1High school biology Genetics and Evolution module logic system BriefAbstract: The theoretical system of modern genetics, is a scientific fact as the logical starting point of the axiomatic system. Meanwhile, the genetics of development, evolution for small to provide a logical basis for the study. “Normal high school biology curriculum standards (experimental)” “Genetics and Evolution,” the contents of the module system is built according to logical rules. In genetics and evolutionary process of development, scientists use a variety of scientific methods, scientific understanding of high educational value. The preparation of teaching materials, can be logically leads, but also can be clues to the history of disciplinary development. Thinking abstract thinking and image combination is the module where the value of critical thinking training. 2Keywords: high school biology curriculum; “Genetics and Evolution” module; logic system; small evolutionary Abstract: The theoretical system of modern genetics is axiom system with scientific truth as the logical starting point. At the same time, the development of genetics provide logical basis for the research of small evolution. The content system of hereditary and evolution module in The Biology Curriculum Standards in General Senior Middle Schools (experimental edition) is constructed according to logical regulations. In the developmental courses of genetics and evolutionism, scientists have used many scientific ways which have very high educational values for scientific realization. Teaching materials could be written in accordance with logical lines or with historical lines of subject development, which has its own significance. And the combination of abstract thinking and thinking in images shows the important values of thinking training in this module. 3Keywords: biology in senior middle schools; hereditary and evolution module; logical system; small evolution On the biology curriculum content system structure, the authors had in the “high school biology curriculum construction and the steady-state analysis of the module and the environment,” one paper had been discussed was like, “Genetics and Evolution” module, it can be according to the method of formal logic, identified a number of scientific facts or concepts as a logical starting point, by deductive reasoning to build an axiomatic system. 1 This paper intends to make a specific analysis of this. First, the construction of modern genetics theory Scientific research, must first obtain perceptual knowledge through observation and experimentation. It is through hybridization Mendel pea experiments, gained 4extensive experience in material. However, the perceptual understanding of the material was only a first step in understanding the real task is to achieve rational understanding. This requires a scientific approach to dealing with these materials. How to deal with? First summarizing the material out of these experiences reflected in the nature of things and change the law. This requires scientific abstract. The so-called scientific abstract is that the people to use thinking skills through a variety of things, phenomena, extracting the essence of things and changes in property law of development. Scientific abstract is a complex thought processes. The first step is based on empirical material to form the basis of the concept, that is, from the “emotional on the specific” up to “abstract rules.” The so-called “emotional on the specific” is that the people in the scientific practice in the formation of chaotic appearance; so-called “abstract”, a provision is through a certain way to abstract the essential nature of things. It is from a large number of Mendels pea-specific genetic traits (flowery color, cotyledon is full, plant height, etc.), the abstract “relative character” concept, and further it is divided into “dominant 5character” and the “hidden sexual traits. “ The second step is the application of concepts judgments and reasoning, construction law, principle, that is, from “the abstract states that” up to “thinking in the concrete.” “Thinking in the specific” is different from “emotional on the concrete”, sensuous material is no longer the sum of the facts of the chaos, but rather dominated by certain rules of organized knowledge. Mendel is the dominant traits and recessive traits based on the concepts, summed up the phenomenon of segregation and the free combination. The whole process from the perspective of logic method is a process of inductive reasoning: the premise that a number of scientific facts, the conclusion through reasoning from the premise to be a general law. In the scientific understanding of activities, scientific abstract and logical approach is the same cognitive process in the two sides. On the one hand, understanding the abstract process is a continuous process of the formation of scientific concepts; the other hand, understanding the process is to use a l
