Beyond Random: More New Questions For Everyone!

beyond_randomAlthough we have hundreds of practice questions for both the SAT and the GMAT, some of our more dedicated members were seeing repeat questions.

So, Grockit now keeps track of the questions you’ve seen and only shows you new ones. There are a couple of exceptions:

If you haven’t gotten it correct yet it’s fair game for obvious reasons.

If you have answered it correctly but a teammate hasn’t you may see the question again. This has two benefits: Your teammate gains from your experience with the question and teaching others is a great way to further your mastery.

The no repeats feature along with our ever increasing question pool will set you up for many hours of productive studying for the GMAT or the SAT.

Virtual Schooling Works

Here are a couple of interesting quotations from a recent article about virtual learning and schooling on Education Week.

‘“We know it’s ‘as good as, if not better,’ in terms of student achievement,” says Rick E. Ferdig, an associate professor of educational technology at the University of Florida, in Gainesville, who runs the Virtual School Clearinghouse research project. The project enables states to analyze their own statistics and pool data, making it publicly available for researchers to conduct studies.’

‘Cavanaugh says some of the states that are starting to see good results are also using adaptive-intelligence technology that allows students to skip over content they’ve already mastered and move on to the concepts that give them trouble.’

The article also goes on to mention that there is still a lot to be learned in terms of which methods work and which don’t.

If you have any experience with virtual schooling, please share!

Varnish Your Website For Heavy Traffic

We are looking into various page caching methods for Grockit web pages. Page caching facilitates faster loads on pages that are being simultaneously hit by many users.

Currently we are exploring Varnish as a possible page caching solution and we would love to hear about people’s experience with Varnish or other page caching solutions.

Interestingly, the Varnish project was started by the online division of Norwegian tabloid newspaper Verdans Gang. The lead developer being Poul-Henning Kamp with additional support by Linpro, a Linux solutions company.

Your Reservation Will Be Held For Five Minutes

picture-9

Grockit games can be started immediately or scheduled for later. When you RSVP to a scheduled game we used to hold your spot for the entire duration of the game regardless of whether or not you showed up. Sometimes, however, spots would be filled but the player would not show up. This in turn could prevent someone from joining a GMAT game that has available spots but is ‘full’ becauase all the spots were filled by RSVPs. To remedy this and give people more opportunities to work on GMAT questions together your reservation will now be held for the first five minutes of a game. So, if you show up to the game you RSVP’d to, no worries, you’ll get to keep your spot, but if you’re more than five minutes late to the game, your spot will be opened up for anyone to join. That anyone could be you or someone else that is in the GMAT lobby looking for people to collaborate with.

Review Page Pagination

picture-7Part of closing the loop on your learning is to review the work you’ve done. In Grockit, we provide this functionality with our post game reviews. Each game you play in Grockit spawns a review session. In a review you get…..

1. Detailed expert explanations for every question you’ve played in the game.
2. Chat history of your discussion around each question.
3. A global comment stream sourced from other players that have reviewed that question.

If you’ve been playing in Grockit a lot, you probably noticed your review list getting pretty long and potentially taking a few moments to load on the page. We’ve addressed this issue by adding pagination to the reviews page.

You will now see your review list broken down with ten reviews per page with a cool little pagination list at the bottom.

To implement the pagination we used will_paginate, developed by the team at GitHub.

Design Deliverables for Agile Planning & Development: A Clickable Collection of Mock-ups

pseudo-version of grockit exported from Fireworks

We’ve tried a few different approaches to communicating design at Grockit. Our process is constantly evolving but I feel like we’ve reached an ah-ha moment so I thought I would share in case there are any designers out there working with agile development teams that might benefit from what we’ve learned.

In a nutshell, we create a clickable psuedo-site (“click-thru”) that is interlinked as needed to communicate interactions. The index of the click-thru is the go-to place whenever we want to reference a design. In my experience, this has proved superior to attachments-to-Tracker-stories or a folder of flats because it seems to be easier to find things and most importantly it lets me demonstrate interactions and conditional changes.

I also use the click-thru as a place for collaborative exploration. For me, it’s inspiring to make changes to something that teammates will notice. It speeds up the feedback loop and increases the amount of encouragement I get, which makes me happy and more productive, so I make more mock-ups, …etc. One example of using the click-thru for experimentation is the layout and content of the Game Lobby, in the click-thru right now the SAT lobby is different than the GMAT lobby, one represents the next incremental design while the other represents a future version many iterations away. Note: the click-thru is always delivered with the expectation that not all the links will work, and it is almost always presented with narration.

Tools to create the click-thru and to communicate the plans we derive from it are:
* Adobe Fireworks
* Dropbox
* SubEthaEdit
* Pivotal Tracker

To maintain the click-thru we set up Fireworks files with slices over buttons that lead to other pages. When a flow is mocked-up and linked together we then export html and images. Since we use Dropbox and everybody shares the folder the update gets shared with no extra effort on my part. Then we write stories collaboratively with SubEthaEdit …and usually modify the mockup while we are writing the stories. We import the stories into tracker and then the team assigns points to the stories with the click-thru for reference.

The click-thru then becomes a reference for implementation that is still malleable and can be used as a starting point for further collaboration if we discover a more compelling alternative. Alan, Lane and Tim from Cooper Interactive stopped by our office recently to check-out our style of Agile and they asked if we keep the click-thru up to date if we make changes during the implementation process. If we change the design slightly during implementation we will not update the click-thru, it’s simply an artifact at that point and the application itself is the current iteration of the design. I’ll only update that section of the click-thru if we are building something more on top of it in a subsequent iteration.

What will be especially interesting is to see how this process evolves with more than one designer at Grockit. If you know a designer (maybe you?) interested in working in an agile environment, please get in touch.

New Top Players List

picture-61

We have updated our GMAT top players list to calculate the list on a weekly basis. Until now, the top players list has been calculated over all time. This led to a list that was very static and difficult for a player to get on. By switching to a list calculated over the past 7 days there is much more opportunity for a player to make the list and it also shows a fresher picture of who is working a lot on a particular test within a more relevant time frame. We may add the top players over all time list back as an additional view. Now go get working on your GMAT and get on that list!

Grockit Predicts Test Scores With Astrology

Astrological Test Score Prediction

At Grockit we are committed to research and development. We work diligently to incorporate cutting edge learning theory into our products and code. To this end, there are several exciting initiatives we have been working on in the Grockit Labs.

Today we are proud to announce the implementation of our research around test scores and their relation to your astrological reading. It turns out that your birthdate and the date of your actual test have a strong infuence on the outcome of your test.

So, we have built an algorithm that takes into account your birthdate, the date of your test and standard astrological knowledge to provide you with an expected score for your test. Even more exciting is our algorithms ability to recommend a test date for you based on the same data.

According to our analysis, students can see score improvements from 10-50 points on their standardized test by picking a test date that aligns with the stars. Sure, studying and practice, practice, practice are the best ways to prepare for any test, but the power of astrology cannot be discounted.

We look forward to sharing more about our efforts at Grockit Labs. Good luck on your test and may the stars be with you!

Here is some preliminary data on our findings. Personal results may vary.

GMAT for Aries
Your first instinct is always brilliant, and almost always right. Not everybody knows that the GMAT favors your sign, but now you do. Don’t bother studying, just be you. 760

GMAT for Taurus
Your beauty and good taste are your only hope for this fateful event. Your only hope is to reschedule, but if you can’t do that, at least you can blame the stars. Remember that you have other talents. 230 (ouch)

GMAT for Gemini

Use your super-twin powers to achieve total GMAT domination. Your verbal side gets it and your quantitative side is a machine. But beware, your over-active imagination may exhaust your reserves on the essay section. Stay focused, stay focused. 740

GMAT for Cancer
Imagine the GMAT is a piece of chocolate cake with your name on it. This is not the time for a diet! Apply your love of food to every question, savor the questions, own the GMAT. Good luck. 680

GMAT for Leo
It’s all about you Leo, every question that has been written and tested has been in anticipation of your big test day. You can do no wrong, everybody loves you when you take the GMAT. 800

GMAT for Virgo
Your desire to keep everything organized and your methodical approach to questions will not aide you today. Sorry Virgo. If cheating was an option we’d recommend sending a Leo in your place, but for you the stars recommend rescheduling. (Reschedule or decline your score.)

GMAT for Libra
OK Libra, do you think you can stop thinking about your boyfriend/girlfriend for 3 hours? Actually, we know that you CAN’T. Your only hope is to pretend that the GMAT is your boyfriend/girlfriend. Test your heart out. 620

GMAT for Sagittarius
Sagittarius, your destiny is in Business School, nothing can prevent you from fulfilling this goal, including the dismal performance on the GMAT you are about to demonstrate. Letters of recommendation are your strength. 450

GMAT for Scorpio
Using your connection to Pluto you will see through the questions and answer with laser-eye focus. Scorpio you are on fire! 780

GMAT for Capricorn

We know that you’ve been studying diligently, you’ve done everything right, too bad the stars aren’t going to align for you. Avoid certain failure by rescheduling. (Reschedule)

GMAT for Aquarius
Your imagination and wacky sense of humor is your strength. You will fail both Quantitative and Verbal but your essay will be so compelling that it will be published in the Atlantic Review and you will be awarded and honorary score. 780

GMAT for Pisces

Like a fish out of water… poor Pisces, you won’t even find the test center. 200
