This paper examines a procedure measuring student competencies in numeracy using school-based assessments, and demonstrates how the procedure informs the school system on quality improvement. The sample consisted of 7648 students, attending three different types of urban schools including government, formal private and low cost private in poor informal settlements in Kenya. The numeracy tool measures six curriculum outcome areas. Each outcome area is defined by 2–11 measured items based on the emphasis given to an area in the curriculum. Within each of the outcome areas, items are also hypothesised to measure categories of the cognitive domain of learning. Using the Rasch, we examine the item difficulties, person location and differential item functioning. The paper provides important implications to provision of evidence to inform teaching in poor urban informal settlements in Kenya and this can also be replicated in other sub-Saharan African countries.

This article reports two studies exploring the academic procrastination of 456 undergraduates. Study 1 explores the relationships among academic procrastination, self-regulation, academic self-efficacy, self-esteem, and self-efficacy for self-regulation. Results reveal that although other self-variables are related to procrastination, self-efficacy for self-regulation is most predictive of procrastination tendencies. Study 2 examines academic and motivation characteristics of “negative procrastinators,” the undergraduates who are most adversely influenced by procrastination. The 25% of 195 participants in Study 2 who were classified as negative procrastinators had significantly lower GPAs, higher levels of daily and task procrastination, lower predicted and actual class grades, and lower self-efficacy for self-regulation. After controlling for GPA, daily procrastination and self-efficacy for self-regulation significantly predicted the negative impact of procrastination. The article concludes with a discussion of the importance that self-efficacy for self-regulation holds for procrastination research, and with suggestions for practitioners who work with students who are adversely affected by procrastination.  相似文献

The extent to which cognitive development and abilities are dependent on language remains controversial. In this study, the analogical reasoning skills of deaf and hard of hearing children are explored. Two groups of children (deaf and hard of hearing children with either cochlear implants or hearing aids and hearing children) completed tests of verbal and spatial analogical reasoning. Their vocabulary and grammar skills were also assessed to provide a measure of language attainment. Results indicated significant differences between the deaf and hard of hearing children (regardless of type of hearing device) and their hearing peers on vocabulary, grammar, and verbal reasoning tests. Regression analyses revealed that in the group of deaf and hard of hearing children, but not in the hearing group, the language measures were significant predictors of verbal analogical reasoning, when age and spatial analogical reasoning ability were controlled for. The implications of these findings are discussed.  相似文献

Measurements are presented of drag and lift on new tennis balls in flight. Two video cameras were used to measure the velocity and height of the balls at two positions separated horizontally by 6.4 m. The balls were fired from a ball launcher at speeds between 15 and 30 m/s and with topspin or backspin at rates up to 2,500 rpm. Significant shot-to-shot variations were found in both the drag and lift coefficients. The average drag coefficient was 0.507 ± 0.024, independent of ball speed or spin, and lower than the value usually observed in wind tunnel experiments. The lift coefficient increased with ball spin, on average, but significant lift was observed even at very low spin. The latter effect can be attributed to a side force arising from asymmetries in the ball surface, analogous to the side force responsible for the erratic path of a knuckleball in baseball.  相似文献

Picture books can influence how children perceive those from backgrounds and cultures different from their own. Studies have been conducted examining how the text of children’s literature portrays multicultural characters or characters with disabilities. However, few have looked specifically at the portrayal of characters through illustrations, despite growing understanding of the importance that illustrations play in text comprehension. Fewer still have analyzed children’s literature for depictions of deaf characters and characteristics of Deaf culture. One recent study examined children’s picture books for portrayals of deaf individuals in the text; however, examining illustrations may provide additional information for both hearing and d/Deaf (For the purpose of this paper, capital “D” Deaf refers to people who are recognized part of the Deaf community; “d” deaf refers to the inability to hear or people unable to hear; d/D includes both populations.) readers about deafness and the Deaf population. In addition, while illustrations are important for all young readers, they may be particularly important for d/Deaf readers who are by nature visual learners. Therefore, the purpose of this study was to conduct a content analysis of illustrations in 20 picture books targeted to ages 4 to 8?years for messages linked to pathological and cultural models of deafness. In addition, results were compared to previous analyses of the text in the picture books. Results indicated that the illustrations do not represent deaf characters from a cultural perspective. Instead, similar to the text, illustrations present deaf characters more frequently as having a pathological condition or disability, that should be fixed through medical interventions in order to fit into a hearing world.  相似文献

This longitudinal investigation examined word decoding and reading comprehension measures from first grade through sixth grade for a sample of Spanish-speaking English language learners (ELLs). The sample included 261 children (average age of 7.2 years; 120 boys; 141 girls) at the initial data collection in first grade. The ELLs’ word decoding and reading comprehension scores showed quadratic growth over the course of the study. The sample’s reading comprehension, but not their word decoding, began to fall behind the normative sample starting in the third grade. Phonological awareness, rapid automatic naming (RAN), and oral language measures were used as predictors and correlated with growth rates in a manner consistent with past research.  相似文献

Researchers suggest an increase in self‐harm among men. Specifically, college‐age men appear to be at risk for self‐harming behaviors, and counselors often overlook these behaviors in treatment. In this article, the authors describe the issue of self‐harm and illustrate the use of dialectical behavior therapy (DBT; Linehan, 2014 ) with male college students. The authors use a case study to illustrate the use of a modified form of DBT with a male college student who self‐harmed. Limitations of this approach and implications for college counselors are also addressed.  相似文献

One hundred and twelve children, 56 toddlers and 56 preschoolers, were observed in their family child care settings to determine whether toddlers cared for in settings that also included preschoolers were, relative to the preschoolers, receiving more or less high-quality care and/or whether their functioning at child care appeared to be more or less dependent on aspects of the care providers’ interactions with the children. Quality of care was analyzed along two dimensions: sensitive/supportive care and structured care. Four indices of child functioning at child care were examined: integration in social activities, attention, positive mood, and angry/aggressive behavior. Results indicate that toddlers received less sensitive, supportive care than preschoolers in these mixed-age settings and toddlers were less socially integrated and less engaged in activities in the child care setting. Preschoolers displayed increased levels of angry/aggressive behavior relative to toddlers. In addition, associations of care provider behaviors and child functioning were larger for toddlers than preschoolers, suggesting that toddlers were more dependent on caregiver support for more successful functioning in these family child care settings. For both toddlers and preschoolers, care provider behavior and child functioning was generally poorer in settings with more children.  相似文献

The focus of this article is on scale score transformations that can be used to stabilize conditional standard errors of measurement (CSEMs). Three transformations for stabilizing the estimated CSEMs are reviewed, including the traditional arcsine transformation, a recently developed general variance stabilization transformation, and a new method proposed in this article involving cubic transformations. Two examples are provided and the three scale score transformations are compared in terms of how well they stabilize CSEMs estimated from compound binomial and item response theory (IRT) models. Advantages of the cubic transformation are demonstrated with respect to CSEM stabilization and other scaling criteria (e.g., scale score distributions that are more symmetric).  相似文献

In recent years, there has been a renewed interest in the dichotomy of vocational education versus general education. This is more so as political pronouncements in many countries across the globe have taken on knowledge and skills as the key aim of the desire to improve access to education at all levels. Nowhere is this debate more tested, fiercely debated and gained controversy as in Africa. However, given recent developments in which knowledge and skills have become more acceptable terms in economically more developed nations, in which both are seen to go hand in hand, what is happening in Africa where development is highly sought but has proven to be more elusive? This has brought back to the forefront one of the dilemmas which has pre-occupied many African countries for a long time: whether to concentrate investment in general education or in vocational education. In this paper, I reflect on current trends and issues in TVET in Africa.  相似文献
