大学生在线知识建构行为及序列模式分析     

冷静  路晓旭  宋金阳 《中国远程教育(综合版)》2022,(1)

为解决新时代下各种复杂问题,当代大学生应该具备知识建构能力,特别是学生能够通过在线协作平台不断进行提问、解释,从而共同解决问题并进行知识创造。由于学习过程数据可从在线学习平台获得,使得分析大学生知识建构的动态发展及序列模式成为可能。上海某高校教育技术专业的27名三年级学生参与了课程学习,并利用在线论坛进行了一学期的协作交互,共发帖787条。本研究采用内容分析法对所有帖子进行编码,利用滞后序列分析得到该课程三个协作阶段的编码行为序列。研究发现,随着协作的深入知识建构的层次逐渐提升,在不同协作阶段会出现不同的序列模式。分析在线学习行为及序列模式有助于教师更好地诊断影响学习结果的潜在问题,从而调整教学策略以促进其知识构建过程。  相似文献

面向协作学习多重投入特征画像的多模态学习分析     

马志强  孔伶玉  岳芸竹 《远程教育杂志》2022,(1)

群体投入特征画像是教育与信息技术交叉学科关注的重要研究议题。目前的研究,尚需要在群体投入维度与指标构建、多模态交互数据的融合表征,以及群体多维投入特征刻画等方面取得突破。鉴于此,如何采用多模态交互信息来表征协作学习参与者的投入状态,成为应对当前挑战的关键问题。因此,结合德尔菲法与层次分析法建立群体多重投入特征的分析指标及权重,利用多模态交互分析方法融合与表征多维投入特征,并从群体投入状态差异与时序变化等角度,刻画协作知识建构中参与者的投入特征。研究结果认为:行为参与、社会关系、观点建构和共享调节是刻画群体协作学习投入状态的重要指标,基于多模态数据刻画群体投入特征方法需处理的关键问题是多模态交互数据的融合比例与数据对齐方式;在群体知识建构活动中,个体在各子投入维度的不均衡表现与小组内部成员相互影响的投入表现是协作学习投入的主要特征。  相似文献

Evaluation and simplification of risk factors in FIGO 2000 scoring system for gestational trophoblastic neoplasia: a 19-year retrospective analysis     

Weng  Yang  Liu  Yuanyuan  Benjoed  Chitapa  Wu  Xiaodong  Tang  Sangsang  Li  Xiao  Xie  Xing  Lu  Weiguo 《Journal of Zhejiang University. Science. B》2022,23(3):218-229

Objective

The International Federation of Gynecology and Obstetrics (FIGO) 2000 scoring system classifies gestational trophoblastic neoplasia (GTN) patients into low- and high-risk groups, so that single- or multi-agent chemotherapy can be administered accordingly. However, a number of FIGO-defined low-risk patients still exhibit resistance to single-agent regimens, and the risk factors currently adopted in the FIGO scoring system possess inequable values for predicting single-agent chemoresistance. The purpose of this study is therefore to evaluate the efficacy of risk factors in predicting single-agent chemoresistance and explore the feasibility of simplifying the FIGO 2000 scoring system for GTN.

Methods

The clinical data of 578 GTN patients who received chemotherapy between January 2000 and December 2018 were retrospectively reviewed. Univariate and multivariate logistic regression analyses were carried out to identify risk factors associated with single-agent chemoresistance in low-risk GTN patients. Then, simplified models were built and compared with the original FIGO 2000 scoring system.

Results

Among the eight FIGO risk factors, the univariate and multivariate analyses identified that pretreatment serum human chorionic gonadotropin (hCG) level and interval from antecedent pregnancy were consistently independent predictors for both first-line and subsequent single-agent chemoresistance. The simplified model with two independent factors showed a better performance in predicting single-agent chemoresistance than the model with the other four non-independent factors. However, the addition of other co-factors did improve the efficiency. Overall, simplified models can achieve favorable performance, but the original FIGO 2000 prognostic system still features the highest discrimination.

Conclusions

Pretreatment serum hCG level and interval from antecedent pregnancy were independent predictors for both first-line and subsequent single-agent chemoresistance, and they had greater weight than other non-independent factors in predicting single-agent chemoresistance. The simplified model composed of certain selected factors is a promising alternative to the original FIGO 2000 prognostic system, and it shows comparable performance.

“一带一路”倡议与海外留学生来华:因果识别与机制分析     

吕越  王梦圆 《教育与经济》2022,(1)

教育国际化是当前各国构筑对外开放格局的关键模块,而“一带一路”倡议的纵深推进为我国留学生教育发展带来了良好契机。以2003—2018年196个国家和地区的来华留学生数据为样本,采用双重差分法检验了“一带一路”倡议是否能够促进海外留学生来华,并深入考察其作用机制。研究发现:(1)“一带一路”倡议的实施显著扩大了沿线国家的来华留学生规模,在经过一系列稳健性检验后,结论依然成立;(2)从作用机制来看,基础设施建设水平的提高,跨国投资规模的扩大和文化产品贸易程度的加深是“一带一路”倡议推动沿线国家留学生来华的重要途径。(3)异质性分析表明,“一带一路”倡议对留学生来华的促进效应集中在邻近国家和低收入国家,而对非邻近国家和高收入国家的来华留学生规模没有明显影响。此外,区分不同学历类别来看,相比非学历留学生,倡议对学历留学生来华有更为显著的促进作用,将有利于我国留学生学历结构的优化。  相似文献
