Comprehensiveness in child healthcare teaching in Undergraduate Nursing: perspective of teachers

This qualitative study analyzed, from the teacher’s perspective, if the principle of comprehensiveness is included in child healthcare teaching in nursing education. The participants were 16 teachers involved in teaching child healthcare in eight undergraduate nursing programs. Data collection was performed through interviews that were submitted to thematic content analysis. The theory in teaching incorporates comprehensive care, as it is based on children’s epidemiological profile, child healthcare policies and programs, and included interventions for the promotion/prevention/rehabilitation in primary health care, hospitals, daycare centers and preschools. The comprehensive conception of health-disease process allows for understanding the child within his/her family and community. However, a contradiction exists between what is proposed and what is practiced, because the teaching is fragmented, without any integration among disciplines, with theory dissociated from practice, and isolated practical teaching that compromises the incorporation of the principle of comprehensiveness in child healthcare teaching.

Quimiluminescência orgânica: alguns experimentos de demonstração para a sala de aula

The generation of "cold light", visible to the human eye, by chemical reactions has attracted the attention of the scientific community since the beginning of this century. Besides the academic interest in the elucidation of the mechanisms of excited state formations, many chemiluminescence reactions have found widespread analytical applications. Moreover, the phenomenon of chemiluminescence can also be used as a tool in undergraduate and college teaching. In this article, we describe several known chemiluminescence demonstrations, which are suitable for school teaching. The main objective of this work is to produce didactic material in Portuguese to stimulate Brazilian secondary and high school teachers to use these experiments in the classroom. The demonstrations include singlet oxygen emission, the luminol reaction, oscillating chemiluminescence and the peroxyoxalate reaction.

Química orgânica experimental: integração de teoria, experimento e análise

A new approach for teaching in basic experimental organic chemistry is presented. Experimental work goes on parallel to theoretical lectures leading to an immediate application of theoretical concepts transmitted therein. One day/week is dedicated exclusively to the organic laboratory. Reactions are proposed as problems to be solved; the student has to deduce the structure of the product on the basis of his observations, the analytical data and his mechanistical knowledge. 70 different experiments, divided in 7 thematical chapters, are presented. All experiments require the analysis and discussion of 1H and 13C NMR, IR and UV spectra. Additional questions about each reaction have to be answered by the student in his written report. Laboratory safety is garanteed by the exclusion or substitution of hazardous and toxic reagents. Microscale preparations are adopted in most cases to lower the cost of materials and the amount of waste. Recycling of many reaction products as starting materials in other experiments reduces the need for commercial reagents and allows the execution of longer reaction sequences. Only unexpensive standard laboratory equipment and simple glassware are required. All experiments include instructions for the save treatment or disposal of chemical waste.

Aplicação de extratos brutos de flores de quaresmeira e azaléia e da casca de feijão preto em volumetria ácido-base. Um experimento para cursos de análise quantitativa

Crude extract of Tibouchina granulosa, Rhododendron simsii and Phaseolus vulgaris L. were prepared and used as alternative indicators in quantitative analysis teaching in standardization of NaOH solutions and in the determination of acetic acid contents in vinegar. Effect of using such natural extracts as indicators was very attractive to the students and the quantitative results were compared with conventional indicators with good agreement. Concepts of data statistics can successfully be discussed using the interest revived by the use of natural indicators.

Eixos mobilizadores em química

Over the last five years there have been significant changes in higher education in Brazil as well as in research funding. As a contribution to the development of Science and Technology, and aiming to portray Chemistry today in Brazil, in the context of last year´s elections for President, State Governors, National Congress and Legislative Chamber, the Directors and Consulting Council of the Brazilian Chemical Society, SBQ, initiated in 2002 a series of activities to produce a document entitled Mobilizing Axes in Chemistry. This discusses undergraduate and graduate teaching in Chemistry, a new model for research funding, and the overall state of the art, and future perspectives. Six mobilizing axes have been identified and discussed to date: 1. Training of highly qualified personnel; 2. Decentralization, and discouragement of institutional in-breeding; 3. Stimulation of entrepreneurship and interdisciplinarity; 4. A guaranteed budget for Science and Technology; 5. Proactive interaction of academics with economic activity; and 6. Removal of institutional bottle-necks of all sorts. The Brazilian Chemical Society hopes that the new administration will in the near future begin the task of improving the national education system and increase funding for Science and Technology.

A formação do pós-graduando em química para a docência em nível superior

The article presents a brief analysis on chemistry post-graduate students' perception on teaching in higher education. This study was done based on the context of students' formation in chemistry post-graduate programs and makes suggestions on how to improve the formation process of post-graduate students in order to decrease the rupture between teaching and research in chemistry post-graduate programs.

Concepções e ações de formadores de professores de química sobre o estágio supervisionado: propostas brasileiras e portuguesas

The purpose of this paper is to investigate lecturers'actions and conceptions about pre-service teaching practices in chemistry. In this sense, it takes into account several theoretical references concerned with teacher education, which support the qualitative analysis of 18 interviews, gathered with 14 brazilian and 4 portuguese lecturers. Results reveal that the pre-service teaching practices in chemistry have been performed far from a technical approach, showing a paradigmatic rupture and presenting another logic related with teacher education in chemistry, which have improved the comprehension of the teachers' real practices, since these have been shaped by complex and unprescribed factors.

Jogos de empresa: aplicação à gestão da qualidade no ensino superior de química

Business games have become a popular choice of pedagogical technique for teaching in higher education. The objective of a business game is to offer students the opportunity to learn by doing, engaging them in a simulated experience of the real-world. This paper discusses how a business game has been played by undergraduate chemistry students in a Quality Management course. The responses from the teaching evaluation questionnaires revealed that they not only improved their quality management practices, but also enjoyed working in teams. The level of participation by students was good and the classroom activities provided a meaningful learning experience.

COMUNICAÇÃO CIENTÍFICA NO ENSINO SUPERIOR DE QUÍMICA: UMA REVISÃO

The importance of teaching scientific communication skills in undergraduate chemistry courses is well recognized. This paper provides an overview of didactic activities in which students engage to improve these skills. The study was based on an extensive literature review performed on the Journal of Chemical Education and on the Journal of College Science Teaching, in the years spanning from 1991 to 2010, and on The Chemical Educator, from 1996 to 2010. The findings from the study provided an opportunity to expand the knowledge on the variety of methods and contents used to teach scientific communication skills in undergraduate chemistry education, as well as to deepen our understanding of the effects of different approaches to teaching on performance in practice.
