参与电子档案袋已被证明可以改善学生的学习。然而，是什么因素影响学生接受电子档案袋是一个需要仔细研究的问题。本研究的目的是探讨自我效能感、主观规范、享受感、计算机焦虑和经验对学生电子档案袋系统的感知易用性（PEOU）和感知有用性（PU）以及他们的行为意图（BI）的影响使用系统进行学习。要做到这一点，该研究测试和使用的一般扩展技术接受模型的电子学习（GETAMEL）的背景下，电子投资组合。有效的数据收集了242名英国本科生谁已被介绍给电子投资组合。使用SPSS软件对数据集进行分析。结果发现，学生对电子学档易用性的感知最佳预测因子是体验，其次是享受、自我效能和主观规范。学生对电子档案袋的感知满意度的最佳预测因素是感知易用性，其次是享受。知觉易用性和知觉易用性都能预测学生使用电子档案袋的行为意向。研究结果提高了对电子投资组合系统的接受程度，因此这项工作对电子投资组合的研究人员，开发人员和从业人员特别感兴趣。(C)2016爱思唯尔有限公司版权所有
Engagement with e-portfolios has been shown to improve students' learning. However, what influences students to accept e-portfolios is a question that needs careful study. The purpose of this study is to investigate the influence of Self-Efficacy, Subjective Norm, Enjoyment, Computer Anxiety and Experience on students' Perceived Ease of Use (PEOU) and Perceived Usefulness (PU) of an e-portfolio system and their Behavioural Intention (BI) to use the system for learning. To do this, the study tested and used the General Extended Technology Acceptance Model for E-Learning (GETAMEL) in the context of e-portfolios. Valid data were collected from 242 UK undergraduate students who had been introduced to e-portfolios. The data set was analysed using SPSS software. Results showed that the best predictor of student's Perceived Ease of Use of the e-portfolio is Experience, followed by Enjoyment, Self-Efficacy and Subjective Norm. The best predictor of student's Perceived Usefulness of the e-portfolio is Perceived Ease of Use followed by Enjoyment. Both Perceived Ease of Use and Perceived Usefulness predict student's Behavioural Intention to Use the e-portfolio. The findings improve understanding regarding acceptance of e-portfolio systems and this work is therefore of particular interest to researchers, developers and practitioners of e-portfolios.
