CHEN Jing ̄anꎬ ZHANG Ran ̄ran(Department of Mathematicsꎬ Guangdong University of Educationꎬ

Guangzhouꎬ Guangdongꎬ 510303ꎬ PRChina)

Abstract The effectiveness of mathematical teaching depends on the effectiveness of pre ̄lecture teachinganalysis and design implemented by mathematical instructors The pivot of how to improve the efficiency of teachingon mathematical concepts lies in the fact that mathematical instructors should keep the three fulcrums describedbelow in balance when making the time ̄consuming preparation of teaching analysis and teaching designꎬ as well asbuilding the understandingꎬ analysis and design from three perspectives precisely rather than inaccurately

Abstract It is necessary to differentiate the relationship of FranckmdashHertz experiment and Bohr theory andpoint out some presence of misunderstanding in famous atomic physics textbook It is believed that Bohr Theoryemits before the FranckmdashHertz experiment in most materialsꎬ but actually it is not so As furnace temperatureincreasesꎬ the probability of collision between electronic and atomic mercury increasesꎬ so the plate currentdecreases The increase of emission voltage brings about the increase of the number of electronic emission and theconstant collision probabilityꎬ so the plate current increases With the increase of the gate voltageꎬ the electroninitial velocity also increasesꎬ the collision probability between the electronic and the mercury atoms in the KGspace is reducedꎬ so the peak of the plate current increases

The Conspicuous Problems in the TeachingPractice of Biology and its Initial Reforms

CHEN Ai ̄kuiꎬ GUAN Jian ̄liuꎬ GUO Kai(Guangdong University of Educationꎬ Guangzhouꎬ Guangdongꎬ 510303ꎬ PRChina)

Abstract Teaching practice is an obligatory course as well as an important research topic in teacher ̄trainingBiology differs from other disciplines in that it has much experimental characteristic These problems can be foundin the teaching practice of biology systematic and effective training is inadequate for the traineeꎻ trainersprime basicskills are not good enoughꎻ experimental courses are few in the schools for teaching practice and practice guide fromhigher education does not show up This paper puts forward some suggestion to improve the teaching practice ofbiologyꎬ hoping to explore its reforms which can guide this disciplineprimes teaching practice and use the experience forsimilar disciplinesprime reference

Key wordsbiologyꎻ teaching practiceꎻ reforms for teaching practice

A Discussion on Franck-Hertz ExperimentLIN Qia ̄wu

(Department of Physicsꎬ Guangdong University of Educationꎬ GuangzhouꎬGuangdongꎬ 510303ꎬ PRChina)

Abstract It is necessary to differentiate the relationship of FranckmdashHertz experiment and Bohr theory andpoint out some presence of misunderstanding in famous atomic physics textbook It is believed that Bohr Theoryemits before the FranckmdashHertz experiment in most materialsꎬ but actually it is not so As furnace temperatureincreasesꎬ the probability of collision between electronic and atomic mercury increasesꎬ so the plate currentdecreases The increase of emission voltage brings about the increase of the number of electronic emission and theconstant collision probabilityꎬ so the plate current increases With the increase of the gate voltageꎬ the electroninitial velocity also increasesꎬ the collision probability between the electronic and the mercury atoms in the KGspace is reducedꎬ so the peak of the plate current increases

Abstract It is necessary to differentiate the relationship of FranckmdashHertz experiment and Bohr theory andpoint out some presence of misunderstanding in famous atomic physics textbook It is believed that Bohr Theoryemits before the FranckmdashHertz experiment in most materialsꎬ but actually it is not so As furnace temperatureincreasesꎬ the probability of collision between electronic and atomic mercury increasesꎬ so the plate currentdecreases The increase of emission voltage brings about the increase of the number of electronic emission and theconstant collision probabilityꎬ so the plate current increases With the increase of the gate voltageꎬ the electroninitial velocity also increasesꎬ the collision probability between the electronic and the mercury atoms in the KGspace is reducedꎬ so the peak of the plate current increases

Abstract It is necessary to differentiate the relationship of FranckmdashHertz experiment and Bohr theory andpoint out some presence of misunderstanding in famous atomic physics textbook It is believed that Bohr Theoryemits before the FranckmdashHertz experiment in most materialsꎬ but actually it is not so As furnace temperatureincreasesꎬ the probability of collision between electronic and atomic mercury increasesꎬ so the plate currentdecreases The increase of emission voltage brings about the increase of the number of electronic emission and theconstant collision probabilityꎬ so the plate current increases With the increase of the gate voltageꎬ the electroninitial velocity also increasesꎬ the collision probability between the electronic and the mercury atoms in the KGspace is reducedꎬ so the peak of the plate current increases
