基于图书馆学五定律的高校图书馆读者借阅权限设置合理性分析

对当前高校图书馆读者借阅权限设置的现状进行了概括总结,认为目前按读者类型分别设置借阅权限、借阅权限设置粗糙且长期固化、特殊文献只限于读者阅览或特定读者使用、读者超越借阅权限需承担一定后果等做法缺乏科学性.以图书馆学五定律理论为基础,对读者借阅权限的合理设置提出一些参考性建议.     

计算机专业多课程交叉教学研究--以《数据库》课程为例

计算机专业课程众多,且课程之间联系紧密,知识内容具有交叉性,而传统的“孤立式”教学方式未注重课程之间知识的联系,不利于学生对知识体系的系统性把握,且各门课程知识点的重叠性在一定程度上加重了学生的负担。以《数据库》课程为例,提出交叉知识点融合教学、多课程捆绑式教学、交叉综合实训课程和面向应用型人才培养目标的多课程体系群四种多课程交叉教学模式,构建多层次的多课程交叉教学模式,以促进应用型计算机专业人才的培养。     

大数据领域的主题分析--基于WOS和Wikipedia的互证研究

利用WOS( Web of Science)和Wikipedia两种数据源,对大数据相关的内容进行词频统计、文本归类分析,得出两种数据源下大数据主题的共识和差异,并进一步梳理提炼出大数据领域的主题类别。共同的类别包括整体角度、技术层面、应用层面、实体和活动等,进一步细分的主题包括数据及数据源、大数据处理和分析技术、大数据系统和应用、国家地区以及企业的推动、社会和人的讨论、行业和学科变化等。最后论文还结合相关数据探讨了大数据领域的研究前沿。

Unveiling the colour palette of Arraiolos carpets: Material study of carpets from the 17th to 19th century period by HPLC-DAD-MS and ICP-MS

Wool samples collected from thirteen Arraiolos carpets from the 17th–19th century belonging to the National Museum of Ancient Art (NMAA, Lisboa, Portugal) collection were analysed to identify the natural dyes and mordants employed in the traditional dyeing process, in a way to complement and improve actual knowledge on this rugs. Natural dyes were extracted from Arraiolos historical wool fibres using a mild extraction method, followed by high-performance liquid chromatography with diode array and mass spectrometry detection (HPLC-DAD-MS) for compound identification. Colourimetry was used to measure colour parameters in all historical samples. Quantification of mordants in the historical fibres was carried out by inductively coupled plasma-mass spectrometry (ICP-MS). Weld, indigo, spurge flax, brazilwood, madder and cochineal were identified as dye sources in the fibres. Alum was the most commonly used mordant, but the presence of iron and zinc was also detected in some darker samples. The use of madder and cochineal is not referred in the available historical dyeing recipes. This study also proved that the actual visual perception of these carpets is strongly affected by the natural dyes photodegradation, which was mostly unaccounted for before.     

The effect of goal-setting prompts in a blended learning environment—evidence from a field experiment

Previous literature has shown that task-based goal-setting and distributed learning is beneficial to university-level course performance. We investigate the effects of making these insights salient to students by sending out goal-setting prompts in a blended learning environment with bi-weekly quizzes. The randomized field experiment in a large mandatory economics course shows promising results: the treated students outperform the control group. They are 18.8% (0.20 SD) more likely to pass the exam and earn 6.7% (0.19 SD) more points on the exam. While we cannot causally disentangle the effects of goal-setting from the prompt sent, we observe that treated students use the online learning platform earlier in the semester and attempt more online exercises compared to the control group. The heterogeneity analysis suggests that higher treatment effects are associated with low performance at the beginning of the course.     

学习科学：何以为教学创新注入活力＊--2013学习科学研讨会综述

在最近召开的“2013学习科学研讨会”上,来自香港大学、北京大学、清华大学、南京大学、北京师范大学、华东师范大学、东南大学等高校和机构中的学习科学研究领域的学者以及实践领域的专家,共同商谈如何在已有研究基础上推进我国学习科学的深入研究和学科发展。与会代表普遍认为,学习是一个复杂现象,因此,需要不同学科、不同领域的研究者与教育实践者紧密合作,从不同层次出发研究学习。在推进学习理论发展的同时,从学习科学角度思考教育变革面临的挑战,从而为我国教育改革和创新提供新思路。     

The happy-fish-little-pond effect on enjoyment: Generalizability across multiple domains and countries

Academic enjoyment is an important educational construct given that it benefits students' engagement, persistence, wellbeing, and mental health. In this study, we examine two factors that determine this crucial emotion, namely student- and class-level achievement. Past research has been restricted to single-country or single-domain examinations of secondary school students, limiting generalizability of findings. To bridge this gap, we utilize the Trends in International Mathematics and Science Study and the Progress in International Reading Literacy Study (TIMSS-PIRLS) combined 2011 data (N = 180,084 4th-grade students, 37 countries). Our results provide robust evidence that student-level achievement positively predicts enjoyment in math, science, and reading, while the effects of class-level achievement are negative—the Happy-Fish-Little-Pond Effect. These results showed relative universality across the domains and countries examined.
