A tecnologia digital é uma grande promessa para o ensino de Química na escola, acredita-se que a implementação dessas tecnologias produz melhoria na educação. No entanto, pouco se sabe sobre a articulação coordenada dos aplicativos para smartphone propostos para este fim e as demais representações semióticas tradicionais da Ciência e efeitos sobre a aprendizagem dos alunos. É importante acrescentar que a escola ainda não conseguiu integrar todas as mudanças da sociedade com a rápida evolução das tecnologias, afastando-se dos jovens inseridos nessa evolução. Ao professor se exige um esforço para a readaptação a essa integração, o papel desse educador deverá ser ativo e responsável no enquadramento pedagógico das tecnologias, para que possa tornar-se um meio de renovação do ensino e não apenas um mero reforço de práticas tradicionais. Atualmente, na área da Educação Química, nota-se que a informatização e os aplicativos tão acessíveis a qualquer classe da população, podem proporcionar situações de aprendizagem que acabavam restritas, pelo alto custo. Nesse contexto e, com o objetivo de conhecer os aplicativos para a Educação Química e o crescimento de sua oferta para incentivar sua adoção na educação, são trazidos, nesse artigo, os resultados de uma pesquisa sobre aplicativos para Android® relacionados à área, realizada a partir da busca de aplicativos em repositórios livres tais como Free and Open Source Software - FOSS® e Google Play® disponíveis em um período de 2012 a 2016, apresentando a evolução do número de aplicativos disponíveis, os temas mais recorrentes e indicando aplicativos para a Educação Química. Palavras-chave: Ensino. Química. Aplicativos. Smartphone. Tecnologia Digital AbstractThe use of digital technology holds great promise for teaching chemistry in school, it is believed that the implementation of this new technology produces education improvement. However, little is known about the coordinated joint applications for smartphone proposed for this objective and other traditional Sciences semiotic representations and effects on the students’ learning. It is important to add that the school was still not able so far to integrate all the changes in society with the rapid technology evolution, moving away from our young people who are inserted into this evolution. To the teacher, it is required an effort to rehabilitate this integration, the educator’s role should be active and responsible in the technologies educational environment, so they can become a means of teaching renewal and not just a mere reinforcement of traditional practices. Currently, in the Chemical Education area, it is noted that the computerization and applications so accessible to any class population can provide learning situations which used to be limited due to theirhigh cost. In this context and in order to knowthe Chemistry Education applications and the growth supply to encourage their adoption in education, are coveredin this article, the results of a survey on applications for Android® related to the area, accomplished from search applications for free repositories such as Free and Open Source Software - FOSS® and Google Play® available in a period from 2012 to 2016, showing the evolution of the number of available applications, the most recurrent themes and indicating applications for Chemical Education.Keywords: Education.

In today's world, the heart of modern technology is software. In order to compete with pace of new technology, changes in software are inevitable. This article aims at the association between changes and object-oriented metrics using different versions of open source software. Change prediction models can detect the probability of change in a class earlier in the software life cycle which would result in better effort allocation, more rigorous testing and easier maintenance of any software. Earlier, researchers have used various techniques such as statistical methods for the prediction of change-prone classes. In this article, some new metrics such as execution time, frequency, run time information, popularity and class dependency are proposed which can help in prediction of change prone classes. For evaluating the performance of the prediction model, the authors used Sensitivity, Specificity, and ROC Curve. Higher values of AUC indicate the prediction model gives significant accurate results. The proposed metrics contribute to the accurate prediction of change-prone classes.

Abstract Long in the making, computational chemistry for the masses [J. Chem. Educ. 1996, 73, 104] is finally here. Our brief review on various free and open source software (FOSS) quantum chemistry packages points out the existence of software offering a wide range of functionality, all the way from approximate semiempirical calculations with tight-binding density functional theory to sophisticated ab initio wave function methods such as coupled-cluster theory, both for molecular and for solid-state systems. Combined with the remarkable increase in the computing power of personal devices, which now rivals that of the fastest supercomputers in the world of the 1990s, we demonstrate that a decentralized model for teaching computational chemistry is now possible thanks to FOSS computational chemistry packages, enabling students to perform reasonable modeling on their own computing devices, in the bring your own device (BYOD) scheme. FOSS software can be made trivially simple to install and keep up to date, eliminating the need for departmental support, and also enables comprehensive teaching strategies, as various algorithms' actual implementations can be used in teaching. We exemplify what kinds of calculations are feasible with four FOSS electronic structure programs, assuming only extremely modest computational resources, to illustrate how FOSS packages enable decentralized approaches to computational chemistry education within the BYOD scheme. FOSS also has further benefits: the open access to the source code of FOSS packages democratizes the science of computational chemistry, and FOSS packages can be used without limitation also beyond education, in academic and industrial applications, for example. For these reasons, we believe FOSS will become ever more pervasive in computational chemistry.

The World

AbstractThe development of new technology has spawned different ideas and new approaches to engaging with people around the world. One such development is the ability to approach public diplomacy based on the methodology employed in the production of open-source software. This approach provides the means to engage with communities of other concerned actors, communicatae through human voices, place emphasis on understanding lessons from previous initiatives, and vitally engage on the bases of the interests of those communities. Ideas can no longer be seen as owned by a country; mass communication provides the means to see beyond national claims of unity. Recognizing this and embracing the means to engage with communities that are defined by ideology rather than physical borders provides the potential to render public diplomacy initiatives more relevant to the target audience and ultimately more influential.

In this article I use actor–network theory to make sense of some of the characteristics given to the XO by the OLPC Project; namely its immense scale, the involvement of educational bureaucracies (and the contradictions this entails), the role of children and the open source software community. I also identify several social forces that will likely shape the direction this technology takes. The future of the XO is, as a result of these forces, by no means certain. What will help determine the trajectory it takes is how willing the OLPC team is to further negotiate the meaning of this new technology.
