The Growth of Knowledge: Crash Course Psychology #18

Spread The Viralist



How does our knowledge grow? It turns out there are some different ideas about that. Schemas, Four-Stage Theory of Cognitive Development, and Vygotsky’s Theory of Scaffolding all play different roles but the basic idea is that children think about things very differently than adults. Hank explains in today’s episode of Crash Course Psychology.

  1. So when a baby laughs during a game of peekaboo it’s not because what you did was funny, it’s because it’s relieved you still exist?

  2. Some people are in the sensonrimotor stage of 'spiritual cognitive development': some "seem to live only in the present; have to see something to know that it exists." They haven't realized that God "exists" though He's out of our sight.
    What stage are you?😊

  3. Would be lovely to see a video on the post-formal stages of adult development. Adult development is a topic that doesn't get talked about much, but I believe has much to offer us. Later stages of development include the growth of consciousness, wisdom, virtue, morality, and generativity. There is a complexity of mind and of understanding that can only come from decades of building perspective.

    I wish for a society in which we balance the drive and vitality of the young, with the wisdom and grace of the elder. In general, elders have life experience that help them become much less self-centered and much more concerned about the well-being of others, as well as of future generations. They have much to offer in a culture that overemphasizes achievement, power, and status and underemphasizes sustainability, altruism, harmony, and service to others.

    See theories by Robert Kegan, Susan Cook-Greuter, Jane Loevinger, Clare Graves, Jean Gebser, Michael Commons, Francis Richards, and much of the research coming out of Harvard on Adult Development and Aging!

  5. Any other teachers of people qualified in education or teaching watching things like these? I find them amazing, and also recognize how they seem to show how everything which seems axiomatic for 'good teaching' is shown to be potentially false. Here a teacher is lecturing, with zero student output and giving a fully teacher-led class. If we did this in our classrooms (in the West at least) we would be told how poor our teaching is. Yet, the content is here, and ran thought in no time at all, yet thousands of students are enjoying it and finding it refreshingly helpful when compared to school. Teacher led instruction does not necessarily lead to student passivity. All the kids in here should be proud of themselves for searching for a better way to learn, and teachers should also learn lessons from the YouTube channels such as this. Although, I would not be too proud of doing this the DAY before an exam lol. Why not watch a video based on what you learnt during the day or the week and review the video after a month. Then you won't need to cram.
