Knowledge and Attitudes Towards Biotechnology of Elementary Education Preservice Teachers: The first Spanish experience     

Marina Casanoves  Ángel González  Zoel Salvadó  Juan Haro 《International Journal of Science Education》2013,35(17):2923-2941

Due to the important impact that biotechnology has on current Western societies, well-informed critical citizens are needed. People prepared to make conscious decisions about aspects of biotechnology that relate to their own lives. Teachers play a central role in all education systems. Thus, the biotechnological literacy of preservice teachers is an important consideration as they will become an influential collective as future teachers of the next generation of children. The attitudes toward science (and biotechnology) that teachers have affect their behavior and influence the way they implement their daily practice of science teaching in school. This study analyzes the attitudes and knowledge of Spanish preservice teachers toward biotechnology. We designed a new survey instrument that was completed by 407 university students who were taking official degree programs in preschool and primary education. Our results point out that although they are aware of biotechnology applications, topics concerning the structure of DNA, management of genetic information inside the cell, genetically modified organism technology and the use of microorganisms as biotechnological tools were not correctly answered. According to our attitude analysis, Spanish preservice teachers could be defined as opponents of genetically modified product acquisition, supporters of biotechnology for medical purposes and highly interested in increasing their knowledge about biotechnology and other scientific advances. Our results show a positive correlation between better knowledge and more positive attitudes toward biotechnology. A Spanish preservice teacher with positive attitudes toward biotechnology tends to be a student with a strong biology background who scored good marks in our knowledge test.  相似文献

The transformative power of Chicana/o Studies: social justice and education     

Aída Hurtado 《International journal of qualitative studies in education》2013,26(2):185-197

This essay responds to Professor Aguirre’s article in this issue that explores through personal narrative the trials and tribulations of being a faculty member with an expertise in Chicana/o Studies. The author joins his exploration by introducing the structural disadvantages that Chicana/o Studies suffers as a field. She then expounds on what we have gained by developing a new field with an explicitly political focus that includes putting student interests at the center of its development while fighting for economic and social justice as an integral part of its intellectual agenda. Her conclusion explores the challenges that the field of Chicana/o Studies faces as we confront changing demographic and societal conditions.  相似文献   

Mexican parents’ and teachers’ literacy perspectives and practices: construction of cultural capital     

Leslie Reese  Rebeca Mejía Arauz  Antonio Ray Bazán 《International journal of qualitative studies in education》2013,26(8):983-1003

This article examines the relationships among the literacy practices engaged in by first-grade children and parents at home and the ways in which these practices are communicated, shaped, and fostered by teachers and administrators in two different sociocultural environments in urban Mexico. The differences observed between the home literacy experiences of children in a working-class and a middle-class community included transgenerational communication of assumptions regarding literacy and schooling, as well as attitudes associated with the parents’ own school experiences. Class-based expectations on the part of teachers not only shaped interactions with parents, but were also reflected in the way the national curriculum was delivered, with a greater emphasis on rote skills and traditional reading instruction in the working-class community. The authors argue that the school plays a role in the co-production of cultural capital in the home through its shaping of some of the literacy practices that children and families undertake.  相似文献   

Visualising learning design to foster and support good practice and creativity     

Gráinne Conole  Andrew Brasher  Simon Cross  Martin Weller  Paul Clark  Juliette Culver 《Educational Media International》2013,50(3):177-194

Applying Bandura's social learning theory, this paper proposes a theoretical framework for analysing the effect of MUD playing on users' self efficacy. Three types of self efficacy – computer self efficacy (CSE), social self efficacy (SSE) and generalized self efficacy (GSE) – are introduced. A possible hypothesis – successful performance, vicarious experience, hearing positive verbal persuasion and massive exposure during MUD playing will raise the CSE, SSE, and GSE of users – is suggested. Finally, a theoretical model explaining the relationship between self efficacy and MUD activities is proposed.

Applicant la théorie de l'apprentissage de Bandura cet article propose un cadre théorique pour analyser les effets de MUD jouant sur l'efficacité personnelle de l'utilisateur. 3 types de celles-ci - computer self-efficiency (CSE) social self efficacy (SSE) et generalisé self-efficiency (GSE) - sont introduits et une hypothèse possible. Les résultats réussis, expérience substituée, écoute de la persuasion verbalement et l'exposition massive au jeu de MUD augmentera le CSE, SSE et GSE des utilisateurs est suggéreé. Finalement un modèle théoritique expliquant le rapport entre l'efficacité personnelle et les activités de MUD est proposé. NDLR.

(MUD: multi-user domain, multi-user dungeon, oder multi-user dimension; eine (virtuelle) Umgebung, in der mehrere Menschen (Spieler) gleichzeitig eingeloggt sein können, um miteinander zu agieren (Rollenspiele).?/?Efficacy: wörtl.: Wirksamkeit - Der Übersetzer). Unter Anwendung von Banduras Sozialer Lerntheorie wird in diesem Beitrag ein theoretischer Rahmen vorgestellt, mit dessen Hilfe man die Wirkung des MUD-Spielens auf das Selbstvertrauen der Teilnehmer analysieren kann. Es werden drei Arten dieses Selbstvertrauens eingeführt - Computer self efficacy (CSE), Social self efficacy (SSE) und Generalized self Efficacy (GSE). Die Hypothese ist, dass durch die erfolgreiche Durchführung Ersatzerfahrungen, das Hören positiver verbaler Bestätigung und das massives Ausgeliefertsein während des MUD-Spielens das Selbstbewußtsein (CSE, SSE und GSE) des Spielers erhöht wird. Zum Schluss wird ein theoretisches Modell zur Beziehung zwischen Selbstvertrauen und MUD-Aktivitäten vorgestellt.  相似文献

Some factors associated with reading ability: a longitudinal study     

Sheila M. Williams  Phil A. Silva 《Educational research; a review for teachers and all concerned with progress in education》2013,55(3):159-168

The paper reports a longitudinal study of factors associated with reading ability in a large sample (N=748) of children. Reading was assessed when the children were aged seven and later at age nine. The associated measures included measures of background, experiences and earlier cognitive development. It was found that the correlation between reading at age seven and reading at age nine was 0.87. However, reading at seven and nine were both associated with the background measures and to a lesser extent with experiential measures. Reading at seven was associated with earlier cognitive development. The implications of the results are discussed.  相似文献   

Measuring the local economic impact of universities: an approach that considers uncertainty     

José Manuel Pastor  Francisco Pérez  Juan Fernández de Guevara 《Higher Education》2013,65(5):539-564

The contribution of universities to society is due to the effects generated both in the supply and in the demand side, the latter being associated with the injection of demand as a result of the activities these institutions carry out. This paper focuses on the impact of the demand side by designing a methodology based on Monte Carlo simulations so as to introduce stochastic elements in calculating the economic impact of universities. We apply this methodology to the case of Valencian public universities, introducing stochastic elements in all the elements which imply assumptions with uncertainty. The results highlight the importance of considering uncertainty by generating multipliers which can vary around the average value by 18 % in the case of output and employment, and 10 % in the case of income.  相似文献   

Cultivating Human Capabilities in Venturesome Learning Environments     

Pádraig Hogan 《Educational theory》2013,63(3):237-252

The notion of competencies has been a familiar feature of educational reform policies for decades. In this essay, Pádraig Hogan begins by highlighting the contrasting notion of capabilities, pioneered by the research of Amartya Sen and Martha Nussbaum. An educational variant of the notion of capabilities then becomes the basis for exploring venturesome environments of learning: environments that are hospitable to the cultivation of such capabilities among students and their teachers. In this exploration Hogan emphasizes disclosing the kinds of relations that constitute such environments. In particular, he identifies four kinds of relations and investigates the interplay among them. In the second part of the essay, Hogan reviews an ongoing research project in Ireland that has been promoting such environments in postprimary education: Teaching and Learning for the 21st Century. Although the project avoids proffering universal claims about “what works,” its rationale and conduct nevertheless call policymakers' attention to what has worked and to the reasons why.  相似文献   

An analytical framework for analyzing student teachers’ verbal interaction in learning situations     

Victoria Sánchez  Mercedes García  Isabel Escudero 《Instructional Science》2013,41(2):247-269

This paper focuses on the study of student teachers’ verbal interaction in learning situations generated in a classroom corresponding to a mathematics methods course. In our work, we incorporate two ‘ways of seeing’ a group: as an entity or as a set composed of individualities. We present an analytical framework that considers two dimensions connected with these ways of seeing the group and four variables corresponding to these dimensions, through which the verbal interaction between student teachers in a group can be considered. As regards the first dimension, the variables included are specific language, cognitive processing, social processing; the second dimension considers the relational variable. We describe each of the different variables that form the framework, and how this framework allows us to analyse the verbal interaction in three groups of student teachers. We believe that building analytic frameworks that allow the study of verbal interaction in detail is worthwhile in the educational field due to their important role in the analysis of learning-teaching processes.  相似文献
