Khan Academy: You get what you pay for, right?


          Is anything ever really free? At what cost do you actually pay for things that claim to be “free?” You’ve heard people say, “Freedom isn’t free.” I agree. Nothing is ever really free, and I will attempt to persuade you to see that the Khan Academy isn’t really free either. It can and does come at a very high cost in some instances.

            Khan Academy is a collection of over 3,000 videos available through the Khan Academy website and YouTube. It is a non-profit organization that sets out with the mission, “to provide a ‘free world-class education to anyone anywhere.’” (Wikipedia) Mr. Salman Khan is the mastermind and creator of the website. He started it in 2006. The Khan Academy has received significant funding from the Bill and Melissa Gates Foundation and Google. (Wikipedia) Khan has even been coined, “Bill Gates’ favorite teacher.” (Kaplan) However, Mr. Khan has received no “formal training as a teacher.” (Stimpson, p. 49)

            According to numerous sources, Khan started tutoring one of his cousins in math and was very successful at helping her improve her math scores. As a result, other family members requested his help, and that is the very meager beginning of what has grown into a very popular education site that is viewed by millions.

            The popular site not only contains videos, but there are also pretests, practice problems, and badges to earn as you progress in your learning. There is a special section that is dedicated to teachers, or “Coaches” as the site refers to them. There are many tools and resources to help the teacher gain knowledge about the needs of her students.

The Khan Academy offers lessons in a variety of subject areas ranging from mathematics to history.  The lessons are offered to the user in a “self-paced” way. Kahn Academy lists the “bedrock principles” behind these lessons as:
Mastery-based to build a strong foundation

Personalized to meet the unique needs of each student

Interactive and exploratory to encourage creativity and applied learning

            As part of my research, I took a math pretest and proceeded to do some of the practice problems. I admit that it was fun! Receiving all that positive feedback, racking up “energy points,” getting hints when needed, and having the coordinating videos available all give the learner a very personal, engaging, and rewarding experience. Unfortunately, I did not have the same euphoric experience when I clicked on the history section. This is when my opinion of the site began to go in a different direction, but I’ll save that for later.

            There are many opinions about Khan Academy to be found on the Internet. Most of what I found in the beginning was all negative, but after digging a little deeper, I was able to find some positive opinions of the site.  Most negative opinions that I found were those of educators, and the positive opinions were usually ones of those who, like Khan, appeared to have no formal teacher training. I was beginning to see a pattern in the opinions that I was reading. If I had no formal training or experience as a teacher, I might also view Khan Academy as the answer to the broken education system of our country.

            When searching for opinions of Khan Academy, I found an interesting, anonymously written blog titled the “Assailed Teacher.” The author of the blog informs readers that he has been teaching history in New York City for 12 years in his “About” section. In his post, “Khan Academy: If You Don’t Like It, You Don’tGet It,” the assailed teacher very poignantly expresses the views of what I found to be that of all the educator comments I read. He starts the post with the comments left by a Mr. Peter Berger on one of his previous posts about the Khan Academy. Mr. Berger was obviously a fan of Khan Academy stating,

You say “What innovation does Sal Khan offer in American education besides a pause button?” and, disturbingly, you say that as if it’s a small thing. This shows that you’re missing the point. A pause button is a huge leap in pedagogy. A pause button is world-changing.

The assailed teacher responded to the “pause button” comment in a statement of his own,

The fact that people believe a pause button is an educational innovation says a lot about how they see teaching. Sure, you can pause and rewind a video however many times you want. What do you get? The same thing over and over, repeated in the same way.

            Essentially the assailed teacher is saying that a “pause-button” doesn’t allow for questioning or having the information presented to the student in a different, more meaningful way. He also addresses other flaws of the Khan Academy such as its focus on teaching facts and procedures rather than promoting thought and discussion.  The assailed teacher places Khan Academy in the same group with reformers who have sought to reform education through rote memorization of facts and standardized testing. (Anonymous)

            Despite having many critics, Khan Academy does have its supporters. Bill Gates is probably the most well known. Gates said, "I'd say we've moved about 160 IQ points from the hedge fund category to the teaching-many-people-in-a-leveraged-way category. It was a good day his wife let him quit his job." (Kaplan) John and Ann Doerr are also staunch supporters, having made large donations. John Doerr is a venture capitalist in Silicone Valley. Another supporter is John McCall MacBain who also generously donated to the Khan Academy. MacBain is from Canada and made a lot of money in the publishing industry. (Kaplan) All these people have something in common, they are not educators, and I doubt they have any formal training as educators.

            Does Khan have any supporters that are also educators? Yes, he does. Supporters of Khan might also be practicing a new method of teaching known as the “flipped classroom.” In this method, students take acquisition of knowledge into their own hands at home by watching videos. The teacher is no longer standing in front of the classroom giving a lecture, but instead he has projects and learning opportunities prepared for students once they return with the knowledge they gained at home. What was once considered homework is now done at school. 

Picture of Shelby Harris and students

            Shelby Harris, a teacher from Idaho, uses Khan’s videos in her flipped 7th grade math classroom. Harris says she feels that she is a better teacher now, and that she is teaching the students rather than the standards. She admits it was difficult in the beginning and she had to “redefine” how she saw herself as a teacher. She now sees herself as more of a “sideline coach.” (Cotterell)

In closing, I would like to present my opinions and concerns from the viewpoint of an elementary teacher. Like all things, the Khan Academy has its pros and cons, but I do not believe it is the answer we’re looking for to correct the problems that have been created in the educational system. The Khan Academy, if used properly, could be a great teaching tool, but that’s it. It’s just a tool, like many others that are available to teachers. It is not the magical answer so many claim it to be.

Teachers have to take on the hard task of changing the way they teach. The days of memorizing facts and showing off your memorization skills on bubble-in tests are over and should have never begun, in my opinion. “Learning” presented in that manner is such an injustice to what the human brain is actually capable of. My hope is that Khan Academy is used to its potential by educators, and also that it is not put on a pedestal above the teacher as the answer to our educational woes.

Good teachers are of an irreplaceable value to the schools, students, and communities they serve. I do not see them being replaced by Khan Academy, but rather, I see them becoming even better at what they do through using tools like Khan Academy to meet the changing needs of their students. In my opinion, any attempt to replace these valuable members of society with Khan Academy would come at a detrimental price making Khan Academy the most costly program that ever hit the education system.

"What is a search engine?"



picture that includes the names of popular search engines


The first thing I did when starting this assignment was go to the all-knowing "Google" and type in the question, "What is a search engine?" I got 548,000,000 results in 0.52 seconds! Luckily, I hit gold with the third result listed. Whew!

The ten search engines listed by Paul Gil were as follows and in this order: 

1. Duck Duck Go (Catchy name! I think I'll check this one out!)
2. Ask (Been there, done that.)
3. Bing (Maybe)
4. Yippy (Again, catchy name. I think I'll check it out!)
5. Webopedia (Sorry, Webopedia. Your name isn't enticing enough.) 
6. Yahoo (Ah! Nostalgia! I should repay this one a visit just for old times' sake.) 
7. Dogpile (What? Ok. I'll check it out.)
8. The Internet Archive (The name is long, but the description sounds interesting.) 
9. Mahalo (I'm there!)
10. Google (Of course, it's listed.) 

I now have 6 search engines to research, as instructed. The winners are: 
1. Duck Duck Go
2. Yippy
3. Yahoo
4. Dogpile
5. The Internet Archive
6. Mahalo 

The results:
1. Duck Duck Go gets an A+! It's neat and simplistic. It kind of reminds me of Google, but without the messy, distracting ads. Duck Duck Go also allows you to search anonymously so that you can't be profiled by your searches. I really liked this one and might make it my new search engine! 

2. Yippy started out promising, but ended in disappointment. I liked the option of choosing which device you are using on the homepage, but when searching my own name, Chea Driver, none of the top 30 hits included me. This engine is known for being able to track down "obscure' content. I guess I'm not "obscure" enough to be listed in the top 30. I don't think I would use it again unless I couldn't find what I was looking for elsewhere. 

3. Yahoo, I remember why I moved on! As soon as you open the page, you are bombarded with tons of information which I find very distracting. It's a complete mess, but if you want to check your horoscope, it's the place to go! 

4. Dogpile was the, "fast and efficient choice before Google," according to Gil. He also gave it accolades for providing "cross link results." This engine would probably be most appealing to dog lovers with it's "Go Fetch" search button and cute doggie mascot. I did like the cross link results, but when trying to search my name in the "White Pages" section available on the homepage, I had to include my first and last name, city, and state before it would "Go Fetch." I found that a little irritating. In my opinion, this doggie needs to go back to obedience school. 

5. The Internet Archive sounded very interesting in the description given by Gil. "The Archive has been taking snapshots of the entire World Wide Web for years now, allowing you and me to travel back in time to see what a web page looked like in 1999, or what the news was like around Hurricane Katrina in 2005." The music and history lover in me instantly fell in love with this search engine. On the homepage, the "Live Music Archive" was especially pleasurable. I also liked the "Curator's Choice" feature. I see myself spending more time using this search engine in the future, but I'll probably mainly use it for pleasure. 

6. Mahalo was well organized. In his description, Gil said the site was, "human-powered." Anything with a human element to it in this digital age sounds appealing to me! The layout reminds me of Pinterest. I liked the "How To" feature on the homepage. There were many other options to choose from, but they were presented in an organized way that wasn't overwhelming to the user. When searching my name, the results automatically included videos and images. I liked that feature, as well. I'd be willing to try out this search engine for a while. 

* Wolfram Alpha Hmm.... What's this problem generator? This looks interesting! I love a good challenge! Ugh... Ok, I'll create an account if I must! Awesome! Math problems! 
I really like this search engine. The homepage is color customizable. Giving the user choices is nice and refreshing. There is so much to explore on this site, from the mobile apps to the resources and tools. This site is not for the novice user, but I think it would be worth the effort of familiarizing yourself with. It even has a feature to analyze your Facebook data! I'll definitely be back!

"Hey! That's not fair!"

plagiarism cartoon

Sitting in my desk in Mrs. Martin's 11th grade AP English class, I got my first, and last, real lesson in plagiarism. She was the most feared teacher in high school, and she did a great job of explaining what plagiarism was and what the penalties were. In the days ahead, I proceeded, cautiously, writing my first term paper. I was filled with the fear of plagiarizing, or maybe it was the fear of Mrs. Martin! 

I think very few students actually set out with the intention to plagiarize. Most are either misinformed or just uninformed. As educators, it is our responsibility to teach them what plagiarism is and how to avoid it. It should be a lesson that is taught early and often. 

First and most importantly, students should be taught why we don't want them to plagiarize, and we should instill them with the confidence to use their own words. As an elementary teacher, I think a lot of students aren't confident in their voices and ideas. It was so hard to make 5th graders understand that I truly wanted to hear their thoughts and not someone else's. The majority felt their reports should sound and look exactly like the reference materials they had used. A few students finally did accept that I wasn't expecting them to rewrite the encyclopedia, and I got some really good writing out of those students. 

As for the "why," I think students could very simply be taught why we don't want them to plagiarize through a creative and meaningful lesson. I have heard students say on many occasions, "Hey! That's not fair!" They may not understand the concept of plagiarism fully and completely, but they certainly understand the concept of fairness. An effective way to teach this lesson is by having the students create something, but ask them not to put their names on it. Next, add the name of another classmate to their work and have it on display upon their return to class. I'm sure that will get immediate feedback and start a great discussion about plagiarism!
