ResumoO presente artigo faz parte de uma pesquisa de mestrado, em andamento, vinculada ao Programa de Pós-Graduação em Ensino de Ciências e Matemática (PPGECIMA), na Universidade Federal de Sergipe (UFS). A pesquisa de mestrado teve, dentre outros objetivos específicos, investigar as três dimensões do problema didático (epistemológica, econômica e ecológica) dos sólidos geométricos. Assim, o objetivo deste artigo é apresentar um primeiro estudo das dimensões econômica e ecológica do objeto matemático sólidos geométricos. Para tanto, inicialmente, realizou-se um estudo histórico do ensino de Geometria no Brasil. Em seguida, investigou-se como os sólidos geométricos estão presentes em documentos curriculares oficiais – Parâmetros Curriculares Nacionais (PCN) e Base Nacional Comum Curricular (BNCC) – implementados nas últimas duas décadas do presente século. Logo, o estudo teve como aporte teórico as investigações de autores que versam sobre a Teoria Antropológica do Didático (TAD) e as dimensões que distinguem os problemas didáticos de pesquisa, formação docente e problemáticas do ensino de Geometria. Nesse primeiro ensaio, foi possível identificar que, em relação aos sólidos geométricos, pouco se evoluiu em relação ao seu ensino na educação básica. Além disso, observa-se que a problemática quanto ao ensino de Geometria, apesar da tentativa dos documentos curriculares e da comunidade acadêmica, não foi superada. Palavras-chave: Sólidos Geométricos. Histórico do Ensino de Geometria. Modelo Epistemológico de Referência. AbstractThis article is part of a master's research, in progress, linked to the Graduate Program in Science and Mathematics Teaching (PPGECIMA), at the Federal University of Sergipe (UFS). The master's research had, among other specific objectives, to investigate the three dimensions of the didactic problem (epistemological, economic and ecological) of geometric solids. Thus, the objective of this article is to present a first study of the economic and ecological dimensions of the geometric solid mathematical object. Therefore, initially, a historical study of the teaching of Geometry in Brazil was carried out. Then, it was investigated how the "geometric solids" are present in official curricular documents - National Curriculum Parameters (PCN) and Common Base National Curriculum (BNCC) - implemented in the last two decades of the present century. Therefore, the study had as theoretical support the investigations of authors that deal with the Anthropological Theory of Didactics (TAD) and the dimensions that distinguish the didactic problems of research, teacher training and problems of the teaching of Geometry. In this first test, it was possible to prove that in relation to geometric solids little progress has been made in relation to its teaching in basic education. In addition, it is observed that the problem regarding the teaching of Geometry, despite the attempt of curricular documents and the academic community, has not been overcome. Keywords: Geometric Solid. History of Geometry Teaching. Epistemological Reference Model.

On the one hand, ensuring that students archive adequate levels of Mathematical knowledge by the time they finish basic education is a challenge for the educational systems in several countries. On the other hand, the pervasiveness of computer-based devices in everyday situations poses a fundamental question about Computer Science being part of those known as basic sciences. The development of Computer Science (CS) is historically related to Mathematics; however, CS is said to have singular reasoning mechanics for problem solving, whose applications go beyond the frontiers of Computing itself. These problem-solving skills have been defined as Computational Thinking skills. In this chapter, the possible relationships between Math and Computational Thinking skills are discussed in the perspective of national curriculum guidelines for Mathematics of Brazil, Chile, and United States. Three skills that can be jointly developed by both areas are identified in a literature review. Some challenges and implications for educational research and practice are also discussed.

In the article we seek to address questions regarding the interest of graduates of a degree course in Natural Sciences and Mathematics in relation to the teaching career in basic education. The course enables its graduates to work in the subjects Science and Mathematics in the final years of elementary school and Mathematics, Physics and Chemistry in high school. Our intention is to identify and reflect on the perceptions of these graduates about teaching, highlighting with this inherent aspects to the exercise of this profession in basic education. From the application of questionnaires to graduates of this course, we produced data regarding their performance in basic education, which enabled us to reflect on the national scenario in relation to the exercise of this profession. We could observe that the majority of the students participating in the research are not working in basic education and that the current scenario of devaluation of the teaching career exerts a significant influence in the decision making process of choosing or not the teacher profession for professional performance after graduation.

Background. Recently, non-presintered chromium-cobalt (Cr-Co) blocks with the commercial name of Ceramill Sintron were introduced to the market. However, comprehensive studies on the dimensional accuracy and fit of multi-unit frameworks made of these blocks using the coordinate measuring machine (CMM) are lacking. This study aimed to assess and compare the dimensional changes and fit of conventional casting and milled frameworks using Ceramill Sintron. Methods. A metal model was designed and scanned and 5-unit frameworks were fabricated using two techniques: (I) the conventional casting method (n=20): the wax model was designed, milled in the CAD/CAM machine, flasked and invested; (II) the milling method using Ceramill Sintron blocks (n=20): the wax patterns of group 1 were used; Ceramill Sintron blocks were milled and sintered. Measurements were made on the original reference model and the fabricated frameworks using the CMM in all the three spatial dimensions, and dimensional changes were recorded in a checklist. Data were analyzed with descriptive statistics, and the two groups were compared using one-way ANOVA and Tukey test (α=0.05). Results. The fabricated frameworks in both groups showed significant dimensional changes in all the three dimensions. Comparison of dimensional changes between the two groups revealed no significant differences (P>0.05) except for transverse changes (arch) that were significantly greater in Ceramill Sintron frameworks (P<0.05). Conclusion. The two manufacturing processes were the same regarding dimensional changes and the magnitude of marginal gaps and both processes resulted in significant dimensional changes in frameworks. Ceramill Sintron frameworks showed significantly greater transverse changes than the conventional frameworks.

The History of Nursing and Health Knowledge Study Group linked to the Graduate Nursing Program at the Federal University of Santa Catarina, has been producing knowledge on this subject over the past 15 years. This documentary study presents an assessment of the group's master's theses and doctoral dissertations conducted between 1995 and 2010. A total of 23 master's theses and 12 doctoral dissertations were developed. The group has contributed on many fronts, whether with scientific production that embodies innovative content taught to students, or with the dissemination of its studies' results, which gives greater visibility to its members translates into invitations for them to participate in scientific events and on editorial boards. There is a need to move toward greater integration with other research groups in the field of history and sensitize the academic community to the importance of nursing history.

The STEM subjects (Science, Technology, Engineering, and Mathematics) are very important for education, but the lack of experimental laboratories for these subjects in a school might decrease the interest of its students in STEM fields. This chapter explores these issues in the Brazilian context where, in order to address this issue, remote experiments are used to share real experiments manipulated through the Internet. Teachers and students can use remote laboratories, equipped with real experiments, to put in practice theoretical concepts learned in class. This chapter presents a report on a pilot project that aims to explore the use of Mobile Remote Experimentation (MRE) by teachers and students of public high schools in Brazil. It involves the use of mobile devices to access remote experiments in STEM subjects through the Internet. The report demonstrates the effectiveness of using such educational resources to improve pedagogical results by applying the TPACK (Technological Pedagogical Content Knowledge) model to measure the impact of MRE by STEM teachers.

Since the introduction of the No Child Left Behind (NCLB) Act of 2001, education in the United States has, in the words of President Bush, been seen as “a national priority and a local responsibility.” The first of the four basic education reform principles stated in the NCLB Act is local accountability for results. The second principle, flexibility and local control, empowers states to create their own standards and to test every student’s progress using tests aligned with these standards. In addition, there are also programs to promote the alignment of technology with educational goals within the NCLB legislation. In more and more states, school performance is assessed by means of a standardized assessment test which is designed to assess the academic level of students, schools, and districts. It is also intended to assist in identifying students’ strengths and weaknesses and to foster improvements in academic achievement. In one such state (that will remain anonymous) the reading and mathematics portions of the exam are administered to grades 5, 8, and 11.
