Integração de tecnologia no desenvolvimento profissional de professores de inglês

This paper deals with the intersection of the didactics of English as a ForeignLanguage (efl) and of Technological Pedagogical Content Knowledge (tpack)to guide teachers in the use of some specific tools and how to integrate theminto their lessons. To meet this requirement, the researchers conducted a study to answer the question: How may the implementation of a teacher development program on tpack impact the English teaching and learning of a group of in-service teachers? The researchers collected data through observations, interviews, and before-while-after questionnaires in the implementation of two technology modules. The participants received a 48-hour course in technology during the first and second semester, as well as four follow-up sessions on the tpack these teachers use in practice, associated with the knowledge intersections, namely tck, tck, and tpk. The professional development was organized into four stages and workshops: a) modeling a technology-enhanced activity type; b) integrating a pedagogical model in a lesson; c) developing technical skills through different virtual resources for lesson planning; d) applying tpack to design tasks for teachers’ lesson plans. The results highlighted a positive impact on professional learning for teacher’s development of tpack. They also revealed that teachers learned to consider the possibility of using technology, access issues in their choices, and use of technology for lesson planning.Este documento presenta la intersección entre la didáctica de la enseñanza del inglés como lengua extranjera (efl) y el conocimiento del contenido pedagógico tecnológico (tpack) para guiar a los maestros en el uso de algunas herramientas particulares y su integración en las clases.

Tecnologías no convencionales para la remoción de plomo presente en aguas residuales: una revisión bibliográfica 2010-2019

Objective: The objective of this review article was to carry out a bibliographic inquiry at the level of scientific articles in local, national and international journals in the period from 2010 to 2019, in relation to unconventional technologies (biopolymers, bioremediation, and agroindustrial waste) that they have been used in the removal of lead (Pb), present in synthetic and / or industrial wastewater. Methodology: The research adopted a qualitative, investigative model of exploratory type. The methodological aspects carried out corresponded to the inquiry and choice of scientific articles (for each of the unconventional technologies selected) in the period from 2010 to 2019, based on keywords; subsequently, an analysis of their content was carried out and two matrices performed in Excel were filled out. Results: The bibliographic review carried out allowed us to observe that: firstly, in relation to the unconventional technologies with the greatest tendency in research, used in the removal of lead, agroindustrial residues are found, followed by bioremediation and finally biopolymers, for which they found and selected 19 for the first, 13 for the second, and for the last nine. Similarly, the countries that have carried out and reported research results around the selected unconventional technologies correspond to: China, Colombia, Korea, Egypt, Spain, France, India, Indonesia, Iran, Nigeria, Malaysia, Mexico, Peru, Romania, Serbia, Singapore and Zimbabwe; in contrast, the selected publications are mostly located internationally. Finally, the highest removal percentages of the order of 100% were presented with agroindustrial wastes (for which 24 have been investigated), followed by 98% with bioremediation (where red algae and six strains of bacteria have been investigated) and finally, biopolymers, with 95.32% (where chitosan, starch, keratin, snail shells and feathers, have been investigated). Conclusions: The unconventional technologies with greater tendency in research and application in industrial wastewater matrices, according to the 2010-2019 period, correspond to agroindustrial waste; In the same way, the majority of wastewater in which these types of methods have been applied correspond to the synthetic ones, which leads to exposing that these must begin to be implemented at an industrial level or a pilot, to observe their efficiency in the removal of heavy metals, and particularly lead. Financing: The investigation carried out did not receive funding.Objetivo: El presente artículo de revisión tuvo como objetivo realizar una indagación bibliográfica de artículos científicos en revistas locales, nacionales e internacionales en el periodo de 2010 a 2019, con relación a las tecnologías no convencionales (biopolímeros, biorremediación y residuos agroindustriales) que se han empleado en la remoción de plomo (Pb), presente en aguas residuales sintéticas o industriales. Metodología: La investigación adoptó un modelo investigativo de corte cualitativo, de tipo exploratorio. Los aspectos metodológicos correspondieron a la indagación y elección de artículos científicos (para cada una de las tecnologías no convencionales seleccionadas) del periodo 2010-2019, teniendo como criterio palabras clave; posteriormente, se realizó un análisis de esos contenidos y se diligenciaron dos matrices realizadas en Excel. Resultados: La revisión bibliográfica permitió observar que: en primer lugar, con relación a las tecnologías no convencionales con mayor tendencia en investigación, empleadas en la remoción de plomo, se encuentran los residuos agroindustriales, seguidos por la biorremediación y por último los biopolímeros, para lo cual se hallaron y seleccionaron 19 para el primero, 13 para el segundo y 9 para el último. De igual forma, los países que han reportado resultados investigativos alrededor de las tecnologías no convencionales seleccionadas, corresponden a: China, Colombia, Corea, Egipto, España, Francia, India, Indonesia, Irán, Nigeria, Malasia, México, Perú, Romania, Serbia, Singapur y Zimbabue; en contraste, las publicaciones seleccionadas se encuentran en su gran mayoría ubicadas a nivel internacional. Por último, los porcentajes de remoción más alto del orden del 100 % se presentaron con los residuos agroindustriales (para lo cual se han investigado 24); seguido del 98 %, con la biorremediación (donde se han investigado algas rojas y seis cepas de bacterias), y finalmente, los biopolímeros, con 95,32 % (donde el quitosano, el almidón, la queratina, las conchas de caracol y las plumas, se han investigado). Conclusiones: Las tecnologías no convencionales con mayor tendencia en investigación y aplicación en matrices de aguas residuales industriales, de acuerdo con periodo 2010-2019, corresponden a los residuos agroindustriales; de igual forma, la mayoría de aguas residuales en las que han sido aplicados estos métodos corresponde a las sintéticas, lo que conlleva a exponer que estas deben comenzar a ser implementadas a nivel industrial o un pilotaje, para observar su eficiencia en la remoción de metales pesados, y de forma particular el plomo. Financiamiento: La investigación llevada a cabo no recibió financiación.   &nbsp

Autonomous Learning and English Language Proficiency in a B.Ed. in Languages Program

This paper reports on an ongoing research project on autonomous learning and English language proficiency being conducted in the B.Ed. in Languages Program in a Colombian private university. There were three phases in this study, observation, action and reflection. Preliminary findings in phase one identified the following traits: low proficiency in English, learners' dependency on teachers, and lack of resources for independence work. Based on these results an action plan was designed. Phase two consisted of the implementation of five stages of a model of autonomous learning. In the third phase it is expected that results will show the ways in which autonomy and language proficiency interact

Analysis of the pedagogical components of 24 significant experiences in sports interest centers in Bogotá, Colombia

The regulatory framework of Bogotá proposes an education that will combine academic excellence and holistic training, which will ensure better, well-being, opportunities, and quality of life for individuals, families, and groups [1]. One of the strategies used for this purpose was called Sports Interest Centers (SIC), an extracurricular space in which Bogotá public school students could select a sport to practice. The objective of this study is to recognize, integrate, re-order and express the pedagogical elements that compose the educational dynamics of 24 schools that used this strategy, as participants in the city’s Sports Interest Centers Festival (SICF). A collaborative hermeneutical study was carried out to understand the educational dynamics and consciously develop the description, analysis, and interpretation of the component elements of a system of pedagogical and didactic actions and their relationships, through school sports. The results demonstrate different emerging pedagogical categories geared at the acquisition of essential knowledge for good living and therefore implicating methodologies that favor the body, displace the mechanical gaze of sports, and bring their transcendence and complexity to school life

Using Coffee Pulp as Bioadsorbent for the Removal of Manganese (Mn (II)) from Synthetic Wastewater

This research focuses on the removal of contaminants from wastewaters as a matter of great interest in the field of water pollution. The first decades of the 21st century have brought numerous approaches for the development of cheaper and more effective adsorbents capable of eliminating heavy metals. The study aims to examine the way coffee pulp (Castilla variety from Caldas, Colombia) was used as a bioadsorbent for the removal of Mn (II) from synthetic wastewater to fulfill goals 3 and 6 proposed in the Sustainable Development Goals stated for the 2030 Agenda, particularly in Sections 3.9 and 6.9. In order to achieve this objective, the agricultural residue was subjected to bromatological characterization, determination of the lignocellulosic composition, and identification of characteristic organic functional groups through IR spectrophotometry, using the ATR (attenuated total reflection) technique. Additionally, the optimal parameters for contaminant removal were identified, regarding the biomass quantity, the optimum pH, the stirring time, the adsorption kinetics, the zero charge potential (pHpzc), the adsorption isotherms, and the explanation of the possible adsorption mechanisms between the contaminant, the surface of the coffee pulp, and the capacity of maximum adsorption. The results show that lignocellulosic material presented a cellulose content of 29.93 ± 0.21% and a lignin content of 19.25 ± 0.16%. The optimum parameters found were as follows: Particle size of 180 µm, contact time from 90 min to 100 RPM, optimum pH of 4.0 pH units, room temperature; the kinetic model adjusted to the bioadsorption process was Ho and McKay’s pseudo-second-order, under an isotherm of the Langmuir model, for which the removal presented was 53.40%, with a maximum adsorption capacity of 8.01 mg·g−1. Finally, the novelty of the reported research consists of using coffee pulp as a bioadsorbent without chemical modification, for the removal of heavy metals, in this case Mn (II), in industrial wastewater, which would be another application of this coffee by-product

Desorption of Coffee Pulp Used as an Adsorbent Material for Cr(III and VI) Ions in Synthetic Wastewater: A Preliminary Study

Some of the diverse agro-industrial waste generated in primary or secondary stages have proved to be promising biomaterials for treating aqueous effluents contaminated, in this case, with heavy metals. Therefore, it is necessary to know their optimal operating conditions and the regeneration or reusability of the solid by-product, an aspect related to desorption. Considering the above, this article presents the findings of a preliminary study related to the desorption process of coffee pulp without physicochemical modification (Castilla variety), an agricultural waste used as a sorbent of Cr(III and VI) ions in synthetic wastewater. The desorption efficiency of four eluting agents at defined concentrations (0.10M)—HC1, HNO3, H2SO4, and EDTA—was evaluated in a time interval of 1 to 9 days. Likewise, the proposals for the sorption and/or desorption mechanisms proposed and reported in the literature with respect to the use of biosorbents derived from the coffee crop are presented. With respect to the results, the coffee pulp used in previous studies of the adsorption of chromium species mentioned (optimal conditions in synthetic water of particle size 180 μm, dose 20 g·L−1, agitation 100 RPM, room temperature, time of 90 to 105 min) showed efficiencies in the removal of Cr(III) and Cr(VI) of 93.26% and 74.80%, respectively. Regarding the extracting substances used, H2SO4 0.10 M was the one that presented the highest desorption percentage in both chromic species, with a desorption of 45.75% Cr(VI) and 66.84% Cr(III) in periods of 5 and 9 days, respectively, with agitation of 100 RPM and room temperature. Finally, the dissemination of preliminary results on the desorption of coffee pulp contaminated with chromic species without physicochemical modification is novel in this study, as similar work with this specific material has not yet been reported in the literature. On the other hand, the limitations of the study and future research are related to the evaluation at different concentrations and of other extractor solutions that allow improving the efficiency of desorption of these chemical species in a shorter time from the coffee pulp (with and without modification) as well as the reuse cycles. As a result, the desorption of coffee pulp used as an adsorbent material in real water could help researchers identify the possible interfering factors that affect the process (foreign anions and cations, organic matter, environmental conditions, among others)
