Algunas reflexiones sobre la didáctica de la lengua oral

El lenguaje oral es tanto medio prioritario de la comunicación en el aula como contenido de la enseñanza de la lengua. En este artículo se pasan revista desde ambas perspectivas a los objetivos y prácticas educativas de la lengua oral, proporcionando una base de reflexión que destaca aspectos con frecuencia olvidados de la herramienta principal de la educación.     

A Research-Informed Instructional Unit to Teach the Nature of Science to Pre-Service Science Teachers

In this paper we discuss the foundations and process of design of a research-informed instructional unit aimed for pre-service science teacher education. The unit covers some key ideas on the nature of science (around methodology, theory change, scientific inference and explanation, values, gender issues) anchoring them in a well-known episode from the history of science—the ‘discovery’ of radium by the Curies. Such episode is mainly examined as reconstructed in the 1997 French commercial film ‘Les Palmes de Monsieur Schutz’. Pre-service science teachers are required to solve three tasks, individually and in small groups; those tasks are respectively centred around: (1) the distinction between ‘discovering’ and ‘inventing’; (2) scientific modelling via abduction; and (3) the extended hagiographic treatment of the figure of Madame Curie. Plenary debates around the tasks aim at acquainting pre-service science teachers with some powerful concepts of twentieth century philosophy of science.     

Latinx* popular culture imaginaries: examining Puerto Rican children’s social discourses in interpreting telenovelas

Abstract

In this paper, we present a collaboration project within one urban Puerto Rican classroom, focused on constructing a critical literacy inquiry curriculum grounded in the students’ out-of-school literacy practices in their communities, including their experiences with media and popular culture. We focused on a critical literacy and media inquiry unit centered on the students’ self-selected subject of the telenovela. Here, we examine one student’s work to highlight two overarching findings: (1) the visibility of the students’ complex understanding of the media landscapes in telenovelas, particularly the construction of dominant social discourses across telenovela worlds, and (2) the ways that bringing children’s mediatized cultural imaginaries in their creative work supports an approach to literacy in classrooms, where explorations of discourses of power emerge from the students’ knowledge. In order to articulate how children actively examine and construct discourses across multiple social worlds, we examine these findings using the Four Resource Model, and elements of discourse analysis, as theoretical and analytical frameworks, focusing on the construction of identities, worlds and meanings in relation to the social discourses of telenovelas.     

Education for sustainability in university studies: A model for reorienting the curriculum

A decisive factor for achieving a culture of sustainability is university training for future professionals. The aim of this article is to bring new elements to the process of reorienting university studies towards sustainability. Presented here is the ACES model (Curriculum Greening of Higher Education, acronym in Spanish), which is the result of a project involving a network of 11 European and Latin American universities. The methodology of the project is based on participatory action research. The ACES model is defined by 10 characteristics, detailed in this article, which can orientate a diagnosis of the level of curriculum greening and the design and application of the strategies and actions in order to facilitate incorporating the sustainability dimension in higher education. The potentialities and limitations found are also discussed. The ACES model has started a process for reorienting higher education studies towards sustainability.     

Effect of argumentative goals in the quality of argumentative dialogue and written argumentation / Efecto de la consigna argumentativa en la calidad del diálogo argumentativo y de la argumentación escrita

The inclusion of argumentative practices in classrooms as an epistemic tool to foster learning and reasoning has become widespread. However, studies on argumentation show that not all kinds of argumentation are equally effective in fostering this potential, and that argumentative goals are determining factors in the argumentative discourse — in particular, persuasive and deliberative goals, the latter posited as being the ones with the greatest epistemic potential. Eighty students in the Master in Secondary Teacher Training took up positions on an energy dilemma and wrote two argumentative texts, before and after a dialogue with a classmate who defended the opposite thesis. Of the total of 40 dyads, 21 conversed with a persuasive goal and 19 with a deliberative goal. The results show that the dialogue had a positive effect on the argumentative quality under both conditions. However, in the consensus group, the bias of the post-text diminished while meta-statements and counterarguments increased. A case study of one dyad under each condition illustrates these differences.     

Environmental correlates of total and domain-specific sedentary behaviour in young people. The UP&DOWN study

This study investigated the associations between the characteristics of the nearby physical environment with the total and domain-specific leisure-time sedentary behaviour (SB) in young people. The study included 1578 youth (9–18 years) from the UP&DOWN study. Total leisure-time SB was objectively-assessed by accelerometers. Participants self-reported the time spent during leisure-time in different domains of SB (i.e. screen-based, educational-based, social-based, and other-based SB). Information regarding the basic characteristics of the house, the perceived neighbourhood environment, the amount of physical activity facilities, equipment and materials attainable at home, and the media equipment available at home and in the own bedroom was collected. Linear mixed models were performed, including school and city as random effects. The availability of yard was related to lower total SB and time spent surfing the Internet in boys, but not in girls. More favourable perceived neighbourhood environment was associated with lower total SB and time spent playing video games in girls, but not in boys. The amount of physical activity materials at home was negatively associated with screen-based SB, while the availability of a computer in the own bedroom was positively related to the time spent surfing the Internet in boys and girls. The number of televisions at home and having a computer in the own bedroom was associated with lower time in educational-based SB in boys and girls, respectively. Increasing the number of PA materials at home and decreasing the number of TVs at home and the availability of a computer in the bedroom could improve SB profiles of youth.     

Exploring the relationship among learning patterns,personality traits,and academic performance in freshmen

Providing information about how 1st-year students learn may help colleges plan actions aimed at increasing students' persistence in higher education programs. This research aims to assess 1st-year students' academic performance, using a path analysis to establish inter-correlations among students' personality traits, learning patterns, high school achievement, and objectively measured outcomes. Participants included 509 freshmen from different academic disciplines. Results show a causality relations model in which Conscientiousness positively influences Sequential and Precise learning patterns as well as academic performance. The path model also confirms Extraversion as a negative antecedent of the Technical learning pattern. It is argued that knowing students is a primary step to putting them in a position to become an active part of the learning process.     

The acquisition and transfer of knowledge of electrokinetic-hydrodynamics (EKHD) fundamentals: an introductory graduate-level course

Relevant engineering applications, such as bioseparation of proteins and DNA, soil-cleaning, motion of colloidal particles in different media, electrical field-based cancer treatments, and the cleaning of surfaces and coating flows, belongs to the family of ‘Applied Field Sensitive Process Technologies’ requiring an external field to move solutes in a fluid within a fibrous (or porous) domain. This field incorporates an additional variable that makes the analysis very challenging and can create for the student a number of new problems to solve. A graduate-level course, based on active-learning approaches and High Performance Learning Environments, where transfer of knowledge plays a key role, was designed by the Chemical Engineering Department at Tennessee Technological University. This course, where the fundamentals principles of EKHD were taught to science, engineering and technology students was designed by the Chemical Engineering Department at the Tennessee Technological University, Cookeville, TN. An important number of these students were able to grasp the tools required to advance their research projects that led to numerous technical presentations in professional society meetings and publications in peered-reviewed journals.     

Epistemological Foundations of School Science

Based on a synthesis of contributions from differentauthors, we present a theoreticalframework that provides some foundations for schoolscience, and we define someresearch problems. We start from what is already knownabout students' models andcognition in order to construct proposals of didacticalintervention. The cognitive modelof science, developed in the philosophy of science throughstudying scientists' activity,has allowed us to propose an analogous model for schoolscience in which experimentationand language play the key roles. We emphasise the relativeindependence of school scienceand scientists' science.     

Correlates of sedentary behaviour in youths with Down syndrome: the UP&DOWN study

The aim of this study was to identify potential correlates of sedentary time and television (TV) viewing time in youth with Down syndrome (DS). A total of 98 adolescents with DS (63 males) aged 11–20 years old participated in this study. Total sedentary time was measured using accelerometers, while total TV viewing time and potential correlates were measured using proxy-report questionnaire. Analyses of covariance and a stepwise multiple linear regression were performed to examine correlates of total sedentary time and total TV viewing time. Different potential correlates were associated with total sedentary time (mother age, mother TV viewing time, perceived benefits of physical activity, birth order and having nearby shops in the neighbourhood) and total TV viewing time (father TV viewing time, TV viewing time with parents, family dietary habits during watching TV and weekend days time indoor). The identification of correlates associated with sedentary behaviour, principally those considered modifiable such as social and environmental factors, may contribute to development strategies to decrease sedentary behaviour in adolescents with DS and consequently promote a healthier lifestyle.
