摘要：
教育智能体(Pedagogical Agent,PA)对认知学习的作用是目前学界关注的热点问题之一,然而,已有研究尚未能对此给出明确的答案.为此,通过筛选并梳理2011至2019年间围绕教育智能体的实证研究文献29篇,分析PA研究的基本理论、观点和方法,可以发现,当前围绕教育智能体的原则或理论仍存在一定的争议.基于此,利用"教育智能体-应用情形"模型(Pedagogical Agents-Conditions of Use,PACU),并结合内容分析方法,从功能、设计、学习者和学习环境四个方面,对PA与学习表现、学习动机和认知负荷的影响关系进行分析发现,教育智能体的内部因素(功能、设计)是近十年研究的热点,智能化的情绪、认知调节功能以及视线指引功能,对学习表现和学习动机有显著促进作用;但对教育智能体外部因素(学习者、学习环境)的研究,还处于较为浅层的状态.因此,未来应以智能技术为支撑,由内及外全面、深入地开展研究,并从研究设计角度加强对各因素间调节/中介作用的关注.

摘要：
The contextual influences on technological pedagogical content knowledge (TPACK) enactment and the method of TPACK assessment remain to be important research topics. Discourse data of 81 teachers in an online professional learning community were collected and analyzed based on the framework of TPACK. Frequency distribution and time series characteristics of teachers’ knowledge domains were analyzed. In addition, epistemic network analysis was used to compare the epistemic network characteristics of teachers in the higher-score and the lower-score groups, different age groups, and post and reply groups. Results showed that teachers’ knowledge domains enacted in the context of online discourse were mainly pedagogical content knowledge and general pedagogical knowledge. The teachers in the higher-score group had a rich, organized and flexible knowledge structure of TPACK. Younger teachers had more connections between pedagogical knowledge and pedagogical content knowledge, while senior teachers had more connections between technological knowledge and pedagogical knowledge. The teachers in the reply group had more connections among the different categories of knowledge as compared to the post group. Finally, implications, limitations and future research were discussed. © 2019 British Educational Research Association

摘要：
Observing student body gesture has been widely used to assess teaching effectiveness over the past few decades. However, manual observation is not suitable for the automatic data analysis in the field of learning analytics. Consequently, a student body gesture recognition method based on Fisher Broad Learning System (FBLS) and Local Log-Euclidean Multivariate Gaussian (L 2 EMG) is proposed in this paper. FBLS is designed by introducing the discriminative information into the hidden layer of Broad Learning System (BLS) and reducing the dimensionality of hidden-layer representations. FBLS has superiorities in accuracy and speed. In addition, L 2 EMG, which is a highly distinctive descriptor, characterizes the local image with a multivariate Gaussian distribution. So L 2 EMG features are fed into the FBLS for recognition in this paper. Extensive experimental results on self-built dataset show that the proposed student body gesture recognition method obtains better results than other benchmarking methods. © 2019 World Scientific Publishing Company.

摘要：
This study investigated the relationships among teachers’ motivational beliefs, motivational regulation, and their learning engagement in online professional learning communities. More importantly, teachers’ online learning behaviors were collected and used as indicates of learning engagement. 520 teachers involved in a training program were surveyed. The results of regression analyses showed that teachers’ perceived task value positively predicted their online learning engagement. Moreover, teachers’ motivational regulation played a partial mediating role in the predicting power of perceived task value to learning engagement. In addition, the first half of the mediating path among perceived task value, motivational regulation, and learning engagement was moderated by teachers’ self-efficacy. The moderating effect on motivational regulation was higher for teachers with a high sense of self-efficacy than those with a low sense of self-efficacy. Therefore, it was suggested to assign learning tasks that meet the needs of teachers and pay attention to the cultivation of teachers’ self-efficacy beliefs to increase their learning engagement in online professional learning communities. The limitations and the future research directions were discussed. © 2019 Elsevier Ltd

摘要：
Magnetic field is an important knowledge point in junior high school physics discipline. Due to its invisible feature, students require to concretely perceive the magnetic field through experiments. However, the traditional experiment has some defects such as inconvenient operation and insignificant effect. Computer simulation technologies can solve these problems by virtualizing them, but it currently has some shortcoming in terms of its experience and credibility. Based on augmented reality technology and the idea of inquiry learning, this paper designs and implements an AR courseware for magnetic field teaching. The experimental experience is enhanced by the fusion of virtual and real while visualizing the magnetic line. Finally, a preliminary application is carried out.

摘要：
This study investigated whether video lectures instructed by a heightened level of expressiveness instructor were better than those instructed by a conventional level of expressiveness instructor or audio-only in promoting students' online learning, and what kind of effects do instructor's facial expressions have on students' learning. Three different types of video lectures (one with a heightened level of expressiveness instructor, one with a conventional level of expressiveness instructor and one with the instructor' audio only) were used to study the effects of instructor's facial expressions. Sixty-nine participants from Chinese Normal University were selected to learn with these video lectures. Results of this study indicated that video lectures with a heightened level of expressiveness instructor were better than those with a conventional level of expressiveness instructor and audio-only ones with regard to improving students' arousal level and learning satisfaction. Instructor's facial expressions had no significant influence on participants' short-term recall (p =.90), while instructor's facial expressions did influence students' medium-term recall (p =.03). Instructor's facial expressions played a key role in students' online learning. © 2018 British Educational Research Association

摘要：
Teachers' online discussion text data shed light on their reflective thinking. With the growing scale of text data, the traditional way of manual coding, however, has been challenged. In order to process the large-scale unstructured text data, it is necessary to integrate the inductive content analysis method and educational data mining techniques. An inductive content analysis on samples taken from 17,624 posts was implemented and the categories of teachers' reflective thinking were obtained. Based on the results of inductive content analysis, we implemented a single-label text classification algorithm to classify the sample data. Then, we applied the trained classification model on a large-scale and unexplored online discussion text data set and two types of visualizations of the results were provided. By using the categories gained from inductive content analysis to create a radar map, teachers' reflection level was represented. In addition, a cumulative adjacency matrix was created to characterize the evolution of teachers' reflective thinking. This study could partly explain how teachers reflected in online professional learning environments and brought awareness to educational policy makers, teacher training managers, and education researchers. © 2008-2011 IEEE.

摘要：
教师工作坊为校际间教师的协同研修提供了良好的平台,是促进教师专业发展的主要方式之一.该文针对教师工作坊研修过程中难以进行有效监测和及时指导的问题,利用学员研讨产生的交互式文本数据,提出了一种教师工作坊中学员话题挖掘方法.该方法利用内容语义分析法对学员评论反思内容进行整体分析;运用LDA模型自动挖掘不同类型学员发表的评论中的隐含话题和跟踪学员热点话题演化趋势.论文以典型的教师工作坊为例进行实验,实验结果表明:学员们能围绕研修主题进行讨论;相比普通学员,成绩优秀学员在学习态度上更显主动;如在多媒体、微课的技术应用等方面有着更深的认识和理解;而有关"技术支持的总结与复习"和"技术支持的教学评价"的话题并没有出现.话题演化趋势的实时反馈可视化分析,为引导研修活动深化发展提供了重要支持;也为教师工作坊的学习分析提供了一些可借鉴的思路.

针对网络学习空间中的数据未能被充分挖掘和利用的问题,文章提出了一种基于数据挖掘技术的在线学习行为分析模型。该模型将网络学习空间中的在线学习行为分为四类：独立学习行为、系统交互行为、资源交互行为和社会交互行为。基于此四类行为,该模型提出了相关分析、分类分析和聚类分析的分析方法,依据分析结果为网络学习中的各类利益相关者提供教学参考。文章以某网络学习空间数据为例,进行案例研究后发现：（1）独立学习行为与学习成绩的相关性最强,具有较强的预测作用;学习者的求助次数与其它因素相关性最弱,不宜作为行为分析的核心指标;（2）以具有较强相关性的学习行为对成绩进行预测,使用K-近邻分类器可获得84.62%的准确率;（3）对学习行为进行聚类分析,可发现学习者主要存在四种不同的学习行为模式,针对不同类型的学习者,教师可采取不同的干预策略,实现个性化的教与学。
