| Chemistry is a science based on experiment which occupies an importantposition in chemistry teaching. The progress of the chemical teachingexperiment directly affects the quality and effects of school’s chemistryteaching. In2011, the Ministry of Education amended chemistry curriculumstandard of compulsory education(hereinafter called"2011version of thecourse standard"), which pay more attention to the chemistry experimentteaching of junior high school. At the same time, higher requirements were putforward in the chemistry teaching from all sides. To understand the presentteaching situation of the chemical experiment in junior high school after thestandard revised in Guizhou province, the author made literature analysis,questionnaire investigations, interviews and other research methods for anin-depth investigation of the current teaching situation of junior high schoolchemistry experiment. Research content includes: comparison of the oldchemistry textbook with the new one to study the changes of the experimentalcontents, study of teachers’ adaptability to the new revised curriculumstandard, and comparative study of the present chemical experiment teachingsituation in urban and rural junior high school. Based on the above researches,conclusions got as follows:(1) The analysis and comparison of the experiment contents between theold and the new chemical textbook (take PEP edition as example) tells littlechange in the number of the experiment contents, but great changes in experiment design and experiment content arrangement. The main changes ofthe new textbook are: it reduces the requirement of the students’ experimentalskill, increases eight activity experiments; and concerns more about the safetyof the chemistry experiment and environmental protection; the verbaldescription is more simple and clear, experiment content based on theexperience of students and pay attention to the contact with students’ dailylife.(2)Study of teachers’ adaptability to the new revised curriculum standard:after training and learning, most of the teachers had a certain understanding ofthe2011version of the course standard.78.5%of the teachers agreed with the2011version of the course standard, while21.5%of remained neutral. Thedepth and breadth of the teachers’ understanding of the2011version of thecourse standard is not enough, there are significant differences onunderstanding between the urban and rural teachers.93.5%of the junior highschool chemistry teachers participated in the training of the2011version ofthe course standard, but the training was mainly in county district and citystate, rural teachers rarely participated in training of above the provincial level.Most of the teachers involved in the learning research activity of the coursestandard, but the participation proportion of urban teachers is much higherthan rural teachers.(3) The research of teachers’ understanding and attitude to the experiment:most teachers’ understanding of the experiment function are comprehensive, but the curriculum concept is not thorough, the satisfaction of the currentchemistry experiment teaching is low,17.9%of the teachers choosesatisfaction, while56.33%of the teachers choose general,22.27%are notsatisfied, teachers’ understanding of the experiment between urban and ruralschool has significant difference.(4) The conditions of school’s chemical experiment: all schools have adedicated laboratory, and the number of laboratory basically reach thestandard, hardware facilities can basically meet the needs of students’experimental activities, school equipped with modern experimental teachingequipment is less, experimental apparatus and medicines only partially satisfythe teaching, schools lack of chemical full-time laboratory technician,equipments and preparations of laboratory are relatively weak, experimentalteaching conditions of urban and rural has differences significant, the villagesand towns school’s experimental conditions much worse than urban school.(5) Situation of carrying out chemical experiment: The inquiryexperiments done less, the rate of carrying out demonstration experiments andstudent experiments is low. Fewer teachers guide students to extracurricularexperiments, teacher lack of discussion and exchange with students forextracurricular experiments. Overall, situation of carrying out chemicalexperiment of urban and rural middle school has significant differences; urbanmiddle school is higher than the villages and towns middle school for rate ofcarrying out experiment. (6) Situation of questionnaires of student: The majority of studentsinterested in chemistry experiment, students think chemical experiment is agreat help to chemistry learning, students are also very willing to do chemistryexperiment, and most of the students are willing to act as the main operators inthe experimental process. The students’ experiment was carried out in mostschools. Schools’ experimental apparatus can meet needs of teaching, but thelaboratory open frequency is very low, few students can accomplish chemicalexperiment independently. In the evaluation of student achievement, moststudents prefer to examine the students’ ability of experiment operation, ratherthan a reference to the lab report. Economically developed areas comparedwith the backward areas, it is better in economically developed areas thanbackward areas that attitude of students on experiment, how much proportionof student experiments, situation of students complete experimentsindependently, experimental conditions. |
