Research On Design Of Collaborative Knowledge Construction Activities Integrating Reflective Evaluation

Collaborative knowledge construction is an important research direction in the field of learning science.It has always been a topic that has been widely concerned by educational researchers at home and abroad.Collaborative knowledge construction focuses on cultivating student collaboration and reflection,and the ability to demonstrate and improve collaborative viewpoints,which meets the requirements of education and teaching personnel training.Viewpoints are the core elements of the collaborative knowledge construction process.However,in the process of collaborative knowledge construction,team members often have insufficient argumentation,negotiation,and defense.It is difficult to improve the depth and breadth of views,and it is difficult to achieve deep knowledge construction.Reflective evaluation helps students review and reflect on their original views,evaluate and analyze the views shared by others,continuously improve and deepen their views,help students reflect on their participation and contribution in the activity process,and improve student collaboration.The current research on reflective evaluation supporting collaborative knowledge construction is only the final stage of setting reflective evaluation at the theoretical design level,which has limited effect on improving viewpoints.At the level of activity practice,students do not know how to reflect and what to reflect,indicating that students lack the guidance of specific strategies in the process,and have not formed a set of mature activity theory design framework.It can be seen that integrating reflective evaluation into the process of collaborative knowledge construction has research value.Based on this,the core research question of this study is raised: how to design collaborative knowledge construction activities incorporating reflective evaluation to improve the depth and breadth of knowledge construction perspectives.The research combines the actual teaching situation to construct a collaborative knowledge construction activity design framework that incorporates reflective evaluation.Based on this,three rounds of collaborative knowledge construction activities are designed to gradually improve the evaluation method of viewpoint improvement in collaborative knowledge construction.After the end of the activity,the effect of designing and implementing the collaborative knowledge construction activity incorporating reflective evaluation is evaluated.In this study,a total of 54 students in the third-year education technology major of a university were selected as the research object for a total of 16 weeks.Based on the knowledge construction theory and activity theory,reflective evaluation was incorporated into the design of collaborative knowledge construction activities.The specific operational principles and strategies,using a combination of design-based research methods,survey research methods,and related data analysis methods,have designed three rounds of collaborative knowledge construction activities that incorporate reflective evaluation.The purpose of the activities is to continuously improve views and Optimize the perspective structure,forming a student-led reflective evaluation,a diverse perspective to promote the construction of collaborative knowledge,and a visual perspective analysis technology to promote student reflection.Three principles are used as the basis for activity design and implementation.Each principle has a corresponding strategy.In the three rounds of activities,the strategy is continuously improved,iterated and optimized,and finally a mature theoretical framework for event design is formed.The results analysis and effect evaluation part qualitatively analyze and quantitatively analyze the students 'collaborative knowledge construction perspectives and reflective texts,and the students' perceptions and attitudes towards the activity process.In the end,the main conclusions of this study are as follows: 1.Reflective evaluation can promote the improvement of views within the group,and thus improve the quality of collaborative knowledge construction: in the process of collaborative knowledge construction,reflective evaluation can effectively promote the improvement of students 'viewpoints,enhance the negotiation perspective The proportion of sublimated views,and reflective evaluation helps students to monitor the progress of the evaluation group,review the ideas and collate ideas,and compare,question,and negotiate different views,and integrate the views for the next step of knowledge construction,which helps to achieve a common construction.aims.2.The design principles of collaborative knowledge construction activities incorporating reflective evaluation include: student-led reflective evaluation,diverse perspectives to promote collaborative knowledge construction,and viewpoint visual analysis technology to promote student reflection: the teacher 's process feedback strategy Helps stimulate student participation in tasks.Reflective scaffolding can help students refine their ideas,so as to get a deeper level of conceptual understanding,and improve their views.3.The integration of reflective evaluation in all stages of knowledge construction helps to improve the depth and breadth of views.This research is still inadequate.Due to the limitations of the conditions,the empirical research activities are relatively short.Three rounds of iterative design and implementation of activities are carried out.Subsequent research can extend the activity time and properly grasp the application of reflection strategies in activity design,such as increasing reflection The degree of freedom of the prompt language,expand the selection range of the research sample,increase the representativeness of the sample,etc.,in order to enhance the credibility of the research data.
