| " The ordinary high school chemistry curriculum standard (test)" promulgated in 2003 explicitly requests that the student can solve chemical problem through discovering and asking questions from exercises, and by other forms such as interviewing and visiting, investigating and testing. But in the usual teaching process, many first-line teachers often screen exercises from the internet or subscription material, they even use the full range of the original exercises.However, there are lots of mistake and missing exercises in most of the chemistry exercises. some even "numerous, difficult, partial, old", which may disturb the students’ cognitive, hit their enthusiasm of learning chemistry, let alone to find and solve problems. Based on this situation, we chose " the compilation of the senior one chemistry formative exercises as the research subject. By control the number and the difficulty of formative exercises, compile the exercises which are fit for the senior high school students poor in county. At the same time, the student participate in compiling exercises can enhance their interest and confidence in learning chemistry.The study focus on the compilation of chemistry formative exercises for senior one, mainly expounds the following contents:The first part starts with the curriculum standard and the current research of formative exercises’ compilation at home and abroad,expounds the background of this topic’s selection, and explains the purpose, significance, content and method of this research.The second part explains the of the definition of exercises, formative exercises and chemistry formative exercises, analyzes the theoretical basis of formative exercises’ practical research in Senior chemistry, under the guidance of the constructivism learning theory.multiple the intelligent theory, the zone of proximal development theory, cognitive load theory.The third part survey the whole situation of the school, including teachers, students, the use of exercises through the form the questionnaire, which provide the reality basis for the raising of the later research strategies.The fourth part, based on the advanced theory and the author’s teaching experience, summed up the four functions of exercises:diagnose learning difficulties, encourage active learning, enrich knowledge reserve, and promote the function of knowledge transformation and puts forward the four principles of chemistry formative exercises design:the directivity. situational, hierarchy, diversity, and build seven strategies for the chemical formulation of formative exercises; using curriculum standard as a starting point, make sure the formative exercises don’t deviate from the direction; using the situational material as entry point,closely connected with social production and living; using the students personality differences as the growing point. meet the requirements of students in different levels; Students can finish the exercises on time as the foothold, grasp the difficulty of the problem sets and quantity; using the development of new type of exercises as sparkle, widen students’view; by editing the exercises, students their themselves, arouse their interest in learning; using the power producer by teachers’ teamwork, improve the exercises’quality and efficiencyThe fifth part is to test whether the chemical formulation of formative exercises can improve students’ interest and attitude in learning chemistry, can improve students’chemistry academic achievement, we had a 6-month study in grade one of Debao Senior high school by using the methods of questionnaire, investigation, interview and so on, to research whether the formative exercises under the guidance of the proposed strategy can have an active effect on students’ study interest, attitude, grade in chemistry.The sixth part study is the conclusion from experiment:compiling Senior high school’s formative exercises cant significantly enhance the students’interest in chemistry learning; controlling the difficulty and quality can be beneficial to promote the students’confidence of learning chemistry:That students edit exercises by themselves can be helpful to strengthen their cooperation and communication ability; By "edition-a review of the problem-finalized " in the group, improving teachers’ability of scientific research. That is to say, the strategies of Senior high school’s chemistry formative exercises put in this paper is feasible and effective.This research study time is short, the object of study is the ordinary Senior high school at the county, where the student’s basic is poor. So when the strategies of the exercises compilation put forward in this research are carried out in better school,whether they can achieve the same experimental results remains to be further research. |
