| "National long-term education reform and development plan (2010-2020)" pointed out China’s educational concept has long been relatively backward, the content and method are outmoded, students’abilities to adapt to society and employment are not so strong, there are lack of personnel with creativity, practicality and multi-ability ". Education reform should focus on ability, especially on improving students’study ability, praising ability and creating ability and should overcome the tendency of examination-oriented education. But nowadays, this tendency of high school chemistry trenching is still very serious, mainly reflected in that chemistry teaching deviates the feature of "laboratory-based" in this subject. Experiment doesn’t play an important role in chemistry teaching. Experiment course are not paid enough attention to in senior one and two, experimental class sometimes is a mere formality, or even a jerry-building. When in senior3, busy in preparing for the college entrance examination, students hardly have the chance to be in the laboratory.In fact, in recent years, the college entrance examination strengthens examine students’ ability, only those with enough experiment experience can get high marks. Therefore, we choose the project of analysis the capability structure of senior threes’chemistry experiment and the study of training strategies, trying to offer an example to solve the problems above through study.The thesis has mainly taken the research methods of literature analysis, investigation and teaching experimental study. From the educational function of the chemical experiments, chemical experiments to construct knowledge autonomy of theory, practical chemical experiments skills acquisition theory, recent theories of the development area can be observed learning outcomes structure theory perspective, we first use SOLO method,sorting experiment ability structure in the college entrance examination into five levels of memorizing, understanding, synthesis, application and innovation. Secondly,design measurement problems, investigated the level of the students of the school where I am teaching; then constructed experimental reading instruction, the experimental scene experience to redo the classic experiments, in fact, do create their own experiments and other teaching strategies, and used them in the third year chemical review teaching. We found that the students’experiment capability structure is mostly in " memorizing " and "understanding" before the teaching intervention, the correct rate on test questions is0.323, after a period of time’s teaching intervention, students’correct response rate on the test questions was raised to0.464, the score in a single point of the structure, multi-point structure and the associated hierarchy of ability increased significantly; ability levels of expanding structure and abstract structure did not change significantly. The average score in experiment has improved significantly compared with those tested before. Students overall results increasing showed a significant positive connection with the experiment scores increasing, besides, students’attitude, achievement motivation significantly has also improved, the situational experiment greatly enhance students’the experimental reading ability and interest in exploring; Redoing classic experiments and performing the experiment created by themselves enhance the depth of understanding and application of knowledge; SOLO analysis will help us to guide students to sorting complex and lengthy experiment into a number of simple ones, then solve them step by step, in this way those students whose study is not so good can get some scores instead of being afraid of the questions.. However, this method shows little effect on excellent students.Through research, I enhance the academic ability to explore and teaching, however, because of the level and time constraints, many of the problems found in the research process, need to be further explored in my future research and practice. |
