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   

Synthesis of singly-terminated ladder networks by multivariable array using homogeneous polynomials     

B. Raman  V. Ramachandran  M.O. Ahmad  M.N.S. Swamy 《Journal of The Franklin Institute》1982,313(6):353-372

This paper discusses a multivariable array whose elements are multivariable homogeneous polynomials which may have missing terms in any of the variables. This array permits one to obtain conditions for the realizability of a driving-point function or a transfer function as a resistively terminated low-pass ladder network. By reac- tance transformations, other forms of ladder structures can be obtained. The case of cascade-separable ladder networks is discussed in detail.  相似文献   

Examining the antecedents of e-loyalty intention in an online reservation environment     

Samar Mouakket  Mohammad Ahmad Al-hawari 《The Journal of High Technology Management Research》2012,23(1):46-57

Online reservation has increased significantly in recent years. Understanding how customers behave towards this technology is considered to be important to interested parties, such as travel agencies and tourism marketing managers, in order to enable them to improve their marketing strategies, which would, in turn, allow them to retain their customers. This paper presents findings about the antecedents of e-loyalty intention towards online reservation among 288 respondents in the United Arab Emirates. The research examines the role of e-service quality, hedonic and utilitarian values, satisfaction, and subjective norms in motivating loyalty intention towards online reservation. The results show that e-service quality has a significant influence on hedonic and utilitarian values, which, in turn, affect customer satisfaction. Moreover, satisfaction and subjective norms positively affect e-loyalty intention towards online reservation.  相似文献   

Tide–surge interaction model including air bubble effects for the coast of Bangladesh     

Gour Chandra Paul  Ahmad Izani Md. Ismail 《Journal of The Franklin Institute》2012,349(8):2530-2546

An estimate of water levels due to the interaction of tide and surge associated with a storm including air bubble effects is made along the coastal region of Bangladesh. For this purpose, a vertically integrated shallow water model in Cartesian coordinate system is developed introducing air bubbles and is solved using nested finite difference schemes. A fine grid model covering the region between 21°15′N to 23°N and 89°E to 92° E has been nested into a coarse grid model covering the region between 15°N to 23°N and 85°E to 95°E in the Bay of Bengal to incorporate all the major islands and coastal bending accurately. By applying tidal forcing through the southern open boundary of the coarse grid model appropriate tidal conditions are generated in the problem domain. Numerical experiments are performed with the help of the model to simulate water levels due to tide and surge interaction including air bubble effects associated with the tropical storm of April 1991. The model results are found to be reasonable and the model can be found to simulate higher water levels in the presence of air bubbles.  相似文献   

Effectiveness of public and private sector agricultural extension: Implications for privatisation in Pakistan     

Andrew P. Davidson  Munir Ahmad 《The Journal of Agricultural Education and Extension》2013,19(3):117-126

Worldwide serious reservations are being expressed about the ability and competency of the public sector to deliver agricultural extension services, especially in developing countries such as Pakistan which is faced with serious financial difficulties. Consequently, the government is looking for alternative extension paradigms that are cost-effective and client-oriented. To this end the government of Pakistan is inclined towards privatizing the provision of agricultural extension services as a means to promote a second ‘Green Revolution’. This study was conducted among cotton farmers in the Punjab Province to examine the comparative effectiveness of public and private sector extension as perceived from the stakeholders. Data were collected from 52 contact farmers of both extension systems. A number of biases were identified in both systems; namely, a preference for farmers with better education and larger landholdings than their noncontact farmer counterparts. Overall, neither system appears to be working for the benefit of the wider farming community.  相似文献   

Physical and psychosocial aspects of the learning environment in the science laboratory and their relationship to teacher satisfaction     

Che Nidzam Che Ahmad  Kamisah Osman  Lilia Halim 《Learning Environments Research》2013,16(3):367-385

This paper is a report of a survey conducted to determine teachers’ perception of the science laboratory learning environment and the relationship between different aspects of this environment and satisfaction from teaching and learning. Teachers’ perceptions of psychosocial aspects were measured by use of the Science Laboratory Environment Inventory (SLEI), whereas perceptions of physical aspects were measured by use of the Physical Science Laboratory Environment Inventory. The level of satisfaction was measured by use of a satisfaction scale (SC). Data were collected from 800 science teachers in secondary schools in Malaysia. Analysis of findings revealed that teachers have positive attitudes on all SLEI scales, with the exception of the open-ended scale. In terms of physical aspects, teachers regard lighting and technology as highly important but furniture and equipment, space, air quality and safety as of moderate importance only. Results also showed that teachers’ satisfaction from teaching in the laboratory was positive. Subsequent analysis revealed a significant predictive relationship between teachers’ perception of science laboratory learning environments and their teaching and learning satisfaction.  相似文献   

School‐to‐work transition services for students with disabilities in Malaysia: organisations' views on policy and practices     

Melissa Ng Lee Yen Abdullah  See Ching Mey  Tan Kok Eng  Rosly Othman  Ahmad Fairuz Omar 《Journal of Research in Special Educational Needs》2013,13(4):259-271

Transition services are required by law for students with disabilities in many developed countries. In Malaysia, however, there is still no specific legislation mandating that school‐to‐work transition planning and services be provided to students with disabilities. This study investigated the state of the transition services provided by educational organisations to students with disabilities in Malaysia. A mixed method research design, which utilises both quantitative and qualitative research techniques, was employed to obtain information from 23 government organisations and NGOs involved in the education and training of students with disabilities. This study found that the organisations surveyed were aware of the lack of transition support and call attention to the importance of instituting a national policy on school‐to‐work transition services and supported employment systems for students with disabilities. The legislative and educational implications for Malaysia are discussed.  相似文献   

Dynamic modeling and nonlinear control strategy for an underactuated quad rotor rotorcraft     

Ashfaq Ahmad Mian  Dao-bo Wang 《浙江大学学报(A卷英文版)》2008,9(4):539-545

In this paper, a nonlinear dynamic MIMO model of a 6-DOF underactuated quad rotor rotorcraft is derived based on Newton-Euler formalism. The derivation comprises determining equations of motion of the quad rotor in three dimensions and seeking to approximate the actuation forces through modeling of the aerodynamic coefficients and electric motor dynamics. The derived model is dynamically unstable, so a sequential nonlinear control strategy is implemented for the quad rotor. The control strategy includes exact feedback linearization technique, using the geometric methods of nonlinear control. The performance of the nonlinear control algorithm is evaluated using simulation and the results show the effectiveness of the proposed control strategy for the quad rotor rotorcraft near quasi-stationary flight.  相似文献

Cord Blood Insulin Levels: It’s Correlation with Gender,Birth Weight and Placental Weight in Term Newborns     

Afzal Ahmad  Rukmini Mysore Srikantiah  Charu Yadav  Ashish Agarwal  Poornima Ajay Manjrekar  Anupama Hegde 《Indian journal of clinical biochemistry : IJCB》2016,31(4):458-462

The cause of more insulin resistance in female than males are still unknown. To know the cause from early life, normal values of relevant parameters are required. So, aim of this study was to determine the reference levels of glucose and insulin in cord blood of term newborns and to examine their effects on gender, placental and birth weight of term newborns. In cross sectional study 60 consecutive term newborns were included from constituent hospitals. Placental and birth weights were measured and cord blood was collected for estimation of serum insulin and plasma glucose. Plasma glucose estimation was done by auto analyzer (GOD–POD method) and serum insulin analysis was done using Insulin ELISA Kit. After analysis, mean ± 2SD used for estimating cord blood insulin and glucose levels, which were 10.1 ± 7.8 μIU/mL and 67.8 ± 33.8 mg/dL respectively. Correlation of insulin with both birth weight and placental weight were r = 0.359 and 0.41 respectively; p < 0.001. Interestingly we found higher insulin levels in females as compared to male newborns in spite of having lower birth weight in them. In conclusion this study reported the levels of insulin and glucose in cord blood of term newborns. Incidentally, this is the first study as per our knowledge to report significant correlation between cord blood insulin, glucose with birth weight, placental weight and gender in south India. Female newborns had higher insulin levels than males, despite lesser birth weight can be attributed to intrinsic insulin resistance in them.  相似文献
