Authors: Romero Chacón Dr. Ángel , Aguilar Mosquera Mtro. Yirsen , Stella Mejía Dra. Luz 
Published: September 2018

Se presentan algunos fundamentos y resultados de la investigación titulada "La experimentación y los procesos de formación de profesores de ciencias naturales", desarrollada por el Grupo de Estudios Culturales sobre las Ciencias y su Enseñanza de la Universidad de Antioquia, Medellín, Colombia. La investigación tuvo como propósito fundamentar una propuesta de formación de profesores de física, que aborde la experimentación en estrecha relación con reflexiones surgidas de la Naturaleza de las ciencias. Se adelantó tanto un análisis documental como un estudio de caso de tipo cualitativo–interpretativo, de los enunciados de un grupo de profesores de física a propósito de temáticas relacionadas con la experimentación. Los análisis adelantados permitieron caracterizar formas de asumir el rol de la experimentación en la clase de ciencias, que sirvieron de base para diseñar una propuesta de enseñanza de las ciencias en torno a la experimentación, dirigida a la formación de profesores de física y contextualizada con aportes de la Naturaleza de las ciencias. AbstractSome foundations and results of the research entitled "The experimentation and training processes of science teachers", developed by the Group Estudios Culturales sobre las Ciencias y su Enseñanza at the University of Antioquia, Medellín, Colombia, are presented. The research was aimed to support a physics teacher training proposal, addressing experimentation and closely with reflections that comes from the Nature of Science. A documentary analysis was developed both as a case study of qualitative–interpretative type of statements of a group of physics teachers about issues related to experimentation. The developed analyzes allowed to characterize ways to assume the role of experimentation in science class, which formed the basis for designing a proposal for science teaching around experimentation, aimed at physics teacher training and contextualized with contributions from the Nature of Science.

Comparación de la implementación de una propuesta didáctica diseñada por dos profesores
Authors: Tarazona Vargas Mtra. Liliana , Candela Dra. Antonia 
Published: September 2018

Este es un estudio etnográfico centrado en el proceso de formación continua de dos profesores en uno de los seminarios de la maestría que cursan. Nuestro propósito es analizar cómo participan los profesores en una propuesta de formación en enseñanza de ciencias basada en la práctica docente cotidiana. Es conocida la influencia de los saberes docentes en la manera como ellos ponen en práctica propuestas que otros les aportan. Sin embargo, son escasos los trabajos que analizan cómo implementan propuestas elaboradas por ellos mismos, como se realiza en este artículo. Aquí se encuentra que la implementación de una misma propuesta en los dos grupos de los maestros que la elaboraron conduce a diferentes prácticas. Del análisis de esas diferentes implementaciones se pueden interpretar cuáles son las consideraciones implícitas de los docentes sobre el aprendizaje, la influencia de las diversas condiciones de trabajo y de sus orientaciones didácticas implícitas. AbstractThis is an ethnographic study focused on the process of training in service of two teachers at one seminar of the master degree they study. Our purpose is to analyze the teachers' participation in a training proposal for science teaching based on the everyday teaching practice. The influence of teachers’ everyday knowledge on how they put into practice proposals developed by other specialists is already known. However, there are less researches addressing how teachers implement proposals designed by them, as it is done in this paper. In this research it is shown that different practices result from the implementation, at their groups, of a proposal done by two teachers. Their implicit considerations about learning, the impact of their working conditions and their implicit didactic orientations can be analyzed from the differences in the implementation.

Acercamiento etnográfico a la alfabetización digital en un Instituto de Educación Secundaria Obligatoria en Barcelona
Authors: Martínez Ortega Mtro. Francisco , Subías Lic. Jaume , Cassany Dr. Daniel 
Published: September 2018

En la transición de una promoción de alumnos hacia la Educación Secundaria Obligatoria en un centro adscrito al modelo 1x1 encontramos una estrategia de alfabetización digital. Usando referentes de la didáctica de las lenguas la analizamos para conocer cómo los profesores la conciben, cómo se implementa y qué prácticas letradas digitales están implicadas. A través de un acercamiento etnográfico entrevistamos al profesorado responsable de la planificación e implementación, recopilamos documentos y realizamos observaciones de aula: tomamos notas, fotografías y realizamos grabaciones de audio. Identificamos que en este contexto la alfabetización en el ámbito digital adquiere un carácter metafórico (como conocimientos básicos de herramientas digitales) brindando oportunidades limitadas de participación en prácticas letradas digitales a los alumnos. Encontramos dos procesos relevantes para la alfabetización en el ámbito digital: la selección de prácticas letradas y su transformación en objetos de aprendizaje. AbstractFramed by the transition to secondary education under the One Laptop Per Child model (OLPC) we analyze (using concepts of Didactics of Languages) a school's digital literacy teaching efforts gathered in its Computer Literacy Sessions. We seek to understand: how the task is conceived by teachers, how is implemented, and the digital literacy practices implied. Performing an ethnographic approach we interviewed the teachers who designed said sessions. We also conducted classroom observations where we obtained fieldnotes, photographs, audio recordings and related documents. We identified that the digital literacy is conceived (in a metaphorical sense) as a basic knowledge of digital tools. This brings limited experiences in digital literacy practices to the students. We found two important processes for digital literacy teaching: the selection of digital literacy practices and their transformation into learning objects.

Authors: Olivo Franco Mtro. José Luis 
Published: September 2018

En este artículo se describen los hallazgos de la investigación titulada “Caracterización de estudiantes exitosos: Una aproximación al aprendizaje de las Ciencias Naturales”, resumidos en tres componentes imbricados entre sí: componentes motivacionales intrínsecos, motivacionales extrínsecos, y características y estrategias de aprendizaje. La investigación se desarrolló desde un paradigma interpretativo, bajo el método fenomenológico; empleando técnicas como observación, entrevista a profundidad y grupo focal. Como muestra teórico estructural no estadística se seleccionaron intencionalmente diez estudiantes con rendimientos académicos sobresalientes de la Institución Educativa Técnica Alberto Pumarejo de Malambo, Colombia. Los procesos de categorización y microanálisis permitieron que emergieran no sólo estos tres componentes, sino también comprender la autorregulación como un fenómeno multidimensional y contextualizado, empleado por los estudiantes para tener éxito. Finalmente se prioriza sobre las actuaciones de los docentes en el uso de estrategias creativas y diversas que fomenten y desarrollen actitudes metacognitivas y autorregulatorias en los estudiantes.Characterization of successful students: An approach to the learning of the Natural SciencesAbstractThis article describes the findings of the research entitled “Characterization of successful students: An approach to the learning of the Natural Sciences”, summarized in three components interwoven with each other: intrinsic motivational components, extrinsic motivational, and learning characteristics and strategies. The research was developed from an interpretative paradigm, under the phenomenological method, using techniques such as observation, in-depth interview and focus group. As a non-statistical structural theoretical sample, ten students with outstanding academic performance of the Alberto Pumarejo Technical Educational Institution of Malambo, Colombia were intentionally selected. The processes of categorization and microanalysis allowed to emerge not only these three components, but to understand self-regulation as a multidimensional and contextualized phenomenon, used by students to be successful. Finally, it is prioritized on the actions of teachers in the use of creative and diverse strategies that promote and develop metacognitive and self-regulatory attitudes in students.Recibido: 19 de diciembre de 2016Aceptado: 05 de junio de 2017
DeepSMILES: An Adaptation of SMILES for Use in Machine-Learning of Chemical Structures
Authors: O'Boyle Noel , Dalke Andrew 
Published: September 2018

BackgroundThere has been increasing interest in the use of deep neural networks for de novo design of molecules with desired properties. A common approach is to train a generative model on SMILES strings and then use this to generate SMILES strings for molecules with a desired property. Unfortunately, these SMILES strings are often not syntactically valid due to elements of SMILES syntax that must occur in pairs.ResultsWe describe a SMILES-like syntax called DeepSMILES that addresses two of the main reasons for invalid syntax when using a probabilistic model to generate SMILES strings. The DeepSMILES syntax avoids the problem of unbalanced parentheses by only using close parentheses, where the number of parentheses indicates the branch length. In addition, DeepSMILES avoids the problem of pairing ring closure symbols by using only a single symbol at the ring closing location, where the symbol indicates the ring size. We show that this syntax can be interconverted to/from SMILES with string processing without any loss of information, including stereo configuration.ConclusionWe believe that DeepSMILES will be useful, not just for those using SMILES in deep neural networks, but also for other computational methods that use SMILES as the basis for generating molecular structures such as genetic algorithms.

Published: September 2018

Objective: This study evaluated the radiographic results of the traditional minimally invasive percutaneous Reverdin-Isham surgical technique for hallux valgus treatment using the American Orthopaedic Foot and Ankle Society (AOFAS) score and compared this result with a proposed modification involving additional osteosynthesis with a cannulated screw. Methods: We retrospectively assessed 22 feet across 15 patients with mild to moderate hallux valgus. All patients underwent surgical treatment using the Reverdin-Isham technique. Eleven feet were fixed with 2.4- or 2.7-mm cannulated screws. A single orthopaedic surgeon performed these procedures between January 2014 and June 2016. The metatarsophalangeal (MTP) angle and intermetatarsal angle (IMA) were evaluated using radiographs, and the AOFAS score was applied before surgery and 90 days after. Results: An improvement was found in the parameters evaluated in both groups, with significant differences shown between the pre- and post-procedure follow-up assessment. No significant difference was found between the groups with regard to fixation; however, the scores were slightly higher for the group where osteosynthesis was used. Conclusions: The Reverdin-Isham procedure is effective and safe for correcting mild to moderate hallux valgus and additional fixation presented with promising results, although without significant difference. Additional studies with larger samples and longer follow-up times are needed to define the role that additional screw fixation plays in the overall scope of treatment.Level of Evidence IV; Therapeutic Studies; Case Series.
The Role of Indonesian Constitutional Court In Protecting Energy Security
Authors: Armia Muhammad Siddiq 
Published: September 2018

After more a decade, Indonesian Constitutional Court (ICC) has importantly played a significant role in the law reform, such as protecting energy security through their judgements. ICC comes out of the box, creating unpredictable judgements, and ensuring the justice values. In protecting energy security ICC makes important breakthrough with reviewing Act Number 22 of 2001 on the Oil and Earth Gas, Act Number 4 of 2009 on the Mineral Mining and Coal, and invaliding Act Number 20 of 2002 on the Electrical Power. Those acts contradict the basic norm in the 1945 Constitution. Although creating public debate, ICC judgment should be appreciated.
