Video: The Basics of Independent and Dependent Equations

March 20th, 2011

In this video, Jess and Rich cover the basics of independent and dependent equations on Data Sufficiency questions. Here are some of the concepts they discuss:

  • Systems of equations are dependent if one equation can be formed by manipulating and/or combining the others.
  • If no manipulation/combination can create dependent equations, the equations are said to be independent.
  • We need n independent equations to solve for a system with n variables.
  • Dependent equations give us redundant information, so they don’t help us solve for all variables.
  • If we try to solve a system with dependent equations, we will find that doing so is impossible. We will end up with an identity.

MBA Life on Youtube: Rethinking the MBA at HBS

March 19th, 2011

If you’re considering business school, it’s likely you’re no stranger to the ongoing debate about the value of an MBA. In this video, Harvard Business School professor David Garvin discusses the way in which business schools are shifting in response to ongoing critiques — specifically, by emphasizing applied experience in addition to knowledge.

While this video is from last year, it provides a useful primer to the issues being discussed by people like Josh Kaufman (of “The Personal MBA” fame). Recently, HBS announced 5 new priorities for the school, including one initiative that seems directly tied to the issues discussed in the video. In the new FIELD (Field Immersion Experiences for Leadership Development) program, required for first-year students, students will be encouraged to apply their core academic knowledge to a real-world problem.

What are your thoughts about the worth of an MBA today? Let us know in the comments, and be sure to check out the full series of MBA Life on Youtube posts for more.

GMAT Reading vs. Everyday Reading: What Makes GMAT Passages Tricky?

March 17th, 2011

If you’ve started studying for the GMAT, you know that reading passages on the GMAT is very different from reading “normal” things–novels, newspaper articles, magazines, blogs. Check out our first GMAT Reading vs. Everyday Reading blog post for more.

If you’re looking to enhance your GMAT Reading Comprehension skills, the best things you can do for yourself are:

  • Understand what exactly makes GMAT passages tricky
  • Develop strategies for processing complex information, so that you can attack the questions efficiently

So, what can you expect on the GMAT? How are GMAT passages structured differently from normal prose?

On the GMAT, you shouldn’t necessarily expect arguments to be concise or neatly summarized. In fact, the test-makers will often intentionally try to confuse you by providing passages that ramble or contain insignificant details.

Let’s take a look at how this works in a GMAT passage. Here’s an example (pay close attention to how each bit of information is related to the passage as a whole):

The passage above begins with a main point and some supporting information. Then, there’s a digression — the  “support of the support” — before the passage returns to the main idea.

Keeping this structure in mind, how can we adjust our reading on the GMAT?

Being able to distinguish between the main idea of the passage and the supporting details will help you increase accuracy and save time on Reading Comprehension.

Practice finding the main idea in different types of GMAT passages. That way, on test day, you won’t waste time with superfluous details!

To review:


In short, it’s natural to feel like you’re “fighting an uphill battle” with GMAT reading comprehension passages. The key is to keep your calm and employ the reading strategies described above.

Good luck on the test!

7 Social Media Tools to Use in the Classroom

March 17th, 2011

Looking for a way to incorporate social media into your classroom without unleashing your students into the free-for-all that is Facebook and Twitter? Check out these 7 social media tools created specifically with students in mind.

1. Edmodo


 

 

As a Twitter in “training wheels,” Edmodo allows teachers to connect with students in a safe, self-contained environment. Here are a few possible uses:

  • Have students collect and report snippets of data about a scientific phenomena (weather, rainfall, wax and waning of the moon, growth of plants, etc) they witness in their environment.
  • For social studies, have students send snippet-reports about current events and share links to relevant blogs and websites.
  • Create “reading” groups where students can tweet their questions and reactions to classics like Huckleberry Finn and Catcher in the Rye.

2. SchoolTube


 

 

This is basically YouTube with bumpers. Here are a few reasons to get in on this community:

  • All videos on SchoolTube have been approved by a moderator or SchoolTube staff to ensure appropriateness. Videos are sorted by both category and channel for easy browsing.
  • Everyone can share their videos on SchoolTube. Students can view the creations of students from across the nation.
  • Students and teachers can create their own free channels for classrooms, clubs, sports teams, or after-school programs.
  • SchoolTube hosts a number of educational contests with prizes that include electronics, t-shirts, and cash!
  • Staff-picked ”videos-of-the-day” help teachers discover and share noteworthy channels.

3. Glogster


 

 

Forget construction paper and glitter – Glogster.edu lets students feel like professional designers as they create “interactive online posters.” Whether they’re reporting on the rainforest, the Civil War, or the Boston Tea Party, students can use Glogster to showcase their knowledge and express their views. Current features include sound and image/video upload. Tagging, file-sharing, and a new webcam recording feature are coming soon!

Here’s an idea:

  • Create a “Grand Exhibition” using Edmodo and Glogster. Tweet out the links to 10 student glogs and let students admire each other’s creations and comment.

4. Prezi


 

 

 

With its zooming, rotating, and swiveling features and thrilling variety of fonts and textures, presentations on Prezi are guaranteed to rivet audiences. As one reviewer describes it, “think of Prezi as a 3D infinite canvas.” Just “write,” “zoom,” and “arrange” your way to wow-dom.

Some dazzling examples:

5. Diigo


 

 

What if you could highlight, underline and write in the margins of websites – just like you do in print books? Well, you can with Diigo, the new social “bookmarking” tool which allows you to annotate the web, superimpose your notes on web pages, and share your scribblings with others!
“Educator” accounts include the following special features:

  • You can create student accounts for an entire class with just a few clicks (and your students don’t even need email addresses!).
  • You can create “groups” – with group bookmarks, annotations, and forums.
  • Diigo offers privacy settings, so that teachers and classmates can communicate only with each other in a self-contained environment.
  • Special accounts make it possible to limit student exposure to ads.

6. Quizlet


 

Here’s a tool that will allow you to make flashcards quickly and share them with everyone in your learning community. Great for biology, foreign languages, and vocabulary!

Check out a sample creation here.

7. Wordle


 

Want your students to experiment with language and see words in a whole new light? Try Wordle–one of many online word-cloud generators. Students can paste in a URL or a block of text; the word-cloud gives greater prominence to the more frequently occurring words. Students can change the font, layout, and color scheme of their clouds, and share it with their friends.

Here’s a word-cloud made from the text of this blog post:

 

 

 

 

Ready to make your own? Check out a short video on 50 ways to use Wordle. Here are a few ideas to get you started:

  • Create word clouds of synonyms and antonyms
  • Explore rhetorical devices such as alliteration, rhyme, and onomatopoeia
  • Create a Wordle “author quiz” by making a series of clouds which represent the diction used by different authors. Have students guess which clouds correspond with which authors.
  • Have students “brand” themselves by creating clouds of their favorite words or the words which best describe themselves.
  • Have students keep a “cloud-a-day” weekly word diaries (students create clouds with new vocabulary words or words that strike them which they hope to incorporate into their own vocabularies).
  • Have students make up neologisms and nonsense words and display them in clouds to share with each other.

 

 

MBA Admissions Tip: Extracurricular Activities

March 16th, 2011

This post comes from our friends at Clear Admit. For more MBA admissions advice, check out their blog.

Because it’s the time of year when applicants aiming for Fall 2012 intake are just beginning to think about the admissions process, we wanted to focus today on one element of the application that candidates often underestimate: extracurricular activities.

In order to understand why this category is important, candidates should keep in mind that the adcom is responsible for crafting a dynamic class each year. The aim is to admit individuals who will support a vibrant campus community and step into leadership positions. In other words, as admissions officers consider each applicant, they ask themselves “what’s in it for our school?” An applicant who has previously demonstrated a talent for writing, for example, by contributing to a non-profit’s newsletter, will really catch the adcom’s attention if she also expresses her intent to contribute to a specific publication on campus.

Volunteering is of course a great way to expand one’s extracurricular involvement. However, many applicants participate in the occasional fundraising walk or an annual corporate outreach day; those who demonstrate ongoing involvement in one cause or organization will be of special interest to the admissions committee, especially if it is related to their current or future career. A candidate who has contributed over a longer period is likely to have developed his or her responsibilities beyond ladling soup or stuffing envelopes. What’s more, this can be a particularly important opportunity for applicants who are currently living and working outside of their home countries; for example, an Indian applicant who works and volunteers in Africa will stand out as being particularly engaged and well-adapted to his or her foreign environment.

Candidates who are older or younger than the average applicant should recognize that their extracurricular involvement is particularly important. A younger applicant who lacks leadership responsibilities at work might demonstrate his talent for motivating others outside of the office. Meanwhile, older applicants can use their extracurricular involvement to reassure the adcom that, despite family responsibilities or distance in age from one’s classmates, the broader life of the community remains important to them.

Lastly, applicants will have a much easier time writing their application essays if they have a variety of experiences from which to draw. While applicants can certainly respond to most essay prompts by reflecting on their professional experiences, relying exclusively on one’s work is a mistake. With each essay, the applicant should aim to share a different side of him or herself – submitting five essays about electrical engineering or investment banking is not the most effective way to do this.

We hope that this sheds some light on the opportunities and value that activities outside of work provide with respect to one’s b-school candidacy and applications. Should you find that area of your application lacking upon reflection, the good news is that there’s still plenty of time to address this before the deadlines. Whether that means volunteering your professional services to a local non-profit, joining a community mentoring organization or brushing up on your competitive square dancing, Class of 2012 aspirants should aim to make this an especially active and productive spring and summer!

5 Tips for an Excellent MBA Admissions Interview

March 15th, 2011

This post comes to us from Igor Khayet, President and Founder of My Resume Shop.

You’ve already submitted your b-school apps. Finally, you get the call or the email. Nope, you’re not in — yet. Button your blazer; it’s interview time.

Just like rounding the bend on a racetrack, catching a glimpse of that finish line can push you to step up your game or lead you to stumble. Lucky for you, there are a few surefire ways to ensure that you turn those fifty minutes of interview face time into an MBA admit.

1. Research the school.

Ever go on a blind date without a quick Google search first? Exactly. Research your school. You already wowed them with your essay; now make sure you’re ready with an arsenal of quick facts about why their school is the perfect place for you. This will also keep you from making embarrassing mistakes, like expressing interest in a student club they don’t have. And it’s not just the online due diligence that counts. Professors and current students in your field of interest are excellent sources of advice and will provide you with the nuance you need to seem “in the know.” Details are key — a simple “I just like you” might convince someone on a first date, but not in an interview.

2. Think about the “Why’s”.

In most cases, there are only a few key questions that are going to make or break your interview, and they are likely very similar to those you addressed in your essays. Let’s start with the basic three: 1) Why do you want to get an MBA? 2) Why now? 3) What are your short and long term goals? It’s absolutely necessary that you have prepared thoughtful answers for these questions.  You spent the money to apply, so there must be some compelling reason you want to go. Make sure you can convey that well on interview day.

3. Turn on the charm.

Don’t go overboard — this isn’t The Bachelor — but do make sure that you use your personality to make a meaningful connection with the person across the table.  Think beyond flattery; instead, focus on developing a certain rapport based on a shared interest in business school and any other topics you discuss.  Be sensitive to the feedback you are receiving and try to adjust your conversation accordingly. When it seems like you’ve touched on something of mutual interest, make an effort to engage in a more in-depth discussion. A meaningful connection will make a much greater impression than a game of 20 questions.

4. Tell a story.

Have a hard time reading Kant, yet find the moral reasoning of Aesop’s Fable’s surprisingly clear? Well, that’s because framing information in a narrative provides the necessary logical links your brain needs to be able to absorb and retain information easily. Make things easy on both you and your interviewer. Rather than just shouting out facts and numbers, have one or two stories from your experience ready to address a broad range of potential topics. The best kinds of stories will highlight a variety of positive qualities or skills. A single story, for example, might describe not only your leadership potential, but your analytic skills and knack for problem solving as well.

5. If you’ve got it, flaunt it.

This is your last chance to show your dream school just how right an MBA is for you and your goals — and not just any MBA, their MBA. These interviewers have been sitting in their seats all day for days. Excitement is contagious and will leave them with a good impression about your candidacy. This doesn’t mean that you should bring out the confetti and party hat (too much eagerness can be unsettling) — but hold on to those. You’ll be needing them for when you get that acceptance call.

Can you tell us a bit about your experience prepping for the GMAT?

I invested 14-16 hours a week before the exam. I completed all the practice exercises and tests in the GMAT books – Kaplan/Princeton/GMAT Official Guides. On the whole, I took 6 online GMAT tests before the exams. I went over few materials that I had downloaded from different websites and also the strategies/tips offered in Beat the GMAT community. I was able to crack almost all the questions on time but some times I ended up choosing the trap answer. That was a real challenge for me! From my experience, I feel two techniques are very important in GMAT: applying the strategies and time management.
