Estudio de la incidencia de una innovación didáctica en el desempeño de alumnos de Física I de carreras de ingeniería en el período 2005-2008.
En el último lustro, el nivel de desarrollo de las competencias cognitivas y comunicativas de los alumnos que ingresan a las carreras de Ingeniería viene experimentando un progresivo descenso que requiere la adopción de medidas para superarlo, por lo que en la asignatura Física I se modificaron las estrategias didácticas que se usaban antes de la implementación de la Ley Federal de Educación, del Ciclo Básico de Ingeniería (CBI) y del Ciclo Común Articulado (CCA). En este trabajo, referimos cómo rediseñamos la práctica docente basándonos en resultados de la investigación educativa en Ciencias y de la psicología del aprendizaje, con el objetivo de ayudar a los estudiantes a desarrollar las competencias mencionadas. De este modo, lograrán ubicar el discurso didáctico en el contexto adecuado y reconocer los nuevos datos que deberán incorporar a su estructura cognitiva, mejorando el desempeño académico. Hacemos un seguimiento y valoración de los resultados obtenidos (período de 4 años), tanto en el plano cognitivo como en el actitudinal, para lo cual efectuamos un estudio comparativo de la respuesta de las diferentes cohortes de ingresantes para evaluar la incidencia de los sucesivos ajustes introducidos, los que se basaron en una evaluación continua de los datos recabados
The Effect of Viticultural Climate on Red and White Wine Typicity - Characterization in Ibero-American grape-growing regions
Aim: This study is part of a CYTED (Ibero-American Program for Science, Technology and Development) project on vitivinicultural zoning. The objective was to characterize the effect of viticultural climate on red and white wine typicity in the macro Ibero-American viticultural region. Methods and results: The climate of 46 grape-growing regions in 6 Ibero-American countries (Argentina, Bolivia, Brazil, Chile, Spain and Portugal) was characterized using the three viticultural climate index of the Geoviticulture MCC System: the Heliothermal index HI, the Cool Night index CI and the Dryness index DI. The main sensory characteristics frequently observed in representative red and white wines of each of these regions were described by enology experts in the respective countries: intensity of colour, aroma, aroma-ripe fruit, body-palate concentration, alcohol, tannins (for red wines) and acidity as well as persistence on the palate. The data were submitted to a correlation analysis of the variables and Principal Component Analysis (PCA). Conclusion: The typicity of red and white wines was correlated with the HI, CI and DI viticultural climate indexes from the MCC System. The main wine sensory variables affected by viticultural climate were identified. Significance and impact of the study : The results can be used to project the potential impacts of climate change on wine sensory characteristics
L'effet du climat viticole sur la typicité des vins blancs: caractérisation au niveau des régions viticoles ibéro-américaines.
There are many studies in the world that characterize the effect of the climate on grape composition and wine characteristics and typicity concerning different viticultural regions. However, the same is not true concerning studies in a worldwide scale to characterize this effect considering different climate types. This study is part of a CYTED (Ibero-American Program for Science, Technology and Development) project in vitivinicultural zoning. The objective was to characterize the effect of the viticultural climate on white wine typicity on the macro Ibero-American viticultural region. The methodology used 46 grape-growing regions in 6 Ibero-American countries: Argentina, Bolivia, Brazil, Chile, Portugal and Spain. The viticultural climate of each region was characterized by the 3 viticultural climate index of the Geoviticulture MCC System (1): HI (Heliothermal index), CI (Cool night index) and DI (Dryness index). The main sensory characteristics observed frequently in representative white wines produced with grapes of each of these 46 grape-growing regions were described by enologists in the respective countries, using the methodology of Zanus & Tonietto (2). The sensory description concerned the intensity of perception of Color (Cou), Aroma - Intensity (Ar), Aroma - Ripe Fruit (Ar-Fm), Body ? Palate Concentration (Con), Alcohol (Al) and Acidity (Ac). The Persistence in Mouth (Per) was also evaluated. The data were submitted to a correlation analysis of the variables and to a Principal Component Analysis (PCA). The results showed that the typicity of the white wines was correlated with the viticultural climate indexes HI, CI and DI from MCC System. The main wine sensory variables affected by viticultural climate are identified
