Beyond failure: the 2nd LAK Failathon 超越失败:第二届LAK失败马拉松
D. Clow, Rebecca Ferguson, Kirsty Kitto, Y. Cho, Mike Sharkey, C. Aguerrebere
The 2nd LAK Failathon will build on the successful event in 2016 and extend the workshop beyond discussing individual experiences of failure to exploring how the field can improve, particularly regarding the creation and use of evidence. Failure in research is an increasingly hot topic, with high-profile crises of confidence in the published research literature in medicine and psychology. Among the major factors in this research crisis are the many incentives to report and publish only positive findings. These incentives prevent the field in general from learning from negative findings, and almost entirely preclude the publication of mistakes and errors. Thus providing an alternative forum for practitioners and researchers to learn from each other's failures can be very productive. The first LAK Failathon, held in 2016, provided just such an opportunity for researchers and practitioners to share their failures and negative findings in a lower-stakes environment, to help participants learn from each other's mistakes. It was very successful, and there was strong support for running it as an annual event. This workshop will build on that success, with twin objectives to provide an environment for individuals to learn from each other's failures, and also to co-develop plans for how we as a field can better build and deploy our evidence base.
第二届LAK失败马拉松将以2016年成功举办的活动为基础,将研讨会从讨论个人失败经验扩展到探索该领域如何改进,特别是在证据的创建和使用方面。研究失败是一个越来越热门的话题,在医学和心理学领域发表的研究文献中出现了备受瞩目的信心危机。在这场研究危机的主要因素中,有许多动机只报道和发表积极的发现。这些动机一般阻止了该领域从消极的发现中学习,并且几乎完全排除了错误和错误的发表。因此,为从业者和研究人员提供一个从彼此的失败中学习的替代论坛是非常有成效的。2016年举办的第一届LAK Failathon为研究人员和从业者提供了这样一个机会,让他们在一个低风险的环境中分享他们的失败和负面发现,帮助参与者从彼此的错误中吸取教训。它非常成功,并且得到了每年举办一次的强烈支持。本次研讨会将以这一成功为基础,有两个目标,一是为个人提供一个从彼此的失败中学习的环境,二是共同制定我们作为一个领域如何更好地建立和部署我们的证据基础的计划。

Using learning analytics to explore help-seeking learner profiles in MOOCs 使用学习分析来探索mooc中寻求帮助的学习者概况
L. Corrin, P. D. Barba, Aneesha Bakharia
In online learning environments, learners are often required to be more autonomous in their approach to learning. In scaled online learning environments, like Massive Open Online Courses (MOOCs), there are differences in the ability of learners to access teachers and peers to get help with their study than in more traditional educational environments. This exploratory study examines the help-seeking behaviour of learners across several MOOCs with different audiences and designs. Learning analytics techniques (e.g., dimension reduction with t-sne and clustering with affinity propagation) were applied to identify clusters and determine profiles of learners on the basis of their help-seeking behaviours. Five help-seeking learner profiles were identified which provide an insight into how learners' help-seeking behaviour relates to performance. The development of a more in-depth understanding of how learners seek help in large online learning environments is important to inform the way support for learners can be incorporated into the design and facilitation of online courses delivered at scale.
在在线学习环境中,学习者通常需要在学习方法上更加自主。在大规模在线开放课程(MOOCs)等大规模在线学习环境中,与传统教育环境相比,学习者向教师和同伴寻求学习帮助的能力存在差异。本探索性研究考察了不同受众和设计的mooc学习者的求助行为。学习分析技术(例如,使用t-sne的降维和使用亲和传播的聚类)被应用于识别聚类,并根据学习者的求助行为确定学习者的概况。五个寻求帮助的学习者档案被确定,提供了一个洞察学习者的寻求帮助的行为如何与表现。更深入地了解学习者如何在大型在线学习环境中寻求帮助,对于将对学习者的支持纳入大规模在线课程的设计和促进方式具有重要意义。

Put your thinking cap on: detecting cognitive load using EEG during learning 戴上你的思考帽:在学习过程中使用脑电图检测认知负荷
Caitlin Mills, Igor Fridman, W. Soussou, Disha Waghray, A. Olney, S. D’Mello
Current learning technologies have no direct way to assess students' mental effort: are they in deep thought, struggling to overcome an impasse, or are they zoned out? To address this challenge, we propose the use of EEG-based cognitive load detectors during learning. Despite its potential, EEG has not yet been utilized as a way to optimize instructional strategies. We take an initial step towards this goal by assessing how experimentally manipulated (easy and difficult) sections of an intelligent tutoring system (ITS) influenced EEG-based estimates of students' cognitive load. We found a main effect of task difficulty on EEG-based cognitive load estimates, which were also correlated with learning performance. Our results show that EEG can be a viable source of data to model learners' mental states across a 90-minute session.
目前的学习技术没有直接的方法来评估学生的精神努力:他们是在深思熟虑,努力克服僵局,还是走神?为了解决这一挑战,我们建议在学习过程中使用基于脑电图的认知负荷检测器。尽管具有潜力,脑电图尚未被用作优化教学策略的一种方法。我们通过评估智能辅导系统(ITS)的实验操作(简单和困难)部分如何影响基于脑电图的学生认知负荷估计,向这一目标迈出了第一步。我们发现任务难度对基于脑电图的认知负荷估计有主要影响,这也与学习表现相关。我们的研究结果表明,脑电图可以作为一个可行的数据来源来模拟学习者在90分钟的学习过程中的心理状态。

Reflective writing analytics for actionable feedback 为可操作的反馈提供反思性写作分析
A. Gibson, A. Aitken, Ágnes Sándor, S. B. Shum, Cherie Tsingos-Lucas, Simon Knight
Reflective writing can provide a powerful way for students to integrate professional experience and academic learning. However, writing reflectively requires high quality actionable feedback, which is time-consuming to provide at scale. This paper reports progress on the design, implementation, and validation of a Reflective Writing Analytics platform to provide actionable feedback within a tertiary authentic assessment context. The contributions are: (1) a new conceptual framework for reflective writing; (2) a computational approach to modelling reflective writing, deriving analytics, and providing feedback; (3) the pedagogical and user experience rationale for platform design decisions; and (4) a pilot in a student learning context, with preliminary data on educator and student acceptance, and the extent to which we can evidence that the software provided actionable feedback for reflective writing.
反思性写作可以为学生提供整合专业经验和学术学习的有力途径。然而,反思性写作需要高质量的可操作反馈,而大规模提供这种反馈是很耗时的。本文报告了反思性写作分析平台的设计、实现和验证的进展,以在第三级真实评估环境中提供可操作的反馈。贡献有:(1)反思性写作的新概念框架;(2)一种计算方法来模拟反思性写作,推导分析并提供反馈;(3)平台设计决策的教学和用户体验理论基础;(4)在学生学习环境中进行试点,提供关于教育者和学生接受程度的初步数据,以及我们可以证明该软件为反思性写作提供可操作反馈的程度。

Implementing predictive learning analytics on a large scale: the teacher's perspective 大规模实施预测性学习分析:教师的视角
C. Herodotou, B. Rienties, Avinash Boroowa, Z. Zdráhal, Martin Hlosta, G. Naydenova
In this paper, we describe a large-scale study about the use of predictive learning analytics data with 240 teachers in 10 modules at a distance learning higher education institution. The aim of the study was to illuminate teachers' uses and practices of predictive data, in particular identify how predictive data was used to support students at risk of not completing or failing a module. Data were collected from statistical analysis of 17,033 students' performance by the end of the intervention, teacher usage statistics, and five individual semi-structured interviews with teachers. Findings revealed that teachers endorse the use of predictive data to support their practice yet in diverse ways and raised the need for devising appropriate intervention strategies to support students at risk.
在本文中,我们描述了一项关于使用预测学习分析数据的大规模研究,该研究涉及一家远程教育高等教育机构的10个模块的240名教师。该研究的目的是阐明教师对预测数据的使用和实践,特别是确定如何使用预测数据来支持有可能无法完成或不及格的学生。数据收集自17,033名学生在干预结束时的表现统计分析,教师使用统计数据以及五次对教师的半结构化访谈。调查结果显示,教师支持使用预测数据以不同的方式支持他们的实践,并提出需要制定适当的干预策略来支持有风险的学生。

Learning pulse: a machine learning approach for predicting performance in self-regulated learning using multimodal data 学习脉冲:一种机器学习方法,用于使用多模态数据预测自我调节学习的性能
D. D. Mitri, Maren Scheffel, H. Drachsler, D. Börner, Stefaan Ternier, M. Specht
Learning Pulse explores whether using a machine learning approach on multimodal data such as heart rate, step count, weather condition and learning activity can be used to predict learning performance in self-regulated learning settings. An experiment was carried out lasting eight weeks involving PhD students as participants, each of them wearing a Fitbit HR wristband and having their application on their computer recorded during their learning and working activities throughout the day. A software infrastructure for collecting multimodal learning experiences was implemented. As part of this infrastructure a Data Processing Application was developed to pre-process, analyse and generate predictions to provide feedback to the users about their learning performance. Data from different sources were stored using the xAPI standard into a cloud-based Learning Record Store. The participants of the experiment were asked to rate their learning experience through an Activity Rating Tool indicating their perceived level of productivity, stress, challenge and abilities. These self-reported performance indicators were used as markers to train a Linear Mixed Effect Model to generate learner-specific predictions of the learning performance. We discuss the advantages and the limitations of the used approach, highlighting further development points.
《学习脉动》探讨了在多模态数据(如心率、步数、天气状况和学习活动)上使用机器学习方法是否可以用于预测自我调节学习环境中的学习表现。研究人员进行了一项为期八周的实验,让博士生作为参与者,每个人都戴着Fitbit人力资源腕带,并在他们全天的学习和工作活动中记录他们在电脑上的应用程序。实现了用于收集多模式学习经验的软件基础结构。作为该基础设施的一部分,开发了一个数据处理应用程序,用于预处理,分析和生成预测,以向用户提供有关其学习表现的反馈。来自不同来源的数据使用xAPI标准存储到基于云的学习记录存储中。实验参与者被要求通过一个活动评级工具对他们的学习经历进行评级,该工具显示了他们对生产力、压力、挑战和能力的感知水平。这些自我报告的绩效指标被用作标记来训练线性混合效应模型,以生成学习者特定的学习绩效预测。我们讨论了所使用方法的优点和局限性,并强调了进一步的发展要点。

What does student writing tell us about their thinking on social justice? 学生的写作告诉我们他们对社会正义的看法是什么?
Heeryung Choi, Christopher A. Brooks, Kevyn Collins-Thompson
In this work we investigate the use of deep learning for text analysis to measure elements of student thinking related to issues of privilege, oppression, diversity and social justice. We leverage historical expert annotations as well as a large lexical model to create a more generalizable vocabulary for identifying these characteristics in short student writing. We demonstrate the feasibility of this approach, and identify further areas for research.
在这项工作中,我们研究了使用深度学习进行文本分析,以衡量与特权、压迫、多样性和社会正义问题相关的学生思维元素。我们利用历史专家注释和一个大型词汇模型来创建一个更通用的词汇表,以识别学生短文中的这些特征。我们证明了这种方法的可行性,并确定了进一步的研究领域。

Buying time: enabling learners to become earners with a real-world paid task recommender system 购买时间:通过现实世界的付费任务推荐系统,使学习者成为赚钱者
Guanliang Chen, Dan Davis, Markus Krause, C. Hauff, G. Houben
Massive Open Online Courses (MOOCs) aim to educate the world, especially learners from developing countries. While MOOCs are certainly available to the masses, they are not yet fully accessible. Although all course content is just clicks away, deeply engaging with a MOOC requires a substantial time commitment, which frequently becomes a barrier to success. To mitigate the time required to learn from a MOOC, we here introduce a design that enables learners to earn money by applying what they learn in the course to real-world marketplace tasks. We present a Paid Task Recommender System (Rec-$ys), which automatically recommends course-relevant tasks to learners as drawn from online freelance platforms. Rec-$ys has been deployed into a data analysis MOOC and is currently under evaluation.
大规模在线开放课程(MOOCs)旨在教育全世界,尤其是来自发展中国家的学习者。虽然mooc当然对大众开放,但它们还没有完全开放。尽管所有课程内容只需点击鼠标即可获得,但深入学习MOOC需要投入大量时间,这往往成为成功的障碍。为了减少从MOOC中学习所需的时间,我们在这里介绍了一种设计,使学习者能够通过将他们在课程中学到的知识应用到现实世界的市场任务中来赚钱。我们提出了一个付费任务推荐系统(Rec-$ys),它自动从在线自由平台向学习者推荐与课程相关的任务。Rec-$ys已被部署到数据分析MOOC中,目前正在进行评估。

Supporting collaborative learning with tag recommendations: a real-world study in an inquiry-based classroom project 用标签推荐支持协作学习:一个基于探究的课堂项目中的真实世界研究
Simone Kopeinik, E. Lex, Paul Seitlinger, D. Albert, Tobias Ley
In online social learning environments, tagging has demonstrated its potential to facilitate search, to improve recommendations and to foster reflection and learning.Studies have shown that shared understanding needs to be established in the group as a prerequisite for learning. We hypothesise that this can be fostered through tag recommendation strategies that contribute to semantic stabilization. In this study, we investigate the application of two tag recommenders that are inspired by models of human memory: (i) the base-level learning equation BLL and (ii) Minerva. BLL models the frequency and recency of tag use while Minerva is based on frequency of tag use and semantic context. We test the impact of both tag recommenders on semantic stabilization in an online study with 56 students completing a group-based inquiry learning project in school. We find that displaying tags from other group members contributes significantly to semantic stabilization in the group, as compared to a strategy where tags from the students' individual vocabularies are used. Testing for the accuracy of the different recommenders revealed that algorithms using frequency counts such as BLL performed better when individual tags were recommended. When group tags were recommended, the Minerva algorithm performed better. We conclude that tag recommenders, exposing learners to each other's tag choices by simulating search processes on learners' semantic memory structures, show potential to support semantic stabilization and thus, inquiry-based learning in groups.
在在线社交学习环境中,标签已经证明了它在促进搜索、改进推荐和促进反思和学习方面的潜力。研究表明,作为学习的先决条件,需要在群体中建立共同的理解。我们假设这可以通过有助于语义稳定的标签推荐策略来促进。在本研究中,我们研究了受人类记忆模型启发的两个标签推荐器的应用:(i)基础学习方程BLL和(ii) Minerva。BLL对标签使用的频率和频率进行建模,而Minerva则基于标签使用的频率和语义上下文。我们在一项在线研究中测试了这两种标签推荐对语义稳定的影响,该研究有56名学生在学校完成了一个基于小组的研究性学习项目。我们发现,与使用来自学生个人词汇表的标签的策略相比,显示来自其他小组成员的标签对小组的语义稳定有显著的贡献。对不同推荐器的准确性测试表明,当单个标签被推荐时,使用频率计数(如BLL)的算法表现更好。当推荐组标记时,Minerva算法表现更好。我们得出的结论是,标签推荐器通过模拟学习者语义记忆结构的搜索过程,让学习者接触到彼此的标签选择,显示出支持语义稳定的潜力,从而支持群体中基于探究式的学习。

We conclude that tag recommenders, exposing learners to each other's tag choices by simulating search processes on learners' semantic memory structures, show potential to support semantic stabilization and thus, inquiry-based learning in groups.","PeriodicalId":160897,"journal":{"name":"Proceedings of the Seventh International Learning Analytics & Knowledge Conference","volume":"43 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133846621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Person-centered approach to explore learner's emotionality in learning within a 3D narrative game 以人为本的方法在三维叙事游戏中探索学习者的学习情绪
Zhenhua Xu, Earl Woodruff
Emotions form an integral part of our cognitive function. Past research has demonstrated conclusive associations between emotions and learning achievement [7, 26, 27]. This paper used a person-centered approach to explore students' (N = 65) facial behavior, emotions, learner traits and learning. An automatic facial expression recognition system was used to detect both middle school and university students' real-time facial movements while they learned scientific tasks in a 3D narrative video game. The results indicated a strong statistical relationship between three specific facial movements (i.e., outer brow raising, lip tightening and lip pressing), student self-regulatory learning strategy and learning performance. Outer brow raising (AU2) had strong predictive power when a student is confronted with obstacles and does not know how to proceed. Both lip tightening and pressing (AU23 and AU24) were predictive when a student engaged in a task that requires a deep level of incoming information processing and short memory activation. The findings also suggested a correlational relationship between student self-regulatory learning strategy use and neutral state. It is hoped that this study will provide empirical evidence for helping us develop a deeper understanding of the relationship between facial behavior and complex learning especially in educational games.
情绪是我们认知功能的一个组成部分。过去的研究已经证明情绪与学习成绩之间存在确凿的联系[7,26,27]。本文采用以人为本的方法对学生(N = 65)的面部行为、情绪、学习者特征和学习进行了研究。一个自动面部表情识别系统被用来检测中学生和大学生在3D叙事视频游戏中学习科学任务时的实时面部动作。结果表明,三种特定的面部动作(即外眉、紧唇和压唇)与学生自我调节学习策略和学习成绩之间存在显著的统计学关系。当学生遇到障碍不知道如何前进时,外眉抬高(AU2)具有很强的预测能力。当学生从事一项需要深度信息处理和短期记忆激活的任务时,抿紧嘴唇和压紧嘴唇(AU23和AU24)都可以预测。研究结果还表明,学生自我调节学习策略的使用与中性状态之间存在相关关系。希望本研究能够提供经验证据,帮助我们更深入地理解面部行为与复杂学习之间的关系,特别是在教育游戏中。
