The world is undergoing major development, major changes and major adjustments. World multi-polarization and economic globalization, technological advances, increasingly fierce competition for talent. People are very well aware that, whether it is economic development, social progress and cultural construction or, in the final analysis is the talent competition. The Chinese exam-oriented education in basic education has a long history and tradition, in order to test scores and blindly carry out the "sea tactical", only concerned with the number of questions the students do not pay attention to the cultivation of students’ ability to learn, causing students to "listen to understand, one to do wrong","talk of a class of problems, will not do a question, "the status quo solve chemical problems obstacles still uncommon. Research on high school chemistry problem solving disorders diagnosis and counseling is based on the analysis of the typical problems in basic education, and this issue will be speculation and empirical research on this theory the following aspects.Introduction. First describes the background of this research, and theoretical and practical aspects of the significance of the research carried out detailed discussion; then, in order to clarify the content and scope of the study, the core concept emerged from the study (eg:Issues and problem solving chemical problem solving, problem solving obstacles, chemistry problem solving disorders, diagnosis, etc.) were clearly defined; checking a large number of documents and books basis, according to the definition of core concepts and content of the study, the research status quo at home and abroad were relatively detailed and comprehensive Commentary; Finally, the research framework of this study, such as research ideas, research methods and innovation research.Chapter One. Sorting out theories of problem solving. This chapter is a follow-up to carry out the high school chemistry class computing problem solving theoretical foundation and conditions for obstacles diagnostic support. First of all, according to research from the theoretical problem solving theoretical obstacles diagnosis were introduced in detail; then, introduced seven classic models to solve the problem of psychological mechanism and scope of its main ideas, aimed from a psychological causes perspective stoichiometric problem solving class barriers were deep dissection; and finally, in the relevant classical theory and the classical problem-solving model on the basis of psychological mechanisms, for high school chemistry learning characteristics, proposed a "high school chemistry class computing problem solve psychological mechanism model "process.Chapter Two. Analysis and construction of the high school chemistry calculation problem analysis and ability standard. This part is the deep analysis of the problems of stoichiometric. The first section analyzes the nature of the stoichiometric first class of problems, namely the "essence stoichiometric class of problems is actually a mathematical problem of chemical process"; then explains the characteristics (conceptual, integration of stoichiometric kind of problem, a comprehensive flexibility, methods, normative and diversity). The second section describes the different angles from dividing method and solution summary stoichiometric kind of problem. In the third section, on the basis of summarizing the essence of the structure of the process and the activities of the previous research on the problem-solving ability, the characteristics of chemical disciplines, we build a "model diagram stoichiometric kind of problem parsing activities"; then clear stoichiometric kind of problem-solving ability of the constituent elements (chemical knowledge, chemical skills); and finally in reference to the many levels of ability construction method based on the construction of the "stoichiometric kind of problem solving ability level," and elaboration of the "stoichiometric category problem-solving ability level description, "building these theoretical tools for empirical research provides a theoretical basis behind and empirical material.Chapter Three. The development of the diagnostic tools in high school chemistry class on the obstacles of computing problem solving. This section is one of the key chapters of this study, which were developed to solve the obstacles diagnostic tools from a theoretical basis, high school chemistry class computing problem; 2, high school chemistry class computing problem solving obstacles diagnostic tool developed by the development program; 3, high school chemistry three aspects of design computing class problem-solving obstacles diagnostic tool project introduces high school chemistry class computing problem solving barriers develop diagnostic tools. In this study, mainly in chemistry teaching diagnostics and cognitive theory as the core of the theoretical basis of diagnostic tool development, learning advanced framework based on design and development of this research development program. Specified under Chapter II, "stoichiometric class problem-solving ability level description" prepared the "high school chemistry class computing problem-solving obstacles diagnostic test volume", the diagnostic test volume test measured after three rounds, with SPSS17.0 for Each test measurement data collected for analysis, processing, quality inspection tools. After three tests, the tool is in line with the requirements of large-scale test, with reasonable reliability, validity, difficulty and discrimination. We use chemistry teaching diagnostics based on this principle, and the design of the "high school chemistry class computing problem-solving obstacles diagnostic test volume-Analysis volume", combined with "high school chemistry class computing problem-solving obstacles diagnostic test volume" put together to large-scale tests, aimed at multi-angle, deep, all-round student Obstacles explore the reasons.Chapter Four. Empirical research on the disorder diagnosis of the computing problem solving in high school chemistry class. This part is the key section of the study; this chapter will include four parts. First part:definition of good chemical calculations kind of problem solving dimension obstacle diagnosis. Diagnosis will be five levels of the hierarchy as "longitude", five kinds of obstacles type (moderation disorders, thought disorders, intellectual disorders, psychological disorders, and arithmetic disorder) as "dimension", respectively, in different grades, different gender, and different academic level of high school students to carry out diagnostic tests. This section describes the five kinds of obstacles is the type of features, performance. The second and third part is an analysis of diagnostic methods introduced and diagnostic tools. Before using the development of diagnostic tools applied to large-scale diagnostic tests to the obtained test results and data further validate the stability and reliability of the diagnostic tool. The fourth part is the empirical research results are presented. Through further analysis of the data showed that the type of high school chemistry class computing problem solving obstacles, because there are differences in grade differences and academic level, and gender differences are not significant.Chapter Five. The redress of the obstacles of the stoichiometric problem solving in high school class. For high school students raised stoichiometric problem solving class five types of barriers: moderation disorders, thought disorders, intellectual disorders, psychological disorders, and arithmetic disorders, this study presents 23 corrective measures,65 correct strategy, and were given a specific correction cases.Chapter Six. Conclusion. This part is an overall summary and induction studies presented conclusions of this study:1, high school chemistry class computing problem-solving ability is generally not high; 2, high school chemistry class computing complex problem solving obstacles genesis; 3, high school chemistry class computing can solve the problem can be diagnosed disorders correction. Prospects for future research in part, proposed high school chemistry class computing disorder diagnostic problem solving future research efforts in three directions:first, high school chemistry class computing problem solving psychological causes of Obstacles needs further; second, high school An Empirical Study of Health stoichiometric kind of problem solving pending further obstacles corrected; third, high school chemistry class computing problem solving pending further disorder diagnosis.In this study, the level of the problem solving ability is the foundation, systematically explored at different levels of computing capability, different grades, different gender, different levels of academic high school chemistry class computing problem-solving type of obstacles and its causes, and to propose the corresponding corrective strategy, not only for our high school chemistry class computing to solve current problems have a general understanding of the status quo, but also for the majority of teachers for effective teaching provides a theoretical support and practical significance. However, the research is still at the exploratory stage, the use of empirical design, data sampling theory, methods analysis, interpretation of results and other methods there is still a lot of shortcomings, which still needs further in-depth exploration.
