Estimating Population Characteristics From Sparse Matrix Samples of Item Responses

The multiple-matrix item sampling designs that provide information about population characteristics most efficiently administer too few responses to students to estimate their proficiencies individually. Marginal estimation procedures, which estimate population characteristics directly from item responses, must be employed to realize the benefits of such a sampling design. Numerical approximations of the appropriate marginal estimation procedures for a broad variety of analyses can be obtained by constructing, from the results of a comprehensive extensive marginal solution, files of plausible values of student proficiencies. This article develops the concepts behind plausible values in a simplified setting, sketches their use in the National Assessment of Educational Progress (NAEP), and illustrates the approach with data from the Scholastic Aptitude Test (SA T).     

The use of modern standard and spoken Arabic in mathematics lessons: the case of a diglossic language / El uso del árabe estándar moderno y del árabe hablado en las clases de matemáticas: el caso de una lengua diglósica

Abstract

Researchers have shown an increased interest in the way teachers use their knowledge about language (KAL) to enhance student understanding and learning. This qualitative case study investigated first- and second-grade teachers’ use of KAL in Arabic. We investigated the linguistic transitions from standard Arabic to spoken Arabic made by the teachers during mathematics lessons. The results suggested that Arab-speaking mathematics teachers were aware of the gap between home language (Spoken Arabic) and school language (Modern Standard Arabic) and used linguistic transition as a teaching strategy to develop academic thinking and behaviour among their students. The results suggested that Arab teachers built a non-formal bilingual education programme where the two languages were used to teach mathematics. Despite the requirement to use Modern Standard Arabic, participants bridged the gap between the languages, which suggests an inherent understanding that ‘language and identity are ultimately inseparable’.     

Number sense growth in kindergarten: a longitudinal investigation of children at risk for mathematics difficulties

Number sense development of 411 middle- and low-income kindergartners (mean age 5.8 years) was examined over 4 time points while controlling for gender, age, and reading skill. Although low-income children performed significantly worse than middle-income children at the end of kindergarten on all tasks, both groups progressed at about the same rate. An exception was story problems, on which the low-income group achieved at a slower rate; both income groups made comparable progress when the same problems were presented nonverbally with visual referents. Holding other predictors constant, there were small but reliable gender effects favoring boys on overall number sense performance as well as on nonverbal calculation. Using growth mixture modeling, 3 classes of growth trajectories in number sense emerged.     

Lexical ambiguity: making a case against spread

We argue for decreasing the use of the word spread when describing the statistical idea of dispersion or variability in introductory statistics courses. In addition, we argue for increasing the use of the word variability as a replacement for spread.
