Post author By Aida Alsina
Post date September 9, 2025

Hybrid learning, also known as blended learning, is an educational approach that combines traditional face-to-face instruction with digital, online components. Instead of treating online and offline learning as separate modes, hybrid learning integrates both in a coordinated and intentional way. The goal is not simply to alternate between classroom and remote activities, but to design a cohesive experience that leverages the strengths of each environment—flexibility, accessibility, interaction, and personal connection. This model has gained significant traction in recent years, especially in math education, where abstract concepts and diverse learning needs benefit from varied modes of engagement.

Hybrid learning is reshaping how we teach and learn math. By blending digital tools with in-person instruction, educators can offer more personalized, effective, and engaging learning experiences.

This approach doesn’t replace traditional methods: it enhances them. It respects the emotional and cognitive aspects of learning and responds to the reality of modern classrooms, where students have diverse learning paces, styles, and circumstances.

Blended learning is not a trend but a pedagogical shift that bridges accessibility, adaptability, and human connection.

The Power of Combining Online and Offline Math Instruction

Blended learning in math education creates a synergy that neither modality can achieve alone. As math educators adapt to evolving student needs and technological possibilities, this combined model offers:

Flexibility: Students can access digital resources anytime, which is particularly helpful for review or reinforcement outside the classroom.
Interactivity: Online tools bring math concepts to life through animations, simulations, and interactive problem-solving platforms.
Human Connection: Face-to-face instruction fosters real-time discussion, emotional support, and immediate feedback.
Scalability: Educators can manage large or diverse groups more efficiently, offering tailored support where needed.

In math, where abstract concepts often require iterative exploration, hybrid learning empowers both guided instruction and independent thinking. It accommodates repetition, variation, and collaborative exchange, all crucial for deep understanding. By combining the immediacy of in-person learning with the accessibility of online math teaching, educators can truly transform their practice.

Balance Between Structure and Autonomy in Hybrid Learning

One of the central strengths of hybrid learning is its ability to balance learning framework and autonomy. Math learning demands both: structured pathways to introduce and build skills progressively, and autonomy to foster individual exploration, confidence, and critical thinking. Blended learning strategies provide the framework for this balance, supporting both consistency and creativity in math classrooms.

Online: Providing Structure and Individual Pacing

Online environments offer a structured framework for learning. Through curated modules, step-by-step explanations, and automated feedback, students gain clarity and consistency. The self-paced nature of online platforms allows students to revisit concepts, practice at their own rhythm, and receive immediate guidance, which is especially valuable for mastering foundational skills.

Tools like WirisQuizzes, a platform designed specifically for math and STEM assessments, enhance this experience by offering dynamic, auto-corrected questions with random variables. This not only provides individualized practice opportunities but also ensures that students engage actively with the material rather than passively memorizing answers. Online math teaching empowers learners by offering them control over their pace and focus areas, reinforcing competence and motivation.

Offline: Promoting Dialogue and Deeper Reasoning

Offline, classroom-based instruction adds the relational and spontaneous aspects of learning. In-person sessions encourage students to articulate their reasoning, ask questions, and collaborate on complex problems. Teachers can detect misunderstandings in real time and adapt explanations. These interactions develop mathematical communication skills and help students connect theory with practice. This live component of hybrid learning ensures that math remains a social, responsive, and human-centered discipline.

Together, these modalities reinforce each other. Structure without autonomy may feel rigid; autonomy without structure may lack direction. Hybrid learning aligns both.

Visual and Symbolic Thinking

Math is both visual and symbolic. Hybrid learning supports this duality by using digital tools to represent abstract ideas and classroom environments to interpret and discuss them.

Online platforms like WirisQuizzes or Learning Lemur (our intuitive math platform integrated with Google Classroom that provides customizable quizzes, automatic grading, and personalized feedback) can visualize functions, geometric transformations, or algebraic manipulations interactively. These representations complement traditional symbolic work and help learners form mental models. In-person settings then provide the space to reflect on and interpret these representations with peers and educators, solidifying understanding.

school learning

By moving fluidly between visualizations online and symbolic manipulation offline (and vice versa), students strengthen their conceptual grasp. This kind of dynamic interplay is a key benefit of hybrid learning, enabling learners to connect different forms of mathematical representation more effectively.

Real-World Applications of Hybrid Learning in Math

Hybrid learning is not just a theoretical framework, it is being put into practice across a wide variety of educational settings. From urban schools to rural learning centers, educators are designing innovative ways to integrate digital and face-to-face instruction in their math classrooms. These practical applications demonstrate how blended learning strategies can meet diverse educational needs while maintaining quality and engagement.

Among the many institutions that already apply the hybrid learning system, we can find 21K School (United Kingdom), Harvard University (USA), Massachusetts Institute of Technology (USA), and public schools in Singapur.

Use Cases from Classrooms Worldwide

A high school teacher flips the classroom: students watch instructional videos and complete guided exercises at home, while class time is used for collaborative problem-solving.
A university professor alternates between digital assessments and in-person workshops, combining online scalability with live, hands-on support.
A community center in a low-connectivity area uses downloaded interactive materials during the week and organizes weekend math clubs with volunteer educators.

These real-world models show how hybrid learning can be tailored to different contexts, always seeking to optimize both access and engagement.

This is a classic calculus problem that, as we will see, requires the use of both derivatives and integrals. Don’t worry; we’ll break it down into three clear and simple steps. Let’s get to it!

How to Find the Equation of the Tangent Line?

Before starting with the calculations, let’s visualize the problem. Below, you’ll see a graph illustrating the parabola y=x² and the tangent line at the point (a, a²), where a>0. In this graph, we can see how the tangent line touches the curve of the parabola at a single point without crossing it.

Now, to proceed, we first need to find the equation of the tangent line at that specific point. Since the tangent touches the parabola at point (a, a²), we need to determine both its slope and its equation.

This is where the derivatives come into play. The slope of the tangent at any point on the parabola is given by the derivative of the function y=x². We start by calculating the derivative: dy/dx=2x

This means that the slope of the tangent at any point on the parabola is 2x. To find the slope at the tangent point (a, a²), we substitute in the derivative:

Therefore, the slope of the tangent line at point (a, a²) is 2a.

Now that we have the slope, we can write the equation of the tangent line using the formula for the line in its form:

y – y₀ = m (x – x₀)

Where m is the slope of the line, and (x₀ , y₀) is the point through which the line passes. In our case, the point of tangency is (a, a²), and the slope is 2a, so we substitute these values in the formula for the line:

y – a² = 2a (x-a)

y – a² = 2ax – 2a²

y = 2ax – a²

So, the equation of the tangent line at the point (a, a²) is:

y = 2ax – a²

Find the Intersection Points

Now that we have the equation of the tangent, we need to find the points of intersection between this tangent and the x-axis, that is, when y=0. This will allow us to determine the limits of the region whose area we want to calculate.

The area to be calculated is marked in orange in the graph below.

Substituting y=0 in the tangent equation and solving for x we obtain:

0= 2ax – a²

2ax = a²

x = a/2

So the tangent cuts the x-axis at point

P=(a/2, 0 )

Calculate the Area Between the Parabola, the Tangent and the X-axis

Once we have the equation of the tangent and we know the points of intersection, we can proceed to calculate the area of the region bounded by the parabola, the tangent and the x-axis. For this, we use the definite integral, which allows us to find the area between two curves.

The area we want to calculate is obtained by subtracting two regions. In the first graph, you can see the total region we are interested in. However, part of this area is specifically delimited in the second graph, which we must subtract to be left with only the part we are looking for.

Let us calculate both integrals:

a) Integral of graph 1:

definite integral of x squared from 0 to a. It equals the integral from 0 to a of x squared dx, which is equal to x cubed over 3 evaluated from 0 to a, resulting in a cubed over 3.

b) Integral of graph 2:

Now that we have solved all the integrals, we subtract the results to obtain the total area:

In conclusion, the area of the region bounded by the parabola y = x², the tangent y = 2ax – a² and the x-axis, is:

a sup 3 / 12

Therefore, option c is the correct answer

And so we come to the end of this fascinating problem! If you enjoyed this analysis or found it useful to better understand the solving process, feel free to share it with other math enthusiasts!

Now we challenge you: do you dare to calculate the area formed by the curve y = x³ and its tangent at the point (1,1)? Share your solution or your ideas in the comments. We’d love to hear your approach!

Towers of Hanoi: A Math and Programming Challenge

Towers of Hanoi: A Math and Programming Challenge

The Towers of Hanoi is one of the most iconic puzzles in the field of mathematics and computer science. With its simple structure and transparent rules, this problem has captivated mathematicians and amateurs alike, making it an intriguing challenge since its creation.

According to the legend, the Towers of Hanoi were conceived by a group of monks in an ancient temple in India. In the center of this temple, three golden pillars stood, upon which rested 64 disks of various sizes, arranged in the first pillar in an orderly fashion: the largest disk at the base, with progressively smaller disks stacked on top, until reaching the smallest disk, placed at the top.

The monks’ objective was to move all the disks from the first pillar to the third, using the central pillar as an auxiliary. To accomplish this task, they had to follow a strict set of rules:

Only one disk can be moved at a time.
A disc can never be placed on top of a smaller disc.

Legend says that when all the disks were correctly transferred to the last pillar, the world would come to an end. However, how close is the end of the world, really? How long would it take to complete this challenge?

This challenge was officially introduced by the French mathematician Édouard Lucas in 1883 as part of his research in number theory and quickly became a popular problem.

Next, we will analyze the solution of this problem from a mathematical perspective, breaking down its key principles and explore how it transforms into an interesting programming challenge.

Recursion as a Solution to the Puzzle

The challenge of the Towers of Hanoi is not only in moving the disks from one pillar to another following the strict rules but also in calculating how many moves are needed to solve the problem of moving n disks from the origin pillar to the destination pillar.

The most efficient way to approach this problem is through recursion, a fundamental technique in programming. Recursion allows the problem to be divided into smaller subproblems, where the solution of each subproblem leads to the solution of the original problem.

In the case of the Towers of Hanoi, recursion applies naturally, and we can divide the problem of moving n disks into three steps:

Move the first n – 1 disks from the origin pillar to the auxiliary pillar, using the destination pillar as the auxiliary.
Move the largest disc (the disc n) from the origin pillar to the destination pillar.
Move the n – 1 disks from the auxiliary pillar to the destination pillar, using the origin pillar as an auxiliary.

We can repeat this pattern recursively, reducing the number of discs with every step until we reach a base case where only one disk remains, which we just directly move.

In mathematical terms, the minimum number of moves to solve the problem with n disks equals the number of moves needed to solve it for n – 1 disks, plus one to move the largest disk, plus the number of moves needed to solve it for n – 1 disks again. This formula yields the result:

TH( n ) = TH( n – 1 ) + 1 + TH( n – 1 ) = 2TH( n – 1 ) + 1

Where TH( n ) represents the number of moves needed to solve the problem with n disks.

From the above formula, we will substitute each TH( i ) by its corresponding expression until we reach TH( 1 ) . Then, we will replace TH( 1 ) by 1, since, with only one disc, it is possible to move it directly to the destination pillar, which justifies that the minimum number of moves in this case is 1.

Let’s see the expression developed:

We first substitute TH( n – 1 ), and we obtain:

TH( n ) = 2TH( n – 1 ) + 1

TH( n ) = 2( 2TH( n – 2 ) + 1 ) + 1 = 2²TH( n – 2 ) + 3

Now we substitute TH( n – 2 ):

TH( n ) = 2²TH( n – 2 ) + 3

TH( n ) = 2²( 2TH( n – 3 ) + 1 ) + 3 = 2³TH( n – 3 ) + 7

If we continue substituting in this way, we will arrive at a general formula:

TH( n ) = 2^k TH( n – k ) + (2^k – 1)

Where k is the number of steps backward in the recursion.

For k = n – 1 we arrive at TH( 1 ), the base case:

TH( n ) = 2²TH( n – 2 ) + 3

We know that TH( 1 ) = 1, then we obtain:

TH( n ) = 2^{n – 1} · 1 + ( 2^{n – 1} – 1 ) = 2ⁿ – 1

We have shown that the number of moves needed to solve the Towers of Hanoi with n disks is:

TH( n ) = 2ⁿ – 1

Solving the Puzzle Using Mathematical Induction

Another way to approach the solution to the Towers of Hanoi puzzle is to use mathematical induction, a technique used to prove that a statement is true for all natural numbers, based on two fundamental steps: the base case and the inductive step.

In this case, the goal is to show that to move disks from the first pillar to the third pillar, 2ⁿ – 1 moves are required. Let’s break this process down with a demonstration by induction.

Base case:

Suppose we have only one disk. In this scenario, it is clear that only one move is needed to move the disk from the source abutment to the target abutment. That is, for n = 1, the number of moves required is 2¹ – 1 = 1, which is true.

Inductive step:

Now, suppose that the statement is true for n = k, i.e., that to move k disks requires 2^k – 1 moves. What we must prove is that the statement is also true for n = k + 1.

To move k + 1 disks, we first need to move the upper disks from the origin pillar to the auxiliary pillar, using the destination pillar as an auxiliary. According to our inductive hypothesis, this will take 2^k – 1 moves.

Next, we move the larger disk (the disk k + 1) from the origin pillar to the destination pillar, which requires just 1 move.

Finally, we move the k disks from the auxiliary pillar to the destination pillar, using the origin pillar as an auxiliary, which will also take 2^k – 1 moves, according to our inductive hypothesis.

Therefore, the total number of moves required to move k + 1 disks is:

(2^k – 1) + 1 + (2^k – 1) = 2^k+1 – 1

Thus, we have shown that if the statement is true for n = k, it is also true for n = k + 1.

As we have observed, it is true for 1. By mathematical induction, we can conclude that for n disks, the minimum number of necessary moves is 2ⁿ – 1.

Going back to the legend, if the monks were extremely fast and could move a disk in just one second, we could calculate how long it would take to complete the challenge with 64 disks. According to the formula, the total number of moves would be 2⁶⁴ – 1, approximately 18.4 quintillion moves. With each of these taking just 1 second, this gives us 18.4 quintillion seconds. Converting these into years, we get that the total time would be approximately 581.4 billion years. So, if the legend turned out to be true, the end of the world would still be a long way away!

CalcMe formula We note that the function describing the number of moves needed to solve the Towers of Hanoi is exponential, meaning that it grows rapidly as we increase the number of disks. In the following graph, we can visually see how this function spikes, clearly illustrating the exponential growth.

This visual support allows us to confirm, once again, that completing the challenge with 64 discs would take an extraordinary amount of time.

AI in Mathematics: The Revolution in Scientific Writing

Post author By Aida Alsina
Post date May 6, 2025

Artificial Intelligence (AI) is a field of computer science that seeks to develop systems able to perform tasks that traditionally require human intelligence, such as logical reasoning, problem solving, and learning. Based on advanced algorithms and machine learning models, AI can analyze large volumes of data, identify complex patterns and adapt autonomously to new contexts.

In mathematics, these capabilities are transforming the way knowledge is generated, verified, and communicated. From automating demonstrations to generating detailed explanations, AI is facilitating the work of researchers, teachers, and students. In addition, its ability to process natural language is improving the writing of mathematical papers, making texts more accessible, accurate and structured.

In this article, we will explore how AI in math is revolutionizing mathematical writing and how Wiris’ tools are part of this advancement.

The Role of AI in math and the Creation and Editing of Mathematical Content

Writing scientific papers in mathematics has always been a challenge due to the complexity of their notations and symbols. Traditionally, mathematicians have relied on handwriting or the use of complex typesetting languages. However, with the advent of AI, the process of creating and editing scientific documents has evolved exponentially.

Artificial intelligence has brought multiple benefits to the writing of mathematical papers, facilitating both the writing and the editing and publication of academic papers. Below are some of the main ways in which AI is impacting this area.

Handwriting recognition

One of the most significant advances has been the development of systems capable of interpreting and digitizing handwritten notes. Traditionally, mathematicians wrote their equations and proofs on paper, which was time-consuming if they needed to transcribe them into a digital format. With AI-based handwriting recognition tools, such as those built into MathType, it is now possible to directly handwrite equations into our touch devices and automatically convert them into editable digital text.

This not only saves time but also reduces transcription errors and allows you to work more efficiently. In addition, this type of technology is especially useful for students and teachers, as it facilitates the conversion of notes into organized documents without the need for manual typing.

Formula automation

In the creation of mathematical articles, writing formulas accurately is essential. Traditionally, this required specialized tools that, while powerful, could be complex and demanded a deep understanding of their syntax and structure, such as LaTex.

Advancements in technology have enabled the development of tools like MathType, which simplify equation writing without the need for coding. Instead of memorizing commands and code structures, users can simply enter their formulas through an intuitive graphical interface. This democratizes access to mathematical writing, allowing more people, regardless of their technical expertise, to create high-quality mathematical documents.

Another key aspect is the automatic correction of errors in equations. AI in math can identify inconsistencies in formula writing and suggest real-time corrections, preventing mistakes that could compromise the validity of an academic paper.

Optimization of editing

Another benefit that AI has brought is the optimization of the editing of mathematical documents. In the past, mathematicians and scientists had to manually check their documents for errors in equations, notation and text structure. Today, there are AI algorithms embedded in editing programs that can analyze the consistency of mathematical expressions, suggest improvements in writing and detect inconsistencies.

AI-based writing assistants, such as those integrated into advanced text processors, can help improve the clarity and readability of mathematical articles. In addition, they provide stylistic recommendations to give the paper a logical and easy-to-follow structure, which is crucial in academic paper writing.

The integration of AI into mathematical writing is not just an evolution but a revolution that is transforming the way we create, edit, and share scientific knowledge. Tools like Wiris, with their powerful capabilities, are making mathematical writing more accessible, efficient, and error-free. As these technologies continue to advance, they will further bridge the gap between human intuition and machine accuracy, making the work of researchers, teachers, and students alike easier.

Wiris in the Classroom: Learn and Practice with Unlimited Exercises

Post author By Aida Alsina
Post date April 16, 2025

Learning mathematics requires more than just understanding theories: the key to mastering complex concepts and honing skills lies in continuous practice. However, traditional methods often limit the learning process: once the student has solved a problem, the challenge disappears, and exams often repeat the same questions, thus losing their value as an assessment tool. Imagine having the possibility to generate unlimited exercises with random variables, adapted to the needs of each student. With Wiris, this is now possible.

In addition, it has an automatic correction functionality which means that while the exercise is being generated, the answer is calculated simultaneously. This allows instant feedback, making it easier to learn and correct mistakes immediately.
For teachers, this tool offers a key advantage: the possibility of generating an infinite number of exercises, with each one being unique. In this way, teachers can create varied and personalized learning experiences, ensuring that students face new challenges every time they practice.

For their part, students enjoy constant practice which allows them to reinforce their skills without the worry of repeating the same exercises. In addition, this ability to generate unlimited exercises gives them excellent preparation for exams.

Practical example: Solving a system of linear equations

To illustrate how this tool works and how it can be used in the classroom, we will focus on solving systems of linear equations. We chose these types of problems because they represent a common mathematical challenge faced by all students and offer the possibility to explore different problem-solving methods. In addition, systems of equations can have various characteristics, such as being compatible, incompatible, or indeterminate, allowing students to work with a wide range of situations.

Let us imagine that we have the following system of linear equations with three unknowns:

We are going to solve it using Gauss’s Method. The first step is to write the system in the form of an augmented matrix:

Now, we will apply elementary operations to reduce the matrix to its row echelon form.

Therefore, we obtain:

From equation 3 of the system, we find the variable z:

Unlimited generation of systems of linear equations with random variables

Now that we have solved this system, for further practice, we would like to be able to generate new systems of equations of the same form but with random values.

These systems would take the following form:

Below, we will show you a code example to implement this functionality and generate given random systems of equations. With Wiris, it is totally possible!

r() := random(-4,4)

sol = [r() with i in 1..3]

[a,b,c] = sol

repeat

A = [[r() with i in 1..3] with j in 1..3]

until determinant (A) != 0

b = A * sol

ec = {}

for i in 1..3 do

ecaux = A.i * [x,y,z]

ec = append(ec, ecaux = b.i)

end

{ec1, ec2, ec3} = ec

r() := random(-4,4): This function generates a random number between -4 and 4.

sol = [r() with i in 1..3]: Here, three random values are generated that will represent the solutions of the system of equations.

[a,b,c] = sol: The generated values are assigned to the unknowns of the system.

repeat…until determinant(A) != 0: This block ensures that the coefficient matrix A is invertible (i.e., its determinant is not zero), which guarantees the system has a unique solution.

b = A * sol: The result vector b is calculated by multiplying the coefficient matrix A by the solutions sol

for i in 1..3 do: In this cycle, the three equations are generated, using each of the rows of the matrix A and the solutions sol.

{ec1, ec2, ec3} = ec: Finally, the three generated equations are stored in the variables ec1, ec2, and ec3, ready to be used in new exercises.

Using WirisQuizzes and implementing this code as a question, we can obtain the following results:

Reloading another system with the symbol “=” generates a new set of equations, as shown below:

What is the Birthday Paradox?

Post author By Aida Alsina
Post date April 8, 2025

The Fascinating Probability of Sharing a Date

The birthday paradox is a mathematical concept that invites us to challenge our intuition. A paradox, in essence, is a statement or result that, although seemingly contradictory or contrary to common logic, proves to be true when analyzed closely. In the case of the birthday paradox, the scenario is simple but puzzling: how many people must be in a room for the probability of at least two sharing the same birthday to be greater than 50%?

The result will be surprisingly low, but do you dare to answer before you continue reading to reveal the answer?

The most intuitive way to approach the paradox would be to think that it takes at least 183 people, half the days of the year, for the probability of two people sharing the same birthday to be greater than 50%. However, the reality is very different.

To understand how this probability is calculated, let us recall that the basic formula of any probability consists of dividing the favorable cases by the total cases.

In this case, rather than calculating the probability of a coincidence directly, it is easier to first calculate the probability that no two people share a birthday. After determining this probability, subtracting it from 1 (that is, calculating the complement) gives the probability that at least two people share a birthday.

To calculate the probability that no two people share a birthday, we will proceed constructively, evaluating scenario by scenario.

If there is only one person in a room, there is no chance that they will share their birthday with someone else since no other people are present. Therefore, the probability that their birthday is unique is 100%, i.e., 365/365.
Now, if a second person comes in, the probability that their birthday will be different from the first person’s is 364/365, since there are only 364 days remaining in which they can be born to avoid a coincidence.
If a third person is added, the probability that their birthday does not match anyone else’s is 363/365 since there are now two busy days.

Therefore, for n people, all the above conditions must be met simultaneously: that the second person does not share a birthday with the first, that the third person does not share a birthday with the previous two, and so on. This implies that the probability that none of the n people share the same birthday is the product of the individual probabilities:

And finally, we obtain:

Analyzing probabilities for different values of n

Let us examine the results for different values of n:

For n=10 we obtain that P (at least one coincidence) = 11,61%

CalcMe representation of the equation

This calculation has been created using CalcMe

For n=15 we obtain that P (at least one coincidence) = 25,03%
For n=23 we obtain that P (at least one coincidence) = 50,05%
For n=50 we obtain that P (at least one coincidence) = 96,53%
For n=60 we obtain that P (at least one coincidence) = 99,22%

As we can see from the examples above, to achieve a probability of more than 50%, only 23 people in the same room are needed. This result may seem surprising, but it makes sense if we consider that with 23 people, 253 different pairs can be formed, and each of these pairs represents a chance for two people to share the same birthday. Even more surprising is that to have a probability greater than 99%, only 60 people are needed, demonstrating how the number of possible combinations grows rapidly with every new person added.

This is the graph of the probability distribution:

Graph showing the probability of two people sharing a birthday, with the number of people on the X-axis and the probability on the Y-axis, expressed as a percentage.

In contrast, if instead of calculating the probability of coincidence between any pair of people we consider the probability that someone in a room of n people (excluding you) specifically shares your birthday, the calculation is different. This probability is given by:

For n = 22, this probability is about 0.059 (5.9%), which is quite low. In fact, there would need to be at least 253 people in the room for this probability to exceed 50%.

The birthday paradox is a fascinating reminder of how our intuition can fail when confronted with mathematical logic.

Now that you know the birthday paradox and its key concepts, can you calculate the probability that exactly k people within a group of n people share their birthday?
