Visualização no ensino de Ciências uma perspectiva para a integração de atividades experimentais

Ensinar ciências está diretamente associado a envolver os estudantes em atividades que os auxiliem a compreender modelos científicos abstratos, o que torna as experiências visuais fundamentais no processo de ensino-aprendizagem. Nessa perspectiva, a visualização no ensino de ciências apresenta uma abordagem teórica que busca idealizar os processos cognitivos, envolvidos em atividades que buscam favorecer essas experiências por meio dos objetos de visualização (como, por exemplo, gráficos, tabelas, diagramas esquemáticos). Entre estas experiências visuais podemos considerar as atividades experimentais, bastante difundidas no ensino de ciências, desenvolvidas no mundo concreto e/ou por meio das tecnologias digitais. Pesquisas recentes (por volta dos anos 2000) têm apresentado o contexto de integração de atividades experimentais reais (mundo concreto) e virtuais (tecnologias digitais), frente ao seu uso em configurações isoladas. Os resultados de aprendizagem comparativos têm evidenciado um cenário promissor com relação à integração dessas atividades. Deste modo o objetivo deste estudo foi analisar esses resultados com base na visualização, por meio dos objetos de visualização oferecidos nas atividades das pesquisas. Os resultados encontrados confirmaram nossa hipótese de que a integração se torna mais favorável ao ensino, pois oferece diferentes objetos de visualização que se tornam complementares. Cenário este que não acontece ao usarmos apenas uma modalidade de atividade experimental.

Risco-espetáculo: novas modalidades do risco na era digital / Risk-spectacle: new modalities of risk in digital era

Este artigo tem como finalidade discutir o engendramento do risco-espetáculo enquanto uma nova modalidade de risco e também como vetor de subjetivação na contemporaneidade. Neste sentido, o risco-espetáculo se configura como uma leitura possível acerca de um fenômeno da era digital que tem alcançado enorme popularidade entre o público infanto-juvenil: os desafios do youtube. Muitos desafios se popularizaram ao serem publicados por famosos youtubers, as celebridades da Internet. Como consequência, jovens e crianças passam a reproduzir tais práticas em suas casas. Apesar do caráter lúdico e aparentemente seguro, alguns desafios do youtube implicam em risco à saúde e à vida, sendo enquadrados no rol das brincadeiras perigosas. Estas práticas de risco se desenrolam, na maior parte das vezes, alheias à tutela e à supervisão da família. Isto nos leva a interrogar que modos de governamentalidade operam no ambiente virtual, de forma a gerir condutas que incidem no mundo concreto e que modos de subjetivação estão sendo produzidos a partir destas práticas.
 Palavras-chave: Risco-espetáculo; desafios do Youtube; brincadeiras Perigosas; governamentalidade.

Examining the Efficiency and Effectiveness of Alternative Material for the Interlocking Prefabricated Sandwich Panel

The paper shows the effective utilization of non-degradable waste material like the hair of humans, Expanded Polystyrene Spheres (EPS), and rice husk fly ash to a final product Fiber-reinforced concrete panel. Concrete fracture, catastrophic failure, spalling of concrete and non-quake resistance, with the application of a load are major problems of the current scenario in the concrete world (Mindess, 2009). This paper tries to solve this type of problem by using the natural fibers and some additives which are under patient right. The researcher of this paper has developed a prefab panel which may be the substitute product of brick, ACC block, interlocking block, EPS panel, and local prefab panel. The utilization of industrial waste to usable products for construction is a major challenge that the researcher has taken. The paper shows that product can be made economical and able to reduce environmental challenges. Ingredients like human hair, EPS, chemical agent, cement, fly ash, water, and fiberboard are utilized in a certain time and fixed condition to complete the formation of the Fiber-reinforced concrete panel. The panel was found to have multi-function like a light in weight, fireproof, and flexibility which was its main USP (Unique Selling Point). The researcher thinks this product might change the perception of Nepalese customer, who thinks prefab as a costly and less strength product. Nepal political instability and dependent culture on foreign country shows an impossible possibility to use an artificial fiber and imported fly ash (ITC, 2017). This paper also presents the Nepalese market perception through the business model canvas, a business strategy that can be taken, hindrance, and the possibility to use human hair fiber, fly ash and recycled EPS to complete finished goods.

A study on incorporation of supplementary cementitious materials for sustainable development

In concrete world cement is the main ingredient. The manufacture of cement leads many issues in the environmental safety. So we are in need of replacement against cement as a binder in concrete. There are many alternatives availability for the replacement of cement. Here in our study we use eggshell powder, rice husk ash and sawdust ash as partial replacement of OPC. The mix designated for the study is M25 grade. The replaced eggshell powder & rice husk ash each as 10, 20 and 30 percentage respectively with the weight of cement. Sawdust added as a admixture to improve the properties of concrete. The saw dust added upto 2.5% of binder as additive. The investigation of compressive strength, flexural strength and split tensile strength results at 7 & 28 days were obtained. The research found, the use of eggshell, rice husk ash and sawdust ash improves the structural properties of concrete compared to the conventional concrete.

The cognitive process of students in understanding the triangles in Geometry of Riemann through local content

Learning geometry is one that students fear. They have difficulty understanding the concepts of geometry. Students experience problems with Lobachevsky’s axiom alignment, as well as Riemann’s axiom alignment. Therefore, we need learning that makes it easy for students to imagine these axioms more concrete, although geometry cannot always be carried in a concrete world. The purpose of this study is to describe students’ cognitive processes in understanding the properties of triangles in Riemann Geometry through local content. This is a part of development research. We conducted a needs analysis of the ability of students to understand new concepts in geometry. The subject of this research was chosen from students of mathematics education at one of the tertiary institutions in Bengkulu City, Indonesia. Subjects were interviewed in-depth through task-based interviews. His job is to solve the problem of the properties of triangles in Riemann Geometry. Interview data were analyzed through genetic decomposition analysis. The results of this study were subjects able to analyze the interrelationship between concepts, axioms, and basic properties of geometry through orange peel media. He can attribute and organize. The attributes are obtained from three segments that meet at the ends. Subjects can organize the elements of the triangle so that the nature of a large number of angles in the triangle is more than 180. The conclusions of this study are the subjects can achieve the cognitive process of analysis, and can arrange the correct population.

Deriving Actuality from Possibility

Many believe that the world exists without a cause or reason. Most of them reject an explanation for the whole concrete world because they accept the traditional idea that concrete existence comes only from things that concretely exist. But I provide reasons for thinking that the world might be actual as a result of a feature that is not concrete but abstract. I begin by outlining ideas that some followers of the Platonic Theory of Forms have developed about whether actuality of something can be explained by its possibility. Next, I show that many who think they reject all paths for explaining actuality by abstract facts about possibilities in fact follow such paths. The question of why there exists anything concrete might be answered not by saying that the world exists reasonlessly, but by following some such paths: Having a certain nature for something concrete can turn its possibility into its actuality. Still, we might in the end be forced to accept that the world exists without any reason.

PERAN AKAL DALAM MEMAHAMI PENGETAHUAN LADUNI (TELAAH KITAB RISALAH AL-LADUNIYYAH AL GHAZALI)

This research is a qualitative research. The aim is finding out the role of reason in understanding laduni knowledge. In this case laduni knowledge is the same as intuition. The relationship of reason and intuition which is essentially always in an interactive condition, first seeing the types of knowledge that can be captured by humans. According to al-Ghazali there are four kinds of levels of existence (being). First. The metaphysical form, according to him, is summarized in the Mahfudh letter. Second, empirical forms in the concrete world (alam syahadah). Third, imaginary (imaginative), and fourth, rational form (al-ma’qulat). The relationship of reason and intuition, al-Ghazali made a parable of people who gained knowledge with reason likened to a child and those who obtained knowledge with intuition were likened to (al-mumayyiz). The parable above implies the existence of a level between the two and does not mean there is a separation between each. If this is related to the theory of the human ratio (al- nafs al-natiqoh) after being able to capture a priori or dharuriyyat knowledge, in turn it shows two abilities, namely, the ability to produce knowledge through understanding (through) feeling . The first is creative-methodical-systematic, while the second is creative-non-systematic-systematic. Thus, it is clear that the nature of both knowledge comes from the same source as the derivative of the soul and therefore both are contained in human intellectuality.

Entangled with Traffic Signs: An Ethnographic Account of Internationals Driving in Mainland China

This study investigates the difficulty of internationals’ driving in non-English Chinese environment by reporting on their encounters and reflections in the traffic contexts. The study adopts a geosemiotic perspective and utilizes an ethnography to study foreigners’ usage of traffic signage in Guangzhou, a major and hub city of Mainland China. It collects the verbal and written data of non-Chinese drivers and Chinese traffic authorities as well as scrutinizing some government standards and news reports on this issue. The study finds that foreign sign users are enculturated to an indigenous Chinese driving practice by assimilating into the local “Chinese-only” driving environment. The empirical findings suggest that traffic signs as one form of discourses in place are keyed to culture contextedness for their comprehension and usage by their users as another form of discourses in action. It is therefore argued that although China with its high-end signing system has stepped into a globalized world, the signing system may be less convenient for foreign drivers to mobilize. The contribution of this research rests with two respects: first, it may appeal to more geosemiotic review of signs in the concrete world; second, this study may be helpful in its attempts to make transportation engineers, urban planners, and law enforcers recognize the importance of Romanized versions of traffic signs addressing foreign drivers in Mainland China.

Effects of the nanosilica addition on cement concrete: A review

Nanotechnology has given a new dimension to the concrete world. Among the nanomaterials used as partial replacement of cement, nanosilica (NS) has been used immensely. This review paper summarizes the preparation of nanosilica useable for concrete production, effects of nanosilica addition on cement concrete in terms of varied components, fresh state as well as hardened state and physical properties like workability, setting times, etc. The nanosilica addition hinders workability as the surface area occupied by the nanosilica is quite large. The setting time reduces to a great extent. It gives an in-depth review of nanosilica added concrete prepared using various other additives. The mechanical properties like compressive strength, split tensile strength, flexural strength, and elasticity modulus are discussed in details. Also, the durability aspects of the nanosilica added concrete, the microstructural characterization, and the reduction of structural micropores are discussed in detail. The addition of nanosilica increases the strength properties as well as the durability but reduces the structural micropores. Further, the present scenario and the recommendation for future works of nanosilica application on cement concrete are presented. The use of nanosilica can reduce the consumption of cement, which releases CO2, responsible for global warming. All these aspects make nanosilica added concrete an essential and sustainable material for construction purposes.

Religion and Spirituality: Mental Health Arbitrage in the Body of Mosques Architecture.

Spirituality is a lost human concept and meaning in the universe that is independent of time and place. It is an inclusive concept, which affects everyone. It has also a kind of overlap with the religion; however, unlike the spirituality, religion has potentially a type of certainty and boundaries, and specifically, some adopt it. This meaning implies realities or mental in the objective and concrete world or mental facts in the psyche. The term spirituality and its derivatives, although not being used in the original Islamic texts, is widespread in Muslims literature, both in Persian and in Arabic languages. The past architect being aware of this reality and relying on his beliefs has created a architecture proportionate to his time's culture and beliefs and using architectural elements and has filled the objective body with the spiritual beliefs. The research shows that the religious beliefs and spiritual practices prevent the spiritual and physical, as well as mental, illnesses and, at the same time, reduce the recurrence of the diseases and their symptoms. On the other hand, it accelerates the recovery rate and increases the probability of returning to the initial state.

Mapping Abstract Futures

The future we need to explore is more abstract than it is concrete. As designers, we are constantly conjuring ideas based on a concrete world to improve what we have already seen. Within these predetermined frameworks, we unintentionally bring our own biases to planning the future based on what we know and what we consider safe. However, methods of gathering evidence must reveal the essential dynamics and tensions of the individual in the context of society. The cultural system that represents this process of adaptation can be plotted as a system of language that reflects the dynamics between the concrete and abstract worlds. A craving for such emotional intelligence requires that we expand our binary world into an abstract space for which only the human brain has the capacity. We need such a systematic view in order to think intuitively on multiple levels at the same time.

Mathematical surrealism as an alternative to easy-road fictionalism

Easy-road mathematical fictionalists grant for the sake of argument that quantification over mathematical entities is indispensable to some of our best scientific theories and explanations. Even so they maintain we can accept those theories and explanations, without believing their mathematical components, provided we believe the concrete world is intrinsically as it needs to be for those components to be true. Those I refer to as “mathematical surrealists” by contrast appeal to facts about the intrinsic character of the concrete world, not to explain why our best mathematically imbued scientific theories and explanations are acceptable in spite of having false components, but in order to replace those theories and explanations with parasitic, nominalistically acceptable alternatives. I argue that easy-road fictionalism is viable only if mathematical surrealism is and that the latter constitutes a superior nominalist strategy. Two advantages of mathematical surrealism are that it neither begs the question concerning the explanatory role of mathematics in science nor requires rejecting the cogency of inference to the best explanation.

O sentido como um vir a ser

Neste artigo, pretendemos apresentar as principais bases da proposição da teoria dialógica de uma concepção de sentido como vir a ser, postulado, e ainda por se realizar em interações específicas, em vez de já dado e realizado no texto. O foco é que a linguagem serve às necessidades interacionais dos sujeitos, que são atendidas em situações concretas de enunciação. Isso envolve falar das relações entre linguagem e mundo concreto de acordo com as propostas da Análise Dialógica do Discurso (ADD), para o que é necessário abordar de que maneira a concepção dialógica pensa a apreensão do mundo pelo sujeito, a ideia da constituição do sujeito pela linguagem via enunciação, as relações entre linguagem e realidade, criadas mediante o discurso, e as condições sociais e históricas de enunciação, o que se vincula com a concepção especialíssima de ideologia da ADD. Recorremos para isso, especialmente, a duas obras basilares de autores da ADD.

Pansacramentalism, Interreligious Theology, and Lived Religion

Opening with a philosophical definition of sacrament(ality) as a mediator (mediation) of the sacred in the concrete world, this article offers pansacramentalism as a promising worldview—especially for those rooted in or emerging from the Christian traditions (since, for them, the language of sacramentality may have a stronger resonance)—for bringing together interreligious theology and data mined by Lived Religion approaches to the study of religion. After articulating the concept of pansacramentalism and emphasizing interreligious theology as an emerging model for doing theology, growing trends and changing sensibilities among young people’s religious and spiritual lives (e.g., the “Nones”) is considered insofar as such trends remain relevant for making contemporary theology accessible to the next generation. The article then considers the intersection of pansacramentalism and interreligious theology, especially the issue of determining sacramental authenticity. To explain how this challenge might be met, Abraham Heschel’s theology of theomorphism is offered as but one example as a nuanced means for determining sacramental authenticity of the sacred in the world. Turning to “Lived Religion” approaches, rationale is offered for why pansacramentalism and interreligious theology ought to be taken seriously in the contemporary world, especially considering recent data about the nature of contemporary religious identities among young people living in the West.

Coupling the normative regulation with the constitutive state management in Situated Artificial Institutions

Abstract Artificial Institutions are systems where the regulation defined through norms is based on an interpretation of the concrete world where the agents are situated and interact. Such interpretation can be defined through constitutive rules. The literature proposes independent approaches for the definition and management of both norms and constitutive rules. However, they are usually either not coupled or coupled in an ad hoc and limiting solution. This paper investigates how to make such a coupling. The main contribution of this paper is a formal model basing the regulation provided by the norms on the institutional interpretation of the world provided by constitutive rules. This contribution is based on the Situated Artificial Institutions model that proposes an integrated model of constitutive rules based on status functions.

Process Perspectivism and Linguistic Relativity

AbstractA thorough appreciation of the Whiteheadian subjectivist principle necessitates both a doctrine of panexperientialism as well as a metaphysical perspectivism. Employing a dialectical analysis of these two, this article argues that reality—as understood by the Whiteheadian term “actual world”—is largely misunderstood. Far from representing a singular concrete world, reality is multiplicitous and subject-dependent. As a result of this and the core tenet of process metaphysics—that all existents can be understood as event—it is argued that human language, as its own species of event, interacts with reality in the same way all other events do, and as such must be considered genuinely ontologically creative.

Study on Strength Characteristics of Pervious Concrete Using Mineral Admixtures

Pervious concrete is a special type of concrete emerged out in the concrete world. It is referred as porous concrete or no fines concrete. The porous concrete has wide applications in the pavement with low traffic intensity, sidewalks, pathways, platforms, parking lots etc. Since the pervious concrete allows the groundwater replenishment and prevents the pool of water standing on the earth surface during rainfall-runoff, it helps in the stormwater management. In the present work, the partial replacement of cement with silica fume (SF) and metakaolin (MK) as mineral admixtures to an extent from 10 to 30 % by varying water-cement (w/c) ratio from 0.36 to 0.40 was done to study the effect on the performance of pervious concrete. From the results, an optimum w/c ratio was found to be as 0.38 along with 1.5% of the superplasticizer. The experimental results reveal that the compressive strength of pervious concrete containing mineral admixtures was found to be better than the compressive strength of conventional pervious concrete. Among three different percentage of substitutes used, 20% was found to be an optimum value in both the cases. Pervious concrete with SF as admixture exhibited better strength among the two admixtures..

Toward an Environmental Law of Essential Goods

Perhaps if the preservation of nature is to mean anything in the concrete legal and policy world in which we live, it is time to move away from our reliance on fundamentally changing grass-roots conventional moral values as a prerequisite to policy in a bottom-up approach to change. Instead, perhaps we should consider a revolution in the terms of the explicit legal contract between humanity and nature granting new essential status and fundamental legal standing to the natural world; redefining the core values and assumptions applied to policy from the top-down. The author will call this explicit ‘status' contract between humanity and nature the ‘Ecological Contract' and argue that it is only through legitimizing the status of nature in law that we can assure the long-term sustainability of the natural world.

Political Activism and Other Life Forms in Colonial Buganda

Abstract:This article uses recently unearthed private papers and ethnographic fieldwork to explore the intersection of political practice and environmental ideation in colonial Buganda. In the early to mid-1900s, colonial administrators sought to draw Ganda interlocutors into abstract conversations about a natural world that was devoid of political power. Through Witchcraft Ordinances, imperial administrators sought to distance spirits, rocks, trees, snakes, and other life forms from the concrete world of social movement and dissent. But in late colonial Uganda, the trade unionist Erieza Bwete and the influential spirit prophet Kibuuka Kigaanira navigated environmental spaces that were imbued with political significance. Uganda’s economic and national histories, informed by methodologies that privileged philosophical materialism, overlooked how interactions with multispecies animated anticolonial politics and larger debates about authority. To challenge these earlier assumptions, this article shows how colonial literati and a late colonial prophet interacted with a natural world that was deeply political to conceptualize independence and challenge colonial power.
