach English, 1 teach mathematics and 1 teach information technology.
The matching rate between surgery and subject is only 25%. In order to get a degree, one third.
About the teacher's academic training is not right, the subject and specialty are not right, so be a teacher.
A big obstacle to improving teaching level and giving full play to professional expertise.
6. The academic structure is unreasonable. Low level of education, uneven distribution and unreasonable structure.
Reasonable, leading to the phenomenon that full-time teachers cross majors and sections is more common, teaching
The quality of education and teaching cannot be fully guaranteed.
Second, rural primary and secondary education team building measures and countermeasures
1. Tighten the main gate from the source. First of all, we should strengthen the construction of rural primary and secondary school teachers.
Compilation management, in the approved preparation, we should fully consider the distribution of rural primary and secondary schools.
Wide area, scattered students, many teaching points and other characteristics, according to actual needs, set up posts.
The establishment should be reasonably inclined to ensure the basic needs of rural primary and secondary school teachers.
Secondly, we should implement the teacher qualification system according to law and strictly implement the teacher qualification identification.
Conditions, at the same time, the implementation of teacher qualification examination for the society, and never hire academic qualifications.
Those who meet the standards, have low professional quality and do not have teacher qualifications enter the teaching team.
Wu, affecting the overall quality of teachers.
2. Broaden the channels for teachers' import and export. Vigorously promote the open recruitment system for teachers.
Degree, open recruitment of "skilled craftsmen" with teacher qualifications for the society.
Team, gradually eliminate the existing unqualified teachers; For people over 50,
Education, intelligence and energy can not meet the needs of modern education and teaching.
Teachers can retire, vacate their posts, and make themselves highly educated and knowledgeable.
Young comrades with strong professional ability to speed up the internal training of "new generation"
Thank you ",improve the overall working ability of teachers.
3. Improve the quality of existing teachers. Establish and implement "primary and secondary school teachers"
Team quality improvement project ",strengthen the management of teachers' continuing education.
Implement and vigorously carry out new courses, new technologies and new methods as the focus.
A round of teacher training and continuing education. Encourage young and middle-aged teachers to learn from themselves.
Learning, correspondence and other ways to participate in academic qualifications in compensatory education, and tap the internal resources of education.
Advocate school-based training, pay attention to young backbone teachers, and establish "taking the old with the new"
(course), taking young people as teachers, taking the lower as the higher (grade) ".
Type, improve the mechanism of teachers' continuing education and full-time training, and create a harmonious learning atmosphere.
Focusing on and promoting the development of teachers' connotation.
4. Optimize the internal system reform of education. We should adhere to the concept of "people-oriented",
Further deepen the principle of "principal responsibility system, teacher appointment system and structural salary system"
The main content of personnel system reform is to change teachers' identity management into post management.
Turn the teacher unit into a social person, forming a "personnel can enter and leave, and the treatment can be high-energy."
Low, posts can be up and down "incentive competition mechanism, fully mobilize internal education.
Positive factors stimulate teachers' positive sense of responsibility. Make it bigger.
Adjusting the structural layout of primary and secondary schools and resolutely withdrawing fewer schools and merging them are beneficial to schools.
Poor primary and secondary schools and teaching points, maximize the allocation of teacher resources.
Solve the problems of shortage of teachers and waste of resources.
5. Preference policy is better than rural education. Introduce preferential policies to attract more
Excellent educational talents are rooted in rural education.
6. Vigorously adjust the normal education system. According to the current educational reform and development
It is necessary to increase the adjustment of the layout of normal universities and reform all levels.
Education system, professional structure, curriculum, teaching content and
Methods: Improve school conditions, strengthen internal management, and strive to improve teaching quality.
Benefit of running a school. At the same time, schools should help students broaden employment channels and constantly improve themselves.
The influence and popularity of normal education attract more excellent students to accept teachers.
Example education, providing high quality for sustainable development in rural primary and secondary schools.
Teachers promote the all-round development of rural basic education.
With the rapid development of information technology, multimedia technology has spread throughout all walks of life.
Industry. It has also aroused strong repercussions in the education industry. There is no doubt that this modern
The application of cultural teaching means enhances the intuition and interest of biology classroom teaching.
Sex; The classroom capacity has increased; Develop students' creative thinking; Improve academic performance
Learning efficiency; Optimize the quality of classroom teaching; Fully mobilized the students' learning achievements.
Polarity is incomparable to traditional teaching mode in many aspects. however
The inherent limitations of multimedia determine its application in assisting biology teaching in middle schools.
There are inevitably disadvantages in teaching, and improper use will be counterproductive.
How to make multimedia better assist teaching is a difficult problem that has long plagued all walks of life in education.
Human problems need to be summarized through long-term practice. This paper introduces the multimedia assistant.
Advantages and disadvantages of helping middle school biology teaching.
First, the advantages of multimedia-assisted teaching
1. is beneficial to stimulate learning interest and improve teaching effect.
Bruner, a modern American psychologist, said: "The best stimulus for learning is
Interest in the materials learned. Teachers use multimedia technology in classroom teaching.
Create a pleasant, pleasant and pleasant situation so that students can see this person.
If you hear the sound and feel the scene, you can arouse students' interest in learning, so as to raise
Improve the efficiency of classroom teaching.
For example, when introducing factors that affect the ecological balance, all kinds of natural factors are cut off.
Make a video picture and show the earthquake, tsunami and fire by switching pictures.
The impact of natural disasters such as mountain eruption and debris flow on nature has attracted students' attention.
But you can tell at a glance. And human factors affect nature, leading to being in the middle of the food chain.
Break and destroy resources, and collect photos and videos that destroy the environment.
Such as water quality and air pollution caused by the disorderly discharge of "three wastes" in factories; Chop.
Soil erosion and sandstorm caused by logging; Part of life caused by predatory development
The phenomenon of endangered species is made into electronic courseware. These are close to life.
Pictures and beautiful language descriptions greatly enhance the classroom atmosphere and make
Students not only master the reasons for the destruction of ecological balance, but also experience it personally.
Understand the importance of protecting the environment and creating a good ecology to human beings. therefore
Stimulate students' love and environmental awareness. This also enhances its biological knowledge.
Interested.
2. It is beneficial to concretize and visualize abstract biological problems.
Many knowledge points in high school biology textbooks are abstract, such as quality.
Cell wall separation and repair, photosynthesis, meiosis, DNA replication.
Control, gene control the synthesis process of protein; Three basic principles of gene inheritance.
Explanation of the nature of law, etc. Students often have some difficulties in understanding. but
If multimedia technology is used, it will be expressed in the form of animation and dynamic process.
Give students, make the abstract knowledge content concrete, vivid and concise, and then
It can greatly enhance students' perceptual knowledge and promote students' understanding and memory.
It is helpful for students to master the main points of knowledge from shallow to deep and from phenomenon to essence.
Break through the difficulties.
3. It is beneficial to simulate the microscopic world into an intuitive macroscopic world.
Biology, as a natural subject, has been deeply studied in the microscopic field.
It reveals all kinds of mysteries of life, and students must be able to understand the essence of life.
Modern information technology.
