Common Core Mathematics Standards (CCMS) is a major effort at revamping the U.S. K-12 mathematics education in order to improve American students’ mathematical performance and international competitiveness. To ensure the successful implementation of CCMS, there have been calls for both recruiting from those with the strongest quantitative backgrounds (e.g., STEM majors) and offering rigorous mathematics training in teacher preparation. Missing from the literature are questions of whether STEM majors who arguably represent the strongest candidates for the teaching force have the depth of content understanding in order to teach mathematical topics at the rigorous level that CCMS expects, and whether future mathematics teachers need the opportunities to learn rigorously the K-12 mathematical topics they are expected to teach down the road. Our paper addresses the knowledge gap in these two areas through investigating the understanding of the concept of slope among a group STEM majors who were enrolled in an undergraduate experimental teacher preparation program. We found that even among these students, there are holes in their conceptual understanding of slope and of the connection between linear equation and its graph. These weaknesses could pose challenges for their preparedness to teach the slope concept consistent with the rigor that CCMS calls for. Taking courses that specifically address the K-12 math topics is helpful. We discuss implications of these findings for the content preparation of mathematics teachers.
Investment in tourism and transportation in Nigeria is an investment in the country’s future. This is so because the effectiveness and productivity of economic activities both at the Urban and rural areas depend on how people are able to move in pursuit of these activities. No Nation can be said to be developing in the absence of adequate prosperity development and investment in the economy, be it in the area of crude petroleum and gas production, agriculture, building and construction, tourism, transportation utilities and real estate and business services.
The paper is concerned with two dimensional deformation in a homogeneous, transversely isotropic thermoelastic solids without energy dissipation and with two temperatures due to various sources. Assuming the disturbances to be harmonically time-dependent, the transformed solution is obtained in the frequency domain. The application of a time harmonic concentrated and distributed sources have been considered to show the utility of the solution obtained. The transformed components of displacements, stresses and conductive temperature distribution so obtained are inverted numerically using a numerical inversion technique. Effect of anisotropy and two temperature on the resulting expressions are depicted graphically.
Introduction: Injection is an infusion method of putting drugs or fluids in to the body with a hollow needle and a syringe. The use of injection for treatment accompanied with variety of disadvantages including sepsis at administration, risk of tissue toxicity, costly difficulties in correcting the error. Injections are very expensive compared to other dosage forms and require trained personnel for administration. Moreover, unhygienic use of injections can increase the risk of transmission of potentially serious pathogens, such as hepatitis, HIV/AIDS, and blood-borne diseases. It is estimated by the WHO that about 16 billion injections are undertaken in developing countries annually and are often irrationally used. Objective: The present study was aimed to assess the prescription pattern of injections in Adama Hospital Medical College. Method: Hospital based Prospective cross sectional study was done to assess prescription pattern of injections in outpatient pharmacy of AHMC. All Prescription cards from March 24, 2015 to May 24, 2015 were taken and reviewed using pretested data collection format. Finally data was edited, coded, tallied and cleaned. Descriptive statistics was computed.
In sampling theory, regression type estimators are extensively used to estimate the population mean when the correlation between study and auxiliary variables is high. In this study, we incorporate robust modified maximum likelihood estimators (MMLEs) into regression type estimator in the presence of non-response and their properties have been obtained theoretically. For the support of the theoretical outcomes, simulations under several super-population models have been made. We study the robustness properties of these modified estimators. We show that utilization of MMLEs in estimating finite populations mean leads to robust estimates, which is very advantageous when we have non-normality or other common data anomalies such as outliers.
In this paper, we consider a non-local mixed integral equation in position and time in the space 2 L 1,1 C 0,T ;T. Then, using a quadratic numerical method, we have a system of Fredholm integral equations (SFIEs), where the existence of a unique solution is considered. Moreover, we consider Product Nystrom method (PNM), as a famous method to solve the singular integral equations, to obtain an algebraic system. Finally, some numerical results are considered, and the error estimate, in each case, is computed.
The study examined the influence of sex-role selfconcept on academic performance among students in coeducational secondary schools in Siaya District. The sample comprised 154 boys and 89 girls in Form 3. Bem’s Sex-role Inventory (BSRI) was used to collect data on masculinity and femininity while students’ academic scores were obtained from school records. Linear Regression analysis revealed that sex-role self-concept predicts academic performance. Sex-role self-concept also explained significant variance in academic scores. The results further showed significant difference between the academic mean scores of androgynous, masculine, feminine, and undifferentiated students. However, the androgynous students had better academic mean score than the other students. The results support the view that sex-role self-concept is a predictor of achievement than gender.
Shock therapy is one of the treatment methods for psychiatric patients, which is associated with a low risk and in financial terms it also benefits the patient and the health system. Mild Electroconvulsive device, which only affects the skin (and not the nervous system), operates on the basis of classical conditioning. EST device has some morphological features including the size and much weight that causes anxiety in the patient. It also has a mechanism that can be fed with 220V. Consequently, the concentration of physician is considerably reduced and also, it causes negative effects on the patient. In behavioral therapy, reducing the patient’s anxiety is a very important point that should be taken into consideration. Studying the effect of electroshock therapy on the cognitive state of patients hospitalized in the psychiatric ward showed that shortage and lack of knowledge cause fear and confusion and this, intensifies the cognitive effects that appear after the electroconvulsive therapy. Therefore, it is necessary for the nurses to provide their patients with appropriate and enough information before the implementation of this therapy. In this paper we offer a new device that consists of mild Electroconvulsive system, warning lights, warning voice, and small size and shape which has been designed on the basis of golden rate1 . Management system of the device is done via remote control and consequently, the patient doesn’t experience any anxiety in the course of treatment, rather it increases the performance of attending physician and facilitates the treatment.
In order to develop, learners need to notice either new language forms or gaps in their current knowledge. This noticing of gaps can be especially problematic for language learners when the skill of speaking is involved due to the cognitive load involved in producing utterances and also a lack of useful feedback. Too often in English courses, especially in the Middle East, there is an overreliance on decontextualized, uninteresting or irrelevant native speaker input presented in course books, and not enough time is given to opportunities for students to develop an understanding of their spoken interlanguage development. The following paper examines a learning activity in which a pair of Omani university students are recorded performing a routine split information task; this is used as the basis for a reflective noticing task whereby the learners transcribe and edit their own interaction. Aspects of these tasks such as quality of engagement, the extent to which they meet relevant conditions for learning, and the opportunities for and evidence of learning are assessed. Weaknesses found in certain aspects of the tasks are discussed, and suggestions are given to address these shortcomings.
In the Research paper I explained about working Google Web indexing, crawling and ranking algorithms. On every new day Google and other search Engines are changing their way to index and rank website. It explains the way to get ranks your website with safest way and keep your business moving towards top positions. The paper provides in-depth analysis of all big hits of Google by updates in ranking algorithms. This paper addresses this question how to make a better strategy for getting in local search.
