Seek the teacher recruitment examination for the unified examination of science in junior high school last year.

Please refer to Furong District 20 1 1 science recruitment examination paper.

(Please correct and update the new curriculum standard+original test questions)

Introduction: Registration profile:

After the announcement of 20 1 1 enrollment in Furong District was issued, the number of applicants exceeded 7,000 in just three days, estimated to be around 7 150, and the actual reference number was 6,253, with the proportion of subjects as high as 1: 100.

Examination time and place:

The examination time is scheduled for April 3rd (Sunday) at 20 1 1 at Mawangdui Middle School10: 30-12:10, which lasts for 100 minutes.

General situation of registration reference:

Because the subjects are unfamiliar and the conditions are harsh, for example, freshmen in some subjects require a bachelor's degree or above. Excluding students from a normal university, candidates from a normal university may look down on primary school education, and the information in other places is not very well informed. There are only a few applicants this year, and there are also those from other provinces. There are even fewer real exams in Hengyang Normal University and Hunan Normal University in this province. They became extremely lucky candidates.

In the middle of this year, the original recruitment plan did not reach the ratio of 1: 5, so the quota was transferred to the post.

Source in use:

On-the-job staff are mostly teachers in the province and private teachers who come back from the coast. The main force is the substitute teachers in the schools in Changsha, such as Yu Ying in Furong District, Tianhua in Shazitang and Fengshushan. There are also many people admitted to other districts in Changsha to join in the fun.

Analysis of science test questions in furong district in recent three years;

Compared with 2009 and 10, the examination content has been greatly improved. In 2009, integration was the three major topics, and others were primary and junior high schools. A brief study on the new curriculum standard of 10. The first big question begins with filling in the blanks, followed by relatively simple filling in the blanks. There are more noun explanations and more questions and answers.

Furong district topic 20 1 1:

I think this paper is divided, and I tend to study physics and choose physics as my major to teach science in primary schools. The idea is the same as the 20 10-day science paper. It is reflected in six multiple-choice questions and a big physics problem with a score of 16. This is also determined by the length of science content in primary schools. The abnormal unification of examination papers in different districts may be due to the accumulation of three years' recruitment experience or the result of reference exchange in different districts. It is also the gospel of the majority of candidates.

For the questions of biology+geography+new curriculum standard+pedagogy psychology, please add to them by your colleagues who took the exam: The first big question is multiple-choice questions.

50 questions, each question 1 point, with a total score of ***50 points. The answer is written on the answer sheet with 2B pencil.

A: Starting with physics, there are about six courses. There are three channels for motion and force, and three channels for electricity.

Motion and force

(1) Find the intermediate instantaneous velocity.

The average speed of SAB section is 3m/s, that of SBC section is 6M/S, and SAB=SBC. What is the instantaneous speed at point B? A: 4.5 m/s

(2) Force analysis: the car and the inclined plane move in a straight line at a uniform speed, and the movement to the left only under the action of two forces must be wrong.

(3) When the upward acceleration of the elevator is 1/3g, ask the elevator pressure. A: 4/3g.

Electricity:

(4) Swing at an angle of 30 degrees and 45 degrees to make it balanced, and find the ratio of electricity Q 1:Q2, and the root number of the answer is three.

(5)F=EBL may not be part of the closed-loop error.

(6) Minimum power consumption: L 1(3V/3W )L2(3V/6W), a resistor of 0- 10 ohm, how to connect it, the circuit power consumption is minimum. L 1(3V/3W) is connected in parallel with the resistor and then in series with L2(3V/6W), and the total power is the minimum. Answer b

B: The next three chemistry classes: more difficult, non-professional background, more difficult to complete.

(7) Judgment of nonpolar molecules:

(8) Iron and iron oxide are dissolved in nitric acid, and the concentration of nitric acid is 250 ML and 2MOL/L, and 1. 12LNO is released.

What is the minimum volume of 1 MOL/L sodium hydroxide to completely precipitate iron ions?

Answer: 450ML.

(9) Thermal stability: lithium nitrate, sodium nitrate, magnesium nitrate and copper nitrate.

A: Lithium nitrate is investigated from the electronegativity difference of positive and negative ions.

(10) has undergone chemical changes, resulting in new substances:

C: Biological problem: About five (1 1) biological impacts on the environment: thousands of miles away, it collapsed in an ant's nest.

(12) What does not belong to birds is bats (mammals).

(13) The order of anatomical flowers is: sepals, petals, stamens and pistils.

(14) curve of photosynthesis and respiration: respiration has been going on.

(15) If paramecium and white blood cells (nucleated) are put together in fresh water, then pair B.

A. they will both die. Paramecium survived and white blood cells died. C. Both of them survived. Paramecium died and white blood cells survived.

Solution: paramecium has no cell wall. But it can expel excess water from the body by contracting vacuoles, so that it will not rupture. White blood cells do not have this function, so they will be exploded.

-D: there are few geography questions:

The universe refers to: space.

"Yu" refers to space and "Zhou" refers to time. The universe is a unity composed of space, time, matter and energy. It is the synthesis of all space and time. Generally speaking, the universe refers to a space-time continuous system in which we exist, including all the matter, energy and events in it. According to the Big Bang model, the universe is about 20 billion years old.

E: evaluation subjects of pedagogy and educational psychology (about 15);

It should be diversified, including teachers, students, school leaders, education management departments, parents and other social members and organizations related to school education.

Human capital theory:

The theory of human capital rose in 1950s and 1960s. Generally speaking, Schultz systematically described the "human capital theory" as the symbol of the birth of human capital theory in his speech at the 1960 annual American economic conference.

Personality:

It refers to the relatively stable personality and psychological characteristics with core significance, which are manifested in people's attitude towards reality and corresponding behavior patterns. It is a personality characteristic with the closest relationship with society, which contains many social and moral meanings.

Personality shows people's attitude towards reality and the world around them, and it is reflected in his behavior. Personality is mainly reflected in the attitude towards oneself, others and things, as well as the words and deeds adopted. Temperament:

Temperament is a typical and stable dynamic feature of psychological activities independent of the purpose and content of human activities.

Temperament is one of the psychological characteristics of human personality, which refers to the stable dynamic characteristics such as strength, speed of change and balance when psychological activities such as cognition, emotion, speech and action occur. It is mainly manifested in the speed and intensity of emotional experience, the implication of performance and the sensitivity or dullness of action, so it has a strong color for all psychological activities of people. It is similar to what people call "temper", "character" and "temperament" in daily life.

The difference between temperament and character:

Temperament is not good or bad, it is innate, innate and unchangeable. Personality is acquired and easy to change. People with a certain temperament are more likely to form a certain personality, which can cover up and change their temperament to some extent. The plasticity of temperament is small, but the plasticity of personality is large.

F: multiple-choice questions in the new curriculum. Attach importance to classroom scientific inquiry

Cooperative learning has studied three problems. Requirements for cooperative grouping: homogeneity within groups and heterogeneity between groups.

G: Regular teaching inspection, teaching materials, lesson preparation and lectures. According to the nature of water, the textbook versions are: People's Education Edition, Education Edition and Zhejiang Education Edition. I chose the education edition.

The last multiple-choice question: lecture content: teaching materials, objectives, learning situations, teaching methods, learning methods, processes and teaching reflections.

The second big question, physics, 16.

An object weighing 5 kg slipped down a 37-degree slope and was pulled by a rope with a friction coefficient of 0.25. Find the acceleration of the object sliding down and the tension of the rope. Force analysis must be carried out when solving.

f = gsin 37-ugcos 37； A = F/M = (GSIN 37-UG COS 37)/M (COS 37 = 0.8, SIN37=0.6) The third big question is the chemical experiment question: the origin of life is 8 points, four small questions, and the content of high school chemistry.

For a long time, there are various explanations about the origin of life. In recent decades, according to the new achievements of modern natural science, people have made a comprehensive study on the origin of life and made great progress. According to scientific calculations, the earth has a history of about 4.6 billion years since its birth. The early earth was very hot, and all the elements on the earth were in a gaseous state. At that time, there would never be life. The initial life evolved step by step from inanimate matter through extremely complicated chemical processes in an extremely long time after the earth's temperature dropped. This speculation has been confirmed by scientific experiments. 1935, American scholar Miller and others designed a set of sealing device (below). They pumped the air out of the device, and then simulated the atmospheric composition on the primitive earth. In the water miller experiment, methane, ammonia, hydrogen, water vapor and other gases were introduced from the device, and the lightning was simulated to perform continuous spark discharge under the primitive earth conditions. Finally, amino acids were detected in the U-tube. Amino acid is the basic unit of protein, so it is of great significance to explore the production of amino acids on earth. These gases may naturally synthesize amino acids, nucleotides and monosaccharides under the action of cosmic rays, ultraviolet rays and lightning. Later, the earth's temperature dropped further, and these small organic molecules flowed through lakes and rivers with the rain, and final gathering was in the primitive ocean. At present, people can't verify this process in the laboratory. However, we can speculate that some multi-molecular systems have evolved for a long time, especially the interaction between protein and nucleic acid, and finally formed primitive life with primitive metabolism and reproduction. Later, from the chemical evolution stage of the origin of life to the biological evolution stage after the emergence of life. Question:

(1) What happens if the original atmosphere of the simulated environment is mixed with oxygen? A: It is easy to explode.

(2) Why use water for cooling: The materials are easily available, which is economical and efficient.

(3) Gas molecules generate amino acids and bases under the action of sunlight and ultraviolet rays, which explains what the problem is.

A: Inorganic small molecules synthesize organic small molecules such as amino acids and bases under the action of sunlight, ultraviolet rays and lightning, and then synthesize organic macromolecules. Life originated from inorganic small molecules.

(4) It takes a long time. A: The origin of life has gone through a long time and originated from small inorganic molecules. The fourth big question: Why do you attach importance to scientific inquiry in a science classroom with a score of 10?

A:

First, children's psychological characteristics: curiosity, desire for exploration and abstract thinking need concrete images to support them.

Second, cooperative learning, cultivating unity and cooperation, communication and expression, and training thinking,

Third, the nature of science curriculum content determines the necessity of scientific inquiry.

Examples: biology and environment, matter and its changes, space and cosmology.

Question 5: 16

The ups and downs of objects in water

Talk about your understanding of the leading role of teachers in the classroom.

A:

Teachers' guidance should pay attention to levels and step by step.

Teachers should be good at mobilizing students' enthusiasm and creating a harmonious competitive atmosphere.

Teachers should inspire more and draw less conclusions, give students full freedom of thinking and respect students.

Teachers should not directly refute students' immature conjectures, but should encourage students to improve their thinking level.

Network reference edition: the fourth big question: 10 What does it mean to pay attention to scientific inquiry in science classroom? First, there are many reasons why teaching should be conducted through scientific inquiry. What we want to emphasize is that. Our students should study in a way similar to that of scientists studying science. 1 can keep children's curiosity. People are naturally curious, but later, I don't know why, when I graduated from primary school, the children's curiosity gradually weakened. It is really important to keep this curiosity through scientific inquiry. I've been looking for photos, but I can't find them. That is, at the airport abroad, two Nobel Prize winners in physics (I don't know their names) are watching. What are they looking at? Looking at the gyro on the ground, the gyro keeps turning on the ground, first in the opposite direction, then in the opposite direction. Two fat physicists have been staring at it, trying to see what's going on with this gyro. In fact, what is the difference between scientists and us ordinary people? The difference is that their curiosity can last a lifetime. The year before last, a French expert came to Nanjing, and the children asked him: If you put candy in water, will the volume change? Scientists can't answer for a moment. However, the next morning, people forgot about it. He was the winner of the Nobel Prize in Physics, but he never forgot it. He didn't eat breakfast, but did the experiment first. He added a cube of sugar to the cup one by one, and found that after putting eight cubes of sugar, he could see that the volume had changed a little. Therefore, it is very important to keep children curious. We can keep children's curiosity longer through scientific inquiry, which I think can be seen from the inquiry activities just now. 2. Children can participate in learning activities that require advanced cognitive ability. I want teachers to understand that teaching knowledge can make people smart, which is specious. If you always tell children all kinds of conclusions, children can gain a lot of knowledge, but wisdom does not necessarily increase at the same time, because human wisdom has a great relationship with human cognitive skills, that is, cognitive methods. A research result of a French university emphasizes that what kind of knowledge is profound understanding, knowing is not understanding, reading from the book is not understanding, and reading from the book is not understanding. It has a complete set of standards about understanding, which is to define whether children really understand knowledge from four dimensions: knowledge, method, purpose and form. What is knowledge, whether it exists alone or is linked with other knowledge in the middle of a network, which is an important symbol to measure the quality of knowledge; The second indicator is the method indicator, that is, knowing how this knowledge came from; The third indicator is the target indicator, which means not only knowing how this knowledge comes from, but also knowing where this knowledge can be applied, also called the target dimension; The fourth indicator will be expressed in various forms, also called formal dimension. When children really understand knowledge, they can express their understanding of knowledge in various ways. Therefore, the main difference between the present science education and the science education in the 1960s lies not only in imparting knowledge, but also in cultivating children's advanced cognitive ability through knowledge education. Dewey said: "Science education plays an irreplaceable role in cultivating people's cognitive ability, because the method of teaching science is exactly the same as that of teaching thinking." Dewey, a great educator, saw the unique value of science education at that time-it can make people smarter. 3. It can cultivate children's positive attitude towards science. There is no need to repeat this point. Just now, the teachers were actively participating in the inquiry activities, unwilling to finish the class, and there was no rest between classes. This positive attitude towards science is enough to achieve it. 4. Children can be trained to reach the stage of formal operation. What is the formal operation stage? This is a symbolic action. Piaget said that children after 1 1 can perform formal operations, that is, A > B and B > C, then A must be greater than C. Children can't do it, but they should be able to do it after junior high school. This requires a foreshadowing, which is a concrete thing between the sensory movement stage and the representation stage. Children don't understand the truth that A > B and B > C, so A must be greater than C, but please come up with three students of different heights. He is taller than him, he is taller than him, he must be taller than him, and the child will understand at once. Therefore, through operating activities, children who have not passed the previous sensory movement stage and representation stage and have not reached the formal operation stage can be provided with concrete experiences, because in inquiry activities, they must operate through specific objects. Therefore, in the middle of operational inquiry activities, children can understand this knowledge well. Many children are not so interested in science when they get to middle school (maybe they just don't pay attention to letting students experience scientific inquiry activities). After the 1990s, many countries started "hands-on" science education projects. In the words of George chabat, winner of the French Nobel Prize in Physics, "I was shocked by the enthusiasm of children to learn science in this way", which is why at the age of 80, after winning the Nobel Prize, he stopped doing his physics research and devoted himself to science education projects in kindergartens and primary schools. At present, many provinces in China are carrying out the "learning by doing" science education project introduced from France. In fact, it first started in America. The French were shocked to see what Americans were doing, so the French were doing it. After doing it in France, Minister Wei Yu visited France and saw such a science education project. She also wants to launch a "learning by doing" science education project. After she retired, she specialized in this and promoted this "learning by doing" project in China. The fifth question: 16 points the ups and downs of objects in the water to talk about your understanding of the leading role of teachers in the classroom. Network reference version:

With the increasing voice of replacing exam-oriented education with quality education, the pace of teaching reform is getting faster and faster. Among them, the most prominent formulation is that classroom teaching should change the "spoon-feeding" mode under the traditional teaching method. Teachers are actors and students are spectators, and teachers are required to mobilize students' enthusiasm, cultivate students' interest in learning and guide students to learn actively. This is undoubtedly an effective way to improve classroom efficiency and even students' learning efficiency, but it is not easy to implement. I want to talk about some thoughts on this. First, teachers should correctly understand "guidance". When it comes to "teacher-oriented, student-centered" or "don't want teachers to be actors", the easiest thing to think of is that teachers should suddenly change from "actors" to "directors", and their duties should change from explaining the contents of books on the podium to directing students to learn and understand. It is true that it is not bad to guide students to learn, but at the same time, teachers need some skills to study how to guide students. In other words, the teacher's "guidance" is not simply to lead students to copy down the knowledge points in the textbook one by one, but to guide students step by step in a planned and purposeful way, and to understand the knowledge with emphasis, so as to achieve the degree of flexible use. We often say that lecturing is an art, in fact, guidance is also an art, or rather, it is a more profound art than lecturing. To put it simply, under such guidance, teachers should not only be "directors" of "actors", but also "actors" who play the role of directors. Second, teachers should pay attention to the problems in the process of guidance. Since "guidance" is an art, to do a good job of guidance, we must first pay attention to certain methods, among which the most basic and feasible method is to design student activities reasonably. To improve students' learning enthusiasm and initiative, it is very important to let students participate in learning activities and make them realize that the classroom is not for teachers alone, but for everyone, and everyone has the right to join it. At the same time, through this activity, students will also experience the fun of learning. This kind of learning activity can be designed by teachers, such as asking students to analyze some problems, asking students to express their opinions on an article, or holding some speech and reading competitions. Students can also design their own, for example, teach themselves to learn, make up some textbook dramas and perform them themselves. It should be noted that every student should have the opportunity to participate in such activities, not just students with good grades. The design activities here are mainly aimed at the classroom, but to arouse students' enthusiasm, you can also use your spare time. We can assign some research tasks to students according to the content of the textbook. For example, when talking about Tang poetry and Song poetry, let students consult the materials of poets and poets, understand their life experiences and creative styles, and better understand the content of poetry. Or let students find out the knowledge about the principle of poetry creation, which can not only expand their knowledge, but also save classroom time. Encourage, affirm and praise students in student activities. This practice is particularly important for stimulating students' enthusiasm. Longing for praise is the most basic psychological need of people. After all, students' ideological understanding is still immature, and many times, mistakes are inevitable. At this time, teachers should not be killed by a stick because of their mistakes, but should pay attention to their bright spots and give affirmation and encouragement. Only in this way can students gradually enhance their confidence, and then improve their enthusiasm for thinking. Secondly, when teachers adopt certain methods to students, they should also change their views on their own identity, have the courage to let go of their dignity and correct their mistakes. "Disciples don't have to be inferior to teachers, and teachers don't have to be superior to disciples." This incisive insight of Han Yu is even more to the point in today's era of extremely developed science and technology. Now students' access to knowledge is no longer limited to books, but to the classroom. Various media have opened the door to the treasure house of students' knowledge. So sometimes students' opinions are not necessarily unreasonable, and it is more likely that students' opinions are better than teachers' conclusions. In this case, teachers must put down their dignity, accept new ideas and good opinions, and make students feel that they really have the power to learn, not just puppets manipulated by teachers and parents. Students should be willing to study for themselves. Third, the requirements of "teacher-oriented and student-centered" for teachers themselves. 1, have love and patience. Cultivating students' interest in learning can never be achieved overnight. In the implementation of the whole teaching plan, there will be many setbacks, and sometimes the whole plan may even be completely out of order. Therefore, we must be fully psychologically prepared, and we must also believe in students' ability and guide them little by little like educating children. 2. Have a deep foundation. It used to be said that if students were given a bowl of water, teachers should have a bucket of water. Now it seems that this standard is really too low. Students' horizons are widening and they know more and more new things. We should teach such students well and make them progress and improve. Just staying in the study is not enough. While learning book knowledge, we should be diligent in accepting modern scientific and technological information. 3. Have the spirit of research and discussion. Knowledge is an inexhaustible source of energy. A teacher should be a drilling rig with endless life and struggle. Only by continuous learning can they constantly solve old problems and discover new ones, thus improving their own quality and even promoting the development of the whole education. 4. Strengthen the construction of teachers' morality. Learning to be a teacher is a good example. The influence of teachers on students is not only in knowledge, but also in thinking and behavior. High morality leads to high morality, and vice versa. At the same time, teachers' ideological consciousness is improved, so that students can be educated sincerely; Only when teachers' ideological consciousness is improved can they devote themselves wholeheartedly to education, stand on the three-foot platform, be willing to remain uncorrupted and explore and study in poverty all their lives. This is the most basic requirement for every teacher, and it is also a strong guarantee for doing a good job of "teacher-led, student-centered". Quality education is a constant direction, and it is an urgent cause to reform the teaching concept of "teacher-oriented and student-centered". Let's work together for the fragrance of peaches and plums in the garden and the prosperity of the motherland.
