Medium test physics to review a method
Medium test physics to review a method
-Aim at to review half effort and double results
The beginning is three classmates and test in close to of end of two how with in the week carry on the overall to the junior high school physics, aim at sex of, effectively review, attaining the effect following opinion of half effort and double results thus can provide the classmates the reference:
A, research 《test a key link 》, reads teaching material
《Test a key link 》BE the basic request of teaching, it ruled medium scope and request for test, is medium test to set question of one of the basis, for in test to review a function of have the importance.Pass a rightness 《test a key link 》of research, the request of explicit examination, understanding type and make to review a direction ownly to the student's ability request, there is target, making to review ownly can have an explicit evaluation basis, be advantageous to wide degree and depth that the confidence review thus, make to review to have more of put Shi.At research 《test a key link 》of in the meantime, also want to cautiously read teaching material, because the teaching material is the root of the classroom teaching basis, is also in test to set question of one of the basis.The classmates must cautiously read teaching material and specially want to notice a few following aspects in the teaching material:
(1)The science method of process and chaperonage that physical concept and regulation become.In the last few years of in test physics to try in, be worth and share to 10% or so for this kind of cent of topic.In the junior high school physical teaching material, physical concept and regulation become of process usually what to adopt be "the control change to measure a method".Such as:the speed, the density, press strong, the specific heat permits formation process of wait the concept, Mu laws in Europe, influence liquid evaporate rate of speed of factor, influence electric resistance size of factor, liquid inner part press strong regulation, Archimedes' axioms waits get of physical regulation etc., is all what the adoption"explore to make to change to measure a method" come carry on a research.The last few years of medium test physics to try in in addition to investigating "the control change to measure a method", also investigated "the etc.'s effect act for a method", such as the function is in two dint on the object of function effect can from a function of dint to act for;The string merges electric circuit in, the relation between total electric resistance and each electric resistance etc..
(2)The solid example that is in the teaching material analysis.(include each kind of illustration, living and relevant science and technology develop of solid example etc.)
(3)The principle of various experiment, study a method, process.
(4)Related physics history.
Many students are devoted to a bitterness to do exercises in review face pass the distance and neglected the most basic of, the most necessary work-reading teaching material, being enter higher school to pass examination to result in shouldn't have of lose cent but too late to regret.
Two, sorting knowledge contents, categorize to control
Medium test physics to try the each knowledge point in book to overlay a rate higher, is all about 80%-90% for the last few yearses, but to ten point knowledge order of overlay a rate then is 100%.These ten point knowledge BE:the specific heat permit with calories of calculation, light of the glint laws peace noodles mirror become be like a characteristics, buoyancy, Mu laws in Europe, string the characteristics which merge electric circuit, electricity power, the concept of dint, density, press strong, two dint balance.The noodles that the physical knowledge involve is very wide, basic concept, the theories is also a body now different content of course in.The student wants to each the knowledge in the part, carry on categorize according to the knowledge structure, tidy up, become the contact of of each knowledge point, and expand into knowledge noodles, attain basic concept firm control, the basic theories contacts mutually, such as:at the time of carrying on review to speed's this knowledge, can get the thought method of this physical concept to the research to move density, press strong, power, the specific heat permits to go in the formation process of wait other physical concepts, draw inference from one example, then want to attain "the book more reads more thick(knowledge contents many)- the book more reads more thin(generalize a sorting, summary)- knowledge more and more abundant", so then can be quick-witted while examine, with proficiency.
Three, the type categorize and control a method
We have already done a great deal of practice and simulated test currently, the classmates should carry on the analysis to each kind of type in the practice do, compare, categorize, discover among them of the different and similar order and control a problem-solving method.Only controled a method, then can while resolve problem many angle geography solution idea, open widely problem-solving way of thinking and method, then can well develop own ability in the examination.
Four, strengthen the training of ability of the experiment research
The physics takes experiment as a basal academics, new of reform in education in a little bit more very important be the development which pays attention to a student to study ability.Teaching material with win an examination through the years in all pay attention to very to test investigate of research ability to the student.Several near in the last yearses, win a cent that test the experiment in the physics' investigate to be worth in the ascension, but from try a contents up see, already from pure of the memory type model which inclines to an experiment an investigation a design.Recent years of medium test an experiment in, usually investigate a student a design experiment a form, according to experiment device and observe of the phenomenon fill in related experiment data etc. to test basic ability.But this aspect is exactly everyone weaker aspect, lose through the years separately more.Therefore, the classmates want to strengthen training in review.Generally in the experiment the research, everyone particularly wants to notice to provide in the topic of information, the purpose of the explicit research, experiment principle, experiment device of function and choice, experiment operation step, to experiment phenomenon of observation analysis and to experiment the analysis of result induce.
Five, pay attention to a little bit hot problem, confidence examination dynamic state
The last few years of medium test to have hot five major typeses to order a problem in the physics:(1)estimate, estimate to mainly involve a student real life in and the knowledge directly related actual case learn. (2)Dynamic state, break down analysis, investigated a student to break down causal analysis (3)to the electric circuit;the science method mainly investigates physical concept, the thought method (4)in the regulation formation;scene information provides a more scene information in the subject of examination, request according to the topic and sieve an useful and related information from it. (5)Open sex's trying can have another angle in the research, in many ways carry on the method of research, the means can be varied, there is no fixed mode and settle power, the result for study isn't unique and express of the form can enrich colorful.
In fine, is review to face to pass examination, the classmates must attain: review completely cautiously, the knowledge orders noodles to combine and hold a point is a little bit hot, the concept is firm to control and the method use flexibly.
