It is widely accepted that to be scientifically literate one needs to have the ability to make thoughtful decisions about socioscientific issues (SSI). This includes critical assessment of scientific claims and arguments involved. In this study we asked 89 science education students with substantial academic qualifications in science, working in groups of two and three, to assess the reliability of scientific claims in an article of their own choice, but related to a socioscientific issue, and to present their evaluation in a short text. In analyzing the students' texts, we focused on the criteria they had explicitly and implicitly used in their evaluations. Through a qualitative analysis, we identified 13 different criteria focusing on empirical and theoretical adequacy, completeness of presented information, social aspects, and manipulative strategies. An inspection of the students' evaluations revealed that they drew upon knowledge of possible institutional interests, different signs of competence and an appreciation of concurrent expert views, but also methodological norms in science, specialized content knowledge, and an appreciation of evidence and disclosure of sources. The number of criteria used and the quality of their application varied, indicating that critical examination of texts with a science dimension needs to be emphasized in science teacher education. © 2006 Wiley Periodicals, Inc.

Current literature suggests that while teacher educators perform a multitude of complex roles, they receive very little preparation or possibilities for professional development to fulfil these roles. As a result, they need to acquire relevant knowledge and skills after taking on the position of teacher educators. Therefore, it is important to learn what skills and knowledge teacher educators need and how they acquire such skills and knowledge throughout their career. The purpose of the study is to describe the professional development needs and activities of 61 teacher educators across six national jurisdictions (

In order to increase student performance, governments stress the importance of standardization for teaching which is seen as a threat to teachers' professionalism. In this small-scale study we investigated the way teachers use their professional space in these changing circumstances. We studied eighteen cases of secondary education teachers indepth, using observations, interviews, and storylines. Our analyses revealed two types of trajectories which can be characterized by bounded and contested agency. In both trajectories the importance of personal factors and environmental factors were acknowledged. Insights into the relation between perceived space and agency can promote our understanding of teacher professionalism.
