The rapid growth of biotechnology knowledge during the past decades has made it necessary to rethink the contents of the school curriculum and has provoked a consideration of the ethical and social issues related to the use of biotechnological applications. With the financial assistance of the European Union, the European Initiative for Biotechnology Education was set up to develop units for use in the member the countries, organize the translations of these between the many languages involved, organize in‐service courses for teachers, implement the materials in schools, as well as carrying out related research.

This paper gives some findings of Spanish researchers when identifying and exploring the different cultural contexts in which biotechnology teaching and learning is embedded, being mainly concerned with the emerging attitudes and values of the students regarding such issues. After gathering information through case studies during the implementation phase, a questionnaire was developed in an interactive way by teachers and researchers in various stages, based on what students said.

The results identify four main values: the “principle of the natural”, the “principle of the welfare”, the “principle of the technological solution” and the “principle of the individual decisions”. Their interaction and dichotomy are discussed, as well as the problems teachers face when having to deal with topics beyond those immediately related to science  相似文献

In this article the authors resort to a qualitative analysis of the plot of science fiction stories about a group of scientists, written by two 11th‐grade Earth and Life Science students (aged 17), and to semi‐structured interviews, with the double purpose of diagnosing their conceptions of the nature of science (namely, as regards scientists’ activity), and discussing the potentialities of this methodology in terms of research and education in science. The adopted methodology proved particularly effective in diagnosing the students’ conceptions of scientists’ characteristics, scientific activity, and science–technology–society interactions. The limited content of certain conceptions and a certain lack of knowledge on the part of the students concerning the processes and the epistemology of science highlight the need to pay explicit attention in science classes to the nature of scientific activity. Some of the ideas brought up by the students clearly show the influence of stereotypes and catastrophic scenarios depicted in films, television programs, and books, revealing media’s limitations when divulging scientific and technological themes to the general public and stressing the need for the school to promote a critical debate about science and technology images conveyed by the media.  相似文献

Student teachers were tested before and after a teaching unit on electrostatic interactions in an attempt to consider their intuitive ideas and concept development. A study was made of students’ explanations of basic interactions: those between two charged bodies, and those between a charged body and a neutral body. Two indicators of the cognitive status of the explanations were investigated: “context dependence” and “certainty or confidence index”. This allowed cognitive comparisons to be established between the explanations of different electrostatic interactions, and between the degrees of difficulty they represent for satisfactory conceptual evolution. The greatest difficulties were found with explanations of the phenomena of electrostatic induction. The sample consisted of 52 students in primary school teacher education who participated in a teaching unit designed to overcome these obstacles.  相似文献

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

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

CADMOS is a graphical learning design (LD) authoring tool that helps a teacher design a unit of learning in two layers: (i) the conceptual layer, which seems like a concept map and contains the learning activities with their associated learning resources and (ii) the flow layer, which contains the orchestration of these activities. One of CADMOS’ main innovative features is that it can bridge the gap between the design of a unit of learning and its enactment into Moodle. This paper presents how one can create a LD using CADMOS and deploy it into Moodle. Also, the paper shows the findings from a case study which was organized in order to evaluate the usability of the tool, its pedagogical flexibility and the usefulness of its innovative feature of deploying a LD into Moodle. CADMOS seems to be an easy-to-use tool, which offers guidance and flexibility during the design process.  相似文献

College-bound recipients of DACA—a 2012?US administrative policy officially titled Consideration for Deferred Action for Childhood Arrivals—face a series of administrative and financial barriers in pursuing postsecondary education. These barriers often include a complicated process for in-state tuition consideration, as well as exclusion from the majority of educational subsidies. This research sheds new light on DACA students’ own understanding of their financial exclusions and the often ingenious methods they use to finance higher education. The research employs critical race theory/LatCrit frameworks to examine the structural systems of exclusion within educational policies and the corresponding measures taken by DACA recipient students in Ohio to overcome them. Participants’ testimonios highlight their own resilience in the face of multiple obstacles, dispel notions of meritocracy in higher education, and educate institutional agents about funding inequities in an effort to rectify them. This work finds, in response to the barriers they face, many DACA recipients in Ohio find a variety of unconventional ways to navigate a complex admissions process and secure a means of paying entirely out of pocket for their tuition. Participants in this longitudinal, qualitative research refer to these navigational strategies as participating in “the scheme game.” The scheme game consists of 3 overlapping practices: “grindin’,” “hustlin’,” and “schemin’.” Rooted in hip-hop, these terms originally refer to the ways Black, Brown, and immigrant communities navigate the barriers of a formal economy and participate in an informal economy to financially sustain themselves. Additionally, the research introduces the scheme game as a new epistemological perspective from which to understand the measures some DACA students take to afford a higher education.  相似文献

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

Understanding how children experience life in educational settings should be an imperative for educational practitioners, evaluators, and researchers. Listening to children’s points of views would facilitate the development of educational settings that meet the needs of children and contribute to their wellbeing and development so that their experiences are both joyful and meaningful. A total of 56 children between the ages of 5 and 7 in 65 educational settings located in central Sweden were included in the study. Amongst the 56 participating children, 29 were identified as having special educational needs. The children’s views were collected from 2012 to 2015 using drawings and interviews, and these were analysed using a thematic analysis. Nine themes that reflected matters of importance for the children, both those with and without special educational needs, are described. These themes are discussed and linked to previous research, educational evaluation models, and theories of values and needs.  相似文献
