Abstract: In the reform of the new curriculums, for the purpose of increasing the levels of the physics teaching in the junior middle schools in China, the most important thing is to make an enhancement to the qualities of the physics teaching. In this paper, from the perspective of the psychological characteristics of the students in the junior middle schools, the author mainly gives a study on how to improve the knowledge fundamentals and experimental skills of these students, train them to possess a good psychological quality and a comprehensive quality at the same time, and finally puts forward a few of suggestions for the improvement of the physics teaching at the junior middle schools as a whole.
Keywords: Physics of Junior Middle Schools, Experiment Teaching, Improving Teaching Levels
Both observation and experiment are two fundamental methods of researching and learning the physics. For this reason, from the aspect of the physics teaching contents, the author designs a large number of the demonstrative experiments and the quantitative student-grouping experiments, for the purpose of promoting the students at the junior middle schools to absorb the knowledge in physics on the basis of observation and experiment. As a result, during the process of teaching, it is necessary for the teachers to seriously do a good job of every demonstrative experiment in the textbooks first so as to instruct the students to complete all kinds of the grouping experiments in the textbooks, and then give prominence to the characteristics of the physics and open up a number of new experiments with flexibility in accordance with the teaching requirements and the knowledge of the students, with a view to driving the students in the junior middle schools to论文导读：le1,itcanbeknownbypeoplethattherearestill15percentagesoftheleaderromthejuniormiddleschoolsinNanningcitytothinkthephys上一页123456下一页

middle schools, which are complied under the new standards for curriculums, the number and contents of the physical experiments are increased to a great extent. However, in face of these changes, the junior middle schools do not enlarge the intensity of the investments on the teaching facilities, experiment equipments and others which are necessary for the physics courses in time, which gives rise to the situation that the supply cannot keep pace with the increasing demand. What is more, in some schools, multiple teachers even abandon themselves to "reading" the physics experiments and also many students are used to "reciting" the circumstances of the experiments mechanically; the phenomena that "the students try to connect the circuits on the exercise books when the teachers are making adjustments to balances" are highly frequent to take place at the physics classrooms. In the following, the attitudes of the leaders of all Nanning Junior High Schools, which were investigated and researched in the "Survey of Physical Experiment Teaching in Junior High Schools in Nanning District and its Reflection" of teacher Yan Jingliu, teacher Yi Qishun and teacher Wei Jinming, will be introduced by the author in details in this paper.From the table 1, it can be known by people that there are still 15 percentages of the leaders from the junior middle schools in Nanning city to think the phys论文导读：ouslyareverypoorinthepracticalability,theywillbringadirectnegativeinfluenceonthestudentsatthejuniormiddleschools,andwillmakethestudentsgetanincompleteunderstandingoftheknowledgeinphysicsandpoorintheexperimentfundamentals,e上一页123456下一页
ics experiments are of no importance at the present time, and the importance which is attached by these junior middle schools to the physics experiment teaching is not enough as well. Therefore, it is highly necessary for the leaders and teachers at the junior middle schools to deepen the understanding of the physics experiment teaching, for the purpose of providing powerful guarantees. At the same time, from the table 2, it can be learnt that the funds which are invested by the junior middle schools on the physics experiment teaching are far away from sufficiency, and there are 15.6% schools to be in shortage of the physics experiment teaching very seriously, and the students are still receiving the physics experiment teaching in which they are only necessary to listen but not to do practically. Therefore, in order to adapt to the requirements of the new reform of curriculums, it is necessary for the schools to increase the investments on the laboratories, teaching facilities and experiment equipments, and also provide more opportunities fo怎么写论文www.7ctime.com
r the students to participate in all kinds of experiments. In this way, the quality and level of the physics experiment teaching in the junior middle schools are able to be enhanced fundamentally.
1.2 Experimental Level of Teachers is Necessary to be improved continuously
The teachers play a highly important guiding function in the physics experiment teaching. Therefore, supposing that the teachers in physics he a low experiment level, and simultaneously are very poor in the practical ability, they will bring a direct negative influence on the students at the junior middle schools, and will make the students get an incomplete understanding of the knowledge in physics and poor in the experiment fundamentals, e论文导读：ionarewastedaswell.Besides,afterclasses,thestudentsareaskedbytheteacherstoonlyrecitetheresultsoftheseexperimentphenomena.Thus,thestudentsinthejuniormiddleschoolsareabletoonlygetanunderstandingofthelearntknowledgeinphysicsatthememorylevel,andcan’tex
tc. As the conditions of the physics experiments were rather poor, there were some teachers who did not know how to replace and connect fuses, and establish the simple lighting circuits. Under the circumstances, these teachers fall into a habit that they do not make the experiments usually. What’s worse, the old teachers do not like to do something with their own hands, while the young teachers only imitate what the old ones do. From these, it can be known that it is doubtless for the improvement of the experiment fundamentals of the students to be nothing but an empty talk. In addition, some teachers do not set up the goals of the physics experiments properly at the experiment classes, and simultaneously can’t clearly tell their students how to observe the phenomena in the physics experiments and link the phenomena with the rules which will be inspected and verified. As a result, an experiment class is quickly over in the blink of an eye, and finally the resources of education are wasted as well. Besides, after classes, the students are asked by the teachers to only recite the results of these experiment phenomena. Thus, the students in the junior middle schools are able to only get an understanding of the learnt knowledge in physics at the memory level, and can’t exert the important roles of the experiment teaching to the maximum at the same time.源于：毕业论文致谢www.7ctime.com

Afterwards, the students are guided by the teachers to observe the changing rules of the object distance, image distance and image size in the experiment process again and simultaneously make conclusions as shown in the following.
When the object distance changes, the image distance and image size simultaneously;

ce as large as the focal distance (i.e. under the circumstances of the real imaging), the larger the object distance is, and the aller the image distance will be, and also the aller the image will be. On the contrary, the image becomes larger, and the image distance will certainly be larger as well, and the object distance will certainly be aller.
At the moment the students in the junior middle schools are able to independently make researches on all kinds of physical phenomena at the classes, they will certainly become highly interested in the physics, and simultaneously their curiosities will attain a complete satiaction. In addition, by means of the explorations on the experiments to make conclusions, the characteristics and changing rules of the convex imaging will be understood and remembered with higher accuracies and solidness, and also can be applied with more proficiency and flexibility. As a result, the teaching efficiencies at classrooms can be significantly enhanced to a great extent.

4. Conclusion

From the above analysis, it can be known that physics is an experiment science, and the experiments are the foundation for physics. All concepts, rules, formulas and others in physics are grounded on the objective experiments. In other words, the theories in physics can never be divorced from the inspections and verifications of the results of the physics experiments. As a result, it is necessary for the teachers to give effective instructions to the students at the junior middle schools so as to make attempts to do practices on purpose, which are the positive explorations on the nature and also can make an enhancement to the whole level of the physics teaching.
