Rethinking Teaching: Conceptions of Learning Change and Learning Management
Get PDF Promoting excellence in teaching and boosting learners’ performance is and has always been the corner stone of education in general and in the foreign language classroom in particular. This article addresses the issue of the problematic way of teaching and catering for students with individual differences for a better interaction. Consequently, instructors are often confused and the questions of which teaching approach or learning theory to adopt often arises. The aim of this article is to explore how a teacher should teach in a foreign language classroom. Should a teacher adopt a learner-centered approach or a teacher-centered one? This paper also provides brief guidance to teachers on how to manage learners’ learning styles in the English language classroom for better instructional practices
The Quantum Electro Dynamics Formulization; the Atom; its Architecture and Related Quantum Phenomenons
Get PDFQuanta in a quantum means a point in a smallest Possible space. the other related pieces are that where is this space and how is it defined. wether it is possible to get values out of calculations out of dividing 0 or a point. rooting twice and triple time in following calculations means its quantizing down to its root. and yet keeping the construct of logic that is semi Pythagorean. the base of it all is a tetrahedron and at the end of it all what is defined is a tetrahedron. its a calculation rather than a theory. the theory emerges from the calculation. nobody ever deigned energy. there are types of calculations to measure energy. but like force it is a phenomenon. but to calculate the base of quanta we need a base. and the base is energy. is it is important define what energy is. other wise there is no possibility of calculating what quanta or quantum is. this defines all the particles found by CERN. the Source of the values are converted into this theories base measurement scale index. or MEV. the GEV converses is avoided and used as a square of MEV. but except for Higgs which is not understood and self theorized like everything else. It is unto you to accept the definition and validity since the values are quite closely matched. it is not the intention of writing this paper to explain an experimenting and how it matches the mathematics. It is mathematics. But written in english. it is written in C#. Again for easier comprehension. as greek letters are often confused by the power of the Gods. As in Hydra or something. That has been taken care of. A point to note are the catalyst agents used from the form of energy conversions. To Force charge and Mass. you would find that the whole theory started off from nothing or everything empty and in a shell of existence that I have defined to be energy. And everything else that has been calculated are geometric or pythagorean. Not in the sense of triangles but to the point of architecture.
That everything that is floating must have a propagation path and it converges and diverges to inwards and outwards. A more clarified intention of mathematics will be comprehended upon looking at the equations. A problem to be faced was the scale match with the cern mega electron volt and the classical kgs and newtons. However that has been solved by quantizing the speed of light and using the mass number and energy to be the mega electron volt. As you would see that it makes sense that if a light is moving at a speed of km to 100000 it is also possible to have the same speed if its moving .1000000 in x_plank scale or ppx
The Practice and Prospects of Active Learning Methods in Wollo University
Get PDFThis study was mainly designed to assess the practice of active learning in university classrooms. For this purpose instructors from the two campuses of Wollo University were conveniently selected. Data was collected using open and close ended questionnaires, interviews and observation. A total of 70 instructors filled the questionnaire. The type of research employed for this study was descriptive survey research. The collected data were organized, analyzed and interpreted both quantitatively (using percentages and mean values) and qualitatively (using narrations and descriptions). Finally, the results revealed that the instructors did practice active learning but in a low scale. Lecture methods, discussion, cooperative learning, and question-answer methods are mostly used active learning methods. There were various hampering factors affecting the overall practice of active learning strategies including shortage of time, large class size student’s lack of interest for active learning method and shortage of teaching materials. .Based on the findings, reconsidering the modular modality system and revising the training forms for instructors are recommended
Title: Primary Dysmenorrhea: Associated Symptoms, Impact and Management among Females in the Menoua Division of the West Region of Cameroon. Cross-sectional Study Running Title: Primary Dysmenorrhea in the Menoua Division
Get PDFPrimary dysmenorrhea, or painful menstruation in the absence of pelvic pathology is a common and often debilitating gynecological condition that affects between 45% and 95% of women at reproductive age.
The current study aimed to assess the prevalence of dysmenorrhea and associated menstrual symptoms and their self-management techniques among females. This cross-sectional study was conducted in the Menoua Division, which has six subdivisions namely: Fokoue, Dschang, NKongni, Penka Michel, Santchou and Fongo tongo .For this purpose, 668 women aged from 12 to 38 years were considered. A self-administered questionnaire was used to collect data. The main results revealed that dysmenorrhea was reported on almost two-thirds of the women (66.17%). In the 442 girls who reported dysmenorrhea Severe pain was reported by 20.71 % of respondents. More than one-third of the respondents (39.75%) reported using pain relief medications with 23.38 % of herbal medicine and 76.54 % of synthetic medicines. The gastrointestinal problems (diarrhoea and vomiting were the most common symptoms experienced. Less than 19.41% of respondents reported having consulted a doctor for their dysmenorrhea, while most of them consulted friends and family.Dysmenorrhea is a very common problem among university students. A number of symptoms were related to dysmenorrhea. Even though it is common, and may not have a pathological cause, few women seek medical advice. Increasing the awareness might help in relieving the burden of this common health problem
Water Security in the Mekong River Basin Challenges, Causes and Solutions
Get PDFWater, an essential element in sustaining life is of special importance to society and economic development. Although renewable, water resources are not infinite. It can be said that equitable and sustainable water resource management in the context of climate change is a challenge that all Mekong countries have been facing. The challenge becomes bigger in the context of water scarcity when the total amount of water is sharply decreasing and the water quality is declining, failing to meet domestic and industrial needs. Based on a study into the current situation of water security in the Mekong River, the author points out the basic challenges that threaten water security in the river basin. At the same time, the author discusses the reasons leading to this situation. Based on the research on the current situation of challenges and underlying causes, the author proposes a number of necessary solutions to cope with current and upcoming challenges. These solutions, including legal, diplomatic, economic and political solutions, should be implemented in a synchronized and long-term manner in the future

Rift Volcanism and Rift Basin in Central Myanmar Basin
Get PDFThe Central Myanmar Basin is made up of Tertiary sedimentary rocks between the Rakhine Western Ranges in the west and Shan Plateau to the east. The basin consists of six sub-basins: Putao, Hukawng, Chindwin, Salin, Pyay and Ayeyawady Delta basin. This 1000 km× 200km tectonic strip in NNW-direction in Central Myanmar Basin is characterized by the presence of numerous ENE to northeast and east-west trending normal faults and north-south to NW-SE and NNW-SSE trending folds and thrusts. This arrangement of structures is indicative of an extensional stress in NNW-SSE direction and a compressional stress in ENE-WSW direction. Tensor solution of earthquakes which occurred in Central Myanmar Basin also indicates a dominant extensional stress direction oriented NNW-SSE. This NNW-SSE extensional direction appears to have favored the formation of rifts in ENE-WSW, NE-SW and E-W direction which were later emplaced with volcanic rocks. These volcanic rocks were derived from mantle material which risen into the several segments of rifts from underneath of the crust during rifting. Majority of these volcanic rocks are different types of basalt, andesite, dolerite, volcanic tuff, volcanic ash, lava flow and rhyolites. The studies of associated sedimentary rocks with the volcanic rocks indicate that extension and volcanic activity began in the north in Early Tertiary and migrated to the south from the Miocene to Quaternary. The Central Myanmar Basin and Central Andaman Basin record an active extensional process that varies laterally from continental rifting in the north in Central Myanmar Basin and sea-floor spreading in the south in Central Andaman Basin. The objective of this paper is to define regional volcanic differentiation pattern and their linear emplacement which are in accordance with regional tectonic stress field and to interpret them in term of tectonic deformation. Bimodal basalt-rhyolite suite with the presence of intermediate composition and compositional variations of volcanic rocks indicate that the volcanic rocks are formed by assimilation, fractional crystallization and the crustal components and magma mixing. Geochemical analyses of these volcanic rocks reveal that they are also enriched in the alkalis, high level of barium and strontium and light rare earth elements.
Associated host rocks of the volcanic material are sedimentary rocks of the Peguan Group (Oligocene-Miocene) and Irrawaddian Group (Pliocene-Pleistocene)
Enhanced Parallel Hash Function Algorithm Based on 3C Construction (EPHFA-3C)
Get PDFThe hash function is a function that can convert data from variable size to fixed-size data that can be used in security of communication like, authentication, digital signature and integration. In this paper, a parallel, secure and fast hash function algorithm that is based on 3C construction is proposed. It is an enhancement for the MD construction. This enhancement makes the construction more resistant to the extension and multi-blocks attacks. The parallel structure of the algorithm improves the speed of hashing and reduces the number of operations. The simulation analysis such as hashes distribution, confusion and diffusion properties, and collision resistance are executed. Based on the results, our proposed hash algorithm is efficient, simple, and has strong security compared with some recent hash algorithms
Kinetin and Nitrogen in Agronomic Characteristics of Soybean
Get PDFThe objective of this work was to evaluate the application of kinetin associated with nitrogen in coverage on the agronomic characteristics and soybean yield. In the 2016/2017 harvest, a 6x2 factorial scheme was used, six doses of kinetin (0; 0.30; 0.60; 0.90; 1.20; 1.50 g ha?1) and two doses of N (20 and 40 kg ha?1) and in the 2017/2018 harvest, factorial scheme 5x2 was used, five doses of kinetin (0; 0.25; 0.75; 1.00; 1.25 g ha?1) and two doses of N (20 and 40 kg ha?1). Agronomic plant height characteristics, first pod insertion height, number of grains per plant, number of pods per plant, number of grains per pod, number of grains per pod, hundred-grain mass and grain yield were evaluated. The use of N alone and associated with kinetin increased the number of pods and grains in the 2016/2017 harvest. In the 2017/2018 crop, kinetin caused a reduction of 8.9% at plant height and N caused an increase in plant height and first pod insertion and reduced the number of pods and grains per plant, grains per pods and productivity
