| The application of project-based learning has promoted changes in teachers’ and stude nts’ teaching concepts and models,but there are problems such as restricted student subjecti vity,dysfunctional grouping and an imperfect evaluation system.This study uses action res earch to improve the project learning model and constructs a model for the application of pr oject learning in integrated practical activities in primary schools(identifying projects,plan ning,implementing,presenting work,and evaluating and reflecting),and conducts three ro unds of action research over a 12-week period.Each round was based on the "Plan-Act-Obs erve-Reflect" process,and combined with observation and interview methods to collect dat a for design optimisation.The first round was based on the theme of ’Animals have great skills’ and aimed to enh ance student agency.The study found that there was a lack of ability among the students du e to the group leader’s "single-mindedness".The following adjustments were made to addre ss these issues: increase the responsibility of group members and add technical guidance.The second round of the project,entitled "I Organise the Flea Market",aimed to optim ise group work and the division of labour.The study found that the participation of the proj ect subjects was uneven.The following adjustments were made to address these issues: a su pport programme was set up for marginalised students.The third round,with the theme of ’I am a school communicator’,aimed to design a m ultiple assessment with work as the core.Students’ motivation to participate in activities,in dependent thinking and self-directed learning,reflection and communication,and creativity and collaboration have all improved after the third round of action research.However,ther e are residual problems: the project evaluation lacks a long-cycle process evaluation,which can still be further improved through action research.After three rounds of action research,the project learning of integrated practical activit ies in primary schools has been improved from "yes" to "yes",and the following conclusion s have been drawn: firstly,the analysis of the internal structure of activities is an important grasp of project learning;secondly,the activity context that gives a sense of real participatio n is a prerequisite for project learning.Thirdly,the creation of cooperative groups and the di vision of labour is an effective way of project learning;fourthly,multiple assessments base d on students’ work is an important guarantee for project learning.Based on this,this study proposes several suggestions for implementation: firstly,analyse the teaching system as a w hole to ensure the balance of all elements;secondly,optimise the project learning situation t o realise students’ subjectivity;thirdly,arrange students’ grouping scientifically to improve group cooperation;fourthly,establish a multiple assessment system to optimise the way of course evaluation. |
