Students–exhibits interaction at a science center

In this study we investigate students' learning during their interaction with two exhibits at a science center. Specifically, we analyze both students' procedures when interacting with exhibits and their understanding of the scientific concepts presented therein. Bernstein's theory of pedagogic discourse (1990, 2000) provided the sociological foundation to assess the exhibit–student interaction and allowed analysis of the influence of the characteristics of students, exhibits, and interactions on students' learning. Eight students (ages 12ndash;13 years of age) with distinct sociological characteristics participated in the study. Several findings emerged from the results. First, the characteristics of the students, exhibits, and interactions appeared to influence student learning. Second, to most students, what they did interactively (procedures) seems not to have had any direct consequence on what they learned (concept understanding). Third, the data analysis suggest an important role for designers and teachers in overcoming the limitations of exhibit–student interaction. © 2006 Wiley Periodicals, Inc.

The Bologna process and the search for excellence: between rhetoric and reality,the emotional reactions of teachers

ABSTRACT

There has been an overall change in higher education towards the achievement of outstanding patterns of quality and excellence that assure competitiveness at a global scale. Teachers feel the pressure of official regulations for achieving quality and excellence, based on questionable concepts of quality that do not take into account the experience and beliefs of teachers and lead to emotional states that may promote or hinder adjustment to changes.

The present study used a categorical content analysis to capture the emotions that twelve university teachers associate with the changes experienced and with the pursuit of quality emphasized in Portugal by the Bologna Process. The results show that participants revealed mixed emotions regarding change. Students elicit mostly positive emotions, whereas bureaucracy, marketization and career changes generate negative emotions that impede the quest for quality, although in a minority of participants they prompt resilience that stimulates engagement in quality.     

Teacher's experiences in PBL: implications for practice

Project-Based Learning (PBL) has been implemented in the first year of the Industrial Engineering and Management programme at the University of Minho, Portugal, since 2004/2005. The purpose of this paper is to analyse and discuss teachers' experiences in PBL in this programme and to explore its implications for student learning and for teaching practices in higher education. For data collection, the research method used was written narratives to these teachers, at the end of the PBL semester. Findings suggest that teachers express a positive view of PBL as a learning approach. They identify student motivation and engagement, along with a better understanding of the application of concepts in real-life situations, as important outcomes of the project for students. Besides this, teachers also highlight the importance of the development of transversal skills by students throughout the project. Recommendations for future work and implications for practice will also be discussed.     

A questionnaire for listening to students’ voices in the assessment of teaching quality in a classical medical school

The purpose of this study was to develop a teaching quality assessment questionnaire and assess its reliability by using it with a sample of first‐year medical students. Principal components analysis with varimax orthogonal rotation resulted in the development of a 12‐item, two‐component tool, adequate for use in lectures and small‐group sessions. The two components were named ‘curriculum’ and ‘relationship’. The Cronbach coefficient alpha values indicated high reliability and internal consistency. According to the results obtained this teaching quality scale is a reliable measure and may be useful in identifying themes in disciplines and among teachers that may benefit from some professional development. Amongst its advantages is that it can be used with an optical reading tool.     

Farmers’ Visions on Soils: A Case Study among Agroecological and Conventional Smallholders in Minas Gerais,Brazil

Abstract

Purpose: Why do farmers not take better care of their soils? This article aims to give insight into how farmers look at soil quality management.

Design/methodology/approach: It analyses diverse land management practices and visions on soils and soil quality of ten agroecological and 14 conventional smallholder farmers in Araponga, Minas Gerais, Brazil. As agroecological farming (that is, managing soils with minimum use of external inputs) requires more complex knowledge, it is assumed that agroecological farmers would be more knowledgeable on soils compared to conventional farmers. This case study tests the hypothesis that differences in land management practices between agroecological and conventional farmers can be explained by differences in their knowledge on soils.

Findings: The hypothesis turned out to be faulty: agroecological and conventional farmers do not differ in what they know about soils, but how they use their knowledge in their farming strategy. Both groups of farmers have different but rational farming strategies.

Practical implications: Designing policies and measures to make farming more environmentally friendly and more sustainable as two-way knowledge exchange between farmers and science (and not as one-way knowledge transfer from science to farmers), to benefit from vital and context-based farmers’ knowledge and to ensure successful implementation of more sustainable land management practices.

Originality/value: By analysing farmers’ visions on soil quality management and farming strategies, this study shows that farmers’ knowledge is valuable for farmers, for scientific knowledge on soil quality management and for policies which are to be effective and adapted to the local environment.     

The impact of a Curriculum for Resilience Promotion in Deaf Children and Adolescents

Resilience is an interactive process involving internal skills that should be promoted, especially in the early stages of development. This study aims to adapt and implement two themes from the European Curriculum for Resilience Promotion – RESCUR, namely, ‘Developing Communication Skills’ and ‘Establishing and Maintaining Healthy Relationships’, for deaf and hard-of-hearing (DHH) students. The study included 37 children and adolescents from three Portuguese regions and its impact was evaluated through the perspectives of the students, their guardians and their teachers. Each 90-minute session was implemented weekly. The sessions followed the RESCUR curriculum structure with necessary adaptations to the mindfulness activities, stories, role-play and worksheets. The mean scores increased from pre- to post-intervention assessment on all instruments, namely, KIDSCREEN-10 (children/adolescents), KIDSCREEN-10 (guardians) and CYRM-28 (teachers). The implementation of adapted curricula promoting resilience seems to be beneficial to DHH children, allowing the development of specific resilience-associated skills, and thus enhancing health, well-being and quality of life.     

Students’ expectations of the economic returns to college education: results of a controlled experiment

We report the results of an experiment designed to elicit students’ subjective beliefs about the economic returns to college education. An important feature of our experimental design is the inclusion of financial incentives for accurate reporting. We also consider the extent to which individuals’ beliefs about their own returns differ from their beliefs about the returns for others. The evidence shows that students do have a self-enhancement tendency, and this finding cannot be attributed to previously uncontrolled order effects. The evidence also indicates that there is no significant difference between beliefs elicited using hypothetical surveys or real financial incentives in the elicitation procedure. This finding suggests that economists’ reluctance to gather subjective data on earnings expectations may not be warranted.     

Brazil Meets the Global Challenge: IT Policy in a Postliberalization Environment

Since the early 1990s, Brazilian IT policy has changed substantially from greenhouse protectionism in selected segments of the market to a more liberal regime. This article analyses the impact of liberalization on IT equipment production, diffusion, employment, and foreign trade. There were both benefits and setbacks, depending on the aspect analyzed. Users benefited from greater access to imported equipment, which could eventually contribute to productivity growth in the overall economy.On the negative side, there was a loss of local linkages with internal sources of components, technology, and employment. The article concludes that the future of the Brazilian IT industry does not seem to be in commodity hardware production. Rather, it lies in design- and engineering-intensive applications. Such "production close to use" can spur domestic use as well as create business opportunities for domestically owned companies in markets not dominated by foreign multinationals.
