Research Of "Accompanying Evaluation" Activity Based On Dynamic Learning Data Stream

With the technologies such as big data and learning analysis widely used in teaching and learning,data collection,processing and analysis have become one of the important research hotspots in information education.Especially with the continuous deepening of smart education,the new classroom with smart equipment has become the main place where teaching and learning behaviors occur,providing more,smaller and higher frequency data collection,processing and analysis.The powerful technical conditions provide a realistic possibility to play the diagnosis,adjustment,guidance,incentives functions role of the evaluation,and to enhance the “accompanying” nature of evaluation.In this context,guided by the concept of “assessment for learning”,strengthening the “accompanying” orientation of teaching evaluation to make it be data-oriented,tracking the entire process of teaching,and oriented to the overall development of students,positioning students' progress and development,grasping students' weak point and shortcomings,and supporting teachers to adjust teaching progress and processes in a timely manner,and providing targeted counseling and answering questions are of great significance for enhancing the multi-dimensional role of evaluation and improving the development of students.Based on this,the research focus on the main problem that “how to use dynamic learning data in the smart classroom to carry out ‘accompanying evaluation'”,and its corresponding three sub-questions:(1)What is “accompanying evaluation” and what is the current status of data-based “accompanying” evaluation?(2)How does the learning data flow in the smart classroom,And what is the evaluation significance of these data?(3)How to use dynamic learning data to construct the “accompanying evaluation” framework,and how effective is the framework? To solve the above problems,the research mainly adopted quasi-experimental method,as well as classroom observation and questionnaire,the research has been carried out in the middle school mathematics course.Based on the current situation of classroom evaluation and the concept of “accompanying evaluation”,the research first puts forward the five elements that constitute the “accompanying evaluation”,namely the purpose determination,stage division,content selection,subject selection,tool design,meanwhile some principles and strategies for designing and implementing “accompanying evaluation” was figured out.Then guided by the concept of Data Flow,as well as the generation,flow and conversion of dynamic learning data in smart classroom,the data flow chart for the smart classroom was drawn and the evaluation value of these data was analyzed;Finally,taking the learning data flow as the context and five elements as constituents,a “accompanying evaluation” activity design framework including three nodes of academic condition diagnosis-lesson preparation,interactive participation-teaching,effect testing-migration was constructed.The study first worked out then guided by the concept of Data Flow to draw a data flow graph based on clues in the smart classroom teaching process;Then,based on the current situation of classroom evaluation and the concept of “accompanying evaluation”,combined with the needs and purposes of evaluation,five major elements were proposed to transfer “accompanying evaluation” to classroom evaluation,namely,stage division,purpose determination,content selection,subject selection,tool design;Next,the concept of “accompanying evaluation” was introduced into the three stages of smart classroom(situation diagnosis-lesson preparation,interactive participation-teaching,effect testing-migration),and a activity design framework was built.In order to verify the effectiveness of the framework,the study selected some students as the experimental object,launched the corresponding teaching and evaluation activity design and experiment,and collected the experimental results for effectiveness analysis,and also through interviews collected the suggestions of teachers and students on the design and implementation of the “accompanying evaluation” activity.The experimental results show that: “accompanying evaluation” can help teachers diagnose students' progress and progress in a timely manner,and can also enhance students' participation and enthusiasm for learning.In addition,when designing and implementing “accompanying evaluation”,we should take the teaching content and subject needs as the starting point,strengthen student evaluation participation,and establish a community to make teachers cooperate.Evaluation is for better teaching and learning.“Accompanying evaluation” is an attempt to strengthen the diagnosis,adjustment,motivation,and guidance functions of teaching evaluation.It is also the demand and direction of the transformation and development of teaching evaluation in the context of smart education.Guided by the “accompany evaluation” framework,design and act teaching and evaluation with the five elements,maybe can provide some reference for teachers to change.
