Projects in a sixth‐grade classroom: entering a bumpy but promising road

In this article the possibility of developing authentic project work in a sixth‐grade classroom of a Venezuelan school is explored, by means of action research (AR) methodology. Two AR cycles with two different projects were carried out. Data were collected via teacher researcher, co‐researcher and student journals, and also by means of audio and video recordings, interviews with students, and compilation of classroom products. Data were interpreted using a narrative presentation and also applying five categories, only one of which is analyzed in this paper. Results show that on the one hand student participation increased in all stages of the project work. On the other hand, students encountered some difficulties carrying out empirical research activities and also relating them to theoretical content, although progress in this regard was made. Additionally, communication should have departed more from mere repetition, although some teams were able to try more formative approaches. It was corroborated that school facilities must be improved in order to promote better project work. AR proved fruitful as a way to produce changes and generate practical and reflexive contributions.     

CONCEPT MAPPING: AN ALTERNATIVE STRATEGY FOR EVALUATION

Concept maps are proposed as an alternative tool for evaluation in higher education and examples of concept maps, drawn by college students performing evaluation tasks, are presented in the areas of physics and literature.     

Assessing Science Teaching Explanations in Initial Teacher Education: How Is This Teaching Practice Transferred Across Different Chemistry Topics?

Research in Science Education - One of the core practices of science teachers is the construction of science teaching explanations. These explanations serve to clarify concepts, procedures, facts,...     

Identity Production in Figured Worlds: How Some Multiracial Students Become Racial Atravesados/as

Using Holland et al.’s (Identity and agency in cultural worlds, Harvard University Press, Cambridge, 1998) theory of identity and their concept of figured worlds, this article provides an overview of how twenty-five undergraduates of color came to produce a Multiracial identity. Using Critical Race Theory methodology with ethnographic interviewing as the primary method, I specifically focus on the ways in which Multiracial figured worlds operate within a racial borderland (Anzaldúa in Borderlands: La Frontera—The New Mestiza, Aunt Lute Books, San Francisco, 1987), an alternate, marginal world where improvisational play (Holland et al. in Identity and agency in cultural worlds, Harvard University Press, Cambridge, 1998) and facultad became critical elements of survival. Participants exercised their agency by perforating monoracial storylines and developed a complex process of identity production that informed their behaviors by a multifaceted negotiation of positionalities. I end by focusing on implications for urban education that can be drawn from this study.     

Effect of a pilot multi-component intervention on motor performance and metabolic risks in overweight/obese youth

This study evaluated the effect of a multi-component intervention on motor performance (MP) and metabolic risk markers (MRM) in overweight/obese youth. A secondary aim was to examine whether changes in MP are associated to changes in MRM. A 3-month multi-component intervention was performed, consisting of physical exercise sessions (twice/week;1h), nutritional education sessions (once/month), and parental support (twice/week). The sample included 35 volunteers (7–13 y.o), allocated to intervention (INT, n = 17) and control (CONT, n = 18) group. Variables were measured pre (T0) and post intervention (T1). Fasting blood samples were analyzed for MRM. MP tests included the measurement of health related physical fitness components and motor coordination performance (KTK battery). To assess food intake, a 24-hour recall diary was used. GLM-ANCOVA was performed. Standardized scores were calculated for the outcome variables, and multilinear regressions were applied to analyze associations between the key variables. INT group showed improvements in MP, glycolytic and hepatic profiles. After adjustments for MVPA, SB, total intake and maturational stage, negative associations between %ΔMP and %Δglycolytic (β = -.424; 95%CI:-0.343:-0.022), and %Δhepatic scores (β = -.382 95%CI:-0.001:-0.009) were observed. The intervention produced a moderate-to-high effect on the MP and some MRM. Changes in MP were inversely associated with changes in glycolytic and hepatic markers.     

Making Design Education (Even More) Complex: Exploring Complexity for an Amplified Mindset of Design

An Amplified Mindset of Design (AMD) has emerged from recent research on emerging design practices, as designers are once again re‐inventing their identity to include an adaptability to uncertainty and paradox. However, this is not yet visible in what design education offers. As designers intervene in complex contexts and embrace participatory, collaborative and interdisciplinary practices informed by strong ethical and sustainability concerns, design education must adjust and expand its scope to include, for example, collaboration, cross‐cultural and interdisciplinary skills, and a way of being in the world through design. In this article, I argue for the formal introduction and exploration of social complexity in design education to assist the development of an AMD in design students. Boundaries, dependence on context, edge of chaos, emergence and organisation were identified as key qualities of complex systems to introduce to students. Embodiment and visualisation techniques were used as the most appropriate vehicles for such an endeavour. In this article, I discuss the results of a qualitative research informed by action research in which I explore ways of teaching complexity to design students. The inquiry was driven by the following core research question: How can complexity can be taught in design education using visual and embodiment methods to encourage the development of an Amplified Mindset of Design?     

Growth,functional capacities and motivation for achievement and competitiveness in youth basketball: an interdisciplinary approach

The interaction of multiple influences on the path to sport success is not yet fully understood by sport scientists. In this study, we examined variation in body size, functional capacities and motivation for achievement, competitiveness and deliberate practice of youth basketball players associated with differences in biological maturity status, chronological age and years of training experience. Reflecting the importance of interactive effects, we examined the relationships between the psychological variables and functional capacities. Fifty-eight male basketball players aged 9.5 to 15.5 years were considered. Variables included chronological age, estimated age at peak height velocity, stature, body mass and sitting height by anthropometry; the Work and Family Orientation and Deliberate Practice Motivation Questionnaires were also used. Finally, the Line Drill test and Yo-Yo Intermittent Recovery level 1 (Yo-Yo IR1) tests were used as functional capacities indicators for basketball. Variance components models derived from series of multilevel linear regression models revealed a substantial variation by maturity status for body size, functional capacities indicators, mastery and will to excel. The influence of estimated maturity status on mastery and will to excel was independent of age and years of experience. In contrast, no relationships were observed between psychological variables and functional capacities indicators. We conclude that growth-related changes are relevant to understanding players´ motivations for achievement, competitiveness and deliberate practice. This should be of interest to those involved in the selection and development of youth basketball players.     

Understanding teachers' attitudes to change in a Logomathematics environment

We describe the views and attitudes of a group of Portuguese primary teachers as they unfolded during a course aimed at introducing a Logo-mathematical culture. We identify what was at stake for them in interacting with such a culture by focusing on sketches of two participants. The study had threefold aims: to describe and analyse attitudes towards mathematics and mathematics teaching; to examine the interactions between participants' attitudes and their activities on the course; and to investigate what kinds of influences the course had on their attitudes.     

Human capital intensity in technology-based firms located in Portugal: Does foreign ownership matter?

This paper contributes to the scarce empirical literature on the impact of foreign ownership on human capital intensity. New evidence is provided, based on a comprehensive, large-scale survey of technology-based firms located in Portugal. The key findings are that: (1) foreign ownership directly (and significantly) impacts a firm's general human capital (education); (2) foreign ownership indirectly (and significantly) impacts a firm's specific human capital (skills); (3) the total impact of foreign ownership on a firm's human capital intensity is higher for education- (general) than for skills- (specific) related human capital intensity. Giving the critical importance of both FDI and human capital development for an ‘intermediate’ economy like Portugal (lagging behind in terms of human capital stock, and seeming to have lost part of its attractiveness as an FDI location), the paper discusses related policy implications. It is believed that our results and conclusions may be useful for other countries facing similar challenges.
