Would you know how to change the double push – button discharge mechanism of your house’s cistern?\u00a0How to prepare an apple pie?\u00a0And how to make a French braid?\u00a0Surely you have answered no to any of these questions, but I am sure you would know where to consult to learn how to perform these tasks.\u00a0“How to do …” searches on YouTube\u00a0continue to grow 70% each year<\/a>\u00a0.<\/p>\n 70% of\u00a0millennials<\/em>\u00a0(people born in the last two decades of the twentieth century) usually use YouTube to learn or deepen their training interests.\u00a0In fact, they prefer triple learning through a\u00a0YouTube video than reading a book<\/a>\u00a0.\u00a0So much so, that 67% say they can find on this platform\u00a0a video of anything they want to learn<\/a>\u00a0.<\/p>\n Phenomena such as David Calle, founder of the educational website\u00a0Unicoos<\/a>\u00a0and finalist of the\u00a0Global Teacher Prize 2017<\/a>\u00a0(international award rewarded with one million dollars, with more than 20,000 nominations), offer some surprising figures.<\/p>\n His YouTube channel has more than 700 videos of Mathematics, Physics and Chemistry and has 1.5 million subscribers.\u00a0In 2015, Unicoos was chosen by Google as the channel with the greatest social impact in Spain.\u00a0Are we facing a real revolution in the educational model or is it a passing trend?<\/p>\n In 2012, the so – called ” post – PC era ” began.\u00a0Since then, there are more mobile devices (phones and tablets) connected to the internet than desktops and laptops.\u00a0Our eyes are exposed to almost 10 hours of screens per day, with a growth rate\u00a0maintained in the last 5 years<\/a>\u00a0, and the mobile phone has become the reference tool par excellence.\u00a0On average, we unlock the phone\u00a0more than 220 times a day<\/a>\u00a0, and this very high use has its repercussion also in the teaching field.<\/p>\n The main characteristic that\u00a0students value<\/a>\u00a0regarding the use of technology is mobility.\u00a0Being able to study anywhere and at any time.\u00a0In addition, the preferred feature of the use of technology in the educational field is the improvement in the quality of the content, compared to other skills such as communication with teachers or classmates or the possible saving of study time.<\/p>\n According to the same source, 94% of students say that the use of technology has facilitated the learning of new concepts.\u00a0The leading platform for consumption of digital content is YouTube, with 87% of students who use it frequently.<\/p>\n The educational one\u00a0is the second category of most consumed video<\/a>\u00a0in Internet (only below videos of humor and comedy).\u00a0Does this consumption correspond to an efficacy of the medium?\u00a0Is there any scientific evidence in this regard?<\/p>\n We know that\u00a0our senses evolved<\/a>\u00a0to work together, with each other.\u00a0For example, in the McGurk effect, vision influences the ear;\u00a0we do not perceive in an isolated way, but the brain integrates multisensory information.\u00a0This has a direct implication that we learn better if we stimulate several senses at once.<\/p>\n These results are not new.\u00a0The\u00a0initial experiments of Mayer<\/a>\u00a0showed that multisensory learning problem solving (narrated text and animations) improves outcomes double that of unisensory equivalent written text and images.<\/p>\n Analogously, in\u00a0his theory of dual coding<\/a>\u00a0, Paivio argued that the use of mental images helps learning.\u00a0The visual information (which we consume by sight) and verbal (auditory) information is processed differently, in different channels.<\/p>\n When both channels are used in parallel, the stimulus is encoded in two ways and is more likely to be remembered later.\u00a0The problem comes when we verbalize information from the visual channel (for example, when we read a text).\u00a0The tracing of letters forms words.\u00a0The brain has to decode this visual information to verbalize the information.<\/p>\n Both channels are occupied in an artificial and learned way (remember the effort that costs us in the first years of life to learn to read and write).\u00a0For this reason, we can not read and listen at the same time (have you tried to have a telephone conversation while reading an email?), Or it requires much more effort (and we enjoy less) to watch movies with subtitles than those whose speech we understand directly without need to read<\/p>\n In\u00a0his complete theory of multimedia learning<\/a>\u00a0, Richard Mayer establishes a decalogue of 12 principles that confirm that people learn in a much deeper way by combining words and images and animations that only with words or graphics independently.\u00a0Thus, the video format is positioned as a natural element of highly effective information transmission.<\/p>\n In this new millennium we have significantly changed our quality standards and consumption habits.\u00a0For example, in the case of cinema, plane changes happen much faster.\u00a0In the middle of the last century, the average duration of each plane oscillated between eight and eleven seconds.\u00a0Nowadays, much shorter ones are edited,\u00a0with an average duration of between two and three seconds<\/a>\u00a0.<\/p>\n In the field of teaching, the standard for teaching content is being set by the best teachers in the world, publishing their classes on the web.\u00a0The student can choose to explain the content to their favorite teacher.<\/p>\n One of the most famous cases is the\u00a0Khan Academy<\/a>\u00a0, founded in 2006 by Salman Khan.\u00a0With more than 4,000 videos that have been viewed more than 1,500 million times, it is the benchmark of global education in primary and secondary education based on instructional videos.\u00a0The founder of the Khan Academy, Salman Khan, aims to “provide a free world – class education for anyone, anywhere”, and received the Princess of Asturias Award for International Cooperation in 2019.<\/p>\n This model of “wise on demand” is creating new teaching paradigms, such as the\u00a0inverted class<\/a>\u00a0, where the content of the lesson is consumed at home and the activity in class is dedicated to what the student can not do autonomously at home.<\/p>\n It is the opposite that is usually done in master classes, where the student is basically a note – taking machine.\u00a0Thus, the most autonomous part of learning is done at home (see teaching videos or reading content in written text), and in the most active part (resolution of exercises, problems or debates between students).<\/p>\n The role of the teacher in this model changes completely, departing from the traditional master class.\u00a0The teacher now accompanies the students in a more individual way, taking into account their motivations and particular needs.\u00a0The teacher becomes a\u00a0coach<\/em>\u00a0.<\/p>\n Although we do not have definitive scientific evidence, some\u00a0surveys conducted<\/a>\u00a0in the Flipped Learning Network to more than 450 professors who use this new methodology result in 2 out of 3 cases increased scores in the evaluation tests and 4 out of 5 said an increase in student motivation.<\/p>\n New focus.\u00a0New Times.\u00a0There is so much to do.\u00a0We are not facing the era of change, but before a change of era.\u00a0And this future, from the classroom, looks wonderful.<\/p>\nAs we have changed<\/strong><\/h4>\n
