ABSTRACT

Information and Communication Technologies (ICT) have had significant impacts on many sectors in today’s knowledge economy. In developing and emerging countries, ICT have enhanced equity, quality, and efficiency in the education sector. However, the adoption of ICT in the South Asian countries’ education sector has not been at scale and its impacts have been limited. There are several gaps and issues that are hindering the wider adoption of ICT and limiting its impacts in the education sector. Through the case studies of the adoption of ICT for education in Bangladesh and Nepal, this paper examines the gaps and issues to be addressed in order to better leverage ICT to enhance education equity, quality, and efficiency. This discussion is guided by the ICT in the education framework that has been developed by the authors, and could provide insights into the state of ICT in education and offer strategies to better leverage ICT for the education sector of other countries in South Asia and the region.  相似文献

This paper reports an experimental study into the effects of cooperative and individualistic approaches in teaching Mathematics and English. The study was conducted at a Vacation Learning Camp (VLC) which was held for two weeks in one of the secondary schools in Singapore. This VLC was targeted at Secondary One pupils who were classified as below average based on general ability streaming.

The individualistic teaching approach was assumed to contribute to individual efforts while the cooperative teaching approach was expected to produce cooperativeness among the subjects. The results indicated that there were no significant differences in performances in the main effects classified as the treatment groups and the sex groups in both Mathematics and English; in Mathematics, the individualistic teaching approach was more effective for the male pupils whereas the cooperative teaching approach was more effective with females. However, in English, the results were reversed.

The female pupils in the cooperative group seemed to have improved in their attitude towards learning Mathematics whereas the male pupils in the individualistic group seemed to have a more positive attitude towards learning English.  相似文献

This article explores the findings of a small research study that asked writers to describe a meaningful, personal incident using first narrative and then poetic forms. The poetry raised many anxieties about writing, including the revelations of subjectivity and the risks in sharing such work with a group. To understand some of the complexities of these responses, the researchers thought of writing as an ecology with interdependent systems influencing the writing. Rereading the research texts, they traced some of those systems that affect students' writing and understanding of poetry.  相似文献

This study evaluates the use of an open‐ended question to determine students' knowledge structure on the topic of galvanic cells. The open‐ended question was developed and administered to 163 Grade 10 students who had earlier completed a course on electrochemistry. Students' responses were marked as well as coded on the basis of the fields identified from their responses. This was then evaluated statistically to determine the collective knowledge structure of the sample of students. The knowledge structure thus mapped contains both canonical concepts and alternative conceptions (ACs). An important finding emerging from this study is that instructors need to focus student's attention on the dynamic processes involving electrons and ions during the operation of galvanic cells. In order for students to fully understand how a galvanic cell operates, they need to see the whole picture. There are three critical components that lead to students' understanding of how an oxidation–reduction reaction can generate energy and how a circuit is complete: transfer of electrons during oxidation–reduction half‐reactions, flow of electrons within metals, and migration of ions in solution. Also, we found that it is possible for students to use correct chemistry concepts in an incorrect way by establishing linkages among these in an inappropriate manner. We reiterate that apart from evaluating students' ACs, it is also important to evaluate the links between the concepts and conceptions present in students' knowledge structure so that teaching can be made more effective.  相似文献

   本文根据我国薯蓣属(Dioscorea L.)根状茎组(Sect.  Stenophora Uline)的外部形态特征、细胞染色体数、花粉形态、植物化学成分、地理分布等的规律,证明根状茎组是该属中的一个比较原始的自然类群:1.具横走的多年生地下根状茎,其它组是一年生或多年生的块茎;2.大部分是2倍体,其它组是多倍体;3.花粉粒单沟型,外壁纹饰网纹或颗粒条纹,其它组为双沟型,外壁纹饰网纹;4.含甾体皂甙元(steroidal sapogenin),其它组不含。   我们的研究观察证明,N.N.TepaCNMeHKO根据R.Knuth系统(1924)提出的薯蓣皂甙元在该属中无分布规律的说法是无充分依据的。   本文讨论了某些组或种的划分及系统位置:取消sect.Illigerestrum Prain et Burk.;将马    肠薯蓣(D.simulans Prain et Burk.)改属根状茎组;触丝薯蓣(D.tentaculigera Prain et Burk.)应列入顶生翅组  (Sect.shannicorea Prain et Burk.),  并提出了盾叶薯蓣  (D. zingiberensis  Wright)和穿龙薯蓣(D.nipponica Makino)种的划分和定名的意见。  相似文献

The present study examined the role of verbal working memory (memory span and tongue-twister), two-character Chinese pseudoword reading (two tasks), rapid automatized naming (RAN) (letters and numbers), and phonological segmentation (deletion of rimes and onsets) in inferential text comprehension in Chinese in 31 less competent comprehenders compared with 37 reading comprehension control students and 23 chronological age controls. It was hypothesized that the target students would perform poorly on these cognitive and linguistic tasks as compared with their controls. Furthermore, verbal working memory and pseudoword reading would explain a considerable amount of individual variation in Chinese text comprehension. RAN would have a nonsignificant role in text comprehension. Structural equation analyses and hierarchical multiple regression analyses generally upheld these hypotheses. Our findings support current literature of the role of verbal working memory in reading comprehension found in English. The results, however, suggest differential role of the constructs and the tasks in reading comprehension and provide some answers for comprehension impairment in Chinese students.  相似文献

The purpose of this research is to investigate the factors that affect undergraduates' behavioral intention to use digital library among the private universities in Malaysia. The target respondents are undergraduates from Malaysian private universities. Questionnaires were distributed among 500 undergraduates through either online or face-to-face method. Reliability test, normality test, Pearson Correlation Coefficient analysis, and Multiple Linear Regression (MLR) were carried out for data analysis. Performance expectancy, social influence, facilitating conditions, hedonic motivation, habit, and information quality had a positive and significant association with behavioral intention to adopt a digital library except for effort expectancy. This research successfully reinforced that the inspiration to ameliorate Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2) by synthesis of Information Systems Success Model (ISSM). This proposed framework with a combination of ISSM and UTAUT 2 has enhanced the fitness of UTAUT 2. Universities that have yet to implement digital library can comprehend undergraduates' needs better by considering all the significant factors to develop a digital library. The universities with the digital library may also notice the important features of the existing digital library that should be maintained and upgraded constantly so that they can fulfil undergraduates' requirements.  相似文献

Relatively little work has focused on inclusive education in Singapore. This study examines the experiences and perceptions of parents whose children with disabilities are attending mainstream secondary schools in Singapore. Data was drawn from interviews with 13 parents of children with mild disabilities. Our findings reveal that parental perspective on inclusive education in Singapore is not only about classroom support but also reflects a deeper concern about whether their children with disabilities will emerge from school as contributing individuals in society. While parents strive to effectively include their children with disabilities in mainstream classrooms, there were dichotomies in their (1) understanding of disabilities, (2) expectations of school support, and (3) expectations for their child with disabilities. Given that academic and social prowess is a critical prerequisite to have a shot at entering the meritocratic Singapore society, the tension parents experience is to gauge a reasonable amount of pressure to exert on their children, the school and themselves as they assert their children's educational entitlements within an imperfect but evolving state of inclusion.  相似文献
