Experimental Research On The Chemistry Conception Constructive Learning In Senior Middle School

Chemistry conceptions are basic requires in founding and establishing this discipline. They are also the main contents for Senior Middle School Chemistry studying. Concerning the students' studying, it is a crucial approach to acquire knowledge by getting a whole understanding of conceptions, the mastery of which would also of stepping-stone significance to develop their capabilities and skills. Taken all above-mentioned into account, we can therefore easily conclude that the studying and mastering of conceptions are one of the priorities and goals which students must target at the very beginning, and which would to a degree exert great influence on their promotion in terms of grades and learning ability in this discipline, thus the teaching and learning process of Chemistry conceptions has been all the time held as hot and influential. The extant research of such are mainly focused on theatrical aspect and empirical introduction, while teaching probe into constructing Senior Middle School Chemistry conceptions is still rare.This dissertation emphasizes on the acquiring and teaching of secondary school. Chemistry conceptions which from an ideal point of view, advocates student's constructing conception in an active attitude, thus realizing meaning construction of the conception; and which in terms of teaching methods, chooses the conformity, studying means out of the constructism, learning theory to construct the basic process of teaching syllabus. In this tendency converting the once teachers' defining into student's definitions with the guidance of teachers, thus achieving the once teachers' defining in student's quick, accurate and voluntary conception meaning construction. The research sampled for two classes of Grade 1 in Xinhua No.5 Middle School is thus selected in this research. While optimized teaching syllabus and ideas are involved in the sample class, regular teaching methods are exerted, in the comparison class. Select by examinations 1 in height of 4 concepts carry on a teaching contrast experiment, interviewing and so on to investigate a student after adopting the observation, lesson of the quiz, teaching, adopting SPSS 11.5 analysis the software handle concerning the data.The results indicate:(1)It is beneficial to the students' optimization of native structure, their quick and accurate constructing conception, their promotion of Chemistry grades and their development of all-round abilities.If starting out on the basis of the students' own possessing cognitive structure, according to the studying attributes of the conception; and analyzing specific teaching conditions, thus designing a teaching syllabus. which is advantageous to their quick and accurate meaning constructing.(2)Provided that students' group work of schoolwork is the prerequisite of when making a teaching syllabus, different teaching methods should be adopted to students of different levels. In this teaching experiment taken, there are certain disparities of the results among the students of different levels both in the sample class and comparison class. The teaching syllabus thought and teaching ideas in my essay benefits the chemistry studying of those students with above-average groundwork for chemistry while it does not benefit that of those with an unfavorable foundation for chemistry.
