A Research On Junior School Students' Thinking Obstacles In Solving Scientific Enquiry Questions

In the tests of junior schools' chemistry learning,scientific enquiry is a common type of question,not only is it important content of Suzhou high school entrance examination,but also a kind of question of common concern.In the process of learning and solving scientific enquiry questions,students can gradually develop their own scientific thinking ability,as well as the abilities to analyze problems and solve problems.During the study of scientific enquiry questions,studentsnot only need to fully grasp the basic knowledge,comprehensive understanding and application of chemical concepts and principles of the process,but also need to master the basic experimental skills,instead of simple knowledge answer.At present,scientific enquiry is one of the most important and difficult points in junior high school chemistry study.However,students often feel helpless when faced with scientific inquiry problems,and it easily leads to thinking disorder.In this paper,on the basis of the study,the research and scientific theory,to solve the problem of thinking obstacles explore the obstacles of problem solving combined,compiled questionnaire for junior high school students scientific enquiry learning problem,in a middle school in Jiangsu 93 middle school students as the research object were investigated,and according to the investigation of the 4 questions in the process of solving scientific enquiry often mistakes students conducted a semi open interview.According to the data,and the data of questionnaire statistics,a junior high school students in solving thinking obstacles of scientific enquiry questions are: affective disorder,dyslexia,knowledge extraction disorder,goal barriers,obstacles,strategic thinking,reflection and evaluation disorder;causes of these obstacles are: knowledge system is not complete,thinking the negative influence of lack of problem-solving strategies and lack of confidence in learning.According to the research results,this study puts forward some teaching suggestions to help students reduce or eliminate these obstacles: using mind map to help students improve the knowledge structure,solve scientific experiments to explore the topic of general policy guidance,the learning of scientific enquiry interest in improving the creation of conditions.Due to the limitations of time and the progress of teaching and other reasons,the type of scientific enquiry questions did not discuss analysis and comprehensive study,causes the student in whether there are other reasons to solve thinking obstacles of scientific enquiry questions,need further improvement in the teaching and research in the future.
