La adquisición de la interrogación: las interrogativas parciales en catalán y castellano = The acquisition of interrogatives:Wh-questions in Catalan and Spanish

En este trabajo se describe la naturaleza y secuencia de adquisición de las preguntas interrogativas parcialesen niños de habla catalana y/o castellana dentro de un marco de análisis según el cual la adquisición de lasestructuras lingüísticas se construye gradualmente desde estructuras concretas hasta estructuras más abstractas.La muestra utilizada se compone de 10 niños y niñas procedentes de corpus longitudinales cuyas edades van delos 17 meses a los 3 años. El análisis se ha realizado atendiendo a la estructura sintáctica de la oración, loserrores, los pronombres y adverbios interrogativos, y la tipología verbal. Los resultados muestran que la secuenciade adquisición pasa por un momento inicial caracterizado por producciones estereotipadas o fórmulas,durante el cual sólo aparecen algunas partículas interrogativas en estructuras muy concretas. Posteriormente lainterrogación aparece con otros pronombres y adverbios y se diversifica a otros verbos, además, no se observanerrores en la construcción sintáctica. Estos resultados suponen un hecho diferencial respecto de estudios previos enlengua inglesa

Visões de ciências de professores de química: a mídia e as reflexões no ambiente escolar no nível médio de ensino

The present paper discusses the influence of TV and general media on students scientific ideas and the teacher's perception of this influence on students during class time. 17 high-school chemistry teachers with teaching degree, working in state schools, were interviewed. The interviews showed that both, teachers and students, have a positive opinion of science and the scientist. According to their teachers, students' positive view of science is greatly influenced by TV. The developed study shows how important epistemology is in teachers' college formation to offer them a critical perception of science treated in general media.

Simulação Monte Carlo no ensino de luminescência e cinética de decaimento de estados excitados

A software based in the Monte Carlo method have been developed aiming the teaching of important cases of mechanisms found in luminescence and in excited states decay kinetics, including: multiple decays, consecutive decays and coupled systems decays. The Monte Carlo Method allows the student to easily simulate and visualize the luminescence mechanisms, focusing on the probabilities of the related steps. The software CINESTEX was written for FreeBASIC compiler; it assumes first-order kinetics and any number of excited states, where the pathways are allowed with probabilities assigned by the user.

Comparação entre um trocador aniônico de sal de amônio quaternário de quitosana e um trocador comercial na extração de fósforo disponível em solos

The present work aimed modify chemically the chitosan (QTS) surface to obtain a reticulate chitosan quaternary ammonium salt (SAQQR), and compare this anionic exchanger with an commercial ion exchanger in the extraction of available phosphorus in soils. The results showed that the two exchangers are identical, extracting similar and proportional quantities of available phosphorus in the studied soils, and the anionic exchanger of SAQQR provides a high chemical stability, not affected by the pH difference of soils.

Aspectos históricos dos cursos de licenciatura em química no Brasil nas décadas de 1930 a 1980

This article describes some historical moments in the establishment and development of chemistry teacher's training courses since 1930, with the creation of universities in Brazil, until 1980. Correlations between educational and political questions that influenced the directions taken for the formation of chemistry teachers in Brazil are discussed. From a review of the bibliographical sources available, we revisited stances of discussions on public policies related to science teacher's formation in general and in chemistry, particularly, in order to provoke a reflection on what challenges and prospects exist in the current scenario of undergraduate chemistry education in Brazilian universities and colleges.
