This article is a collective response to the 2020 iteration of The Manifesto for Teaching Online. Originally published in 2011 as 20 simple but provocative statements, the aim was, and continues to be, to critically challenge the normalization of education as techno-corporate enterprise and the failure to properly account for digital methods in teaching in Higher Education. The 2020 Manifesto continues in the same critically provocative fashion, and, as the response collected here demonstrates, its publication could not be timelier. Though the Manifesto was written before the Covid-19 pandemic, many of the responses gathered here inevitably reflect on the experiences of moving to digital, distant, online teaching under unprecedented conditions. As these contributions reveal, the challenges were many and varied, ranging from the positive, breakthrough opportunities that digital learning offered to many students, including the disabled, to the problematic, such as poor digital networks and access, and simple digital poverty. Regardless of the nature of each response, taken together, what they show is that The Manifesto for Teaching Online offers welcome insights into and practical advice on how to teach online, and creatively confront the supremacy of face-to-face teaching.
Mexico’s national university (UNAM) is a public mega university with a 46-year history in open education. This article presents an analysis based on the open, online, flexible provision of technology-enhanced higher education (OOFAT) model, developed by Orr and his colleagues (2018). The aim of this analysis was to characterize UNAM’s open and distance education system in terms of openness, flexibility, and its business model, in three distinct time periods. According to this analysis, the system has evolved in all areas, and at present has a content-focused approach in terms of flexibility and openness, which differs from the OOFAT at the center approach that is desired. The study also characterized the UNAM system’s business model as a prospector-like approach, which highlights the possibilities for instilling innovation through the schools that comprise this system. The analysis allowed for mapping the current situation and thus sheds light on defining the steps necessary for creating an integrally open system.
<p>En este artículo se describe la propuesta curricular del Bachillerato Híbrido de la Ciudad de México (BH-CDMX). A partir de la identificación de los grandes problemas que afectan a la CDMX, se propone un mapa curricular interdisciplinario y con base en los postulados del aprendizaje basado en fenómenos. La interdisciplina de cada una de las asignaturas se alinea con un proyecto que explora problemáticas actuales de la Ciudad, con el fin de que los estudiantes desarrollen una actitud ciudadana proactiva a través del constante diseño e implementación de soluciones creativas, viables y escalables.</p>
<p>Este artículo describe el propósito, diseño y modelos<br />educativo, de gestión y tecnológico del Bachillerato en<br />línea Pilares que la Ciudad de México ofrece a través de su<br />Secretaría de Educación, Ciencia, Tecnología e Innovación<br />(SECTEI). El grupo académico del Bachillerato a Distancia<br />de la UNAM estuvo a cargo de la adaptación y<br />actualización de un programa híbrido que había SECTEI le<br />había solicitado en 2017. En ambas fases este programa<br />cubre las funciones de preparación para la educación<br />superior y para el trabajo, y enfatiza la correspondiente a<br />formación ciudadana. Se puntualizan las restricciones de<br />diseño y las soluciones que se incorporaron para lograr un<br />bachillerato completo, actualizado en contenidos y<br />totalmente en línea que puede consultarse enteramente en<br />dispositivos móviles con una buena experiencia de<br />usuario.</p>
-Inhibitors are widely used to prevent corrosion in cooling-water systems, and their protective performance can be enhanced by combination. The aim of this paper is to identify possible synergistic effects between four low toxicity substances used as corrosion inhibitors for mild steel in industrial cooling-water systems. Electrochemical measurements were obtained following a design of experiments (DOE) where the independent variables were the inhibitors concentrations and the response variable the charge transfer resistance estimated from impedance diagrams. Potentiodynamic polarization curves show that all of them act as anodic corrosion inhibitors. Among the tested formulations, only the interaction between sodium molybdate and sodium tungstate showed statistically significant effects, indicating that they can perform better when used together. The results of this work show the importance of using a statistical tool when designing inhibitor mixtures.
<p><span>En esta entrevista el Profesor Stephen Downes identifica algunas características del conectivismo y de las personas que lo adoptan. Señala que una persona conectivista se caracteriza por ciertos valores: la autonomía (tomar decisiones por uno mismo), la diversidad (complementar las perspectivas con las de otros para tener un panorama más amplio), la apertura (compartir procesos de pensamiento, solución de problemas y creación) y la interactividad (comprender que las redes logran más de lo que los individuos pueden alcanzar).</span></p>
<p>A nueve años de su aprobación, se realizó un diagnóstico de los materiales en línea del Bachillerato a Distancia de la Universidad Nacional Autónoma de México (B@UNAM), para detectar tanto sus fortalezas como áreas de oportunidad. Con base en los resultados, se rediseñó el modelo de desarrollo de materiales, a partir de la filosofía del Büro Ole Schereen, una innovadora firma de arquitectura alemana.</p><p>En este artículo se exponen los lineamientos de construcción de nuestros cursos, enfocados en potenciar el aprendizaje al máximo y generar una experiencia personalizada para el estudiante, que considera sus características específicas.</p>
