Latent profiles of children's shyness: Behavioral,affective, and physiological components

Shyness can manifest on behavioral, affective, and physiological levels, but little is known about how these components cluster. We coded behavioral expressions of avoidance/inhibition, collected self-reported nervousness, and measured cardiac vagal withdrawal in 152 children (M_age = 7.82 years, 73 girls, 82% White) to a speech task in 2018–2021. A latent profile analysis using these behavioral, affective, and physiological indicators revealed four profiles: average reactive (43%), lower affective reactive (20%), higher affective reactive (26%), and consistently higher reactive (11%). Membership in the higher reactive profile predicted higher parent-reported temperamental shyness across 2 years. Findings provide empirical support for the long-theorized idea that shyness might exist as an emotional state but also represents a distinct temperamental quality for some children.     

Interpretative Responses to English Educational Television

The paper is concerned with the need to stimulate and evaluate pupils’ responses to educational television broadcasts in English. In particular, it presents a comparative assessment of written follow‐up work during a series of broadcasts. Case study methods are used within one comprehensive school and involve 49 15‐year‐old pupils. Results suggest that those pupils consistently engaging in small‐group discussion are likely to produce better written work and to develop greater independence in formulating their ideas.

Using social network analysis to measure the impact and value of work that takes us beyond institutional boundaries

In educational development, accountability is paramount, in particular for activities that take educational developers away from their institutional boundaries to local, national, and international venues. Educational developers must demonstrate the benefits of such work to the home institution and its constituents. We asked educational developers from around the world to comment on the nature and value of their external work. Their responses made clear that such work expands valuable social networks and, concomitantly, builds social capital. Using these observations, we explain how social network analysis can be used to assess and demonstrate the impact of external work.     

Do we have any theories of group communication?

The essay presents criteria for a “good theory” and then reviews advances in small group communication research during the 1980s. The fact that comparatively few scholars are dedicated to such research is then related to the criteria for good theory in discussions of, first, metaphors and imagination; second, puzzles and problems; and third, real‐world significance and outcomes. A call is made for the kind of research that will result in better small group theory.     

Promoting Online Collaborative Learning Experiences for Teenagers

This paper describes a project that engages teenagers in using Internet-based tools to collaborate in problem-based learning. Motorola Expeditions is designed to help young people develop skills in using new network technologies to work together in teams to solve real world problems. In Expeditions 2000, 27 teenagers worked in teams with six on-site and four online mentors to develop a marketing plan for one or more personal communication sector technologies, such as cell phones, specifically targeting teenage consumers. Participants were surveyed before and after the project about their attitudes towards collaborative learning, their confidence in collaborating online and their competence in using certain online tools. Data were also gathered through observation of online communication, weekly feedback surveys and interviews with mentors. Results show a significant increase in the participants' self-confidence in collaborating online and in their competence in using online communication tools to collaboratively solve problems. La promotion d’expériences éducatives en ligne en en collaboration pour des adolescents. Cet article décrit un projet que engage des adolescents à utiliser des outils basés sur internet pour collaborer dans l'enseignement fondé sur la résolution de problèmes. Les expéditions Motorola sont concues pour aider les jeunes à développer des compétences pour utiliser les nouvelles technologies du réseau et travailler en équipes pour résoudre les problèmes réels du monde. Dans les Expéditions 2000, 27 adolescents ont travaillé en équipes avec 6 tuteurs sur le site et quatre en ligne pour élaborer un plan de marketing pour une en plusieurs technologies de communication personnelles telles que les téléphones portables visant spécialement des consommateurs adolescents. On a sondé les participants avant et après le projet sur leurs attitudes à l'égard de l'enseignement en collaboration de leur confiance dans la collaboration en ligne et de leur compétence dans l'utilisation de certains outils en ligne. On a aussi recueilli des données grâce à l'observation de la communication en ligne, grâce à des contrats de feedback hebdomadaires et de entretiens avec les tuteurs. Les résultats montrent une augmentation significative de la confiance in soi des participants à la collaboration en ligne et de leur compétence dans l'utilisation des outils de communication en ligne pour résoudre les problèmes en collaboration. Förderung von online collaborativen Lernerfahrungen für Jugendliche. Die Abhandlung beschreibt ein Projekt, in dem Jugendliche mit Hilfe von Internet Werkzeugen Lernprobleme gemeinsam lösen. Motorola Expeditions wurde konzipiert, um jungen Menschen zu helfen, Fertigkeiten in der Anwendung neuer Netzwerktechnologien zu entwickeln und als Team zusammen zu arbeiten um reale Probleme zu lösen. In Expeditons 2000 arbeiteten 27 Jugendliche in Teams mit 6 “onsite"- und 4 online-Lehrkräften, um einen Marketingplan für einen oder mehr Sektoren betreffende individuelle Kommunikationstechnologien zu entwickeln, wie z.B. mobile Telefone, die sich insbesondere an jugendliche Verbraucher wenden. Die Teilnehmer wurden vorher und nach dem Projekt zu ihrer Einstellung zum collaborativen Lernen befragt, ihrem Zutrauen in das gemeinsame online-Arbeiten und zu ihrer Kompetenz hinsichtlich der Anwendung gewisser online Werkzeuge. Die Daten wurden auch durch Observation von online-Kommunikation, wöchentlichen Auswertungen und Interviews mit den Lehrkräften gesammelt. Die Resultate zeigen eine deutliche Steigerung des Selbstvertrauens der Teilnehmer online zusammenzuarbeiten, sowie ihrer Fähigkeit, online- Kommunikationswerkzeuge zu nutzen, um gemeinsam Probleme zu lösen.     

A comparison of traditional and modified Summated-Heart-Rate-Zones models to measure internal training load in basketball players

The Summated-Heart-Rate-Zones training load (SHRZ TL) model is used to measure internal loading; however, a major limitation of this approach is the use of broad heart rate (HR) zones to quantify exercise intensity. Therefore, this study aimed to compare SHRZ TL outcomes derived using the traditional model and modified approaches using smaller HR zones. HR responses were monitored in 15 semi-professional basketball players during preparatory training to calculate SHRZ TL using the traditional approach with 10%HR_max zones (SHRZ₁₀) and modified approaches with 5%HR_max zones (SHRZ₅) and 2.5%HR_max zones (SHRZ_2.5). Significant (P < 0.001) differences were evident in SHRZ TL between SHRZ₁₀ (254.2 ± 41.7 AU) and SHRZ₅ (275.9 ± 43.3 AU, unclear, small) as well as SHRZ_2.5 (286.7 ± 44.3 AU, very likely, moderate). Use of SHRZ_2.5 provides novel insight regarding internal loading in basketball players and may carry greater sensitivity for detection of maladaptive and adaptive responses to training.
