1. On the
quasi-extended addition for exploded real numbers
István Szalay
Abstract: In teaching
primary teacher trainees, an awareness of the characteristic features,
especially commutativity and associativity
of basic operations play an important role. Owing to a deeply set automatism rooted
in their primary and secondary education, teacher trainees think that such
characteristics of addition are so trivial that they do not need to be proved.
It does not cause a difficulty in applying mathematical knowledge in everyday
situations but primary teachers must have a deeper insight. That is why it is
reasonable to show these characteristic features to primary teacher trainees in
a different algebraic structure. An example for that could be the algebra of
vectors. In this paper the algebraic structure of exploded numbers containing
the set of real numbers as a subset is selected as an example. With the help of
super-operations (super-addition, super-multiplication, super-subtraction and
super-division) introduced for exploded numbers, we try to extend addition for exploded numbers as well. The question of the method of
extension and the examination of the characteristics of the extended addition
arises. While seeking for the answer, surprising facts emerge, such as the
phenomenon that each real number will have one and only one addition
incompetent pair among exploded numbers. In this paper we introduce the
quasi-extended addition for exploded real numbers which is essentially
different from super - addition. On the other hand, the quasi-extended addition
is the (traditional) addition for real numbers. Moreover, we investigate some
properties (for example commutativity, associativity) of quasi-extended addition. Finally, we find
some similarity between the countable infinity and the exploded of 1. The
quasi-extension of addition is useful for students to observe different kinds
of algebraic properties, too.

3. Elementary Preservice Teachers’
Change
Alenka Lipovec, Polonca Pangrčič
Abstract: In the last two
decades investigation of teachers’ beliefs and conceptions and teachers‘possibilities for change has been one of the
points of emphasis in mathematics education. We propose the concept and design
of an intervention program including five stakeholders on the basis of a
teacher–student–parent–preservice teacher–teacher
educator relation. The main idea is comprised of reversed roles in teaching and
learning process i.e. elementary school preservice
teachers should adopt beliefs and conceptions from the mathematically promising
students (age 6-12). The program is defined by 10 relationships among
stakeholders and was evaluated from various viewpoints. In this paper, we
highlight the effect on the preservice teachers’
competencies during the longitudinal study. We have focused on the gap between
desired and achieved competences as viewed by the preservice
teachers. Overall results speak in favour of
presented approach.

5. Project
method, as one of the basic methods of Environmental Education
Noémi Szállassy
Abstract: Our aim was to
present in this paper the one of the most important methods of environmental
education, the project method. We present here the steps and phases of project
method and we give an example of how to use these elements in planning an
activity for celebrating the World Day for Water.

6. Practical application of
computer software in visual education
Erika Perge
Abstract: Education is an
active process in which instructors apply various devices to make the material
to be taught more suitable for students’ perception. As the capabilities of
available devices improve, so should the methods of teaching make the best use
of them. No tool can ever replace an instructor, but tools can enhance the
efficiency of education. Involving computers in the process of teaching is
feasible only when it can actually provide new educational methods that were
unavailable before, due to time or material limitations. In my article I’d like
to introduce two such new methods that, when used together with traditional
methods, can support visual education by increasing the number of possible
approaches to a topic being taught. One of these methods is about teaching
color theory, while the other is about shadows.

Brief History
Abstract: UNESCO
defines media education as the priority field of the cultural educational
development in the XXI century. The article presents the
development of media education since the beginning of it up to our days. The
sections of the article are the main periods for the development of the media

9. Multimedia and primary and secondary school curricula in
Liliana
Ciascai, Iuliana Marchis
Abstract. Multimedia is present
in our everyday life, thus its management is considered as a necessity by the
specialists. The relation of multimedia with education is very complex: we
speak about education with multimedia and multimedia education. In this paper
we propose to characterize partially the above mentioned relations, analyzing
the openness of primary and secondary school curricula for use of multimedia in
the learning process. This openness is
the first step toward multimedia education. In our investigation were analyzed
105 primary school programs and 157 secondary school programs for 39
disciplines. The obtained results
underline the lack of interest of policy makers to promote multimedia in
education. In the paper there are given some suggestions for directions of use
of media in school practice.

10. On
Competencies Characteristic of Geography in High School
Maria Eliza Dulamă, Oana-Ramona Ilovan
Abstract: The
purpose of our study was that of analysing, starting from literature, the definitions of the following concepts: capacity, skill,
and competency, as well as of analysing the competencies they phrased in school
curricula and those that teachers phrased. Moreover, we wanted to give
appropriate examples. The hypotheses of our study were the following: they had
not phrased correctly competencies in school curricula and teachers undergoing
a continuous training course or programme phrased correctly the competencies
characteristic of a certain field. This study had as a starting basis the
concept of competency as a sum of declarative knowledge, procedural knowledge,
and attitudes that were characteristic to an individual and that he or she
activated (transformed and integrated) in planning and solving certain tasks (Brien, 1997) in a certain field, in a certain case. Roegiers (1998) underlined that competencies had five
essential features: somebody’s calling up of a sum of resources (different
types of knowledge, experiences, capacities, schemes, automatisms, etc.);
finalised character; relation to a sum of situations; frequent subject matter
features; it could be assessed. To all these features we added another one,
that of the level of competency. In order to reach the above-mentioned purposes
and for verifying our hypotheses, we analysed the competencies in the high
school curricula and the competencies that 9 Geography teachers phrased, after
undergoing a continuous teacher training course on the “Development of Subject
Matter Skills and Competencies”. We concluded that taking into account the
features of the competency that Roegiers identified,
they did not phrase correctly those competencies and that hindered high school
students’ development and assessment. Out of the particular competencies in the
curriculum for Geography, in high school, we considered to be phrased correctly
or partially correctly only 5 for the 9th grade, 1 for the 10th
grade, 4 for the 11th grade, and 8 for the 12th grade. We
noticed that: teachers presented lists including different competencies; they included
competencies listed in our course, but without inserting all the possible ones
and added new competencies; they included both subject matter competencies and
non subject matter ones (or general ones); the group of teachers phrased 41
subject matter competencies and 48 general ones and phrased incorrectly 22
competencies, and these demonstrated that this course was an efficient one.
