The Study Of Characteristic Of The Chemical Experiment Evaluation In The Senior Entrance Exam

The new curriculum reform of basic education in China was officially launched in1999, entered the basic education curriculum reform experimental zone since September1,2001, and entered the extension phase in2008. During this period, Ministry of Education has formulated a new curriculum standards, compiled the new textbook, promoted the new teaching way, and also put forward new requirements on the test, However, The Senior Entrance Exam that Widely concerned of students,parents and teachers, whether to meet the requirements of the new curriculum evaluation?This paper takes Pencil and Paper Test and Experimental Operation Test in2009-2011as the Object of study, and analyzes the characteristics of chemical experimental evaluation. The purpose is to reflect the situation of The Senior Entrance Exam, and find the advantages and disadvantages. This paper attempts to answer the following questions:1. What did the chemical experiments of The Senior Entrance Exam focused on? How to test? And what are the weaknesses?2. Pencil and Paper Tests and Experimental Operation whether conform to replace?Firstly, According to the curriculum standards the requirements of the chemical experiments and related research, the chemistry experiment content of the junior middle school is divided into six parts:Basic operations of chemistry experiments, inspection and inference of substances, Separation and purification of substances, preparation-drying and collection of common gas, nature experiments of substances, design and evaluation of experiment. According to these modules, This paper will Investigates and analyzes the contents of the chemistry experiment and the methods of evaluation in Pencil and Paper Tests. Secondly, This paper will Investigates and analyzes implementation, contents and procedure of Experimental Operation Test. Finally, Find out the characteristics of the two exams through comparative analysis.Through the above two research found that:1. Pencil and Paper Test focus on declarative knowledge and productive knowledge, Such as "What"" How to do "and so on; Experimental Operation Test focus on experimental operation skills, Such as "Operation results""habits" and so on.2. The Senior Entrance Exam attaches importance to chemical experiment, and pay attention to the basic chemistry experimental ability and comprehensive ability.3. Experimental Operation Test Consistents with the request of curriculum standard. Focus on the following: Preparation of carbon dioxide;Preparation of oxygen; The nature of the acid, alkali, salt and Simple substance; The use of acid-base indicator; Purification of coarse salt; Neutralization reaction; The preparation of a certain mass fraction of the solution; Identification of substances; The use of the experimental instrument; The access of Chemical; Material heating; Substances dissolved; Determination of PH; The validation of the metal sequence of activities; Law of conservation of mass and so on.4. The chemistry experiment of Senior Entrance Exam still has shortcomings, For example, The grading rules of Experimental Operation Test are not clear; The proportion of Score set unreasonable and so on.According to the research conclusion, The author put forward proposals as follows:1. Further change teachers’concepts and strengthen re-education of teachers;2. Strengthen the management and evaluation of Papers prepared and organization of Senior Entrance Exam;3. Encourage the use of a variety of evaluation methods and give comprehensive feedback of student ability;4. Focused on testing students’learning ability;5. Further clarify the content of curriculum standards;6Strengthen the contact of the chemical experiments and life, stimulate students’interest in exploring;7. Encourage proposition of interdisciplinary, emphasis on the development of science education.
