Apresenta-se, neste artigo, uma análise da resolução de uma questão sobre números racionais, exposta por estudantes ingressantes no Ensino Médio. O objetivo foi identificar as principais dificuldades e erros apresentados pelos participantes sobre o conceito e operações de números racionais. Para isso, realizou-se uma análise de erros das resoluções apresentadas pelos participantes. A interação de aspectos algorítmicos, intuitivos e formais é o referencial teórico adotado nas análises. Verificou-se que os estudantes não possuem clareza sobre o conceito de número racional e apresentam, em decorrência, dificuldades no uso dos procedimentos algorítmicos necessários para a resolução da questão proposta. Palavras-chave: Números racionais. Análise de erros. Dificuldades. Interpretação.   Difficulties of high school entrants in understanding rational numbers Abstract This paper presents an analysis of the resolution of a question about rational numbers, posed by students entering high school. The goal was to identify the main difficulties and errors presented by the participants about the concept and operations of rational numbers. To do so, an error analysis of the resolutions presented by the participants was performed. The interaction of algorithmic, intuitive and formal aspects is the theoretical framework adopted in the analysis. It was found that students do not have clarity about the concept of rational numbers and present, as a result, difficulties in the use of algorithmic procedures necessary to solve the proposed question. Keywords: Rational numbers. Error analysis. Difficulties. Interpretation.

Twitter represents a virtual, global classroom of collective intelligence and an epistemological shift in which the “experts” in the exchange are not necessarily the traditional teachers. The experts on Twitter are those who share information of value and do so often, a definition that could and should include students engaging the medium for academic purposes. As an academic tool, Twitter offers students the opportunity to engage in a wider discourse than the classroom environment and to gain confidence in their knowledge and potential “expert” status. Furthermore, the nature of Twitter closely aligns with Tapscott’s (2009) identified norms for the Net Generation, which includes current high school and college-aged students. The eight norms—freedom, customization, scrutiny, integrity, collaboration, entertainment, speed, and innovation—provide an appropriate theoretical framework for a curriculum-related question such as: What is the value of implementing Twitter into classroom instruction?

Immigration Regulation

The focus of this article is an educational encounter during a social science project at a junior high school in Norway. The topic of the school project was the Norwegian Constitution of 1814. In this Constitution, many of the ideas of the French and American revolutions had been adopted, e.g. popular sovereignty and the separation of power. Nevertheless, the Constitution also reflected intolerant ideas, especially with regards to the so-called Jews-paragraph, whereby Protestantism was proclaimed, and Jews were excluded from the Norwegian state. In the educational encounter analyzed in this article, I argue that the notion of an exceptional Norwegian democracy affects the narrative constructed about the Norwegian Constitution. This notion serves to exclude the Jews-paragraph from the narrative. The postcolonial concept of Nordic exceptionalism constitutes an important theoretical framework for the analyses of the educational encounter. In the contemporary Norwegian society, immigration regulation by laws again has relevance. This article, therefore, discusses the critical classroom conversations thematizing the Jews-paragraph could have led to, by pointing at different historical and present-day topics of relevance. The discussion implicates the importance of recognizing the role and impact state-led control, violations and exclusion of minorities have in Norwegian history. Not recognizing these aspects of history can lead to the production and reproduction of idealized and exceptional national narratives.

Geometry Test

In solid geometry needed the ability to visualize space that cannot be seen so differences in visual intelligence can trigger errors in solving geometry problems. Therefore, this study aimed to determine the types of errors made by students and the factors that cause errors in working on geometry problems based on Newman's Error Analysis (NEA) in terms of visual intelligence. This research chose the subjects of class XII high school who had studied the material distance points to lines in space with different levels of visual intelligence, namely high and low. The process of collecting data used visual intelligence test questions, geometry test questions, and interviews. The results of this study indicated that the level of students' visual intelligence affects the difference in location and the factor that causes errors in the stage of transformation especially on determining the distance in dimension 3. Students with high visual intelligence made mistakes at the stage of transformation and encoding that caused by the students’ carelessness. However, students with low visual intelligence made mistakes at the stage of comprehension, transformation, process skills, and encoding due to the concept of the point distance to the line and the concept of the Pythagorean theorem.

Diagnostic Research

The purpose of the following article is to discuss the theoretical framework of diagnostic research used in glottodidactics as well as to analyze some selected diagnostic studies conducted by Polish and German researchers in the last decade into the development of high school and university students’ and foreign language teachers’ intercultural competence. In the last part of this article attention is paid to the presentation and discussion of the most frequent problems which researchers encounter while planning and carrying out diagnostic studies.

This chapter describes a children’s book project in which high school students used technology to create e-books for younger students. The benefits of the project for both younger and older students are discussed. Older students developed technology and writing skills; younger students developed letter writing and reading skills. The process is also detailed in the hope that others who might be interested in replicating the project in their own classroom would be able to do so.

Do So

To understand cultural differences, we need to find ways to characterize the variations in the social contexts in which people are located. To do so, we must focus on differences between contexts rather than differences between individuals. Most research of this type has examined differences between nations in terms of dimensions. Treating each nation as a unit, contrasts have been identified in terms of values, beliefs, self-descriptions, and social norms. The most influential difference identified concerned the dimension of individualism–collectivism, which has provided the theoretical framework for numerous studies. The validity of this type of investigation rests on close attention to aspects of measurement to ensure that respondents are able to make the necessary judgments and to respond in ways that are not affected by measurement bias. Where many nations are sampled, multilevel modeling can be used to show the ways in which dimensions of culture affect social behaviors.

In the height of autumn, the City of Peachtree Street in the Peach Tree State will be the locale of the Atlanta Meeting of the National Council of Teachers of Mathematics. This event, a first of its kind for Atlanta and for Georgia, is designed to attract persons interested in mathematics, kindergarten to the college level. From geometry in the kindergarten to probability and statistics in high school; from the rational numbers in the elementary school to applications of mathematics in the senior high school, from the role of reading to the role of the administrator in improving mathematics education; in short, whatever aspects of mathematics on the school and college levels fascinate one will be presented during the Atlanta Meeting, November 19-21, 1964.

Twenty years ago one heard very little about “guidance” in high school mathematics. Many students took mathematics only because they were required to do so, or because they were told it was good for them. Other students took no mathematics- having been misguided by wellmeaning adults. World War II temporarily usurped the role of guidance counsellor. There was little doubt as to what had to be done.
