Middle School Biology Constructivist Learning Environment Construction Research

Constructivism study theory is one kind of new education teaching model, thought that the study is positive and the processing and the explanation which choice the information; The study is construction, is conflict and conformity of the new and old knowledge; The study is the accumulation, by the original knowledge the zero point which grows for new knowledge, carries on the deepening, the breakthrough and surmounting above the zero point.In the construction study, the student is not passively instills into, but in the certain situation, through teacher's guidance, the help and the promotion, in the study community's cooperation, the dialogue exchange initiates the cognition conflict, causes the original cognition structure to change, the assimilation or complied with the current knowledge, completes the knowledge significance to construct the construction.This kind of Constructivism study view to suit the biological discipline study under the new curriculum. Therefore, in biology teaching practice, it is necessary and possible to found the learning environment of constructs the construction principle, guides the student to carry on constructs the construction study, enhances the student biology scientific accomplishment.The construction of Constructivism learning environment in middle school biology is not "constructs the construction principle + biology example", but has the necessity of the biology unique study existence. it regards the learning environment as an education ecosystem, teaching activity and learning activity and the learning environment mutually depends on for existence, mutually unifies, the advancement of teaching and studying and the change of learning environment is the paragenesis coexistence, each advance and passes of the learning process always follow the change of the environment.The design of the construction principle learning environment according to the request of the new class sign in middle school biology and the characteristic of constructs the construction study, follows the life,biological reality, integrity, experimental nature principle and so on, take "study" as the center, enables the learning environment fully to make the student study with the initiative and enthusiasm, promotes independently to construct the construction to the biology knowledge, promotes the developments of inquisition and innovation ability. And moreover, it can make students realize the emotion in the constructing contents. When constructing learning environment, we should fully melts into four essential factors of constructs the construction principle learning environment: the situation, the cooperation, the conversation and the significance construction. We can use the student's experience of life to establish the study situation, establish real question or the real event as the study subject, carry on the independent study, the cooperation study around the subject , constructs significance of the knowledge by oneself, and form the study community, meanwhile in community's exchange and the consultation, deepens understanding and contact between the teachers and students, achieve consensus by reconsidering in the interaction, consequently, students'potential will be stimulated, individuality development will be promoted and the scientific attainment will be improved. To sum up, author constructed the chart about constructs the construction principle learning environment in middle school biology (to see Figure 3 - 1 - 1).In the foundation of design the chart about Constructivism principle learning environment in the biology, the author conduct the education teaching practice research in the Jinan fifth middle school. In the teaching experiment, I take the essential factor of the pattern chart as the dependent variable, take student's biological science accomplishment as the independent variable. We mainly take the academic achievement comparison between front and after measure as the appraisal method. as for the study manner, the learning capability, the scientific accomplishment and so on, which is real recessively, the silence, and difficult to use the marks weight ,then we use literature and data, interview, the record jacket about student grow to carry on the appraisal, and carries on the material statistics, the data analysis and the descript difference characteristic.After a semester experimental study, I has obtained a series of successful experience, for example: The teacher teaching idea transforms, teachers and students enthusiasm, initiative full display; pay attention to the whole of knowledge and turn to the student's life world, promote synthesizing capacity; make the microscopic teaching design turn to the learning environment design, promote process and the result union with actual effect; The instruction and the construction union, the interest stimulation, the joyful study, improve the study quality and so on. Certainly while the study obtains the success experience also encounter some difficulties and questions, which include the experiment design question, also have some questions are not tests itself but produces restricts to the experimental study and affects the experiment advances, there will be need time to solve these questions and need space, understand and support.In the foundation of the analysis obtains the effect, in further, I propose the strategy about learning environment optimization, which need the teacher base the teaching practice, thoroughly understood education idea of the new curriculum and the construction principle, holds the biology discipline characteristic, use direct-viewing silence knowledge, carry on the research about the development of school texts and curriculum resources, open up the student vision, enhance the situation variant, help the student migrate knowledge, carry out development teaching strategy, adjust teaching behavior, and persist in reconsidering teaching behavior, truly form the harmonious interaction relations between the teacher, the student, the resources and the goal.In brief, learning environment construction of the biology Constructivism is base on the new biology curriculum reform, constructs diligently the construction principle learning environment, which conforms to the education for all-around development, have close integration with the biological discipline characteristic and manifest it. It take the education for all-around development as the highest policy idea, take the innovation ability raise and the study quality enhancement as the pursue, take making the students learn how to live and the return life as end-result. Meanwhile, teacher should displays their function as a helper or supporter fully, we should carry on the omni-directional ponder and design about the following aspects: the teaching goal design, the curriculum resources development, the cognition tool choice and the use, the emotion manner values penetration and influences and so on.We should make constructs the construction principle localization, the discipline, truly achieve constructs the construction principle to implement and obtain a tangible effect in our biology teaching practice, and let students study biology knowledge with joyful and interests, raise their scientific accomplishment, consequently enhance the core competitive ability.
