Reducing the prior-knowledge achievement gap by using technology-assisted guided learning in an undergraduate chemistry course

There have been many practical obstacles for teachers to implement evidence-based educational technology, especially in STEM classrooms. By implementing learning principles related to Cognitive Load Theory, we developed an innovative Technology-Assisted Guided Learning (TAGL) approach and its web-based instructional tool, combining expertise from educational research and best teaching practices to enhance guided student-centered learning in chemistry. A total of 185 community college students were randomly assigned to learn stoichiometry through either TAGL or one of two active control interventions, traditional direct instruction and Khan Academy, a widely used web learning platform. We found that the TAGL group significantly outperformed both active control groups immediately after instruction, and furthermore, despite the fact that all groups received additional instruction in stoichiometry, the beneficial effects of TAGL compared to the control groups were maintained a month later. Notably, TAGL was able to eliminate the achievement gap between students with low prior knowledge and students with high prior knowledge. Furthermore, prior-knowledge activation was found to be especially beneficial for students with low prior knowledge. Our work contributes to existing research in learning theories and provides new insight toward the development of more effective and adaptive instructional designs. By translating research into practice, this study demonstrates the great potential of using innovative computer-based technology to improve student learning for all.     

Connecting inside out: Development of the social brain in infants and toddlers with a focus on myelination as a marker of brain maturation

Early childhood is a sensitive period for learning and social skill development. The maturation of cerebral regions underlying social processing lays the foundation for later social-emotional competence. This study explored myelin changes in social brain regions and their association with changes in parent-rated social-emotional development in a cohort of 129 children (64 females, 0–36 months, 77 White). Results reveal a steep increase in myelination throughout the social brain in the first 3 years of life that is significantly associated with social-emotional development scores. These findings add knowledge to the emerging picture of social brain development by describing neural underpinnings of human social behavior. They can contribute to identifying age-/stage-appropriate early life factors in this developmental domain.     

Preschool children’s Collaborative Science Learning Scaffolded by Tablets

This paper reports on a project aiming to extend the current understanding of how emerging technologies, i.e. tablets, can be used in preschools to support collaborative learning of real-life science phenomena. The potential of tablets to support collaborative inquiry-based science learning and reflective thinking in preschool is investigated through the analysis of teacher-led activities on science, including children making timelapse photography and Slowmation movies. A qualitative analysis of verbal communication during different learning contexts gives rise to a number of categories that distinguish and identify different themes of the discussion. In this study, groups of children work with phase changes of water. We report enhanced and focused reasoning about this science phenomenon in situations where timelapse movies are used to stimulate recall. Furthermore, we show that children communicate in a more advanced manner about the phenomenon, and they focus more readily on problem solving when active in experimentation or Slowmation producing contexts.     

eSport: Vom Präfix zum Thema für den organisierten Sport!?

In an increasingly differentiated culture of movement, play and sport as well as a more and more digitized society, the topic of eSports has been intensively discussed in recent time. The objective-categorical basics of the discussion seem to be clear only at first sight. A closer look points to the need of a differentiated cross-disciplinary discussion of the topic. It becomes clear that above all the underlying understanding of sport, the content-related demarcation as well as the social positioning contribute decisively to the perception of eSport (approval/rejection). The present article takes up the discussion with reference to the heterogeneity, heteronomy and complexity of sports and provides an alternative interpretive idea on the topic.

Coach–athlete sexual relationships: if no means no does yes mean yes?

Coach–athlete romantic relationships and consensual sexual relations are commonly accepted among coaches and athletes, although a growing number of sport organisations discourage or prohibit such relationships. In research, coach–athlete sexual relationships are lumped together with sexual abuse, suggested to harm athletes' well-being, performance, athletic career and team dynamics, and to inherently constitute an abuse of power, trust and ethics. In addition, mistrust of coaches' motives, related to physical touch and fear of sexual misconduct, has resulted in a growing anxiety among coaches. This paper highlights and critically discusses research conceptualisations, contextual understandings and critical issues surrounding coach–athlete sexual relationships, on which there is no comprehensive research outside the sexual abuse context. Studies of authority–subordinate romantic relationships in other social settings have reported that such relationships facilitate both positive and negative characteristics and outcomes. To prevent and reduce harm and to promote well-being, functionality and safe practice in coach–athlete sexual and non-sexual relationships, I suggest that comprehensive research outside the sexual abuse context is required. In addition to the previous research focus on harmful and abusive relationships, coach–athlete sexual relationships that are experienced as consenting and mutually fulfilling by the involved parties need further examination.     

Exploring a pluralist understanding of learning for sustainability and its implications for outdoor education practice

This article explores a pluralist understanding of learning for sustainability in educational theory and relates it to outdoor education practice. In brief, this kind of learning can be described as a deep engagement with an individual’s multiple identities and the personal location in diverse geo-physical and socio-cultural surroundings. I identify the intersection of learning for sustainability and pluralism in three themes: learning as transformation, learning as participation and learning about identities and spaces. The reflections on what kind of learning outdoor education could seek to promote potentially help the field to clarify its role as a sustainable education approach. A programme designed to be responsive to both sustainability and pluralism would enable learners to explore the multifacetedness of a location and provide space for them to share and exchange individual experiences, perceptions and worldviews.
