Apprehending Mathematical Structure: A Case Study of Coming to Understand a Commutative Ring     

Adrian Simpson  Nada Stehlíková 《Educational Studies in Mathematics》2006,61(3):347-371

Abstract algebra courses tend to take one of two pedagogical routes: from examples of mathematics structures through definitions to general theorems, or directly from definitions to general theorems. The former route seems to be based on the implicit pedagogical intention that students will use their understanding of particular examples of an algebraic structure to get a sense of those properties which form the basis of the fundamental definitions. We will explain the transition from examples to abstract algebra as a series of shifts of attention and in this paper we will use a case study to examine the initial shift, which we will call apprehending a structure, and examine how one student came to apprehend the structure of the commutative ring Z₉₉.  相似文献   

Student Assessment of Self-Efficacy and Practice Readiness Following Simulated Instruction in an Undergraduate Social Work Program

ABSTRACT

The use of simulated instruction is a growing trend in social work education. This study examined the effectiveness of simulated instruction with undergraduate social work students. In this mixed methods study, the extent to which simulated instruction improved self-efficacy and practice readiness was assessed. Results of the study suggest that simulated instruction helps improve key practice skills and increases recognition of diversity in practice. Moreover, students self-reported increased mastery in interviewing, managing emotions, and engaging in culturally competent practice.  相似文献

Classroom age composition and the early learning of preschoolers     

Arya Ansari  Robert Pianta 《The Journal of educational research》2019,112(2):234-242

Data from 1,407 preschoolers were used to examine the implications of classroom age composition for the early learning and development of 4-year-olds in classrooms with 3- and 5-year-olds also in attendance. Results suggest that a greater number of younger classmates did not detract from 4-year-olds’ language development, literacy performance, or inhibitory control, nor did having older peers consistently facilitate learning in these domains. However, 4-year-olds who entered school with low inhibitory control and print knowledge demonstrated greater gains in both domains when attending classrooms with more same-age or older classmates than when in classrooms with more younger peers. When taken together, these results suggest that classroom age composition, in prekindergarten programs serving mostly 4-year-olds, for the most part has little consequence except for those 4-year-olds entering school with lower skill levels in key domains, in which case having older peers is of benefit.  相似文献

Phonological Awareness and Bilingual Preschoolers: Should We Teach It and, If So, How?     

Mark R. Stewart 《Early Childhood Education Journal》2004,32(1):31-37

This article briefly reviews recent research on teaching phonological awareness skills to preschoolers as well as the benefits of different types of bilingual education. A more in-depth analysis of research on cross-language transfer of phonological awareness/metalinguistic skills follows. The major recommendation resulting from this review is that the teaching of phonological awareness skills in both the home language and school language of preschoolers is the preferred intervention.  相似文献   

Supporting Early Childhood Social-Emotional Well Being: The Building Blocks for Early Learning and School Success     

Aparna?BagdiEmail author  John?Vacca 《Early Childhood Education Journal》2005,33(3):145-150

The period of early childhood sets the stage for how well children view themselves, each other, and their world. Shared positive emotional experiences between caregivers and children serve as building blocks for the development of social and emotional well-being in infants and toddlers. Incorporating the three principles of promotion, prevention, and intervention within a systems framework (child–parent–environment) will enable early childhood practitioners to foster the emotional health and well-being of all children and families, especially those individual children who are more vulnerable due to the presence of multiple risk factors. The primary intent of the authors of this paper is to discuss the importance of attending to the social and emotional well being of very young children as a primary focus of early learning and school success.  相似文献
