Embedding mobile learning into everyday life settings

The increasing ubiquity of smartphones has changed the way we interact with information and acquire new knowledge. The prevalence of personal mobile devices in our everyday lives creates new opportunities for learning that exceed the narrow boundaries of a school’s classroom and provide the foundations for lifelong learning. Learning can now happen whenever and wherever we are; whether on the sofa at home, on the bus during our commute, or on a break at work. However, the flexibility offered by mobile learning also creates its challenges. Being able to learn anytime and anywhere does not necessarily result in learning uptake. Without the school environment’s controlled schedule and teacher guidance, the learners must actively initiate learning activities, keep up repetition schedules, and cope with learning in interruption-prone everyday environments. Both interruptions and infrequent repetition can harm the learning process and long-term memory retention. We argue that current mobile learning applications insufficiently support users in coping with these challenges. In this thesis, we explore how we can utilize the ubiquity of mobile devices to ensure frequent engagement with the content, focusing primarily on language learning and supporting users in dealing with learning breaks and interruptions. Following a user-centered design approach, we first analyzed mobile learning behavior in everyday settings. Based on our findings, we proposed concepts and designs, developed research prototypes, and evaluated them in laboratory and field evaluations with a specific focus on user experience. To better understand users’ learning behavior with mobile devices, we first characterized their interaction with mobile learning apps through a detailed survey and a diary study. Both methods confirmed the enormous diversity in usage situations and preferences. We observed that learning often happens unplanned, infrequently, among the company of friends or family, or while simultaneously performing secondary tasks such as watching TV or eating. The studies further uncovered a significant prevalence of interruptions in everyday settings that affected users’ learning behavior, often leading to suspension and termination of the learning activities. We derived design implications to support learning in diverse situations, particularly aimed at mitigating the adverse effects of multitasking and interruptions. The proposed strategies should help designers and developers create mobile learning applications that adapt to the opportunities and challenges of learning in everyday mobile settings. We explored four main challenges, emphasizing that (1) we need to consider that Learning in Everyday Settings is Diverse and Interruption-prone, (2) learning performance is affected by Irregular and Infrequent Practice Behavior, (3) we need to move From Static to Personalized Learning, and (4) that Interruptions and Long Learning Breaks can Negatively Affect Performance. To tackle these challenges, we propose to embed learning into everyday smartphone interactions, which could foster frequent engagement with – and implicitly personalize – learning content (according to users’ interests and skills). Further, we investigate how memory cues could be applied to support task resumption after interruptions in mobile learning. To confirm that our idea of embedding learning into everyday interactions can increase exposure, we developed an application integrating learning tasks into the smartphone authentication process. Since unlocking the smartphone is a frequently performed action without any other purpose, our subjects appreciated the idea of utilizing this process to perform quick and simple learning interactions. Evidence from a comparative user study showed that embedding learning tasks into the unlocking mechanism led to significantly more interactions with the learning content without impairing the learning quality. We further explored a method for embedding language comprehension assessment into users’ digital reading and listening activities. By applying physiological measurements as implicit input, we reliably detected unknown words during laboratory evaluations. Identifying such knowledge gaps could be used for the provision of in-situ support and to inform the generation of personalized language learning content tailored to users’ interests and proficiency levels. To investigate memory cueing as a concept to support task resumption after interruptions, we complemented a theoretical literature analysis of existing applications with two research probes implementing and evaluating promising design concepts. We showed that displaying memory cues when the user resumes the learning activity after an interruption improves their subjective user experience. A subsequent study presented an outlook on the generalizability of memory cues beyond the narrow use case of language learning. We observed that the helpfulness of memory cues for reflecting on prior learning is highly dependent on the design of the cues, particularly the granularity of the presented information. We consider interactive cues for specific memory reactivation (e.g., through multiple-choice questions) a promising scaffolding concept for connecting individual micro-learning sessions when learning in everyday settings. The tools and applications described in this thesis are a starting point for designing applications that support learning in everyday settings. We broaden the understanding of learning behavior and highlight the impact of interruptions in our busy everyday lives. While this thesis focuses mainly on language learning, the concepts and methods have the potential to be generalized to other domains, such as STEM learning. We reflect on the limitations of the presented concepts and outline future research perspectives that utilize the ubiquity of mobile devices to design mobile learning interactions for everyday settings.Die Allgegenwärtigkeit von Smartphones verändert die Art und Weise wie wir mit Informationen umgehen und Wissen erwerben. Die weite Verbreitung von mobilen Endgeräten in unserem täglichen Leben führt zu neuen Möglichkeiten des Lernens, welche über die engen Grenzen eines Klassenraumes hinausreichen und das Fundament für lebenslanges Lernen schaffen. Lernen kann nun zu jeder Zeit und an jedem Ort stattfinden: auf dem Sofa Zuhause, im Bus während des Pendelns oder in der Pause auf der Arbeit. Die Flexibilität des mobilen Lernens geht jedoch zeitgleich mit Herausforderungen einher. Ohne den kontrollierten Ablaufplan und die Unterstützung der Lehrpersonen im schulischen Umfeld sind die Lernenden selbst dafür verantwortlich, aktiv Lernsitzungen zu initiieren, Wiederholungszyklen einzuhalten und Lektionen in unterbrechungsanfälligen Alltagssituationen zu meistern. Sowohl Unterbrechungen als auch unregelmäßige Wiederholung von Inhalten können den Lernprozess behindern und der Langzeitspeicherung der Informationen schaden. Wir behaupten, dass aktuelle mobile Lernanwendungen die Nutzer*innen nur unzureichend in diesen Herausforderungen unterstützen. In dieser Arbeit erforschen wir, wie wir uns die Allgegenwärtigkeit mobiler Endgeräte zunutze machen können, um zu erreichen, dass Nutzer*innen regelmäßig mit den Lerninhalten interagieren. Wir fokussieren uns darauf, sie im Umgang mit Unterbrechungen und Lernpausen zu unterstützen. In einem nutzerzentrierten Designprozess analysieren wir zunächst das Lernverhalten auf mobilen Endgeräten in alltäglichen Situationen. Basierend auf den Erkenntnissen schlagen wir Konzepte und Designs vor, entwickeln Forschungsprototypen und werten diese in Labor- und Feldstudien mit Fokus auf User Experience (wörtl. “Nutzererfahrung”) aus. Um das Lernverhalten von Nutzer*innen mit mobilen Endgeräten besser zu verstehen, versuchen wir zuerst die Interaktionen mit mobilen Lernanwendungen durch eine detaillierte Umfrage und eine Tagebuchstudie zu charakterisieren. Beide Methoden bestätigen eine enorme Vielfalt von Nutzungssituationen und -präferenzen. Wir beobachten, dass Lernen oft ungeplant, unregelmäßig, im Beisein von Freunden oder Familie, oder während der Ausübung anderer Tätigkeiten, beispielsweise Fernsehen oder Essen, stattfindet. Die Studien decken zudem Unterbrechungen in Alltagssituationen auf, welche das Lernverhalten der Nutzer*innen beeinflussen und oft zum Aussetzen oder Beenden der Lernaktivität führen. Wir leiten Implikationen ab, um Lernen in vielfältigen Situationen zu unterstützen und besonders die negativen Einflüsse von Multitasking und Unterbrechungen abzuschwächen. Die vorgeschlagenen Strategien sollen Designer*innen und Entwickler*innen helfen, mobile Lernanwendungen zu erstellen, welche sich den Möglichkeiten und Herausforderungen von Lernen in Alltagssituationen anpassen. Wir haben vier zentrale Herausforderungen identifiziert: (1) Lernen in Alltagssituationen ist divers und anfällig für Unterbrechungen; (2) Die Lerneffizienz wird durch unregelmäßiges Wiederholungsverhalten beeinflusst; (3) Wir müssen von statischem zu personalisiertem Lernen übergehen; (4) Unterbrechungen und lange Lernpausen können dem Lernen schaden. Um diese Herausforderungen anzugehen, schlagen wir vor, Lernen in alltägliche Smartphoneinteraktionen einzubetten. Dies führt zu einer vermehrten Beschäftigung mit Lerninhalten und könnte zu einer impliziten Personalisierung von diesen anhand der Interessen und Fähigkeiten der Nutzer*innen beitragen. Zudem untersuchen wir, wie Memory Cues (wörtl. “Gedächtnishinweise”) genutzt werden können, um das Fortsetzen von Aufgaben nach Unterbrechungen im mobilen Lernen zu erleichtern. Um zu zeigen, dass unsere Idee des Einbettens von Lernaufgaben in alltägliche Interaktionen wirklich die Beschäftigung mit diesen erhöht, haben wir eine Anwendung entwickelt, welche Lernaufgaben in den Entsperrprozess von Smartphones integriert. Da die Authentifizierung auf dem Mobilgerät eine häufig durchgeführte Aktion ist, welche keinen weiteren Mehrwert bietet, begrüßten unsere Studienteilnehmenden die Idee, den Prozess für die Durchführung kurzer und einfacher Lerninteraktionen zu nutzen. Ergebnisse aus einer vergleichenden Nutzerstudie haben gezeigt, dass die Einbettung von Aufgaben in den Entsperrprozess zu signifikant mehr Interaktionen mit den Lerninhalten führt, ohne dass die Lernqualität beeinträchtigt wird. Wir haben außerdem eine Methode untersucht, welche die Messung von Sprachverständnis in die digitalen Lese- und Höraktivitäten der Nutzer*innen einbettet. Mittels physiologischer Messungen als implizite Eingabe können wir in Laborstudien zuverlässig unbekannte Wörter erkennen. Die Aufdeckung solcher Wissenslücken kann genutzt werden, um in-situ Untestützung bereitzustellen und um personalisierte Lerninhalte zu generieren, welche auf die Interessen und das Wissensniveau der Nutzer*innen zugeschnitten sind. Um Memory Cues als Konzept für die Unterstützung der Aufgabenfortsetzung nach Unterbrechungen zu untersuchen, haben wir eine theoretische Literaturanalyse von bestehenden Anwendungen um zwei Forschungsarbeiten erweitert, welche vielversprechende Designkonzepte umsetzen und evaluieren. Wir haben gezeigt, dass die Präsentation von Memory Cues die subjektive User Experience verbessert, wenn der Nutzer die Lernaktivität nach einer Unterbrechung fortsetzt. Eine Folgestudie stellt einen Ausblick auf die Generalisierbarkeit von Memory Cues dar, welcher über den Tellerrand des Anwendungsfalls Sprachenlernen hinausschaut. Wir haben beobachtet, dass der Nutzen von Memory Cues für das Reflektieren über gelernte Inhalte stark von dem Design der Cues abhängt, insbesondere von der Granularität der präsentierten Informationen. Wir schätzen interaktive Cues zur spezifischen Gedächtnisaktivierung (z.B. durch Mehrfachauswahlfragen) als einen vielversprechenden Unterstützungsansatz ein, welcher individuelle Mikrolerneinheiten im Alltag verknüpfen könnte. Die Werkzeuge und Anwendungen, die in dieser Arbeit beschrieben werden, sind ein Startpunkt für das Design von Anwendungen, welche das Lernen in Alltagssituationen unterstützen. Wir erweitern das Verständnis, welches wir von Lernverhalten im geschäftigen Alltagsleben haben und heben den Einfluss von Unterbrechungen in diesem hervor. Während sich diese Arbeit hauptsächlich auf das Lernen von Sprachen fokussiert, haben die vorgestellten Konzepte und Methoden das Potential auf andere Bereiche übertragen zu werden, beispielsweise das Lernen von MINT Themen. Wir reflektieren über die Grenzen der präsentierten Konzepte und skizzieren Perspektiven für zukünftige Forschungsarbeiten, welche sich die Allgegenwärtigkeit von mobilen Endgeräten zur Gestaltung von Lernanwendungen für den Alltag zunutze machen

Designing intelligent support for learning from and in everyday contexts

Motivation and engagement in learning benefit from a good match of learning settings and materials to individual learner contexts. This includes intrinsic context factors such as prior knowledge and personal interests but also extrinsic factors such as the current environment. Recent developments in adaptive and intelligent technology enable the personalisation of context-aware learning. For example, computer vision algorithms, machine translation, and Augmented Reality make it possible to support the creation of meaningful connections between learners and their context. However, for successful adoption in everyday life, these technologies also need to consider the learner experience. This thesis investigates the design of personalised context-aware learning experiences through the lens of ubiquitous and self-directed language learning as a multi-faceted learning domain. Specifically, it presents and discusses the design, implementation, and evaluation of technology support for learning in and from learners’ everyday contexts with a strong focus on the learner perspective and user experience. The work is guided by four different roles that technology can take on in context-aware ubiquitous learning: For enhancing learning situations, it can (1) sense and (2) trigger in learners’ everyday contexts. For enhancing learning contents, it can (3) augment activities and (4) generate learning material from learner everyday contexts. With regards to the sensing role, the thesis investigates how learners typically use mobile learning apps in everyday contexts. Activity and context logging, combined with experience sampling, confirm that mobile learning sessions spread across the day and occur in different settings. However, they are typically short and frequently interrupted. This indicates that learners may benefit from better integrating learning into everyday contexts, e.g. by supporting task resumption. Subsequently, we explore how this integration could be supported with intelligent triggers linked to opportune moments for learning. We conceptualise and evaluate different trigger types based on interaction patterns and context detection. Our findings show that simple interactions (e.g. plugging in headphones) are promising for capturing both availability and willingness to engage in a learning activity. We discuss how similar interaction triggers could be adapted to match individual habits. In the area of enhancing learning contents, we first investigate how enjoyable everyday activities could be augmented for learning without disrupting these activities. Specifically, we assess the learner experience with interactive grammar support in e-readers and adapted captions for audio-visual media. Participants in our studies felt that the learning augmentations successfully supported their learning process. The information load of the learning support should match the learners’ current needs to maintain the activity flow. Learners may need encouragement to opt for novel concepts optimised for learning (e.g. time-synchronised captions) rather than sticking to habits (e.g. standard captions). Next, the thesis explores learner needs and preferences in generating their own personalised learning material from their context. We design and evaluate automated content generation methods that generate learning opportunities from objects in the learner’s environment. The connection to the learner’s context is established with state-of-the-art technology, such as object detection and Augmented Reality. Through several user studies, we show that learning performance and engagement with auto-generated personalised learning material is comparable to predefined and manually generated content. Findings further indicate that the success of personalisation depends on the effort required to generate content and whether the generation results match the learner’s expectations. Through the different perspectives examined in this thesis, we provide new insights into challenges and opportunities that we synthesise in a framework for context-aware ubiquitous learning technology. The findings also have more general implications for the interaction design of personalised and context-aware intelligent systems. Notably, for the auto-generation of personalised content, it is essential to consider not only correctness from a technological perspective but also how users may perceive the results.Lernmotivation und Engagement profitieren davon, wenn Lernumgebungen und Lernmaterialien auf den individuellen Kontext der Lernenden abgestimmt sind. Dieser umfasst sowohl intrinsische Faktoren wie Vorkenntnisse und persönliche Interessen, aber auch extrinsische Faktoren wie die aktuelle Umgebung. Aktuelle Weiterentwicklungen im Bereich adaptiver und intelligenter Technologien ermöglichen es, Lernen kontextbewusst zu personalisieren. So können mithilfe von Computer-Vision-Algorithmen, maschineller Übersetzung und Augmented Reality sinnvolle Verknüpfungen zwischen Lernenden und ihrem Kontext geschaffen werden. Allerdings müssen diese Technologien für einen erfolgreichen Einsatz im Alltag auch die Lernerfahrung mit einbeziehen. Diese Arbeit untersucht die Gestaltung personalisierter kontextbewusster Lernerfahrungen aus der Perspektive des ubiquitären und self-directed Learning im Sprachenlernen, einem vielseitigen Lernbereich. Insbesondere wird die Konzeption, Implementierung und Evaluierung von Technologieunterstützung für das Sprachenlernen in und aus dem Alltagskontext der Lernenden vorgestellt und diskutiert, wobei der Schwerpunkt auf der Perspektive der Lernenden und der Nutzererfahrung liegt. Die Arbeit orientiert sich an vier verschiedenen Rollen, die Technologie im kontextbewussten Lernen einnehmen kann. Um Lernsituationen anzureichern, kann Technologie im Alltagskontext von Lernenden (1) erfassen und (2) auslösen. Um Lerninhalte anzureichern, kann Technologie aus dem Alltagskontext (3) Aktivitäten augmentieren und (4) Inhalte generieren. Im Hinblick auf die erfassende Rolle von Technologie wird in dieser Arbeit untersucht, wie die Lernenden mobile Lern-Apps in alltäglichen Kontexten nutzen. Die Aufzeichnung von Aktivitäten und Kontexten in Kombination mit Experience Sampling bestätigt, dass Lerneinheiten im mobilen Lernen über den Tag verteilt sind und in verschiedenen Umgebungen stattfinden. Allerdings sind sie in der Regel kurz und werden häufig unterbrochen. Dies deutet darauf hin, dass die Lernenden von einer besseren Integration des Lernens in ihren Alltagskontext profitieren könnten, z. B. durch Unterstützung des Wiedereinstiegs nach einer Unterbrechung. Anschließend untersuchen wir, wie diese Integration durch intelligente Trigger unterstützt werden könnte, die mit passenden Lernzeitpunkten verknüpft sind. Wir konzipieren und evaluieren verschiedene Arten von Triggern auf Basis von Interaktionsmustern und Kontexterkennung. Unsere Ergebnisse zeigen, dass einfache Interaktionen (z. B. das Einstecken von Kopfhörern) vielversprechend dafür sind, sowohl die Verfügbarkeit als auch die Bereitschaft für eine Lernaktivität zu erfassen. Wir diskutieren, wie ähnliche Interaktionstrigger an individuelle Gewohnheiten angepasst werden können. Im Bereich der Augmentierung von Lerninhalten untersuchen wir zunächst, wie unterhaltsame Alltagsaktivitäten für das Lernen aufbereitet werden können, ohne diese Aktivitäten zu beeinträchtigen. Konkret bewerten wir die Lernerfahrung mit interaktiver Grammatikunterstützung in E-Readern und angepassten Untertiteln für audiovisuelle Medien. Die Teilnehmer:innen unserer Studien fanden, dass die Lernunterstützung ihren Lernprozess erfolgreich förderte. Die Informationslast im Lernsystem sollte auf die aktuellen Bedürfnisse der Lernenden angepasst werden, damit das Flow-Erlebnis nicht beeinträchtigt wird. Die Lernenden brauchen möglicherweise Ermutigung dafür, sich für neuartige, lernoptimierte Konzepte zu entscheiden (z. B. zeitsynchrone Untertitel), anstatt an Gewohnheiten festzuhalten (z. B. Standarduntertitel). Als Nächstes werden in dieser Arbeit die Bedürfnisse und Präferenzen der Lernenden bei der Erstellung ihres eigenen personalisierten Lernmaterials aus ihrem Kontext untersucht. Insbesondere werden Methoden zur automatischen Generierung von Inhalten entwickelt und evaluiert, die Lernmöglichkeiten aus Objekten in der Umgebung des Lernenden generieren. Die Verbindung zum Kontext des Lernenden wird durch aktuelle Technologien wie Objekterkennung und Augmented Reality hergestellt. Wir zeigen anhand mehrerer Nutzerstudien, dass die Lernleistung und das Engagement bei automatisch personalisiertem Lernmaterial mit vordefinierten und manuell erstellten Inhalten vergleichbar sind. Die Ergebnisse zeigen außerdem, dass der Erfolg der Personalisierung vom Aufwand abhängt, der für die Erstellung der Inhalte erforderlich ist, und davon, ob die generierten Materialien den Erwartungen der Lernenden entsprechen. Die verschiedenen Perspektiven, die in dieser Arbeit untersucht werden, bieten neue Einblicke in Herausforderungen und Möglichkeiten, die wir in einem Framework für kontextbewusste ubiquitäre Lerntechnologie zusammenfassen. Die Ergebnisse haben auch allgemeinere Auswirkungen auf die Gestaltung der Interaktion mit personalisierten und kontextbewussten intelligenten Systemen. Beispielsweise ist es bei der automatischen Generierung personalisierter Inhalte wichtig, nicht nur die Korrektheit aus technologischer Sicht zu berücksichtigen, sondern auch, wie die Nutzer die Ergebnisse wahrnehmen

The Effect of Interruptions on Primary Task Performance in Safety-Critical Environments

Safety critical systems in medicine utilize alarms to signal potentially life threatening situations to professionals and patients. In particular, in the medical field multiple alarms from equipment are activated daily and often simultaneously. There are a number of alarms which require caregivers to take breaks in complex, primary tasks to attend to the interruption task which is signaled by the alarm. The motivation for this research is the knowledge that, in general, interrupting tasks can have a potentially negative impact on performance and outcomes of the primary task. The focus of this research is on the effect of an interrupting task on the cognitive behavior of nurses on a primary task: administering medication to a simulated patient. Fifty-eight student nurses were monitored with eye-tracking technology as they perform direct patient care and a medication administration task. There are four hypotheses. First, it is hypothesized that an interruption generated by an alarm during medication administration significantly increases errors because it causes caregivers to forget components of the original task. These errors result when the primary task is suspended in memory, as a result of the intervening task, and because of this suspension, memory for the original task can decay. Second, it is hypothesized that interrupting tasks result in time delays on the primary task (the time during which the caregiver is performing the interrupting task is not included in the time to perform the original task). Third, it is hypothesized that metacognition training will mitigate the negative effects of the interrupting task on the primary task. The metacognition training is based on knowledge of how memory processes are affected by interruptions and how modifying these processes can potentially result in a reduction of errors. Fourth, it is hypothesized that the intervention strategy will lead to improvements in the memory for the material that is required to resume and complete the primary task. This improvement will be measured by increases in the number of eye fixations to the primary task before attending to the secondary task. Furthermore, this measurement will correlate with a reduction in errors

USE OF STAY S.A.F.E. STRATEGY DURING MEDICATION ADMINISTRATION IN REDUCING ERRORS

Healthcare related medical errors are the third leading cause of death in the United States. Interruptions and distractions can lead to an increased risk of nurses making errors in healthcare, particularly during medication administration. Student nurses should receive education during their prelicensure period on the management of interruptions especially before being given the responsibility of performing high risk tasks such as medication administration. Using a novel interruption management strategy called Stay S.A.F.E., nursing students were interrupted during a simulated medication administration. Students were evaluated on the time spent on the task and if errors were committed. Lastly, perceived workload was measured using the NASA Task Load Index (TLX) tool

Procedural-Reasoning Architecture for Applied Behavior Analysis-based Instructions

Autism Spectrum Disorder (ASD) is a complex developmental disability affecting as many as 1 in every 88 children. While there is no known cure for ASD, there are known behavioral and developmental interventions, based on demonstrated efficacy, that have become the predominant treatments for improving social, adaptive, and behavioral functions in children. Applied Behavioral Analysis (ABA)-based early childhood interventions are evidence based, efficacious therapies for autism that are widely recognized as effective approaches to remediation of the symptoms of ASD. They are, however, labor intensive and consequently often inaccessible at the recommended levels. Recent advancements in socially assistive robotics and applications of virtual intelligent agents have shown that children with ASD accept intelligent agents as effective and often preferred substitutes for human therapists. This research is nascent and highly experimental with no unifying, interdisciplinary, and integral approach to development of intelligent agents based therapies, especially not in the area of behavioral interventions. Motivated by the absence of the unifying framework, we developed a conceptual procedural-reasoning agent architecture (PRA-ABA) that, we propose, could serve as a foundation for ABA-based assistive technologies involving virtual, mixed or embodied agents, including robots. This architecture and related research presented in this disser- tation encompass two main areas: (a) knowledge representation and computational model of the behavioral aspects of ABA as applicable to autism intervention practices, and (b) abstract architecture for multi-modal, agent-mediated implementation of these practices

Redefining Attention (and Revamping the Legal Profession?) for the Digital Generation

With computers, text messages, Facebook, cell phones, smartphones, tablets, iPods, and other information and communication technologies (“ICTs”) constantly competing for our attention, we live in an age of perpetual distraction. Educators have long speculated that constant exposure to ICTs is eroding our ability to stay focused, and recent research supports these speculations. This raises particularly troubling implications for the practice of law, in which being able to pay sustained attention to the task at hand is crucial. Research also indicates that the brains of today’s young people, the “Digital Generation,” may function differently than the brains of their elders because the Digital Generation have grown up immersed in digital technology. This suggests that the techniques today’s legal professionals might use to cultivate attention in the face of technological distraction could prove to be inappropriate for future generations of lawyers. When the Digital Generation are both the attorneys and the clients, it may be the practice of law — rather than the lawyers — that needs to change. This paper explores the science of attention and explains why attention is important. Next, it introduces the Digital Generation and their relationship with digital technology. It then examines the connection between ICT exposure and attention and reviews several suggestions that others have made about how legal professionals should respond to the challenges ICTs pose to focused attention. This paper then takes the conversation in a new direction: It predicts ways in which the legal profession, rather than the legal professionals, will necessarily have to adapt to technology in the future. Finally, it offers thoughts about how the legal profession should view its relationship with technology going forward

The Use of the Social Skills Module Training to Teach Appropriate Communication Skills to a Student with Autism

The purpose of this study was to examine the effects of video modeling (VM) in order to improve conversational skills using on-line instructional modules, self-monitoring, modeling of socially appropriate skills, and provide coaching opportunities within a controlled setting to an adolescent with Autism Spectrum Disorder (ASD). Using an ABAB Reversal design, direct observations of the participant\u27s identified target behaviors were collected two times per week during a controlled setting. Overall, data demonstrated that the combined treatment package was effective for improving the frequency of targeted social skills for the participant, including an additional four sessions that were needed to assess acquisition of targeted skills due to the participant graduating from high school and going on a 2-week vacation. Generalization was provided to the participant throughout the study outside of the controlled setting. However, data collection was obtained and scored by the primary researcher and a trained graduate student. In addition to current research this study complements evidence that a combined intervention presented via computer may be a beneficial method for addressing social skill difficulties for individuals with ASD

Examining the Effect of Interruptions at Different Breakpoints and Frequencies Within a Task

Research on the effects of interruptions shows that they can be either costly or beneficial depending on which aspects of an interruption are manipulated. One important aspect that contributes to these conflicting results concerns when an interruption occurs. The present study explored how event segmentation theory (EST) can be used to determine optimal moments for an interruption relying on hierarchical task analysis (HTA) to identify coarse and fine event boundaries. Utilizing a 2 X 3 mixed design, undergraduate students completed a trip planning task divided into three task trials. The within-subjects factor was interruption timing, which had three levels: none, coarse breakpoints, and fine breakpoints. The between-subjects factor was interruption frequency, which had two levels: one and three. According to memory for goals theory (MFG), a task representation at a fine breakpoint is large and thus an interruption occurring at this breakpoint increases memory demand and results in performance decrements when compared to an interruption at a coarse breakpoint. In line with this theory, it was hypothesized that interruptions would be more disruptive at fine vs. coarse breakpoints and that as the frequency of interruptions increased, so would the degree of disruption. Last, it was expected that the effects of high frequency interruptions would be more pronounced at fine vs. coarse breakpoints. The dependent measures included resumption lag, task completion time, number of errors, mental workload, and frustration. The findings provided partial support for these predictions. Consistent with MFG theory and EST, participants took longer to resume the primary task and reported higher mental workload and frustration when interruptions occurred at fine breakpoints. Conversely, the effects of interruptions at coarse breakpoints were similar to completing the task without interruption. However, interruption frequency had no effect on performance. In general, these results suggest that the disruptiveness of a single or even a few interruptions is tied to the point within the task hierarchy where it occurs

Using new assessment tools during and post-COVID-19

This work tackles the need to evaluate and identify fresh assessment techniques utilized in LIS education during and after the COVID-19 epidemic. It investigates the impact of digital media, feedback, formative assessments, and concerns such as cheating and authenticity, providing critical insights for future assessment practises in the post-pandemic period. Accordingly, there is a pressing need to employ new assessment tools post-pandemic to adapt to online and hybrid learning challenges. This qualitative study investigates complex social phenomena in higher education assessments by exploring behaviours, preferences, beliefs, customs, attitudes, viewpoints, and experiences. Twelve LIS instructors, 6 teaching and learning administrators, and 20 LIS students from South Africa and Nigeria were chosen using convenience sampling. Key informant interviews were conducted, with constructivist learning orientation-driven questions examining new assessment technologies, the role of digital media in student assessment, authenticity concerns in e-assessment, feedback and formative assessments. The research concludes that incorporating Computer-Based Learning (CLT) in e-assessments for LIS education enhances students’ knowledge construction and accessibility. Digital examinations offer benefits like instant feedback and personalized learning experiences, leading to improved problem-solving skills and decision-making. Future research should focus on larger, diverse samples and longitudinal approaches to evaluate intervention effectiveness and sustainability

Media Distraction in College Students.

Recent development of media technology has greatly changed how students learn. Studying has become increasingly dependent on computer and the Internet, where students have easy access to a world of distractions. This dissertation consists of three studies that observed the amount of media usage during college students’ study activities (Study 1) and investigated the effect of media distraction on their memory (Study 2), reading and quantitative reasoning (Study 3). Results showed that college students from both China and the USA spent a sizable amount of their study time on media activities; lab experiments showed that media activities negatively affected students’ logical memory and reading comprehension, but did not affect performance on a quantitative reasoning task. In addition, the effect of media distraction on reading was negatively related to students’ daily social media usage, suggesting that heavy social media users might have developed adaptations to media distractions. Current college students have grown up with social media websites, and many of them are constantly connected to smart devices. By studying the impact of these technological experiences on their learning and cognition, the dissertation identifies problems of student learning in this digital era, which in turn has implications for educational practices. It also contributes to understanding of the interaction between technological development and changes in human cognition.PhDEducation and PsychologyUniversity of Michigan, Horace H.
