We studied the thermal stability and many-sided properties of Y 0 .5 Sr 0 .5 Cr 0 .5 Mn 0 .5 O 3 chromite-manganite that was made using the sol-gel method.We focused on the syngony type, unit cell parameters, and x-ray analysis.To con􀅫irm the results of the chromite-manganite indexing, the inverse values of the squares of interplane distances (104/d2) and the consistency of the x-ray and pycnometric densities were found to be very close to each other.It was found that the synthesised chromite-manganite crystallises in orthorhombic syngony and has a perovskite-like structure.Scanning Electron Microscopy (SEM) shows that chromite-manganite is uniformly distributed, and the crystallites are sized between 6 and 20 microns.The analysis of the relationship between heat capacity and temperature using the Thermo Gravimetry Analysis (TGA) technique demonstrates the stability of the internal structure and the presence of polymorphic transformations in the sample under study.

The study explored the association between student-centred teachings and innovative skill development in art design students.Furthermore, the role of students' engagement and students' performance was assessed using a student-centred approach and students' innovative skills.Furthermore, the importance of the student-centred approach among art and design students in the sixth, seventh, and eighth semesters was assessed.In total, 365 students were included in the study: 115 from the sixth semester, 120 from the seventh semester, and 130 from the eighth semester from Abai Kazakh National Pedagogical University, Institute of Arts, Culture, and Sports.The data collection was performed at three different periods using a time-lag approach.Furthermore, it was found that students' creative skills are positively associated with student-centred teaching methodologies.Whereas students' level of engagement is directly linked with the student-centred approach, and students' engagement is directly associated with students' innovative skills.Similarly, students' performance is positively associated with the student-centred approach and innovative skills.The study highlighted the importance of student-centred teaching methodologies in developing students' performance and engagement.Lastly, students' innovative skills in art and design can be developed using a research model by focusing on the teaching methodologies, students' engagement, and the need for innovative skills for future design specialists.
