Penelitian ini bertujuan untuk mengkaji dan mendapatkan gambaran mengenai penggunaan pendekatan Contextual Teaching And Learning (CTL) melalui strategi bertanya yang berbasis masalah-masalah sosial di lingkungan siswa di kelas X Tata Busana SMKN 4 Rambah. Metode dalam penelitian yang digunakan adalah metode Penelitian Tindakan Kelas/ PTK (classroom research). Hasil penelitian ini dengan Contextual Teaching And Learning (CTL) dalam pembelajaran sejarah melalui strategi bertanya yang berbasis masalah-masalah sosial di lingkungan siswa di kelas X Tata Busana SMKN 4 Rambah terbagi atas empat langkah: langkah pertama, sebelum melakukan tindakan peneliti berusaha mengenali dahulu karakter kelas. Karena setelah mengenali karakter kelas akan mempermudah proses pembelajaran. Karakter kelas X Tata Busana bisa disebut cukup aktif. Siswa aktif menjawab pertanyaan dari guru mengenai fakta sejarah. Dengan mengembangkan CTL melalui strategi bertanya yang berbasis masalah-masalah sosial di lingkungan siswa, siswa mempunyai pemahaman dan kepekaan terhadap masalah yang ada di sekelilingnya selain memahami materi sejarah yang berupa fakta dan uraian peristiwa. Langkah kedua, pada awal pembelajaran guru harus terlebih dahulu mengarahkan dan menjelaskan kepada siswa bahwa dengan belajar sejarah yang dihubungkan dengan kekinian dapat memberikan manfaat dan makna bagi kehidupan sehari-hari. Hal tersebut dilakukan agar siswa tidak bingung dengan penerapan CTL yang diaplikasikan oleh guru. Selain itu, untuk meningkatkan keaktifan siswa guru harus memotivasi siswa untuk belajar aktif selama proses pembelajaran berlangsung.

Penelitian ini dilakukan untuk memperoleh deskripsi tentang proses peningkatan keterampilan menulis teks pantun berbantuan pemetaan pikiran siswa kelas III di SDN 006 Rambah Rokan Hulu. Metode penelitian yang digunakan adalah penelitian tindakan kelas yang dilakukan dalam dua siklus. Setiap siklus terdiri atas empat tahapan penelitian, yaitu perencanaan, pelaksanaan, pengamatan, dan refleksi. Data penelitian ini adalah hasil observasi tentang tindakan guru dan siswa dalam pembelajaran, catatan lapangan dan hasil belajar siswa. Data hasil observasi aktivitas guru dan catatan lapangan dianalisis secara kualitatif. Data hasil belajar menulis teks pantun dan hasil observasi aktivitas siswa dianalisis secara kuantitatif.
Hasil penelitian menunjukkan bahwa pemetaan pikiran yang digunakan sebagai alat bantu dalam pembelajaran dapat meningkatkan aktivitas dan hasil belajar siswa dalam menulis teks pantun. Proses pembelajaran dengan bantuan pemetaan pikiran membantu siswa menghasilkan gagasan pokok dan gagasan penjelas, dan menghubungkan gagasan-gagasan tersebut dalam kalimat-kalimat yang padu dan runtut. Dengan demikian, pembelajaran menulis teks pantun berbantuan pemetaan pikiran menjadikan siswa berpikir kritis, logis, dan sistematis. Sementara itu, faktor yang menghambat pembelajaran menulis teks pantun dengan bantuan pemetaan pikiran adalah pengelolaan kelas yang belum maksimal serta kurangnya penguasaan kosa kata siswa.

Modeling the Quasiperiodic Radial Velocity Variations of γ Draconis
Authors: Delgado Victor Ramirez , Dodson-Robinson Sarah 
Published: September 2020

Abstract

γ Draconis, a K5III star, showed radial velocity (RV) variations consistent with a 10.7 Jupiter mass planet from 2003 to 2011. After 2011, the periodic signal decayed, then reappeared with a phase shift. Hatzes et al. suggested that γ Dra’s RV variations could come from oscillatory convective modes, but did not fit a mathematical model. Here we assess whether a quasi-periodic Gaussian process—appropriate when spots with finite lifetimes trace underlying periodicity—can explain the RVs. We find that a model with only one quasiperiodic signal is not adequate: we require a second component to fit the data. The best-fit model has quasi-periodic oscillations with P
1 = 705 days and P
2 = 15 days. The 705 day signal may be caused by magnetic activity. The 15 day period requires further investigation.
Santo à La Havane : vagabondages cinématographiques d’un héros mexicain
Authors: Vincenot Emmanuel 
Published: September 2020

L’une des formules génériques les plus durables du cinéma mexicain éclot au milieu des années 1950, alors que l’âge d’or des studios touche à sa fin ; elle met en scène les héros de la lucha libre, ce sport-spectacle qui rassemble alors des millions de fidèles chaque semaine. Après avoir contextualisé l’émergence du cine de luchadores, l’article retrace la trajectoire cinématographique de Santo, la plus grande vedette du genre, et se concentre sur les deux premiers opus de sa filmographie : Santo contra cerebro del mal [Joselito Rodríguez, 1961] et Santo contra hombres infernales [Joselito Rodríguez, 1961]. Ces deux longs métrages tournés à La Havane sont particulièrement représentatifs du cinéma dit de mexploitation et se caractérisent par une désinvolture formelle qui atteint une dimension quasiment expérimentale, mettant à nu les ressorts mêmes du langage cinématographique.
Michèle Blanchard-Lemée (1936-2017) et l’Afrique antique
Authors: Darmon Jean-Pierre 
Published: September 2020

Michèle Blanchard-Lemée (1936-2017), très tôt associée à l’équipe d’Henri Stern au CNRS et aux travaux sur la mosaïque antique ainsi qu’au Recueil général des mosaïques de la Gaule, a néanmoins été également disciple de G. Ch. Picard. Elle a commencé sa carrière scientifique par une étude sur la mosaïque africaine sous l’autorité de G. Ville. Et son intérêt pour l’archéologie africaine ne s’est jamais démenti. Sa thèse sur les pavements de Djemila (Algérie), sous la direction de P.-A. Février, a fait date, et ce site est resté au cœur de ses préoccupations : sa toute récente publication posthume a porté sur la « maison de Bacchus » de Djemila. Ses travaux, ses conseils concernant la restauration et la muséographie des mosaïques antiques d’Algérie, son rôle dans la diffusion des études sur la mosaïque dans ce pays et en faveur de la formation de ses chercheurs, lui confèrent une place notable dans les récents développements de l’archéologie algérienne et de la coopération franco-algérienne dans ce domaine.

Le Concours théâtral interafricain : quelles archives ? quels usages ?
Authors: Gahungu Céline 
Published: September 2020

Créé par l’Office de coopération radiophonique (OCORA) en 1967, le Concours théâtral interafricain, objet radiophonique et compétition dramaturgique, poursuit deux objectifs : surmonter les difficultés d’accès à l’édition et aux structures de représentation ; sur la demande des directeurs des radiodiffusions africaines, initier un programme tout à la fois culturel et attractif. Du tournant des années soixante à 1991, depuis l’OCORA jusqu’à Radio France Internationale (RFI), le Concours théâtral interafricain devient, au gré de ses éditions, une instance destinée à légitimer les dramaturges africains. Fondée sur une recherche en cours, cette chronique s’intéressera à ses archives encore très largement méconnues et étudiées.
La Novation de l’économie politique au Japon. La victoire de Koizumi à l’automne 2005 marquera-t-elle le tournant d’une social-démocratie souterraine à une social-démocratie citoyenne ?
Authors: Nohara Hiroatsu 
Published: September 2020

Ce texte cherche à comprendre la modalité d’articulation entre l’économique et le politique dans un Japon qui est en train de sortir d’un long tunnel de déflation. Pour ce faire, on utilisera comme analyseur, les signes de changements intervenus lors de l’élection parlementaire de l’automne 2005 qui a consacré une victoire écrasante du « nouveau » PLD reconfiguré par l’ex-premier ministre Koizumi. Par delà la « mondialisation » qui impose les mêmes pressions aux différentes économies, le capitalisme japonais fait face à une transition du régime dans laquelle les divers enjeux sociétaux s’expriment à travers des jeux d’acteurs. La question est de savoir si ces jeux permettent à ce pays de passer d’une « social-démocratie souterraine » - mode de gouvernance spécifique au Japon - forgée après la seconde guerre mondiale à une social-démocratie citoyenne.

Whole cottonseed (WCS) is an important source of protein for ruminants, however, it contains a polyphenolic secondary metabolite gossypol which may reduce its palatability and cause pathophysiological effects. The study was aimed at evaluating the effects of feeding graded levels of WCS on the haemato-biochemical parameters of Red Sokoto bucks (RSB). After a 14-day pre-treatment period, 20 bucks (n = 5) were assigned for 90 days to one of four isonitrogeneous treatments: control (A); 0 % (B); 15 % (C); 30 % and (D); 45 %. Blood was collected for Packed Cell Volume (PCV) and serum analyses at days 0, 45 and 90 of the experimental period for concentrations of urea, creatinine, total protein, albumin, globulin and activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP). The PCV was decreased in groups fed above 15 % of WCS on days 45. There were no significant (P > 0.05) differences in globulin concentration, alanine aminotransferase and alkaline phosphatase activities but aspartate transferase activity was higher (p < 0.05) in group D (45% WCS) compared to the various treatment groups. The urea concentration was higher (p < 0.05) in groups B and D at day 45 compared to the control group. The creatinine concentration was higher (p < 0.05) in group D at days 45 and 90 compared to the control group. The serum total protein and albumin concentration were higher (p < 0.05) in groups C and D at day 45 compared to the control group. Our finding revealed that prolonged feeding of bucks above 30 % WCS for more than 60 days exerted considerable deleterious and adverse effects on blood constituents leading to aneamia, hyper-cretenaemia, ureamia, increased levels of total protein, albumin, aspartate transferase activity and death.

Necrotic enteritis and its management in 13-week old commercial pullets in Katsina, Nigeria
Authors: Abubakar A. , Aliyu H.B. , Sa idu L. , Usman S.G. 
Published: September 2020

Necrotic enteritis is rarely reported because it is often misdiagnosed as coccidiosis due to similarity in clinical and pathological features. A field outbreak of necrotic enteritis in a flock of 13 weeks old 4,500 commercial pullets was investigated, the onset of the disease, morbidity and mortality rates were recorded. Post mortem examinations were conducted and gross lesions were documented. Tissues were collected and fixed in 10 % neutral buffered formalin and processed for histopathological examinations. Clinical signs observed were ruffled feathers, weakness, somnolence, loss of weight and diarrhoea; while the gross lesions observed were emaciated carcasses, lean abdominal fat, enlarged, pale and haemorrhagic liver; enlarged, mottled and congested spleen; mucus and diphtheritic membrane on the jejunal mucosa and enlarged kidneys. The histopathological findings of the intestine were diffused necrotic epithelial cells with marked mononuclear cells infiltration in the mucosa with severe oedema fluid. The necrotic enteritis was diagnosed based on clinical signs, pathology as well as isolation and identification of Clostridium perfringes. Triplesulfa® (sulfadimidine sodium, sulfadiazine sodium and sulfamerazine sodium); Tridox® L.A (20% Oxytetracycline long acting) and Enterocillin® (Amoxycillintrihydrate and Colistin sulphate) were ineffective, while copper sulphate at 1g/5L of drinking water was found to be effective for the treatment of the disease. The haematological values indicated lymphocytosis due to damage of the tissue caused by C. perfringes and the toxins produced.

PROJECT-BASED LEARNING AS AN APPROACH TO DEVELOP CRITICAL THINKING SKILLS: A LITERATURE REVIEW
Authors: Junisbayeva Symbat 
Published: September 2020

Project-Based Learning is a learner-centered approach, which is known as one of the ways that facilitates the development of professional competencies and promotes learners’ critical thinking skills. This paper provides a selective review of the literature and the analysis of the studies on Project-Based Learning (PBL) in the field of foreign language education and critical thinking skills including the main concepts, key components and a learning process within PBL. PBL has a strong theoretical support from the foreign literature, and most of the researchers understood and implemented it as an approach to foster critical thinking skills in the reviewed studies; however, not all of them complied with its essential elements proposed as “Gold Standard of PBL”. Particularly, the analysis of the selected studies in PBL sphere revealed that most of the researchers did not take into consideration the requirements of the last and main stage of the PBL as “Public product”, that demands the projects to be presented in front of the alternative audience. Even though the final products were designed within these projects, they were not performed out of the classroom, which in its turn is opposite to the policy of rigorous “Project-Based Learning”. Key words: PBL, critical thinking skills, foreign language education

Published: September 2020

Mathematical education is part of the system of continuing education and is of great importance in ensuring the development of human intellectual abilities in modern society. In the secondary education system, teaching mathematics takes a special place in the development of cognitive abilities and logical thinking of students.The main goal of our study is to develop methodological foundations for teaching word problems in the process of teaching mathematics in secondary school and to test its effectiveness experimentally. There are various methods for solving word problems: arithmetic method, algebraic method, geometric method, logical method, practical method, and tabular method. Different mathematical models are created based on each method. In the course of secondary school mathematics, two methods of solving word problems are considered: arithmetic and algebraic. The main purpose of the conducted pedagogical experiment was to test the effectiveness of the method that allows to increase the level of mathematical training of secondary school students, based on the use of the algebraic method in solving word problems of secondary school students. Prospects for research on the development of teaching methods for solving word problems are associated with a deep consideration of professional, creative and personal aspects of students.Keywords: teaching to solve word problems, word problem, structure of word problem, algebraic method.
Competitive Landscape Shift: When does a competitor matter?
Authors: Kamzabek Takhaui Barkhanuly 
Published: September 2020

This research broadens the Strategic Entrepreneurship construct. This research aims to clarify the relationship between strategic and entrepreneurial activities with competitive landscape changes by questioning is the firm limited to the current boundary of competition? By integrating the competitive dynamics and multimarket competition theory, the study finds the correlative relationship between Strategic Entrepreneurship activities with competitive landscape shifts. The study found that explorative activities do not have any commonalities with traditional competitors. Also, the high involvement competitive tension with rival causes the firm to go beyond its current landscape, which enables the incumbent firm to increase the market commonality with new competitors and traditional competitors. The research also looking for the anomalies that emerged within the process of it and give several explanations for that. By analyzing the M&A history (between 1995 - 2019) of big players in the consumer goods industry which has a similar core (Procter & Gamble and Unilever) I found the support to the hypothesis.Keywords: explorative activities, exploitative activities, competitive tension, competitive landscape
The role of repetition in learning math
Authors: Yessenbolkyzy Akerke Yessenbolkyzy , Yessirkepova Ardak 
Published: September 2020

Mathematics is one of the most important aspects of school education. School mathematics is a meaningful, fascinating and accessible field of activity, giving the student rich food for the mind, connecting him with universal human culture, forming the most important personality traits.In learning mathematics, practice makes perfect. In the process of teaching math, the repetition of the studied material is given an important place. Properly organized repetition is one of the factors contributing to the intellectual development of each student, their achievement of deep and lasting knowledge. The need to repeat the previously studied material is caused by the very structure of the curriculum of mathematics. For example, students go through the curriculum topic: “Quadrangles” in 8th grade, but use it in grades 10-11 when studying the topics: “Surface of bodies of revolution”, “Surface area”, “Volume of bodies”, etc.To teach mathematics without repeating the material previously passed on every lesson every day, this means transmitting, retelling to students a certain amount of different laws, theorems, formulas, etc., completely not caring about how firmly and consciously this material was mastered by our pets; it means not giving children deep and lasting knowledge. Researches showed us that repetition is the main instrument of the study. Results of the analysis revealed that students exposed to repetition with variation approach had significantly higher achievement, conceptual understanding and improved retention.

Esse estudo teve como escopo pesquisar como estão estruturadas e como estão funcionando as políticas municipais de inclusão de alunos com deficiência intelectual na Escola Regular de Ensino Fundamental Inclusiva Hildemar Maia, no municipio de Macapá. O marco temporal escolhido foi a partir da década de 90, momento de debate da educação inclusiva no contexto do documento das Nações Unidas denominado de Declaração de Salamanca. Foram realizadas entrevistas com 05 cinco professoras da Escola regular de ensino fundamental inclusiva Hildemar Maia no município de Macapá, uma (1) coordenadora pedagógica e também foram realizadas observações na sala de aula da professora do ensino fundamental, bem como entrevista com o gestor da Divisão de Educação Especial da Secretaria Municipal de Educação- SEMED. As entrevistas e a observações foram realizadas com base nos conceitos apresentados pela fundamentação teórica por meio da coleta de informações. Os resultados demonstraram que as professoras interagem continuamente uma com a outra verificando a preocupação em compreender a importância de práticas pedagógicas acessíveis para a inclusão qualitativa dos alunos com deficiência intelectual, mas as políticas estabelecidas pela Diretriz Municipal de Educação Especial não se efetivam em sua integralidade, principalmente nas questões relativas à estrutura física e a formação de professores por tipologia das deficiências.
