Evaluation of school achievements of students with special educational needs – a preliminary study

In the first part of the article, the authors present new regulations in Kazakhstan that oblige teachers to monitor students’ academic achievements; they also draw attention to problems relating to the evaluation system for students with special educational needs in inclusive education. This gave grounds for undertaking research with the aim to analyze foreign experiences (in selected countries) and reflect in detail on the student evaluation system in Kazakhstan. In the next part of the article, the authors briefly outline Australian solutions and then provide a more detailed description of Polish and Russian solutions. A special focus is given to the analysis of the Kazakh system monitoring academic achievements in students with special educational needs, and both positive changes and the need to develop new systemic solutions are pointed out. The authors have found that I. Altynsarin National Academy of Education developed psychological and pedagogical approaches (student-centered, activity-based, and health-saving), pedagogical conditions, tasks, and functions of criterial evaluation of educational achievements, and requirements for a system of criterial evaluation of educational achievements of young students with special educational needs in an inclusive environment. At the same time, the questions concerning the procedure for evaluating individual achievements, the selection of methods, forms, means, and conditions of assessment as well as the consideration of personal indicators and the teacher’s professional and psychological readiness to participate in the assessment of students’ achievements have not been answered. That is why it is necessary to continue research on the process monitoring academic achievements in students with SEN that would result in creating a system to evaluate the performance of students with SEN, taking into consideration the Kazakh solutions and best practices as well as other countries’ experiences.

Evaluating Heat Resistance of Mold Shells in Investment Casting

The paper describes the theory of developing the heat-resistance criterion for disposable ceramic molds exposed to poured metal, creating a computational and experimental method for computing the heat resistance by rapidly heating the mold by an electric arc, as well as analysis of comparative data on quartz, dinas, and electric-corundum molds from the standpoint of the developed criterial-evaluation theory. In this case, the heat resistance is of one-time character, as this mold sustains only a single casting. Computational and experimental data indicate a low heat resistance of β-quartz, making them non-recommendable for annealing and metal pouring if there is not supporting filler. Molds based on electric-corundum or dinas fillers are free of such drawbacks, with the latter being considerably cheaper. The use of tridymited dinas powders is effective after grinding the spent dinas lining of electric furnaces.

Application of the criterial approach for the choice of forming technology for rod fasteners

The article presents the results of the application of the developed complex criterial approach for evaluating the production processes of fasteners such as bolts with hexagon head. An estimation of two technologies for manufacturing bolts was made, based on the criterial evaluation, the most rational production variance was selected.
