"1. The teacher is choosing the technology. It's not always possible, but when you can, let the students choose, and see what happens. Not all of them will be able to. Some need help; so let other students help them. 2. The teacher is choosing the function. This doesn't mean you can't choose the function, but if you students can't control the technology the use nor its function, this can be problematic: the learning is passive from the beginning. 3. The teacher is determining the process. To an extent you have to, but don't overdo it. 4. The technology is distracting. If the technology is more magical than the project, product, collaboration, process, or content itself, try to muffle the bells and whistles. Or use them to your advantage. 5. The technology isn't necessary. You wouldn't use a ruler to teach expository writing, nor would you use a Wendell Berry essay to teach about the Water Cycle. No need for a Khan Academy account and a fully-personalized and potentially self-directed proficiency chart of mathematical concepts just to show a 3 minute video on the number line. 6. The process is too complex. Keep it simple. Fewer moving parts = greater precision. And less to go wrong. 7. Students have access to too much. What materials, models, peer groups, or related content do students actually need? See #6. 8. The teacher is the judge, jury, and executioner. Get out of the way. You're (probably) less interesting than the content, experts, and communities (if you're doing it right). 9. They artificially limiting the scale. Technology connects everything to everything. Use this to the advantage of the students! 10. They're not limiting the scale. However, giving students the keys to the universe with no framework, plan, boundaries or even vague goals is equally problematic. 11. Students access is limited to too little. The opposite of too board a scale is too little-akin to taking students to the ocean to fish but squaring of

"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."

"TimelineJS is an open-source tool that enables anyone to build visually rich, interactive timelines. Beginners can create a timeline using nothing more than a Google spreadsheet, like the one we used for the Timeline above. Experts can use their JSON skills to create custom installations, while keeping TimelineJS's core functionality. "

"Choice Eliminator will eliminate options from a multiple-choice, list, or checkbox type of question. Choice Eliminator is designed for light use only, and may be unreliable when multiple people are taking the form at the same time. Use Dropdown type of questions instead of multiple choice for better reliability. Choice Eliminator will eliminate options from a multiple-choice, dropdown, or checkbox type of question. Great for signing up for time slots or having students choose topics without doubling up. Version 2 uses spreadsheet functions to keep the results up-to-date, besides being more reliable when using limits, this allows you to restore eliminated choices and set the order."

"The Sharing Cart is a block for duplicating course items into a personal library and an easy way to move those Moodle resources and activities between multiple courses on your site. With just three clicks, the Sharing Cart copies and moves a single course item from one course to another. It copies without user data--similar to the "Import" function in Course Administration. From version 2.3, user content in Forums, Wikis, Glossaries and Databases can optionally be included. In addition, items can be collected and saved on the Sharing Cart indefinitely, serving as a library of frequently used course items available for duplication. The Sharing Cart is viewable only by teachers, course creators and administrators."

"En este vídeo en concreto es Oliver Cooke, curador de horología (el «arte y ciencia de medir el tiempo», tampoco en el diccionario) quien explica el funcionamiento básico de los relojes antiguos, esos aparatos de baja tecnología (o alta tecnología para la época, todo depende de cómo se mire), que constan de cinco componentes básicos: energía, ruedas dentadas, mecanismos de escape, controlador e indicador. En este otro vídeo -que es a través de donde descubrí el esta colección- tiene otra estupenda explicación de cómo funcionaba un reloj nocturno datado hacia 1675. Lo cual es toda una curiosidad, porque en aquella época leer la hora por la noche no era trivial: no había luz eléctrica y muchas veces no era fácil acercarse con una vela a un gigantesco reloj de pared."
