ICT in Science Education: A quasi‐experimental study of achievement,attitudes toward science,and career aspirations of Korean middle school students     

HyeRan Park  Samia Khan  Stephen Petrina 《International Journal of Science Education》2013,35(8):993-1012

The Seventh School Curriculum Reform in Korea was introduced in 2000 to prepare school‐aged Koreans for an information and knowledge‐based society. The reform effort emphasises information and communication technology (ICT) in the K–12 curriculum and a learner‐centred pedagogy. This study examines the contributions of ICT, specifically, computer‐assisted instruction (CAI), in Korean science classrooms. A sample of 234 Korean middle school students was categorised into five achievement groups. Data were collected from pre‐ and post‐achievement test scores and pre‐ and post‐questionnaires for attitudes toward science, future courses, and career aspirations in science. Findings include: (1) the lowest achievement group showed the most significant improvement after CAI (p=.000); (2) an improvement in student achievement in science significantly influenced students’ attitudes toward science (p=.019), future course selections, and career aspirations related to science (p=.000); and (3) boys tended to perform better with CAI than girls. This research provides evidence that CAI has the potential to help lower achieving students in Korean science classes and may encourage enrolment in science.  相似文献   

Construction of nationhood through education in Malaya: revisiting the Barnes and Fenn-Wu Reports     

Moses Samuel  Mahmud Hasan Khan 《Asia Pacific Journal of Education》2013,33(3):249-260

This article provides an analysis of two colonial reports, the Barnes and the Fenn-Wu Reports on education in the British colony of Malaya. The popular stance on the Barnes and the Fenn-Wu Reports is that one is an effect or reply to the other. We argue on the contrary that the two reports construct a common argument on nation-building which becomes apparent through a dialogic reading of the reports. We show how the two reports, written in the 1950s, reflect the anxiety of the colonial rulers in constructing a nation and the ethnic communities (the Malays and the Chinese) in pre-independent Malaya. These communities were constructed not without their inherent antagonism as well as their reciprocal vulnerabilities in a future political state. This act of articulation is predominantly a political act constructed through a complex web of interdiscursivity and intertextuality. The spectres of the Barnes and the Fenn-Wu Reports continue to surface in education and nation-building discourse in modern-day Malaysia.  相似文献   

Oxygen free radical modified DNA: Implications in the etiopathogenesis of Systemic lupus erythematosus     

Saba Khan  Roshan Alam  Moinuddin  Asif Ali 《Indian journal of clinical biochemistry : IJCB》2009,24(2):123-130

The present study was designed to probe the possible role of singlet oxygen and superoxide anion radical modified DNA in the etiopathogenesis of Systemic lupus erythematosus. These species were generated by the exposure of riboflavin to 365 nm UV light. Modified DNA showed single strand breaks, hyperchromicity at 260nm and decrease in Tm. The modified DNA induced high titer antibodies in experimental animals. The antibodies showed reactivity with various nucleic acid polymers, a property commonly associated with Systemic lupus erythematosus anti-DNA autoantibodies. Systemic lupus erythematosus sera showed preferential binding of modified DNA over native DNA in direct binding and competitive binding solid phase immunoassays and band shift assays. The results suggest for the possible involvement of the singlet- superoxide modified DNA as a potential trigger for anti- DNA autoantibody production in SLE and thus in the etiopathogenesis of the disease.  相似文献

Challenging the myths about madaris in Pakistan: A national household survey of enrolment and reasons for choosing religious schools     

Anne Cockcroft  Neil Andersson  Deborah Milne  Khalid Omer  Noor Ansari  Amir Khan  Ubaid Ullah Chaudhry 《International Journal of Educational Development》2009

There is speculation about madaris in Pakistan as sources of terrorists and about levels and reasons for enrolment, but a dearth of empirical data. We studied madarsah enrolment among 53,960 representative households; 853 focus groups of parents discussed enrolment choices. In 2004, 2.6% of all children (3.8% of school-going children) aged 5–9 years attended a madarsah. Children from urban and less educated households were more likely to attend a madarsah, but there was no difference by sex of the child or household vulnerability. Parents chose madaris because they offered an Islamic education. Our findings challenge misconceptions about madaris in Pakistan.  相似文献

Mitigating the urban–rural educational gap in developing countries through mobile technology-supported learning     

Sharifullah Khan  Gwo-Jen Hwang  Muhammad Azeem Abbas  Arshia Rehman 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(2):735-749

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

Genetic basis of heterosis and inbreeding depression in rice (<Emphasis Type="Italic">Oryza sativa</Emphasis> L.)     

Alam?M.?F.?Email author  Khan?M.?R.  Nuruzzaman?M.  Parvez?S.  Swaraz?A.?M.  Alam?I.  Ahsan?N. 《浙江大学学报(A卷英文版)》2004,5(4):406-411

The genetic basis of heterosis was studied through mid-parent, standard variety and better parent for 11 quantitative traits in 17 parental lines and their 10 selected hybrids in rice (Oryza sativa L.). The characters were plant height. days to flag leaf initiation, days to first panicle initiation, days to 100% flowering, panicle length, flag leaf length. days to maturity, number of fertile spikelet/panicle, number of effective tillers/hill, grain yield/10-hill, and 1000-grain weight. In general the hybrids performed significantly better than the respective parents. Significant heterosis was observed for most of the studied characters. Among the 10 hybrids, four hybrids viz., 17A×45R, 25A×37R, 27A×39R, 31A×47R, and 35A×47R showed highest heterosis in 10-hill grain yield/10-hill. Inbreeding depression of F₂ progeny was also studied for 11 characters of 10 hybrids. Both positive and negative inbreeding depression were found in many crosses for the studied characters, but none was found significant. Selection of good parents was found to be the most important for developing high yielding hybrid rice varieties.

The use of clickers in Instrumentation and Control Engineering education: a case study     

Asiya Khan  Priska Schoenborn  Sanjay Sharma 《European Journal of Engineering Education》2019,44(1-2):271-282

ABSTRACT

This paper presents results from a small-scale study of third-year Instrumentation and Control Engineering (n?=?37) at the University of Plymouth. The aim of the study was to enhance student learning and increase participation via the use of clickers. Clickers allow for student participation anonymously. The lecture content was modified to embed clicker questions at regular intervals to test knowledge, understanding and cognitive skills. Largely, the students preferred interactive lectures to traditional didactic lectures and using clickers increased student engagement and participation. Interestingly, compared to assessment results from the previous year, the increased level of engagement did seem to lead to an overall improvement in grades of approximately 10% in the subject of Control Engineering. However, in Instrumentation, the average fell by approximately 20%. One possible contributory factor of this drop could be the changed exam format for Instrumentation only. This year, the multiple choice section was removed from the Instrumentation examination paper. Furthermore, an analysis of variance showed that in addition to using clickers in the lectures, attendance plays a key role. Results of this small-scale study show that for a more complex subject like Control, student learning, engagement and attainment can increase by the use of clickers.  相似文献
