| The new curriculum reform in the content, methods, goals, evaluation and other aspects bring profound changes to high school chemistry teaching, implementation of the new curriculum request chemistry teacher shake off the shackles of examination-oriented education, change the "one size fits all" concept of traditional homework. Although the new Curriculum Reform has already implemented, however, many teachers have not yet establish a correct concept of homework, homework as an important part of the process of teaching, is an important issue of curriculum implementation that each teacher can not be ignored and avoided. Therefore, it is necessary conducted theoretical and practical aspects of research for the design and evaluation feedback of chemistry homework, improve the quality of chemistry homework, thereby providing some guidance of homework design and evaluation feedback for the first-line chemistry teacher.Thesis borrow and absorb the advanced educational theory and experience, absorb domestic and foreign teachers to students useful homework experience in the design and evaluation, and shall constructivist learning theory, the theory of multiple intelligences, formative assessment theory introduced among chemistry formability homework design and evaluation feedback, shall the design and evaluation of chemistry homework to construct on the basis of scientific theories. Formability homework design strengthened the practical study of student work, enhanced the relevance, fun, practical and exploratory of homework, and focus on students’individual differences, enhance the levels and optional of homework, to meet the needs of students at different levels. In addition, the thesis also depth study the entire process of the chemistry homework layout, and take full account the nature and characteristics of chemistry subject, offer strong maneuverability, targeted strategies to eleventh grade chemistry teachers for the design and evaluation of homework, while providing a reference paradigm to the practical aspects of chemistry teachers assignments. Thesis includes the following six sections:The first part conduct investigation and analysis and reflection for the status of traditional chemistry homework, under the new course background proposed a new homework design: defined the definition of homework and chemistry formability homework, and described the research purpose, significance and practical value, contents and methods of the thesis.The second part provides a brief overview of this study background and the abroad research status of homework design and evaluation feedback.The third part is borrowed the advanced educational theory and experience-constructivist learning theory, the theory of multiple intelligences, formative assessment theory to guide the design and evaluation feedback of high school chemistry formability homework research. The fourth part based on the advanced theories and teaching experience of the author, proposed four tactics:purpose, stimulated interest, practicality, hierarchy for chemistry formability homework design, and research and development the homework case of chemistry formability homework, show its effectiveness; constructed the hierarchical evaluation, highlights evaluations, multi-directional evaluation, several evaluation etc. new coursework assessment feedback tactics, and studied some of the cases.The fifth part put the research of homework design and evaluation feedback into practice, test chemistry formability homework design and evaluation feedback will help improve students’ interest and attitude in learning chemistry, improve student academic performance in chemistry. Based on the questionnaires and interviews analysis, found using chemistry formability homework design and evaluation feedback tactics in teaching can significantly enhance students’ interest in learning chemistry, change its chemical learning attitude, promote students’chemistry academic performance.The sixth part summarized the conclusions of this study, and carried a reflection and outlook on shortcomings of homework design and evaluation. Designed purpose, fun, practical, hierarchical etc. chemistry formability homework, can significantly enhance the students’interest and attitude in learning chemistry, help students improve their chemistry academic performance, enhance students’practical ability to explore and innovative spirit. Use the hierarchical evaluation, highlights evaluations, multi-directional evaluation, several evaluation etc. assessment feedback tactics, to encourage the main, evaluation highlights, allow students to participate and experience the success, help establish confidence in learning chemistry, especially the students who’s foundation is weak, gain a great harvest in this study. This experimental study, have made a good results in the homework design and evaluation feedback cont study ext. |
