Research On Dynamic Mathematical Software Evaluation Based On User Experience

With the comprehensive arrival of the Internet era,the Internet has gradually developed its focus to the field of education.The promotion of educational informatization is conducive to cultivating students' information literacy,improving students' teaching efficiency and promoting educational fairness.Educational software is one of the important means to promote educational informationization and has important practical significance to promote teaching methods and educational reform.Dynamic mathematics software is one of the products of educational software.However,at present,dynamic mathematics software emerges in an endless stream,and users have greater blindness and randomness in choosing dynamic mathematics software.The current dynamic mathematics software in the market has the following two problems.First,the software's usability,usability and ease of use are poor,and the function is single and incomplete.Second,more attention is paid to the usability and more functions and technologies of the software,but the sense of user experience is ignored,and it is difficult to meet the needs of users,resulting in poor learning effect.Therefore,how to choose a high quality and appropriate dynamic mathematics software has become an urgent problem.It is necessary to build an evaluation index system of dynamic mathematics software from a scientific perspective to help evaluate the quality of the software.In this paper,from the perspective of the user experience,combined with the user experience theories,dynamic mathematics software and software evaluation research status and research methods,I built the evaluation index system of dynamic mathematics software based on user experience.In the result,I enriched the research of software evaluation system in our country,and provided an instructional strategy for learners and teaching people to choose suitable dynamic mathematics software,also provided the thoughts of design and improvement for software developers,to standardize the quality management of dynamic mathematics software market in China.In order to build a scientific evaluation index system and realize the above significance,the main research work and contributions of this paper include:1.Based on the research of user experience classic model,combining with dynamic mathematics software unique subjects and the learning theory,I put forward to Clarity,Credibility,Efficiency,Motivation and Subject as five core elements of dynamic mathematics software CCEMS model.Five core elements interrelate and influence each other to form a complete model of dynamic balance.2.Based on CCEMS model,Delphi method was used to revise the preset evaluation index system,and five first-level indicators--Clarity,Credibility,Efficiency,Motivation and Subject were determined,as well as 15 second-level indicators and evaluation standard descriptions of second-level indicators.Then Analytic Hierarchy Process(AHP)was used to determine the weight value of each index,and finally a complete dynamic mathematics software evaluation index system was formed.3.The dynamic mathematics software evaluation index system based on user experience was used for an application example,and the evaluation scheme was designed to evaluate the user experience quality of Net Pad.According to the standards of the evaluation index system,the questionnaire was designed,the questionnaire was distributed,and the statistical data was collected and sorted out.The score of each secondary index and the weighted total score of the network sketchpad was 4.59(5-point scale),which showed that Net Pad had a good performance in user experience and could meet the needs of mathematics teaching.And in view of the score of the secondary index analysis of the shortcomings of Net Pad,I put forward some constructive suggestions.This application example not only proves that Net Pad has a high user experience,but also confirms the operability and implementation of the evaluation index system.
