The Impact of Video Length on Learning in a Middle-Level Flipped Science Setting: Implications for Diversity Inclusion

Popularity of videos for classroom instruction has increased over the years due to affordability and user-friendliness of today’s digital video cameras. This prevalence has led to an increase in flipped, K-12 classrooms countrywide. However, quantitative data establishing the appropriate video length to foster authentic learning is limited, particularly in middle-level classrooms. We focus on this aspect of video technology in two flipped science classrooms at the middle school level to determine the optimal video length to enable learning, increase retention and support student motivation. Our results indicate that while assessments directly following short videos were slightly higher, these findings were not significantly different from scores following longer videos. While short-term retention of material did not seem to be influenced by video length, longer-term retention for males and students with learning disabilities was higher following short videos compared to long as assessed on summative assessments. Students self-report that they were more engaged, had enhanced focus, and had a perceived higher retention of content following shorter videos. This study has important implications for student learning, application of content, and the development of critical thinking skills. This is particularly paramount in an era where content knowledge is just a search engine away.     

Early childhood education and care in a context of social heterogeneity and inequality. Empirical notes on an interdisciplinary challenge

Against a background of increasing inequality and its impact at various levels on childhood and family life, of the growing societal significance and uptake of extra-familial childcare provision, and of social policy goals emphasising participation and education for all, the early childhood education and care (ECEC) sector in Germany is facing new and heightened challenges. This article presents and analyses current and empirically observable changes in society. It comes to the conclusion that ECEC needs to be more strongly viewed as an interdisciplinary challenge, and that ways forward need to include a comprehensive professionalisation and workforce development project: the aim must be to provide children and families with care and support services tailored both quantitatively and qualitatively to their needs, thereby offering not only support to facilitate the reconciliation of work and family obligations and an alternative place of education for children, but also programmes of specific support for disadvantaged and support-dependent children and families.     

On Location Learning: Authentic Applied Science with Networked Augmented Realities

The learning of science can be made more like the practice of science through authentic simulated experiences. We have created a networked handheld Augmented Reality environment that combines the authentic role-playing of Augmented Realities and the underlying models of Participatory Simulations. This game, known as Outbreak @ The Institute, is played across a university campus where players take on the roles of doctors, medical technicians, and public health experts to contain a disease outbreak. Players can interact with virtual characters and employ virtual diagnostic tests and medicines. They are challenged to identify the source and prevent the spread of an infectious disease that can spread among real and/or virtual characters according to an underlying model. In this paper, we report on data from three high school classes who played the game. We investigate students’ perception of the authenticity of the game in terms of their personal embodiment in the game, their experience playing different roles, and their understanding of the dynamic model underlying the game.     

Professor or Knowledge Worker? The Politics of Defining Faculty Work

To define “contractual regulations and institutional practices” for university faculty we need to consider significant changes in academic work in the last two decades. On the one hand, there persists the traditional view of disciplinary knowledge as valuable for its own sake; on the other, universities are a driving force in providing intellectual capital for the new knowledge society. While academic contracts have traditionally focused on defining work regulations and guidelines, faculty freedoms, tenure and so on, within the disciplinary framework, today these issues are deeply dependent on how the university's post‐Fordist organizational model (centralized controls, disaggregated models for managing knowledge) delivers knowledge in which symbolic and exchange values can play conflicting roles.     

The direct and indirect effects of word reading and vocabulary on adolescents’ reading comprehension: Comparing struggling and adequate comprehenders

The current study examined statistically significant differences between struggling and adequate readers using a multicomponent model of reading comprehension in 796 sixth through eighth graders, with a primary focus on word reading and vocabulary. Path analyses and Wald tests were used to investigate the direct and indirect relations of word identification, vocabulary, silent reading efficiency, and inference-making on reading comprehension. Comparing struggling versus adequate comprehenders revealed statistically significant differences in path coefficients. In both groups, vocabulary had the largest total effect when considering its direct and indirect effects. Word identification was the strongest direct predictor for struggling comprehenders (β = .18 for struggling vs. β = ? .03 for adequate), while vocabulary was the strongest predictor for adequate comprehenders (β = .40 for adequate vs. β = .14 for struggling). Findings reinforce (a) vocabulary knowledge plays a primary role in explaining individual differences in adolescent reading comprehension, (b) the need to differentiate intervention to address underlying difficulties of struggling readers, and (c) the relations of reading component skills (e.g., word reading and silent reading efficiency) to reading comprehension may be different based on reader proficiency.     

Multiple language use and mathematics: Politicizing the discussion

Macroeconomic forces, globalization, transnational capital flight, and massive migration have global and local reverberations that affect our classrooms, teachers, communities, and students. In particular, teaching and learning mathematics in multiple language contexts is affected by these broader dynamics. Thus, politicizing the discussion around language usage is not a choice mathematics educators have the luxury of making-circumstances dictate that for us. This brief commentary responds to the six articles in the present volume and situates them within the larger sociopolitical context we live in today.     

Recapitulating the History of Sickle-Cell Anemia Research

This paper provides an argument in favor of a specific pedagogical method of using the history of science to help students develop more informed views about nature of science (NOS) issues. The paper describes a series of lesson plans devoted to encouraging students to engage, unbeknownst to them, in similar reasoning that led scientists to understand sickle-cell anemia from the perspective of multiple subdisciplines in biology. Students pursue their understanding of a ‘mystery disease’ by means of a series of open-ended problems that invite them to discuss it from the perspective of anatomy, physiology, ecology, evolution, and molecular and cell biology. Throughout this unit, instructors incorporate techniques that invite students to explicitly and reflectively discuss various NOS issues with reference to this example and more generally. It is argued on the grounds of constructivist tenets that this pedagogy has substantial advantages over more implicit approaches. The findings of an empirical study using an open-ended survey and follow-up, semi-structured interviews to assess students’ pre- and post-instruction NOS conceptions support the efficacy of this approach.     

Children with Disabilities and the Education System: the experiences of fifteen fathers

Fifteen fathers of children with disabilities living in urban and rural settings were interviewed about their experiences which included their interactions with teachers and other professionals in the school system. The fathers’ accounts revealed issues similar to those reported in studies in which mothers were the participants. Where early childhood centres and schools are rejecting of children with disabilities, and where resources are difficult to access, parents experience stress. Supportive professionals and educational settings, on the other hand, are experienced as contributing to child development and family well‐being.
