One form of educational inequality is the disparity that exists between urban and rural settings. Equal distribution of quality education is a challenge for developing countries due to the unavailability of resources. Various approaches to equal distribution are distance learning, telecast learning and e-learning; however, these approaches cannot achieve the desired objectives due to their limitations. This research aimed to investigate the interesting question of whether mobile technology can bring urban and rural settings closer together. A mobile application for learning Urdu grammar was designed to measure the learning gains of fourth-grade students at two different schools from urban and rural settings. A quantitative technique, the quasi-experimental pre-test and post-test method, was used to measure the effectiveness of the mobile application. The comparison of the students’ performances at the urban and rural schools illustrated the role of mobile technology in mitigating the educational gap. The present study provides evidence that children from different social backgrounds may benefit equally from mobile technology.  相似文献   

Chip morphology predictions while machining hardened tool steel using finite element and smoothed particles hydrodynamics methods

Chip morphology predictions in metal cutting have always been challenging because of the complexity of the various multiphysical phenomena that occur across the tool-chip interface. An accurate prediction of chip morphology is a key factor in the assessment of a particular machining operation with regard to both tool performance and workpiece quality. Although finite element (FE) models are being developed over the last two decades, their capabilities in modeling correct material flow around the tool tip with shear localization are very limited. FE models with an arbitrary Lagrangian Eulerian (ALE) approach are able to simulate correct material flow around the tool tip. However, these models are unable to predict any shear localization based on material flow criteria. On the other hand, FE models with a Lagrangian formulation can simulate shear localization in the chip segments; they need to make use of a mesh-based chip separation criterion that significantly affects material flow around the tool tip. In this study a mesh-free method viz. smoothed particles hydrodynamics (SPH) is implemented to simulate shear localization in the chip while machining hardened steel. Unlike other SPH models developed by some researchers, this model is based on a renormalized formulation that can consider frictional stresses along the tool-chip interface giving a realistic chip shape and material flow. SPH models with different cutting parameters are compared with the traditional FE models and it has been found that the SPH models are good for predicting shear localized chips and do not need any geometric or mesh-based chip separation criteria.  相似文献   

Parent-Infant Rough Play: Its Cultural Specificity     

Jaipaul L. Roopnarine  Mohammed Ahmeduzzaman  Ziarat Hossain  Nancy Beth Riegraf 《Early education and development》1992,3(4):298-311

The salience of father-infant rough play in some industrialized and nonindustrialized countries around the world was reviewed, and data were presented on the physical play interactions of 34Indianmothers and fathers with their year-old infants in the home. Our review of the parent-infant physical play literature failed to show that fathers had a uniformly greater propensity to engage in vigorous rough activity with infants than mothers did. The data from the observational study suggest that Indian parents are not vigorous play partners to infants. Mothers were more likely to engage in object-mediated play than were fathers. In total, the data reviewed do not support the contention that rough play is a major activity between fathers and infants across cultures. Rather, the data from parent-infant play in the nonindustrialized countries suggest that rough play may be culture specific, casting doubts about its biological underpinnings.  相似文献   

Using think-aloud protocols and interviews in investigating writers’ composing processes: combining concurrent and retrospective data     

Muhammad M. M. Abdel Latif 《International Journal of Research & Method in Education》2019,42(2):111-123

Research comparing the use of retrospective interviews (RIs) and think-aloud protocols (TAPs) as two data sources of writers’ composing processes is almost nonexistent. Trying to address this research gap, the present study examined the data obtained from the task-specific RIs and TAPs about the composing processes of 30 second language (L2) writers. Each participant thought aloud by concurrently verbalizing thoughts while performing an argumentative writing task, and then was interviewed immediately after the think-aloud session about their composing processes. The RI and TAP data was analyzed and compared in terms of five aspects of L2 writers’ composing: pre-writing stage, while-writing planning, first language (L1) use, composing problems and problem-solving, and text reviewing and changing. Though the results generally indicate that concurrent verbalizations provide much richer data than RIs about L2 writers’ composing processes, RIs were found to be a valuable source for revealing the ‘why’ of such processes. Besides, the gap between the data provided by the two sources differed from one composing aspect to another. Recommendations for how to optimally combine and make use of the two data sources in writing process research are provided.  相似文献   

Islam in Bangladesh politics: the role of Ghulam Azam of Jamaat-I-Islami     

Ishtiaq Hossain  Noore Alam Siddiquee 《Inter-Asia Cultural Studies》2013,14(3):384-399

Abstract

In recent years, Islam has emerged dramatically in the politics and news headlines of the world. As elsewhere in the Muslim World, the impact of the Islamic resurgence movement is clearly visible in contemporary Bangladesh. Organized and led by Ghulam Azam until very recently, the Jamaat is now the largest and most active Islam-based political party in Bangladesh. This paper attempts to analyse the politics of Jamaat, with reference to Ghulam Azam and his political ideas and thought. First, this paper attempts to put Jamaat-I-Islami within the context of Bangladesh politics. We then provide a short biographical sketch of Ghulam Azam, showing his exposure to both Western and Islamic educations and their impact on his political activities. This paper next focuses on some of his political ideas and contributions and analyses them in the light of contemporary socio-political realities in Bangladesh, demonstrating the significant and controversial impact of his political activism and strategies on contemporary Bangladesh politics and society. The paper concludes that neither Ghulam Azam nor his party has been able to change generally negative perception about Jamaat and thus significantly widen its acceptance among the masses. Rather, at times, comments of Jamaat leadership like ‘we did no mistakes in 1971’ have infuriated the nationalist and patriotic forces and widened the gap between Jamaat and common people. It remains to be seen how Ghulam Azam and the new Jamaat leadership tackle these challenges in future.  相似文献

Electronic resources and services in Pakistani university libraries: A survey of users' satisfaction     

Muhammad Sajid Mirza  Khalid Mahmood 《International Information and Library Review》2012,44(3):123-131

This study is an attempt to evaluate the effectiveness of electronic resources and services in Pakistani university libraries on the basis of users' satisfaction. A survey method was employed to conduct the research. Using convenience sampling, eight university libraries; four each from Islamabad and Lahore including two from the public sector and two from the private sector having IT applications, were included in the users survey. The total population (i.e., 40,236) of library users was very large; therefore, a reasonable, manageable and convenient sample of 800 library users, including 100 users each from the eight libraries was selected. A semi structured questionnaire was designed to collect data, while a five-point Likert Scale from 1 (Dissatisfied) to 5 (Extremely satisfied) was used to measure the satisfaction level of the respondent. The study concluded that Pakistani university libraries are offering effective electronic resources and services to their users.  相似文献
