The article gives a geobotanical description and a floristic analysis of communities with the participation of the rare and relict species Alnus glutinosa in condition of Aktobe region. The aim of the study is to provide a geobotanical assessment of the current status of a rare, relict species of the Alnus glutinosa population, which was included in the Red Data Book of Kazakhstan. At present, the flora of the Aktobe region is not sufficiently studied. Conservation of the biodiversity of the Aktobe region flora is one of the most topical issues. In Aktobe region, due to the lack of grazing, felling of trees, using as fuel and the emergence of uncontrolled tourism and at the same time due to the lack of natural renewal of the area, these consequences lead to a quantitative reduction in the species. In this regard, it is necessary to study the species and organize protection and conservation measures. The results of the study showed that the plant Alnus glutinosa is rarely found in the flora of Kazakhstan and also the distribution areas are reduced. Of the three investigated points, plants from 24 families were identified. Plant communities of Alnus glutinosa are being studied for the first time in the Aktobe region. For the first time in the conditions of the Aktobe region, the habitat of black alder was discovered. The floral composition of plant communities of Alnus glutinosa grown in various ecological environments was revealed, the ratio of life forms and phytocenotic features were studied for the first time. In addition, alder felt mite and ground bug, damaging black alder, were identified from 3 studied populations. It has been established that the main reason for the spread of this pest is a very strong moistening of the ground on which sticky Alder grows. Results sequencing showed that the DNA sample under study belongs to the fungus Alternaria alternata.

Cyclachaena xanthiifolia (Nuttall) Fresenius, an invasive species belonging to the "transformer" species capable of radically transforming natural plant communities and influencing the taxonomic and phylogenetic uniqueness of regional floras, was found for the first time on the territory of the Aktobe region. The plant was found on the territory of Aktobe , three cenopopulations with C. xanthiifolia have been described. All the studied cenopopulations are small-species containing 7-9 species and consist of ruderal species. In all three cenopopulations, C. xanthiifolia together with Chenopodium album are the dominant plant communities., the partial projective coverage is 20%., the density in populations is from 12.0±3.1 to 17.0±2.6 pcs/m2, the height varies from 80.0±9.3 to 138±14.0 cm. The activity of C. xanthiifolia is very high and is second only to C. album.

В статье рассматривается влияние самооценки на успехи учащихся среднего звена в изучении биологии как учебного предмета. Авторы подчёркивают, что самооценка является важным психологическим компонентом, напрямую связанным с учебной мотивацией, эмоциональным состоянием и готовностью учащихся к преодолению трудностей. Анализируются факторы, влияющие на формирование самооценки: педагогические условия, социальная среда и индивидуально-психологические особенности личности. Раскрывается роль учителя в создании благоприятного образовательного климата, способствующего развитию уверенности и самоуважения у учеников. Статья содержит обзор практических методов повышения самооценки, таких как рефлексия, ведение дневника достижений, анализ ошибок, тренинги на постановку целей и развитие позитивного мышления. Подчеркивается значение практической деятельности, особенно при изучении биологии, требующей аналитических навыков, самостоятельности и уверенности. В рамках исследования было проведено анкетирование учащихся 7 классов, в котором анализировался их уровень самооценки, восприятие учебных достижений, отношение к ошибкам и стремление к взаимодействию с учителем и сверстниками. Опрос, в котором приняли участие 61 ученик, позволил получить данные о восприятии учащимися собственных учебных возможностей. Результаты показали, что учащиеся с высокой самооценкой демонстрируют большую учебную активность, лучше воспринимают критику и успешнее справляются с биологическими задачами. Авторы делают вывод о необходимости целенаправленной педагогической поддержки самооценки, особенно в подростковом возрасте, когда активно формируется личность. Развитие позитивной, адекватной самооценки рассматривается как условие успешного обучения и гармоничного личностного роста учащихся..

Амилазы представляют собой группу ферментов, которые широко распространены в микробном, растительном и животном мире. Они разлагают крахмал и родственные полимеры с образованием олигосахаридов. По субстратной специфичности амилазы классифицируются на α- и β- амилазу, которые катализируют гидролиз гликозидных связей в амилозе и амилопектине. Настоящий обзор посвящен ферменту α-амилаза, который составляет основную долю ферментов на мировом рынке и находит широкое применение в разных отраслях промышленности, таких как пищевая, текстильная, бумажная, крахмалоперерабатывающая, где он полностью заменил химический гидролиз. Amylases are a group of enzymes that are widely distributed in microbial, plant and animal kingdoms. They degrade starch and related polymers to small oligosaccharides. By substrate specificity, amylases are classified to α-, and β- amylases, which catalyze the hydrolysis of glycoside bonds in amylose and amylopectin. This review focuses on the microbial α-amylase, which has potential application in a wide number of industrial processes such as food, textile, paper, starch processing, where enzymes have completely replaced chemical hydrolysis.

Currently, all areas of society are moving toward the mass use of information systems and technologies. Many countries are introducing information systems into the educational process. Every modernteacher should be fluent in information technology. In this way, it helps to increase student motivationfor the class. Changing the system of relations between the teacher and the student, the content, thestructure of their activities, they affect their motivational emotional environment. The use of informationand technological means allows you to turn the biology lesson into a fascinating and productive lesson.The article considers effective methods of using electronic educational resources and capabilities ofeducational platforms in the conditions of transition to distance learning in accordance with the requirements of the state program “Digital Kazakhstan”. It is emphasized that when teaching students, it is important to use effective modern methods and techniques, as well as visual and auditory elements insteadof methods and approaches that make students dependent on the textbook and limit them to what theteacher teaches. The effectiveness of using videos in biology classes was studied. Student performanceresults are given on the research paper. In particular, the use of video materials during classes allowsstudents to convey the necessary information as accurately as possible, and students, due to their modern capabilities and features, better absorb the material in this way. The results of questionnaires fromdifferent regions on the effectiveness of videos were discussed and analyzed. Thus, the study revealedthe necessity of using videos in biology lessons to facilitate students’ learning and their effectiveness inthe learning process.Key words: information technology, methods, videos, experimental, control, performance,creativity.
