创造性科学问题提出材料的编制及效度研究

本研究通过对收集的科学发明创造实例进行整理,测量,访谈,再测量,建立拥有多项指标的创造性科学问题提出材料库,以期为研究创造性科学问题提出提供有效的测试工具。在材料库的建立过程中,对问题提出中的原型启发效应进行了探讨,结果表明,原型对创造性问题提出具有稳定的启发效应,并且这种启发效应在具有理科背景的个体上有更明显的效果。此外,创造性科学问题提出分数不仅与创造性成就倾向显著相关,且在企业环境中也显示出了对于不同创造力群体的有效鉴别

Validation and Compilation of the Creative Scientific Problem Finding Materials

On the basis of Nomophobia questionnaire of Caglar Yildirim & Ana-Paula Correia,the Chinese version of the Nomophobia scale was revised.Using Exploratory Structural Equation Modeling to investigate the structure of the scale,Secondly,the Item Response Theory was used for project analysis.At last,the Confirmatory Factor Analysis was used to verify the factor structure of the final scale.The final scale had 16 items and 4 dimensions,including the fear of being unable to obtain information,fear of losing convenience,fear of losing contact and fear of losing the Internet connection.Cronbach α of the whole scale was 0.931,the Cronbach α of four dimensions were 0.789,0.816,0.887 and 0.896.the data fits good with construction by using Confirmatory Factor Analysis(χ2/df=3.91,RMSEA=0.067,TLI=0.941,CFI=0.952,SRMR=0.04).Using Mobile Phone Addiction Tendency Scale as the criterion validity,the results showed that the correlation between the total score was 0.626,and the validity was good.The final scale item discrimination were between 1.734,4.806],the four-dimension averages were 2.1765,2.72,3.2925 and 3.883.The difficulty parameters were between -1.830,4.806].In conclusion,the Nomophobia scale revised by the study has a good reliability and validity and has excellent item property(difficulty,discrimination),which can be used for future researches
