The Application Of Mathematical Chart In Biology Teaching Of Junior Middle School

With the promulgation of "core quality of Chinese students' development" and "biology curriculum standard of general high school",the cultivation of scientific thinking has been paid more and more attention.In biology teaching,mathematical chart is one of the common ways to examine scientific thinking.In the research at home and abroad,the teaching of mathematical chart mainly focuses on the problem-solving skills of senior high school mathematical chart.In junior high school,there is little research on the application of mathematical chart in biology teaching and the cultivation of students' scientific thinking.Although the mathematics problems encountered in junior high school biology teaching are not complicated,but the application of mathematics chart in teaching and teaching evaluation is increasing.Therefore,this paper analyzes the mathematics chart in junior high school biology teaching and evaluation,summarizes the teaching strategies of mathematics chart,and discusses the educational value of junior high school biology mathematics chart teaching.First of all,through the method of literature review,this paper summarizes the research progress of mathematical charts at home and abroad,and puts forward the research questions: how to excavate the content of mathematical charts in junior high school biology teaching,how to construct effective teaching strategies to highlight the educational value of biological mathematical charts? At the same time,it analyzes the current three editions of biology textbook in Shandong Province,"the topic of people in biosphere" and the content of mathematical charts in the test questions of junior middle school's academic level in biology in Shandong Province in recent three years,analyzes and summarizes the presentation methods and characteristics of mathematical charts in the textbook and teaching evaluation;then,according to the current situation of investigation,the cognitive level of junior middle school students,the content of the textbook,aiming at the current preliminary stage From the perspective of cognitive law,this paper puts forward the teaching strategy of cultivating scientific thinking in mathematical chart teaching of Chinese biology.Then,through interviews,classroom observation,and test paper analysis,it verifies the effectiveness of the teaching strategy.Finally,it looks forward to the implementation object,practice time,teaching evaluation and other aspects of this study.Through the above research,the following conclusions are drawn: the types of mathematical charts in junior high school biology mainly include digital tables,coordinate charts and a small number of percentage rate charts,which can improve students' thinking ability of chart conversion,chart conversion,analysis and reasoning in teaching;the teaching and learning process of mathematical charts in junior high school biology is good as a whole,and students' ability to identify and analyze charts needs to be strengthened The teaching content also needs to be excavated according to the learning situation and the teaching ability of the teachers;the effective strategies of mathematical chart discrimination are: understanding mathematical chart?interpreting the content of the elements?analyzing the data description?summarizing the biological significance;the effective strategies of mathematical chart drawing are:making clear the connection between the contents of drawing?designing mathematical chart?drawing and checking mathematical chart?discriminating mathematical chart;mathematical chart The use of table teaching strategy can improve students' ability of scientific thinking such as induction,reasoning,criticism and creativity.
