如何实现高职院校两级管理的若干思考

实施院系两级管理是高职院校发展的现实需要。建议从实施院系两级管理的基础条件出发,即从教师的思想观念、心理准备和管理水平出发,从树立责任意识、建立管理体系、健全监督机制、引导教师参与等四个方面有效推进院系两级管理,提高学院办学质量,促进学院发展。     

我国图书情报领域期刊论文的科学数据引用特征研究

[目的/意义] 探索期刊论文科学数据引用特征与规律不仅有助于描述学科领域对科学数据的利用情况，还能够揭示学术成果表达中的数据引用模式。[方法/过程] 以我国图书情报领域6种期刊2017年与2018年第一期刊载论文为样本，结合国家标准《信息技术科学数据引用》的引用元素，采用内容分析法从9个维度对样本论文的科学数据引用行为进行数据编码，应用统计学方法描述图书情报领域期刊论文科学数据引用特征并探索不同维度特征间的关联关系。[结果/结论] 图书情报领域期刊论文广泛引用来自国内外的统计整理类科学数据，对期刊论文中个人研究科学数据的引用量较大；科学数据引用标注方式与科学数据类型存在一定对应关系，但多样化的标注方式缺乏统一性；二手引用现象较为突出，二手引用程度与科学数据创建者类型相关。     

基于用户兴趣度量的知识发现服务精准推荐

[目的/意义]针对当前知识发现服务中存在的个性化程度不高和推荐效果不佳等问题，提出一种基于用户兴趣度量和内容分析的推荐算法。[方法/过程]文章通过特征词分布、LDA主题分布、引文结构网络三个维度构建学术资源模型，并通过对用户行为的度量，计算用户对其浏览学术资源的兴趣度，结合学术资源模型构建用户兴趣模型。将用户兴趣模型与学术资源模型匹配，计算其相似度，得到用户对每条学术资源的兴趣值，最后将兴趣值最高的TOP-N学术资源推荐给用户。[结果/结论]通过实验检验算法的有效性和推荐准确率，结果显示，本文从实时动态度量兴趣的角度，提出的推荐算法能较好地预测用户兴趣，推荐效果显著，为实现发现服务精准推荐提供思路。     

Exploring mechanisms of rapid automatized naming to arithmetic skills in Chinese primary schoolers

Rapid automatized naming (RAN) is associated with children's arithmetic performance, which is multifactorial by nature and consists of arithmetic fluency, arithmetic procedure, and word problems. Yet, it is unclear whether RAN can predict all key aspects of arithmetic skills independently and what cognitive mechanisms may explain this relation. Using a sample of Chinese primary school students (N = 170), results showed that while RAN was associated with all key aspects of arithmetic skills, the relations of RAN–arithmetic procedure and RAN–word problems may be dependent on that of RAN–arithmetic fluency. Supporting the processing speed hypothesis, results further suggested that processing speed may underlie the relation between RAN and arithmetic performance. Findings made unique contribution to understanding the effect of RAN on arithmetic performance and cognitive mechanisms that may underpin this association in the context of Chinese culture.

网络多媒体教学的辅助功能定位及实践

实践表明,部分教师在应用网络多媒体进行教学时却忽略了主体性的发挥,这一问题将严重削弱专业课程的教学效果。为此,应将网络多媒体技术严格定义在辅助功能的角色,并通过纠正教师教学的主观意识、完善教师教学的内容设计,以及强化教学效果的多方评价来优化网络多媒体教学的实践。     

The Effect of Visual‐Chunking‐Representation Accommodation on Geometry Testing for Students with Math Disabilities

Students who struggle with learning mathematics often have difficulties with geometry problem solving, which requires strong visual imagery skills. These difficulties have been correlated with deficiencies in visual working memory. Cognitive psychology has shown that chunking of visual items accommodates students’ working memory deficits. This study investigated the effects of visual‐chunking representation as a testing accommodation for improving students’ geometry problem‐solving performance. Participants were four third‐graders with difficulties in mathematics. An adapted reversal design was employed to examine the students’ performance changes during standard testing conditions and accommodated testing conditions. During the accommodated condition, students were presented with visual‐chunking images. Results suggested that the visual‐chunking representation accommodation improved students’ performance on geometry problem‐solving tasks, and an interview confirmed students’ preference for the visual‐chunking representation approach.     

Teacher Beliefs in Action: A Cross-Sectional,Longitudinal Follow-Up Study of Teachers' Personal Practical Theories

Based on a cross-sectional, longitudinal follow-up study of graduates from our master's-level elementary education program, in this article we examined changes in espoused beliefs elicited in the form of personal practical theories (PPTs) of three graduates with 2, 4, and 6 years of experience teaching in the same partnership school where they did their student teaching. We compared their original PPTs collected during their teacher education program with their current PPTs elicited in follow-up interviews, and then observed their classroom practices. Case summaries of these teachers are presented, and analysis and implications focus on changes in their PPTs, how their PPTs played out in their classrooms, and perceived barriers and supports to enacting their beliefs.
