Objective: To analyze the association between attitudes of filial responsibility and adult child caregivers’ behaviors in the Southern Region of Brazil.

Methods: Cross-sectional study with 100 child caregivers of older adults. The data were collected through an interview using the protocol of filial responsibility adapted and validated to Brazilian Portuguese. Filial Expectation and Filial Piety scales evaluated the attitudes of filial responsibility. Caring behaviors assessed were: instrumental support, emotional, financial support, and companionship. The variables that presented p< .20 value in the bivariate analysis were inserted into a multivariate Poisson regression model.

Results: Financial and emotional support behaviors were significantly associated with filial piety (p = .050 and p = .001, respectively) and filial expectation (p = .013 and p = .023, respectively). Providing companionship was associated with filial piety (p = .015).

Conclusion: Attitudes of filial responsibility are associated with some but not all caregiving behaviors. Brazilians caring for older parents show more similarities to Chinese than to Canadian caregivers. Furthermore, filial responsibility and caregiving behaviors are strongly affected by Brazilian social and cultural norms. Reasons are discussed.  相似文献

There is, broadly speaking, an agreement within the international science education community that comprehension of the nature of science (NOS) should be a key element in the scientific literacy of citizens. During the last few decades, several didactic approaches have emerged concerning what and how to teach NOS. Also, one of the basic objectives of science education is for students to become familiar with the skills typical of scientific practice; however, there is little reference to their need to also acquire meta-knowledge about scientific practice (i.e., an understanding of the nature of scientific practice). Among other reasons, this may be due to NOS being essentially identified in most of the predominant proposals with the nature of scientific knowledge. But why not plan the teaching of science to be in tune with real scientific practice for students to learn about the nature of scientific practice at the same time as they are learning science? The answer to this question has given rise to a proposal grounded in ten essential pedagogical principles for the teaching and learning of science in secondary school. These are the principle of formulating questions, the principle of creativity and imagination, the principle of experimentation, the principle of procedural diversity, the principle of errors as opportunity, the principle of modeling, the principle of cooperation and teamwork, the principle of argumentation and discussion, the principle of communication, and the principle of evaluation. The purpose of this article is to present the justification and fundaments of these principles.  相似文献

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. This research was partially supported by the program BHA2002-04611-CO3-02  相似文献

We proposed in the Basic Microbiology Subject for food science and nutrition students, a “hands‐on” activity consisting on sampling student's hands for bacterial presence and identification. This is a project to be implemented in multiple laboratory classes throughout the semester, allowing students to learn, and apply general microbiology techniques in mixed or isolated cultures obtained from their own samples in parallel with those from the laboratory collection proposed in the microbiology syllabus (as aseptic technique, hands sampling, streaking for single‐colony isolation, culture medium analysis, bacterial morphology, and biochemical study, employ of dichotomous keys) This activity will allow them to understand the association between humans and microorganisms, to recognize the importance of personal hygiene (for example, hand‐washing), and to know how hands can be an important vehicle for bacterial spreading in surrounding environments (for example, kitchen, health‐care setting). The fact that the isolates for practical work were not only from laboratory collections, but also from the personal student's hands, keeps them interested in discover and study their own bacteria to know their main characteristics and the potential importance to human health, through spread of hazardous isolates. This project also potentially contributed for student's development of other skills such as autonomy and teamwork, planning and write, communication, and debate.  相似文献

In this work, we presented an analysis of the representation of the special relativity theory (SRT) in the most used texts in high school, Polimodal level and university level in the teaching in the Argentine Republic, from a historic, epistemological and didactic perspective. The results show that none of the analyzed texts would allow a contextualized approach on such theory.  相似文献

This paper gives background information on early childhood services in Ireland and presents the results of a survey of the preschool experiences of 1065 children. The results of the survey suggest that the majority of children experienced some form of early childhood service before starting school. The most common service was a playgroup although a significant proportion of the children had experienced home‐based care with a relative or family day care provider. The implications of the findings for the development of a policy on early childhood services are discussed.  相似文献

The AGIRE project, under the Edulab concept, aims to promote the adoption of innovative teaching practices. This paper reports the support strategies used to evaluate the teacher practices at the end of a teacher training course (TTC) and analyse its impact on teacher technology integration, using a design-based methodology. Teachers’ initial perception was gathered using an online questionnaire comprising ICT personal and professional competencies. The questionnaire results and the classroom observations showed that the majority of teachers were at the level of ICT adoption, before attending the TTC, reaching the adaptation level of integration of ICT, after the TTC. A variety of teaching strategies (flipped classroom, collaborative work, …) and technologies (interactive white boards, tablets, videos, …) were explored. The results sustain the thesis that, with proper support, ICT can be integrated in educational contexts in an innovative way and contribute to the development of teachers’ digital literacy.  相似文献

Despite its frequent use, there is little understanding of the concept of differential among upper high school and undergraduate students of physics. As a first step to identify the origin of this situation and to revert it, we have done a historic and epistemological study aimed at clarifying the role and the meaning of the differential in physics and at improving curricular and teaching models in the sense of Gilbert et al. (Gilbert J.K., Boulter C., & Rutherford, M.: 1998a, International Journal of Science Education 20(1), 83–97, Gilbert J.K., Boulter C., & Rutherford, M.: 1998b, International Journal of Science Education 20(2), 187–203). We describe the contributions of Leibniz and Cauchy and stress their shortcomings, which are overcome by the alternative definition proposed by the French mathematician Fréchet, dating from early 20th century. As a result of this study, we answer to some fundamental questions related to a proper understanding of the differential in physics education (for 17–19 years old students).  相似文献

This article examines how 31 triads of 6- to 10-year-old children from 3 cultural backgrounds organized their interactions while folding Origami figures. Triads of children whose families had immigrated to the United States from indigenous heritage regions of México (and whose mothers averaged only 7 grades of schooling) coordinated more often as an ensemble, whereas triads of European heritage U.S. children whose mothers had extensive schooling more often engaged dyadically or individually. When the European heritage children did engage as an ensemble, this often involved chatting rather than nonverbal conversation regarding folding, which was more common among the Mexican heritage children. Mexican heritage U.S. triads whose mothers had extensive schooling showed an intermediate pattern or resembled the European heritage children.  相似文献
