Research On The Practice Of High School Biology Unit Instructional Design Based On The Integration Of Teaching,Learning And Evaluation

China's Ministry of education has specified the core literacy of Chinese students' development and incorporated it into the curriculum standards of various disciplines.Among them,the curriculum standard of biology for senior high school(2017 Edition)(hereinafter referred to as the curriculum standard)has made clear provisions on the core literacy of biology in senior high school,that is,the requirement for students in knowledge is no longer simply "rote learning",but the need to be able to transfer and apply knowledge in situations.Students' systematic understanding of knowledge is the premise of transfer and application.Unit teaching can avoid the disadvantages of "fragmentation" of knowledge in traditional class teaching,build knowledge system for students,preset learning support,and enable students to integrate what they have learned.In the process of promoting students' learning,teaching evaluation plays an important role."Teaching,learning and evaluation" integration mode takes teaching objectives as the command,presupposes evaluation standards,carries out evaluation activities,infiltrates evaluation into all aspects of teaching,and emphasizes solving relevant problems in time.Therefore,the author has carried on the practical research of unit teaching design based on the integration of "teaching,learning and evaluation".Through reading and reviewing the relevant research literature,defining the core concepts,sorting out the existing research results of unit teaching design method and the idea of "teaching,learning and evaluation" integration.Then,the current situation of teaching evaluation of middle school biology teachers was investigated,and the problems in teaching evaluation were found.Combined with the above results,the author constructs the steps of unit teaching design based on the integration of "teaching,learning and evaluation".Then,taking the practical research method,the paper designs the case of "ecosystem and its stability" in the fifth chapter of compulsory three(2004 Edition),selects four parallel classes of senior two in a senior high school in Liuyang City as the research object,and collects the data of knowledge framework diagram,unit test results,teacher-student interview results,etc.in the research process The influence of the unit teaching design of "evaluation" integration on the teaching effect.The main results of this study are as follows:The author found that the main problems in the teaching evaluation of middle school biology teachers are as follows:(1)61% of the teachers simply equate the evaluation with classroom evaluation,ignoring that the evaluation should run through the whole teaching process;(2)Most teachers do not pay attention to the consistency of evaluation criteria,evaluation activities and teaching objectives;(3)In the middle school biology classroom,the evaluation subjects tend to be diversified,but teachers pay less attention to group evaluation;(4)The evaluation methods used by middle school biology teachers are still single,and the utilization rate of formative evaluation methods is low;(5)Lack of presupposition of oral evaluation dimension,teachers' evaluation feedback consciousness needs to be strengthened;(6)In the process of evaluation feedback implementation,most teachers can not take into account all levels of students in the class,especially the less advanced students,so the implementation of evaluation feedback needs to be improved.Combined with the survey results and literature research results,the author constructs the unit teaching design steps based on the integration of "teaching,learning and evaluation".The specific contents are: planning unit,determining unit name and scope;Front end analysis,combing the internal logic of unit knowledge;The unit teaching objectives and class teaching objectives are formulated;Design the evaluation task and standardize the evaluation process;Section design,implementation of teaching objectives;Pay attention to the evaluation after class,and make up for the missing effectively;Reflection on practice and optimization of unit teaching design.This step emphasizes the integration of teaching evaluation into the whole teaching process,including classroom evaluation and after-school evaluation;In addition,we also pay attention to the effectiveness of the feedback of the evaluation results,that is,whether the problems found in the evaluation process have been effectively solved.For the design of evaluation criteria,see Chapter 3.Finally,according to the steps of unit teaching design based on the integration of "teaching,learning and evaluation",the author designs and practices the case.The practical results of the case showed that:(1)the unit teaching design based on the integration of "teaching,learning and evaluation" is helpful to improve students' academic performance.(2)It is helpful for students to understand the subject concept and construct the knowledge system of this module.(3)The students interviewed said that their participation in classroom Q & A,activities,discussions and other aspects has been improved.
