Patterns for reform in American teacher education

Public accountability in America has led to the reform of teacher preparation. A competency-based fieldcentered approach is emerging. The two major processes for achieving reform are the development of alternative teacher education institutions and the conversion of existing ones. The political and educational aspects of each process are considered.

Résumé La réforme de la formation des maîtres aux Etats-Unis a été amenée par le développement de l'idee de responsabilité publique. On remarque l'élaboration d'une approche fondée sur la compétence pratique. Les deux principaux facteurs de cette réforme sont le développement d'un nouveau genre d'établissements pour la formation des maîtres et la transformation de ceux qui existent actuellement. Cet article fait l'exposé des aspects politique et éducationnel de chacun de ces facteurs.

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.     

Open-field behavior of young chicks (Gallus gallus): Antipredatory responses,social reinstatement motivation,and gender effects

Two experiments investigating sex differences in the open-field behavior of young chicks are reported. In the first experiment, ambulation latencies of 10-day-old male and female chicks in a novel environment were measured. Half of the chicks were kept in social isolation for 2 days prior to testing; the other half were socially reared until tested. Results showed that in socially reared chicks ambulation latencies were significantly higher in males than in females, whereas in isolation-reared chicks there were no significant sex differences. In the second experiment, latencies of ambulation were measured in socially reared 10-day-old chicks placed in a novel environment with or without a visible predator (i.e., a human being). Sex differences were evident in both conditions, with males showing higher ambulation latencies than females. It is argued that sex differences in open-field behavior of chicks may be due to a stronger motivation for social reinstatement in females, which reduces the usual antipredatory reactions of chicks placed in a novel environment.     

The violence of peace and the role of education: insights from Sierra Leone

Research on peacebuilding has mushroomed over the last decade and there is a growing interest in the role of education in supporting peacebuilding processes. This paper engages with these debates, UN peacebuilding activities and the location of education initiatives therein, through a case study of Sierra Leone. In the first part, we explore the complex and multi-dimensional nature of violence in post-conflict Sierra Leone. In the second, we critically address the role of education in the conflict and post-conflict period, highlighting education’s centrality as a catalyst to conflict, and then reflect on the failure of the post-conflict reconstruction process to adequately transform the education system into one that could support a process of sustainable peacebuilding. Finally, we conclude by exploring the ways that greater investment and focus, both financial and human, in the education sector might, in the long term, better contribute to a sustainable and socially just peace.     

If star scientists do not patent: The effect of productivity, basicness and impact on the decision to patent in the academic world

We run an Event History Analysis on a sample of Italian researchers in the field of Materials Science, aiming at understanding how the characteristics of the research trajectories followed by scientists in academia affect their opportunities to do development of industrial applications. Results of our estimates suggest that all measures of academic performances have a dual effect, although different in magnitude. Scientists that are moving along applied research trajectories find it easier to produce industrial applications than their colleagues engaged in the quest for very fundamental understanding. We interpret our results by suggesting that, for the former, more academic research results in more exploitable results, hence in more chances to patent; for the latter, more academic research makes it just more unlikely that they will find the time to produce industrial applications. Similar results apply for the low versus high research impact.

Science teachers' pedagogical content knowledge development during enactment of socioscientific curriculum materials

The purpose of this study is to provide insight into short-term professionalization of teachers regarding teaching socioscientific issues (SSI). The study aimed to capture the development of science teachers' pedagogical content knowledge (PCK) for SSI teaching by enacting specially designed SSI curriculum materials. The study also explores indicators of stronger and weaker development of PCK for SSI teaching. Thirty teachers from four countries (Cyprus, Israel, Norway, and Spain) used one module (30–60 min lesson) of SSI materials. The data were collected through: (a) lesson preparation form (PCK-before), (b) lesson reflection form (PCK-after), (c) lesson observation table (PCK-in-action). The data analysis was based on the PCK model of Magnusson, Krajcik, and Borko (1999). Strong development of PCK for SSI teaching includes “Strong interconnections between the PCK components,” “Understanding of students' difficulties in SSI learning,” “Suggesting appropriate instructional strategies,” and “Focusing equally on science content and SSI skills.” Our findings point to the importance of these aspects of PCK development for SSI teaching. We argue that when professional development programs and curriculum materials focus on developing these aspects, they will contribute to strong PCK development for SSI teaching. The findings regarding the development in the components of PCK for SSI provide compelling evidence that science teachers can develop aspects of their PCK for SSI with the use of a single module. Most of the teachers developed their knowledge about students' understanding of science and instructional strategies. The recognition of student difficulties made the teacher consider specific teaching strategies which are in line with the learning objectives. There is an evident link between the development of PCK in instructional strategies and students' understanding of science for SSI teaching.     

Capital,inequality and education in conflict-affected contexts

Abstract

Piketty’s Capital in the Twenty-first Century has brought the issue of inequality to the centre of political debate. This article explores contemporary research on the relationship between education and inequality in conflict-affected contexts with a view to seeing how Piketty’s work speaks to these issues as a field of research and practice. The article provides a critique of Piketty’s approach, arguing for a broader, interdisciplinary and holistic approach to exploring and addressing inequality in education in conflict-affected contexts in their multiple economic, cultural and political dimensions. In doing so the article also lays out an analytical framework inspired by cultural political economy for researching education systems in conflict contexts which seeks to go beyond narrow human capital framings of education and address the multiple potential of education to promote sustainable peace and development in and through education.
