tests that will require them to resolve activities
corresponding to material in mathematics,
language, or environmental knowledge (Amory,
2001; Amory, Naicker, Vincent & Adams,
1999).
• Story Construction. The objective is for the
child to imagine existing and potential
relationships between different parts of reality.
It involves the need to connect facts and
situations with objects and their contexts, and
this requires constructing meanings. Stories give
us a better understanding than simple abstract
presentations (Brown, 2007).
The stories that we present are diverse, and we
believe that this is the natural way to construct,
explore, and solve learning tasks. But they
always require a context. The objects and facts
that will make up the stories need to be put into
context, in this case, therefore, by reference to
the Monfragüe Natural Park. Consequently,
describing the context of a Natural Park
involves re-assessing its role in learning (an
essential activity of environmental education).
• The Use of Mascots (a stork, a boy, a forest
warden, a princess), at different levels of
difficulty, as a means of interaction with the
pupil. They also constitute a highly motivating
element, and provide pupils with clues to
reflection when their cognitive processes fail.
Matching these tasks to the pupils' educational needs
led us to include a series of measures targeted at
specific deficiencies or impairments. To deal with
the case of pupils with a hearing disability, all the
activities and hints to help with their resolution
appear in text on the screen. For the case of visually
impaired pupils, besides the activities and hints
being presented as speech, we designed a tool that
allows them to increase the size of the elements that
appear on the screen. Finally, for the case of pupils
with a mental deficiency or a marked lag in
maturing, the same activities can be presented at one
of three different difficulty levels. In this way, a
priori there is the sensation that all the pupils are
working on the same activity, because the statement
of their activity and the photographs, videos, and
characters making up the story on their screens are
the same. However, the resolution of the activity
will in some cases involve more complex cognitive
strategies and greater previous knowledge than in
other cases. Thus, for example, in the area of
mathematics, and specifically in the content block of
addition and subtraction, in Level I the addition
problem requires operations that do not exceed the
tens and requires no application of the concept of
carrying. In Level II, this same problem will be of a
combinatorial type using up to the thousands and
involving carrying. In Level III, as well as the
application of carrying and increasing the units to
the tens or hundreds of thousands, the problem
statement may be put in the form of a comparison,
which requires a greater capacity of understanding
and decoding than the previous cases.
3 GENERAL CONSIDERATIONS
CONCERNING THE DESIGN
OF THE ACTIVITIES
• The activities included in each thematic block
deal firstly with knowledge of a natural
environment and some of the elements to be
found in it, and secondly with a situation
invented to generate in the child the need to
solve the problem or activity. In as much as the
activity arouses the pupils' curiosity and shows
itself to be relevant and useful in fields that are
of interest to them, it will increase their
willingness to take a real part in carrying it out.
• All the activities are based on problem-solving.
The idea is not for the child to learn a set of
formulas or concepts and be able to reproduce
them faithfully, but rather to be able to apply that
knowledge to real specific cases, that are, in so
far as is possible, close to his or her sociocultural
context (Cuadrado & Fernández, 2006). For
example, it does not interest us whether or not
the child knows the classification of the animals
or plants by memory, but that, after the
presentation of some of these elements which are
presumably going to be familiar, he or she
knows how to classify them by observing and
analyzing their characteristics.
• The level of complexity of the activities included
in each level of each block is increased
progressively. I.e., we work on some concept in
the first activities. After the resolution of these,
we assume that this concept has been assimilated
and propose activities that work on a new
concept related to the former one. In this way,
besides progress in the learning process, we try
to establish conceptual relationships between
elements of the content being presented and to
show their continuity. For example, we first
approach addition without carrying, and then
later progress to addition with carrying. Or we
first work on multiplication by a single figure, to
later increase the number of figures and
