A Research On Explicit Teaching Of High School Biology Tacit Knowledge Based On POE

Tacit knowledge is also called knowing knowledge,Silent knowledge,implicit knowledge.In the field of psychology,the study of tacit knowledge has been deepened,and the educational circles have gradually realized the importance of tacit knowledge to acquire explicit knowledge.But tacit knowledge is indescribable,situational,individual and practical,so how to make use of students' tacit knowledge to achieve knowledge sharing? How to make the implicit knowledge of the students dominant? It has become a hot topic of discussion among all sectors of society and a difficult problem faced by educational scholars.At the same time,a lot of biological knowledge is very abstract and difficult to intuitively describe and touch.It is difficult for middle school students to learn biology;and the hidden knowledge that the students can see is only "the tip of the iceberg".Most of the students' knowledge is recessive,and the students can't express them in words.The explicit knowledge of students can be reviewed,amended or applied to them.It can be seen that it is of great significance to explore how to explicitly expose students' biological tacit knowledge.This paper,based on the previous study of the explicit knowledge of tacit knowledge,uses POE teaching strategy to carry out a practical study on the dominance of high school biological tacit knowledge.First,it introduces the related concepts and theories of POE teaching strategy,tacit knowledge,implicit knowledge dominance and so on.Then,using the POE teaching strategy to carry out specific biology teaching design,and then to make a specific design of biological teaching.It was applied to the class practice.Then,the test was carried out by the questionnaire of the student biological recessive knowledge scale.The questionnaire mainly set six dimensions: the self-cognition and development ability of biological learning,the self-regulation ability in biological learning,the ability of biologic work and the ability of biological activity.Using auxiliary tools to learn biological ability,learning biological self-performance check and self-management ability,finally,collect and analyze the research data.After a semester of POE teaching,the total amount of tacit knowledge in the experimental class is less than that of the control class.It can be said that some implicit knowledge among the students is dominant.After the study of the data,the two dimensions of self-cognition and development ability and self-regulation ability in the biological learning are Sig.<.0.05,in these two dimensions,the effect of POE teaching strategy to promote the dominance of the students' biological tacit knowledge is the most obvious.At the same time,the results of the experimental class students are increasing gradually,and the students' accumulation of learning biology has been significantly increased by the classroom observation.Accordingly,the author draws the following conclusions:First,the POE teaching strategy has a positive impact on improving students' performance.Second,POE teaching strategy has obvious effect in promoting students' self-cognition and development ability in biological learning and self-adjustment ability in biological learning.Third,POE teaching strategy can make the students' tacit knowledge explicit to a certain extent,but it can't be completely explicit.It also needs other teaching methods to assist or explore more effective teaching strategies.In a word,the explicit teaching of high school biological tacit knowledge based on POE has a positive effect on the biology teaching in high school.This strategy helps to promote the progress of students' learning and help the explicit knowledge of the students to be explicit.I hope that the future classroom teaching will pay more attention to the students' tacit knowledge,let the students become the "small prophet" of the exploration of biological knowledge,promote the explicit knowledge of the students,make the personal knowledge amend,consolidate and deepen and share them.
