Ítem Exploring Undergraduate Students' Computational Modeling Abilities and Conceptual Understanding of Electric Circuits(Institute of Electrical and Electronics Engineers Inc., 2018-08-01) Ortega-Alvarez J.D.; Sanchez W.; Magana A.J.; Universidad EAFIT. Departamento de Ingeniería de Procesos; Desarrollo y Diseño de ProcesosContribution: This paper adds to existing literature on teaching basic concepts of electricity using computer-based instruction; findings suggest that students can develop an accurate understanding of electric circuits when they generate multiple and complementary representations that build toward computational models. Background: Several studies have explored the efficacy of computer-based, multi-representational teaching of electric circuits for novice learners. Existing research has found that instructional use of computational models that move from abstract to concrete representations can foster students' comprehension of electric circuit concepts, but other features of effective instruction using computational models need further investigation. Research Questions: 1) Is there a correlation between students' representational fluency and their ability to reason qualitatively on electric circuits? and 2) Is the quality of student-generated computational representations correlated to their conceptual understanding of electric circuits? Methodology: The study comprised two cases in which 51 sophomore-engineering students completed a voluntary assignment designed to assess their representational fluency and conceptual understanding of electric circuits. Qualitative insights from the first case informed the design of a scoring rubric that served as both the assessment and the data collection instrument. Findings: The results suggest that a multi-representational approach aimed at the construction of computational models can foster conceptual understanding of electric circuits. The number and quality of students' representations showed a positive correlation with their conceptual understanding. In particular, the quality of the computational representations was found to be highly, and significantly, correlated with the correctness of students' answers to qualitative reasoning questions. © 1963-2012 IEEE.Ítem Feminicidio en la prensa : mercado de información y género en Colombia(Universidad EAFIT, 2019) Gómez-Mesa, Sara María; Bonilla Mejía, LeonardoThe media is the main source of information for the public. In fact, they can influence people's perceptions and everyday behaviour. However, are there biases in reporting femicides in the Colombian media? Is it possible that characteristics of the demand for information relate to the news reported in the media? Despite being a crime with high prevalence and great social impact, there are few academic studies that address these questions. This paper analyzes what factors relate to the probability of a femicide being published and its prominence in the Colombian print media. The evidence is based on information about women homicides reported by the Colombian National Police and their news in national media. I analyze whether a femicide was reported and in what amount given individual variables of homicide, victim and municipality of the crime. The results indicate that there is bias in selection according to characteristics of the municipality where the homicide was committed. The characteristics of the victim and the homicide are also influential to the prominence of the crime in the media. In a second stage, I study whether these media decisions vary after shocks on the demand for information. The estimations indicate that biases in the amount of news can be influenced by consumer preferences, while selection cannot. Finally,there are no changes in the total number of daily femicides due to the demand shocks. The results indicate in general a sensationalization of violence in this type of crimes as a result of the demand for information preferences.Ítem Fracking en El Tiempo : ¿contribución a la deliberación democrática? = Fracking in El Tiempo: a contribution to democratic deliberation?(Universidad EAFIT, 2018-12) Vahos Pérez, Andrea; Universidad EAFITThis article deals with the role of the media in its contribution to citizen deliberation. It investigates whether the way in which El Tiempo covered the fracking issue favored public reasoning by offering quality information. To determine this, 51 journalistic contents were analyzed to establish if the media developed the most outstanding and polemic elements about this technique, namely: its economic, environmental and social incidence. In this regard, a relevant finding is the privilege given to certain sources that showed this extraction technique as an economic necessity and opportunity; a fact that generated a significant bias, since the arguments necessary for a reflective debate, such as the environmental and social risks inherent to fracking, were deliberately overshadowedÍtem La sanción social y el fenómeno de la cancelación política en Medellín : un análisis desde la comunicación política(Universidad EAFIT, 2024) Robledo Hernández, María Paulina; Restrepo Echavarría, Néstor JuliánÍtem Personalización de la política en el marco de la pandemia del Covid-19 : el caso de Medellín y Bogotá(Universidad EAFIT, 2020) Giraldo Bedoya, Wilmar; Restrepo Echavarría, Néstor JuliánPersonalization is an inherent feature of politics, and the media have been responsible for this phenomenon being increasingly strong and for it being presented, not only in the election campaign, but also at crucial moments such as a crisis. This study tried to show a specific case of political personalization in the cities of Medellín and Bogotá, within the framework of the pandemic generated by the Coronavirus. All this from an analysis of the media El Colombiano and El Tiempo, evaluating in each one the amount of news that were published in a certain period of time, the number of times that Daniel Quintero and Claudia López were mentioned, the topics with which they related these presidents and the informative tone with which each media published. Similarly, the study recounts the dates and crucial moments of the public agenda that were personalized and how this was promoted from each medium leaving aside the institution that represents each mayor, simplifying each action in his name or his government.Ítem Phenomenology and the ideal of science.
