We Want Our M(ath) TV! – Part 3

February 8th, 2011

Welcome to the third part of “We Want Our M(ath)TV!”, all about some of the online video formats, past and present, that people are using to teach one another.  At Knewton, we’ve always thought that online video has tremendous power as an engaging educational tool; recently, we used YouTube to create an interactive, choose-your-own-adventure quiz. Luckily, we’re not alone in seeing video’s potential for engagement – and instructional power.

In our first post, we discussed “First Person Shooters,” where the “teacher” is not visible and the teaching takes center stage. Our second post focused on YouTube e-classrooms: instructional videos featuring teachers speaking directly to the camera.

Today, we’ll talk about math educators who are less content to show their work or to be the sage on the stage, and instead have experimented with different formats for math learning.

We’ve picked a few to showcase below.

Lawrence Perez

Lawrence Perez, a San Diego professor, has created skits between him and his alter ego “Charlie” (something of a cross between Charlie McCarthy and Joe Bloggs), the kid who is always confused.

Lawrence’s videos definitely aren’t for everybody, but for those students who connect with his teaching style, his videos on the MuchoMath Youtube channel are great ways to learn math. Viewers have already requested Perez to make more videos and videos on different subjects. For many students, the MuchoMath instructional videos have proved an efficient and entertaining way to learn.

Alex Kajitani

Alex Kajitani (and countless others) have pioneered the “math rap” genre, which peaked and sharply declined in 2007, but lives on in the long tail of the web. These MathRaps videos may be dated, but they are hilarious, corny and, most importantly, very useful.

GED Academy

Although the GEDAcademy channel videos were created for students who needed help with the GED exam, many students who need help with math in general have found these animated videos a useful alternative to dry math textbooks.

The GEDAcademy videos almost have a “South Park meets French textbook illustration” vibe, don’t they?

It’s heartening to see more and more teachers exploring and embracing math teaching alternatives. By creating accessible online resources for students, teachers are enhancing their ability to connect to potential learners — and providing students with more relevant, exciting ways to learn important math concepts!

Video: Idioms 101

February 8th, 2011

We recently a released a new and improved on-demand video player in our GMAT course, and to spread the word we’re releasing the first Sentence Correction lesson in nine handy installments. If you’re looking improve your score in SC, be sure to watch all the videos for expert advice on this tricky section.

The final installment of the lesson, shown above, is all about idioms. Idioms are constructions that must be worded in a certain way. For many of our GMAT students, idioms are extremely frustrating because there’s no logical explanation for why they are correct or incorrect. It’s just the way it is!

Often, the GMAT tests which certain preposition must be paired with a noun or verb to express the proper meaning. In this video, expert instructors Jen Rugani and Dave Ingber will provide a primer on spotting idiom errors and figuring out the right answer. There’s also a practice problem built into the video; when you get to the practice question, just pause the video, take about 90 seconds to try it out on your own, and then play the video again for a full explanation.

Check out the video for more details, and if you missed any of the previous installments of SC Lesson 1, be sure to check them all out here!

Interning at Knewton After College: An Untraditional, but Rewarding Path

February 7th, 2011

Nina as a jellyfish at Knewton's Halloween celebration

This post was written by Nina Arjarasumpun.

Time flies when you work at a start-up.

College moves pretty quickly, but life in the real world starts so much faster.  Once those commencement caps hit the ground, newly minted alumni are thrown into an unknown realm — even if they’ve already landed a job or a spot in grad school.  Regardless of the state of the economy and personal and financial pressures, some people know exactly where to go next.  Some are content to go wherever they can, even if they know it’s not exactly what they want.  Others are willing to take a chance and enter the world post-graduation without anything yet set in place.

I decided to take a chance. Job offers came in, but nothing felt quite right. Saying no was incredibly hard, especially at a time when many of my peers were willing to say yes to almost anything. People told me I was being picky and impractical, but I wasn’t ready or willing to build momentum on a career path I knew wasn’t the right fit for me.

What did seem like the right fit for me, though, was this marketing internship with Knewton that I learned about during a user experience interview I had with the company right before graduation.  As a proud Knewton GMAT student, I was happy to provide student feedback, but the opportunity to actually intern with them was definitely even more exciting.  Before my imagination went wild about what their office and the people there were like, though, I needed to go in for an interview.

When I arrived at Knewton HQ, I was ushered into a room undergoing renovation. An empty bookshelf served as a makeshift table; we sat on boxes with unassembled chairs inside. Some people might have been turned off by the slapdash furnishings, but I could already sense the buzz of productivity and inspiration in the office. Plus, the job sounded like a great opportunity: it not only matched my interests, but would also give me the chance to find new Knewton students to become as enthusiastic as I was about the company and brand.

I started off learning SEO, doing college outreach, helping out with online customer service, and organizing GMAT study meet-up groups. The days flew by. Diving head-first into a workplace in which so many people are driven to make a difference in how people learn was incredible. The talent and creativity of my colleagues was astounding and a testament to how the company had managed to develop so much in just two short years. I myself was growing and learning at a phenomenal rate. It’s hard for me to believe that I would have gotten such a rich and rewarding experience at a standard entry-level position elsewhere.

The icing on the cake of my last two months here was coordinating the relaunch of Knewton’s entire marketing site in less than 60 days. I was eager for more experience in product development (with the site serving as the product in this scenario), and the fact that the Knewton team allowed me to take on this challenge says a lot about the level of trust they put in their interns. Two months was a crazy timeline in which to launch a website, but it was amazing to see the members of the marketing team step up their game and move out of their comfort zones to not only get the job done — but get the job done well.

Over the past seven months, I have been able to experience and contribute to a lot of the great developments happening at Knewton, and I know that this is only the start of the company’s successes. From day one of learning about Knewton while browsing for GMAT prep courses and really connecting with the vibe of the company, I knew that there was something special about the team. I couldn’t have asked for a better time to be part of the company. Being an intern at Knewton has encouraged me to push myself in ways I never imagined I could so early in my career. The company’s fast-paced, collaborative environment gave me the confidence to take on projects that many other recent grads wouldn’t consider. I for one am glad that I was “picky” and “impractical” and held out for a real-world position that truly felt like the right fit.

How to Save Room on Your Resume: Remove Unneeded Information

February 7th, 2011

MBA resumeThis resume tip comes to us from Igor Khayet, founder of My Resume Shop.

As a professional resume writer, one of the most common questions I get asked is how to shorten a resume to one page without losing critical information. The first tip of this series explained how to decrease the number of sections on your resume, the second tip provided advice on reducing the quantity of bullets and the third tip explained how to cut excess language.

Check out this week’s tip below, and be sure to stay tuned for the next pointer!

Tip #4: Remove Unneeded Information

The resume is as much about what you don’t put on it as it is about what you do put on it. Remember that a concise resume is particularly powerful because of its focus and relevance to a specific set of skills and experiences needed for a position. Unneeded information is anything on the resume that is not required (by the employer or graduate school program), nor particularly relevant for the job at hand. Here is a short list of unneeded information:

  • Objective Statements: Objective statements — usually a section at the top of a resume that summarizes your career goals — are outdated, and their content should be included in cover letters instead. Ideally, the objective is evident throughout the resume because of a targeted choice of experiences.
  • References: Unless specifically asked to include references, you should leave them off the resume, including the line “References Available Upon Request.” This is obvious that they are available, so there’s no reason to waste space saying it.
  • Political Affiliations/Experiences:  The only exception to this rule is if you are applying to a political organization and want to show your involvement. Otherwise, discuss these experiences on a high level without mentioning political parties.
  • Salary History:  Not appropriate or relevant. (although some federal government agencies require this information).
  • Reason for Leaving Past Employers: The resume is not a place to explain why you left a past employer. You can do this in the cover letter or in the interview.
  • Personal Information: In some countries it is acceptable and even encouraged to include personal information such as marital status, DOB, etc. In the U.S. you should stick to the basics: Name, Address, Email, Phone. That’s it.

A 7-Step Plan for Using Blogs in English Classes

February 6th, 2011

Whether you’re a techie who holds after-school Skype seminars or an old-school prof who demands stapled, hard copies on your desk by 5 PM sharp, you can use blogs to keep students engaged in and out of the classroom.

If you’re new to integrating blogging into your lesson plans, here’s a sample plan of action.

1. Decide which blogging platform to use

Blogging platforms like Tumblr, WordPress.com, Edublogs.org and Blogger.com provide free, easy ways to create blogs for your students — no technology knowledge needed!

Choose one platform and require every student to use it – no matter their personal preference. Even if students already maintain a personal blog, be sure they create a new blog solely for the purposes of class. Collect each student’s blog address and distribute the list to the class via email.

2. Start with an assignment that works as an old-fashioned English paper

God forbid that technology should actually detract from the goal of your classroom—which is to explore the art of written communication. Ease into incorporating blogs into the classroom by assigning a “traditional” English assignment, but requiring students to post their finished product on their blog.

Let’s say you’ve tasked your class with the following assignment.

Be sure to define the parameters for the assignment – their blog shouldn’t be an excuse for students to slack off! Clearly identify grading criteria, and make sure students understand that if you ask them to post the final draft of a paper on their blog, you will hold it to the same standards of grammar, style, and mechanics than you would a printed essay.

3. Get those comments rolling

Once students have taken the first step – posting their “traditional” English paper on their blogs – it’s time to exercise the full capacity of the blog genre.

Instruct students to read each others’ essays and post comments on, say, 6 or 7 of them. Indicate that you will check to make sure they make the required number of posts. Encourage students to offer both praise and constructive criticism of their peers’ work, and spell out your standards for respectful online interaction. When properly monitored, internet forums give even the quietest students a chance to enter class discussion.

Read all the posts and summarize the discussion threads in the classroom the next day, and open up the online discussions to the class.

You might also ask students to write a reflection post about the above activities, answering questions such as:

  • What comments on your paper surprised you?
  • How do you think you might have improved your argument?
  • What did you learn about the writing or reading process with this assignment?
  • Do you have any plans to expand your 2-page argument?

For the midterm or final paper (whether it’s a 5- or 15-pager), allow students to build upon their essay.  Have them blog about the process of expanding the paper – ask them to post their revised thesis on the blog, or to document their research questions. The key is to make students feel a sense of ownership over their work in the class.

4. Encourage discussions between assignments

After their first assignment, students will be more familiar with the workings of their blog — if they weren’t already. Instruct students to post questions (about classroom material) or writing/research challenges they are facing on their blogs. Offer extra credit to students who post helpful feedback on other students’ blogs; consider grading “blog participation” as a component of students’ class participation grades.

5. Reflect on the research process

If you incorporate any amount of research in the class, you may have students post about their research efforts—what’s working for them, what’s not and how they see their work evolving. Encourage students to use their blog to link to helpful resources they’ve found on the web.

6. Showcase creative talents

If you incorporate any amount of creative writing into your English class, blogs are a great way to help students “jump into” different characters. Students might post full stories or poems on their blogs – or they might post individual scenes, character descriptions, or “free-writes” to get their creative wheels turning. If creative writing is the main purpose of your students’ blogs, it might also work to create a single class blog, like the one above, where students can share their own work or inspirational excerpts from the work of published writers.

The advantage of the blog format here is that students who are usually paralyzed by the blank page may find it easier to write when publishing and feedback can happen more instantaneously.

7. Explore other assignments

Depending on the English class you’re teaching, you may have the opportunity to incorporate “top ten” lists, opinion articles, and “how-to” essays into your syllabus. These assignments lend themselves well to being published on blogs. If you’re teaching a “specialty” class like Journalism (see below), a class blog might also be a helpful resource.

How to Improve Student Content Retention: A Tale of Two Classrooms

February 5th, 2011

American math teachers frequently complain about the mastery level of their incoming students. College professors are frustrated because they find themselves having to teach high school level material. High school teachers are frustrated because they have to teach middle school material. Middle school teachers are frustrated because they have to teach elementary school material.

Evidence backs up their collective lament. According to multiple international assessments, American high school students rank in the bottom half of industrialized countries when it comes to math achievement. Numerous East Asian countries boast much better test scores and content retention even though countries like China, Japan, and South Korea spend less per student and often have larger class sizes.

So what are teachers in East Asia doing that helps students retain what they learn? Turns out, there is a key difference in pedagogy that Western teachers can emulate.

Lesson Structure in the U.S.

In the United States, a typical math lesson looks something like this:

  1. Teacher introduces and explains a new concept
  2. Teacher demonstrates several sample uses
  3. Teacher gives students related problems to solve in class
  4. Students complete homework and eventually take a quiz, both of which contain similar problems to the ones in class

A lesson on exponents, for example, would begin with the teacher writing 2^3 on the board,  telling everyone that it signifies 2 × 2 × 2, and then giving more examples. The second half of the lesson would be arithmetic problems where students compute 3^3, 5^3, and so on and so forth.

A general rule of communication is that what you end with is what you emphasize. Therefore, in the lesson structure described above, the emphasis is on problem solving, not on the actual mathematical concept. The implicit and often explicit lesson to students is:

“Don’t worry about understanding the math: just try to get the questions right.”

It turns out that this method may be less than optimal, both for learning math and also for acing standardized tests.

Lesson Structure in Japan

Japanese classrooms, by contrast, use the exact opposite structure. A typical math lesson in Japan looks something like this:

  1. Teacher presents a problem
  2. Students attempt to solve this problem using their existing understanding.
  3. The teacher works with the class, using the process to help students deduce a new concept.

For example, in Japan, instead of just explaining the rules for exponents and then spending forty minutes on practice problems, the teacher will start by showing students 2^3 = 8 and 3^2 = 9 and focus on getting students to see the pattern and deduce what operation leads to these results.

By “proving” the mathematical concepts and making them the focus of the lesson, East Asian teachers can significantly improve long-term retention of content.

Takeaway

The goal in all teaching is to leave students with the feeling “I have this new skill / understanding that I did not have at the start of class!” instead of “Great, now I may do a little better on my standardized tests.” The latter sentiment motivates only the high-achievers and sends the message that what you are teaching lacks intrinsic value.

Though this lesson structure is particularly applicable to math, it can be applied to almost any subject. Making an effort to ensure students understand the concepts involved rather than just demanding rote memorization will pay off in the end.

Student Spotlight – Curt Smith: Entrepreneur, Dad, and iPad Winner!

February 4th, 2011

Though Knewton students get plenty of face-time with their teachers, it’s not often that we get to see our students’ faces… until now! In our new Student Spotlight feature on our blog, we’ll highlight just a few of our rock-star GMAT students. If you’re a current or former Knewton student and are interested in being featured in the spotlight, just leave a comment on this post!

For our first installment, who better to feature than the oh-so-lucky winner of Knewton’s iPad giveaway on Beat the GMAT?

Name:

Curt Smith

Hometown:

Colorado Springs, CO.

Current job?

Entrepreneur (I own a construction company, a website (www.thepictureboard.com), and dabble in other random things.

How’s it going?

It’s going well.

Why do you want to get an MBA?

To better run my companies, network, and further my knowledge in business.

What’s your dream job after b-school?

Entrepreneur/Knewton’s spokesperson and success story.

What do you think of Knewton so far?

I have loved the Knewton courses. I am in a different situation than most studying for the GMAT. I only recently decided to try to go back to school and want to get in for this next fall semester, which means that I only gave myself 2 weeks to study for the GMAT. Yikes!

I wanted to take a class but needed one that I could start immediately. Other test prep places I called only had 2+ month long classes, so I bought a “Cracking the GMAT” book from another company and read the thing cover to cover, only to find that it did not even increase my practice scores. I came across the Knewton courses on BTG and signed up. It was perfect for me. I could take as many classes as I wanted whenever I wanted. It is the perfect situation. Even if I didn’t get the score I wanted, I had access to all the classes for an entire year!

So I buckled down and studied 14+ hours a day for a week. I only made it through half of the lessons and homework and 3 practice tests, but when test day came this week, I was shocked to find that my score went up 90 points! I actually scored higher than I had on any practice exam! Even though I got the score I need for the schools I am applying for, I am almost tempted to do all the classes and see how high I can really score. I really think that almost anyone can score 700+ if they go through the entire Knewton program.

How about the On-Demand lessons?


I only took the On-Demand lessons, and they were great!

Any teacher shout-outs?

Since I only took the On-Demand lessons, I got to know David & Jen, and Rich & Jess very well.

Lightning Round: Favorite song right now?

Wheels on the bus (I have a 2-year-old, what can I say).

Data Sufficiency or Sentence Correction?

Data Sufficiency.

Bill Gates or Steve Jobs?

Both. I couldn’t do my job without Bill and I couldn’t play on my fancy new iPad without Steve.

Harry Potter or Twilight?

I think being a wizard would be far better than being a glittery vampire.

Happy Chinese New Year: 12 Proverbs for GMAT Success

February 4th, 2011


As those who follow the Chinese Zodiac know, we have officially entered the Year of the Rabbit. If you were born in 1975 or 1987, then this is your year. I don’t know how much you believe in horoscopes and astrology, so I won’t bother with any predictions. Instead, I’ll give you some more practical advice for your upcoming GMAT.

In celebration of the year of the Rabbit, here’s a list of  12 Chinese proverbs to help motivate you to GMAT success. These are proverbs that have been passed down for thousands of years and have helped many Chinese students succeed in their studies. Hopefully they will help you too!

Since it is the Year of the Rabbit, that’s where we’ll start.

1. The Rabbit says, “Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime.”

In other words: Having the answer is not as good as knowing how to find the answer. If you are stuck on a particular problem, getting the answer will get you past it. But understanding the method for solving the problem will also help you solve similar problems in the future.

2. The Dragon says, “I hear and I forget. I see and I remember. I do and I understand.”

It is not enough to listen to the teacher and watch how the problem is solved. True mastery of a skill comes from repeated applications of that skill.

3. The Snake says, “The palest ink is better than the best memory.”

Memories are merely temporary synapses between neurons in our brain, but notes written down will be there forever.

4. The Horse says, “He who asks is a fool for five minutes, but he who does not ask remains a fool forever.”

Don’t ever hesitate to ask a question. A question is doubt that lingers until it is answered. Lingering doubts will lower your confidence over time. And confidence is critical for success on the GMAT.

5. The Ram says, “Teachers open the door, but you must enter by yourself.”

Teachers only provide the tools that you need to be successful. You’ll have to put it in the hard work and practice on your own in order to achieve true mastery.

6. The Monkey says, “A book tightly shut is but a block of paper.”

No matter how great your book (or GMAT prep course!) is, not using it is like not having one at all.

7. The Rooster says, “Habits are cobwebs at first; cables at last.”

Bad habits are difficult to break, so why not install some good habits instead? Commit to a positive action for 21 days and it will become a habit you can benefit from for life.

8. The Dog says, “A gem is not polished without rubbing, nor a man perfected without trials.”

Do not be intimidated by tests. Tests are the best ways of finding your weaknesses. Overcoming those weaknesses will make you strong.

9. The Pig says, “Learning is a treasure that will follow its owner everywhere.”

It may seem like you are just learning for the GMAT, but the skills you are acquiring will likely help in ways you can’t imagine. No effort is ever wasted.

10. The Rat says, “Be not afraid of growing slowly, be afraid only of standing still.”

Don’t get discouraged when your score isn’t increasing as fast as you wanted. Be encouraged by the fact that you are putting in the effort to master the necessary skills.

11. The Ox says, “Behind every able man, there are always other able men.”

Studying for the GMAT does not have to be a lonely experience. Reach out to others for support and you will be surprised by the amount you receive.

12. The Tiger says, “Men trip not on mountains, they stumble on stones.”

Are you struggling with solving equations? It could be that simple exponents are what’s tripping you up. Dig deeper to find what the real problem is.

I hope you have gained some wisdom from these proverbs. Now take these words and go make your ancestors proud!

Video: Intro to Data Sufficiency on the GMAT

February 4th, 2011

In part two of Knewton’s Intro to GMAT Quant lesson, Jess and Rich walk you through the fundamentals of Data Sufficiency. Learn the two main types of DS questions you have to recognize on test day, and see how you do on an example of each one.

Be sure to check out Rich and Jess’s rule that has to be second nature for every GMAT student: On Yes/No Data Sufficiency questions, “no” does not necessarily mean “insufficient”!
