Does using e-portfolios for reflective writing enhance high school students’ self-regulated learning?

The study aims to examine whether reflective writing using e-portfolios enhances high school students’ self-regulated learning. Participants included two classes of eighth-graders majoring in Information Processing and taking a course called ‘Website Design’ at a vocational high school in Taiwan. There were 41 students, with 18 males and 23 females. The experiment lasted 10 weeks, and students used e-portfolios to reflect on their learning. The results showed that students after using e-portfolios to reflect on their learning had significantly better self-regulated learning than before. This indicates that using e-portfolios for reflection enhanced self-regulated learning. It also shows that high-reflection students had significantly better self-regulated learning than moderate-reflection and low-reflection students, which implies that reflective performance had a significantly positive effect on self-regulated learning.     

“I am not simply learning and regurgitating information,I am also learning about myself”: learning portfolio practice and online distance students

This case study explored the experience of learning portfolio practice and whether learning portfolio practice facilitated the development of critical thinking skills among online distance students. Data were generated using the participant learning portfolio entries and two-time semi-structured interviews. Five themes were constructed in the data-led thematic analysis: being an online distance student, the experience of learning with a learning portfolio, my approach to learning, thinking critically in my learning portfolio, the sociology discipline context. Findings indicate that learning portfolio practice can enhance the nature of the learning experience by providing students with a personal space to evaluate their own learning, to process their thoughts and experience and to document their lives and learning in an authentic and meaningful way. The findings suggest that learning portfolio practice can facilitate the development of critical thinking skills within a disciplinary context.     

Presenting Complex Teacher Evaluation Data: Advantages of Dossier Organization Techniques Over Portfolios

The development of extensive and authentic teacher evaluation raises questions about how best to organize and present the increased amount and variety of assessment materials. Portfolios have been suggested for teacher evaluation because they are well suited to capture the complexities of teaching. However, portfolios 1) are difficult to judge, 2) are difficult to archive, 3) lack key information, 4) miss excellent teachers with simple materials, 5) rarely plan for audiences, 6) distort when required, and 7) bring conflicts of interest. Teacher dossiers are compressed collections of objective data which are easier to judge, demonstrably reliable, and cost-effective.     

投资组合信用风险的测度和优化——基于Copula理论

使用四种copula(即Gaussian copula、Student’s t-copula、grouped t-copula和Clayton n-copula)对投资组合信用风险进行度量,并在此基础上,利用线性规划方法优化投资组合。研究结果比较发现,几种copula中t-copula度量投资组合信用风险相依最合适,并给出了相应的最优资产配置。     

基于专利共被引聚类和组合分析的产业关键技术识别方法研究——以作物育种技术为例

[目的/意义]基于专利共被引聚类和专利组合分析构建关键技术识别分析框架,可为产业、企业决策和规划提供参考依据。[方法/过程]首先通过专利共被引聚类获得若干个聚类簇;再通过领域专家对聚类簇进行判读和命名;最后从专利活动和专利质量两个维度对聚类簇进行专利组合分析,其中专利申请数量和被引频次均较高的专利簇即为关键技术。[结果/结论]与已有方法比较研究表明,本方法不仅可以有效识别产业关键技术,还能在中观的产业层面揭示出切合实际需求的技术方向,也可为企业根据自身需求制定不同的技术发展战略提供指导。     

基于创新价值的农业科技项目立项评价指标体系构建及实证研究

通过文献研究、案例分析与专家访谈,初步提出农业科技项目的创新性评价指标后基于调查问卷的大样本数据,选用验证性因子分析对指标进行删减与分类,得到9个一级指标及35个二级指标,这是在农业领域首次以科技项目创新价值为核心的立项评价指标。而后在主观层次分析法与客观熵值法基础上,运用层次-熵值组合赋权方法得到指标权重。该方法与较为常见的偏差最大化组合赋权法所得的权重数值具有较高的相关度,而定量评价结果与实际同行评议结果具有较高的相似度。

全球专利发展现状及其启示 ——基于《2020世界知识产权指标》专利数据分析

针对世界知识产权组织在日内瓦发布的《2020世界知识产权指标》报告中的专利数据展开分析.《2020世界知识产权指标》报告显示,我国专利申请总数和授权总数均位列世界第一.但数据显示,我国居民海外专利申请量还远远低于美国、日本等国家,我国海外专利布局区域不平衡,我国申请人有效专利流失严重,平均使用年限偏低.为此,我国应加快...     

资源型城市绿色增长能力评价研究

资源型城市是我国重要的战略保障基地,其绿色增长能力成为彰显国家绿色增长水平的重要途径。本文构建了以社会经济、资源环境、生活质量为基础系统,以政策支持为交互系统的资源型城市绿色增长评价模型,以2000-2013年17个典型资源型城市为研究对象,运用三角模糊熵组合赋权的灰色关联投影方法测算绿色增长指数,进行绿色增长能力评价。研究结果表明:三角模糊熵组合赋权的灰色关联投影法是评价资源型城市绿色增长能力的有效方法。国家相关政策的颁布实施是促进资源型城市实现绿色增长的主要动力。中国资源型城市绿色增长能力不断提高,依据绿色增长能力的大小,可将中国资源型城市划分为创新升级型、发展成熟型、稳步提升型和意识崛起型四个发展类型。
