This article analyzes the specific features and processes of indexing and classification performed in school libraries to process and retrieve information from their collections. Subject languages used in Spanish, Portuguese and Brazilian Portuguese school libraries are also analyzed. To achieve this goal, the concept of school library was analyzed, its function was studied and the techniques and tools that allow the information organization were examined. Among the tools, we studied the Subject Headings Lists for children and juveniles’ books and the Subject Headings List for public libraries, the Universal Decimal Classification System (paperback edition) or the classification by fields of interest and specialized thesauri like the Tesauro de la Educación UNESCO-OIE and the TesauroEuropeo de la Educación.

This study explores, in 3 steps, how the 3 main library classification systems, the Library of Congress Classification, the Dewey Decimal Classification, and the Universal Decimal Classification, cover human knowledge. First, we mapped the knowledge covered by the 3 systems. We used the “10 Pillars of Knowledge: Map of Human Knowledge”, which comprises 10 pillars, as an evaluative model. We mapped all the subject-based classes and subclasses that are part of the first 2 levels of the 3 hierarchical structures. Then, we zoomed into each of the 10 pillars and analyzed how the three systems cover the 10 knowledge domains. Finally, we focused on the 3 library systems. Based on the way each one of them covers the 10 knowledge domains, it is evident that they failed to adequately and systematically present contemporary human knowledge. They are unsystematic and biased, and, at the top 2 levels of the hierarchical structures, they are incomplete.

We analysed the written statements of libraries that have adopted the bookstore model for coherence or lack of coherence with common public library guidelines. We used a text-based Foucauldian genealogical discourse analysis to investigate the written statements used by libraries that have adopted BISAC and other aspects of the bookstore model. Libraries adopting bookstore models such as BISAC should consider the potential consequences of adopting a commercial model for a public entity. This paper has practical implications for libraries considering adopting any aspect of the bookstore model, but especially the BISAC system, as it examines the potential benefits and drawbacks of the bookstore model popular in some libraries with respect to the purposes and goals of public libraries. BISAC application in libraries seems to be part of a trend of applying commercial practices, values and terminology in libraries, perhaps not with the purpose of replacing libraries with bookstores, but with the aim for both systems to converge into a new kind of commercial entity and context. The influence of one kind of system over the other does not seem to be totally reciprocal, since the application of library practices, values and standards in bookstores has not had the same effects and resonance as has occurred in the opposite direction.

This research aims at examining the relationship between the performance of elementary school students Cycle I in problem solving and attitudes toward mathematics. For this, a research was conducted at a state school in the city of Bauru which was selected for convenience. Participants were randomly selected consisting of 75 students, of whom 21 were third years and 57 were of three classes of fifth year. The instruments used for data collection were: a informative questionnaire to characterize the students in age, grade, favorite subjects and the least liked, among others, an attitude scale, Likert type, to examine the attitudes toward mathematics; a interviews with 11 selected students according to scores on the attitudes and mathematical problems to be solved through the method of thinking aloud. The results showed that the major difficulties encountered by students in solving problems were: to understand the problems, formalizing the reasoning, recognize in the problem the algorithms needed for its resolution, make calculations with decimal numbers, do combinatorics, using the sum of equal portions instead of multiplying, self-confidence and autonomy in what he was doing, and others; participants with positive attitudes towards mathematics showed greater confidence to solve problems as well as a greater understanding on what was required by them, but were not detected significant relation between the attitudes and performance, since it was unfavorable
