Context Early sports sampling is associated with superior biomechanics in youth athletes; however, the effect of multisport participation on adult biomechanics is unknown. Objective To compare jump-landing biomechanics between adult recreational athletes who previously participated in 0, 1, or 2 or more select high school varsity sports (VSs; basketball, lacrosse, soccer, volleyball) that feature landing and cutting tasks. Design Descriptive laboratory study. Setting University community setting. Patients or Other Participants Fifty adult recreational athletes (22 women, 28 men; age = 23.8 ± 2.5 years) with no high school VS experience or with high school VS experience in basketball, lacrosse, soccer, or volleyball. Athletes were grouped into those who participated in 0 (0VS, n = 11), 1 (1VS, n = 21), or 2 or more (2VSs, n = 18) of these sports at the high school level. Main Outcome Measure(s) The average Landing Error Scoring System (LESS) total score from 3 individual jump landings was determined. A 1-way analysis of covariance using sex as the covariate was calculated to compare groups. The Pearson R was used to test for the correlation between the LESS score and number of sports played, and a linear regression analysis was performed using the number of sports played to predict the LESS score. The α level was set a priori at .05. Results The 0VS athletes produced similar LESS scores as the 1VS athletes (5.89 ± 1.2 versus 5.38 ± 1.93 points, respectively, P = .463), whereas the 2VSs athletes demonstrated lower LESS scores (3.56 ± 1.97 points) than the 0VS (P = .002) and 1VS (P = .004) athletes. The LESS scores were moderately negatively correlated with the number of high school VSs played (R2 = −0.491, P < .001). The linear regression analysis was significant (F1,37 = 9.416, P = .004) with R2 = 0.203. For every additional VS played at the high school level, the LESS score decreased by 1.28 points. Conclusions Landing Error Scoring System scores were lower in athletes who had a history of multisport high school varsity participation in basketball, lacrosse, soccer, or volleyball compared with those who had a history of single-sport or no participation in these sports at this level. Multisport high school varsity participation in these sports may result in improved neuromuscular performance and potentially reduced injury risks as adults.

“Every body perseveres in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed thereon” (p. Newton 1846, p. 83). This is the famous first axiom or law of motion stated by Newton in his masterpiece The Mathematical principles of natural philosophy (ivi). Everywhere, in the courses of physics at the high school level the inertia principle is the first to be taught. However, there are many doubts that most of learners fully grasp its numerous and fundamental nuances, which are necessary for a satisfying introduction to physics. Therefore, I propose an interdisciplinary approach for the explanation of this principle in which history of science and analysis of the daily experiences are joined to offer a complete comprehension of the concept of inertia.

RESUMO O ensino da segunda lei da termodinâmica e do seu conceito, associado à entropia, tem sido considerado problemático por vários autores. Nesse trabalho iremos compilar os problemas levantados por alguns destes autores na perspectiva de sintetizar as questões e soluções sugeridas, como forma de ampliar a discussão sobre como tratar didaticamente a segunda lei da termodinâmica e a entropia na Física do ensino médio. Fizemos um breve levantamento da abordagem dada ao assunto pelos livros didáticos e propomos que a história e a epistemologia da ciência tenham um papel estruturante em uma prática educativa pautada pelo diálogo. Sugerimos, como parte da construção de um caminho para a entropia, o estabelecimento de três momentos epistemológicos dentro da história da termodinâmica. Esses três momentos serão os balizadores de uma abordagem mais significativa no sentido de que a história da ciência não tenha apenas um papel periférico para o estudo da segunda lei e da entropia. Palavras-chave: Termodinâmica, entropia, ensino, história da ciência. TEACHING ENTROPY IN SECONDARY PHYSICS: ANALYSIS OF TEXTBOOKS AND A HISTORICAL APPROACH. ABSTRACT Many authors consider teaching the second law of thermodynamics historically problematic. In this paper we will compile problems raised by some of these authors in the perspective of synthesizing questions and solutions suggested, as a mean to widen the discussion on how to treat didactically the second law and entropy in high school level. We did a brief review on how textbooks approach this subject and came to a conclusion that the history of science and the study of relationships among, science, technology and society should be considered as integrating part of any didactical approach grounded in a dialogical educational view. We suggest as part of a way to entropy, the establishment of three epistemological moments within the history of thermodynamics. These three moments will serve as guiding elements for a more meaningful approach, in a sense that the history of science will not only play a peripheral role in the didactic treatment of entropy and the second law of thermodynamics. Keywords: Thermodynamics, entropy, teaching, history of science.

Several recent articles in this journal and in other NCTM publications indicate a continuing interest in alternatives to the straightedge-and-compass constructions of traditional high school geometry (see Bibliography). A description of various construction tools and techniques may be found in the literature (Eves 1963; Yates 1949), and the history of the topic from the time of the Greeks to the present is a fascinating one. Of the simple construction instruments, one of the least well known is the ruler with two parallel straightedges (a parallel ruler). In 1890, Adler (1906) showed that all the ruler-and-compass constructions can be done using only a ruler with two edges at a fixed angle; the parallel ruler is the special case with angle zero. There does not seem to be a treatment of constructions with the parallel ruler that is at once reasonably complete and accessible to high school geometry students. Most discussions make use of terminology and theorems beyond that usually covered at the high school level, and, further, much of even this material, such as Yates’s Geometrical Tools, is now out of print—surely an undeserved fate for so delightful a book.

El objetivo de este trabajo es el de identificar y analizar los factores que subyacen en el nivel de satisfacción de los usuarios de centros deportivos municipales que realizan actividades dirigidas y compararlo con aquellos usuarios que no hacen uso de este servicio. Los datos fueron recogidos de una encuesta entre los clientes de centros deportivos municipales, de los que 536 sujetos  manifestaron realizar actividades dirigidas en el centro. Las mujeres y los usuarios con un nivel de estudios secundarios son los que más utilizan estos servicios. Un análisis factorial aplicado revela tres dimensiones que contribuyen a la satisfacción, en ambos casos, pero la composición de cada uno de ellos es diferente. Finalmente, del análisis de regresión múltiple se desprende que un gerente debe prestar atención, en primer lugar, a la calidad de las instalaciones y la comunicación ya que fueron el mejor predictor de la satisfacción. The aim of this work is to identify and analyze the factors that underlie the level of satisfaction of users of municipal sports centers that conduct directed activities and compare it with those users who do not use this service. Data were collected in a survey among users of municipal sports centers, of which 536 subjects stated that they carried out directed activities at the center. Women and users with a high school level are the ones who use these services the most. An applied factor analysis reveals three dimensions that contribute to satisfaction, in both cases, but the composition of each of them is different. Finally, the multiple regression analysis shows that a manager must pay attention, first of all, to the quality of the facilities and communication since they were the best predictor of satisfaction.

En este artículo son presentados resultados parciales de una investigación que tomó como base epistemológica los estudios sobre fuentes históricas textuales discutidos por Barros (2004), en este caso, el Códice Atlántico de Leonardo da Vinci con foco en el uso de la historia para la enseñanza de la Matemática. El objetivo central fue interpretar las imágenes representadas en la hoja 100r en busca de las relaciones geométricas que puedan emerger, con el fin de movilizarlas para las aulas de matemática (enseñanza de la geometría) en la Educación Básica, por medio de la problematización de los dibujos y anotaciones en la hoja. El material fue una copia impresa del manuscrito de Da Vinci que contienen 111 hojas e dibujos y anotaciones dentro de las cuales, en este artículo, analizamos la hoja 100r en la cual Leonardo presenta dos temas centrales: la duplicación del cuadrado y las relaciones entre los volúmenes de sólidos. La investigación documental realizada tuvo como fundamentos para la interpretación del lenguaje registrado en la hoja estudiada, elementos de la semiótica de C. S. Peirce a partir de Santaella (1995, 2012). Los resultados apuntan para la posibilidad del establecimiento de relaciones entre la geometría reflejada en el Códice Atlántico de Leonardo da Vinci y la geometría de la Educación Básica con foco en la elaboración de actividades de enseñanza a partir de la problematización (Miguel Mendes, 2010) de la geometría histórica identificada en el Códice Atlántico.Palabras clave: Historia de las matemáticas, Enseñanza de las matemáticas, Geometría, Leonardo da Vinci. DUPLICATION OF THE SQUARE AND THE VOLUME OF SOLIDS IN LEONARDO DA VINCI'S ATLANTIC CODEX: A STUDY OF THE 100r SHEET AbstractThis article presents partial results of a wider research whose epistemological foundations were the studies on historical text sources discussed by Barros (2004), and which was based on Leonardo da Vinci’s Atlantic Codex, focusing on History for the teaching of Mathematics. The main objective was to interpret the images presented on leaf 100r, aiming to find possible geometric relations, and mobilize them during mathematics classes – namely, in geometry lessons – both in Elementary and High School, problematizing the drawings and notes in the aforementioned leaf. Our source was a printed copy of Da Vinci’s manuscript containing 1119 leaves of drawings and notes. Among these is leaf 100r, which we analyze in this article. In it, Leonardo presents two central themes: the duplication of the square and the relations between solid volumes. The documented research we accomplished based the interpretation of the language used in leaf 100r on some elements of C. S. Peirce’s semiotics, as defined by Santaella (1995, 2012). The results point out the possibility of establishing relations between the geometry we find on Leonardo da Vinci’s Atlantic Codex and the geometry studied at the Elementary and High School level, focusing on the elaboration of teaching activities based on the problematization (Miguel Mendes, 2010) of the historical geometry one finds on the Atlantic Codex.Keywords: History of Mathematics, Mathematics teaching, geometry, Leonardo da Vinci. A DUPLICAÇÃO DO QUADRADO E O VOLUME DE SÓLIDOS NO CÓDICE ATLÂNTICO DE LEONARDO DA VINCI: UM ESTUDO DA FOLHA 100r ResumoO presente artigo apresenta resultados parciais de uma pesquisa mais ampla, que tomou como base epistemológica os estudos sobre fontes históricas textuais discutidos por Barros (2004), concretizado no Códice Atlântico de Leonardo da Vinci, com foco no uso na história para o ensino de Matemática.

<p>Radicalism is a challenge and concern for the world, including the Muslim community in Indonesia. The radicalism movement is evidenced by the existence of violence in achieving its goals in political, religious, social, educational, and economic matters. In the world of education in Indonesia, violence, and intimidation still often occurs so that anti-radicalism education is needed which can be realized through the teaching process, especially at the high school level. Anti-radicalism education requires humans to respect each other's differences and make peace according to the Al-Quran and Hadith guidelines which are integrated through education. For this reason, the analysis in this article is descriptive qualitative with an approach using the library method which aims to understand the history of the development of the Islamic radicalism movement and Islamic solutions to overcome the problems of religious radicalism and terrorism by implementing anti-radicalism education. Besides, this article will describe some of the terminology and examples of the influence of the Islamic radical movement at the senior high school. In Indonesia, the emergence of Islamic radicalism is based on three factors, namely developments at the global level, namely the radical group from the Middle Eastern. Second, the widespread of Wahhabi has led to conflict. And the third is poverty. The field of education also has an impact on Islamic radicalism, which can be from teachers to students, the influence of technological sophistication, the influence of Wahhabi understanding, poverty, even the materials in student worksheets and books also contain many radical values. Therefore, anti-radicalism education is very important because it can require the younger generation to respect differences, humans who love compassion, and humans who hate doing damage. Efforts to overcome radicalism at high school levels can be done with character education</p>
