El trabajo colaborativo como estrategia didáctica para la enseñanza/aprendizaje de la programación: una revisión sistemática de literatura

Abstract: The incorporation of Collaborative Work into programming courses has been identified as a potential strategy that could maximize student participation and have a positive impact on learning. In the consulted sources, no study has been found to collect and analyze the results of research on this subject using a systematic method. To try to fill this gap, a systematic literature review was conducted with the aim of summarizing the studies on the use of Collaborative Work as a didactic strategy for teaching/learning programming. Initially, through a search in four (4) databases of scientific publications, 95 studies published in the last five (5) years were obtained. After careful analysis of each one of them, only 40 were found to meet the review requirements. This analysis resulted in the synthesis of eleven (11) Collaborative Learning Techniques (CLT) that implement such strategy. Subsequently, they were grouped into 19 common names of strategies found in the documents, i.e. the collaborative strategies or techniques associated with each study. The review also showed a significant amount of contributions from the research community that constitute an important basis for future work. This demonstrates that Collaborative Work is increasingly consolidated as a valid and relevant didactic strategy, not only in programming teaching/learning, but also in other areas of knowledge including computer science.

Adsorción de metales pesados en aguas residuales usando materiales de origen biológico

Abstract: Biosorption is a process that allows active or passive uptake of metal ions due to the property that different living or dead biomass have to bind and accumulate these pollutants by different mechanisms. The application of low-cost materials obtained from different biomass from microbial flora, agro-industrial waste and algae has been investigated to replace the use of conventional methods for the removal of contaminants such as heavy metals. Some of the metals of greatest impact to the environment due to its high toxicity and difficult to remove are chromium, nickel, cadmium, lead, and mercury. In this paper, an overview of adsorption as an alternative process for the removal of contaminants in solution and biomass commonly used in these processes, as well as some of the modifications made to improve the efficiency of adsorption of these materials is presented. It was concluded that the use of adsorption in the removal of pollutants in aqueous solution using waste biomass is applicable to these decontamination processes avoiding subsequent problems such as the generation of chemical sludge, and generating an alternative to use materials considered as waste. It is further identified that such factors as the pH of the solution, particle size, temperature, and concentration of metal effect on the process.

La Modelación como Proceso en el Aula de Matemáticas: Un Marco de Referencia y un Ejemplo

Abstract: Mathematical education as a scientific discipline faces mathematics from diverse educational contexts. In the particular case of a classroom, one of its working objects is the study of strategies for mathematics teaching and learning. This paper presents some elements leading to think about the modeling process as a teaching strategy to tackle the construction of mathematical concepts in the classroom. Such elements become a progress of the research project called The modeling process in school mathematics developed by the Universidad de Antioquia with the support of ITM's Adult education program.

Big Data: una exploración de investigaciones, tecnologías y casos de aplicación

Abstract: Big Data has become a worldwide trend and although still lacks a scientific or academic consensual concept, every day it portends greater market growth that surrounds and the associated research areas. This paper reports a systematic review of the literature on Big Data considering a state of the art about techniques and technologies associated with Big Data, which include capture, processing, analysis and data visualization. The characteristics, strengths, weaknesses and opportunities for some applications and Big Data models that include support mainly for modeling, analysis, and data mining are explored. Likewise, some of the future trends for the development of Big Data are introduced by basic aspects, scope, and importance of each one. The methodology used for exploration involves the application of two strategies, the first corresponds to a scientometric analysis and the second corresponds to a categorization of documents through a web tool to support the process of literature review. As results, a summary and conclusions about the subject are generated and possible scenarios arise for research work in the field.

The roles of nanotechnology and internet of nano things in healthcare transformation

Abstract: Healthcare, as a basic human right, did not remain immune to innovative technologies Technological progress has significantly contributed to high-quality, on-time, acceptable and affordable healthcare Since their appearance, nanotechnology and the Internet of Nano Things (IoNT) have continuously affected healthcare and have a tremendous influence on its transformation, contributing to the better outcome The inclusion of nanotechnology in medicine through nanomaterials and nanodevices, known as nanomedicine, has brought numerous benefits in disease prevention, diagnosis, and treatment Going further by connecting nanodevices to the Internet, the IoNT paradigm has been created The inclusion of IoNT concepts in healthcare has resulted in more personalized, timely, and convenient health monitoring and treatment Hence, nanotechnology and the IoNT hold the potential to completely revolutionize healthcare in the 21st Century, creating a system that will enable early disease detection and diagnosis followed by accurate, on-time and effective treatment with significantly reduced healthcare costs This paper presents the roles of nanotechnology and IoNT in medicine and healthcare, and attempts to gain an insight of nanoscale solutions and approaches, highlighting benefits and discussing potential risks and concerns Despite concerns regarding nanotoxicity, privacy and security issues, it is anticipated that nanotechnology and IoNT will show their full potential in medicine and healthcare in the years to come
