Investigation And Research On The Present Situation Of Chemistry Experiment Teaching In Ordinary Middle School

Chemistry is a subject which is based on experiments, and it is a highly applicable science. Students learn the chemistry basic knowledge and skills by doing the experiments, improve their scientific literacy. With the new curriculum reform, chemistry experiment status, highlighting the importance of chemical experimental teaching. However, in the teaching of chemical experiments in practical, because of the influence of various factors, there are still some problems in common in the current chemistry experiment teaching in middle schools.In order to understand the status of chemistry experiment teaching in a ordinary middle school of a district, Dalian first,we tease the information both here an abroad, drawing the advanced theory and experience of experiment teaching, and then we conducted a questionnaire survey from "experimental teaching conditions", "experimental teaching implementation situation", "the effect of experimental teaching situation", "experimental teaching evaluation the situation", "experimental teaching in Teachers’ training".Through the investigation and study, the problems of implementation of the current chemistry experiment teaching of junior middle school: 1, the lack of security mechanism: the experimental class is not guaranteed; the blank of professional experiment of post system; the low rate of using the labs, the lack of supervision. 2, the chemical experimental teaching implementation is not ideal: the teacher’s understanding and the actual teaching conflict; the experimental contents are dull, the lack of interest; experiment rate is not up to the standard requirements; the experimental innovation ability is weak; the lack of measure in treating waste liquid and waste residue. 3, the chemical experiment teaching effect is not obvious. 4, the chemical experimental teaching evaluation is not perfect: the school evaluation system and quality education conflict with each other; the training of teachers only pay attention to the evaluation results of single evaluation method. 5, the experimental teaching of chemistry teachers is not perfect: the training content is not determined according to need; lack of training assessment system.Through in-depth, detailed analysis of the causes of the problem, we finally put forward the solution to the problems, and they are as follow.1, the soundness of the new curriculum chemistry experiment teaching security system: the chemistry curriculum reform to ensure adequate preparation, chemical experiment class; establishing the post of junior high school chemistry laboratory technician Laboratory Technician full-time, strengthen the team construction; making chemical laboratory supervision system. 2, to ensure the effective implementation of Chemistry Experiment Teaching: the transformation of Chemistry Teachers’ ideas and improve their cognition; improve the school-based curriculum, to promote the reform of chemistry experiment teaching content; increase in laboratory efforts; to carry out self created teaching design, innovation experiment teaching aid competition; to enhance awareness of environmental protection.3, make full use of the curriculum resources of experimental teaching to improve the teaching effectiveness.4, improve the evaluation mechanism of chemical experiment teaching: changing experimental teaching evaluation concept; the establishment of teacher evaluation supervision system; choose the diversification of evaluation; 5, improve the training of experimental teaching of chemistry teachers: the training content and determined according to the needs of teachers; charge teacher training appraisal system in teacher training.
