Maplesoft is a long standing supporter of the Who Wants to Be a Mathematician contest for high school students. For years, we have donated Maple as prizes to winners of the national and regional contests.

This year, being the 25th anniversary of Maplesoft’s incorporation, the company decided to support several projects that encourage the use of math amongst high school students and young adults. We dedicated a bigger budget towards projects that would enable us to make a significant impact on students and impress upon them the need for math and science in their future careers.

One project we undertook this year is giving an extreme makeover to the Who Wants to Be a Mathematician contest! With Maplesoft as a “Technology Sponsor”, the contest that was administered on pen-and-paper moved to a digital format. We donated our testing and assessment tool, Maple T.A. to administer the tests online, making the software accessible to every student that participated. This meant the students took an online test, and were automatically and instantly graded using Maple T.A.

The 2013 competition is underway, and the results are extremely positive:

  • The number of students that participated in the contest doubled this year, with over 2000 students from over 150 schools participating.
  • The competition introduced a second level of tests, making the competition more rigorous. After the first elimination round, eligible contestants moved to a second round with questions of increased difficulty levels.
  • By avoiding much of the paper work and manual corrections, the organizers saw significant savings in time and money.

Custom test questions were created in Maple T.A., which were accessed by students from a server hosted by Maplesoft. The simple and easy to use interface of Maple T.A. enabled the students to take the test without spending time learning the tool. Maple T.A. supports the use of standard mathematical notation in both the question text and student responses. Maple T.A. also allows free-response questions, including questions that have more than one correct answer.

Who Wants to Be a Mathematician is a math contest for high school students, organized by the American Mathematical Society (AMS), as part of its Public Awareness Program. Ten students will be chosen for the semifinals and two will qualify for the finals to be held at the Joint Math Meetings in January 2014.

More information about the contest that is currently in progress can be found on the AMS website

 

Hello!

If I wirite in an algorithm in MapleTA 9.5 the number 0, and later use it (for export to latex), it becomes negative, but not if I pass through Maple:

 

$null=0;
$zero=maple("0");
$nullstring="$null";
$zerostring="$zero";

results in:

null 0
zero 0
nullstring -0
zerostring 0

 

Why, and what can be done without passing through Maple?

 

Best,

Jan

Hi When Im creating subjects and child subjects you would think it would be kept in alphabetic order. But no. It just becomes one big chaos after refreshing browser. What am I doing wrong? Btw what is the difference between subjects and groups inthe question repository? Thanks in advance, Henry

We’ve recently added a new set of questions to the Maple T.A. Cloud for English language proficiency tests. These questions demonstrate how Maple T.A. can be used to generate text-based questions that take advantage of the randomization feature. These questions were created by Metha Kamminga, an Independent Learning Professional in the Netherlands. Metha is a strong proponent of Maple T.A. in Europe, and transformed the testing and assessment system in Delft University before her retirement.

TU Delft University aims to transform learning through the use of technology. Its ambition is to eventually offer fully digitalized degree programs and it believes that digital testing and assessment can play an important role within this process. They are using Maplesoft’s online testing and assessment suite, Maple T.A., to move their courses to a digital assessment environment. To read the full user story, click here.

Visit the Maple T.A. Cloud to access the questions mentioned above and to browse the full collection of questions.

I just wanted to remind everyone that this quarter's Möbius App Challenge closes Sept. 30.  This quarter's prize is an iPad Prize Pack, which looks very cool but sadly, I'm not allowed to enter.

To enter the contest, all you need to do is:

1) Create an interactive App in Maple

2) While in Maple, log-in to the MapleCloud through the MapleCloud palette.

3) Click on the Send Document to the Cloud button

Hi,

Our school is using a hosted version of Maple TA 9. We have a lot of questions in Moodle we would like to export to Maple TA. Is this possible?

Thanks in advance,

Henrik

How would i go about integrating

(1)/(x^2+2)

 

I know it has to do something with arc tan but it doesnt match up completely what would I be able to do?

I am happy to formally announce Maple T.A. 9.5! An expansion on Maple T.A. 9, this release is packed full of innovative features and new tools to assist academic institutions with a variety of different teaching and assessment tasks.

Ever have an issue on your campus where students are required to learn a new piece of technology, but you don’t know how to get them prepared for it? With Maple T.A. 9.5, we have included pre-built content to assist students in learning how to use the Maple T.A. environment, and students can take the new Readiness Test to educate themselves on how to use the system. Tasks such as enabling Java, navigating assignments, grading tests, searching for help, and much more are taught in an interactive setting, and give students the right information they need to become comfortable with Maple T.A.

We haven’t forgotten about instructors and teachers either. We have completely revamped our Instructor Examples to provide educators with a sample question of every single question type in Maple T.A. – that’s over 25 different examples! Instructors are given descriptions, feature lists, and examples for each question type. Additionally, we also created a new Sample Assignment that shows instructors what a typical assignment looks like. They can explore this assignment from both instructor and student viewpoints to test out different options and see what the experience will be like.

Essay questions have been foundational in Maple T.A. for several years now, and Maple T.A. 9.5.makes it even easier to provide feedback for students submitting essays. With the Essay Annotation feature, instructors have the ability to mark-up an essay with comments using a simple drag and drop tool. Using this new tool, your students will be able to see your comments and take note of any issues they had in their writing.

Power outages, automatic updates, computer crashes... we’ve all experienced these unpredictable events, and they can be catastrophic for students trying to meet due dates or if assignments are timed. To help with this Maple T.A. has expanded its Proctor Tools feature.  Instructors can now grant individual students with additional time or date extensions if there are ever any issues.

We’re also giving you a sneak peak at some up-and-coming technology: Gradeable Math Apps. As part of The Möbius Project, you can now embed an interactive Maple worksheet in a Maple T.A. question. Students can move sliders, push buttons, click on plot windows and much more directly inside of a Maple T.A. question. Students are then automatically graded on their interaction with the Math App – just like other question types in Maple T.A.

All these features are all for Maplesoft-hosted and self-hosted users, which also includes all the great stuff from Maple T.A. 9:

  • Adaptive Testing
  • New Question Repository
  • Maple T.A. Cloud
  • Hint Deductions
  • Reworking Assignments
  • MathJax Support
  • Distributed Load Balancing
  • Permanent User Deletion
  • Customizable User Interface
  • Multiple Instructors for a Class
  • And much more!

At Maplesoft, we are extremely excited about Maple T.A. 9.5, and can’t wait for schools all over the world to begin using it!  And as always, we are very interested in hearing from you about your experiences with Maple T.A., as well as any suggestions you have for future releases.

For a question i'm trying to make for my students i need to solve a system of two linear equations, of which the coefficients are determined by predefined random variables. After that i need to assign the solution of the system to two variables. So far i have attempted two approaches, neither of which seem to work:

Solve using inverse matrix:

$oplossing=maple("with(LinearAlgebra):Matrixinverse(Matrix([[1,1],[tan(Pi*alphadeg/180),tan(Pi*betadeg/180)]]))*Vector([$F*sin($gamma),$F*cos($gamma)])");...
