Pedro Gutiérrez Bueno wrote two editions of a chemistry textbook between 1788 and 1802. The paper offers a comparative view
of both editions taking into account Gutiérrez Bueno’s biography, his intended audience and the changes related to the so-called
chemical revolution. Some conclusions are at odds with common images about scientific revolutions and the role of textbooks
in science. The analysis aims to shed some light on the multiple historical forces shaping textbooks and the way in which
scientific change is assimilated by their writers.

The aim of the present study is to elicit students’ understanding of the particulate nature of matter via a cross-age study
ranging from secondary to tertiary educational levels. A questionnaire with five-item open-ended questions was administered
to 166 students from the secondary to tertiary levels of education. In light of the findings, it can be deduced that the number
of students’ responses categorized under the “sound understanding” category for each item increased with educational level,
except for U1. Also, it can be concluded that students’ specific misconceptions decreased steadily from SHS1 to SHS3, except
for item 4, but there is surprisingly a clear increase at U1. 相似文献

县级中学高中生物理考试成败归因特点 总被引:1,自引:0,他引:1
以435名县级中学高中生为被试,以考试成败归因问卷为工具,旨在探讨高中生对物理考试成败结果的归因特点。研究表明:(1)整体上看,县级中学高中生对物理考试成败倾向于作内部归因,他们将持久努力、临时努力和学习方法等内部可控原因视为首要原因;(2)自我评价成功者与失败者对考试结果的归因存在明显差异;(3)男女生对考试成功的归因不存在明显的差异,对考试失败的归因有一定差异,女生比男生更看重能力、学习方法、学习基础与任务难度等原因对失败结果的影响;(4)高中生对考试成败的归因不存在明显的年级差异。 相似文献

First‐generation undergraduate students face challenging cross‐socioeconomic cultural transitions into college life. The authors compared first‐ and non‐first‐generation undergraduate students’ social support, posttraumatic stress, depression symptoms, and life satisfaction. First‐generation participants reported less social support from family and friends, more single‐event traumatic stress, less life satisfaction, and marginally more depression symptomatology than non‐first‐generation participants, but significant generation–gender interactions showed first‐generation women doing worse and first‐generation men doing better than others. 相似文献

Working memory and planning are fundamental cognitive skills supporting fluid reasoning. We show that 2 games that train working memory and planning skills in school‐aged children promote transfer to 2 different tasks: an attentional test and a fluid reasoning test. We also show long‐term improvement of planning and memory capacities in 8‐year‐old children after playing adaptive computer games specifically tailored to entrain these cognitive functions. Working memory capacity expanded from 5 to 7 items by using our games. Furthermore, steady progression in the task indicates that this capacity can be trained rapidly. Planning abilities persisted in a nonmarkovian form of play, where a move is highly influenced by previous moves, avoiding back‐ups. Here, we introduce a public and growing platform ( http://www.matemarote.com.ar/ ) developed for this research which has the potential for wide use in educational research. 相似文献

In 2011 we, a group of English-as-a-foreign-language teachers at a secondary school in Argentina, decided to investigate our teaching practices through collaborative action research so as to improve our students’ learning opportunities and thus revitalise English-language teaching in our context. We implemented and evaluated the integration of content and language learning in our classrooms through the development of our own materials. The experience revealed a growth in professional development and how our motivation and autonomy influenced our students’ motivation and language development. In our attempt to disseminate our experience as a group, this report particularly focuses on the evaluation facets of our collaborative action research project so as to encourage other teachers and teacher-researchers to adopt collaborative action research to improve their own practices. 相似文献

The aim of this research is to identify the difficulties experienced by secondary school students (aged 15–16) with the critical reading of newspaper articles with scientific content. Two newspaper critical reading activities in relation to the study of various scientific contents were designed and carried out in two schools (61 students in total), one with a student population from a medium to high social and economic bracket and the other with students from a medium to low social and economic bracket. These activities were designed taking into account the phases of the reading process: before, during and after reading. In order to analyse the difficulties ‘Elements of science critical reading’ were identified on the basis of the ‘Elements of reasoning’ of Paul and Elder and the categories proposed by Bartz C.R.I.T.I.C. questionnaire and a scale was drawn up. The results show that the activities designed were useful in helping students to read critically. We also rated very positively the instrument created to assess the students' answers: the scale based on the performance indicators of Paul and Elder. This instrument enabled us to detect the aspects of critical thinking where students have the most difficulties: identifying the writer's purpose and looking for evidence in a text. It was also shown that the stance taken in the articles also had an influence on the results. 相似文献

Abstract Within education, some teachers’ interpretation of professionalism emphasizes conformity to the perceived norms of collective associations. Unprofessional behaviour, often equated with ‘unethical’ behaviour, is seen by many to be that which threatens solidarity and loyalty to colleagues. Informal norms typified by casual collegial relations as well as more formal attachments to organized unions or teachers’ federations exert a significant influence on individuals’ behaviour within the group. Professional ethics, in this sense, become concerned primarily with how one relates to colleagues rather than how one fulfils moral responsibilities to students. Qualitative findings from interviews with elementary and secondary school teachers suggest that, as a result of an ethic of collegial loyalty, some teachers experience personal moral and ethical dilemmas that they find difficult to resolve. Some respondents acknowledged that this can enable serious situations to be ignored or ‘covered up’. This paper examines some of the tensions and dilemmas experienced by teachers and raises questions about the ethical adequacy of defining professionalism in terms of inter‐colleague behaviour. 相似文献

This article presents our experience of testing the OpenSim platform as a tool in teaching French to 108 tourism students at Universidad Rey Juan Carlos (Madrid, Spain). The article begins with some theoretical reflections on the behaviour of the student when using a virtual platform by means of an avatar, and with our observations of how this doubling of identity is actually the greatest asset of virtual worlds when we intend to apply them to teaching (1. Introduction). Then we move on to present our goals and method of work (2. Aims and methodology) and to analyse the development of the virtual space or sim, setting out the teaching strategies that were employed in each of the islands we created, and which correspond to reading comprehension, listening comprehension and written expression (3. Metaverse design). In order to assess the language learning results, we also devised tests throughout the experiment, which were repeated one month later. The assessment shows that the process of language acquisition is positive (4. Results analysis). Finally, we demonstrate that the rise of virtual worlds has been backed up by psycholinguistic factors, but at the same time their applicability and sustainability depend on technical aspects and very especially on theoretical and pedagogical tenets which are still to be drawn up (5. Conclusions). 相似文献

Over the last few years, information and communication technologies have become an essential part of daily life, affecting education, employment, and leisure, among other activities. Nonetheless, many individuals still reap few or no benefits from these technologies, and there are resilient gaps in their use. Within this larger context, the authors examine the Internet digital divide between people with and without disabilities from a multidimensional approach. Rather than analyzing the gap in terms of “haves” and “have-nots,” a range of Internet-related dimensions—affordability, motivation and attitudes, skills, usage, and others—is taken into account. 相似文献
