Part of the basic operations of chemical experiments in the To meet the experimental operation Graduates of junior high school exams, I as a chemistry teacher, the students the basic operation of chemical guidance and training. is that the more common error, and clearly the correct method of operation, would like to draw attention and possible to correct errors in a timely manner.
1.
error point holding the tube: hand grabbed the ring finger and little finger or extend; the upper or the lower position.
the right way: Two three-finger grip means fist. tube
error point: holding test tube in the middle or lower jitter.
the right way: fingers should be the experimental results. oscillations in vitro, use the power swing wrist, arm does not shake, draw the bottom arc tube movement, so that the solution to oscillate the tube, not up and down Britain, to prevent spillage.
3. cylinder use
Error points: A. hand holding a graduated cylinder readings; B. readings, some vertical, some looking up; C. some can not be taken based on the amount of liquid required select the appropriate range of cylinder sizes. D. adds a liquid, but also with suck out the dropper.
right way: Use the graduated cylinder should be taken according to the amount of volume of liquid required, you can choose to take a minimum amount of specification cylinders. operating essentials is mouth, free flight; change dropping to scale; reading, line of sight to maintain the lowest level with the surface. tube drops to the scale at.
4. dissolved salt mixing operation when the error point
: A. dissolving salt given the mixing process using a glass rod Voice of Doraemon; B. glass rod in the upper part of the liquid mixing.
The right approach: operation level when the beaker on the table, the first adding solid salt, then add the appropriate amount of water, hold the glass rod at one end of the 1 / 3, glass rod the other end of air extending beaker beaker of liquid in the middle or along the wall, alternately clockwise and counterclockwise circumferential movement doing, the rate is not too fast, the force is not large, glass beaker wall can not be issued a jingle of the collision sound.
5.
instrument connection errors point: the glass tube hard to press the rubber stopper or hoses; removed when tugged; hand bend at the pipe break hard to force the hand to be punctured.
the right way: wetting, a little harder turning into the can. tube into the mouth should be plugged to slowly turn the cork. plug into the nozzle size in order to plug some of the 1 / 3 right. demolition and installation time should be a little hard in the opposite direction when turning aside. < br> 6.
device error checking tightness point: Operating in reverse order (first holding test tube, after the test tube immersed in water); device leakage or conduit opening are not exposed to the bubble, I do not know where to start to find reasons.
right way: one end of the first catheter into the water, then heating the container by hand stick, due to thermal expansion of air inside the container, there are bubbles escape tube mouth, release your hand cool for a while, the water to rise along the catheter, the formation of a water column. This shows that a good gas-tight device.
closely linked to text teaching students reading Yongnian County, Hebei Province

first experimental school teaching English reading purpose is to teach students reading method, the training of their reading skills, develop and improve their reading comprehension. And in recent years, questions in the test of English reading not only increase the amount of the title means more emphasis on students reading ability of the test. Therefore, traditional analysis of the verbatim text to explain the language, let the students take notes of the teaching methods were not suited to the new form of teaching. So how effective use of new materials, to train and develop their reading ability? I think the following should be done from:
First, pre-class preparation
including teacher preparation and student are expected to preview the two parts.
1, teacher preparation should include the development of teaching methods
, well-designed lesson plans, multimedia courseware and prepare carefully supplementary material.
illustrated the existing junior high school English textbooks, genre variety, involving a wide range. Therefore, in reading instruction, you should read the text for the content of each unit, targeted use and supporting the use of the image reading instruction, teaching or preparation and the CD-ROM Materials related to the slide, stick figure, objects, films, events.
2, students preview
different types according to the text, to preview the different requirements of students to prepare and guide students to preview.
two new courses Import Import
innovative and flexible ways to stimulate student interest in reading. teachers should be based on different content in different ways of teaching.
1, import
situations through pictures, music or multimedia to introduce students to a new screen will lesson.
2, suspense
suspense will leave a big space to think of students, but also make them eager to learn what anomalies.
3, with practice, there are many English texts
and the actual link to.
Third, read the guide
how to use good material, to develop their reading skills is a crucial point. normally takes three steps:
1, crude Reading
require students to quickly read the text and answer questions 1-2 posed by the teacher. This two questions should be simple. students generally able to find the answer right away. to enable students to find the center of each sentence, but also develop students reading skills a good way.
2, the purpose of Intensive Intensive
a deeper understanding of the text is to understand the author's views and intentions. INTENSIVE class teachers should not only stay in the key words of explanation, but should focus on understanding of texts, develop reading skills.
3, expansion of reading
students mastered the rough idea and specific facts, teachers should guide them will have the knowledge and practical links to help them understand exactly Articles characteristics of the underlying intent and meaning of the article. For some of the details of the sentence, and then guide students to read, understand its meaning. and on this basis, to discuss the text, or other skills training. In addition, the article can also arrange for students be rewritten, extended writing, abbreviations, and writing, to repeat the article. Also, teachers should select the text content of the reading material available to students to read, to increase its amount of information, expand their knowledge.
All in all, as English teachers should adapt to new forms, to adjust their way of thinking, as soon as possible from the traditional teacher-centered teaching methods, to new, science, teacher-led, student-centered teaching methods change, really research study to infiltrate the concept of English teaching.
of multimedia technology in primary school language teaching
Fengfeng mine, Handan, Xinhua Yang Xueqin
primary application of multimedia assisted language teaching is a high efficiency of modern teaching methods, which allow students to remain excited about learning, pleasure, desire motivated state of mind. multimedia on the student body of the play, innovation and the cultivation of the spirit of exploration has a multiplier effect. The emergence of multimedia technology for our improvement of teaching methods has provided new opportunities for development of multimedia technology and the integration of teaching, resulting in the optimization of the teaching effect.
a multimedia into the classroom, helping improve the efficiency of language teaching.
computer multimedia technology scientific nature of computer interaction, feedback and other characteristics, in the teaching process financial picture, text, sound, like in one, is an intelligent two-way process of teaching activities. multimedia technology also greatly simplifies the operation of the teachers so that teachers can concentrate on teaching itself, thus greatly improving the classroom teaching.
1, the use of multimedia computer image, visual effects, to resolve difficulties. the use of computer teaching can effectively abstract for the concrete to hard to understand content or play an important role on the understanding of the text content, using a computer to show up, mobilize the students of visual function, through the visual image, vivid sensory stimulation, so that students maximize their potential, in the limited time, all-round perception more information, improve teaching efficiency and learning of the internal activation.
2, using multimedia to help students understand the ancient poetry. poetry teaching using electronic teaching media and reasonable use, not only help to stimulate students interest in learning, development of student imagination, and promote understanding of student learning poetry, but also effectively develop their aesthetic sentiment.
3, the use of multimedia computer, and inspire students to enjoy writing. With interest, resulting in a desire to write, writing can be hard, thereby enhancing the effect of composition teaching.
4, the use of multimedia, scenario representation, cultivating originality of thinking. In reading instruction, the computer as a cognitive tool, the students demonstrate the thinking process and the combination of animation, the use of divergent thinking, develop powers of observation and imagination, so that students show a distinctive personality with the answer to.
Second, multimedia in-depth class will help improve the quality of their language.
multimedia courseware for students vivid teaching situation, a variety of teaching resources for students to create a colorful, audio and video synchronization, dynamic to static instructional situations enable students to eyes, ears, mouth, hands, brain and other senses also accept incentives to students in hands and brain, thinking focus, strong in the language classroom to promote students listening, speaking, reading and writing and enhance the use of comprehensive ability, thereby improving the overall quality of all aspects of the students.
special emphasis on quality education of modern education, the emphasis on the quality of people across the board. Therefore, the teaching is not just imparting knowledge, but also the process of capacity development is to enable students to become independent by learning, and ultimately out of the trust teachers to become independent of people in learning. Language Division's mission is to improve the quality of student language. It includes two aspects: one, to teach language knowledge, training, language proficiency; the other hand, raise the ideological level, expand the knowledge horizons, rich in paragraph literacy, personality exercise will cultivate aesthetic other.
If language teaching is a blooming flower, then multimedia is a green icing on the cake, the two complement each other and each other one, the creation of a pleasure to the students an interesting situation, to improve the language quality of teaching.
to the mathematics classroom into a paradise for students to independently explore Fengfeng mine in Handan City, Hebei Province
Zhang F, Cheng Aiqing
primary school mathematics curriculum standards that promote self-study, student activities should be A lively and active and full of personality process. Therefore, the mathematics teaching to inspire students should be to maximize the positive process of mathematical practice. should allow students cheerfully into the mathematical world, to stir up interest in the exploration, to seek pleasure from the discovery of the initiative to acquire knowledge, to understand the value and use mathematics to full of fun, exploratory scenarios, for example, addition word problems in teaching, the authors present a group of mushrooms in the wild rabbit picture, and asked a total of a few rabbits. see this funny picture, very naturally into the students scenarios, with their careful observation, discussion with interest, with a variety of results: one is left with the right side of the 8 rabbits 7 rabbits, a total of 15 rabbits; the other is 10 white gray rabbit with five rabbits; students also found that: to see with the eyes can not see eye 9 6; bend which does not bend the ear of the ear; see invisible tail with the tail. In the teacher's guide Next, the students involved in the expression of mathematical thinking and other activities, are very interested.
emphasis on students existing mathematical knowledge and life experience comes from life, Life is full of mathematics. the author of ; the teaching, in life many students are familiar with the object selected. such as small ball, table tennis, building blocks, toothpaste boxes and other shapes of objects, put them in a bag, four bags, and asked the students want know what the backpack? this way, the only fully captured the curiosity of students, but also enable students to learn quickly into the best condition. When students poured out the bag of things, I would once again the use of children good fun moving nature, said: .
provide sufficient time and space the students are learning the subject, children's nature is lively, willing the event secondary knowledge. in the traditional classroom, too serious ; of cliches, often to the enthusiasm of self-exploration repressed. Therefore, in the classroom teaching, students must be given adequate time and space for independent study, let go and allow students to participate in learning activities.
way for autonomous learning from the evaluation of offers dynamic evaluation methods and encourage the performance of the diversity of students to be more aggressive, more self-involved in the study, the driving force for the provision of their own learning. such as teaching the students to talk about with the point method, and some number of law by then, some think of the be encouraged, and to provide students with an opportunity to communicate to each other between the students inspired, learn from each other, so as to continuously improve their methods. highlighted the concept. In the evaluation, as long as the students progress bit by bit, I will be a red flag in recognition and awards, such as speak truth, the distinctive red star on the award. This raised the enthusiasm of the students, especially those with learning difficulties After the students get recognition even greater progress.
of multimedia and physics teaching school thirty-second of Handan City, Hebei Province Hu Junfeng
rapid development of multimedia teaching of information technology applications in the important field of education , has become an important adjunct to classroom teaching and identify the basic requirements of Teachers, courseware has become an essential complement to classroom teaching, teaching activities to provide a flexible way, the advantages of courseware to replace it and the projector slides, especially for the experiment based on the physics will be more widely used, replaces much momentum physics demonstration experiment. However, the people of multimedia courseware in the classroom teaching position and lack of understanding of the role, it application results did not meet, but make it a fashionable show and some fool head open class finishes, I think that is a serious misunderstanding.
first: multi-media teaching does have a certain role in support of teaching information technology, high-speed
development of knowledge representation can be multimedia, we need some of the more advanced technological knowledge, students can broaden their horizons through multi-media show to students, can be illustrated to the students, a variety of forms of knowledge, but also can in the normal school to show some of the more abstract knowledge to the students, it has to stimulate students interest, improve the efficiency of the effectiveness of classroom teaching, such as: electricity, magnetism, molecular thermal motion, the current invisible, intangible, magnetic induction lines are read not seen, touched, molecular movement, molecular invisible, intangible, hands-on experiments have only seen the phenomenon, to get the final results, in the middle can not observe the process, and no observations, then we can make this part of the multimedia courseware can , multi-media teaching and other teaching methods should be combined with each other to increase the diversity of the classroom so that students have a sense of novelty, and will not be too monotonous, and enhance interest in learning but can also provide a comprehensive variety of sensory stimulation, 45 minutes to maximize the effectiveness of the classroom to increase the number of access to information, classroom to get the knowledge they need.
Second: the limitations of the multimedia courseware using multimedia courseware
good side, but also its limitations. courseware can describe the physical facts, indeed can not verify the physical facts. After all, is a design
pull of gravity G and F of the size of the relationship between the length of rope stretched between the object rising height ratio between
. and then let the students read through in the classroom, so too, after all, the classroom procedures, are on paper, unrealistic, seriously hurt the students the motivation to learn yourself, lost the significance of students creative thinking, to curb the abilities of students, on the intellectual development of students more harm than good, like a tuning fork vibration, sparking a wave experiments; The effect of stress and pressure and the relationship between the force area; charged objects attract the nature of light small objects; determine resistance factors and so on, try not to use the courseware, through things, experiment; through an intuitive phenomenon, not only can stimulate students interest in learning, also mobilized the students attention.
Third, the application should have a certain degree of multimedia teaching
Multimedia is a technology, a tool not only for the quality of education services, but also for examination-oriented education services. just the beginning of class, teachers use multimedia tools, students feel more curious, and lectures effect is quite good, but some teachers over-pursuit, obsession multimedia simulation experiments, to replace the demonstration experiment with multimedia courseware and student experiments, drop a reputation as the use of modern teaching methods to enable students to see if they do not attach importance to the students to see real and practical, this lead to disastrous consequences. In short, do not do now or less considerable number of teachers to experiment, to give up the use of experimental visual teaching methods. Innovative Education is not out of thin air the fabrications, but by observation of objective level objects, analyze, summarize, up in the basis of objective facts are the results of previous conclusions have not been, or is the correct conclusion predecessors to create a new field. If the teacher whether on what type of class, the total use of multimedia, over time, students no longer have fresh, and got tired, emotional aversion, not only will not achieve good results, but will seriously hamper the ability to develop creative talents, so that applications must have a degree.
innovative education should not be just a trendy and loud slogans, but should fall on the most practical place to work. Teaching is an art, teaching, through the emotional cross contamination between teachers and students to mobilize students motivation to learn, any form of teaching is only a prop in the hands of teachers, teacher-led teaching activities only, the students are the main body. respect for science, facts, face the group, to test the premise of innovation and education to enable students to master the skills of physical experiment and the scientific method, to develop scientific experiment teaching objectives, the modern teaching methods and teaching with the actual conduct of science in order to achieve the desired results.
political teaching of innovative teaching middle school in Hebei Province
Feixiang North High School Wang Ruiju
present, emphasis on moral education has become a world trend. Both developed and developing countries, have seen the necessity of moral education and the urgency of implementation. China is a developing countries, modernization has just started, there have been economies of Western countries, first, money worship, moral decline and other negative phenomena in our social life has been reflected. We must pay more attention to moral education of the young generation to fully understand the ideological and political course position. Only in this way will ensure the improvement of quality education, thus creating the basis for modernization.
depends on the level of teaching quality the merits of teaching methods. the traditional injection teaching, long throw in the garbage of history heap. current ideological and political course of the multi-modal teaching methods varied, but I think had to adopt innovative teaching methods.
well-known, quality education lies in students the spirit of innovation and practical ability, no doubt, ideological and political course Teachers must be skilled master and apply innovative teaching methods.
should focus on the development of innovative teaching students the spirit of innovation, creativity, innovation, innovative personality to start teaching the four basic objectives. because of innovative teaching is a systematic project involving to teaching ideas, teaching content, teaching methods, teaching methods, teaching management, teaching evaluation and other aspects of reform, and here I speak mainly of teachers teaching in the classroom teaching of innovation, from the perspective of teaching, innovative teaching methods the following points.
cited without fat: teachers spoke of the crucial place, suddenly stopped, leaving suspense inspire students to speak out below. so bold and innovative thinking of students; or nodules in the classroom, it will be deliberately left the issue of interest to students to encourage students to use their spare time to study, will undoubtedly improve their innovation capability.
scene of: teachers, head to, there are plans to create a form of truth, love cutting, will, Li Yun, think fun, beauty of teaching situations and to expand the analysis of this guide, you can develop students ability to innovate.
Zhiyiwennan: in the teaching process, the time to seize some of the favorable opportunity, the value of some problems with thinking you can activate the students thinking, develop their innovative thinking ability. innovative hard problem but also the quality of the following three points: a, the problem is not a single standard answers; b, the answer is not limited to the existing teaching materials; c, the problem is student's knowledge state Syria based on experience.
dialectical analysis: in the teaching process, error. Therefore, teachers should focus on guiding students to use the dialectical point of view to observe and analyze social phenomena, in order to cultivate and improve students ability to correct view of social phenomena.
organize the discussion: class discussion is to activate students thinking and stimulate students of innovation an effective form. in the teaching process, teachers create conflicts with the destination, and put forward their own insights, innovation can also inspire students to learn.
multi-dimensional training: the innovative ability of students rely on teachers, teaching is by no means must also strengthen the training. and this training must not engage in Some say, in the innovation teaching will always be used. I think that is conducive to promoting the teaching we have to use. to political teaching and the inexhaustible power lies in innovation.
optimization politics teaching students creative thinking ability seventh high school in Handan City, Hebei Province
Liu Hongyan
hh an inexhaustible motive force for the prosperity of innovation nation not difficult to stand in the world's advanced nations. depends on innovation and education. Therefore, China's Education Reform for the 21st century an extremely important task, that is, full implementation of the quality of the education process, the implementation of innovative education, students of innovation and spirit, to develop their innovative potential, increase their ability to innovate. I'm teaching in political science try to do the following.
a socialist market economic characteristics, optimizing the political structure of teaching content and teaching students develop creative thinking
mm political teaching first optimization teaching content and teaching structure. political science with a high degree of system and perfect logic, it is systematic and perfect logic implicit in the material structure. taking into account high school students already have a certain amount of thinking ability, but also certain language skills, I change the traditional teaching practices, first revealed in a chapter or a part of the overall knowledge structure, the overall situation for students and teachers in understanding the material, recognizing cues conditions, for each local study, teachers and students to enrich the knowledge framework. students in the overall knowledge, based on a variety of natural features to explore the differences between them, such as the meaning, causes, effects, etc., and guide students to compare the capitalist market economy with socialist characteristics of the nature differences to arrive at a socialist market economy than the capitalist market economy run better.
Second, optimizing and political teaching methods innovative thinking
mm of students to teaching examination-oriented education is emphasized as teachers in the teaching the main, the students are basically passive acceptance of knowledge objects to contain the students the formation and development of innovative thinking. the quality of education in the political class is different, it is seriously thinking ability of students, and teachers in the classroom is precisely to guide students face to face important place to think. Therefore, teaching must be inspired teaching center, to the student, the knowledge transfer process at the same time as the students thinking process, creativity and ability of the process.
1, the total learning and thinking starting from the problem, learning is a process of continually asking questions received. in the teaching process, questioning suspects often use design inspiration. intended to create difficult, or that the value of any thought with interesting problems, leads from our mistakes the correct answer, the students particularly impressed, much better than her bluntly explained.
2, students in the main method. student body law mainly refers to teachers teaching in the political process, has always been the students as a teaching center, a properly guidance and fully mobilized, as well as possible learning to play the initiative and enthusiasm of teaching methods.
3, the optimization of the method taught political lessons, but also focus on guiding students to learn the method. do teachers to create awareness situation and found that the combination of the students themselves, teachers, guidance and coaching to solve the problem of combining the students themselves, teachers to teach the knowledge and teaching methods combined. Marx's own ideas and methods of economics so that students can take the non-poor, inexhaustible. capacity
teaching environment is a special environment. optimize teaching and learning environment, according to the teaching activities, the teaching environment constantly adjust the controls necessary to capture the physical and mental development in which human factors have positive and eliminate inconsistent development needs of the factors that make teaching and learning environment conducive to teaching and learning activities towards the direction of the smooth development.
1, to create a democratic, free, to create an atmosphere of collective security, and tap their creative potential. for classroom teaching, is to minimize student behavior and thinking of the restrictions that have had a free ride, free expression of the opportunity. the teaching of both enthusiasm and mobilize the initiative, highlighting the leading teaching and learning of subjectivity, and to cultivate creative ability.
2 , give full play to the role of a large classroom environment. mainly using the new character of the construction of new events, new materials, new hot spot for the education of students live. It can not only inspire students patriotism and socialism, passion, more broadening cultural knowledge of students, multi-angle multi-lateral teaching materials to help students understand the basic concepts and principles.
politics teaching in the optimization of training creative thinking process, teachers should effectively change the concept of education. from the injection type exam-oriented education to enhance the whole concept of national quality innovative educational concepts, training creative thinking ability is a prerequisite. to the requirements of even higher quality of teachers, more teachers need to constantly upgrade their quality, innovation and education to assume the core of the national the historical mission of quality education.
On the ideal of politics teaching in Handan City, Hebei Province Education
Wang Hongbing
the first vocational high school vocational secondary and political teaching duties to the students outlook, career outlook , and the world the important task of education in the country's largest independent innovation environment, adapt to the new political situation and do a good job teaching is very important, which is the political ideal education teaching the proper meaning of the title.
First, students should be firmly established
lofty ideal of communism is the ideal goal in life is that people on reality based on the desire and pursuit of the future, the ideal press consists of: social ideals, moral ideals, career aspirations, ideals in life and so on, which, is the most fundamental social ideal, the ideal play a major role. it runs through the ideals of the other, but also the ideal basis for a person and end all. Our ideal is to firmly establish communist society lofty ideals, high school students are in life, view of the world formed an important period, they must be communist ideals of education. Students must be firm must first establish communist ideals correctly understand the meaning of communism, communism is under the guidance of Marxism, the communist social system in order to achieve the great carried out practice. There are three meanings: First, communism is a social system that the communist system, according to Marx's discussion of the social product in this system extremely abundant, people do everything according to need, Labor is no longer a means of livelihood, but first needs. Second, communism is a theory that communist theory, that is, the theory of Marxism. Third, communism is a practice that, in order to achieve communism social system and to the great movement.
Second, in teaching students to understand: the ideal of communism is based on a scientific basis.
Comrade Hu Jintao pointed out: , is built on Marxism reveals the development of human society based on law, which is a scientific ideals and beliefs. social ideal, to the Modern Three utopian socialists, are fascinating portrayal of the future, but before the birth of Marxism, all this inevitably limited to the fantasy or illusion, and ultimately can not be achieved, and the residual value of Marx's Historical Materialism founder of the theory of socialism by the fantasy eventually become science.
She told us: production of material existence and development of human society, the foundation of the productive forces and production relations of contradiction is the driving force of social development, social productivity The ultimate decision power. development of human society is not a people's will as an objective historical process, instead of the original slave society, feudal society replaced slave society, feudal society instead of a capitalist society, socialist society instead of a capitalist society the general trend of social development, people are the masters of history, people make their own history. capitalist society is the highest form of private ownership society, its basic feature is the socialization of production, but production is occupied by a few capitalists , which formed a production and capitalist social contradiction between private ownership, this contradiction is the fundamental contradiction of capitalism, beginning with a confrontational and always through a capitalist society, capitalism itself can not overcome, as social development, the contradictions and the resulting intensification of the end to the other contradictions of capitalism into the grave.
three education students in the teaching process
properly handle the relations between the two first, handle the the highest ideal and a common ideal relationship. Our highest ideal is to realize communism, the common ideals of our people at this stage of building socialism with Chinese characteristics, to build China into a prosperous, democratic and civilized modern socialist country. both a dialectical relationship between unity and common vision is to achieve the highest ideals of the foundation and necessary step to realize the highest ideal of the common good must be the fundamental direction, so we establish a socialist market economy in the process to to both
