How do we keep hot drinks hot and cold drinks cold? Companies such as Tervis, YETI, and Thermos spend their time researching and designing products around that very question. In this lesson, students will discover, through mathematical modeling, which materials provide the best insulation and be tasked with designing their own insulator. This lesson has been designed at two different levels for students from grade three through high school with an optional extension activity for more advanced students. Students will use technology to explore the rate of change of the temperature of hot water over two minutes using different insulation materials. After this exploration, students will use the data they have collected to determine the best materials for designing their own insulator. This insulator will then be judged based on the ability to keep a hot drink hot and on the aesthetic value.

The subject of the study is the relationship between the methodology of teaching the Ukrainian language as a foreign language and phraseological material, which activates the various levels involved in mastering the linguistic base, namely motivation, memory, cognition and others. The article deals with the problem of bilingualism in Ukraine, considers the problems of teaching foreign students the Ukrainian language in terms of partial bilingual everyday communication, suggests ways to solve these problems. The classification of modern strategies used in language learning is considered. We also considered the advantages of the communicative-cognitive approach to learning the Ukrainian language. The research methodology consists of theoretical and practical principles of observation, recording and evaluation of activities in the system of teacher – students, taking into account the different conditions of linguistic and non-linguistic reality. The purpose of the study is to clarify the peculiarities of the use of phraseological units in the framework of work with foreign students, taking into account the bilingual situation in some parts of Ukraine. The article deals too with linguistic and methodological aspects of the study of phraseological units concerning with the work at the lessons of Russian as a foreign language. Phraseological units possess aesthetic value, so it is often included to the training material. The interpretation of them occurs on pretextual work level. The actual material of the article has about 50 different levels of language units, the selection of idioms was carried out in the presence of words with temporal meaning. An idiom is a linear sequence, representing the aesthetic value thanks to the meaning hidden in it. Words, in idiomatic expressions, creating a special sense, come in a variety of relationships – synonymic, antonymic, of kind and type ones etc. Inside the words can occur shifts of meanings such as metaphorical, metonymic. The syntax structure of idioms can be different from a phrase to sentences with different punctuation. Learning understanding and practical usage of Russian phraseological units lead to the development of students not only objective semantic and associative evaluation of the various acts or objects, but also to the ability to implement the same idea through units of different levels of language and speech formulas, which are composed of elements with imagery. The conclusion of the study. We have considered the classification of modern strategies used in the study of Ukrainian as a foreign language. The advantages of communicative-cognitive approach to learning the Ukrainian language are described. Practice shows that motivation and mnemonic techniques are important in learning. The phraseological layer of vocabulary is a very important culturological factor in the process of learning a foreign language. We can see further prospects of our research in a detailed consideration of all the tools of communicative-cognitive approach to the study of language as a foreign language.

Many researchers have stressed the embodied nature of mathematical understanding. Here we explore how embodied knowledge may evolve as students learn a basic calculus concept: the rate of change. We examined undergraduate students with different levels of calculus knowledge working in pairs to model the rate of change in an everyday phenomenon. Our findings revealed substantial differences between advanced and introductory students in how they represented the rate of change with their speech and gestures. In particular, the advanced students’ embodied representations showed alignment with the formal symbolic process of integration and reflected more advanced ways to coordinate the relation between multiple changing variables. For example, advanced students often made gestures that represented a “disk” when explaining how the rate at which water rose in a bottle was related to the change in height. Thus, both introductory and advanced students demonstrated embodied knowledge through speech and gestures, but the advanced students constructed different concrete representations that reflected an advancement in their embodied knowledge. Our findings are relevant to calculus education and to the study of gestures in mathematics learning.

This study has primary focus to analyze the aesthetic layout of a newspaper with a mathematical approach, which refers to some methods of Birkhoff’s aesthetic measurement developed by David Ngo Chek Ling, et.al. Ngo developed a method of measuring the aesthetic layout that can be used for various design purposes, especially for a computer interface design. Measurement method that he developed refers to the principles of design aesthetics, such as: the principle of balance, the principle of sequence, the principle of unity, and the principle of equilibrium. Birkhoff aesthetic measurement method was used as final analysis to determine the value of aesthetic layout. In this study, some national and local media were selected as samples to determine and assess the aesthetic layout. Based on data analysis, Birkhoff aesthetic measurement method can be applied to measure the aesthetic value of the newspaper layout mathematically.

The article focuses on Mikhail Yasnov’s poetry that is addressed to children of different ages, from younger preschoolers to older schoolchildren. Yasnov’s poetry is viewed as a corpus of texts united by several general principles: among them are the harmony of childhood and the child’s trust in the world. Another unifying principle is poetic dialogue, manifested at different levels of literary texts: from characters and imagery to metatextuality and the author’s consciousness. Dialogue in this paper is understood as overcoming a single point of view, an attempt to go beyond the personal I motivated by the attention to the Other. Yasnov’s poetry focuses on the search for similarities and differences between the phenomena of reality as it presents many voices and life positions. The concept of dialogue has great moral potential in children’s poetry as it contributes to the formation of empathy and development of self-knowledge in children. The aesthetic value of dialogue lays in the enrichment of the thematic and figurative structure of the lyrics.

This paper considers the fundamental problem of artificial lighting in various types and scales of industrial facilities, focusing on exterior lighting design solutions. There is a lack of interest from investors, customers and society in high­quality lighting design for industrial facilities in Russia, which in many cities are very imaginative structures, practically unused in the evening. Architectural lighting of various types of installations is illustrated with photographs. The purpose of the article is to draw attention to the aesthetic value of industrial structures, provided not only by the architectural, but also by a welldesigned lighting solution.

Considers the aspects of architecture as a language able to express the current state and to prophetically indicate the upcoming changes. The aesthetic value of a construction cannot be perceived just as a separate entity, but it can be cognized in the context and not only a visual one, in space. It is necessary to see the entire complex of the accompanying phenomena, all the flow of the unfolding metaphors and values. In the model in view the figure of the author-creator must be reconsidered as no longer conforming to today's reality. The development of the Stalinist Empire style, as well as its transformations, is considered as one of the specific phenomena in the history of well-known constructions

<em>The process of folding clothes is one of the activities carried out in the laundry business or household. The activity is fairly easy but many people are still lazy to do it. As a result, clothes that have been washed will fall apart in certain rooms, thereby reducing the aesthetic value of a home. Semi Automatic T-Shirt Folding Machine is the right solution to make folding clothes easier and more time efficient. This tool is equipped with a servo motor that moves the folding board that has been designed in such a way that the user only needs to manghandle the shirt just once and simply push one button then the shirt will fold itself and will be neatly arranged through the clothes stacker board. The PID method is applied to DC motors that move under the clothes folder so that the buildup of clothes underneath will not be pressured upward when the clothes are piled up when they are folded. Ultrasonic sensor will measure the right height between the clothes with the door opening the stacking clothes with kp = 1, ki = 0.1, kd = 0.5 for thin clothes and kp = 5, ki = 1, kd = 2.5 for thick clothes so that the movement of the motor can adjust its speed . This tool can fold one shirt in 16.83 seconds 11 seconds faster than folding clothes manually</em>

This study aims to examine the decorative types of Gorontalo karawo fabrics in aesthetic and symbolic elements. Researchers want to know as made in the research design, aspects that are present in the decoration of fabrics in aesthetic and symbolic elements. This study uses a number of related theories to get results, and as a determinant, the authors use aesthetic theory, as well as historical approaches. With this theoretical basis, the author seeks to describe the aesthetic aspects and symbolic meanings that exist in Gorontalo karawo fabric. Through the data collection of the chosen motif and provide a classification of motives, the part is used as a reference for research material. The results showed that Gorontalo filigree had an aesthetic value consisting of unity formed from the overall decorative motifs displayed, complexity formed by complexity in the manufacturing process, and intensity of seriousness in the manufacturing process or the impression displayed on the filigree motif. The aesthetic form also reflects the diversity of meanings for communication, such as the symbol of a leader with his noble instincts, a symbol of cultural cooperation, which is worth maintaining, and ideas about nature conservation. This research proves that the decoration in Gorontalo filigree cloth (karawo) does not only act as a visual value, but also as a communication of cultural meanings and social status. Of all these distinctive motifs show a relationship between humans and humans and humans with nature. The influence of culture from the Philippines is also known to have a strong influence on the emergence of the Gorontalo filigree namely manila filigree.

A theory of aesthetic value should help us to make sense of how our aesthetic commitments matter to us as members of collectives. Aesthetic policies endogenous to aesthetic practices are directly justified by the network theory. The chapter looks at what aesthetic reasons we have to adopt exogenous aesthetic policies. Many argue that aesthetic practices deserve public support because aesthetic goods are public goods. A case is made for an aesthetic opportunity principle: larger social groups have reason to foster the aesthetic opportunities available to their members. The principle is applied to arts education and to communication technologies subserving aesthetic exchanges. The chapter ends with a discussion of how aesthetic opportunity interacts with—and can potentially counteract—oppressive social structures.
