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.     

委托代理理论视野下职业教育第三方评价:潜在风险、行为博弈与应对策略

职业教育第三方评价中存在“套层式”的委托代理关系。由于客观存在的评价者与评价对象之间的信息不对称,主观层面二者的评价目标冲突,以及评价机构和评价者之间的非平等博弈行为取向,从而引发了道德风险和逆向选择风险。要解决上述问题,建议采取以下措施:形成和完善满足多样化评价需求的评价导向与标准,建立以激发评价双方合规行为为目的的约束与激励机制,健全以第三方机构为主体的“代理人市场”,完善以尊重与保护相关者利益为前提的多主体参与机制,优化“质”与“量”有机结合的评价过程与方法等。

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.

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。
