Improvement Of Junior High School Biology Experiments

Biology is a laboratory-based natural sciences, experiment is an important part of biology teaching,it plays a vital role in biology learning. With the advancement of basic education curriculum reform, experiment in biology teaching position gradually improved.In order to carry out experiments more smoothly,improve biological experiments is necessary.Therefore,the practice to improve Junior high school biology experiment has important significance,not only can help teachers, but also cultivate students hands-on ability,the ability to explore and innovation ability.In this study, use literature search,observation,text analysis,investigation and statistics for junior high school biology teachers,in order to investigate and analyze current situation for experiments set up and improve,to understand the current status of biological experiments set up and improve,carry on case studies for experiments improve,propose experiments recommendations for improvement and can help teachers.First of all, get the preliminary conclusions by questionnaire surveys and interviews as follows:First,schools,teachers and students are very supportive of the creation of biological experiments that it is necessary to set up the experiments;Town and urban schools,teachers,students have no significant difference about the experiment.Although the schools,teachers and students can be aware of the importance of the experimental opened,but biology textbook experimental opening rate is not high,only little experiments can be really opened.Second,most teachers believe textbook experiments is enough to meet the students’ learning, but in fact the biology textbook experiments open rate is not very satisfactory;The reasons are not readily available experimental materials,complex experimental device,mechanical experimental methods,the experiment takes long and trouble and so on.Therefore, to improve the experiment is very necessary.Third, about the attitude,Students hold a positive attitude to improve the experiment,but schools and teachers is not positive to improve biological experiments;the teachers in township school and urban school have significant difference about the experiment.Fourth,Students hold a positive attitude to improve the experiment mainly performance in enjoying the experiment and are willing to cooperate with teachers in improving experiments;Although the school can provide some hardware and a certain amount of funds,but lack of training about improving the biological experiments;Teachers’ attitudes towards experimental improvement is not active and very little to improve the experiment,the reason have subjective factors(the attitude of the teachers and their own quality etc.) and objective factors(the experimental training,evaluation system,limited time etc.).Then, analyze experimental part of Jinan Press "Compulsory biology textbook"(including the seventh grade Book 1 and Book 2,eighth grade Book 1 and Book 2). On this basis,carried on the improvement of the experiment and show case from the material,experiment device,experiment method,experimental conditions,experimental sites,the experiment project and supplementary that seven aspects to provide a reference for teachers.Finally,on the basis of investigation,put forward suggestions to experiments improve for schools and the teachers.For schools:(1)Hands-on training:Schools should support experiments to improve,to provide teachers with hands-on training;(2)System:Schools should scientific evaluation,establish the evaluation system to experimental improvement;(3)Time:Schools should rational allocation time,to provide teachers with time to improve the experiment.For Teachers:(1)Concept:Teachers should change their ideas,improve awareness to experiments improve;(2)Quality: Teachers should enhance the innovation ability,promote improvement of the experiments;(3)Teaching Behavior:Promote experiments improve according to local conditions.
