The present study explored the relationships of preservice teachers’ levels of commitment to teaching and their beliefs and perceptions of teaching as a career. Participants were undergraduate students enrolled in a teacher education program at a major university in the southeast. Sixty‐seven preservice teachers completed a survey in which they rated the importance of 20 factors for influencing their choice of career. Additionally, among the survey respondents, nine students were selected from three groups of preservice teachers for in‐depth interviews: (1) students who were currently considering teaching as a career choice, (2) students who were undecided about their future teaching career, and (3) students who were no longer considering teaching as a career. Overall, findings from this study revealed that preservice teachers’ understanding of their goal of becoming teachers and interpretations of their motivation for teaching were unique, yet the types of influences on their career choices were similar across participants’ stories.     

Change agency as a way of promoting pedagogical development in academic communities: a longitudinal study

ABSTRACT

In the face of organizational transformations, academics are given a role as informal ‘change agents’ in their discipline-specific communities of practice (DCoP). Simultaneous participation in pedagogically oriented communities of practice (PCoP) enables them to promote pedagogical development through brokering at community interfaces. This empirical study explores academics’ experiences of acting as informal change agents at the interfaces of DCoP and PCoP during an organizational transition phase of three years. The longitudinal data were collected with interviews of 13 academics from the fields of science and technology. The findings reveal a variety of pedagogical development activities related to shared meanings, practices, identities, and ways of belonging. The activities are aligned with the organizational transition process and enabled by collegial support. The findings indicate that lack of supportive formal leadership may terminate the informal development activities. The resulting model of change agency provides a novel approach to pedagogical development in higher education.     

Online peer observation: its value in teacher professional development,support and well-being

This article discusses an online peer observation project conceived to enhance language-teacher positivity and creativity in synchronous virtual classrooms. Participants worked part-time at the UK’s Open University (OU) in a blended context and came from two different groups distant from each other and geographically dispersed within their own group. As a result of the project, participants perceived an increase in their confidence and greater willingness to experiment. They appreciated better how they fitted into the wider OU teaching community, built new professional friendships and flexible communities of practice, and developed a better understanding of how to progress their own self-development.     

Synchronic Tutoring of a Virtual Community

The role of tutors has changed over time, depending on models of learning and on the technology available. This article discusses the evolution of the tutor role and presents a new model concerning the tutoring functions in a synchronous virtual community. The definition of a virtual community starts from a theory of communities of learning and takes the features of the virtual environment into account. A project set in order to verify the tutors' features in a synchronous virtual community with an educational aim will be described in detail. The chats on-line are analyzed combining two analysis systems: (a) a category system describing the tutor's on-line functions; and (b) a discourse analysis exploring the dialogical and interactive dimensions of the tutor interventions. Results gathered from this study highlight typical features of tutoring on-line a virtual community. On-line tutorship appears to be a fluid, situated and dynamic process of meaning negotiation. Tutors are able to take over each others' specific roles and students act as tutors to each other.     

The Panther

His vision, from the constantly passing bars,
Has grown so weary that it cannot hold anything else
It seems to him there are a thousand bars;
and behind the bars, no world.     

Modeling information sources as integrals for effective and efficient source selection

In this paper, a new source selection algorithm for uncooperative distributed information retrieval environments is presented. The algorithm functions by modeling each information source as an integral, using the relevance score and the intra-collection position of its sampled documents in reference to a centralized sample index and selects the collections that cover the largest area in the rank-relevance space. Based on the above novel metric, the algorithm explicitly focuses on addressing the two goals of source selection; high-recall, which is important for source recommendation applications and high-precision which is important for distributed information retrieval, aiming to produce a high-precision final merged list.     

Beauty,effort and talent: a brief history of Brazilian women’s soccer in press discourse

This essay offers a brief historical background to the evolution of women’s soccer in Brazil. It focuses on the main obstacles women faced to pursue the game, which was forbidden to women in Brazil in 1941. By analysing how the newspapers treat women’s teams, the essay will try to highlight significant changes in the stereotypes that long guided perceptions of people about women soccer players.

Criss-cross heart three-dimensional printed models in medical education: A multicenter study on their value as a supporting tool to conventional imaging

The utility of three-dimensional (3D) printed models for medical education in complex congenital heart disease (CHD) is sparse and limited. The purpose of this study was to evaluate the utility of 3D printed models for medical education in criss-cross hearts covering a wide range of participants with different levels of knowledge and experience, from medical students, clinical fellows up to senior medical personnel. Study participants were enrolled from four dedicated imaging workshops developed between 2016 and 2019. The study design was a non-randomized cross-over study to evaluate 127 participants' level of understanding of the criss-cross heart anatomy. This was evaluated using the scores obtained following teaching with conventional images (echocardiography and magnetic resonance imaging) versus a 3D printed model learning approach. A significant improvement in anatomical knowledge of criss-cross heart anatomy was observed when comparing conventional imaging test scores to 3D printed model tests [76.9% (61.5%–87.8%) vs. 84.6% (76.9%–96.2%), P < 0.001]. The increase in the questionnaire marks was statistically significant across all academic groups (consultants in pediatric cardiology, fellows in pediatric cardiology, and medical students). Ninety-four percent (120) and 95.2% (121) of the participants agreed or strongly agreed, respectively, that 3D models helped them to better understand the medical images. Participants scored their overall satisfaction with the 3D printed models as 9.1 out of 10 points. In complex CHD such as criss-cross hearts, 3D printed replicas improve the understanding of cardiovascular anatomy. They enhanced the teaching experience especially when approaching medical students.
