Estudio comparativo entre los resultados de una actividad didáctica sobre normas de correcta fabricación en formato multimedia y en formato papel

Se desarrolló una actividad didáctica (Te’n recordes de les NCF?, eminentemente práctica, en dos formatos, multimedia y papel) para reafirmar y evaluar los conocimientos sobre Normas de Correcta Fabricación (NCF) de los alumnos de la asignatura Farmàcia Galènica III.Se describe el estudio llevado a cabo para estudiar si existían diferencias significativas en los resultados obtenidos por los alumnos debidas al empleo de un material interactivo (aplicación para el ordenador) o un material tradicional (ejercicio en papel y escrito).

Eletrodo de hidrogênio: o que há nos livros didáticos além de E¸ = 0?

The results of an exercise on electrochemistry for General Chemistry students are presented. The difficulty encountered by students in predicting the shift in the potential of the hydrogen electrode under non-standard conditions prompted a search in textbooks on how the subject is developed. Besides several instances of inconsistencies in defining the standard state, such as including the temperature in the definition, a number of incorrect depictions of the hydrogen electrode were discovered. Of the 28 General Chemistry books, 16 Physical Chemistry books and 24 Internet pages, 30, 20 and 46%, respectively, showed devices that would not work in practice.

Investigando a presença da história da ciência em livros didáticos de Química Geral para o ensino superior

This paper aims at analyzing the history of science content of three general chemistry textbooks used in Brazilian universities: the translations of Kotz and Treichel's Chemistry & Chemical Reactivity, Atkins and Jones's Chemical Principles, and Garritz and Chamizo's Química. Results revealed different trends for the inclusion of history of science in chemistry teaching. Kotz & Treichel and Atkins & Jones used history mainly as curiosity and ornament. Garritz & Chamizo adopted the historical approach as one of the organizing axis of their textbook. Nevertheless, the historical content of the three textbooks may be criticized from current historiographical standpoint.

O que sabemos sobre os primeiros livros didáticos brasileiros para o ensino de Química

This paper deals with the Brazilian textbooks of Chemistry from the XIX century to 1930. After presenting the science and its teaching contexts in Imperial Brazil and describing the first Chemistry textbook written by a Brazilian, the state of knowledge about these prime Brazilian books is presented. These works show the texts had strengths overlooked by current materials, a fact confirmed by analyzing textbooks from three authors from the period. The study concludes by compiling a list of 50 titles of early Chemistry books to help guide future research.

ANÁLISE DA ABORDAGEM HISTÓRICA PARA A TABELA PERIÓDICA EM LIVROS DE QUÍMICA GERAL PARA O ENSINO SUPERIOR USADOS NO BRASIL NO SÉCULO XX

The aim of this paper was to analyze the historical approaches to the periodic table in general chemistry textbooks used in Brazilian universities in the twentieth century. Textbooks were qualitatively analyzed according to the following criteria: position of the discussion about the periodic table in the book; presence or absence of a specific chapter on the subject; presentation of attempts to classify chemical elements before Mendeleev; presentation of the construction process of the periodic table by Mendeleev; identification of problems in the original table; discussion of Mendeleev's predictions about unknown elements; organization of the periodic table; periodic properties presented and discussed; and the enunciation of the periodic law. The analysis revealed different approaches at specific periods of the twentieth century, from more descriptive approaches to emphasis on attempts to explain the periodic table in terms of atomic orbitals. These changes point to different ways of understanding chemistry during the period studied.

As faces do livro de leitura

Este trabalho pretende ser uma contribuição para a compreensão da história do livro didático no Brasil, mais especificamente no tocante ao estado de São Paulo. Trata-se da análise de alguns dos livros de leitura mais utilizados nas escolas primárias no final do século XIX e início do XX (1890-1920), compreendendo o livro como um objeto cultural. Delineamos as suas diferentes faces e o seu uso na escola, considerando o conteúdo, a finalidade, o formato, a produção editorial e a autoria, fazendo a interseção entre a história das disciplinas escolares e a história da leitura.
