Big data in education has huge potential to improve learning

The modern sage Jose Ferreira, a pioneer in the union of education and technology, once proclaimed: “Big data in education has huge potential to improve learning materials.” At first glance, these words seem to belong to the age of algorithms and machines, yet beneath them beats an ancient truth: that the more deeply we understand the learner, the more wisely we may teach. Ferreira speaks as one who peers into the future, yet his wisdom belongs to all ages—the belief that knowledge, when guided by insight and compassion, can transform not only the classroom, but the very soul of learning itself.

In the world of old, a teacher might gaze upon the faces of a few pupils and learn their struggles by heart—the flicker of confusion in an eye, the spark of curiosity in a question. But as civilizations grew, and millions entered the halls of learning, this personal bond became harder to preserve. The age of big data—the gathering of patterns, behaviors, and unseen connections—offers, in Ferreira’s vision, a way to reclaim that lost intimacy through the lens of knowledge itself. It is the attempt to see every learner once more—not as a number, but as a mind, a soul, a unique constellation of understanding.

To grasp the full force of Ferreira’s wisdom, imagine the story of Salman Khan, founder of Khan Academy, who began by tutoring his cousin with simple online videos. As thousands of students began to watch, data flowed like a new river of insight. Each click, each pause, each repeated video became a message from the learner—a whisper revealing where confusion lived and where comprehension bloomed. By listening to this data, teachers could adapt, refine, and illuminate. What once took years of trial and error could now be known within moments. The learning materials themselves—lessons, exercises, explanations—could evolve to meet the living needs of the student. In this, we see the spirit of Ferreira’s words brought to life.

And yet, there is a deeper current beneath his claim. For big data alone is not wisdom; it is the raw ore from which wisdom must be forged. The ancients once said that knowledge without understanding is a sword without a hand to wield it. So too with data: it must be shaped by empathy, by a moral compass, by the sacred purpose of education—to awaken, not to control. Ferreira does not praise the power of machines for their own sake; he calls upon humanity to wield that power with vision. The potential of data lies not in surveillance, but in service; not in the cold analysis of numbers, but in the warm illumination of minds.

In this, the story of the Renaissance offers a mirror. When the printing press spread across Europe, it was feared as a tool of chaos, a force that would flood the world with unchecked information. Yet from that flood arose a new dawn of learning—books reached the poor, ideas crossed borders, and truth began to shine more freely than ever before. So it may be with big data in our age. What seems mechanical and vast may yet become the forge of a new enlightenment—if guided by wisdom, compassion, and the eternal love of learning.

But Ferreira’s warning is subtle: potential is not destiny. Just as fire may warm or consume, big data may enlighten or enslave. If used only to rank, to compare, to reduce the human mind to a metric, it will poison the spirit of education. But if used to reveal the pathways of growth, to tailor learning materials to each soul’s rhythm, it will become a divine tool—one that restores the lost art of understanding each student as a world unto themselves. The task of educators, then, is to ensure that technology remains a servant of wisdom, not its master.

The lesson for us is thus both ancient and new: know the learner, and you will know how to teach. Whether through conversation or through data, through ink or through code, the heart of education remains unchanged—to see the unseen, to nurture the spark of curiosity, to guide the mind toward truth. We must embrace innovation, yet anchor it in human purpose. Let every teacher learn not to fear the new, but to shape it; let every student remember that data is not their destiny, but their mirror—a reflection of the infinite capacity to grow.

And so, as the ancients once taught the art of the lyre, and the monks once preserved the light of knowledge in their manuscripts, so must we now learn to play this new instrument of the modern age. Big data, when joined with compassion, becomes not a machine’s tool, but a philosopher’s ally. Let us wield it wisely—so that the materials of learning may not only improve, but truly awaken the hearts and minds of generations to come. For in the marriage of technology and education, guided by the wisdom of the human spirit, lies the next great renaissance of the soul.
