The impact of folk games on primary school students

Kazakhstan's efforts to expand its physical culture have brought tremendous benefits. However, there are still unresolved issues in the teaching of physical education in our country's schools. Despite many ethnic and cultural traditions, combining learning opportunities in the classroom is ineffective. Domestic experience in sports is underutilized due to a lack of educational literature and scientific evidence that supports the use of traditional outdoor sports. The purpose of this study is to improve the motor abilities of young children by using carefully selected traditional outdoor sports. A study on the use of folk games in working with children in primary schools found that teachers' knowledge of the possibilities of folk games is inadequate. Finally, the findings suggest that incorporating traditional games into the physical education curriculum for students in lower grades can serve as a model for healthy lifestyles. Various types of games and exercises help to improve physiological systems, physical development and physical fitness in children and foster positive moral and volitional qualities

Method of Measuring Permittivity of Composite Materials with Hexagonal Ferrite Inclusions

A new simple method for measuring complex permittivity of substantially lossy composite materials is presented. In this method, a sample of the material under study should completely fill in the cross-section of the single-mode transmission line (waveguide), and the length of the sample must be an integer of a half-wavelength in the waveguide filled with this material. The oscillator frequency is swept linearly, the minima of the reflection coefficient are measured, and then analytical formulas are used to calculate real and imaginary parts of permittivity. The method was tested on magneto- dielectric samples containing hexagonal ferrite powders, as well on such dielectric materials, as PMMA, schungite composites, and alabaster. This method can be a useful technique for measuring dielectric properties of absorbing materials designed, for example, for electromagnetic shielding purposes

The visual arts' role in the development of students' noosphere worldview

Noospheric education is considered the basis for the formation of an environmental culture in people and society aimed at solving a complex of problems related to ensuring the sustainable development of society. Identifying promising areas for noospheric education development and demonstrating the importance of students developing a noospheric vision of the world through the visual arts depend on whether the necessary conditions for achieving the desired results have been established. This study aims to examine the impact of software on the effective formation of students' noospheric vision of the world using the visual arts. A quantitative and qualitative research design was used in this study. The study involved 240 fourth-grade students at secondary school no. 12 in the city of Almaty (Kazakhstan). The findings revealed issues with the formation of students' noospheric worldviews which demonstrates that students have an unstable perception of the intellectual sphere   and develop an enthusiasm for the bright, spectacular objects and phenomena of their surroundings rather than their content. Experts can use the research findings to model environmental education in secondary schools, in the practical work of visual arts instructors, in the creation of curriculum and instructional aids for the visual arts and in the transmission of information on noospheric concepts

The impact of formative assessment techniques on students' self-assessment skills

The introduction of formative assessment to improve students' self-assessment skills was one of the main innovations in Kazakhstan. However, there are issues with the implementation of formative assessment and its introduction. This study aims to examine the impact of the author's formative assessment techniques on students' self-evaluations. One of the methods was experimental work carried out in 2021-2022 at Almaty Secondary School No. 198. This study was carried out using 55 fourth grade students   consisting of 27 students in grade four "A" (16 girls and 11 boys) as the experimental group (EG) and 28 students in grade four "B" (18 girls and 10 boys) as the control group (CG). The results identified problems with the introduction and implementation of formative assessments. This highlighted the importance of developing formative assessment strategies to improve students' self-evaluations.   Our findings confirm that the identified and methodically substantiated procedures for improving self-assessment in students in primary school may be employed in classes with younger students and in teacher training groups

Students' perspectives of a hybrid learning system in Kazakhstani higher education: A case study

Hybrid learning is a relatively new approach in Kazakhstan's educational system. The transition to a new format necessitates a significant amount of effort and restructuring at the universities. The problems of researching   the advantages and disadvantages of implementing this kind of instruction in the classroom are very relevant. The study's goal was to investigate students' attitudes towards implementing a hybrid learning environment. A qualitative method of data analysis was applied in the study.  1,186 students participated in hybrid learning at various universities in Kazakhstan. According to the findings, students value the flexibility and convenience of attending classes remotely through a two-way video conference. However, the findings also indicate that this new learning environment faces several pedagogical and technological challenges. These findings emphasize the importance of assisting students in understanding hybrid learning resources and goals   thereby creating opportunities for success in hybrid learning. Policymakers in education can use it as a guide to develop policies related to crisis management or inclusive education   as well as curriculum documents and resources for hybrid learning

The impact of integrated technology on students' logical thought in mathematics: A case study of Kazakhstan

Air pollution in the workplace: making shish kebab is an overlooked occupational hazard

Meat grilled with wood charcoal is the most popular meal in Central Asia, but little is known about the grillers’ occupational exposure to fine particulate matter (PM) in fumes. The aim of this study was to provide a quantitative analysis of occupational exposure to fine PM in grillers in the workplace. We assessed exposure to PM2.5 from barbecue fumes using SidePak AM520 in six popular cafes in Almaty, Kazakhstan. Grillers wore devices for 8 h of work shift for 7 days in each place. Within- and between-place variances of PM2.5 mass concentrations were calculated using analysis of variance, and we also calculated the fold range of the 95% variance within (wR0.95) and between places (bR0.95), as well as exceedance (γ) and the probability of overexposure (θ). Very high occupational exposure to barbecue fumes in grillers is overlooked and likely causes elevated health risks
