Userpage

The user page is one's own profile. One can earn energy points, and every day that Khan Academy is used to accrue points, the daily streak increases by one which is reflected on the user page.

   You can earn energy points, and the total of those energy points will be on the upper right of the profile page.

There are also badges, some of which give energy points and/or require energy points. The most common badges are Meteorite badges. The first badge one earns is usually Makes Perfect or Apprentice Programmer.

Modifying Objects

**Modifying Objects** is a talk-through in the objects lesson. Pamela demonstrates how to modify the existing properties of an object or add additional properties while a program is running.

Once again using Winston as an example, Pamela begins with a defined Object called "winston" , with one of its properties being "age: 19".  She then demonstrates how this can be modified to increase his age, using the various codes below:

```
winston.age = 20; //sets age = 20

winston.age = winston.age + 1; //sets age = its prior value +1

winston.age++; //also sets age = its prior value +1

```

She then goes on to demonstrate how to create a loop that gradually increases Winston's age until it reaches 40, and prints his current age as the loop goes along:

```
while(winston.age <= 40) {
    text("Winston is " + winston.age + " years old", 10, winston.age*20 - 350);
    winston.age++;
}

```

Finally, she demonstrates that it's also possible to add new object properties, in this case modifying the above loop to have Winston get married to Winnefer at age 30 (by defining the property "winston.wife"), and have 2 kids, Winston, Jr. and Winstonia, at age 32 (by definining "winston.twins"):

```
while(winston.age <= 40) {
    text("Winston is " + winston.age + " years old", 10, winston.age*20 - 350);
    winston.age++;
    if (winston.age === 30) {
        winston.wife = "Winnefer";
    }
    if (winston.age === 32) {
        winston.twins = ["Winston, JR", "Winstonia"];
    }
}

```

The Fundamental Theorem of Calculus

**The fundamental theorem of calculus** exercise appears under the Integral calculus Math Mission on Khan Academy. This exercise shows the connection between differential calculus and integral calculus.

## Types of Problems

There are four types of problems in this exercise:

1. *Find the derivative of the integral:*The student is asked to find the derivative of a given integral using the fundamental theorem of calculus.
2. *Find the tangent line from the graph of an defined integral:*The student is asked to find the tangent line in slope-intercept form or point-slope form using the graph of the integral.
3. *Define the integral when it is decreasing/increasing on the interval(s):*The student is asked to define when the integral function is decreasing/increasing without the equation by using the given graph.
4. *Define the integral when it is concave down/concave up:*The student is asked to define when the integral function is concave down/concave up without the equation by using the given graph.

## Strategies

Knowledge of derivative and integral concepts are encouraged to ensure success on this exercise.

1. The fundamental theorem of calculus states: the derivative of the integral of a function is equal to the original equation.

2. When the fundamental theorem of calculus is applied, all the variables of the original function turn into x.

4. The integral is decreasing when the line is below the x-axis and the integral is increasing when the line is above the x-axis.

5. The integral is concave down when the line is decreasing and the integral is concave up when the line is increasing.

## Real-life Applications

1. The fundamental theorem of calculus can be used to find the area under a continuous graph and find the tangent line at any given point of a continuous graph.

Patterns for Scene Management

Scene management is a necessary component of programs with more than 1 scene, such as games. We will critique different design patterns to arrive at a good design pattern for scene management.

All of the codes use the same button object, and are for the same simple game.

### Structureless Antipattern

This antipattern just tries to code the game, conveniently changing the draw function and mouseClicked function when required to go to a new scene. Out of the three, this is the shortest, but the code is harder to understand, and is less intuitive.

The code is available here.

### Khan Academy's Scene management pattern

This pattern is not as bad, and eventually possible to wrap our head around. However, it doesn't highlight the importance of scenes and how mouseClicked, besides draw, should change with the scene.

The code is available here.

### Scene object pattern

This pattern highlights the scenes, and allow each scene to own their own buttons. The Scene object can be extended to incorporate more possibilities. This pattern becomes better when there are more buttons. Out of the three, this is the longest (but not significantly longer), but the code is the most intuitive.

The code is available here.

Dave Gilboa & Neil Blumenthal - Co-Founders & Co-CEOs of Warby Parker

Along with two other men, **Dave Gilboa and Neil Blumenthal** formed Warby-Parker. Dave was taking a plane to a backpacking trip and left his glasses on the plane. He was just about to start grad school and couldn't afford the $700 pricetag for new glasses. He actually spent that first semester doing without - and squinting a lot.

Warby-Parker is about reducing the price of glasses from around $700 to about $95. Interestingly enough, while their video discusses them competing on price, it seems they are located in swanky upscale neighborhoods, as they have a store on the Upper East Side, one of New York City's more upscale sections. They also have a shop in Buckhead, a district in Atlanta, which is another affluent area. Their locations are listed here.

None of the founders are named Warby or Parker. So where did they get their name? From a book, that's where. Dave was wandering around a Jack Kerouac exhibit at the library, and among some old journals and manuscripts noticed the names Warby Pepper and Zagg Parker. He found the names interesting, and chose to name the company with them.

In this video, a guy named Tom that teaches Italian on YouTube, tells us that he is getting his glasses at Warby-Parker.

Scratch Vs Khan Academy

Many consider it a question of which is better. They are both sites that teach programming. However, they are very different. Each has its own purpose.

Scratch is a better site for sound and animation, so one would use it to add animations and photographs to music they composed or perhaps a religious piano piece that one recorded. Also, the Scratch site teaches programming through plain English blocks-not code. It's designed for younger users, primarily 8 to 16 years of age. However, they welcome users of all ages.

Whereas, the Computer Science section of Khan Academy is about learning to code. They prohibit uploading files to JS programs. They do have a library of sounds that a user can incorporate. However, many users do not know about it. Users that do know about it, find that there is not adequate selection for their programming desires. The Khan Academy site itself is not designated as a children's website. This conclusion can be reached by the designation into a child account for users under 13 years of age. Child accounts are restricted from interacting with others on the site. The code with blocks course is designed for ages 8 and up and may be sponsored by code.org which \*IS\* a children's site.

One can also take programs or pieces of programs written on Khan Academy and apply them to a Scratch project, as in here or here.
Python

**Python** is a computer programming language.

Python.org describes it as follows:

> Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python's simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.

Each section is broken into short sub-sections and there are tabs to select text or video. They recommend starting with their HTML course, for those looking to learn coding from the web. Users can also advance to the more complicated sub-sections by passing the quiz.

## Programming Languages

* C++
* CSS
* C#
* HTML
* Java
* JavaScript
* PHP
* Python
* SQL
* Swift

## Style

The style on Sololearn includes a choice between text study and video study. The format involves short bursts of learning followed by a quiz question for understanding. The sections end with quizzes on the entire section the student covered.

## Apps

SoloLearn also has apps for each of their courses for Android and iOS, available on the Google Play Store and the App Store respectively.

The apps allow the downloading of offline assets to enable offline learning. In addition the apps are able to determine when the content has been updated, enabling the user to update the downloaded assets, keeping them up to date with latest learning content.

Videos however require an internet connection and are not downloaded as part of the assets.

Seated Figure

Met curator Yaëlle Biro on humanity in **Seated Figure** by the Djenné peoples of Mali and the Inland Niger Delta region.

This haunting figure huddles with its leg hugged to its chest and its head dropped on its knee. It simultaneously suggests the knotted tension of anxiety and the sublime absorption of deep prayer. Created over 700 years ago, in the Inland Niger Delta region of present-day Mali, this elegant work's intense emotional immediacy blurs the boundaries of time and place. This terracotta sculpture comes from a site called Jenne-jeno, the oldest known city in sub-Saharan Africa. Jenne-jeno flourished in the ninth century C.E., but declined and was abandoned by 1400. Items of cast brass and forged iron, clay vessels, and figures like this one survive. They testify to what scholars contend was a richly varied and highly sophisticated urban society.

A few controlled archaeological digs provide only the vaguest outlines of the original significance of the art of this time and region. Recovered terracotta figures are frequently quite detailed. They include jewelry, clothing, and body ornaments such as the parallel columns of bumps and circles on the back of this work. Sometimes they cover the entire body and seem to represent the pustules of some dreadful illness.

Sculptures like this one may represent ancestors or mythic characters, or might have served as guardians. Here, the figure's shaved head and attitude of introspection resemble mourning customs still practiced by many cultures in sub-Saharan Africa. It is possible that the earlier peoples of the Inland Niger Delta had similar ritual methods to express grief over the death of loved ones.

Tweet

Tweet is a character made by Light Runner.

## Highlights

The original program can no longer be viewed on Khan Academy. It is pictured above. It was not animated. If someone wants the code to Tweet, they can try leaving a message on his wall here, or the wall of the founder of KAOS, she doesn't have Tweet, but she does have the code for an un-released Spin-off, Tweeta, meant to be a female version, recently seen giving Tweet a birthday balloon on his wall on KAOS.

## Notable Spin-offs

The spin-off that garnered the most attentions was the program that asked, "what if Tweet fell over?" and featured tweet upside down, kicking, flapping it's beak with it's eye rolling in a circle.
Renaissance and Reformation

**Renaissance and Reformation** is a sub-topic under World History on Khan Academy.

Wi-Phi (Wireless Philosophy)

**Wi-Phi**'s mission is to introduce people to the practice of philosophy by offering lectures on philosophical issues and critical thinking concepts that are freely available in a form that is entertaining, interesting and accessible to people with no background in the subject. We see this as a part of a larger mission: building our collective capacity to engage in rational thought and discourse.  By providing the toolkit for building better minds in the partner content section, we hope that Wi-Phi plays some small role in realizing that goal.

Plagiarism on Khan Academy: Projects

Due to the plain display of the code for all to see, plagiarism of programs is a bit of a problem on Khan Academy.

The most well known instances of plagiarism around the coding section of Khan Academy probably involve the winking wolf , originally created by Clare for the animal attack project. It is pictured here to the right.

Another area where there are a lot of plagiarisms is the "Build-a-House" project.

More on Variables

In the **More on Variables** talk through on Khan Academy, Jessica lays the groundwork for teaching animation, by expanding the user's understanding of variables. Not only can a variable be used to move one shape, for example Winston's face, other variables like Winston's eyes and mouth can be tied into another variable. In this manner, multiple shapes can be moved as a unit.

The illustration from the talk through shows this. Originally, coded at the number `200`, `x` replaces the `x` value of the yellow ellipse that makes up Winston's face. His left eye goes from being `150` to `x - 50`, as `x` is storing `200` to start and the left eye needs to start at the `150` position on the `x` marker. Though Jessica doesn't mention this, a user could use this strategy with the `y` position to make Winston move up and down.

Nova Labs

What do you get when you combine science-based games and research activities with the most popular science series on American television? You get NOVA Labs, a free digital platform where anyone can actively participate in science. Predict solar storms, design renewable energy systems, track cloud movements, design biomolecules and more. Watch our videos, then visit the NOVA Labs website to see how you can take part in real-world investigations by visualizing, analyzing, and playing with the same data that scientists use.

Read more about this here. ***THIS COURSE HAS BEEN RETIRED. Khan Academy is no longer maintaining or updating this course while they focus their limited resources on other courses.***

The Nova Labs section in the Partner Content section of Khan Academy has material that is very easily understandable. While the same material would often put the content to a post high school crowd, the short videos (2 to 6 minutes) with clear content and great graphics makes this partner content great for middle school and up. Even an above average elementary schooler would probably find this section interesting and enjoyable. This is a section that is truly for all ages. They cover variety like evolution, cybersecurity, RNA, Sun/solar system, energy and clouds.

There are also quizzes, which are very easy to get all right if students watched the videos. Speed and accuracy badges are easy to get here, it'd be a waste to not get them. If you've ever heard of the "Sun 101" hack, a quiz in this section used to be hacked. Late fall/early winter 2015, Khan Academy rearranged the content to combine these 1 question quizzes into one larger quiz, thus making the item going around useless, but maintaining the content.

* Evolution
* Cybersecurity
* RNA: the wonder molecule
* The Sun and solar storms
* Energy
* Clouds

School Yourself

**School Yourself** is an online learning site used to study math. On School Yourself, videos and the problem sets are weaved together. The creators of the site came to understand that, for each problem, there's a typical way many students might reach an incorrect answer. So, they incorporated that into their layout, so that if a student gets a problem wrong in the way others often do, there are instructions for that. Students who get a problem right won't see those sides steps meant for the students that didn't get the question correct right away. To learn more about, it see here.
Sine and cosine from rotating vector

***Sine and cosine from rotating vector*** is a video in the Circuit Analysis category/AC Circuit Analysis sub-category of Khan Academy's Electrical Engineering course.

One way to generate sine and cosine is to track the motion of a rotating vector.

Impedance

***Impedance*** is a video in the Circuit Analysis category/AC Circuit Analysis sub-category of Khan Academy's Electrical Engineering course.

The ratio of a sinusoidal voltage to a sinusoidal current is called "impedance". This is a generalization of Ohm's Law for resistors. We derive the impedance of a resistor, inductor, and capacitor. The inductor and capacitor impedance includes a term for frequency, so the impedance of these components depends on frequency.

Programming Projects

## Project Evaluations

Users may do project evaluations, and also submit projects for evaluation. The review criteria for each project varies. The final criterion always being whether or not the project is original work. To evaluate projects, users must first finish at least one programming challenge.

There are also three badges associated with evaluating projects, Evaluator, Astute Analyzer, and Rave Reviewer.

## Project Points

Each project gets 2100 points when passing evaluation, as seen in the attached picture.

## Honor Code

Projects on Khan Academy close with an honor code

```
      I certify that this is all my original work.
      If I took any parts from elsewhere, then they
      were non-essential parts of the project, and
      they are clearly attributed at the top. I will
      show I agree to this honor code by typing "Yes":
