El Aprendizaje segn el Constructivismo El constructivismo ve el aprendizaje como un proceso en el cual el estudiante construye activamente nuevas ideas o conceptos basados en conocimientos presentes y pasados. En otras palabras, el aprendizaje se forma construyendo nuestros propios conocimientos desde nuestras propias experiencias (Ormrod, 2003). Esta colaboracin tambin se conoce como proceso social de construccin del conocimiento. Algunos de los beneficios de este proceso social son: Los estudiantes pueden trabajar para clarificar y para ordenar sus ideas y tambin pueden contar sus conclusiones a otros estudiantes. Eso les da oportunidades de elaborar lo que aprendieron. Los tericos cognitivos como Jean Piaget y David Ausubel, entre otros, plantearon que aprender era la consecuencia de desequilibrios en la comprensin de un estudiante y que el ambiente tena una importancia fundamental en este proceso. El constructivismo en s mismo tiene muchas variaciones, tales como aprendizaje gene rativo, aprendizaje cognoscitivo, aprendizaje basado en proRevista de Artes y Humanidades UNICA 127 LAS TIC COMO RECURSOS PARA UN APRENDIZAJE CONSTRUCTIVISTA blemas, aprendizaje por descubrimiento, aprendizaje contextualizado y construccin del conocimiento. Independientemente de estas variaciones, el constructivismo promueve la exploracin libre de un estudiante dentro de un marco o de una estructura dada, misma estructura que puede ser de un nivel sencillo hasta un nivel ms complejo, en el cual es conveniente que los estudiantes desarrollen actividades centradas en sus habilidades, as pueden consolidar sus aprendizajes adecuadamente. La formalizacin de la teora del constructivismo se atribuye generalmente a Jean Piaget, que articul los mecanismos por los cuales el conocimiento es interiorizado por el que aprende. Piaget sugiri que a travs de procesos de acomodacin y asimilacin, los individuos construyen nuevos conocimientos a partir de las experiencias.

Silent Spring by Rachel Carson

Silent Spring by Rachel Carson Books’ Argument Life and humans’ ecosystem depend on the environment entirely. The book of Rachel Carson, which is titled as â€Å"Silent Spring†, has shed light on what environmental conservation entails. This book describes the threats faced by the environment due to human activities. It is interested in environmental conservation and the threats of its degradation to nature where it elaborates the details concerning environmental conditions.Advertising We will write a custom essay sample on â€Å"Silent Spring† by Rachel Carson specifically for you for only $16.05 $11/page Learn More In perspective, the author inspects the areas of the environment that have been affected adversely which include the earth’s water sources and atmosphere among others. In this light, she argues that the human race has to pay because of misusing the environment and encourages humanity to conserve it properly. Furthermore, she identifies and c riticizes the strategies that are applied without considering the environmental conservation and protection. In this regard, she describes the effects of using DDT when showing how people have neglected other creatures in the ecosystem. This book has assessed most aspects including the positive and the vast negative impacts of human activities on the environment. The explicit details of societal participation in environmental pollution have pointed out clearly about the effects of human activities and their impacts on the surrounding. She argues that the environment depends entirely on the activities of human beings. Rachel establishes the impacts of man’s socio-economic activities on the environment and the society. Social Factors Several social factors have been outlined in the book as the possible causes of environmental degradation. These factors include overcrowding that arises in the refugee camps. The strategies initiated to save refugees’ lives have resulted to pollution of rivers and other water sources. For instance, the government launches plans to boost food production through irrigation projects which use pesticides. Unfortunately, these actions have led to adverse reactions including the pollution of rivers among others. In this light, a refugee manager attributed the death of birds to pesticide accumulation in the rivers due to the agricultural practices (Rachel, 45). These depict how the human population causes environmental degradation. In malaria prevalent areas, the pesticides used to control mosquitoes have led to a decline in the insects’ population due to the use of DDT. Moreover, Carson also identifies poverty as a major player in the degradation of the environment. The insect disease vectors that carry malaria are very common in places with poor sanitation which arise due to poor social setup and economic imbalances.Advertising Looking for essay on environmental studies?

The pollution of the environment by the pesticides drained into rivers has led to the loss of biodiversity owing to the fact that birds inhabiting the rivers are reported dead. The other result of degradation is the reduced aesthetic value of the environment. The author has brought up a clear incident on how trees are drying due to the use of pesticides. In areas prone to environmental degradation, reduced fecundity, malnutrition, and pandemic diseases have resulted to a negative change of the human population. There are diseases that reduce human lifespan and cause many deaths. The incident elaborated by Carson about two boys who died in Florida is a clear illustration on how death arises from the wastes that people dispose carelessly in the environment (Rachel, 28). Therefore, â€Å"Silent Spring† is the liter ature that most environmental scientists appreciate as it evaluates most issues concerning; the social causes of environmental degradation, its impacts in the societies, and its effects on the environment as a whole.

The coursework focuses on the Airbus Industrie (Airbus), the civil Essay

The coursework focuses on the Airbus Industrie (Airbus), the civil aircraft manufacturer, jointly owned by BAe plc, and French, German and Spanish interest (t - Essay Example Airbus required an overall cost-cutting plan for travel management, an important target being to reduce the travel budget by at least 10%. To achieve that, Airbus decided to implement some new steps. Commercial jet aircraft is universally dependent on long-standing trends in airline passenger traffic. And this tendency can be explained by factors such as financial growth in developed and up-and-coming markets, political stability, profitability of the airline industry, and the globalization and consolidation of the industry. Other important factors are restrictions in air transport communications such as government and environmental regulations and air traffic control. Finally product development strategy and overall competition between manufacturers also impact the market. The industry is very demanding; it requires a long time to regain investments portrayed by long development cycles. It also requires a large base of skilled and experienced workers, high tech supporting industries and sophisticated and serious customers to flourish. Government involvement also plays a major role in determining the industry forces in various countries' industrial strategies and international t rade associations. Airbus strategies internationally operate in an environment shaped by three forces: the industrial constrictions of building modern aircraft, the demands of world and regional markets, and the configuration and objectives of the consortium itself. These factors map onto an integrated strategy analysis. The positional analysis for Airbus must focus on its status as the challenger to the dominant firm, on the consortium's peculiar organizational structure, and on the opportunities and constraints offered by its non-market context. One way of looking at Airbus's experience is as a continual series of disruptions aimed at creating openings for Airbus to enter markets dominated by well-established competitors, in particular, Boeing. These strategic moves have involved both market and non-market elements. The following lines summarize and assess the market and non-market key competitive strategies that Airbus industrie has engaged to establish itself in the crucial world market. 1. Widespread aircraft portfolio to assure the requirements of customer airlines across the board. Boeing is the best positioned with aircraft capacity ranging from 100 passengers (737-500) to 500 (747-400). Airbus had entered the market with small and medium sized carriers, but is fast catching up with the introduction of its four engine long haul A340 aircraft. 2. Pushing high technology, electronic fly by wire systems in order to reduce the number of pilots required-from three to two-and establish re-assigning easily from one type of plane to another, thus curtailing training time by developing the family concept. As an example, Airbus succeeded in achieving authorization from the FAA to have a single pool of pilots to operate its A320, A330 and A340 models. 3. Emerging resolution to pick up cost effective management of their planes, such as the general trend in migration to twin engine wide body planes, providing fuel efficiencies and quick reconfiguration of seating
