DISTRIBUTIVE PARTITIONING OPERATION IN MATHEMATICAL SITUATIONS INVOLVING FRACTIONAL QUANTITIES     

Soo Jin Lee  Jaehong Shin 《International Journal of Science and Mathematics Education》2015,13(2):329-355

In the present study, we describe a participating student’s (Carol’s) distributive partitioning scheme and operations along with Steffe’s and his colleagues’ studies about children’s constructions of fraction knowledge as a particular model of mathematical learning. Analysis of Carol’s mathematical behaviors indicates that an operationally common mathematical behavior (distributive partitioning operation) was revealed in various mathematical problem situations such as fraction multiplication, fraction division, and multiplicative transformation between fractional quantities. It both provides a rationale for why becoming versed in one mathematical subject could facilitate working with another mathematical subject and also implies the necessity of describing and defining students’ mathematical behaviors from an operational view of knowledge, which might lead to building foundations of a substantial cognitive map for students’ mathematical development.  相似文献

Evaluating Growth for ELL Students: Implications for Accountability Policies     

Joni M. Lakin  John W. Young 《Educational Measurement》2013,32(3):11-26

In recent years, many U.S. states have introduced growth models as part of their educational accountability systems. Although the validity of growth‐based accountability models has been evaluated for the general population, the impact of those models for English language learner (ELL) students, a growing segment of the student population, has not received sufficient attention. We evaluated three commonly used growth models: value tables or transition matrices, projection models, and student growth percentiles (SGP). The value table model identified more ELL students as on track to proficiency, but with lower accuracy for ELL students. The projection and SGP models were more accurate overall, but classified the fewest ELL students as on track and were less likely to identify ELL students who would later be proficient. We found that each model had significant trade‐offs in terms of the decisions made for ELL students. These findings should be replicated in additional state contexts and considered in the development of future growth‐based accountability policies.  相似文献   

Post-qualitative research     

Michelle D. Young 《International journal of qualitative studies in education》2013,26(6):629-660

This article maintains that all research involves crossing (i.e., researching across difference) and then explores how scholars have approached issues of cross-group feminist research. The article is divided into three major sections. The first section explores issues of women?s diversity and their meaning for cross-group feminist research. The second investigates concerns raised with regard to contradictions inherent in this type of research. The third section reviews and discusses a number of strategies feminist and other scholars of qualitative research have used to address problematic issues and contradictions involved in cross-group research.  相似文献
