The problem and the aim of the study. The formation of critical thinking is one of the most important tasks that teachers face in the vocational education system. The complexity, versatility of the studied objects, phenomena and processes of reality make it necessary for the mentors of the digital school to look for universal methods of cognition. The authors propose to use the modeling method in 3D graphics environments to form critical thinking as an important skill that meets the challenges of globalization and transformation. Research methods. The main method is modeling, as a general scientific method for studying the phenomena of reality using the analogy between the model and the original. The research was carried out on the basis of Vyatka State University for students of the training programme 44.04.01 Pedagogical education, profile Informatization of Education (master degree level). A software tool for organizing modeling as a method of teaching and scientific cognition is SketchUp. The Pearson’s χ2 (chi-square) criterion was used as a method for statistical processing of the experimental data. Results. The students of the experimental group used modeling in the environment of three-dimensional graphics at the following stages: acquiring theoretical information about the original object, creating a substitute model, developing a system of research problems, reflection, checking and adjusting the results in the conditions of the original object, the statement of a qualitatively new knowledge. The assessment of the levels of formation of critical thinking was carried out and statistically significant differences in the qualitative changes that occurred in the pedagogical system were revealed, χ2emp.2 > χ2crit0.05 (6.42 > 5.99). In conclusion, the conditions under which three-dimensional modeling contributes to the development of basic properties that ensure the formation of critical thinking are generalized: application together with other methods of scientific knowledge; modeling not only in a software environment for creating a 3D project, but also developing an Instruction as a model for its practical application; obtaining qualitatively new knowledge, etc.

The problem and the aim of the study. Preparing a graduate capable of individual creative thinking, ready to work in a team, and to manage changes, projects, teams is one of the most important tasks that digital school teachers face. The effectiveness of its solution depends on the experience of collaboration, tools of virtual interaction, the formation of group thinking. The authors propose to use collective virtual walls to form group creative thinking as an important skill corresponding to the conditions of uncertainty of the future. Research methods. To activate cognition, create favorable conditions for creativity and discoveries when working together, methods of group interactive learning are used (demonstration in a remote mode of interaction, online discussion, project presentations, work on a collective virtual wall). The study was carried out on the basis of gymnasium No. 2 in Kirovo-Chepetsk. As a software tool to support online collaboration and co-creative discovery, the Trello service (https://trello.com/) was used. As a method for statistical processing of the experimental data, the Pearson’s χ2 (chi-square) criterion was used. Results. In the experimental group, students used collective virtual walls to obtain theoretical information, complete practical tasks in an interactive online environment, creative search and experience of collective discovery, group reflection and presentation of team projects. The assessment of the levels of formation of group creative thinking was carried out and statistically significant differences in the qualitative changes that occurred in the pedagogical system were revealed, χ2 emp. 2 > χ2crit0.05 (6.89 > 5.99). In conclusion, the authors generalized the conditions under which joint activity over a collective virtual wall contributes to the formation of group creative thinking. The conditions are: awareness of the meaning and motives of joint activity; the need for self-expression and active participation in the discussion; work according to a general plan; analysis of the progress of an individual task and the entire collective project; control and self-control; direct interpersonal communication, virtual communication, etc.

The objective of post-evaluation Treasurer Training in 2015 is to analyze the influence of Treasurer Training programme design to the competency of treasurers which contribute to bettermen of their duties and tasks as treasurer, furthermore, to analyze the subject of Treasurer Training which need to refined. This post-evaluation research respondents are alumni, alumni's superiors, and alumni's peers of Treasurer Training in the first semester of 2015. This research utilizes interview and disseminates questionaries to alumni, superiors, and peers. Data processing is carried out using descriptive statistics with SPSS and Microsoft Excel. The research output including three competences show that score of knowledge competence is 4.53 (very good), score of skills is 4.54 (very good) and attitude is 4.52 (very good). The result of Chi-Square test shows that there is no difference in competence evaluation by alumni, superiors, and peers so it is considered objective.

Three Dimensional Modeling

The square checkerboard buckling deformation appearing in indium antimonide infrared focal-plane arrays (InSb IRFPAs) subjected to the thermal shock tests, results in the fracturing of the InSb chip, which restricts its final yield. In light of the proposed three-dimensional modeling, we proposed the method of thinning a silicon readout integrated circuit (ROIC) to level the uneven top surface of InSb IRFPAs. Simulation results show that when the silicon ROIC is thinned from 300 μm to 20 μm, the maximal displacement in the InSb IRFPAs linearly decreases from 7.115 μm to 0.670 μm in the upward direction, and also decreases linearly from 14.013 μm to 1.612 μm in the downward direction. Once the thickness of the silicon ROIC is less than 50 μm, the square checkerboard buckling deformation distribution presenting in the thicker InSb IRFPAs disappears, and the top surface of the InSb IRFPAs becomes flat. All these findings imply that the thickness of the silicon ROIC determines the degree of deformation in the InSb IRFPAs under a thermal shock test, that the method of thinning a silicon ROIC is suitable for decreasing the fracture probability of the InSb chip, and that this approach improves the reliability of InSb IRFPAs.

AbstractBiofilms are microbial communities that represent a highly abundant form of microbial life on Earth. Inside biofilms, phenotypic and genotypic variations occur in three-dimensional space and time; microscopy and quantitative image analysis are therefore crucial for elucidating their functions. Here, we present BiofilmQ—a comprehensive image cytometry software tool for the automated and high-throughput quantification, analysis and visualization of numerous biofilm-internal and whole-biofilm properties in three-dimensional space and time.

The presented article deals with the issue of solving bottlenecks in the logistics flow of a manufacturing company. The Tx Plant Simulation software tool is used to detect bottlenecks and deficiencies in the company’s production, logistics and transportation systems. Together with the use of simulation methods and lean manufacturing tools, losses in business processes are eliminated and consequently flow throughput is improved. In the TX Plant Simulation software environment, using Bottleneck analyzer, bottlenecks were defined on the created simulation model and a method of optimizing logistics flows was designed and tested by introducing the Kanban pull system. This resulted in an improvement and throughput of the entire logistics flow, a reduction in inter-operational stocks and an increase in the efficiency of the production system as a whole.
