This article features an elementary teacher who has worked with the authors for the past 10 years in research on building a classroom community and using cultural universals as the centerpiece for elementary social studies for all children. Cultural universals are basic human needs and social experiences found in all societies, past and present, and include food, shelter, clothing, transportation, communication, family living, money, childhood, government, and so on. Actions related to cultural universals are experienced by all children regardless of their cultures, socioeconomic backgrounds, achievement levels, or special needs, so teachers can connect to these experiences as bases for developing historical, geographic, political, economic, sociological, psychological, or anthropological understandings. The ultimate goal is connected knowledge about how the social system works, how and why it developed over time, how and why it varies across locations and cultures, and what all this might mean for personal, social, and civic decision making. 相似文献

In the past decade, research on learning trajectories has progressed from an agenda for research on student learning to include an agenda for research on teaching. In this paper, we use a design experiment to examine a professional development program created to support teacher learning of one learning trajectory. Using a re-interpretation of Ball and colleagues’ mathematics knowledge for teaching framework, we conducted a retrospective analysis to examine how a purposefully selected sample of three teachers used their knowledge to participate in discussions of the professional learning tasks designed to support teacher learning of the trajectory. Findings indicate that professional learning tasks focusing on pedagogical content knowledge present in learning trajectories also allow for teacher learning of subject matter knowledge; this learning is mediated by teachers’ prior mathematics knowledge for teaching. We conclude with considerations for researchers and professional developers seeking to support teachers in learning about learning trajectories. 相似文献

Recent criticisms of textbooks have included accusations of favoring breadth over depth, dry writing, lack of context, failure
to integrate minority groups, and overillustration. Social studies texts have, in addition, been criticized for meaning-less
content, unclear goals, inadequate explanation, separation of knowledge from skills, and other failings. The authors of this
article have specified other common faults. As a corrective, they suggests a return to the notion of developing curricula
as means to accomplish major goals phrased in terms of intended student outcomes, and aligning social studies instruction
with major social education goals. 相似文献

This paper explores schooling determinants in Nicaragua. Results include: (1) schooling is determined simultaneously with number of children, although simultaneous estimates do not indicate sharp ‘quantity-quality’ trade-offs. (2) Rural boys receive less schooling than rural girls, possibly because of higher opportunity costs for boys in agricultural work. (3) Family background is quite important, suggesting limited intergenerational mobility. (4) Income has permanent and transitory effects. However, women's full income does not seem particularly important. (5) Parental schooling partially represents taste and genetic effects. Thus the interpretation of schooling as representing only efficiency is misleading and may lead to important distortions in the allocation of resources and ambiguous private welfare effects. 相似文献

Effects of a reform high school mathematics curriculum on student achievement: whom does it benefit?
This study compared the effects of an integrated reform-based curriculum to a subject-specific curriculum on student learning of 19,526 high school algebra students. Using hierarchical linear modelling to account for variation in student achievement, the impact of the reform-based Core-Plus Mathematics curricular materials on student test scores is compared to the subject-specific curriculum. Findings from this study indicate that students enrolled in integrated mathematics outperformed subject-specific students on an Algebra I exam (highly aligned with content), and performed equally on an Algebra II exam (poorly aligned). High minority students in high-need schools demonstrated higher performance when they were enrolled in integrated mathematics. 相似文献

Conventional treatments of functions start by building a rule of correspondence betweenx-values andy-values, typically by creating an equation of the formy=f(x). We call this acorrespondence approach to functions. However, in our work with students we have found that acovariational appraoch is often more powerful, where students working in a problem situation first fill down a table column withx-values, typically by adding 1, then fill down ay-column through an operation they construct within the problem context. Such an approach has the benefit of emphasizing rate-of-change. It also raises the question of what it is that we want to cal rate across different functional situations. We make two initial conjectures, first that a rate can be initially understood as aunit per unit comparison and second that a unit is theinvariant relationship between a successor and its predecessor. Based on these conjectures we describe a variety of multiplicative units, then propose three ways of understanding rate of change in relation to exponential functions. Finally we argue that rate is different than ratio and that an integrated understanding of rate is built from multiple concepts. 相似文献

To monitor and evaluate the feasibility of implementing Trauma Focused-Cognitive Behavioral Therapy (TF-CBT) to address trauma and stress-related symptoms in orphans and vulnerable children (OVC) in Zambia as part of ongoing programming within a non-governmental organization (NGO). As part of ongoing programming, voluntary care-workers administered locally validated assessments to identify children who met criteria for moderate to severe trauma symptomatology. Local lay counselors implemented TF-CBT with identified families, while participating in ongoing supervision. Fifty-eight children and adolescents aged 5–18 completed the TF-CBT treatment, with pre- and post-assessments. The mean number of traumas reported by the treatment completers (N = 58) was 4.11. Post assessments showed significant reductions in severity of trauma symptoms (p < 0.0001), and severity of shame symptoms (p < 0.0001). Our results suggest that TF-CBT is a feasible treatment option in Zambia for OVC. A decrease in symptoms suggests that a controlled trial is warranted. Implementation factors monitored suggest that it is feasible to integrate and evaluate evidence-based mental health assessments and intervention into programmatic services run by an NGO in low/middle resource countries. Results also support the effectiveness of implementation strategies such as task shifting, and the Apprenticeship Model of training and supervision. 相似文献
