Abstract:

The Information and Communication Technologies, propose new scenarios that require a revision of the classical teaching model, since both the methodologies and the way to access and acquire the knowledge and resources used are affected by this technology. The traditional teaching where class space is a classroom equipped with a blackboard is present in most of the schools. However, more and more teachers are going to meet students who belong to a new generation, a digital generation, in which information and learning are no longer confined to the physical classroom, nor is it offered exclusively by the teacher, which implies changing the educational model by designing appropriate learning environments. Today's students have grown immersed in technology, where computers, tablets and cell phones, etc., are ways in which they interact with their world, so they need study material that fits the way they learn.

In accordance with the foregoing, a multimedia book on the topic of probability distributions was developed. Random variables can be classified as discrete and continuous. A probability mass function and a probability distribution function are two ways to characterize a distribution for a discrete random variable. They are equivalent in the sense that knowledge of one or the other completely specifies the random variable. The corresponding functions for a continuous random variable are the probability distribution function and the probability density.

Within this context, the didactic material developed from the theme of graphics, according to these ideas, are digital textbooks integrated into appropriate virtual environments; since a digital book is a publication whose support is an electronic file that can be stored in different digital media and allows the incorporation of interactive and multimedia elements.

The aim of this material is that students will no longer be limited to static images that illustrate traditional texts, but can now immerse themselves in an image with interactive subtitles, rotate an object in 3D or make an answer come alive in the review of a chapter.

You can flip through a book by just sliding a finger on the screen. They can also highlight text, take notes, search for content and find definitions in a glossary very easily. In addition, they can take them wherever they go, which will allow students not only to learn within the walls of the classroom but also in the virtual space that these books constitute.

The digital textbook of presentation of the developed information contemplates that each chapter indicates prerequisites, learning objectives, written development of the subject, videos with the explanation, interactive galleries, calculators developed with Geogebra, Interactive images, interactive exercises, and self-correcting questions.
