The genus Artemisia includes a large number of aromatic plants that produce secondary metabolites with numerous applications in the health, cosmetics, food and pest management sectors. However, ...relatively little is known of the dedicated organs where many of these metabolites are synthesized and accumulate. In this context, the aim of this paper was to identify the essential oil-secreting tissue of Artemisia abrotanum L. (Asteraceae) popularly known as southern wormwood. The morphology of its secretory tissue was studied using optical microscopy, transmission electron microscopy (TEM) and scanning electron microscopy (SEM). For the first time, secretory structures composed of stalked bicellular glands have been identified in the leaf sinuses on the abaxial side of the leaf blades. These secretory structures have not been described before in vascular plant taxa indigenous (native or naturalized) to Romania, but were reported in other Asteraceae species worldwide.

The present paper reprezent an analysis of the characteristic features of naţional folklore that allow the cultivation of the musical feeling in students through the folkloric musical discourse ...wilthin the music education lessons. Through popular music, we offer the opportunitz tho reflect on sone earlz stages in the evolution of musical folklore. This fact can lead us to some important aspects regarding the origin of popular music, the discoverz of the charactristic features of the musical language. By cultivating musical frrlings in students during music education classes, we develop a favorable behavioral attitude towareds Romanian spirituality, expressed in its multiple historical valoues. On this value component, we take into account the human perceptive capacity, and the forms of musical manifestation. The students will be trained in music education classes, through the folkloric musical discourse, which will allow a direct development of the students personality in the national spirit.

Pre-adolescent kids love stories and do not accept deviations or interruptions in the narrative line. They are connected to "life" and immediately condemn the lack of sincerity. The very young ...audience is different from an adult or teenage audience. It must be understood and educated. "Children are the future" is not a cliché but a reality. If the psychological mechanisms and springs that make them work are analysed and used intelligently in a show with a complex universe, theatre can create a leap in consciousness for new generations. Building techniques must be developed and improved in such a way that the performing arts regain their vital role in the rebirth of a nation.
The article examines the creation of Elena Samburic, being centered on various branches of fine arts – painting, graphics, sculpture, decorative arts, art-object etc. An important role is reserved ...for the concept of the given topics, focused on various dimensions (general-human ideas, man’s relationship with the universe, the issue of procreation, the world of childhood, magic etc.) and the technical-plastic options preferred by the artist. Her work denotes an original artistic thinking, a specific vision on the world exposed in a language of decorativeabstract nature and in various techniques obtained from her own multiple experimental searches. Her creation through the originality of artistic thinking, through the expressiveness of the used plastic language brings to the public’s attention new stylistic landmarks, thus contributing to the enrichment of the national cultural heritage.
Didactic strategies combine all the elements of the educational process, being a way of combining and chronologically organizing the set of methods and means chosen to achieve certain didactic ...objectives. This way,, the didactic strategy is expressed in organic units of methods, procedures, educational means and ways of organizing/achieving the learning process, i.e. head-on, in groups and individually Potolea, D. The teacher and the strategies of learning management. Bucharest: Academy Publishing House, 1989, p. 146. From the given perspective, we would like to mention that the didactic strategy unifies, integrates and brings together learning tasks with learning situations, creating a complex and logical system structured by means, methods, materials and other educational resources aimed at achieving certain objectives, which constitute a extremely necessary aspect in any pedagogical action, which finds its central place in the educational process. This is due to the fact that the design and organization of a lesson takes place in close connection with the strategic decision of the teaching staff and, therefore, it is designed as a complex didactic scenario, in which the actors of the educational act - of teaching-learning are involved, the conditions in which it is carried out, the objectives and the proposed methods. This way, the strategy determines the most appropriate, logical and efficient methodical itinerary for approaching a concrete teaching-learning situation, avoiding some errors, risks and unwanted events that may appear in the activity of the teaching staff.
The application of interdisciplinarity in primary education has many benefits in the young students’: the development of cognitive, communication and social, in-depth understanding of knowledge, the ...understanding of the connections between different fields of knowledge, the development critical thinking, authentic learning skills that develop transversal skills, the development of essential skills, communication skills, learning issues, where learning content and activities are integrrated across multiple disciplines or fields of study with the aim of developing more complex skills either through learning themes or teaching protejects. The teaching-learning-evaluation relationship, viewed a necessity and a decisive condition of modern education.
Involved in the process of formation of the personality and of the self-formation, aesthetic education aims at the development of the ability to correctly perceive and understand the beauty in the ...real life, the formation of aesthetic consciousness, aesthetic taste and sense, the need and possibility to participate in the creation of beauty in art and in life. Through the aesthetic education, we aim to prepare pupils for the act of valorization-reception-assimilation and the act of creating aesthetic values. The article presents ways and strategies to contribute to the development of the competence of self-instruction of pupils, in terms of education for beauty, so that they become efficient and autonomous in daily school activities, assume responsibilities, develop skills inside and outside the classroom. The conclusion of this article is that by encouraging pupils to be independent and responsible in their learning, they will become adults with motivation for lifelong learning.
