Assessment of the experience

POSITIVES aspects

They thought it was POSITIVE

Lack of time to interact with the material in advance.

They brought consultations about exercisestested with GeoGebra at their homes.

introducing hypermedial educational material

At the First-Year Course of Mathematics A of the School of Engineering at the National University of La Plata.

Use of a computer tool for mathematical work.

Understanding three-dimensional mathematical objects.

Familiarization with GeoGebra applets.

Number of devices available, time, and attitudinal aspects.

Focusing on improvement variables + barriers found + work with mobile devices.

Discussion of multiple strategies.

Based on the contents of the original theoretical and practical guide developed by teachers of the course in which the following topics are dealt with: vectors; straight lines in space; and planes. (eXeLearning program)

a) Visualizing three-dimensional-space objects.b) Confirming solutions through the use of GeoGebra applets.c) Acquiring a better understanding of contents in the unit dealt with.

a) The additional time that they had to dedicate to using HEM.b) Di�culties to learn the GeoGebra program.c) Shortage of computers.d) Having to bring their own laptops.

RESULTS

CONCLUSIONS

Survey with 6 Mathematics A commissions with three parts:

Survey with two parts:

Participant observation, semi-structured interview to teachers and analysis of examsQualitative methodological techniques

1st Personal data 2nd Technology use and access 3rd Attitudes toward ICTs .

1st The same as the 3rd above 2nd Easiness and di�culty of the topics covered.

1st general observation during classes

2nd general observation 1st they all dealt with HEM 2nd HEM and other traditional materials

EXAMcontrol group Experiment group

Students show a more exploratory attitude than that shown when working with printed material, pencil and paper GeoGebra applets made it possible to test solutions and the Use of multiple strategies taking advantage of di�erent previously acquired knowledge items.
