Implementation Of The Online Design Thinking Tool And Analysis Of Collaborative Design Process

In recent years,the importance of design thinking in college engineering education has been paid more and more attention.The teaching mode adopted in this study is based on UCD(User-Centered Design)methodology of design thinking classroom group collaboration process(hereinafter referred to as "collaborative design").This teaching mode is applied to the classes of innovative thinking or innovative methods in engineering universities.The students are required to use UCD methods(such as sympathy map,four-quadrant method,etc.)to carry out innovative design and finally submit their works.This paper studies the data collection and behavior modeling of online collaborative design process,puts forward the relevant theoretical framework,and develops an online design thinking collaboration tool for innovative method courses,which verifies the feasibility of the research conclusions.The research goal of this paper is:explore the actual needs of teachers for collaborative design of classroom groups in innovative method courses,and implement the online design thinking collaboration tool applied to the classroom groups;according to the relevant data collected by the online tool,provide solutions or analysis for the following two research problems,that is,how to evaluate the degree of individual participation of student groups in the collaborative design process,and how to analyze the feedback states of interaction of students that are not easy to find and supervise in the process of collaborative design.The innovation of this paper is mainly reflected in three aspects:1.Aiming at the problems of complex analyzable dimensions and scattered teachers' needs in collaborative design process,this paper proposes to model the structural elements of collaborative design process,which is divided into three dimensions:consensus of points,behavior models and social relationships;2.Aiming at the problem that it is difficult to evaluate the individual participation in the collaborative design process,AHP and ANP methods are used to determine the weights of evaluation indices,and the weighted formulas of individual participation in the evaluation group are obtained,and the rationality measure is verified;3.Aiming at the problem that it is not easy to find the interaction state of students in the process of collaborative design,this paper puts forward the use of social network to form a method system process,analyzes the interaction core members,edge members and isolated members at the individual level,the cooperation closeness and the group interaction mode at the group level,and uses the experiment data of 36 groups(4-5 people in each group)to verify its feasibility.The main conclusions are as follows:1.AHP and ANP methods are used to determine the weights of evaluation indices,and all kinds of behavior data collected by the online tool are used as evaluation indices to obtain the weighted formulas of individual participation in the evaluation group,which has feasibility and application value;2.Using independent sample t-test and Spearman correlation coefficient,after eliminating the outliers,using the actual data of 142 students,it is proved that compared with the correlation between output behaviors and output results,the correlation between interactive behaviors and output results is weaker,which provides data support for the necessity of subsequent interactive behavior analysis;3.By using the relevant methods of social network,this paper analyzes the interactive behavior in the online tool,and forms the interactive analysis method system of collaborative design,which is proved to be feasible and practical by experiments.
