Mayer R.V.  The “Physical Field” concept and peculiarities of its application in formation of the scientific worldview in student’s mindset


pp. 7581

DOI: 10.25136/24098736.2019.2.27542
Abstract: The object of this research is the process of studying the gravitational, electromagnetic and other physical fields. The goal is to analyze the formation of the “physical field” concept, which is the core of conceptual field incorporating the “gravitational”, “electric”, “magnetic”, “electromagnetic”, “nuclear forces” and others, from the perspective of didactics and cognitive linguistics; determine the imageryperceptual component of the concept, its structure and key cognitive qualities; examine the specificities of their representation of the courses of “Physics”, “Concepts of Modern Natural History”, and “Natural Science Worldview”. The following methods were used in the course of this research: 1) analysis of the definitions of concept, determination of the key cognitive qualities; 2) studying the sensual and visual image formed in a student’s mindset; 3) semantic and cognitive analysis of academic texts; 4) building of the semantic model. The result of quantitative analysis of the various textbooks established that the conceptualization of “physical field” first and foremost suggests the examination of the following cognitive qualities: “physical field – form of matter”, “gravitational field”, “field of gravity”, “electric and electrostatic filed”, “magnetic field”, “electromagnetic field, and “field worldview (concept, theory)”.
Mayer R.V.  On evaluation of difficulty of educational text in natural scientific disciplines


pp. 5664

DOI: 10.7256/24098736.2016.4.19501
Abstract: This article is dedicated to the question of evaluation of didactical difficulty of the educational text. The author introduces the notion of didactical difficulty as the characteristic proportional to time that is required for digestion of information presented in the text. The universal criteria of evaluation of difficulty of the notions on various natural scientific disciplines are being proposed. It is substantiated that didactical difficulty of the studied in school questions is defined by the diversity and abstractness of the qualitative and mathematical models. The author analyzes the modern textbooks on environmental studies, geography, biology, physics, and chemistry, as well as performs their pairwise comparison with each other. The article examines the two methods of determination of the didactical difficulty of educational texts: 1) through calculation of the number of scientific terms and consideration of their difficulty using the computer; 2) by means of pairwise comparison of various texts with each other. The scientific novelty consists in proposition of the criteria of assessment of the didactical difficulty of scientific notions, as well as analysis of the results of expert evaluation of the textbooks from the perspective of difficulty of the qualitative and quantitative models.
Mayer R.V.  Rotation of theoretical and practical activities as an effective method of education: Results of imitation modelling


pp. 145155

DOI: 10.7256/24098736.2015.4.16041
Abstract: The subject of this research is a computer model of a student based on the following hypotheses: 1) in the course of studying the student acquires new knowledge, and the unsubstantiated knowledge transforms into substantiated; 2) the efforts applied by a student depend on the disparity between the requirement of the teacher and the knowledge of the student; 3) with increase in speed of presentation of new material, the coefficient of the transfer rate in the “teacherstudent” communication channel decreases. The article examines the methodology that consists in splitting the theoretical and practical material into several parts and their alternation. The scientific novelty lies in the following: 1) the author suggests the new computer model of a student that takes into account the transformation of the surface knowledge into deep knowledge, and the nonlinear dependencies of a student from the teacher, and the coefficient of the transfer rate of communication channel from the speed of presentation of new material; 2) by the means of imitation modelling it is demonstrated that the alternate studying of theory and practice leads to a greater result.

Mayer R.V.  Computer TwoComponent Probability Model for Studying Academic Disciplines


pp. 4252

DOI: 10.7256/24098736.2015.1.13701
Abstract: The article is devoted to the solution of the main task of the mathematical learning theory which is to define the level of knowledge of a student studying a discipline. The researcher states that all the acquired academic knowledge can be conditionally divided into the two categories: 1) ephemeral knowledge that is easily forgotten, and 2) timeproof knowledge (skills) developed through multiple repetitions of the academic material that is slowly forgotten. The given simulation model also takes into account the dependence of the ratio of knowledge acquisition and time a student spends on studying the material on the overall level of student's actual knowledge. To achieve the objectives of the research, the researcher has used the methods of the analysis and synthesis of complex systems, mathematical and computer simulation. The scientific novelty of the research is caused by the fact that the researcher proves that it is possible to create a twocomponent probability model for studying an academic discipline and this model may include: 1) probability of a student studying a new issue or repeating the material; 2) increasing share of timeproof knowledge as a result of a growing number of repetitions; 3) reduction of time spent on studying a particular material while repetitions of the material grow; 4) growing ratio of knowledge acquisition while the overall quantity of knowledge and/or knowledge of this particular material multiply. The given model allows to monitor the dynamics of student's growth of overall knowledge and his knowledge of a particular discipline.

Mayer R.V.  Computational experiments in studying of wave processes in linear and nonlinear media


pp. 5765

DOI: 10.7256/23064196.2014.4.12683
Abstract: The course of physics in colleges and universities includes various wave processes: reflection and transmission of the pulse through the interface between two media, interference, wave propagation in a dispersive medium, the formation and interaction of solutions. Here it is important to combine theoretical and practical approaches to studying of these phenomena with computer models, allowing creating visual image of the phenomenon and analyzing its behavior in different conditions. The subjects of the study are the simple computer models and computational experiments helping to show the wave processes in the onedimensional linear and nonlinear media. The experiments require mathematical and computer modeling, building a mathematical model, creating software simulating the studied phenomenon based on the numerical solution of the corresponding system of equations. The novelty of the work is in the fact that the author presents three simple computer programs written in Pascal, simulating pulse propagation in onedimensional medium, its reflection from the boundary between two media, and its passage of the second medium, the wave propagation in a dispersive medium, the formation of different solutions and their interactions. The analysis of the results of computer modeling allows to state that the use of such computational experiments based on the simulation of a onedimensional medium by a system of coupled springing or simple pendulums or solving the sineGordon equation really allows to study the wave processes at a higher level and to form interest in physics and information technologies.
