Formation of creative activity of secondary school using musical digital technologies

In the education process of the elder students (of 8 – 12 classes) of the secondary school the pedagogical activity is to be oriehted to the needs of the needs of the student, upbringing of creative abilities improvising on the music lessons, capability to adopt the modern digital technologies in various self-expression areas. Namely the lack of digital technologies influences the little interest of students for music lesson: it conditions the passivity and causes the problems of discipline. The object of research is formation of creative activity of student of secondary school using digital technologies on music lessons. Objective is to reveal the importance of introduction of musical improvisations and particularities of creation by students using digital technologies, also forming the positive and active attitude of students towards the taught subject of music. Hypothesis is raised that if the synthesizer, computer and other digital technologies are used on music lesson in order to develop the creative activity of the student then the attitude of students toward subject of music will become more motivated, the musical subject will become more motivated, the musical subject will assume more attractiveness. The methods of theoretical, empirical and mathematical analysis are used in this work. The descriptive research was performed in the Dzukijos secondary school of Alytus. 226 students (of 8 – 12 classes) and teachers of music of secondary schools from Alytus city and district participated in the named research. The conclusions are resumed that with the help of digital technologies the student reaches the performance freedom, ensures the success of implementation of musical dreams, comments his/her project/comcept, makes the experiments with sound, searches for its characteristics, uses new music generation measures, gets the experience, involves himself/herself systemically to the musical action, thinks creatively, adopts his/her creation in practice; then there appears the understanding of musical “time signature”, sensation of swing,feeling of ensemble, the attitude changes towards creation (creator), the interests in music exposes.Švietimo akademijaVytauto Didžiojo universiteta

Adapting elements of improvisation in piano lessons - the motivation factor

Magistro darbe nagrinėjamos naujos pianistų, pritaikant muzikines improvizacijas, ugdymo galimybės. Muzikos mokyklų fortepijono klasės moksleivių ugdymo procese pedagoginė veikla turėtų būti orientuojama į vaiko poreikius, kūrybinių gebėjimų ugdymą improvizuojant fortepijono pamokose, sugebėjimą pritaikyti improvizacijas įvairiose saviraiškos srityse. Būtent improvizacijų stygius įtakoja mažą moksleivių suinteresuotumą fortepijono pamoka, sąlygoja pasyvumą, nenorą groti. Tyrimo objektu pasirinkta improvizacijų diegimas muzikos pamokose. Tikslas – atskleisti muzikinių improvizacijų diegimo reikšmingumą, formuojant teigiamą, aktyvų moksleivių požiūrį į dėstomą muzikos dalyką. Iškelta hipotezė - jei fortepijono pamokoje moksleivio kūrybinei veiklai plėtoti bus naudojamos improvizacijos, moksleivių požiūris į fortepijono dalyką taps labiau motyvuotas, muzikos dalykas taps patrauklesnis.The Master's thesis deals with the new educational opportunities of the pianists by adapting musical improvisation. In the educational process of the piano students of the music schools, pedagogical activities should be oriented to the needs of the child, the development of creative skills through improvisation during the piano lessons, the ability to adapt improvisations in the various fields of self-expression. It is the lack of improvisation that influences the low interest of the students in the piano lesson, causes passiveness, reluctance to play. The subject of study is the integration of improvisations in the music lessons. The objective is to reveal the significance of implementation of the musical improvisations, by formation of a positive, active attitude of the students to the taught musical subject. The hypothesis: if during the piano lesson the student's creative activities are developed through the use of improvisations, the students' approach to the piano subject will become more motivated, the musical subject will become more attractive.Muzikos akademijaVytauto Didžiojo universiteta

Nanostruktūrizuotų La-Sr(Ca)-Mn-O sluoksnių magnetovarža ir elektrinės varžos relaksacija

The goal of this thesis was to investigate, how chemical composition and morphology of La-Sr(Ca)-Mn-O nanostructured films influences the resistivity and magnetoresistance values in wide range of temperatures and magnetic fields, and to clear up origin of memory effects occurring after the magnetic field pulse affected the films is switched off. It was demonstrated that the magnetoresistance of nanostructured manganite films can be analyzed using modified Mott’s hopping model taking into account contributions of both crystallites and grain boundaries. It was found that resistance relaxation process in these films after magnetic field is switched off has two different components: ‘fast’ (> 100 µs), and ‘slow’ (≥ 1 ms). The characteristic time constants and relative parts of the remnant resistivity of these processes were systematically analyzed in a wide range of temperatures and magnetic fields using Kolmogorov-Avrami-Fatuzo and Kohlrausch–Williams–Watts models. The obtained results enabled to suggest the development of fast high pulsed magnetic field sensors operating at two ranges of temperatures: close to room and cryogenic. It was also shown that the treatment of nanostructured manganite films by annealing them in an argon atmosphere at 100-200 C temperatures accelerates their ageing processes and stabilizes their resistance and magnetoresistance

Computer controlled thermostat for the resistivity measurements of the La1-xSrxMnO3 thin films

The temperature stabilization system for the magnetoresistance measurements of the La1-xSrxMnO3 manganites is described in this paper. The thermostat cell with the Peltier heating/cooling element was manufactured specially to be placed between the poles of the electromagnet. The heat sink attached to the rear side of the Peltier element is cooled by the flowing tap water. Platinum film temperature probe was used for the temperature feedback signal. Universal multimeter “Tektronix DMM 4050” was used as a temperature meter and a regulated laboratory power supply “TTI QL 564P” was used to supply the current through the Peltier element. Both instruments were controlled by the computer software via the USB and GPIB interfaces. The software implementing a PID algorithm was written in the LabView graphical programming interface. The results show that the temperature of the sample can be changed in 2-3 minutes depending on the temperature step and is kept constant with precision of ±0.02 °C
