Social studies teachers rely too heavily on textbooks which contain minimal problem solving or other high level cognitive tasks. This finding raises serious questions about the capacity of a social studies curriculum meeting the goals for a program for the gifted.  相似文献

The study presents the process of differentiated instruction, its implementation, and impact on second graders in a Lebanese school It analyses how writing instruction has been differentiated through implementing the writing workshop to help students demonstrate improved writing skills. It examines the effects of second graders' participation in the writing workshop and discusses the factors that enabled students to develop their writing skills. Data collection includes pre- and post-writing samples, reflective journal and checklists during individual conferences. Findings show that students' writing skills improved as reflected in their progression of text, expansion of ideas, and development in conventional writing.  相似文献

Problem-based learning (PBL) is one among several approaches to active learning. Being a teacher in a PBL environment can, however, be a challenge because of the need to support students’ learning within a broad ‘landscape of learning’. In this article we will analyse the landscape of learning by use of the study activity model (SAM) developed by the Danish University Colleges, with the aim of investigating to which extent this may lead to explication and clarification concerning the challenges faced by teachers in a PBL environment. In the case study, the SAM is applied to the first semester of an engineering programme at Aalborg University, a university setting where the PBL approach to teaching and learning is dominant. The results of the analysis are presented and discussed, and the conclusion is that the model, in spite of some shortcomings, is useful in clarifying the role of the teacher in a PBL environment.  相似文献

In foregrounding how girls use their bodies when negotiating subjectivities as adolescents, this paper explores possible ways of doing, being and becoming an adolescent girl in urban, multicultural school contexts. Drawing on interview material generated through a longitudinal qualitative study of children's social transitions between childhood and adolescence, the paper more specifically examines how girls constitute subjectivities through bodily practices which position them according to dominant discourses of hetero‐femininity. The paper goes on to argue that the way in which girls negotiate these discourses through practices on and with their bodies has a significant impact on how they subsequently experience their social transition between childhood and adolescence.  相似文献

The expression of the self through multimodal texts is a central theme in education. While it has been suggested that new technologies act as important mediators in the relationship between texts and subjectivity, the mechanisms underlying such mediation has been a neglected topic of research. This paper considers the theoretical assumptions upon which speculation so far has been based and explores the methodologies that are best suited to investigating further the relationships between text, self and technology.  相似文献

Mucopolysaccharidosis are a group of rare metabolic disorders of the lysosomal storage disease family caused by the absence or malfunctioning of lysosomal enzymes responsible for their breakdown. It encompasses disorders in which undegraded or partly degraded glycosaminoglycans accumulate in the lysosomes of many tissues owing to a deficiency of specific lysosomal enzymes. Here we report a case of a 7 years old child displaying the symptoms of Morquio’s disease (Mucopolysaccharidosis type IV). Urine screening tests were performed which gave contrasting results.  相似文献

Ethnic/racial discrimination is associated with negative psychosocial outcomes, and this study considered sleep disturbance as a mediating pathway. Employing a combination of daily diary and biannual surveys, multilevel structural equation models estimated the indirect effects of sleep/wake concerns on negative, anxious, and positive mood, rumination, and somatic symptoms. In a sample of 350 urban Asian (74% Chinese, 8% Korean, 4% Indian, 1% Filipinx, 1% Vietnamese, and 12% other), Black, and Latinx (25% Dominican, 24% South American, 22% Mexican, 15% Puerto Rican, 5% Central American, and 9% other) youth (M = 14.27 years, 69% female, 77% U.S. born, 76% monoethnic/racial, data collected from 2015 to 2018), there was evidence for sleep disturbances mediating the impact of ethnic/racial discrimination on adjustment. Nighttime disturbance, daytime dysfunction, and daytime sleepiness evidenced partial or full mediation for daily- and person-level outcomes (υ = 0.1%–17.9%). Reciprocal associations between sleep disturbances and negative mood and rumination were also observed.  相似文献

The present study investigates primary school students’ self-regulated learning (SRL) process by exploring the sequence in which SRL activities are conducted during learning. The aims of this study are twofold: investigating the presence of the theoretically hypothesized cyclical nature in students’ SRL process, as well as potential differences herein for high, average, and low achievers. Think-aloud data of 104 upper primary school students were analysed by means of process mining analysis. The results indicate that students commonly adopt a cyclical approach to learning by implementing preparatory, performance, and appraisal activities during learning. However, the results indicate clear differences in the quality of students’ SRL process. High achievers, compared to low and average achievers, show a more strategic and adaptive approach to learning during all phases of their learning process. They more strategically and effectively orient on and plan assignments, combine different cognitive strategies, and adopt self-evaluation to regulate their learning process.

Race and socioeconomic status (SES) moderated the link between children's sleep and cognitive functioning. One hundred and sixty-six 8- to 9-year-old African and European American children varying in SES participated. Sleep measures were actigraphy, sleep diaries, and self-report; cognitive measures were from the Woodcock-Johnson III and reaction time tasks. Children had similar performance when sleep was more optimal, but after controlling for SES, African American children had lower performance with sleep disruptions. Children from lower and higher SES had similar performance with better sleep quality and less variability in sleep schedules, but when sleep was more disrupted, higher SES children had better performance. Examination of environmental variables associated with race and SES that may underlie these effects may lead to directions for interventions to improve cognitive performance.  相似文献

Abstract

An evaluation was conducted to measure the impact of a curriculum implementation through the Jordan Water Conservation Education Project funded by USAID. This study examined the effect of recommending water conservation at the household level and the impact of using interactive teaching methods to promote conservation behaviors among students and their families. The evaluation used a postintervention design with random selection of participants. Comparisons were made among 671 students (424 experimental, 247 control) belonging to high school eco-clubs in central Jordan. Most students were girls in rural settings. The experimental group consisted of students whose teachers implemented an interactive curriculum and promoted household water-conservation behaviors. Teachers of students in the control group did not participate in the curriculum implementation, but those students were exposed to lectures about biodiversity issues. The results indicate that students who were exposed to the new curriculum demonstrated a higher level of knowledge about water conservation and performed recommended behaviors more often than students in the control group.  相似文献
