Managing Digital Resources in the Classroom – Webinar


Recently I had the pleasure of attending a webinar at on the topic of “Managing Digital Resources in the Classroom”, held by Beatriz Arnillas of Houston ISD. A wonderful presentation on how schools and districts can make it easier for teachers to find and use digital resources that engage students and promote learning. The recording of the webinar is now available in the edchatinteractive archives.

There were about 20 attendees and I was very excited to join the discussion. This topic has intrigued me for a long time so I grabbed the chance to hear how one of the largest districts in America has made the transition to using digital resources in their schools.

What have I learned?

Beatriz brought up a number of important points regarding the challenges of implementing digital resources into the curriculum. Some of them are:

Security and Privacy is Paramount

A number of regulations such as FERPA and COPPA have been put in place to ensure the adequate processing, storage and use of students’ information. Many software vendors see these strict regulations as a challenge to overcome, however we at The Mathist welcome the existence of such well defined and formalized regulatory acts.

No matter how strict – rules are rules – and if they are clearly defined, they are easy to follow. After all, it is in our common interest that the students are treated with respect and care, for our future ultimately depends on the generations we strive to educate today.

LTI – Centralized Authentication and Authorization

Schools usually work with multiple software vendors and use many software products. Beatriz pointed out that it is practically infeasible to provision and manage many sets of credentials for each student and for each software product. Human errors are common, and the teacher spends the lions share of their time in the classroom managing students’ accounts and making sure that everyone has access.

This problem can be solved by using LTI-enabled tools. LTI stands for “Learning Tools Interoperability”, and it is a standard which defines how vendor software can interact with the schools Learning Management System (LMS).

In short: the LMS system holds all the students’ roster information. And the third-party learning tool may need a subset of this information to properly function. LTI defines the procedures and ways of communication between the third-party learning tool and the LMS.

The LTI specification is wide in scope. Support includes use-cases from a simple Single Sign-On (SSO) to sophisticated reporting of learning outcomes. It is being actively maintained by the IMS Global organization.

Beatriz mentioned that they use Clever as their SSO provider, often using the terms SSO and LTI interchangeably, which also brings me to a point of confusion. Clever has developed a proprietery standard for accessing students’ roster information, whereas the LTI specification is an open standard. What is the relationship between Clever and LTI is a bit blurry, as they appear to support the same use-case. We at The Mathist will have to investigate this further.


Having had the privilege of attending this very informative webinar, I sincerely recommend that anyone interested in EdTech joins one of the sessions at Further I will emphasize that the efforts of digital learning experts such is Beatriz to connect to a wider audience greatly impacts education and the EdTech industry.

The LTI standard is seeing wider and wider adoption by the major software vendors of Learning Management Systems, which is a good thing, as it is one of the most important enabling factors for EdTech innovation.




Life Skills Learned In Math Class


One of the hardest questions for many math teachers to answer in a way that is relevant to students is: “why do I need to know this?”  “For the next course you take”, the easiest answer in many cases, does not answer the question that was usually being asked.

My answers to this question obviously depend on the topic being studied at moment, and I don’t have “good” answers for all topics…  but here is my list of key quantitative life skills I learned directly or indirectly from math class, with

This picture represents the keyboard for the Drawing field when a pencil is selected.


One of the main advantages in The Mathist is keyboard which opens when using the formula field. Unique and recently updated, it is meant to be easy to use and effective. Above the standard QWERTY keyboard, there are two additional rows: one with the numbers and the other with most common mathematical signs. Through this and other formulas mentioned later in the text, you can navigate by arrows on the right. The small button in the bottom left corner offers the possibility to choose between QWERTY and Greek keyboard (lowercase and uppercase).

Inserting a predefined formula

We offer you auto complete feature: start typing the name of what you need and choose the right formula from the drop-down list that will appear. For example, when you type the letter i in the formula field, this list opens up:

Auto complete example

Here we choose the Integral from the list and in spite of the typed letter, the symbol appears:

Here are some examples;

  • Simplify any expression to speed up problem solving,
  • Plot graphs,
  • Evaluate expressions and get approximate values,
  • Solve equations and inequalities (with visual representation),
  • Solve definite and indefinite integrals (with visual representation),
  • Crunch difficult logarithms,
  • Find derivatives and much more…

You can do all of this with just one button: solve-on

Why is this important?

Have you ever worked on a problem, that is easy to understand, but just requires too much number crunching? – So did we!

We understand that learning a million new things every day as a technology or a science student doesn’t leave too much time for crunching math. And yet in most cases you cannot solve anything without it.

We decided create a solution to this problem with the help of cutting-edge technology.

The Mathist allows you to focus on problem solving and not number crunching, so that you achieve better results at things you are interested in!

Feeling Lucky? – Total Probability Theory

Total Probability Screenshot

When Blaise Pascal and Pierre de Fermat studied a problem related to a gambling game they developed what is now widely known as the probability theory.

They were hired by two very rich man, that were interrupted in a middle of a gambling game, to determine in which proportion the stakes should be divided based on the current score.

The formula of total probability is widely used and is very significant in the probability theory. 

The fun fact is that the interest in probability was solely influenced by gambling games throughout the 17. 18.  and 19. century. Only way later was probability studied for theoretical reasons. :)

The Most Beautiful Formula

The famous Euler’s identity is  widely considered the most beautiful formula in all of maths.

For me It is because it binds all of the fundamental mathematical constants in a single,  short and sweet equality.

  • The number e, which is the base of the natural logarithm,
  • The number pi, which represents the ratio between the, circumference and the diameter of a circle
  • The constant i, or the famous imaginary unit, defined as the square root of -1,
  • The constant 0, which is the neutral element for the operation of addition,
  • The constant 1, which is the neutral element for the operation of multiplication.

Thank you, sir Euler! 🙂

The Famous Harmonic Series

The divergence of the harmonic series is the source of many counterintuitive conclusions, such as this one:

Given a collection of identical dominoes, it is clearly possible to stack them at the edge of a table so that they hang over the edge of the table without falling. The fun fact is that one can stack them in such a way to make the overhang arbitrarily large, provided there are enough dominoes. 🙂

The New Autocomplete Feature!

With thie new Autocomplete feature it is now easier than ever to write formulas!

To write a formula just start typing its name and The Mathist will suggest it to you.

Using the Up and Down keys choose the formula from the list and insert it by pressing the Right arrow or the Enter key, or just tap or click on the one you need.

For example: to write the root, start typing: ro… and watch The Mathist narrow the choices with each letter. 🙂

To cancel the autocomplete, press Escape or the Left arrow.
