手持技术数字化实验慕课使用意愿的影响因素研究——基于TAM3模型的PLS-SEM分析

Study on the Influencing Factors of the Willingness to Use the Handheld Technology Digital Experiment MOOC Using PLS-SEM Measurement Based on TAM3 Model

在第三代技术接受模型(TAM3)的理论基础上,以华南师范大学化学学院2017级职前化学师范生为研究对象,构建手持技术数字化实验慕课的使用意愿模型。利用SmartPLS3.0软件,以偏最小二乘结构方程实证该模型的科学性。结果发现:(1)主观规范、产出品质和个体创新对感知有用性存在显著的正相关;(2)自我效能和感知愉悦性对感知易用性存在显著的正相关,而个体创新对感知易用性的影响并不显著;(3)感知易用性对感知有用性存在显著的正相关,2者对行为意向有显著的直接影响,而主观规范对行为意向的影响并不显著。基于以上结果,对手持技术数字化实验慕课的建设提出对策建议。

Based on the theoretical basis of Technology Acceptance Model 3(TAM3),with the pre-employment chemistry teachers in grade 2017 from the College of Chemistry of South China Normal University as the research object,a model of the willingness to use the handheld technology digital experiment MOOC was constructed.The study uses SmartPLS3.0 software to demonstrate the scientific nature of the model with partial least squares structural equations.The results found that Subjective Norm,Output Quality,and Personal Innovativeness have a significant positive correlation with Perceived Usefulness.Second,Self-Efficacy and Perceived Enjoyment have a significant positive correlation with Perceived Ease of Use.Personal Innovativeness has a significant positive correlation with Perceived Usefulness while the effect of Perceived Ease of Use is not significant.Third,Perceived Ease of use has a significant positive correlation with Perceived Usefulness.The two have a significant direct impact on Behavioral Intention,while Subjective Norm has no significant impact on Behavioral Intention.Based on the above results,countermeasures and suggestions are put forward for the construction of the handheld technology digital experiment MOOC.
