An analysis of visual oddity concept learning in a California sea lion (Zalophus californianus)

We tested a California sea lion for visual oddity learning by presenting problems composed of three two-dimensional black-and-white stimuli, two identical (S−) and one different (S+). In the first experimental stage, a single problem per session was presented until learning criterion was reached. In the second experimental stage, all problems were presented only five times in succession; then a new problem was introduced (six problems/session). In the third experimental stage, each problem was presented only once. The sea lion mastered all stages of oddity learning. A final transfer test with oddity problems composed of completely new stimuli yielded performance significantly above chance. Data analyses suggested learning of specific stimulus properties in the first stage, learning set formation in the second stage, but oddity conceptualization in the third stage.     

Developing as a teacher in the fields of science and technology

In universities, development as a teacher may be contradicted with developing as a researcher. Most previous studies have investigated pedagogical development merely as a result of pedagogical training and ignored the dual teacher-researcher identity. This study examines what kind of meaningful experiences are perceived to have triggered and influenced the process of developing as a teacher in the fields of science and technology. The data were gathered by interviewing 10 academics who had participated in a pedagogical training offered by a Finnish technical university between 1999 and 2009. Based on a narrative analysis utilizing dimensions of transformative learning, the results highlight the influence of the working environment and experiences, and imply that teacher development process in the fields of science and technology can be better understood in terms of becoming a teacher, rather than as a continual, conscious development process. The resulting teacher-researcher identity provides a basis for pedagogical development.     

Visualisations as a means for exploring academics’ teacher identities

Academics’ teacher identities is a relatively little explored area. This paper explores this through an analysis of drawings by academics. The data consist of 90 drawings. The participants are academics who have attended basic courses in university pedagogy. The drawings were content analysed. In the drawings, the academics expressed themselves as teachers through the teaching context and the actors, artefacts and activities of teaching and learning. By drawing attention to these elements, academics can be encouraged to reflect on their beliefs about teaching and teacher role.     

Gendered study choice: a literature review. A review of theory and research into the unequal representation of male and female students in mathematics,science, and technology

This article presents an overview of the recent literature on gendered patterns of academic choice in mathematics, science, and technology. It distinguishes in this literature micro-level, macro-level, and institutional explanations. Micro-level explanations focus primarily on psychological constructs, that is, variables at the level of the individual students. Macro-level explanations focus primarily on socioeconomic conditions and cultural understandings of gender roles. Institutional explanations focus on design characteristics of (national) education systems. After a presentation of these perspectives and of recent research progress that has been made, the authors critically discuss the lacunae that still exist in explaining cross-national variety, and provide suggestions for designing future research in this field.     

Skizze zur Historiographie der Ästhetischen Bildung

This article is focussing on a historical approach to the term of aesthetic education from three different angles: as history of ideas, biographies and images. Aesthetic education is thereby understood as performative and reflective involvement with aesthetics and the fine arts such as arts, theatre and literature etc. A first approach is defining the history of ideas as a theoretical reconstruction of aesthetic concepts and their educational relevance; this history is also discussing educational theories and their aesthetic implications. It is more or less an implicit and compensatory history because the important contexts are not visible at first sight; and the aesthetic and pedagogical theories often need a reciprocal addition. A biographical perspective is hereby concentrated on the biography of artists. Thereby the educational science of biographies are highlighting the situation of the arts and the artists, the development of becoming an artist, the progression as an artist and the artistic institutions in a educational-aesthetic nexus. Such a perspective is supplementing the history of ideas concerning cultural and socio-historical dimensions as well as institutional and biographic aspects. Finally, the history of images is focusing on the thesis that every picture also includes a programme of aesthetic education. In pictures the process of productive and reflective visualisation is expressed: paintings refer to their production and their understanding. For the method of the historical-educational iconography of aesthetic education a historicizing matrix from production aesthetics, work aesthetics and reception aesthetics is suggested. This matrix is combined with a theory of education as transformation of self-relation, of relations to other individuals and the world. The three approaches just mentioned are exemplified by Leonardo da Vinci and his famous picture “Vitruvian Man” from 1492.     

SENCOs: vanguards or in vain?

In Sweden today, special educational needs coordinators (SENCOs) are educated at universities to help resolve educational problems related to children in need of special support at three levels, that is, the organisational level, the classroom level and the individual level. Before the education of SENCOs was created in the early 1990s, special teachers were the occupational group that worked primarily on an individual level. Children's school problems were then seen as individual deficits. SENCOs can be seen as vanguards in changing an educational system from primarily focusing on an individual perspective to a broader focus on the entire learning environment. How has the occupational role of SENCOs affected schools? The overall aim of this study is to investigate possible changes within a school system when the introduction of a new occupational group, SENCOs, challenges established structures. More specifically, this paper studies how different occupational groups view where and in what ways SENCOs work and should work. Three different questionnaires are the basis of this analysis of SENCOs' present situation within the Swedish educational system. A number of interesting findings were detected in this study. For example, several occupational groups respond that SENCOs should work with individually taught special education. Meanwhile, a pattern emerges in which SENCOs seem to have partly established a new work role. However, little is known about how these changes affect children in need of special support.     

WHEN IS A SCHOOL ENVIRONMENT PERCEIVED AS SUPPORTIVE BY BEGINNING MATHEMATICS TEACHERS? EFFECTS OF LEADERSHIP, TRUST, AUTONOMY AND APPRAISAL ON TEACHING QUALITY

This study examines the hypothesis that the more support beginning mathematics teachers perceive and the better they evaluate the management of their school, the higher their teaching quality is. Indicators of teaching quality were how the teachers, who were in their third year in the profession, regarded themselves able to cope with the challenges of mathematics instruction and generic tasks like classroom management and how satisfied they were with their job. Indicators of support were the level of appraisal and autonomy the teachers reported. School management indicators were the administrative leadership of the principal and the climate of trust as perceived by the teachers. Our results reveal that teacher support plays an important role in the quality of beginning mathematics teachers. All quality indicators improved significantly if beginning teachers reported more appraisal and autonomy. A climate of trust plays an important role for the extent of autonomy perceived. Administrative leadership was significantly related to the amount of appraisal the teachers reported. Our results provide important information on how to steer a school so that the quality of beginning mathematics teachers is maximized.     

ASSESSING STRENGTHS AND WEAKNESSES OF TEACHER KNOWLEDGE IN ASIA, EASTERN EUROPE, AND WESTERN COUNTRIES: DIFFERENTIAL ITEM FUNCTIONING IN TEDS-M

The “Teacher Education and Development Study in Mathematics” assessed the knowledge of primary and lower-secondary teachers at the end of their training. The large-scale assessment represented the common denominator of what constitutes mathematics content knowledge and mathematics pedagogical content knowledge in the 16 participating countries. The country means provided information on the overall teacher performance in these 2 areas. By detecting and explaining differential item functioning (DIF), this paper goes beyond the country means and investigates item-by-item strengths and weaknesses of future teachers. We hypothesized that due to differences in the cultural context, teachers from different countries responded differently to subgroups of test items with certain item characteristics. Content domains, cognitive demands (including item difficulty), and item format represented, in fact, such characteristics: They significantly explained variance in DIF. Country pairs showed similar patterns in the relationship of DIF to the item characteristics. Future teachers from Taiwan and Singapore were particularly strong on mathematics content and constructed-response items. Future teachers from Russia and Poland were particularly strong on items requiring non-standard mathematical operations. The USA and Norway did particularly well on mathematics pedagogical content and data items. Thus, conditional on the countries’ mean performance, the knowledge profiles of the future teachers matched the respective national debates. This result points to the influences of the cultural context on mathematics teacher knowledge.
