Intrinsic Factors for Continued ERP Learning: A Precursor to Interdisciplinary ERP Curriculum Design     

Kuanchin Chen  Muhammad Razi  Thomas Rienzo 《Decision Sciences Journal of Innovative Education》2011,9(2):149-176

Unilateral enterprise resource planning (ERP) curriculum improvements from the instructor's perspective are likely to generate only limited success. Understanding student motivations and beliefs with ERP systems is the missing link to effective ERP education. Relatively little attention in the ERP literature has been given to student learning associated with ERP experience, and almost none to factors influencing current and expected student beliefs and behaviors relative to ERP. The complexity of ERP systems demands that beliefs and behaviors be considered when planning ERP curricula. In the present study, the Theory of Planned Behavior was extended to examine students’ intentions to explore additional aspects of ERP after their class exercises. When considering all students, attitude and subjective norm had positive and significant effects on intentions to continue ERP learning. Subjective norm also affected attitude, and availability of support materials had a positive effect on subjective norm. Distinctive patterns are found for the construct relationships between student groups who valued ERP education (the engaged) and those who placed little or no value on ERP education (the undecided). Results from competing model analyses indicate that support materials influenced the engaged and undecided groups differently. Strategies for ERP curriculum design are provided.  相似文献

Transforming public schools: Impact of the CRI program on child learning in Pakistan     

Muhammad Farooq Naseer  Manasa Patnam  Reehana R. Raza 《Economics of Education Review》2010,29(4):669-683

This paper evaluates the impact of teaching innovations, introduced in public primary schools under the Children Resources International (CRI) Program, on student outcomes. We estimate students’ learning based on their scores on standardized tests. We match schools and children within the treatment and comparison group and find that the CRI Program has been effective in raising learning achievement. Moreover, the results are robust to unobserved selection bias. The average gain for a CRI student represents an improvement of 0.40 standard deviations. The results stay unchanged when we use alternative estimators for the treatment effect including the bias-corrected estimator proposed by Abadie and Imbens (2006).  相似文献   

Gender Difference in Teachers’ Mathematical Knowledge for Teaching in the Context of Single-Sex Classrooms     

Haroun  Ramzi F.  Ng  Dicky  Abdelfattah  Faisal A.  AlSalouli  Misfer S. 《International Journal of Science and Mathematics Education》2015,14(2):383-396

This study examines gender differences of teachers on their mathematical knowledge for teaching in the context of single-sex classrooms in Saudi Arabia. A translated version of the Mathematical Knowledge for Teaching (MKT) instrument (Learning Mathematics for Teaching [LMT], 2008) in Number and Operation Content Knowledge (CK) and Knowledge of Content and Student (KCS) scales were administered to 197 teachers (146 male and 51 female). Two-sample t test and multiple regression were conducted to compare the two groups and test the effect of teacher background variables. Female teachers significantly scored better than their male counterpart. Gender, years of teaching experience, and specialization significantly predicted teachers’ content knowledge, F(3, 187) = 13.180, explaining 41.8 % of the variance. Only gender and specialization significantly predicted teachers’ knowledge of content and student, F(2, 191) = 6.335, explaining 24.9 % of the variance. Further comparing items in the MKT instrument where female teachers outperformed male teachers confirmed that female teachers were better in attending to the content knowledge in the context of student’s learning.

Parameter-dependent finite-time observer design for time-varying polytopic uncertain switched systems     

Muhammad Naveed Iqbal  Jian Xiao  Weiming Xiang 《Journal of The Franklin Institute》2014

Mathematical models are an approximate of physical systems and design procedures are only complete when modeling errors have been quantified. Uncertainties are incorporated in design procedure to compensate such discrepancies and to add robustness. This paper investigates the design problem of parameter-dependent switched observers   for polytopic uncertain switched systems. State-space model is considered subject to time-varying uncertainties, and designated observer gains ensuring stability of overall system are also parameter-dependent. Synthesis procedure is demonstrated by employing _?∞${?}_{\infty }$ performance criteria which has become a standard for robust system design against external disturbances. This investigation is carried out in the framework of finite-time stability (FTS) and finite-time boundedness (FTB) which is the focus of researchers recently because of its apparent practical significance, especially after the emergent utilization of linear matrix inequalities.  相似文献   

Use of digital game based learning and gamification in secondary school science: The effect on student engagement,learning and gender difference     

Amna Khan  Farzana Hayat Ahmad  Muhammad Muddassir Malik 《Education and Information Technologies》2017,22(6):2767-2804

This study aimed to identify the impact of a game based learning (GBL) application using computer technologies on student engagement in secondary school science classrooms. The literature reveals that conventional Science teaching techniques (teacher-centered lecture and teaching), which foster rote learning among students, are one of the major concerns in Pakistan Education system. This leads to student disengagement in science lessons eventually resulting in student absenteeism and dropouts from the schools. This study consisted of five stages: (1) examining the impact of Digital Game-Based Learning (DGBL) and gamification on engagement, learning and gender difference, and literature related to using DGBL models for instructional design; (2) planning learning activities and developing a GBL application based on a specific content in Science; (3) conducting an intervention with a sample of 72 participants of 8th grade (aged 12–15) in a low cost private school of Pakistan following quasi-experimental research framework; (4) observing behaviour and emotions of the participants during science lessons; (5) conducting pre and post tests to assess the learning outcomes of participants followed by focus groups discussion. Analysis from Friedman test, Mann-Whitney U test, and Wilcoxon Signed Rank test show that the GBL application has a positive influence on student engagement. However, GBL application was not equally effective for all students since girls outperformed boys in terms of engagement and learning outcomes. This study gives insights into the development of better educational games to promote student learning.  相似文献   

Feasibility of determination of fertile period in Indian women based on urinary hormone estimations     

Meena Desai  U. M. Donde  M. Ikram Khatkhatay 《Indian journal of clinical biochemistry : IJCB》2001,16(1):127-131

Baseline data available on the excretory profiles of estrone giucuronide (E₁G), pregnanediol glucuronide (PdG) and luteinising hormone (LH) on human menstrual cycles (n=104) was retrospectively analysed for identifying the limits of fertile period (FP) to be used as natural method of family planning. The limits of fertile period are suggested based on centile distribution of E₁G and PdG levels during defined phase of menstrual cycle. Two approaches, which do not involve any mathematical calculation are suggested. In approach A, fertile period is said to have started when E₁G value of 35 ng/ml is reached and is said to have ended when the PdG value of 2 μg/ml on two consecutive days is obtained. The criteria were applied to 30 test cycles in whom authentic fertile period was identified based on excretory profiles of E₁G, PdG and LH throughout the menstrual cycles. When approach A was followed the authentic fertile period was covered in 27 cycles giving an accuracy of 90% with a mean fertile period length of 9.11+1.9 days. In approach B, the cut off limit of E₁G value was increased to 55 ng/ml in order to reduce the days of abstinence. Though the length of the fertile period was reduced to 7.2+1.5 days the accuracy of the approach was 66.6%. Thus the approach A which has accuracy of 90% may appeal to determined couples who wish to practice family planning by periodic abstinence or restrict the use of barrier methods.  相似文献   

Approaches to studying and perceptions of the academic environment among university students in Pakistan     

Raza Ullah  Muhammad Hafeez 《Compare》2011,41(1):113-127

There has been a paucity of research on the experiences of students at Pakistani universities. A survey of over 900 students at two universities examined their approaches to studying and perceptions of their courses. Evidence was obtained for a deep approach, a surface approach and two aspects of a strategic approach. Their perceptions were based upon the instructional practices, the acquisition of generic skills, the appropriateness of the assessment and of their workload, and the available learning resources. A higher‐order analysis revealed two broad dimensions of the student experience in Pakistan. Students who had positive perceptions tended to adopt a deep approach, to prefer courses, teaching and assessment that supported their understanding and to be engaged and reliable in their studies. However, students who had negative perceptions tended to adopt a surface approach and to prefer courses, teaching and assessment that reinforced this approach through the bare transmission of information.  相似文献   

Multi-physics modelling and sensitivity analysis of olympic rowing boat dynamics     

Andrea Mola  Mehdi Ghommem  Muhammad Hajj 《Sports Engineering》2011,14(2-4):85-94

A multidisciplinary approach is implemented to model and analyse the performance of Olympic rowing boats. A reduced-order model that couples rowers motions with the hull, oars and hydrodynamic and hydrostatic forces is detailed. This model is complemented with a sensitivity analysis carried out by means of a non-intrusive polynomial chaos expansion. Sensitivity analysis results for two different boat classes, namely, a lightweight single scull and a coxless four are presented and discussed. This analysis contrasts, for both classes, the effects of varying forces exerted by the rowers, weights of rowers and cadence of motions on the boat performance.  相似文献
