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

This 10th article in the Performance Technologist's Toolbox series describes the data collection method of focus groups. Several variations in structure and facilitation techniques are summarized and common misconceptions are explained. Multiple applications of focus groups in performance technology are illustrated with examples. The advantages and disadvantages of using focus groups are then reviewed. The article concludes with guidelines for planning and conducting effective focus groups. 相似文献

Over time, researchers have acknowledged the importance of understanding the users’ strategies in the design of search systems. However, when involving users in the comparison of search systems, methodological challenges still exist as researchers are pondering on how to handle the variability that human participants bring to the comparisons. This paper present methods for controlling the complexity of user-centered evaluations of search user interfaces through within-subjects designs, balanced task sets, time limitations, pre-formulated queries, cached result pages, and through limiting the users’ access to result documents. Additionally, we will present our experiences in using three measures – search speed, qualified search speed, and immediate accuracy – to facilitate the comparison of different search systems over studies. 相似文献

This study examines the perceptions which teachers, head teachers and parents have of the participation of parents in the running of primary schools. While participation has been widely advocated (in North America, Europe and Africa), it appears that there are still tensions between the school and the family. The study shows that parents who are members of school councils state that they favour participation while teachers express some doubts on the positive aspects. Headteachers are more convinced, however. A number of variables help to differentiate the results, such as environment (rural, semi-urban or urban), and the sub-group to which the respondents belong (parents who are members or non-members of school councils, and teachers of different grades). The discussion considers the need for dialogue and consideration of each person's position in the interest of creating conditions favourable to children's development. 相似文献

The use of computer games as an educational tool: identification of appropriate game types and game elements 总被引:1,自引:0,他引:1

Playing games is an important part of our social and mental development. This research was initiated to identify the game type most suitable to our teaching environment and to identify game elements that students found interesting or useful within the different game types. A group of twenty students played four commercial games (SimIsle, Red Alert, Zork Nemesis and Duke Nukem 3D). Results suggest that students prefer 3D-adventure (Zork Nemesis) and strategy (Red Alert) games to the other types ("shoot-em-up", simulation) with Zork Nemesis ranked as the best. Students rated game elements such as logic, memory, visualisation and problem solving as the most important game elements. Such elements are integral to adventure games and are also required during the learning process. We present a model that links pedagogical issues with game elements. The game space contains a number of components, each encapsulates specific abstract or concrete interfaces. Understanding the relationship between educational needs and game elements will allow us to develop educational games that include visualisation and problem solving skills. Such tools could provide sufficient stimulation to engage learners in knowledge discovery, while at the same time developing new skills. 相似文献

The present study investigated the role of teacher-rated likeability as a mediator of the relation between low academic competence and depressive symptoms in elementary-aged children. Analyses focused on a sample of children at risk for child maltreatment living in Hawaii (n = 380). Structural equation modeling supported the hypothesized negative relations between academic competence in first grade and depressive symptoms in third grade controlling for correlated constructs (e.g., baseline social avoidance, parenting stress, externalizing problems, and internalizing symptoms). Teacher-rated likeability in second grade negatively mediated the effect of academic competence on depressive symptoms. Implications for understanding the role of early academic skill deficits and social judgments on risk for depressive symptoms as well as recommendations for interventions and prevention strategies are discussed. 相似文献

In this article, we propose four modifications to the standard Triple Helix innovation model, which consists of the three
strands: university, government, industry. First, in view of recent economic, cultural, organizational and ideological changes
in many countries, it is now important to introduce a fourth strand to the standard model, namely society. Second, we observe
that strands occur in doublets which we refer to as binomials. Examples of doublets include university/society, university/industry,
industry/society, etc. Third, the binomials are organized in a hierarchic mode; for example in the university/society binomial,
university may be dominant and the society secondary. The hierarchy arrangement proves decisive. Fourth, Helix-driven innovation
processes take the form of temporary segmented phases. Using the case study of Dip-Pen nanolithography, we identify four phases
where each phase is characterised by specific binomials accompanied by a hierarchy: academic instrument research (university/society);
from instrument to tool; company start-up (university/industry); the mature firm and commercialization (industry/society);
confirming the societal strand “nanofication”(society/industry). The government strand operates as a recessive component
in phases one and four. 相似文献
