Examining the Relations Between Spatial Skills,Spatial Anxiety,and K‐12 Teacher Practice

Spatial skills are important for student success in STEM disciplines at the K‐12 educational level. Teachers' spatial skills and feelings about completing spatial tasks influence their teaching as well as their students' spatial learning. However, the relation between teachers' spatial skills and their spatial anxiety is not well understood. Here we investigated if teachers' spatial skills influence two kinds of small‐scale spatial anxiety: (a) anxiety for tasks involving visual imagery and (b) anxiety for tasks involving mental manipulations. In addition, we investigated if teachers' spatial skills in conjunction with their small‐scale spatial anxiety influence the integration of spatial practices, such as gestures and diagrams, into their teaching. Eighty‐two K‐12 teachers completed two subscales of small‐scale spatial anxiety, a measure of spatial skills, and a teaching activities questionnaire. Results indicate that teachers' spatial skills are negatively associated with their spatial anxiety for mental manipulation tasks, and positively associated with their use of spatial practices. These findings highlight the need to account for teachers' spatial skills when considering how to improve students' spatial learning.

Silent or Stealth Retractions,the Dangerous Voices of the Unknown,Deleted Literature

Retractions serve as one perspective of the publishing process, and can offer vast insight into the problems associated with basic research, with the traditional publishing platform, or with policies. Some established retraction guidelines exist, such as those established by the Committee on Publication Ethics, or COPE. This essay provides a perspective of stealth or silent retractions within the broader concept of retractions, and within the framework of the COPE retraction guidelines. The issue of opaque retraction notices, especially in the case of COPE members, as well as the prominence of questionable retraction policies among select “predatory” open access publishers, is emphasized. Select clear examples are provided.     

An Error is an Error… is an Erratum: The Ethics of not Correcting Errors in the Science Literature

This essay provides an unpalatable perspective on classifying the reluctance of authors, editors or publishers to correct their erroneous literature as being unethical. Authors who publish papers that carry errors and who take laurels for such publications, but who then fail to correct reported errors at a post-publication stage should be classified as unethical, and their act or irresponsibility as misconduct. Similarly, editors and publishers who fail to revise erroneous literature when claims are factually correct, independent of the volume of claims, are also in violation of their codes of conduct and professional responsibilities towards the scientific community and society. This essay provides a critical outlook on this issue which has begun to plague the post-publication movement in science, and which deserves urgent attention and focus.     

Global references,local translation: adaptation of the Bologna Process degree structure and credit system at universities in Cameroon

This article uses temporal comparison and thematic analytical approaches to analyse text documents and interviews, examining the adaptation of the Bologna Process degree structure and credit system in two sub-systems of education in Cameroon: the Anglo-Saxon and the French systems. The central aim is to verify whether such adaptation has replaced, re-enforced or modified existing practices. Secondly, the article analyses the factors that have influenced this adaptation. The results highlight the idea that education systems may demonstrate a level of awareness about global practices, but these practices are interpreted in their local contexts; thus, policy-makers ‘think globally but act locally’.     

Learning with immigrant children,families and communities: the imperative of early childhood teacher education

Abstract

This article reports on a longitudinal study spanning over 5 years, involving the design and implementation of an early childhood teacher education program model that engages a critical-ecological theoretical approach, a funds of knowledge perspective, and design-based methodology. This project aimed to promote equitable education for all children, and especially for young immigrant children encountering situations of oppression within the national and local educational contexts in Arizona. In this teacher education program, families, community members, researchers, pre-service teachers and teachers worked together to develop new modes of curricular activity, new spaces, new relationships, and new forms of movement among participants, as well as new circulations of literacy artefacts.
