Quality of  preservice teachers argumentation  in socioscientific issues context

This study aimed to explore preservice teachers’ (PTs) argumentation quality during socioscientific issues (SSI) based classroom discussions. The participants of the study were 20 PTs from the Department of Elementary Education at a large, research oriented public university in Turkey. Qualitative case study method was used in this study. The study covered four socioscientific issues (food additives, alternative energy sources, climate change, and the industrial revolution). Each issue was discussed in the classroom and each discussion was video recorded. Video recordings were transcribed verbatim and used as data source. Classroom discussions verbatim transcribes were analyzed by using a modified version of Toulmin’s argumentation pattern (TAP) model. The modified approach was found to be more conducive to informal argumentation patterns, in order to analyze preservice teachers’ use of claims, grounds, warrants, backings, and rebuttals that support their debate positions, as well as their ability to use evidence-based reasoning, form coherent lines of reasoning, and use of correct (appropriate) evidence. Results of the study revealed that preservice teachers’ use of evidence to support conflicting ideas tended to increase as their use of incorrect or insufficient use of evidence decreased through the present study.

Introduction: The co-authors provide an overview of the main types of wind turbines and power generators installed into wind energy devices, as well as advanced technological solutions. The co-authors have identified the principal strengths and weaknesses of existing wind power generators, if applied as alternative energy sources. The co-authors have proven the need to develop an algorithm for the selection of a wind generator-based autonomous power supply system in the course of designing windmill farms in Russia. Methods: The co-authors have analyzed several types of wind turbines and power generators. Results and discussions: The algorithm for the selection of a wind generator-based autonomous power supply system is presented as a first approximation. Conclusion: The emerging algorithm enables designers to develop an effective wind generator-based autonomous power supply system.

Concerns about climate change and fossil fuel shortages are encouraging interest in stumps, as alternative energy sources. Stumps are an almost unused resource in the context of bio fuels. Stump harvesting signifies an intensification of forest management compared with conventional stem-only or above-ground biomass-only harvesting. There are many benefits of stump harvesting. These include: the production of wood fuel, fossil fuel substitution, and improved soil preparation.Removing tree trunks in Hungary has been going on according to the principle of stump extraction, which means stumps are removed by grabbing technology. Experiments have been carried out to reduce the extraction force. In the Great Hungarian Lowland, where large areas require the operation implementation, stump extraction is done by special, hydraulic driven baggers equipped with a special bucket. During operation of the equipment, we carried out measurements of the extraction force and the time requirement. The experiments are designed to carry out the measurements with different soils and different tree species. According to our proposal the suitable force and torque required to remove stumps can be significantly reduced if before the lifting the soil — root connection is loosened. One of the possible ways to implement this task is the use of vibration. Since relatively great vibration power and wide domain of frequency are necessary, therefore we prepared the loosening machinery elements of alternating-current hydraulics system. Based on constructions variants we created a tractor-mounted experimental alternating-current hydraulic stump-loosening machine. It was designed with the ability to produce horizontal vibration in order to loosen stumps.

Subject. The article discusses limited sources of energy nowadays and an ongoing survey of new ones. I focus on fuel and energy complexes worldwide and in Russia. Objectives. The study is to analyze the future use of alternative energy sources in the fuel and energy complex nationwide and worldwide. I review the existing energy sources of the fuel and energy complex in the global and regional markets, specifically the alternative ones. Methods. The study relies upon methods of statistics, analysis and systems approach. Results. The article demonstrates that the fuel and energy complex strongly depends on the current situation in the energy resource market, which is difficult to forecast. If we continue relying on traditional energy resources, we get exposed to some risks affecting the sustainable development of the economy. Russia should diversify the power engineering sector by developing alternative energy sources. The article sets forth the economic rationale for alternative sources and key steps Russia shall make. Conclusions and Relevance. Considering the current situation in the energy balance, alternative energy is what any advanced society seeks for, being supported by manufacturers, governmental institutions, and researchers, though low profitability and high infrastructure costs impede its development. In Russia, these challenges are even more palpable. However, even now Russia is able to find alternative energy solutions. In addition to advantages of alternative energy, which is globally proclaimed, they will also help Russia diversify and update the economic system.
