Physics teaching and learning with multimedia applications: a review of teacher-oriented literature in 34 local language journals from 2006 to 2015

Teacher-oriented journals provide many ideas for practical use of multimedia in physics teaching and learning. However, they are often written in their respective native languages. Moreover, having 24 official languages in the European Union is a huge barrier to the exchange of teaching and learning material. Knowledge about what is discussed in neighbouring countries is rare. Hence, in this article scientific members of the MPTL group (Multimedia in Physics Teaching and Learning) present a review on multimedia applications and the corresponding concepts that are discussed in non-English language journals. 491 articles in 34 teacher-oriented journals from 10 countries are reviewed, using a list of 81 categories, to characterise addressed topics, teaching strategies, technology and multimedia features. Log-linear multiway frequency and cluster analysis were used to get more insights about preferred combinations of content and teaching strategies, differences between countries, changes between periods and patterns of articles. There is a divergence in the main topics focused on between countries and some changes within the periods 2006–2010 and 2011–2015. Such a large diversity of ideas and concepts covered throughout the EU highlights the potential benefits of more international exchange. However, findings also point to additional requirements, concerning theoretical background, ideas for implementations of modern features like augmented reality, and the use of internet-based sources and modern devices. Thus this article is also calling for more exchange and discussions concerning topics to be addressed in teacher-oriented journals.     

Seeing education with one's own eyes and through PISA lenses: considerations of the reception of PISA in European countries

The paper addresses the Organization for Economic Cooperation and Development's Program for International Student Assessment (PISA) as a public policy instrument, whose worldwide circulation is mediated by processes of reinterpretation, negotiation, and re-contextualization, where national, local, and international agencies intertwine. It is focused on the active reception of PISA in six European spaces (Francophone Belgium, France, Hungary, Portugal, Romania, and Scotland) along its first three cycles. The paper identifies two contrasting developments: the Program's divergent uses and its attractiveness in different social worlds. The paper gives particular attention to what is called the ‘update of reference societies’ in the context of national receptions of PISA. These ‘updates’ are analyzed as part of a composite process that involves domestic reasons, either related to current agendas for education or to deep historical factors, and injunctions related to PISA's rationale and PISA objects.     

Perspectives on the Origins of Life in Science Textbooks from a Christian Publisher: Implications for Teaching Science

This study analyzes six seventh grade Israeli mathematics textbooks, examining (1) the extent to which students are required to justify and explain their mathematical work, and (2) whether students are asked to justify a mathematical claim that is stated by the textbook or a mathematical claim that they themselves generated when solving a problem. Two different units of analysis were used to analyze two central topics in the seventh grade curriculum as follows: (1) equation solving in algebra and (2) triangle properties in geometry. The findings indicate that all six textbooks had considerably larger percentages of geometric tasks than algebraic tasks, which required students to justify or explain their mathematical work. Moreover, considerable differences were found among the six textbooks regarding the percentages of tasks that required students to justify and explain in both topics, but more so with the algebraic topic. Analysis of whether the textbook tasks required students to justify a mathematical claim that is stated by the textbook or a mathematical claim that the students themselves generated also revealed substantial differences among the textbooks. These findings are discussed, as well as the research methods used, in light of relevant literature.     

Foreign direct investment and technological capabilities in Brazilian industry

The purpose of this paper is to make a contribution to a further understanding of the implications of the growing presence of foreign affiliates for deepening technological capabilities (TCs) in Brazilian industry. It proposes a TC classification that emphasises the distinction between the use and generation of knowledge and presents a methodology for composing TC proxies by means of an innovation survey database. The findings suggest that both foreign and domestics firms have accumulated substantial capabilities for using existing technology, but only shallow capabilities for locally generating technologies. However, foreign affiliates score higher than their local counterparts in more complex capabilities, confirming their centrality in the Brazilian learning system. This gives ground for urging the elaboration of strategic foreign direct investment (FDI) policies that strengthen and deepen local TCs.     

Of drama,dreams and desire: creative approaches to applied sex education in southern Africa

In the midst of a generalised HIV and AIDS epidemic in southern Africa, the argument for more coordinated and comprehensive youth sexual health interventions is intensifying. Yet the crucial question of how best to provide young people with these skills and knowledge remains a key challenge for policy-makers, researchers and practitioners in our region. Moreover, amongst the available literature on sex education in southern Africa, few authors have taken an applied perspective, to look at fresh approaches and tools with the potential to be implemented more broadly. This paper argues for a greater focus on concepts of masculinity and sexuality in the development of sexual health efforts in southern Africa. It aims to bridge theory and practice by advancing six promising approaches with the potential to create a suitable space and environment for participants to engage with these issues. Approaches include methods and tools currently being implemented in existing programmes, as well as ideas emerging from recent literature. Our paper is ultimately a call for further ‘out-of-the-box’ thinking to find more effective and creative practical ways of providing the sexual health education our region's youth urgently needs. It is also a call for more applied research, to better inform future sex education programmes in southern Africa.     

Young Children’s Mathematical Learning From Intelligent Characters

Children’s math learning (N = 217; M_age = 4.87 years; 63% European American, 96% college-educated families) from an intelligent character game was examined via social meaningfulness (parasocial relationships [PSRs]) and social contingency (parasocial interactions, e.g., math talk). In three studies (data collected in the DC area: 12/2015–10/2017), children’s parasocial relationships and math talk with the intelligent character predicted quicker, more accurate math responses during virtual game play. Children performed better on a math transfer task with physical objects when exposed to an embodied character (Study 2), and when the character used socially contingent replies, which was mediated by math talk (Study 3). Results suggest that children’s parasocial relationships and parasocial interactions with intelligent characters provide new frontiers for 21st century learning.     

Output-feedback binary adaptive control of MIMO systems using monitoring function

The problem of adaptive control design for multivariable linear time-invariant plants with unknown control direction is considered. A solution is proposed based on the SDU factorization of the high frequency gain matrix (HFG) and the monitoring function approach. The adaptation scheme is the binary model reference adaptive control (BMRAC) which utilizes parameter projection and sufficiently high adaptation gains. The signs of the leading principal minors of the HFG define the control directions, and the lack of knowledge of which is a major challenge in the multivariable framework. The role of the monitoring function is to monitor the output error transient and then provide the necessary changes of the adaptation gain signs to guarantee a stable adaptive control. In addition to proving the signal boundedness of the resulting closed-loop system, the output tracking error is shown to be asymptotically as well as exponentially practically stable, i.e., exponentially stable with respect to a small residual compact set of size inversely proportional to the BMRAC adaptation gain. The latter implies good transient properties of the output tracking error in contrast to conventional adaptive laws which only guarantee asymptotic stability but can lead to extremely slow error convergence. The extension of the proposed approach to matched disturbances is also briefly discussed following the classical paradigm of disturbance estimators. Numerical results with a visual servoing application illustrate the efficiency of the proposed method.     

Water-Based Aerobic Training Successfully Improves Lipid Profile of Dyslipidemic Women: A Randomized Controlled Trial

Purpose: This study aimed to investigate the effects of water-based aerobic training on the lipid profile and lipoprotein lipase (LPL) levels in premenopausal women with dyslipidemia. Method: Forty women were randomly assigned to: aquatic training (WA; n = 20) or a control group (CG; n = 20). The WA group underwent 12 weeks of water-based interval aerobic training twice a week at intensities ranging from 9 to 15 on the Borg Scale of Perceived Exertion. Total cholesterol (TC), triglycerides (TG), high- (HDL) and low- (LDL) density lipoprotein, TC/HDL ratio, LPL levels, and peak oxygen consumption (VO₂peak) were evaluated before and after 12 weeks in both groups. Results: The WA group elicited decreases in TC (9%; effect size [ES] = 0.69; 95% CI [0.05, 1.33]), LDL (16%; ES = 0.78; 95% CI [0.13, 1.42]), and the TC/HDL ratio (17%; ES = 1.13; 95% CI [0.46, 1.79]), as well as increases in VO₂peak (10%; ES = 0.64; 95% CI [0.002, 1.27]) and HDL (10%; ES = 0.28; 95% CI [?0.35. 0.90]), without significant changes in TG (ES = 0.16; 95% CI [?0.46, 1.79]) and LPL (ES = 0.36; 95% CI [?0.27, 0.98]) levels. In the CG, no statistically significant changes in any of these variables were found (TC, ES = 0.19, 95% CI [?0.43, 0.82]; LDL, ES = 0.22, 95% CI [?0.40, 0.85]; HDL, ES = 0.05, 95% CI [?0.57, 0.67]; TG, ES = 0.09, 95% CI [?0.53, 0.71]; TC/HDL ratio, ES = 0.20, 95% CI [?0.42, 0.82]; LPL, ES = 0.02, 95% CI [?0.60, 0.64]; VO₂peak, ES = 0.20, 95% CI [?0.42, 0.82]). Conclusion: Water-based interval aerobic training positively affected the lipid profile in premenopausal dyslipidemic women.     

Reconsidering the technologies of intellectual inquiry in curriculum design

This paper reports on the design and delivery of classroom pedagogies and students’ engagement with it in two different UK universities. Under the banner of curriculum design and Bourdieu's curriculum principles, the study set out to create modules that provided students with an interdisciplinary perspective on how the web is changing the way citizens live, interact and learn. Focusing on the idea that the web is becoming a tool of intellectual inquiry and an instrument of reproduction of knowledge inequality, the goal of this research was to transform knowledge practices by encouraging a learning habitus that relies on knowing how to learn rather than becoming ‘knowledgeable.’

The paper concludes that the Bourdieuian perspective on curriculum design still holds currency in the digital age, given that it shares an epistemology of practice similar to that advocated by a digital participatory culture. We also offer a critique to our approach, using Bourdieu's logic of practice to examine how education as a field displays (hidden) rules that students embody as their learning habitus. As students’ learning practices become doxified through their educational trajectories, learners find it difficult to engage with a curriculum that aims to diversify pedagogical structures and reflect a changing society.
