| Generating of students with learning difficulties maybe bring irreversible impacts on the process of growth and taught of students. Namely its existence would affect the further learning and development of students. And it manifested in the follow fields Mainly:pursuing the process and result of their goals in life; forming personality and it’s moral; basic abilities and responsibility to adapt to social life, by which might be affected.For the moment, according to the general features the high school performance of poor students can illustrate that the chemical students with learning difficulties, is a common.And it is likely to become hinder of forming an effective teaching model and in aims of Quality Education in the present and within coming for a long time. Therefore, it is issue within common value that a chemistry teacher must face to.In this paper, with the theory of pedagogy and combining features of chemistry, is to investigate the characteristics of the students with learning difficulties, learning differences with eugenics, effective transforming strategies by organic combination of theoretical research and teaching practices.The researh starts with investigation of high school students with learning difficulties, about the formation process and the basic performance characteristics of objects deeply; analyses the factors that may affect generation and have a relevance analysis to the further data; finally, according to the analysis of the above, is to control, prevent and transform in teaching practice. It provides the theoretical guidance and specific practices for inexperienced teachers scientifically with a reference, also for self-adjustment of poor students has made specific requirements and means.This paper is based on the theory of empirical research, which is from practice to theory and then back to practice in research process.Research emphasis of this paper is not only investigation on the status and generation of the chemical learning difficulties, but also to be concerned about the conversion and differences between poor students and eugenics; not only committed to theoretical studies of chemical learning difficulties, but also to be concerned about the empirical study on the process of education; not taken into account the current development of students in the abilities, and more emphasis on the quality with enhancing.Small-scale (involved in three direct teaching classes of high grade) teaching is a feature of this paper, that not only to be targeted, also to ensure the effectiveness of controlled factor to produce results. The research findings provide effective references for teaching practice. |
