Good learning chemistry Motivation and training have a low level to high, from weak to strong development process, that curious interest → → → love love love → Chemistry teachers often use chemical experiments in light, sound, heat , color change, state change, odor and other strange phenomena caused by students' curiosity, but curiosity is a more primitive, instinctive, unstable tendency of the understanding, followed by teachers and by the vivid and accurate teaching and the nature of contact , use, theory with practice and other teaching tools and methods to guide and consolidate, there are successful operations and encouraged other exams, and gradually developed into the curious interest in interest than the curious to the profound, stable, clear-cut and powerful. On this basis, further development of love, love and love when learning outcomes Chang and honor, ideals and aspirations linked, love, love and love to have a strong emotional and financial will of color, with a stable, durable and strong power characteristics. I just look at how chemistry teaching quality Education, attention to experimental teaching, emphasis on extra-curricular activities, emphasis on practice and study method to explore such issues.


First, the emphasis on experimental teaching

An experimental center, and actively improve classroom teaching, lectures to improve efficiency, reduce the burden on students and enhance students 'physical fitness, improve students' physical and psychological health, scientific and cultural qualities, aesthetic qualities and labor skills. It was suggested: the importance of experimental teaching is an important indicator of quality Education. our chemists Mr. Dai Anbang said: "only to teach chemistry and chemical technology education is one-sided, full of chemical education, requires both knowledge and skills to teach chemistry, but also the training of scientific methods and thinking, but also to cultivate a scientific spirit and character, the students learn in chemistry is the main experiment, the experiment under the guidance of teachers, training to solve chemical problems with the experiment, so that all factors are to develop intelligence, it is a comprehensive chemical chemistry experiment one of the most effective education forms of teaching. "Therefore, we should not in the entrance examination for chemistry experiments testing motor skills than the neglect of the teaching experiment in teaching, we have experiences: chemistry experiments can help students develop and consolidate the basic concepts of chemistry and basic theory, access to chemical knowledge, develop science and technology. through experiments students experimental skills, experiment time and space logistics capabilities, by calculating and weighing experiments can help students form a "quantity" concept? through the "open reagent bottle to be upside down, "the training of motor skills can enable students to develop" opened the cup (or cooker lid, etc. to be upside down "- to prevent pollution of the habit? I believe that the following five Experiments in:
1. Increase opportunities for hands-on labs
Chemical experiments and production of highly skilled, to be repeated many times, be accompanied by rigorous training seriously. I open enough to open Qi Dagang provided by the experimental course, a required course in the optimization of the experimental teaching, the family of small experiments and fun science experiments to strengthen the experimental extra-curricular activities, layout and production practices such as extra-curricular experiments for students to do more practice.

2. Ensure diversity of content experiment
Only the students experiment, for example, to set up the basic operation of chemical experiments, and knowledge-related elements of compounds, exploration and validation experiments of experiments, contact with the primary natural experiment teaching exercises, there is flexibility in the selection reflects the teaching experiment to experiment, and aims to further develop students ability to encourage extra-curricular extra-curricular research experiments and production.

3. Attention to experimental design
In order to cultivate students' ability to open and the primary school teaching in relation to the natural experimental design, such as improvement of the experimental device, determine the optimal dosage of reactants, control of experimental conditions, etc. combined with demonstration experiment, to guide students to the oxidation of concentrated sulfuric acid nature of the oxidation of nitric acid, iodine sublimation pollution on the environment such as the experimental device consists of open to closed type. In addition, in the selection experiment, and experiment with the production of extra-curricular design should focus on its applications and services in real life components.

4. Outstanding demonstration of experimental teaching
In the experimental teaching demonstration experiment to attach great importance to the exemplary role of teachers, strengthen the guidance of the experimental group of students, open lab for students to try experimental design and preparation of the whole process of teaching the natural infiltration of primary research. For example: the teaching of "oxygen and sulfur" in the chapter, taking into account the nature of teaching in the primary oxygen system is difficult to take, so choose to do experiments on the oxygen system of law of the higher-level teaching requirements: learn how to use high-manganese potassium, potassium chlorate, hydrogen peroxide system of oxygen, to grasp the key to the success of the experiment, and in ammonia, methane laboratory system of law, teaching, and just right to reproduce the oxygen system of law, this lesson should be learned, focusing on the process of experiment teaching, allowing students to master and to prepare flexible, the degree of coordination.

5. Comprehensive focus on the scientific quality of education
I experiment from simply teaching tool and as a visual adjunct to the subordinate status of science and educating people to rise to an important and indispensable means of height, through experimental teaching to enable students to achieve mastery of chemical knowledge, experimental skills and scientific methods, to develop scientific attitude and scientific view of nature, learn to use experimental methods to solve practical problems of chemical, so that students receive quality training experiment.


Second, the emphasis on extra-curricular activities

How to do a good job of chemical classes of extra-curricular activities, engage in "live", so as to reap maximum advantage? Through their extra-curricular activities organized class of chemical analysis and synthesis, I believe, lies in the following four points:
1. Students interested in starting from
Great educator Confucius said: "Those who know better than the good, good of the person not the music." Here's a good, fun, in fact, refers to the interest. Interest is the best teacher, extra-curricular activities in the chemical lesson, teachers can stimulate students' interest and curiosity, you can make the students the desire and interest for a time, bring together to promote student learning and development of lasting power. from the following two aspects:
(1 activity course content should be rich
The phenomenon of ever-changing chemistry, chemical processes are simple but also complex, plus extra-curricular activities, there is no fixed course materials, which requires teachers to choose content-rich, properly, to avoid a single, boring, according to the psychological characteristics of junior high school and one semester teaching situation, extra-curricular activities in chemistry class, students interested in the larger are: first, the choice of content and students the knowledge learned in the textbooks are closely linked, is an extension of textbook knowledge, students learned to use the theories and knowledge to guide practice, will greatly stimulate the interest of students to mobilize their enthusiasm, such as: learning a carbon adsorption of nature, organizing students to the system using activated carbon and charcoal water purifier production of extra-curricular activities. Second, the choice of content to be close to life, to occur in the material side of the chemical phenomena in early on, I organize students to create some simple chemical products, such as ink, students feel both fresh and practical. Third, the selected content chemical on the number of challenges, to attract the interest of students and mission.

(2 forms of organization to be flexible
Content as cooking materials, a good material to add a good match methods and cooking methods, it would make a good food to Chemical extra-curricular activities, classes, too, with good content, but also the flexibility to choose activities way, so as not boring, have the effect will be more effective.

There are many classes of chemical activities, extracurricular activities, such as chemical experiments, special reports, chemical production, chemical evening, chemistry competition, etc. As the saying goes: "Education is not fixed." Similarly, extra-curricular activities, class activities, chemical way is not fixed , according to the different content and flexible way to choose activities such as: interesting experiment, do not simply organize students to experiment, can be in the form of magic, mystery increase student interest and curiosity will surge, effect will be greater.

Extra-curricular activities, classroom lessons are supplemented and extended, so that extra-curricular activities in order to truly become a second class lesson, to be in the basic theory, basic knowledge and basic skills do a lot. Requires active class understand the basic principles in the experiment, to master the basics of lesson activities and related knowledge points and textbooks linked, so that students can deepen the understanding of basic knowledge, but also contribute to memory, so that curricular and extra-curricular closely.

3. In the course, pay close attention to students' abilities
Ability to carry out extra-curricular activity classes is the main task. Capabilities include observation, hands-on skills, thinking skills and creative abilities in extra-curricular activities, classes, teachers should find ways to improve all aspects of students' ability to do better This is, first of all should give full play to the autonomy of the students, allow students to independently active, independently operating, independent thinking, self-creating, and truly become masters of the activities. the general student self-activity time course of time not less than the whole event 3 / 4. Throughout Kewaihuodong lesson, students are "players", the teacher is "off-site guidance" such as: the preparation of soft drinks in extra-curricular experiment, I ask students to prepare before the experiment to do the following:
(1 review books with the experimental knowledge about the content.

(2 access to information, to identify the necessary experimental drugs and formulations.

(3 proposed experimental procedure.

(4 envisaged experimental phenomena and problems that may occur.

During the experiment, students can independently carry out experiments, and continue to improve the experiment, until a satisfactory test results the teacher only for appropriate inspiration and guidance that a student's learning ability, observation ability, thinking ability and so to get a comprehensive The training activities also in the process, should promote the students to ask questions or do other experiments and if the students raised the issue, as evidenced by the students through the observation and reflection, then the teacher should make every effort to answer students' questions or to meet experimental needs of students, teachers must not evade or perfunctory, of course, ability to do overnight, so in chemistry class in extra-curricular activities have a purpose, constantly training and training for students.

4. In the course, students rigorous and meticulous attention to scientific approach
Chemistry is the basis of experimental study of physical changes and the laws of natural sciences, there is no rigorous and meticulous attitude is not enough, the cultivation of this attitude from the beginning students to learn chemistry, I started this regard, there is a unique chemical class of extra-curricular activities favorable conditions, first experiment requires students to not miss the tiny anomalies, should be asked at the end of trace, until the issue is resolved. History shows that sometimes it is the small problem may have a big discovery. Secondly, in the event of content should have certain degree of difficulty and "precision." such as: I arrange for students to develop rules, large copper sulfate crystals in this experiment, the results of some students blindly confident, careless, trained irregular or defective crystals and even Some students just develop many small crystals. Use this example to inspire them to analyze the failure, pointing out that this experiment required drugs and equipment are very strict, if a little attention, to act rashly will come to naught through this activity, students wrote in the summary: "appears simple, but doing it is not easy, if sloppy, lose the least bit of difference of a thousand miles. "
With the curriculum reform, the chemical class in extra-curricular activities are also subject teaching chemistry gradually is especially important, so we should pay attention to it, less chemical knowledge to overcome the students, there is no need for extra-curricular activities, misconception, and in the process of teaching continue to explore, summarize, the chemical class and made of flesh and blood extra-curricular activities, so as to reap the greatest advantage, and comprehensively improve the quality of students in a unique role to play.


Third, attach importance to the study of law and practice guidance

As we all know, students self-learning ability is very important. So, how to develop it? I believe that there are two ways that merit our attention, first, to guide reading, the second is to guide practice. To guide reading is well-organized, planned, destination guide training students to read, especially recommended: The best reading material is material. a new junior high school chemistry textbook illustrations, intellectual, readable. And the match coincided with the classroom, play a preview of both the role and achievements in the classroom to make learning timely verification, thereby enhancing students' self-confidence and inspire students to self-interest of teachers to make appropriate reading tasks - - To solve the problem. teachers teaching in the text, image pictures, and data analysis should help students to summarize. to guide practice, including two aspects: First, students select the appropriate exercises to enable students to non-means the sea of ​​suffering. If the words of exercises divided into two categories, one is for the students time to digest and consolidate new knowledge, new learning content and the assimilation of existing knowledge, knowledge into their system by so-called " formative exercises. "The other is to improve the problem, that a knowledge of different aspects and points from different depths revealed that when the knowledge of a comprehensive problem-solving deep understanding in order to achieve mastery, the effect of replication also requires the use of analogy, analysis, summarizing, synthesizing a variety of ways of thinking, so that the breadth of thinking, agility, tight, creative thinking and other effective quality training. The second is to explain through a typical exercise, not only teach students problem-solving skills, but more important is to guide students through exercises to learn to organize knowledge so that knowledge in mind a clear, principled, network, therefore, an exercise done after each to reflect thinking.

classroom teaching is imparting knowledge to students the main channel, we must strive to improve, reform should reflect the teaching-oriented, science as the main principle of training as the main line of thinking, speaking with the method, a large area for the purpose of improving the quality of teaching. Teaching , I use the "clear objectives - self-exploration - succinctly and key - diagnostic practice - remedial target" approach, popular with students and have achieved remarkable results. teaching, I have to teach students a variety of learning methods, such as science and reading method eight aspects of learning, action learning, learning the topic and so on, trying to do to teach him to fish, so that students develop good sees the big picture, to grasp the structure, seize the key points of good practice analysis.

In summary, the outstanding quality of education in chemistry education problems, we should raise awareness, two to truly implement, the only way to receive effective
