Mind wandering during hypertext reading: The impact of hyperlink structure on reading comprehension and attention.

Online reading is becoming more and more popular in learning and teaching environments. However, little is known about characteristics of hypertexts that influence on reading comprehension and attention. Some previous studies have suggested that attention failures also referred to as mind wandering (MW) occur whenever the available resources of the reader (e.g., working memory capacity; WMC) do not match the task demands (e.g., text difficulty). This study aims to investigate the effect of restructuring a linear text into different hypertext types by means of hyperlinks on MW in a cognitively demanding task like reading. We hypothesized that participants exposed to a difficult to read hypertext with networked structure engage more in task-unrelated thoughts (TUTs) compared to participants asked to read a difficult but hierarchically organized hypertext. 90 participants read either an easy or difficult version of the same unfamiliar hypertext with either a hierarchical or networked structure and with embedded thought probes. Reading comprehension and WMC measures followed. As expected, participants reading the difficult (to read) hypertext with networked link structure showed significantly more TUTs than participants reading the hierarchical link structure hypertext. In addition, readers with a low-WMC showed significantly more TUTs while reading a demanding hypertext regardless of its structure. These findings are in line with the view that mind wandering occurs if available resources do not match with task demands, and thus deepen assumptions about hyperlinks as new cohesive devices.

Periodismo científico y perfil periodístico como elementos metodológicos para la construcción de historias Hipermediales / Scientific journalism and journalistic profile as methodological elements for the construction of hypermedia stories

Resumen Este artículo aborda las experiencias, metodología y aprendizajes resultantes del proyecto de investigación-creación Periodismo interactivo. Historias de investigadores en el Eje Cafetero, financiado por la Universidad de Manizales y en alianza con la Fundación Academia de Dibujo Profesional de Cali. Esta iniciativa se centró en tres elementos: una base del periodismo científico y dos columnas: el perfil como género periodístico y la hipermedialidad como canal. Luego de escoger dos historias de científicos con relevantes logros e impactos, se aplicaron los elementos del perfil como género periodístico para construir historias basadas en las experiencias, fuentes, datos y percepciones del equipo de trabajo. Igualmente se cuentan los hitos científicos con las herramientas del periodismo científico para valorar dichos impactos y transcodificarlos para audiencias no especializadas y, finalmente, se eligieron momentos, intervenciones e información relevante para construir una propuesta hipermedial que acompañará el libro que recoge ambas historias.

Abstract This article addresses the experience, methodology and learning resulting from the research-creation project Scientific Profiles and Hypermediality financed by the University of Manizales and in alliance with the Cali Professional Drawing Academy Foundation. This initiative focused on three elements: a base of scientific journalism and two columns: the profile as a journalistic genre and hypermediality as a channel. After choosing two stories of scientists with relevant achievements and impacts, the elements of the profile were applied as a journalistic genre to build stories based on the experiences, sources, data and perceptions of the work team. Likewise, scientific milestones were contracted with the tools of scientific journalism to assess those impacts and transcode them for non-specialized audiences and, finally, moments, interventions and relevant information were chosen to build an hypermedial proposal that would accompany the book that collects both stories.

Evolution of nursing teaching in the use of education technology: a scoping review.

OBJECTIVE: To identify and map the technological tools of information and communication to support the teaching learning process in Nursing teaching courses. METHODS: This is a scoping review whose search was carried out in seven databases and in grey literature. After an initial analysis of the selection, 88 texts were read integrally, and 29 made up the final sample. RESULTS: Virtual learning environment and object, simulation, hypermedia, and software or cellphone applications were the tools the nursing professors used the most. Studies highlight that the application of technology was important in the teaching-learning process, since it encouraged teaching based on safe care, motivating and developing abilities/competences, supported on significant, effective, flexible, and autonomous learning. CONCLUSION: The contribution of the technology for nursing formation stands out, but it should be highlighted that its employment must be critical, reflective, based on pedagogical theories and developed by trained professors.

Virtual Reality Aids Game Navigation: Evidence from the Hypertext Lostness Measure.

Instead of traditional free movement, node-based movement can be used in virtual reality (VR) games. In node-based movement systems, players navigate by jumping to set locations. Node-based movement is similar to hypertext navigation. We show that the hypertext lostness measure can be used as a game analytic to evaluate navigational efficiency. In a randomized controlled trial with 25 adolescent participants, an immersive desktop game environment and a VR game environment were compared on the transmission of in-game educational content and navigational efficiency. Results show that the hypertext lostness measure is also valuable outside its original hypertext domain: in VR. VR did not improve players' retention of factual knowledge, but did significantly improve players' spatial knowledge and navigational efficiency. We conclude (a) the hypertext lostness measure is also valuable for node-based VR games and (b) VR games add to spatial learning, even when compared with already immersive desktop games.

Fact-checking e saúde: análise da seção 'Verdade ou Boato' de GaúchaZH / Fact-checking and health: an analysis of GaúchaZH's 'Verdade ou Boato' (Truth or Rumor) section / Fact-checking y salud: un análisis de la sección 'Verdade ou Boato' (Verdad o rumor) de GaúchaZH

Este artigo analisa a seção 'Verdade ou Boato', publicada no jornal Zero Hora (meio impresso) e no GaúchaZH (meio digital), com o objetivo de compreender as características das matérias produzidas na seção e o perfil das informações nela checadas; e tensionar como os veículos agenciam sua posição de credibilidade em relação às alterações nos modos de produção e circulação de conteúdos no ambiente digital, especialmente na área temática da saúde. Os procedimentos metodológicos utilizados são as pesquisas bibliográfica e documental e a análise de conteúdo de um corpus composto por 25 matérias. Como resultado, observa-se que a iniciativa de checagem de informações reforça o jornalismo como sistema perito. Entre as características identificadas, destaca-se a adaptação das manchetes para negar informações falsas. Na edição digital, observa-se o pouco uso do potencial que tem o hipertexto para compor uma narrativa sustentada por evidências.

Blogs e redes sociais na atenção à saúde da família: o que a comunicação online traz de novo? / Blogs and social networks in the family health care: what kind of contribution to innovation the online information bring about? / Blogs y redes sociales en la atención a la salud de la familia: ¿qué innovaciones la comunicación online trae?

O uso de tecnologias da informação e da comunicação (TIC) tem apoiado mudanças nas formas de comunicação das instituições de saúde. O estudo que fundamenta este artigo investiga a criação de ambientes de comunicação online nos serviços de atenção primária no município do Rio de Janeiro, selecionando o caso do Observatório de Tecnologia de Informação e Comunicação em Sistemas e Serviços de Saúde (Otics - Rio), posteriormente substituído pelos Ambientes de Saberes e Aprendizagens em Saúde (Asas - Rio). A análise considera seis características da comunicação online: interatividade, hipertextualidade, personalização, multimidialidade/convergência, memória e instantaneidade. Observou-se que a comunicação estabelecida mantém uma tendência difusionista, característica do modelo informacional de comunicação, especialmente nos blogs, evidenciando que é mesmo possível tender à reprodução de antigos modelos e sentidos de comunicação e saúde.

The use of information and communication technologies (ICT) has collaborated with changes in the ways of communication used in health institutions. This article bases on a study that examines the development of online information services on the primary health care in Rio de Janeiro, Brazil, analysing the Otics-Rio - Observatório de Tecnologia de Informação e Comunicação em Sistemas e Serviços de Saúde (Observatory of Information and Communication Technology in Health Systems and Services), later replaced by the Asas-Rio - Ambientes de Saberes e Aprendizagens em Saúde (Environments of Health Knowledge and Learning). The analyse of these environments based on six basic characteristics of online communication: interactivity, hypertextuality, personalization, multimediality/convergence, memory and instantaneity. It was observed that the communication established has a diffusionist tendency especially in the blogs, evidencing that the use of the TIC can produce improvements but also tend to the reproduction of old models and senses of communication and health.

Title, abstract, and keyword searching resulted in poor recovery of articles in systematic reviews of epidemiologic practice.

OBJECTIVE: Article full texts are often inaccessible via the standard search engines of biomedical literature, such as PubMed and Embase, which are commonly used for systematic reviews. Excluding the full-text bodies from a literature search may result in a small or selective subset of articles being included in the review because of the limited information that is available in only title, abstract, and keywords. This article describes a comparison of search strategies based on a systematic literature review of all articles published in 5 top-ranked epidemiology journals between 2000 and 2017. STUDY DESIGN AND SETTING: Based on a text-mining approach, we studied how nine different methodological topics were mentioned across text fields (title, abstract, keywords, and text body). The following methodological topics were studied: propensity score methods, inverse probability weighting, marginal structural modeling, multiple imputation, Kaplan-Meier estimation, number needed to treat, measurement error, randomized controlled trial, and latent class analysis. RESULTS: In total, 31,641 Hypertext Markup Language (HTML) files were downloaded from the journals' websites. For all methodological topics and journals, at most 50% of articles with a mention of a topic in the text body also mentioned the topic in the title, abstract, or keywords. For several topics, a gradual decrease over calendar time was observed of reporting in the title, abstract, or keywords. CONCLUSION: Literature searches based on title, abstract, and keywords alone may not be sufficiently sensitive for studies of epidemiological research practice. This study also illustrates the potential value of full-text literature searches, provided there is accessibility of full-text bodies for literature searches.

On the limit value of compactness of some graph classes.

In this paper, we study the limit of compactness which is a graph index originally introduced for measuring structural characteristics of hypermedia. Applying compactness to large scale small-world graphs (Mehler, 2008) observed its limit behaviour to be equal 1. The striking question concerning this finding was whether this limit behaviour resulted from the specifics of small-world graphs or was simply an artefact. In this paper, we determine the necessary and sufficient conditions for any sequence of connected graphs resulting in a limit value of CB = 1 which can be generalized with some consideration for the case of disconnected graph classes (Theorem 3). This result can be applied to many well-known classes of connected graphs. Here, we illustrate it by considering four examples. In fact, our proof-theoretical approach allows for quickly obtaining the limit value of compactness for many graph classes sparing computational costs.

Improvement of Self-regulated Learning in Mathematics through a Hypermedia Application: Differences based on Academic Performance and Previous Knowledge.

Self-regulation on behalf of the student is crucial in learning Mathematics through hypermedia applications and is an even greater challenge in these IT environments. Two aims are formulated. First, to analyze the effectiveness of a hypermedia tool in improving perceived knowledge of self-regulatory strategies and the perceived usage of the planning, executing and assessment strategy on behalf of students with low, medium and high levels of academic performance. Second, to analyze the effectiveness of the hypermedia tool in improving perceived usage of the strategy for planning, monitoring and evaluating on behalf of students with a perceived knowledge (low, medium and high). Participants were 624 students (aged 10-13), classified into a treatment group (TG; 391) and a comparative group (CG; 233). They completed a questionnaire on perceived knowledge (Perceived Knowledge of Self-Regulatory Strategies) and another one on perceived usage of the strategy for planning, performing and evaluating (Inventory of Self-regulatory Learning Processes). Univariate covariance analyses (ANCOVAs) and Student-t tests were used. ANCOVA results were not statistically significant. However, the linear contrast indicated a significant improvement in perceived knowledge of strategies among the TG with low, medium and high academic performance (p ≤ .001). Results are discussed in the light of past and future research.
