大学生的化学自我效能感对自我调节学习策略及学业成就的影响研究*

大学生的学业成就是衡量高等教育质量的重要因素之一。由社会认知理论、建构主义学习和人本主义学习理论可知,高校大学生的化学自我效能感应能促进自我调节学习策略的运用,对学业成就与综合素质提升具有积极效应,但仍需要进行验证。故本研究目的:探讨高校大学生的化学自我效能感对学业成就的影响性,并考察自我调节学习策略的中介作用。研究方法:采用大学生的化学自我效能感量表、自我调节学习策略量表、化学专业学业成就量表等工具,通过整群抽样的方式,对国内某高校的536名化学化工专业大学生进行问卷调查。研究结果显示:大学生的化学自我效能感与化学专业学业成就显著正相关;大学生的化学自我效能感与自我调节学习策略显著正相关;自我调节学习策略与化学专业学业成就显著正相关;自我调节学习策略在化学自我效能感与化学专业学业成就之间起部分中介效应。     

A note on Pythagorean triple preserving matrices

Several authors have found many Pythagorean triple preserving matrices in recent years. The purpose of this note is to show that all these matrices, and in particular the results published in Deshpande's 2001 paper are special cases of the earlier results obtained by Palmer, Ahuja and Tikoo.

Mathematical literacy in undergraduates: role of gender,emotional intelligence and emotional self-efficacy

This empirical study explores the roles that Emotional Intelligence (EI) and Emotional Self-Efficacy (ESE) play in undergraduates’ mathematical literacy, and the influence of EI and ESE on students’ attitudes towards and beliefs about mathematics. A convenience sample of 93 female and 82 male first-year undergraduates completed a test of mathematical literacy, followed by an online survey designed to measure the students’ EI, ESE and factors associated with mathematical literacy. Analysis of the data revealed significant gender differences. Males attained a higher mean test score than females and out-performed the females on most of the individual questions and the associated mathematical tasks. Overall, males expressed greater confidence in their mathematical skills, although both males’ and females’ confidence outweighed their actual mathematical proficiency. Correlation analyses revealed that males and females attaining higher mathematical literacy test scores were more confident and persistent, exhibited lower levels of mathematics anxiety and possessed higher mathematics qualifications. Correlation analyses also revealed that in male students, aspects of ESE were associated with beliefs concerning the learning of mathematics (i.e. that intelligence is malleable and that persistence can facilitate success), but not with confidence or actual performance. Both EI and ESE play a greater role with regard to test performance and attitudes/beliefs regarding mathematics amongst female undergraduates; higher EI and ESE scores were associated with higher test scores, while females exhibiting higher levels of ESE were also more confident and less anxious about mathematics, believed intelligence to be malleable, were more persistent and were learning goal oriented. Moderated regression analyses confirmed mathematics anxiety as a negative predictor of test performance in males and females, but also revealed that in females EI and ESE moderate the effects of anxiety on test performance, with the relationship between anxiety and test performance linked more to emotional management (EI) than to ESE.     

大学生网络成瘾与拒网自我效能及网络自我效能的关系探讨

采用问卷调查方法,对浙江大学和西安电子科技大学的420名大学生网络成瘾状态和拒网自我效能进行了研究,探讨大学生网络成瘾与拒网自我效能及网络自我效能之间的关系,以期对网络成瘾进行预判,并为进一步的网络成瘾干预提供理论基础.研究应用卡方检验分析不同拒网自我效能、网络自我效能组间网络成瘾状态的差异,运用相关分析研究网络成瘾与拒网自我效能、网络自我效能的关系,最后利用多元线性回归法,分析影响网络成瘾的主要因素.研究表明：大学生网络成瘾、网络成瘾倾向组比例分别为12.3%和19.1%,东西部院校之间没有差异,网络成瘾量表总分与拒网自我效能总分及各维度得分呈现显著负相关,而网络成瘾量表总分与网络自我效能总分关系不显著,拒网自我效能较低的大学生其网络成瘾比例高于拒网自我效能高的大学生;拒网自我效能中上网的刺激源和习惯性反应两维度是影响大学生网络成瘾的主要因素.本研究结果提示,增强大学生的拒网自我效能对预防网络成瘾可起到积极作用,提高大学生抵抗网络不良刺激的能力和养成良好的作息习惯是预防网络成瘾的关键.

Online targeted ads: Effects of persuasion knowledge,coping self-efficacy,and product involvement on privacy concerns and ad intrusiveness

This study conducted an online experiment to examine how persuasion knowledge of online targeted advertising (OTA), coping self-efficacy, and product involvement influenced the perceptions of privacy concerns and ad intrusiveness. These findings indicated that persuasion knowledge increased coping self-efficacy, which, in turn, influenced privacy concerns and perceived ad intrusiveness. Furthermore, the relations between coping self-efficacy and the evaluations of the OTA varied, depending on levels of product involvement. Specifically, when participants had high product involvement, their perceptions of privacy concerns and ad intrusiveness increased as their coping self-efficacy enhanced. However, those relationships did not appear among participants with low levels of product involvement. Theoretical and managerial implications of these findings are discussed later.
