The somatic marker as a “short cut” to verbal immediacy

This study examined the relationships between the somatic‐marker hypothesis, developed by Damasio (1994) as it relates to homophily and verbal immediacy in the classroom. Damasio has hypothesized that when particular events occur in one's life, there is a “memory” of that event in the brain. As a result, when a similar event occurs, the somatic marker recreates that first event. Students were provided three different scenarios about the first day of a communication class. In the scenarios, the instructor presented information about himself. One instructor provided only autobiographical, demographic data (the control). Another provided information hozu he had had difficulty with public speaking (the selfish marker). The third provided information about how the instructor had helped someone else who had difficulty in public speaking (the altruistic marker). The results indicated that while homophily differences were not significant, there was a significant difference between the control group and the altruistic marker.     

Effects of a Problem-based Structure of Physics Contents on Conceptual Learning and the Ability to Solve Problems

A model of teaching/learning is proposed based on a ‘problem-based structure’ of the contents of the course, in combination with a training in paper and pencil problem solving that emphasizes discussion and quantitative analysis, rather than formulae plug-in. The aim is to reverse the high failure and attrition rate among engineering undergraduates taking physics. A number of tests and questionnaires were administered to a group of students following a traditional lecture-based instruction, as well as to another group that was following an instruction scheme based on the proposed approach and the teaching materials developed ad hoc. The results show that students following the new method can develop scientific reasoning habits in problem-solving skills, and show gains in conceptual learning, attitudes and interests, and that the effects of this approach on learning are noticeable several months after the course is over.     

Factors Influencing Schoolchildren's Responses to a Questionnaire in Wildlife Conservation Education

Questionnaires are important tools for assessing attitudes regarding conservation issues. However, they are not easily comparable and their reliability has been insufficiently assessed. We examined factors influencing responses to open- and closed-ended questions about animal conservation to more than 600 schoolchildren (9 years old on average). We analysed the level of understanding, controllable (e.g. sample size) and less controllable factors (e.g. affectivity). Most children responded appropriately to the questions, but subtle changes in the phrasing influenced the answers. Affectivity towards endearing species and spontaneity also influenced the responses whereas small sample sizes (～50 children) provided relatively stable patterns. Overall, we suggest that standardization of questionnaires administered over large spatial and time scales is needed to accurately assess children's attitudes towards conservation issues.     

Public universities and the neoliberal common sense: seven iconoclastic theses

Neoliberalism has utterly failed as a viable model of economic development, yet the politics of culture associated with neoliberalism is still in force, becoming the new common sense shaping the role of government and education. This ‘common sense’ has become an ideology playing a major role in constructing hegemony as moral and intellectual leadership in contemporary societies. Neoliberal globalisation, predicated on the dominance of the market over the state and on deregulatory models of governance, has deeply affected the university in the context of ‘academic capitalism’. The resulting reforms, rationalised as advancing international competitiveness, have affected public universities in four primary areas: efficiency and accountability, accreditation and universalisation, international competitiveness and privatisation. There is also growing resistance to globalisation as top-down-imposed reforms reflected in the public debates about schooling reform, curriculum and instruction, teacher training and school governance. Many question whether neoliberal reforms attempt to limit the effectiveness of universities as sites of contestation of the national and global order and thus undermine the broader goals of education. Neoliberal reforms have limited access and opportunity along class and racial lines, including limiting access to higher education through the imposition of higher tuition and reduced government support to institutions and individuals.     

ABRETE SESAMO: Investigación sobre TV infantil

RESUMEN

En 1977 el equipo de estudios para la programación infantil de Televisión Española comenzó a trabajar en un proyecto orientado a elaborar un programa infantil dirigido a un público de 3 a 6 años de un nivel socioeconómico deprimido. Se tomó como modelo, “Sesame Street”, un programa de una cadena americana con unos objetivos pedagógicos determinados emitiéndose en este país. El trabajo que se presenta es una investigación formativa llevada a cabo para proporcionar a esta nueva serie una orientación teórico-práctica lo más acorde posible con la realidad del país.

Fue por tanto necesario realizar algunos cambios e incluir temas ausentes en el programa americano, pero considerados importantes aquí. Finalmente, se describe el esquema ideal de metas pedagógicas de este nuevo programa denominado Barrio Sésamo.     

Diferencias evolutivas en procesamiento de textos mediante una tarea de ordenación de frases

Resumen

Este estudio presenta los resultados de una investigación en la que se describen algunas diferencias evolutivas en el procesamiento de la prosa expositiva. Treinta y cinco chicos de diferentes edades, 12 de 5.^o de E.G.B., 12 de 8.^o de E.G.B, y 11 de 3.^o B.U.P y F.P. (10, 13 y 16 años respectivamente), realizaron una tarea de ordenación de frases para formar un texto coherente. Había un total de tres textos de tipo expositivo, constando cada uno de seis oraciones. Se tomaron varias medidas en cada texto: una primera de ordenación global, otra de supraordenación, una tercera de coherencia local (conexiones entre seis pares de frases), y una última medida de errores de conexión. Los resultados confirman una clara tendencia evolutiva en todas las medidas empleadas. Finalmente, se discuten los resultados relacionándolos con otros estudios que analizan el desarrollo de estrategias de comprensión, y se comentan varias repercusiones educativas del trabajo, así como algunas cuestiones abiertas.     

Grade level, study time, and grade retention and their effects on motivation, self-regulated learning strategies, and mathematics achievement: a structural equation model

The present study complements previous research findings with new data to improve our understanding of the relationship between motivational variables and academic performance in math mediated by self-regulated learning (SRL). A structural equation model with predictor (i.e., grade retention, grade level, and study time), process (i.e., perceived usefulness of SRL strategies, self-efficacy for the use of SRL strategies, and reported use of SRL), and product variables (i.e., academic achievement in mathematics) is proposed. The model was analyzed in two samples of data (calibration and validation samples). The first sample served to fit and respecify the model, and the second one was used to analyze the consistency of the findings of the first sample. A sample of 756 middle school Portuguese students participated in the current study. The results indicate that SRL is positively and significantly related to academic achievement and that the latter is, in turn, powerfully determined by perceived usefulness and self-efficacy, although students’ reported use of SRL strategies decreases from 7th to 9th grades. Self-efficacy and perceived usefulness of SRL strategies were also found to decrease as grade retention increased. These results are discussed with regard to the relevance of self-efficacy and perceived usefulness of SRL strategies in increasing academic achievement.     

The Engagement of Older People in Civil Society Organizations

This article reviews recent international literature on the opportunities and restrictions experienced by older people to act as volunteers in civil society organizations. Our aim was to develop a conceptual framework applicable to the European ageing society. This aim was pursued through a computerized database search focused on studies analyzing the individual, organizational, and/or societal levels. Findings show that senior volunteers are characterized by “younger” age, good health, and a high level of both educational and socioeconomical status. Volunteers are involved mainly in religious organizations as well as in social and personal care, while main barriers are represented especially by ageist practices. The review shows that the debate on this topic has been barely developed in Europe, both from an individual and societal point of view. Therefore, European countries might take advantage from experiences made in other contexts, but the identification of how this can occur requires further and more specific cross-national research.     

Coherence estimate between a random and a periodic signal: Bias, variance, analytical critical values, and normalizing transforms

The present work deals with recent results on the sampling distribution of the magnitude-squared coherence (also called just coherence) estimate between a random (Gaussian) and a periodic signal, in order to obtain analytical critical values, alternative expressions for the probability density function (PDF) as well as the variance and bias of the estimate. A comparison with the more general case of coherence estimation when both signals are Gaussian was also provided. The results indicate that the smaller the true coherence (TC) values the closer both distributions become. The behaviour of variance and bias as a function of the number of data segments and the TC is similar for both coherence estimates. Additionally, the effect of a normalizing function (Fisher's z transform) in the coherence estimated between a random and a periodic signal was also evaluated and normality has been nearly achieved. However, the variance was less equalized in comparison with coherence estimate between two Gaussian signals.
