This is an old myth from the days of Orientalism. Unfortunately Wikipedia is often edited precisely by people who have simply seen popular accounts by people like Tyson (or Skeptoid podcast, or The New Atlantis) produced with no understanding of the history of science or human thought. The fact is that Ghazzālī nowhere professed that reason or knowledge is ...

The question cannot be answered with a simple 'yes' or 'no', be it about Polish or any other language, as "language difficulty" is not readily definable. For example, there is an effort among linguists to use "language markedness" to predict language difficulty. Jakobson (1941, 1963), however, observed that the marked members of oppositions were ...

Unfortunately, without any conclusive audio of Langan speaking at 6 months we can't really prove whether he could or could not speak. However, it is possible, though unlikely, that he could speak very simple words that early. Such words would depend on fast physical development rather than high IQ, and wouldn't mean he 'learned to speak'. The first step on ...

TLDR version: the jury's still out. There's limited evidence of improvement in narrow tasks, mainly in memory (particularly on stimulants) and in some sub-groups of individuals. There's also a divergence of results on short and long term effects (mostly noted on modafinil)... possibly due to publication bias. Motivation has been offered as a more important ...

Ghazali actually praised the disciplines of math and science saying they are necessary to a prosperous society. Sciences whose knowledge is deemed fard kifayah comprise [all] sciences which are indispensable for the welfare of this world such as: medicine which is necessary for the life of the body, arithmetic for daily transactions and the ...

(I'm a software engineer at Khan Academy.) Today, SRI International released a research report on a two-year study of the use of Khan Academy in schools. We're encouraged by the results. It doesn't cover the use of Khan Academy instead of traditional teaching as your question suggests but instead its use as a supplemental tool. The full report is available ...

The answer to this question is going to depend on definitions - what is an "Average Retention Rate"? Based on how much teaching? etc. To understand the claim, we need to go back to the source. But the source research behind this diagram has been lost in the past fifty years. TEACHING AND LEARNING ACTIVITIES: EXPANDING THE REPERTOIRE TO SUPPORT STUDENT ...

Before I get into detail, I'd like to make a few remarks regarding the questions and their possible pitfalls. First of all, it is not easy to assess how difficult it is for young children to learn a language because they cannot provide you with cognitive feedback until a certain age. That is why "more difficult" lacks a starting point that it can ...

See page 61 of The Design of Future Educational Interfaces : An analysis of matched pairs of problems revealed that when biology students constructed diagrams their scores averaged 36% ... In addition to facilitating hypothesis generation, students' active construction of diagrams and thinking marks was associated with 25–36% higher problem-solution ...

According to this review of studies, children develop a sense of gender quite early and can relate it to themselves early as well: A related question is, when do children recognize their own sex? Infants as young as three to four months of age distinguish between categories of female and male faces [...] By 10 months, infants are able to form stereotypic ...

In some if not most cases, yes. According to this study of motor skills, a greater frequency of feedback can speed up learning of complex tasks until a certain level of expertise is achieved. However in certain context like this study of speech therapy, "immediate or frequent feedback promotes temporary performance enhancement but interferes with retention ...

The talk says that "10,000 hours" is, to within an order of magnitude, the amount of practice required to get expert-level performance: e.g. to be a professional athlete. It says that, conversely, with a bit of practice you can get really good, really quickly. The following is, I think, an example of the truth of that: Those who pass their driving test ...

According to focus@will, the answer is that it depends on the music in question. f@w is a music service claiming to use neuroscience to sequence their music to enhance concentration: f@w has published a white paper[pdf] on their first experiment in 2013, showing a 12% increase in beta and theta frequencies at P3 and P4 when listening to f@w-designed music ...
