Published: November 2019

One aspect of cognitive development that can be developed by children is by the introduction of color in early childhood, for it is necessary to do learning through learning methods that can improve the development of color recognition capabilities. Because cognitive development must be mastered by children to recognize colors related to sharpening the ability of imagination, develop intelligence and mindset in children. One method that can be done to introduce color is through an experimental method to determine the ability of children to explain the process of something that has been tried, provide a learning experience for students about the process of something happening, and bring a high enthusiasm to children. This study used a quasi-experimental method with nonequivalent control group design research design using two classes consisting of A1 experimental class and A2 control class at Al-Falah Kindergarten. Based on the results of the study, it was found that the average gain of the experimental class was 22.30 while the average gain value of the control class was 1.69, which means that the effect of color recognition on the experimental class children after treatment was increased compared to the untreated control class. Therefore, this research is recommended for early childhood educators that the experimental method can influence color recognition for early childhood.Salah satu aspek perkembangan kognitif yang dapat dikembangkan oleh anak yaitu dengan pengenalan warna pada anak usia dini, untuk itu perlu dilakukannya suatu pembelajaran melalui metode pembelajaran yang dapat meningkatkan perkembangan kemampuan pengenalan warna. Karena perkembangan kognitif harus dikuasai anak untuk mengenali warna yang berkaitan dengan pengasahan kemampuan imajinasi, mengembangkan kecerdasan dan pola pikir pada anak. Salah satu metode yang dapat dilakukan untuk memperkenalkan warna adalah melalui metode eksperimen untuk mengetahui kemampuan anak menjelaskan tentang proses terjadinya sesuatu yang telah dicoba, memberikan pengalaman belajar terhadap anak didik tentang proses terjadinya sesuatu, dan memunculkan semangat yang tinggi kepada anak. Penelitian ini menggunakan metode kuasi eksperimen dengan desain penelitian nonequivalent control group desain dengan menggunakan dua kelas yang terdiri dari A1 kelas eksperimen dan A2 kelas kontrol di TK Al-Falah. Berdasarkan hasil penelitian diperoleh bahwa rata-rata nilai gain kelas eksperimen 22,30 sedangkan rata-rata nilai gain kelas kontrol yaitu 1,69 yang artinya pengaruh pengenalan warna terhadap anak kelas eksperimen setelah diberi treatment lebih meningkat dibanding kelas kontrol yang tidak diberi treatment. Maka dari itu, penelitian ini direkomendasikan kepada pendidik anak usia dini bahwa metode eksperimen dapat mempengaruhi pengenalan warna terhadap anak usia dini.

The population in this study were students of SMP 1 Jatisari class VIII A in Sukamaju Village which consisted of 18 students and 12 female students. This study was a quasi-experimental study using the results of a trial test pretest-posttest experimental control group. The instrument used in this study is a test to measure mathematical creative thinking skills in the form of 5 questions. Then the score data of students' mathematical creative thinking ability were analyzed statistically by using a difference test of two average values from the results of the pretest-posttest. The results showed that students' creative mathematical thinking ability using the Problem Based Learning approach was different from the results of the pretest-posttest. Besides that students also showed positive perceptions of problem-based learning and there were good results on mathematical creative thinking skills.

This investigate is motivated by the low ability to comprehend the mathematical concepts of SMP students in KBB, so a learning approach is needed to decipher these problems. Alternative approaches are applied, namely the contextual approach. The method make use of in this investigate is an experimental method with a control group design pretest posttest. The population in this research were all junior high schools in KBB while the school sample was Kahuripan Lembang Middle School which was chosen based on school randomization. Sample class were taken randomly from the 4 classes of class 7 of Kahuripan Lembang Middle School, class 7-2 as the tentative class and class 7-4 as the control class. The tentative class uses contextual learning while the ordinary learning control class. The reason for taking class VII is because with deliberation in the semester one there are topics in the Triangle and Quadrangle that will be used in the study. The instrument in this investigation was a package of five test questions. The researcher can conclude that the achievement and repair of the capability of understanding The mathematical concept of SMP students who use a contextual approach is better than those using ordinary learning.

The skill to think critically and mathematics is the basic essential mathematic skills and need to owned by students who study math. This research method use qualitative descriptive research which aims to analyze the student’s mistakes when they do mathematic critical thinking questions on the discussion of circle and flat side geometry. This research subject is 8th grade student who study at one of public junior high school in the city of Purwakarta, Indonesia. The test instrument was 5 essay questions. The research result show that more students have their own difficulties when they do question number 2,3 and 5.  I suggested the learning strategy which can upgrade their mathematics critical thinking skill should be used as the learning process.
Funk Staden: Atualidade do gesto antropofágico
Authors: Cohn Greice , Leandro Anita
Published: November 2019

Em 2012, quando o Centro Municipal de Artes Hélio Oiticica, no Rio de Janeiro, abrigava a exposição Até que a rua nos separe, dos artistas Dias & Riedweg, um grupo de estudantes do ensino médio visitou o evento. Entre as instalações da exposição, Funk Staden (2007) chamou particularmente a atenção dos alunos pela forma como ela atualizava o tema ancestral da antropofagia, inscrito, desta vez, de maneira ao mesmo tempo lúdica, sensual e violenta, na cultura funk das favelas cariocas. Analisaremos aqui essa obra participativa, com grande potencial pedagógico, e sua reverberação nos trabalhos autorais dos alunos, produzidos a partir desse encontro.
Camerar um ponto de ver: a pedagogia das imagens em Boa Água
Authors: Pipano Isaac , Migliorin Cezar
Published: November 2019

A relação entre o cinema e educação tem sido historicamente fundamentada no âmbito da representação, instaurando um duplo regime entre a produção das imagens e a produção do saber. Tal perspectiva persiste situando as imagens a partir da centralidade humana que organiza as dicotomias tão caras à epistemologia ocidental moderna cujo peso segue atuando nos quadros teóricos e conceituais que balizam sujeito x objeto, verdade x mentira, eu x outro, superfície x profundidade. Mais do que tecer apenas uma crítica à representação como tendência ao universal, caberá indagar-nos sobre quais as consequências éticas, estéticas e políticas para a realização do cinema nas escolas diante do seu desfundamento. Para tanto, nos deteremos no curta-metragem Boa Água, realizado num projeto de formação na cidade de Conde, na Paraíba.
Guevara And Kerouac Hit The Rhizome: Displacement In Walter Salles's The Motorcycle Diaries And On The Road
Authors: Maya Neto Olegario da Costa
Published: November 2019

Going beyond binary formulations such as liberty versus norms, mobility against stability, or movement and stasis, I analyze Walter Salles's movies The Motorcycle Diaries (THE MOTORCYCLE, 2004) and On the Road (ON THE ROAD, 2012) in terms of Clifford's (1999) discussion of displacement and of Deleuze and Guattari's rhizome (2005). Displacement in The Motorcycle Diaries (THE MOTORCYCLE, 2004) arises from the de-centering of the expected homogeneous continent since, instead of finding the indigenous heart of the continent where natives live off their lands undisturbed, and where one single cultural and linguistic unspoiled essence can be found, the protagonists encounter a multitude of biomes, languages, cultures and peoples. In comparison, displacement On the Road (ON THE ROAD, 2012) can be found in the circularity of motion created by a series of travels with apparent no beginning or end, and in the act of travelling itself since it enables eruptions of creativity in the characters as potency of becoming.
O desejo de ilusão e o teatro da memória em Cartas a Lumière (2017)
Authors: D Artemare Antoine , Urano Pedro
Published: November 2019

Nesse artigo, partiremos da análise da obra Cartas a Lumière (2017) para mostrar de que forma o filme – através de um dispositivo de realidade virtual imersivo que inclui o corpo do espectador de maneira imediata e interativa – não apenas produz uma nova experiência perceptiva e sensível mas também desloca as noções clássicas de ponto de vista, enquadramento e instância narrativa, apresentando novos caminhos estéticos para o cinema contemporâneo. Buscaremos, no entanto, relativizar o discurso contemporâneo que associa a essa técnica um caráter revolucionário. Para isso, demonstraremos o quanto o dispositivo de realidade virtual se inscreve em uma história mais ampla de dispositivos imersivos e de ilusão que tendem a reduzir a distância crítica entre o espectador e a imagem, dialogando desse modo com dispositivos do passado. Assim, buscaremos oferecer uma compreensão histórica da imersão e da ilusão que nos ajudaria a entender melhor as novas tecnologias contemporâneas. Finalmente, refletiremos sobre possíveis problemas éticos que esse dispositivo, que aprimora de maneira considerável a estética da transparência, pode desencadear em relação ao espectador.

Accessibility of TV media for the dual-sensory impaired in Finland and in the UK
Authors: Ojala Stina , Palmer Russ , Lahtinen Riitta
Published: November 2019

One of the most used media is television. Almost all of us have a television set at home. Television is commonly thought also to be accessible, and for most of us, it seems to be so. However, there are people who cannot enjoy televised programmes without special measures. These measures include subtitling, audio description and sign language interpretation. All these are mentioned in the in-force EU Audiovisual Media Services Directive.

In this article we look at how these are broadcast in different countries, what equipment is needed for receiving them, and how accessible the programme information (EPG) and menus to choose these accessibility options are, as they most often are not automatic, but have to be turned on in the accessibility options menu or the TV set or digital terrestrial receiver box (digibox). This article focuses on accessibility with special interest on the dual-sensory impaired perspective over four days comparing two countries: the UK where all three accessibility features mentioned above are well-established and Finland, where accessibility features concentrate mainly on subtitling.

Decrypting the Central Mystery of Quantum Mathematics:
Authors: Boyd Jeffrey
Published: November 2019

We live in a world, half of which consists of invisible elementary waves, of which we know very little. They are not electromagnetic waves: they travel in the opposite direction and convey no energy. What is the medium in which they travel? Franco Selleri (1936-2013) of University of Bari, Italy, devoted his career to answering that question. He developed his own theory of relativity. Zero energy quantum waves travel in Lorentz aether at rest. His relativity differs from Einstein’s Theory of Special Relativity (TSR) in terms of Absolute Simultaneity. If two events are simultaneous for one observer, they are simultaneous for all observers. Although this contradicts TSR, international treaties have adopted Absolute Simultaneity as the basis for coordinating all atomic clocks to the nanosecond. Atomic clocks control all other clocks. Absolute simultaneity is essential for commerce and computer networks.. Selleri’s relativity can be divided into two parts: time and aether. Time can be understood without ever speaking of the speed of light. When it comes to aether, a subject rarely mentioned today, it appears to be Isaac Newton’s absolute time and space, modified to fit the Lorentz transformations and the non-Euclidean curved space of Einstein’s General Relativity.
