Teachers’ Adaptation In The Use of Instructional Media In Teaching English as A Foreign Language at Junior High School In Sungai Penuh

In Indonesia, the number of English learners keep growing. Different methoods and effectiveness in teaching English has been experimented to get a better achievement. But still the systems, methods and techniques have some lacks and still need to have improvement and innovation to solve the problems. The problems are different in every schools, one of the problems currently faced by teachers was the new adaptation to the situation where schools activity turned to online activity. Teachers have to adapt into the new situation where all activities need to be handled through online activity and it becomes the problems for most of teachers who had no preparation and facilities during that time. Thus, the way English teachers adapt intstructional media and how teachers utilize and apply the instructional media especially audio visual media will be the main focus of this research. The researcher used suervey as a research design. There will be five junior high schools included in this study. There are 10 English teachers from different junior high schools in Sungai Penuh. The researcher only chose the junior high schools which are A-accredited. The researcher used questionnaire and interview as the instruments of this particular study. The researcher employed quantitative and qualitative data. The quantitative data were taken from close-ended questionnaire while the qualitative data were taken from interview result. The data analysis results shows that the teachers at Junior High Schools in Sungai Penuh used variatif instructional media in teaching. The researcher found types of audio visual instructional media mostly used among the teachers to improve student’s skills are audio recording (9,4) (hints,stories,conversation) and Videos (8,4) (documentaries,tutorials,teaching) which is very good response. The most used to improve speaking is Song (6,1) and Picture (7,3) teachers have good response towards them. Next, for reading is picture (8,8) and last to improve writing skills song (6,4), picture (6,8), flashcards (5,9), charts (5,7), videos (5,1) also have good response. Audio drama, movies, TV programs, news broadcast are the media that have bad response. Additionally, The most used hardware among the teachers are whiteboard (9,7) printed paper (9,1), smartphone (8,4), computer /laptop (7,7). Radio, recorder, CD player are get low response from the teachers. In adapting instructional media, teachers adapting from concrete object surround the classroom and schools, teachers also utilze digital devices like smartphone and software application like Whatsapp and Youtube. Moreover, teachers adapting the existing media and combined with other media that created by their own to assit them in delivering the materials. In addition, Teachers at five different junior high schools in Sungai Penuh have good views towards instructional media.

If students can present concepts in the multiple representations form (verbals, symbols, pictures and concrete objects) and know the structural, students are said to have understood the concept. Props are media that contain concepts in it. Maximizing the use of prop can be related to the characteristics possessed by students. There are different characteristics in students during the process of processing information to generate ideas, especially characteristics in the form of gender (male and female) and cognitive style (Field Independent (FI) and Field Dependent (FD)). The results of the integration of the use of props and the characteristics contained in students to produce a series of activities to maximize the use of props in learning are: (1) Adjusting and understanding the concepts in the props in two other forms (multi-representation), for example with verbal forms and symbols. or in the form of pictures and symbols; (2) Get used to girls to re-explain or justify the three forms of representation of the concept; (3) Ensuring girls can draw pictures of concepts being constructed; (4) Ensure that boys are aware of and reflect on their knowledge and experiences; (5) Ensure that male students get an image of the concept that is being constructed. The results of this training were responded well by the participants and increased the interest and motivation of teachers in creating simple teaching props and using them optimally.

Metaphor and the Material Object in Moscow Conceptualism

Discussions of conceptual art both East and West have focused on the notion of “dematerialization” of the artwork and the substitution of “art as idea” for concrete works of art. Yet such an approach oversimplifies the role of materiality in works of conceptual art generally and underestimates the transformative role of the concrete object in early Moscow conceptualism in particular. An examination of the Nest, an influential group of artists active from 1974 to 1979, as well as other analytical conceptualists who highlighted materiality in their unofficial art practice suggests that their use of concrete objects and realized metaphors revolutionized late-Soviet unofficial art, moving it from an outdated modernist model of artistic autonomy to a more dynamic and engaged postmodernism. Their previously underappreciated contribution to the evolution of global conceptualism expands our picture of the movement as a whole and provides needed context for late-Soviet art and the post-Soviet period that followed.

The Role of Props in Promoting Imagination during Toddlerhood

Knowing how children become oriented to imaginary play can help educators in centres better support development. But how this begins in the first years of life is not well understood. How toddlers transform through their imagination concrete objects (such as play accessories, figurines, and books) to become props in play (placeholders and pivots) for conveying meaning, remains low. Drawing upon cultural-historical theory, the study reported in this paper sought to understand the role of props for supporting the development of imagination during toddlerhood. Four toddlers aged 1.9–2.1 years from an early childhood centre in Australia were followed as they used objects as props during imaginary play. The study design was an educational experiment of a Conceptual Play World (CPW): a collective model of practice for developing play and imagination. Digital data of the CPW being implemented in the toddler room were collected through video recordings over two months. Thirteen hours of data were collected and analysed using the Vygotskian concepts of play and imagination. The findings revealed that through differentiated use of props, toddlers made transitions from the embodiment of the experience to sharing an intellectual and abstract space where objects became props in play, suggesting the genesis and development of early forms of imagination. The outcomes of the study advance theory and inform practice about the early development of imagination in toddlerhood.

What can size tell us about abstract conceptual processing?

Embodied cognition theories propose that abstract concepts are grounded in a variety of exogenous and endogenous experiences which may be flexibly activated across contexts and tasks. In three experiments, we explored how semantic size (i.e., the magnitude, dimension or extent of an object or a concept) of abstract (vs concrete) concepts is mentally represented. We show that abstract size is metaphorically associated with the physical size of concrete objects (Experiment 1) and can produce a semantic-font size congruency effect comparable to that demonstrated in concrete words during online lexical processing (Experiment 2). Critically, this size congruency effect is large when a word is judged by its semantic size but significantly smaller when it is judged by its emotionality (Experiment 3), regardless of concreteness. Our results suggest that semantic size of abstract concepts can be grounded in visual size, which is activated adaptively under different task demands. The present findings advocate flexible embodiment of semantic representations, with an emphasis on the role of task effects on conceptual processing.

Development of muon scattering tomography for detection of reinforcement in concrete

Inspection of ageing, reinforced concrete structures is a world-wide challenge. Existing evaluation techniques in civil and structural engineering have limited penetration depth and do not allow to precisely ascertain the configuration of reinforcement within large concrete objects. The big challenge for critical infrastructure (bridges, dams, dry docks, nuclear bioshields etc.) is understanding the internal condition of the concrete and steel, not just the location of the reinforcement. Muon scattering tomography is a non-destructive and non-invasive technique which shows great promise for high-depth 3D concrete imaging. Here a method is presented to locate reinforcement meshes placed in a large-scale concrete object. A reinforcement mesh was simulated as two layers of 2 m long bars, forming a mesh. Two layers of the mesh were placed at several distances from each other inside a large concrete block. Previously, we have shown that using our autocorrelation technique for single meshes inside the concrete and using only one week worth of data taking, bars with a diameter of 7 mm and larger, could easily be detected for a 10 cm mesh spacing. The signal for 6 mm diameter bar exceeds the background and becomes very clear after two weeks of data taking. Here we show that we can detect the vertical positions of two mesh layers inside the concrete. This is a very important result for non-destructive evaluation of civil structures.

New trends in the ultrasonic imaging of concrete structures by means of 3D-FMC technology

The novel technologies in ultrasound generation and data processing offer new opportunities for three-dimensional imaging of concrete structures. Especially the Full-Matrix-Capture (FMC) technique with its real-time imaging capability can be successfully utilized for quality assurance in the construction industry. Although, the available testing instruments on the market implement the principle of linear transducer array with its two-dimensional reconstruction of B-Scan images based on the Synthetic Aperture Focusing Technique (SAFT) principle. The Dry-Point-Contact (DPC) transducers utilized in commercially available instruments for concrete testing with their matrix-like layout offer a direct opportunity to implement a three-dimensional Full-Matrix-Capture (FMC) data acquisition cycle. The obtained data can be in real-time processed by 3D-TFM reconstruction and visualized and evaluated three-dimensionally. In the present contribution both state-of-the-art and novel true-3D imaging approaches and data assessment are considered on real concrete inspection objects and the advantages of enhanced data processing with respect to improved information content and easiness of result, interpretation is discussed.

Anxiety, helplessness, and courage

In this essay, I discuss the root and meaning of anxiety before turning my attention to the relationship between anxiety and courage, arguing that courage is often a defense against anxiety: an externalization of an internal crisis. Discourses of courage draw attention away from the true problem of anxiety, rather than addressing it, sponsoring a kind of uncourageousness by externalizing anxiety, transposing it onto concrete and manageable external feared objects. Furthermore, courage and bravery discourses do not accord with the reports of persons who have performed brave acts, who describe their behavior either as forms of service to internalized values or as moments of madness. Contemporary courage discourses reinforce the belief that, in courage, there is a component of the self that is capable of helping the self in times of need. Yet, this helper self is either substantially degraded or missing entirely in the case of anxiety, which is organized around failures of help and consequent experiences of shame and helplessness.

Spatial Ability and Digital Literacy Profiles: Preceding Survey on the Need of Augmented Reality Media in Chemistry Instruction

Students are demanded to be equipped with a sufficient level of multiliteracy to perform 21st Century Skills which include spatial ability and digital literacy. Spatial ability is needed to solve problems in chemistry lessons. In addition to spatial ability, digital literacy is also required to face industry 4.0. This research is aimed to analyze both spatial ability and digital literacy skills along with the media that could help develop the two skills. The research method used is descriptive qualitative method uses a survey to collect the data. This study was carried out on 922 senior high school students from four schools and 35 teachers. Purdue Spatial Visualization Test (PSVT), Likert-scale questionnaire, and closed-ended questionnaire were used as the instruments. The results indicate that 98% of the students are of low category in spatial ability while those showing mid and high category each only consists of 1%. However, in terms of the digital literacy index, the students generally score mediocre. The results from the media need a questionnaire on chemistry instruction to indicate that Augmented Reality-based media is needed both by teachers and students. Therefore, to help improve the students’ spatial ability and digital literacy, a teaching media that visualizes both abstract and concrete objects is needed.

Numerical simulation of elastic buckling in 3D concrete printing using the lattice model with geometric nonlinearity

This paper explores buildability quantification of randomly meshed 3D printed concrete objects by considering structural failure by elastic buckling. The newly proposed model considers the most relevant printing parameters, including time-dependent material behaviors, printing velocity, localized damage and influence of sequential printing process. The computational uniaxial compression tests were first conducted to calibrate age-dependent elastic modulus and yield stress. Subsequently, analyses of the 3D printing process of a free wall structure and a square layout were performed. The model can reproduce the asymmetry of buckling failure accurately and the predicted critical printing height is in excellent agreement with experimental data from the literature. It can be concluded the combined effect of material variability and non-uniform gravitational loading due to sequential printing process resulted in structural failure during 3D concrete printing. Using this model, printing parameters can be optimized and a suitable printing scheme can be devised to improve structure buildability.

A comprehensive strategic partnership of the RF and the SRV: the achieved result or a perspective target?

The author of the article makes an attempt of the conceptual consideration of a comprehensive strategic partnership, a poorly investigated kind of international relations, so far. It is mentioned that different countries, as well as official documents and research-works discuss the features of this status of international relations differently. General theoretical conclusions are applied to the concrete object of the research, i.e., to current Russia-Vietnam relations. The conclusion is that the level of their development does not fully correspond to the content of the term comprehensive strategic partnership. It is emphasized that such a situation interferes with the efficient development of cooperation. The current confrontation of the West with the Russian Federation against the background of the developments in Ukraine affects Russia-Vietnam relations.

Analysis of the Deaf Student's Critical Thinking Skill to Understanding Fractional Concepts Based on Visual and Kinesthetic Learning Styles

Critical thinking skills can train construction students’ knowledge, including deaf students whose learning mathematics content is different from hearing students. This study aims to analyze the critical thinking skills of deaf students to fractional concept understanding in the sub-skills of focus, reason, inference, situation, clarity, and overview. This study type is descriptive with a qualitative approach. Data was collected through critical thinking tests and unstructured interviews to explore students’ test results. The data validity was obtained through time triangulation which was carried out by comparing several test results. This study involved 12 subjects comprising eight students with visual learning styles, three with kinesthetic learning styles, and one with other learning styles. Researchers will not review the other learning styles in this study. The critical thinking test used in this study consisted of questions representing the sixth critical thinking sub-skills. Researchers analyzed the collected data through data reduction, presentation, and conclusion. The results show that in understanding the concept of fractions, the critical thinking of deaf students is influenced by their learning style. Visual learning style students’ activities related to images, while kinesthetic learning style students related to concrete objects around them manipulation.&#x0D; Keywords: Critical Thinking; Deafness; Fractional Concept; Learning Styles

REVIEW MENGENAI PENINGKATAN KUAT TEKAN BETON YANG TERKEKANG SECARA SEMPURNA DENGAN EKSTERNAL NATURAL FIBER REINFORCED POLYMER (NFRP)

Structural strengthening is needed in buildings that experience a decrease in serviceability, inappropriate quality of existing concrete, and unexpected natural events such as earthquakes. One method that has been widely used for structural strengthening is external restraint using synthetic Fiber Reinforced Polymer (FRP). External restraints on concrete can significantly increase the strength and ductility of concrete. The use of Fiber Reinforced Polymer (FRP) material requires a relatively expensive cost and a production process that is not environmentally friendly, so alternative Natural Fiber Reinforced Polymer (NFRP) materials are needed that are environmentally friendly, renewable, and relatively cheaper, such as jute, hemp, cotton, abaca and basalt. This research review aims to determine the behavior of confined concrete with external Natural Fiber Reinforced Polymer (NFRP) and the increase in compressive strength due to confinement. The test is carried out by providing an axial load on the concrete test object which is restrained by NFRP. NFRP restrained specimens are made by wrapping the entire concrete in a circle using natural fibers and adhesives. The results obtained from this research review are the compressive strength of confined concrete using several types of natural fibers such as jute, hemp, cotton, abaca and basalt, it is found that the type of fiber and the number of layers of NFRP affect its compressive strength. NFRP showed a significant restraining effect on increasing the compressive strength and increasing the ductility of the concrete. The increase in strength and ductility will increase with an increase in the number of layers of Natural Fiber Reinforced Polymer (NFRP).

Implementation of augmented reality-assisted learning media on three-dimensional shapes

This research is motivated by the low understanding of students in studying the object of geometry study. The media that had previously been used in the form of a spatial framework made of bamboo or iron turned out to take up quite a lot of space and was not practical to carry in large quantities. Therefore, efficient and practical media are needed to help visualize concrete objects in learning. This research aims to implement Augmented Reality (AR)-assisted learning media on the material of three-dimensional shapes. This study uses an explanatory qualitative method. The participant in this study was one student from one of the junior high schools in the Cirebon Regency. Data collection techniques used are through interviews and documentation. The analysis technique consists of three stages: data reduction, data presentation, and concluding. The results showed that the AR application could make it easier for the student to understand the material and solve the problem of three-dimensional shapes. However, the student still has a little difficulty using the application and is a little confused when identifying the parts of the cube because the image of the shape raised by the application is still not clear. This research implies that AR applications can make students' spatial abilities better.
