Factors influencing teachers’ adoption of AR inquiry games to foster skills for Responsible Research and Innovation

Responsible Research and Innovation (RRI) is a contemporary approach to promote science with and for society for aligning scientific innovations with societal needs. Literature about education for RRI is limited because it is not a widespread practice at the moment. To explore this gap, this study examines teachers’ views about a novel inquiry game with Augmented Reality to foster inquiry skills for RRI. This game about Genetic-Modified food was used by 18 educators from Secondary and Higher Education who engaged 390 students to form opinions about risks and benefits of GM cereal. The thematic analysis of qualitative data: semi-structured questionnaires, teaching reports and focus groups, revealed motivations and practices that influence teachers’ adoption of OER created with new technologies. Findings revealed that the 3-phase-model approach used in the game engaged students to “CARE” about global issues, “KNOW” science concepts and “DO” actions through an active open schooling network. The key drivers for educators’ adoption of AR inquiry games are to make learning more meaningful and engaging through students-centred approaches and topical resources for them to develop scientific knowledge and skills. However, the key requirements for that are easy-to-use technologies and pedagogical strategies for identifying learner’s achievements and difficulties.     

Classroom environments: an experiential analysis of the pupil–teacher visual interaction in Uruguay

We argue that the traditional physical environment is commonly taken for granted and that little consideration has been given to how this affects pupil–teacher interactions. This article presents evidence that certain physical environments do not allow equal visual interaction and, as a result, we derive a set of basic guiding principles that could contribute to the improvement of classroom design. Discussions about research on the design of classroom spaces and the methods to evaluate them articulate the rationale for this study. We seek to accomplish this by focusing on two fundamental variables of the face-to-face communication process: visual and distance. They are discussed in the context of four classroom case studies. The method is based on a hybrid approach composed of first-hand video-photographic records, isovist analysis and proxemic information regarding distances. The conclusions suggest that the proportion and spatial configuration of a classroom have a substantial impact on the number of pupils receiving high-quality visual interaction with the teacher. Finally, the importance of integrating experiential analysis in the architectural design process to ensure the quality and equality of the interaction among the protagonists of the teaching and learning process is highlighted.     

The World Bank Policies: Damned if you do,damned if you don't

To some, the World Bank is the all-powerful arm of imperialism. Others regret that it is powerless, incapable of influencing policies in the countries in which it operates. This paper discusses these issues, as seen by the author, a former employee both of the World Bank and the Inter-American Development Bank, as well as a civil servant and consultant at the receiving end of the loans. This experience provides an inside view but the reader has to be warned of the biases that might have resulted from it.     

Role of affective self-regulatory efficacy in diverse spheres of psychosocial functioning

This prospective study with 464 older adolescents (14 to 19 years at Time 1; 16 to 21 years at Time 2) tested the structural paths of influence through which perceived self-efficacy for affect regulation operates in concert with perceived behavioral efficacy in governing diverse spheres of psychosocial functioning. Self-efficacy to regulate positive and negative affect is accompanied by high efficacy to manage one's academic development, to resist social pressures for antisocial activities, and to engage oneself with empathy in others' emotional experiences. Perceived self-efficacy for affect regulation essentially operated mediationally through the latter behavioral forms of self-efficacy rather than directly on prosocial behavior, delinquent conduct, and depression. Perceived empathic self-efficacy functioned as a generalized contributor to psychosocial functioning. It was accompanied by prosocial behavior and low involvement in delinquency but increased vulnerability to depression in adolescent females.     

History, Philosophy, and Science in a Social Perspective: A Pedagogical Project

Various studies have promoted instruction in the history and philosophy of science (HPS) in science classes, but the best way of putting this perspective into practice remains undetermined. To contribute to this issue, we developed a pedagogical project in some high schools in Brazil that aimed to present science content using an historical–philosophical approach focusing on the HPS from a social perspective. The content was developed broadly, highlighting the dialogues between science and the cultures in which scientific knowledge was accumulated. The results of the first stage of project implementation show that some strategies efficiently encouraged student discussion about science using an historical–philosophical approach. One successful strategy was the use of artistic material, such as movies and plays. The creative language and images in these elements allowed teachers to broaden historical–philosophical discussions without compromising science content. This project shows that a social approach to the HPS stimulates interdisciplinary discussions in science classes, enabling students to reflect on the nature of science.     

Verification of the stomatal conductance of Nebbiolo grapevine

Wine is one of the most important Italian export products, and Nebbiolo is one of the most respected Italian grapes. In the summer of 2007, a measurement campaign was carried out in a Nebbiolo vineyard located in Vezza d＇Alba, near Cuneo, Italy. Using a gauge of trade gases and some other instruments, we recorded the stomatal conductance and also some physiological parameters useful for estimating the dependence of stomatal conductance on environmental variables. The goal of this experiment was improving the parameterization of grapevine evapotranspiration through the assessment of the stomatal conductance and, in particular, of the functional dependence of the stomatal conductance on the following variables： the photosynthetically active radiation, the atmospheric temperature, the atmospheric moisture deficit, and the carbon dioxide concentration. The observations allowed us to check and, in some cases, to adapt the existing general parameterizations found in literature. The results showed some significant differences with the existing parameterizations concerning the atmospheric temperature, the atmospheric moisture deficit, and the carbon dioxide concentration. The parameterizations obtained in this experiment, although referring to a specific plant and site （namely the Nebbiolo at Vezza d＇Alba）, could allow assessment of the best environmental conditions under which the Nebbiolo grapevine production is the best, and in future could be tested for other grapevines or climates.     

Motor unit activation strategy during a sustained isometric contraction of finger flexor muscles in elite climbers

The aim of the study was to evaluate, by an electromyographic (EMG) and mechanomyographic (MMG) combined approach, whether years of specific climbing activity induced neuromuscular changes towards performances related to a functional prevalence of fast resistant or fast fatigable motor units. For this purpose, after the maximum voluntary contraction (MVC) assessment, 11 elite climbers and 10 controls performed an exhaustive handgrip isometric effort at 80% MVC. Force, EMG and MMG signals were recorded from the finger flexor muscles during contraction. Time and frequency domain analysis of EMG and MMG signals was performed. In climbers: (i) MVC was higher (762 ± 34 vs 512 ± 57 N; effect size: 1.64; confidence interval: 0.65–2.63; P < 0.05); (ii) endurance time at 80% MVC was 43% longer (34.2 ± 3.7 vs 22.3 ± 1.5 s; effect size: 1.21; confidence interval: 0.28–2.14; P < 0.05); (iii) force accuracy and stability were greater during contraction (P < 0.05); (iv) EMG and MMG parameters were higher throughout the entire isometric effort (P < 0.05). Collectively, force, EMG and MMG combined analysis revealed that several years of specific climbing activity addressed the motor control system to adopt muscle activation strategies based on the functional prevalence of fast resistant motor units.
