Research On The Development And Application Of High School Biology Case Teaching Resources

In 2017 the new course standard issued by the ministry of education in our country,to articulate the core literacy biological disciplines,case teaching method reflect basic idea of biological subject core accomplishment,but just beginning a case teaching in the field of biology,high school biology teaching resources.To this end,the author aimed at o 'clock the content of high school biology "steady state and environment" of development and the application of case teaching resources,to development and application for first-line teachers provide reference case teaching resources,improve the classroom teaching effect.This study used literature research,experience summary method,case method,the information method,classroom observation method,interview method,from the high school biology teaching resources development and application of the two aspects are studied.Case teaching resources development steps from the following aspects:the preparation for case teaching resources development to determine the case teaching resources development principles to determine the case teaching resources characteristics,determine the case teaching resources development approach to case teaching resource processing,develop case teaching resources.Case teaching resources development should follow the principle of objective and scientific,problematic and instructive principle,interest and the principle of indirect and make developed in case of authenticity and situational teaching resources,typicality,timeliness and interest,purpose,and the characteristics of the problematic.Before the development of the case teaching resources,it is necessary to thoroughly read the subject curriculum standard,study the content of the textbook,understand the students' inner needs,and formulate the teaching objectives.In the process of the case teaching resources development,via the Internet and television,medical journal periodicals and extracurricular reading materials,teaching material of reading materials and reference books,these ways for development,the resources should be developed to filter,classification and edit three procedures of processing,finally present the case teaching resources are developed,with text,images and video resources three types.Will be developed in case of high school biology teaching resources for the application and implementation of the concrete application of case teaching resources in the classroom can be divided into the selection of case teaching resources,teaching resources present,students analyze the case teaching resources for final discussion and teachers comment on the four links.In the application of case teaching resources after the following conclusions:(1)the case teaching resources in the application process to give full play to students' "three features" principle,the principle of ability training,the principle of adaptive principle and enlightening.(2)the in class guide stage,it is better to select images or video resources,before the broadcast images or video resources,to proceed or to ask questions,lets the student with problems to see will be more targeted;In the explanation stage,the knowledge content should be interspersed with the case teaching resources,so that the students can better understand and construct the knowledge.In the exploratory stage of knowledge,the selected case teaching resources should put students in a dilemma and arouse students' desire to explore.In the review stage,the case teaching resources can be introduced into the exam to consolidate and check the students' mastery of the knowledge content.(3)for simple knowledge,there can be many cases teaching resources;For complex knowledge,it is better to choose a simple case teaching resource,but it is not suitable for the application of teaching resources.
