Creating of this article was motivated by the change of the new situation in connection with the Hungarian mathematics textbooks. Nowadays the teachers of Hungary could choose among the textbooks without restriction. The number of the textbooks is growing more and more. But our mathematics teachers have not any didactical support for the choice. Everybody knows that a suitable choice is not possible without an objective and measurable list of factors. We tried to give the Hungarian mathematics teachers such a list of factors, which is based on a theory concerning the choice of the English textbooks. This list of factors should make easier the choice of the textbooks on mathematics.

The aim of this article is to present some activities with multimedia, which can be used in intercultural education. The first part of the article presents those intercultural competencies, which have to be developed by the teacher. The second part presents some activities using different types of media for intercultural education purposes. All of the activities are tested in school/university, and the students' work is analyzed. Studying the products made by the students is very important for establishing if an activity is successful or not, if it contributes to the development of intercultural competencies. Thus the last part of the article contains an analysis and evaluation of all of the presented activities.

Multimedia presentation has its well-founded place in classwork and in the teaching process itself. Multimedia enables teachers to speak to their pupils and students through pictures and sounds. Computer presentation accompanies the teacher in the teaching process that thus becomes more comprehensive, well-considered and effective. In addition classwork supported by multimedia activities is more interesting and attractive for students. There is no doubt that the competence and skill in creating a multimedia computer presentation is one of the essential attributions of a teacher at any level of the educational system. We would like to outline the way of our realization of presentation creation teaching at Pedagogical Faculty of Ostrava University in Ostrava, Czech Republic. Our experience indicates that presentation creation must result from a detailed plan which is worked-out in advance. For the creation process itself, the student must be backgrounded with sufficient knowledge and skills in the presentation creation software (MS PowerPoint)--to create a template preset and shot succession, work with objects and animated effects, timing, etc. We give both onsite and online courses or a combination of both forms of lessons.

Due to progress in nanotechnology high-quality quantum wires can nowadays be fabricated. The behavior of particles in one dimension differs significantly from that in three-dimensional (3D) systems, yet the physics of such low-dimensional systems is generally not very well represented in standard undergraduate or graduate curricula. For instance, the Fermi liquid paradigm, working well for electrons in 3D systems, breaks down in 1D and has to be replaced by the Tomonaga-Luttinger liquid (TLL) description. However, most of the introductory papers on the TLL restrict themselves to a summary of results to be compared with experiments, while review papers are often fraught with technical details only accessible to the theorist. The present paper provides an elementary discussion of some phenomena distinguishing quantum wires and quasi-one-dimensional systems from their 3D counterparts targeting experimentalists and graduate students. It aims to convey the basic ideas of TLL theory and to relate it to alternative phases, such as charge and spin density waves. The important role of fluctuations in quasi-1D systems is pointed out and the connection is made to the problem of high-Tc superconductivity. The discussion is kept on a level, which should be accessible with a basic knowledge of quantum mechanics.

New media technology becomes more and more important for our daily life as well as for teaching physics. Within the scope of our N.E.T. research project we develop experiments using New Media Experimental Tools (N.E.T.) in physics education and study their influence on students learning abilities. We want to present the possibilities e.g. of smartphones as special new media devices serving as tools for conducting experiments in classroom physics and in daily life as well. In this paper, we give an overview about different methods for determining the gravitational acceleration as one of the most fundamental parameter in physics by using these easy-to-have and easy-to-use everyday tools. The theoretically backgrounds of the experiments range from the simple use of the law of gravitation to the coefficient of restitution and refer to different physical concepts (mechanics and acoustics). So each of these experiments requires different pre-conditions and it&apos;s possible to conduct these experiments and determine this most fundamental parameter in classroom physics by completely different types of learners (high-school as well as college level).

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.

The purpose of this article is to give the intelligible procedure for undergraduate students to grasp proof of the fact that the magnetic field outside the hollow superconducting sphere (superconducting shell) coincides with the field of a point magnetic dipole both when an uniform external magnetic field is applied as when a ferromagnetic sphere is located at the shell&apos;s geometric center. The proof is based on the London&apos;s equation transformation to an integral equation for the vector potential of system. The integral equation may be solved completely in case of the solid sphere.

Education is an active process in which instructors apply various devices to make the material to be taught more suitable for students&apos; 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&apos;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.

Science teachers&apos; competencies are analyzed in this paper. The importance of teachers&apos; competencies is underlined and also the importance of competencies in so called &quot;good practices&quot; obtaining, is studied. The definition of science teachers competencies and their taxonomy are very important in understanding the educational reform in European context. The recent literature and many reforms in the field of science teacher education suggest that teacher preparation has a &quot;threefold structure&quot; with the anchoring pillars being Subject Matter Knowledge (SMK), Pedagogical Knowledge (PK) and Pedagogical Content Knowledge (PCK). Science education programs should pay more attention into the learning of science in social and technological context. The reform in the educational field has to pay a special attention on science teachers&apos; competencies.

This study describes an approach for blind students thought health physics about how they could set a hypothesis and test it. The participant of the study used some health materials designed for high school blind student and tested her hypothesis with the data she gathered with those materials. It was asked that she should hypothesize which could be tested with the given material and reflected her own interest. At the last step of the case study she asked an expert to construct the data meaningful and tested her hypothesis. Positive expressions of blind student after her hypothesis testing, indicates that blind students possible use and develop their science process skills through health physics.

In this study, a Thermodynamic Concept Test (TCT) was designed to assess student's conceptual understanding heat and thermodynamics at undergraduate level. The different statistical tests such as item difficulty index, item discrimination index, point biserial coefficient were used for assessing TCT. For each item of the test these indices were calculated. For the entire test, test reliability and Ferguson's delta was calculated. Analysis of data shows that the students have serious difficulties in understanding of heat and thermodynamics in particular and physics in general when taught through traditional teaching method.

Many physics professors have difficulties to know and assess in real time the learning of the students in their courses. Nevertheless, today, with Internet and the new technology devices that the students use every day, like smartphones, such tasks can be carried out relatively easy. The professor pose a few questions in &quot;Socrative,&quot; the students answer them by means of the Smartphone. In this way, the professor knows what students learned and can promote the cooperative learning joining students who think differently, with the purpose to give them chance to discuss their answers and argumentations and, eventually, to improve both answers and arguments. In this article, we present the results of an initial feasibility study of using &quot;Socrative&quot; and smartphones carried out with prospective teachers. The effects on the students were: they help them to understand concepts; they facilitate the argumentation and the exchange of opinions. In addition, the use of this technology is, generally, easy for students and turns out to be interesting in the classroom. In conclusion, by using efficiently &quot;Socrative&quot; and students&apos; smartphones, professors might achieve jointly three different goals: real-time assessment of the students&apos; learning, motivation of the students and increased opportunities for active learning.

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.

There are a variety of teaching tools available for use in introductory modern physics classrooms. Determining which teaching tool students support can help the teacher structure classroom instruction to include more effective teaching tools. Student participants were surveyed at the end of four separate semesters after using different teaching tools throughout the semester. They were asked to rate which teaching tools they found to be most effective in aiding their understanding of the course material and provide comment where necessary. Students on a &quot;least effective&quot; to &quot;most effective&quot; scale rated each teaching tool. This scale was transferred into a number scale with 1 being &quot;least effective&quot; and 5 being &quot;most effective.&quot; Through use of the quantitative and qualitative analysis, it was determined that students strongly prefer the use of in-class worksheets. The normalized data shows that 68% of students strongly favored the worksheets over textbooks (29%) and homework (32%). Students gave positive comments that the in-class worksheets allowed for teacher-student interaction and guided learning.
Teaching the Falling Ball Problem with Dimensional Analysis

Dimensional analysis is often a subject reserved for students of fluid mechanics. However, the principles of scaling and dimensional analysis are applicable to various physical problems, many of which can be introduced early on in a university physics curriculum. Here, we revisit one of the best-known examples from a first course in classic mechanics, namely the falling ball problem: a ball is thrown with an initial velocity and height while experiencing gravity and viscous drag. We treat two representative cases of drag forces, one linear and one quadratic in velocity. We demonstrate that the ball&apos;s motion is governed by two dimensionless parameters: (i) a Froude number (&quot;Fr&quot;) comparing the ball&apos;s initial kinetic to potential energy and (ii) a drag coefficient (C[subscript D]) comparing the initial drag force to the ball&apos;s own weight. By investigating extreme, yet simple hypothetical cases for &quot;Fr&quot; and C[subscript D], we demonstrate how students can grasp the role of the parameters relating the ball&apos;s initial conditions in governing several physical behaviors displayed by the system. Advocating early on exposure to dimensional analysis is undoubtedly beneficial in building physical intuition, but also it illustrates how physical systems characterized by many variables may be assimilated by reducing their inherent complexity.

Nature is a complex causal network exhibiting diverse forms and species. These forms or rather systems are physically open, structurally complex and naturally adaptive. They interact with the surrounding media by operating a positive-feedback loop through which, they adapt, organize and self-organize themselves in response to the ever-changing environment. Interaction is a two-way process, by which a system extracts as well as dissipates information into the surrounding. Information transcends through the levels of hierarchy triggering a series of phenomena in nature. Every natural phenomenon thus forms a part of an infinite (&quot;natural&quot;) causal chain.
