An old idea was to stage a school situation in university by the face to face system, a new idea is to stage as the school situation in college, but in an online system designed in terms of didactic engineering, to practices through numerical methods in MOODLE (Module object- Oriented Dynamic Learning Environment) platform, the theoretical aspect that will support the mathematical object, are the basic ideas of the theory of e- learning  (from the English phrase we understand as learning).
The central proposal of this investigation is to highlight that in the teaching-learning process traditionally used in the in-person system (face to face), radically changed from the delivered content and necessary practice for learning a system online by MOODLE platform.
Then aims in this paper the design activities, according to the theory and practice of online learning and testing every one of the methods that make up a university course on Numerical Methods.
In particular consider the case of the gridding of a randomized data set; the mathematical object considered in this report will approach by the method of segmental cubic spline fit .
So we intend to prove that the staging of content and practices (activities) of numerical methods, appropriate to the learning styles proposed in the theory and practice of online learning , which can achieve significant learning.
The design strategy practices numerical modeling will support the concepts of the three (or four) basic schools of learning, ie, in the Behavioral Schools, Cognitivist, Constructivist and Humanist.
The content in conjunction with practices that correspond to numeric object considered in this work consist of a good description of the mathematical development of splines available in a document, other content element is a presentation where an example of the application of the method is used a case study, a third element is an interactive program that solves numerically, all integrated on the platform and practices are defined by the activities that are available on MOODLE, which may consist of questionnaires, crosswords, letters, memory games, problems involving a process, creating solutions for computer and other activities and resources.
The experiment was conducted with students from a public university in the state of Jalisco, Mexico. The test results of a functioning online material will be published in a later article to this ongoing investigation.
