The results of this study concluded that there is significant influence of certified teachers and principal leadership either partially or simultaneously toword teachers’ performance of primary school in Palembang.

A new cyanobacterial strain was isolated and purified from salt Lake Balkhash, Kazakhstan. According to its morphological and ultrastructural characteristics, 16S rRNA sequence and the fatty acid profile, the strain has been classified as Cyanobacterium spp. and assigned as Cyanobacterium sp. IPPAS B-1200. The strain is characterized by a non-temperature inducible ∆9-desaturation system, and by high relative amounts of myristic (14:0-30%) and myristoleic (14:1∆9-10%) acids. The total amount of C 14 fatty acids reaches 40%, which is unusually high for cyanobacteria, and it has never been reported before. The remaining fatty acids are represented mainly by palmitic (16:0) and palmitoleic (16:1∆9) acids (the sum reaches nearly 60%). Such a fatty acid composition, together with a relatively high speed of growth, makes this newly isolated strain a prospective candidate for biodiesel production.

Among the most significant trends in the development of vocational education, introduction and use of educational technologies can be distinguished. Since the main goal of higher schools is to prepare a competent competitive specialist, they search for the most suitable methods that contribute to rapid achievement of results. The use of technologies by educational institutions is explained by their advantage over other methods of developing professional competence. Due to implementation of a certain algorithm of actions, they allow you to achieve guaranteed results in a timely manner. The purpose of the article is to form future teachers ' the level of competency development, reflecting students’ willingness to adapt, adjust and use educational technologies in professional teaching activities. To do this, we checked the level of motivation of future teachers, the level of knowledge of the theoretical foundations of educational technologies, their design and implementation in professional and pedagogical activities, and the level of formation of the ability to reflect. The development of competencies reflecting the student’s readiness to adapt, adjust and use educational technologies in professional pedagogical activity was carried out in a certain logical sequence, so that the student possessed versatile knowledge about educational technologies, was capable of their systematic creative application and his reflective activity was associated with self-actualization and striving for the implementation of constructive professional activities. The development process was carried out in the course of students solving research and design problems. Research activity was carried out by students in the study of the course “Pedagogical technologies”, fundamental for future teachers of vocational training. The implementation of the projects was carried out during the development of the course "Project Activities of a Professional Education Teacher".
