1、1Improve the efficiency of the study of chemistry on the application of science read back,Summary: Read the back is the traditional language learning methods. Reading back the role is to strengthen knowledge and understanding, so as to achieve the purpose of memory is used to visualize the oral, it
2、is also an important way of teaching, also can be used science teaching to improve classroom efficiency. Keywords: science, reading back interest in learning learning efficiency The current the New Curriculum surging, teachers are constantly teaching education reform in order to adapt to changing st
3、udents, and gradually shift constantly by the examination-oriented education to quality education. The new chemistry curriculum standards requirements: high school chemistry should master the content mastery knowledge unifying finishing, so that network and orderly storage, correct retelling of repr
4、oduction, the ability to identify. “The science read back on allows students to repeat and reproduction of knowledge. 2Why read back Many people think that the only liberal arts need to read the back, while science just need to understand it is not true, the science of learning also need to remember
5、 a lot of knowledge and digestion, for some of the more difficult to understand the theorems and conclusions, as well as common sense knowledge can be applied to Reading back. forefathers said, “the chance to read a hundred times and its meaning from the see. reading liberal arts content, focused on
6、 between the lines can ferret out meaning and thinking, studying science content, the focus is to sort out the authors ideas, see how specific methods to solve the problems encountered in the actual chemistry is a set number of concept, chemical reactions and phenomena, rules and disciplines, has be
7、en hailed as a science in the liberal arts, thus the chemical disciplines read back the role of the more obvious. My school as a rural middle school students based on generally poor, a considerable part of the students are not able to complete the normal classroom performance doze off for class, not
8、 paying attention in class, play phone, 3reading magazines discipline endless stream, the majority of learning in a passive response status, lack of initiative, and lectures with a negative attitude, lack of independent learning habits. study found that students with learning difficulties, poor acad
9、emic performance of students, often due to learning efficiency is not high, more and more knowledge barriers reached the point of irreparable memory defects are often one of the main causes students with learning disabilities in this case, there is an urgent need to find a way, you can reduce the el
10、evation to increase students interest, so that the students into learning among science read back to find another way of learning so that students from a single tedious problem solving, so that part of the basis of the relatively poor can not answer the students find learning method to avoid the “no
11、thing to do” in science learning! Second, what to read 1, read the textbook The textbook is the best reference book is the best supplementary information, good use of teaching materials is the only way to lay the foundation for teaching materials are not familiar with how to be able to speak to the
12、mastery of knowledge, how knowledge serialized network 4so into their own thing for textbooks can read the following: (1 Reading Textbooks concluding statement and conceptual statement (2) Reading Textbooks demonstration experiments and student experiments. (3 Reading textbooks “reading material” an
13、d “research study” and “family small experimental materials read back, you can let the students textbook good understanding, reach the realm of reach” Xinshou Pinch to use. 2, the read target The learning objectives of a lesson students learn the need to complete the task, but also the direction of
14、student learning reading goals, students can make the students to clear the content of the lesson and heavy and difficult to do “a pretty good idea.” Class followed by target last self-evaluation by the control target of the class, “What have I learned? I did not get to know what knowledge?” 3, read
15、 focus Focus on knowledge students need to focus on the academic level exams often test centers, and thus to give every student are “obvious”, repeatedly chewing and 5appreciate. Example, the principle of chemical equilibrium mobile learning, students Lexia the special principle “If you change a con
16、dition affecting the chemical balance, the balance will be able to weaken this change direction,” Although this principle only thirty words, but many students can not really understand, we need to let the students continue reinforce this principle is to let the students read back, and at the same time strengthen the memory, so that it can break through the difficulty. 4, read the questions For poor students based on their reading time easy to seize half Start, proble
