The purpose of the study was to examine the efficacy of a 4-week dialogic reading intervention with rural Bangladeshi preschoolers with the intention of increasing their expressive vocabulary. Eighty preschoolers randomly selected from five preschools participated in the 4-week program. Their expressive vocabulary, measured in terms of definitions, was tested on 170 challenging words before and after the program and compared with that of control children who participated in the regular language program. Both groups were read in Bangla eight children's storybooks with illustrations, but the dialogic reading teacher was given a set of “wh” and definitional questions to enhance children's verbal participation. The mean vocabulary scores of dialogic program children increased from 26% to 54% whereas the control children remained at the same level. Results are discussed in terms of the successful application of dialogic reading to low-resource preschools. 相似文献

SPECIAL EDUCATION in Bangladesh reflects the overall educational problems faced by the nation. While some government programs for children with sensory disabilities are provided, most special education is supported by non‐government organizations. Though planning for improved special education has occurred, implementation has been restricted by economic constraints. 相似文献

Reflecting through the Indian experiences, a brief attempt is made to explore how disability as a noun takes shape in popular common sense “call names” (adjectives) and how does the popular common sense legitimise and normalise the oppressive language and the oppressed reality of the persons with disabilities? In the Indian context, the contempt for persons with disabilities is writ large in the language used to address them. However, to be conscious of this contempt, one needs to be conscious of the hegemonic nature of the popular common sense which normalises an oppressive reality as a natural social reality. The discussion on disability and popular common sense in India through the framework of “noun vs. adjective” might be helpful in gauging the challenges to the disability rights movement and the socio-cultural specificities to be reckon with for any meaningful intervention in the field of disability. 相似文献

A randomized evaluation of a 9-month comprehensive math program for preprimary Bangladeshi school children addressed skills such as numbers, measurement, shapes, patterns, and space. Nine schools were randomly selected for the Intervention group and nine for the Control group, with 12 children randomly selected from each to participate in testing. Pre- and posttested scores on each unit's skills and a cumulative test at the end were subjected to analyses of covariance. Intervention children doubled their scores on almost all tests while control children increased only slightly. Reasons for the program's effectiveness were discussed. 相似文献

In this quasi-experimental study, we describe the effect of showing dissection videos on first-year medical students' performance in terms of test scores during a gross anatomy course. We also surveyed students' perception regarding the showing of dissection videos. Two hundred eighty-seven first-year medical students at Rawalpindi Medical College in Pakistan, divided into two groups, dissected one limb in first term and switched over to the other limb in the second term. During the second term, instruction was supplemented by dissection videos. Second-term anatomy examination marks were compared with first-term scores and with results from first-year medical students in previous years. Multiple linear regression analysis was performed, with term scores (continuous, 0-200) as the dependent variable. Students shown dissection videos scored 1.26 marks higher than those not shown. The relationship was not statistically significant (95% CI: -1.11, 3.70; P = 0.314). Ninety-three percent of students favored regular inclusion of dissection videos in curriculum, and 50% termed it the best source for learning gross anatomy. Seventy-six percent of students did not perform regular cadaver dissection. The most frequent reason cited for not performing regular dissection was high student-cadaver ratio. Dissection videos did not improve performance on final examination scores; however, students favored their use. 相似文献

In wind power system, low frequency oscillations are observed due to imbalance between mechanical input and electrical output. Hence, variable susceptance controllers are being adopted to mitigate these oscillations. However, improper modulation of control parameters also leads to system instability. Therefore, we propose an optimization methodology for mitigating low frequency oscillations in wind power generation system. To visualize our methodology, we use a lead-lag type variable susceptance controller for fixed speed induction generator (FSIG) based wind generation system. Then, we optimize gain and time constants of lead-lag controller using three optimization algorithms: particle swarm optimization (PSO), genetic algorithm (GA), and flower pollination algorithm (FPA). Later, we perform non-linear time domain simulation and quantitative analysis to find average fitness, standard deviation, run time, and iteration number for these optimization algorithms. Moreover, non-parametric statistical analysis, such as Kolmogorov–Smirnov and Wilcoxon signed-rank tests are employed for identifying statistically significant differences among these algorithms. 相似文献

This essay review discusses the report of TheTask Force on Higher Education and Society(TFHES), convened in 1998 by the World Bank butindependently financed and staffed incollaboration with UNESCO and severalfoundations. Peril and Promise marks anhistoric turning point in the framework forpostsecondary educational planning. Rate-of-return analysis has been de-emphasized,while promotion of the public interest hasmoved front and center. The report of theTFHES, published in 2000 by the World Bank, hasreceived deserved attention in some parts ofthe world and has even developed an associatedwebsite (http://www.tfhe.net). As we explainbelow, the framework advocated by the TFHES isalready being used in official policy documentsof the World Bank, whose position will surelymultiply the influence of the Task Forcethrough its effect on other development banksas well as on programs of bilateral nationalassistance. And yet, despite its seminalimportance, the TFHES report has yet to befully appreciated by many researchers of highereducation. With this essay review, we hope tobroaden the discussion of the Task Force, and to offer a preliminary assessment of its impactin the 2002 World Bank policy document, and toconnect its arguments to questions that arecentral in the scholarly literature of ourfield. 相似文献
