Brain Drain: The Mere Presence of One's Own Smartphone Reduces Available Cognitive Capa... - 0 views

  •  
    "Our smartphones enable-and encourage-constant connection to information, entertainment, and each other. They put the world at our fingertips, and rarely leave our sides. Although these devices have immense potential to improve welfare, their persistent presence may come at a cognitive cost. In this research, we test the "brain drain" hypothesis that the mere presence of one's own smartphone may occupy limited-capacity cognitive resources, thereby leaving fewer resources available for other tasks and undercutting cognitive performance. Results from two experiments indicate that even when people are successful at maintaining sustained attention-as when avoiding the temptation to check their phones-the mere presence of these devices reduces available cognitive capacity. Moreover, these cognitive costs are highest for those highest in smartphone dependence. We conclude by discussing the practical implications of this smartphone-induced brain drain for consumer decision-making and consumer welfare."

  • B. F. Skinner, referring to the first days of his "teaching machines," in the late 1950s and early 1960s, wrote, "I was soon saying that, with the help of teaching machines and programmed instruction, students could learn twice as much in the same time and with the same effort as in a standard classroom."

  • Computer literacy should be taught as early as possible; otherwise students will be left behind.
  • To make tomorrow's work force competitive in an increasingly high-tech world, learning computer skills must be a priority.
  • Technology programs leverage support from the business community—badly needed today because schools are increasingly starved for funds.

Poverty Impedes Cognitive Function | Science - 0 views

  •  
    "Burden of Poverty Lacking money or time can lead one to make poorer decisions, possibly because poverty imposes a cognitive load that saps attention and reduces effort. Mani et al. (p. 976; see the Perspective by Vohs) gathered evidence from shoppers in a New Jersey mall and from farmers in Tamil Nadu, India. They found that considering a projected financial decision, such as how to pay for a car repair, affects people's performance on unrelated spatial and reasoning tasks. Lower-income individuals performed poorly if the repairs were expensive but did fine if the cost was low, whereas higher-income individuals performed well in both conditions, as if the projected financial burden imposed no cognitive pressure. Similarly, the sugarcane farmers from Tamil Nadu performed these tasks better after harvest than before. Abstract The poor often behave in less capable ways, which can further perpetuate poverty. We hypothesize that poverty directly impedes cognitive function and present two studies that test this hypothesis. First, we experimentally induced thoughts about finances and found that this reduces cognitive performance among poor but not in well-off participants. Second, we examined the cognitive function of farmers over the planting cycle. We found that the same farmer shows diminished cognitive performance before harvest, when poor, as compared with after harvest, when rich. This cannot be explained by differences in time available, nutrition, or work effort. Nor can it be explained with stress: Although farmers do show more stress before harvest, that does not account for diminished cognitive performance. Instead, it appears that poverty itself reduces cognitive capacity. We suggest that this is because poverty-related concerns consume mental resources, leaving less for other tasks. These data provide a previously unexamined perspective and help explain a spectrum of behaviors among the poor. We discuss some implications for poverty policy."

Preguntas que encienden la chispa del aprendizaje: desde Sócrates hasta hoy, ... - 1 views

  •  
    "...Preguntas esenciales Dentro de la gran variedad de formas y objetivos de las preguntas que podemos formular los profesores a los alumnos en el aula, McTighe y Wiggins (2013) han identificado unas que son especialmente importantes para facilitar la comprensión de las ideas y procesos claves en el aprendizaje: las preguntas esenciales. Según los autores, estas preguntas se caracterizan por: Son abiertas. No tienen una respuesta única, final y correcta. Invitan a la reflexión, a menudo generando un debate o discusión. Estimulan el pensamiento de orden superior como el análisis, la inferencia, la evaluación o la predicción. Proponen ideas importantes en disciplinas concretas o que se pueden transferir a otras. Sugieren nuevas preguntas que estimulan una mayor investigación. Requieren apoyo y justificación, no solo una respuesta. Se repiten en el tiempo; es decir, la pregunta debería poder ser planteada en nuevas ocasiones. Estas preguntas esenciales que estimulan la reflexión, la investigación o nuevas preguntas y no solo respuestas adecuadas, sirven como vías de acceso a la comprensión, se centran en el aprendizaje a largo plazo y pueden utilizarse en cualquier materia. Pongamos algunos ejemplos: Historia: ¿Cómo podemos saber lo que realmente ocurrió en el pasado? Matemáticas: ¿Cuándo y por qué deberíamos realizar una aproximación? Lectura: ¿Qué hacen los buenos lectores cuando no entienden un texto? Ciencia. ¿Qué provoca que los objetos se muevan tal como lo hacen? Arte: ¿Qué influye en la expresión creativa? Este tipo de preguntas, junto a las utilizadas en la interrogación elaborativa y la auto-explicación que fomentan la metacognición, serán imprescindibles y acostumbrarán a los alumnos a cuestionarse lo que están haciendo, lo cual les permitirá afrontar mejor los nuevos retos del aprendizaje, y no solo el de la escuela. Como siempre comentamos, en la práctica se requiere flexibilidad.

La nostalgia conductista en la educación me tiene cansada… - 0 views

  •  
    "Aceptémoslo: varios comentarios derivados de supuestos enfoques "cognitivos" del aprendizaje están peligrosamente más cercanos a Skinner y Gagné que a nuevas formas de entender el conocimiento. Y ni hablar de las remembranzas y permanentes menciones nostálgicas que encontramos en la web a la Taxonomía de Bloom!!!!! Y me parece que de una vez por todas deberíamos poner blanco sobre negro. Construir el conocimiento no es lo mismo que recibir información y procesarla. Ideas previas no es lo mismo que estructuras de conocimiento. Expectativas de logro no son lo mismo que competencias. Fijar y predeterminar los aprendizajes esperados no es lo mismo que respetar los tiempos y formas de aprender y menos aún considerar la variedad de estilos de aprender. Un diagnóstico del grupo en términos didácticos no es lo mismo que ver lo que la maestro anterior le enseñó a los chicos. Considerar "las siete inteligencias de Gardner" no es lo mismo que asimilar y acomodar conocimientos. Hablar de comprensión genuina no es lo mismo que referirnos al conflicto cognitivo. No es lo mismo un chico inquieto que tener Déficit de Atención!!!! Y así podría seguir enumerando cantidad de frases y lugares comunes que suelo leer y escuchar, pero me interesa focalizar la mirada sobre aquellas confusiones que hace que el conductismo hoy siga siendo una gran solución en la enseñanza. ..."
