Enhancing the Skill of Geometric Prediction Using Dynamic Geometry

This study concerns geometric prediction, a process of anticipation that has been identified as key in mathematical reasoning, and its possible constructive relationship with explorations within a Dynamic Geometry Environment (DGE). We frame this case study within Fischbein’s Theory of Figural Concepts and, to gain insight into a solver’s conceptual control over a geometrical figure, we introduce a set of analytical tools that include: the identification of the solver’s geometric predictions, theoretical and phenomenological evidence that s/he may seek for, and the dragging modalities s/he makes use of in the DGE. We present fine-grained analysis of data collected during a clinical interview as a high school student reasons about a geometrical task, first on paper-and-pencil, and then in a DGE. The results suggest that, indeed, the DGE exploration has the potential of strengthening the solver’s conceptual control, promoting its evolution toward theoretical control.

Case of Actualizing Geometry Knowledge in Abstraction Thinking Level for Constructing a Figure

The purpose of studying geometry is for the development of student thinking, able to abstract and reason, against concepts in the object. Note on some study results that the combination of the student's conceptualization process and knowledge of geometry are a source of barriers to their learning. This study aims to investigate how students actualize their geometry knowledge for the development of thinking to the level of abstraction. Investigations on input, internal processing, and output. This study was conducted on high school students use questions regarding object and product of thought in geometry thinking at analysis and abstraction level. Based on study findings, students actualize their knowledge through figural aspects then developed into the conceptual aspect, and the two aspects are integrated with the relationship between properties. There is a mathematical connection to the integration process. However, because most students' understanding of geometry knowledge is still prototypical figural concepts, so there is an interaction issue between figural and conceptual aspects, namely the validity of relationship between properties. Therefore, students learn geometry in order to investigate the connections between objects and properties as a whole.

Teacher's Specialized Content Knowledge on the Concept of Square: A Vignette Approach

In learning geometry, the discussion about the definition of quadrilateral is a material that is difficult and not easily taught by the teacher. This study aims to explore the teacher's specialized content knowledge about square. This is a descriptive-qualitative research. The process of selecting subjects begins with searching prospective subject data according to the level of the teacher through a portfolio of 82 teachers in South East of Sulawesi: (33 First Teachers, 33 Young Teachers, and 16 Intermediate Teachers). The research subjects consisted of three teachers, namely: First Teacher, Young Teacher dan Intermediate Teacher with score > 50. Data were taken using vignette. The results show that there is a difference when the teacher is asked to define a square with when given a definition of a square. First Teacher is accurate when given a square definition with the symmetry and diagonal axis attributes; the side attribute is not accurate in giving arguments to the square definition. Young Teacher is inaccurate when given the definition of a square with side and angle attributes; accurate with symmetry and diagonal axis attributes; but it is not accurate when given a square definition. Regarding attributes of side; Intermediate Teacher revealed that the side and angle attributes are inaccurate but accurate with the symmetry and diagonal axis attributes but do not appear / are not used when asked to define a square. Specialized content knowledge First Teacher is better because it has been able to reconstruct concepts from a square, but Young Teacher and Intermediate Teacher are still influenced by concept images and figural concepts.

What does the concept of affordances afford?

Gibson once suggested that his ecological approach could provide architecture and design with a new theoretical basis. Erik Rietveld takes up this suggestion—the concept of affordances figures prominently not only in his philosophical and scientific work but also in the design practices he is engaged in. However, as Gibson introduced affordances as a functional concept, it seems ill-suited to capture the many dimensions of our lived experience of the (manufactured) environment. Can the concept of affordances also take on the expressive and aesthetic qualities of artifacts and buildings?

Clean Bandwidth Improvement of MPWM Encoding Method for RF All-Digital Transmitter

In radio frequency (RF) all-digital transmitters (ADTs), pulse encoding methods are often used to generate the RF signal of one or several bits, which introduces a large amount of quantization noise (QN). The QN results in a limited clean bandwidth (CBW), which increase the design difficulty of the analog filter significantly. To solve this problem, an optimized mapping pulse width modulation (MPWM) encoding method is presented in this brief. Based on the QN analysis, the concept of noise figure (NF) for MPWM is introduced. Meanwhile, the formulae of the intermedia frequency (IF) and RF QN power in CBW are derived. Then, in the mapping of the IF signal to the RF pulse, the optimized RF pulses are searched by the NF calculation and comparison. Experiments results show that, compared with original MPWM method, the CBW of proposed method is increased by more than 3 times, and it is superior to the other reported approaches.

<i>Ekphrasis</i> in Four Poems About Urns and Vases

In this interdisciplinary article, we apply the concept of the rhetorical figure of <i>ekphrasis</i>. We will show, in a first instance, that it can be understood as any type of description serving to bring to the reader’s eye something that is distant; however, with the passage of time, this rhetorical figure will be understood in a more complex way, that is, a type of description that targets only and exclusively artistic objects. This new conception will imply that <i>ekphrasis</i> will change from a simple figure that performs a “mimesis of nature” to a rhetorical figure that performs a “mimesis of culture”. Next, we will analyze poems by four poets (Theocritus, Greek, John Keats, English, Alberto de Oliveira, Brazilian and Wallace Stevens, American), each of whom describes a specific sculptural object, either a classical Greek urn, with ornaments or a common, bare jar. We show that there are modifications of the descriptive look, from a classical figuration, through the romantic, and the Parnassian, to the parodic, in the modernist or postmodernist conception, which, using a readymade, in Marcel Duchamp’s sense, deconstructs the relation between the artistic object, the poet and the reader, and thus implies the dismantling of the traditional convention of the rhetorical figure of <i>ekphrasis</i>.

Los paisajes del yo reminiscente. Andrés Neuman, Eduardo Mendoza y Muñoz Molina

This article aims to study the literary relationship between time and space as a narrative construction of discursive conscience. To that end, three novels have been analysed: Fractura by Andres Neuman (2018), El rey recibe by Eduardo Mendoza, and Ventanas de Manhattan, by Munoz Molina (2004). Embracing the concept of figuration, two main textual axis have been established, namely, the alienation of foreign view, and the fabulation of memory. Through those focuses the power of spatial resemantization is explained based on two essential dialectics (inside/out and presence/absence) that cross these three oeuvres. In doing so, the semiotic approach to spatiality has evidence how the formalist deautomatization and dialogism, together with postmodern reification have a meaningful impact on the structural and hermeneutics characteristics that create the personal discourses of three reminiscent selves.

ETNOMATEMATIKA BATIK JONEGOROAN DITINJAU DARI ASPEK LITERASI MATEMATIS

Mathematical literacy and ethnomatematics are two main ideas to determine the role of mathematics in everyday life. Mathematical literacy is an idea that focuses on mathematical and social requirements that can reflect a person's competence in mathematics, while ethno-mathematics emphasizes the competence of people developed in different cultural groups in everyday life. This research focuses on the Jonegoroan batik culture (batik typical of Bojonegoro Regency) because no previous researchers have studied it, especially about ethno-mathematics and mathematical literacy. The purpose of this study was to describe the ethnomatematic form of Jonegoroan batik in terms of mathematical literacy aspects, namely aspects of the content, context, and mathematical processes. This type of research is qualitative research with an ethnographic approach. Data collection was carried out by means of participant observation and interviews. The instruments used were observation sheets, interview guidelines, and research note sheets. The data analysis technique used triangulation. The results of this study indicate that based on ethnomatematic studies on Jonegoroan batik, several mathematical concepts can be found, namely the concept of geometric transformation, two-dimentional figure, and graphs of trigonometric functions. Based on these studies, the activities carried out by Jonegoroan batik craftsmen fulfill the aspects of mathematical literacy. Thus, Jonegoroan batik can be used as a medium for learning mathematics.

666

The purpose of this augmented lecturing Knowledge Module is to discuss the concept of the numerical figure “six hundred sixty-six” found in the biblical book of Revelation (13:18). It is said to be “the number of the beast”—a monstrous, multi-headed creature of the apocalypse. In the public imagination, “666” has long been associated with two, supposedly interrelated, entities: “the Antichrist” and the biological son of Satan. In the view of biblical scholars, however, these associations are false. Rather, the number 666 is a numerological reference to a first-century Roman emperor who had harshly persecuted those who would come to be known as Christians.

SOCIOLINGUISTIC CONCEPTS OF K.MUKHAMEDZHANOV

The article deals with the socio-linguistic concept of eminent writer, playwright and translator Kaltai Mukhamedzhanov in the field of state language status, its role as mother tongue, the normalization of the literary language, the purity of the language, language culture, language ecology, language policy. These problems are analyzed in the article dividing them into three areas. The first is the problem raised in the writer's dramatic works in the field of language purity and its ecology. The second is the writer's statements and concepts regarding the dramatic language of writers, the stage language, the scope of the actor's use of the language on stage, and the Director's responsibility for the language culture. The third is sociolinguistic concepts of a public figure regarding the role and significance of language in society, in the sphere of language policy, and in the development of language as a state language in the territory of our Republic.

This study aimed to determine the worthiness of Geoboard media and to identify the students' mathematical understanding ability after the implementation of Geoboard media in learning mathematics at grade IV SDN Serang 11. Geoboard media is a tool for teaching mathematics at elementary schools to embed the concepts/geometry, such as introducing plane figures, instilling the understanding about the concept of plane figures, and determining the area and perimeter. The method of this research was Research and Development (R&D) with the stages of problem analysis, data collection, product design, design validation, design revision, and limited product trials. Based on the results of the study, it can be concluded that Geoboard Media which was designed like a chessboard was developed based on the validation results with the score reaching 90% from material experts, 88% from media experts, and 93,5% from students’ responses. These results were categorized as Very Appropriate. Using Geoboard media for learning plane figures was considered to be effective to enhance students' mathematical understanding as it was obtaining that the average score was above the KKM (81.75%). After conducting several stages of validation, the final product of Geoboard learning media was considered to be very suitable, efficient, and attractive to be used as a learning media for mathematics learning, especially for plane figures materials, at grade IV SDN Serang 11.

Equine-assisted therapy, health and sports: figurations of the practice in the state of Rio Grande do Sul, 1970-2000

Based on the theoretical assumptions of Norbert Elias, we sought to understand the figurations of equine-assisted therapy in Rio Grande do Sul from 1970 to 2000. To this end, the research corpus consisted of official documents, newspapers and magazines. Based on the concept of figuration, the documentation analyzed demonstrated technical-scientific elements linked to the fields of healthcare, education and horseback riding, coming from equestrianism and shared in the practice of equine-assisted therapy. The interrelations established between these different areas allowed the practice to take on attributes and representations emanating from the equestrian world. Thus, other figurations were developed in the field of equine-assisted therapy involving relationships between military and civil entities.

How (and why) to determine NMR spectrometer’s noise figure?

Abstract In the last decade or two, it seems that the trend of technological advance in NMR spectroscopy cannot follow the trend of desire to measure NMR samples with gradually lower response signals. Recently, an accurate noise model, based on the concept of noise figure, of the most sensitive part of the NMR spectroscopy system from the aspect of noise, which is its probe-to-spectrometer receiving chain, was introduced. The main purpose of this model is to optimize the used NMR spectroscopy system and, ultimately, enable measuring NMR samples with even lower response signals than the ones measured today. All the parameters of the NMR spectroscopy system, used in the introduced model, can be easily measured using vector network analyzers and noise figure meters, or can be found in the datasheets of the respective elements, except the spectrometer’s receiving chain noise figure. In this contribution, the process of spectrometer’s receiving chain noise figure measurement, performed using the Twice Power Method, is described. A block diagram representation of the spectrometer’s receiving chain is presented here, as well as its approximative model. The respective noise figure measurement results, which are also presented, explain the general tendency of using the mid-range of the spectrometer’s gain control level when performing the actual NMR measurements.

Fieldworking the relational complexity of organizations

PurposeThe purpose of this paper is to present researcher's reflexive writing about emergent events in research collaborations as a way of responding to the process-figurational sociology of Norbert Elias in the practice of organizational ethnography.Design/methodology/approachDrawing parallels between Norbert Elias' figurative account of social life and auto-ethnographic methodology, this paper re-articulates the entanglement of social researchers in organizational ethnographic work. Auto-ethnographic narration is explored as means to inquire from within the emerging relational complexity constituted by organizational dynamics. Writing about emergent events in the research process becomes a way of inquiring into the social figurations between the involved stakeholders; thus nurturing sense-making and increasing the awareness and sensitivity of the researcher to her own entanglement with the relational complexity of the organization under study.FindingsIn the paper, we argue that the writing of auto-ethnographic narratives of emergent field encounters is a process of inquiry that continuously depicts the temporal development of the relational complexity in organizations. Viewing that from the perspective of Elias' concept of figuration, we find a common commitment to the processual nature of research processes, which insists on moving beyond objectifying empirical insights.Originality/valueThis paper encourages awareness of the interdependency between ourselves as social researchers and field actors as we engage with the field. It moves beyond simplifying the ethnographic research agenda to that of “studying” and “describing” organizations. It offers unique insights into the organizational context, and increased sensitivity toward the social entanglement of the experiences that we, ourselves, as researchers are part of.

Direct identification of Borobudur temple artefacts for learning flat shapes concepts

Understanding concepts is important in learning mathematics, one of them is learning geometry. The concept of geometry is closely related to daily life, so that introducing directly the object of geometry is expected to facilitate the understanding of geometry concepts for students. This research is a descriptive qualitative research. The purpose of this study was to determine student understanding in studying geometry by directly identifying Borobudur temple artefacts. The subjects of this study were 3 students of class VIII SMP. The instrument in this study was the researcher herself as the main instrument guided by a concept understanding test and interview guidelines based on valid and reliable tests. Data were collected through the provision of pre-test and post-test about understanding the concept of a flat figure which includes 7 indicators and accompanied by interviews as supporting data. The results showed that directly identifying the Borobudur temple artefacts can be used as an alternative to studying the concept of flat wake. The weakness of this study is that the three subjects have not been able to answer the problem in indicator 7, which is about developing sufficient requirements or necessary requirements from the concept of a flat figure. This can be a material or material that can be used as future research.

The Second Violin Consert Of Bela Bartok In The Context Of Genre Development

Relevance of the study. One of the leading instrumental types of the concert is the violin concerto, presented in the first half of the twentieth century by almost 500 works. An important stage in the evolution of the genre during this period were the violin concertos by the outstanding Hungarian master Bela Bartok, which were firmly in the repertoire of modern performers. The second concerto (1938), dedicated to a friend of the composer, the famous Hungarian violinist Zoltán Székely, was first performed by him on May 29, 1939 in Amsterdam. Widely covered in musicological literature, however, it has not yet been considered in a genre context.Main objective(s) of the study is to find out the correspondence of Bartok’s Second Violin Concerto to the general trends in the development of the violin concerto in the first half of the 20th century and to reveal individual features of the interpretation of the genre.Methodology. In the course of the study, the following methods were used: historical – to trace the history of the development of the violin concert genre in the first half of the twentieth century; systemic – for grouping concerts of the time according to various parameters; comparative – to compare individual samples of the genre; structural-functional, intonational -dramatic, semantic – for a comprehensive analysis of the Second Violin Concerto of B. Bartok.The main results / findings and conclusions. The development trends of the violin concerto genre in the first half of the twentieth century, systematized for several parameters: stylistic features, compositional structure, imaginative concept and interpretation of the genre are considered. According to the specified parameters, the Second Violin Concerto of B. Bartok was analyzed, the correspondence of the revealed features of his organization to the main trends in the development of the violin genre was clarified, and the manifestation of individual features of his interpretation was emphasized. The circumstances of the creation of the Bartok concert are highlighted and the conditionality of the figurative concept of the work is proved. The patterns of musical dramaturgy were revealed by analyzing verbal remarks reflecting the leading figurative spheres: heroic (Risoluto), lyrical (Calmo) and scherz (Allegro scherzando). The compositional features of the concert are characterized, the updating of the three-part model typical of the genre is justified due to the introduction of the variational principle, operating at all levels of the organization of the whole. Identified folk influences in the style of Bartok’s violin concerto, in particular, the assimilation of the mode-intonational and rhythmic elements of the styles of parlando rubato and verbunkos. The interaction of solo and orchestral parts is traced; an expansion of the range of performing techniques of playing the violin is noted.

"Don't worry": Figurations of the child in a Swedish parenting advice column.

Materials such as popular books, magazines, and newspapers have historically been important for the circulation of psychologists' and psychiatrists' expertise in the public sphere. In this article, I analyze an advice column published in the Swedish parenting magazine Vi Föräldrar [Us Parents], featuring the child psychologist Malin Alfvén. Drawing on the concept of figurations (Castañeda, 2002), denoting the process of outlining and defining an entity, I show how the expert framed the child-related problems brought up in the submitted letters as transient and a normal part of children's development. In fact, most problems were considered beneficial for both parents and the child. Instead of interpreting children's behavior through a medical framework, Alfvén's explanations drew on 3 naturalizing figurations of the child: as being one of several kinds of children; as going through phases and ages; and as being a unique individual. For instance, a child could be rowdy and temperamental because he was a willful kind of child, not because, as suggested by some parents, he suffered from a neuropsychiatric disorder. I conclude by contrasting these findings to the claims made by some scholars that "psy" experts have contributed to an increasing medicalization of childhood as well as to a framing of children's development as overwhelmingly determined by parents' care.
