Developing a mathematics curriculum to improve learning behaviors and mathematics competency of children     

Nahid Shirani Bidabadi  Ebrahim Mirshah Jafari  Ahmad Abedi 《The Journal of educational research》2019,112(3):421-428

The authors investigated the effect of a mathematical curriculum (CU) developed based on verbal and practical activities on the mathematical competency (MC) and learning behaviors (LB) of preschool children. In a quasi-experimental design, 60 children (5- to 6-year-old girls) were selected using the accessible sampling method. The children were randomly divided into an experimental group and a control group, and the relevant concepts were taught to the children in both groups. While the control group received the typical kindergarten education based on the usual textbooks and worksheets, the CU was taught to the experimental group. Structural equation modeling was used to model the data and statistical evaluation. The results demonstrated a significant difference between the two groups in MC and LB. The CU significantly improved MC directly, and indirectly through the improvement of LB (i.e., engagement and learning focus, verbal behaviors, and type of activity).  相似文献   

Teachers’ perceptions of the benefits and the challenges of integrating educational robots into primary/elementary curricula     

Ahmad Khanlari 《European Journal of Engineering Education》2016,41(3):320-330

Twenty-first century education systems should create an environment wherein students encounter critical learning components (such as problem-solving, teamwork, and communication skills) and embrace lifelong learning. A review of literature demonstrates that new technologies, in general, and robotics, in particular, are well suited for this aim. This study aims to contribute to the literature by studying teachers' perceptions of the effects of using robotics on students' lifelong learning skills. This study also seeks to better understand teachers' perceptions of the barriers of using robotics and the support they need. Eleven primary/elementary teachers from Newfoundland and Labrador English Schools District participated in this study. The results of this study revealed that robotics is perceived by teachers to have positive effects on students' lifelong learning skills. Furthermore, the participants indicated a number of barriers to integrate robotics into their teaching activities and expressed the support they need.  相似文献

Resource discovery in distributed digital libraries through visual knowledge navigation     

GU Qian-yi AHMAD Faisal SUMNER Tamara 《浙江大学学报(A卷英文版)》2005,6(11):1306-1311

INTRODUCTION In this paper, we present our work in the Strand Map Service (SMS), which provides concept map based browsing interfaces for resource discovery in a library independent manner within American Na- tional Science Digital Library (NSDL). As critical components of digital libraries, dis- covery systems provide interfaces that support user to search and browse for resources in digital libraries (Hall et al., 1999). The effectiveness of discovery systems has big impact on the…  相似文献   

Generalized filtering of one-sided Lipschitz nonlinear systems under measurement delays     

Sohaira Ahmad  Muhammad Rehan 《Journal of The Franklin Institute》2017,354(13):5589-5616

This paper addresses the filtering problem for the one-sided Lipschitz nonlinear systems under measurement delays and disturbances using a generalized observer. A generalized architecture for filtering of the one-sided Lipschitz nonlinear systems with output delays is explored, which exhibits diverging manifolds, namely, the conventional static-gain filter and the dynamical filter, and can be employed to render robust stability of the filtering error dynamics. A matrix inequality based framework is obtained by employing a Lyapunov?Krasovskii (LK) functional, whose derivative is exploited through Jensen's inequality, one-sided Lipschitz condition, quadratic inner-boundedness inequality and range of the measurement delay, resulting into L₂ stability for the filtering error system. Generalized filter design for the Lipschitz nonlinear systems with delayed outputs and specific results for the delay-dependent and delay-rate-independent filtering schemes for the one-sided Lipschitz nonlinear systems are deduced from the proposed approach. Convex optimization techniques are employed to achieve a solution for the nonlinear constraints through linear matrix inequalities by employing cone complementary linearization approach. Illustrative numerical examples to demonstrate the effectiveness of proposed method are provided.  相似文献   

Human governance: A neglected mantra for continuous performance improvement     

Arfah Salleh  Aziuddin Ahmad  Naresh Kumar 《Performance Improvement》2009,48(9):26-30

Every individual should be entrusted with an internal driver to strive their best towards achieving their potential and to manifest their performance through innovative means. This can be reached only under circumstances where the abstract human values and principles are recognized and indoctrinated in the culture. The strategies discussed in this article will serve as input in proposing the areas of focus toward the practice of human governance.  相似文献

Practising mental rotation using interactive Desktop Mental Rotation Trainer (iDeMRT)     

Ahmad Rafi  Khairulanuar Samsudin 《British journal of educational technology : journal of the Council for Educational Technology》2009,40(5):889-900

An experimental study involving 30 undergraduates (mean age = 20.5 years) in mental rotation (MR) training was conducted in an interactive Desktop Mental Rotation Trainer (iDeMRT). Stratified random sampling assigned students into one experimental group and one control group. The former trained in iDeMRT and the latter trained in conventional condition. A multifactorial pretest posttest design procedure was used and data were analysed using two-way analysis of covariance. Overall, there was substantial improvement in MR accuracy. Main effects of training and gender were observed, indicating that iDeMRT group and boys outperformed the control group and girls respectively. In addition, an interaction between training method and gender was present, indicating that boys were more accurate when trained in iDeMRT and performed moderately in conventional method. Female participants achieved equivalent improvement gain in MR accuracy regardless of the training conditions used. For the speed measure of MR, no appreciable improvement was observed after training.  相似文献   

Higher education in Federally Administered Tribal Areas of Pakistan after 9/11： Problems and prospects     

Syed Hafeez Ahmad Fatima A. Junaid 《美中教育评论》2010,7(5):55-65

The troubled state of affairs in the Federally Administered Tribal Areas （FATA） of Pakistan portends serious repercussions and grave consequences, destined to affect education particularly higher education in the entire tribal belt. Ironically, no extensive study has been conducted, to investigate those dimensions of FATA higher education which have been adversely affected in the aftermath of 9/11. This exploratory study examines those areas which have been badly affected as a result of current turmoil. In fact, the higher education in FATA has its own peculiar dynamics. Inherently, the entire tribal region has very few well-maintained and properly equipped colleges. Lack of adequate educational facilities, multiplied poor security environment has aggravated the entire situation. Law and order situation in the region has undermined the already dilapidated monitoring mechanism of education department. This state of affairs provides breeding ground for extremist propensities and radical tendencies. In reality, very little attention has been devoted to reform the education system in tribal areas. The whole set up needs to be rehabilitated by taking recourse due to the proactive role of international community. The paper concludes with recommendations for policy makers besides offering new avenues for further research.  相似文献
