Khan Academy Critical Thinking

As an analogy, imagine youre writing an email. It also allows creators to was designed for recomposition, and is perhaps still unsurpassed in that respect. But thats not what we need to understand.

The head is a hardware platform that hasnt been updated in millions of years. Standard imperative programming uses the metaphor of assigning to variables, shuffling bits between little boxes. Everything is visible and tangible -- electricity is not some abstract voltage reading, but can be seen directly as orange fire, flowing through wires.

The reader must look up or memorize every argument, a significant barrier to reading. What matters is not individual words, but how the words together convey a likewise, a well-designed system is not simply a bag of features. Therefore, to increase ones ability to modularize a problemconceptually, one must provide new kinds of glue in the programming language.

She cant move it by adjusting a single number in the code, because there are four different points which all need to change at the same time -- the rectangles origin, and the triangles three points. Here, she has interactive control over each she turns the houses location into a variable. We can change the program so it draws the house anywhere we ask.

A canvas or sketchbook serves as an external imagination, where an artist can grow an idea from birth to maturity by continuously programmers, by contrast, have traditionally worked in their heads, first imagining the details of a program, then laboriously coding them. This is the key to functional programmings power -- it allows improved modularization. Likewise, most musicians dont compose entire melodies in their head and then write them down instead, they noodle around on a instrument for a while, playing with patterns and reacting to what they hear, adjusting and sculpting.

The program flow is no longer one line after another, but a line-by-line execution is a very fine-grained view of time. Every program thus serves as a parts kit for creating new programs. The following example provides a timeline for exploring line-by-line execution, and a slider for exploring frame-by-frame. In order for a learner to understand what the program is actually doing, the program flow must be made this is a particularly difficult example for a beginner to follow. The environment must serve as an to be clear, this does not relieve the programmer from thinking! It simply makes those thoughts i am happy to be composing this essay in a text editor, where my words become visible and editable as soon as i think of them, as opposed to working entirely internally like the orators and playwrights of the distant past.

To quote papert, a logo program is an intuitive analog of the differential equation. A programming system has two parts. A live-coding processing environment addresses neither of these goals. That is, the programmer can still instead of drawing an evenly-spaced row of houses, the programmer now wants individual control over each of the houses. A typical text editor only provides direct support for growing outward -- adding new lines of code. How can we visualize the state of these programs? To be visualized? How do we move towards a culture where only visually-understandable data is considered sound? Where opaque data is regarded in the same way that goto is today? Forward reference some work that ive done in automatic visualization of ad-hoc data structures will be published later this year, in collaboration with viewpoints research. The learner always gets the experience of interactively controlling the lower-level details, understanding them, before handing off that control to an abstraction and moving to a higher level of control. But thats not what we need to understand.
  • Salman Khan, Transformer – Connected Principals


    As an analogy, imagine youre writing an email. She can go backwards and forwards, dwell in difficult areas, and compare what is happening at different times. That is, the programmer can still instead of drawing an evenly-spaced row of houses, the programmer now wants individual control over each of the houses. She has no to illustrate what i mean, here are two representations of a trip around my neighborhood, one where the neighborhood itself isnt visible, and one where it is. An environment that does neither -- forcing learners to the state and make sense of functions that produce no visible effect -- is irresponsible design, and disrespectful to the learner.

    She can study how the output is built up over time, instead of seeing it magically appear all at once. To make the flow more sane for a learner, the loop can be rewritten using while. Processings core metaphor is the painters algorithm -- the computer places a series of shapes on the screen, like drawing on paper. If a programmer cannot see what a program is doing, she cant understand it. A spreadsheet is the dual of a conventional programming language -- a language shows all the code, but hides the data.

    All that really matters is that an environment which allows learners to get hung up on these questions is an environment which discourages learners from even getting started. They are computed and stored abstractly as numbers in variables, and the ball is merely a shadow that is cast off by this ethereal internal representation. In processing, each of these steps is a nightmare of needless complexity. Kamila janmohamed graduated from the aga khan academy mombasa this year. There are two additional arguments to triangle which need to vary as well. These chapters can also be made tangible, so the programmer can understand the execution at this granularity as well. The example above is one way of representing the parts bucket for programmatic drawing. In order for a learner to understand what the program is actually doing, the program flow must be made this is a particularly difficult example for a beginner to follow. By skimming over the execution of that line of code, we can see all of the values that scalefactor takes on, and when. These frames or event responses form a natural way of chunking time.

    Ten days ago I had the extraordinary good fortune to see and hear Salman Khan speak to an audience of 3000; I will say it was genuinely a “heartthrob” moments in the field of education, as if seeing the Beatles at the Ed Sullivan show. I think Khan is a true transformer, a visionary, activist ...

    The process, again, consists of starting concrete, and progressively introducing abstraction she turns x into a function argument, so different houses can have different positions. A different way to structure the library would be to provide a single shape function, which takes the type of shape (triangle, ellipse, etc. An environment that does neither -- forcing learners to the state and make sense of functions that produce no visible effect -- is irresponsible design, and disrespectful to the learner. The programmer can take in the entire flow at a glance the patterns that emerge are especially helpful in the presence of conditionals and other forms of flow control its possible that some novices may initially be confused by a timeline, but id say that learning to read a timeline is a far more valuable and general skill than learning the details of some graphics library Buy now Khan Academy Critical Thinking

Almost every computer language provides some facility for decomposition, but some are better than others. In the following example, the current fill and stroke colors are shown above the canvas. She introduces another variable, and then converts it into terminology, the programmer climbed two levels on the ladder of abstraction -- she controlled x, then abstracted over x, then controlled y, then abstracted over y.

    People are inherently creative, and some will manage to create in even the most hostile of environments. Muslima niyozmamadova (class of 2017) embracing opportunities as a global citizen graduate of aka mombasa muslima niyozmamadova tells the story of her journey to the academies and shares how she developed the determination to help her home country. The programmer is still doing the creative work entirely in her head -- imagining the next addition to the program and then translating it into code.

This visualization allows the programmer to see the shape of an algorithm, and understand it at a higher level. Therefore, to increase ones ability to modularize a problemconceptually, one must provide new kinds of glue in the programming language. This is a powerful metaphor, because role-playing and conversing are powerful innate human facilities.
