A Research On The Strategy Of Physics Experiment Teaching Research In Junior Middle School

Experimental inquiry is not only the important content in physical teaching and learningstyles, but also the physical teaching goal. The experimental design was in the physicalexperiment teaching is the important part of scientific inquiry, is the important factor.Physics experiment design in the experiment were carried out before, the experimentersaccording to the objectives and requirements of experiments, using the theory and knowledge,for experimental purposes, experimental principle, experimental procedures of experimentscheme. The experimental design including clear experimental purpose, selection ofexperimental principle and experimental design of3parts.In experimental design are based on the preliminary research, put forward the physicalexperimental design should follow6principles: the principle of precise, scientific principles,feasibility principle, foresight principle, simplicity principle and the principle of a singlevariable.From the teaching goal and students present situation2aspects discussed influenceexperimental design teaching strategy choice factors.By using the investigation method, based on the physical experimental design steps,proposed the high school physics experiment design of3teaching strategies: defining theobjective teaching strategy, choice of experimental principle teaching strategies and design theexperiment scheme of teaching strategies, which will determine the objective teaching strategy isclassified as fixed experimental variables and combined with the experimental variablesdetermining experiment the purpose of teaching strategy; will choose the experimental principleteaching strategies are divided into the dependent variable, independent variable observationchanges and observation, the control of experimental conditions, the experimental principle ofoverall design and integration of the4strategy; will develop experiment teaching strategies forexperimental equipment, combined with the initial selection of experiment content selectionexperiment equipment specifications, to determine the experimental procedure, experimentaldesign, combining the experimental form of process improvement experiment scheme5strategy.Each of the teaching strategies are based on the high school physics teaching case study. Application of formulation design of high school physics experiment teaching strategy of"Lenz’s law" and" explore the acceleration and force, quality" two lessons of teaching design,illustrates the application of these teaching methods.
