基于m-相依序列的学习机器相对一致收敛的界

为了研究m-相依序列下学习机器的推广性能,把基于独立同分布的结果推广到m-相依序列,建立采用ERM算法的学习机器的经验风险到它的期望风险相对一致收敛速率的界.并对m-相依序列现有的结论进行改进,得到了m-相依序列下,采用经验风险最小化算法学习机器的推广性能的界.

Comparing active delay and procrastination from a self-regulated learning perspective

Researchers have proposed that the act of postponing academic work may be divided into a traditional definition of procrastination, viewed as maladaptive, and adaptive forms of delay. Adaptive forms of delay may be more consistent with certain facets of self-regulated learning. The current study investigated this issue by examining whether the relations between aspects of self-regulated learning and active delay may be distinct from the relations these aspects of self-regulated learning have with procrastination. Among 206 undergraduates, procrastination was positively predicted by mastery-avoidance goals and negatively by metacognitive strategy usage, whereas active delay was negatively predicted by avoidance goals and positively by self-efficacy. Furthermore, students who reported higher levels of active delay also received better grades. These findings provide support that active delay is a distinct form of delay from procrastination that may be more positive due to its associations with some adaptive self-regulatory processes and academic achievement.     

信息环境下西部地区大学生英语学习现状及其原因分析——以四川外语学院为例

信息技术影响到外语教与学的方方面面。对学生进行调查后发现,近半数学生喜欢通过网络和手机等电子工具学习英语;有1／3左右的学生喜欢通过虚拟学习环境学习英语;只有很少一部分学生喜欢去自主学习中心学习英语。从学生视角对造成上述现象原因进行分析有助于帮助学生提高学习能力。     

Modelling parenting styles,moral intelligence,academic self-efficacy and learning motivation among adolescents in grades 7–11

The current study investigated the associations between three maternal and paternal parenting styles, moral intelligence, academic self-efficacy and learning motivation in three serial mediation models. Omani adolescents enrolled in 7th to 11th grades (N = 296) responded to an online survey containing demographic items and scales measuring the variables noted above. Results of Path Analysis indicated that the three models had a good overall fit. In detail, the three paternal styles (authoritative, authoritarian and permissive) had direct associations with moral intelligence and indirect associations with learning motivation. However, only two maternal parenting styles (i.e., authoritative and authoritarian) correlated directly with learning motivation and these two styles did not associate with moral intelligence. All effects were in the hypothesized direction except the effect of authoritative maternal and paternal styles. Moral intelligence had a positive direct correlation with students’ academic self-efficacy and learning motivation. Moral intelligence also mediated the negative associations between three types of fathers’ parenting styles and students’ motivation. Academic self-efficacy had a positive association with students’ motivation. These findings provided useful insights about the various association between external factors (e.g., parenting styles), internal factors (i.e., moral intelligence and self-efficacy) and students’ motivation among adolescents in middle and high schools.

Learning styles in engineering education: the quest to improve didactic practices

This article discusses a dilemma that engineering educators encounter when attempting to develop pedagogical methods: that of finding efficient and scientifically valid didactic practices. The multitude of methods offered by educational consultants is perplexing. Moreover, the popularity of commercially offered solutions such as learning styles testing makes them appear attractive. The study presents one case of application of learning styles, the consequent problems and evaluation of results. It concludes that the use of learning styles is not supported by current pedagogical theories. Practices to foster interdisciplinary understanding between learning sciences and engineering are proposed in order to improve engineering education, most notably collaborative projects between university departments.     

Learning science through writing: associations with prior conceptions of writing and perceptions of a writing program

Students in a large undergraduate biology course were expected to write a scientific report as a key part of their course design. This study investigates the quality of learning arising from the writing experience and how it relates to the quality of students’ preconceptions of learning through writing and their perceptions of their writing program that led to their report. Closed‐ended questionnaires investigating student conceptions and perceptions of writing, and approaches to writing, were completed by 121 students. Significant associations were found amongst qualitatively different prior and post conceptions of writing, approaches to writing and achievement. The results of the analyses suggest that the effective support of student experiences of writing reports requires teachers to be aware of the type of conceptions that students bring to their course and the perceptions they hold about the purpose of the writing program in which they are engaged.     

基于自主性学习的英语教学模式探究

传统的大学英语教学模式,教学效果不理想,引起众多批评。于是正在进行的大学英语教学改革里,提出要培养学生的自主学习能力,然而实践中出现对自主学习的认识偏差,忽视了课堂教学活动的重要性,轻视了教师的主导地位,对学生的主体地位的定位不准确等等问题。针对以上情况本文尝试探讨通过何种模式来培养学习者自主学习能力。
