Standard Deviations

We examine access to effective teachers for low-income students in 26 geographically dispersed school districts over a 5-year period. We measure teacher effectiveness using a value-added model that accounts for measurement error in prior test scores and peer effects. Differences between the average value added of teachers of high- and low-income students are 0.005 standard deviations in English/language arts and 0.004 standard deviations in math. Differences between teachers of Black, Hispanic, and White students are also small. Rearranging teachers to obtain perfect equity would do little to narrow the sizable student achievement gap between low- and high-income students. We also show that a higher proportion of novice teachers in high-poverty schools contributes negligibly to differences in access to effective teachers.

Level Effect

This paper investigated the effect of teacher quality, represented by teacher level characteristics, on mathematics gain scores employing a three-level hierarchical linear model (HLM) through value-added model (VAM) approach. The analysis investigated significant predictors at student, teacher, and school levels for predicting students' gain scores and also estimated d-type effect sizes at teacher and school levels. We found the significant effects of teacher's mathematics content certification, teacher experience, and the interaction effects of mathematics content certification with student level predictors. Although school poverty significantly predicted students' gain scores, the school level effect was relatively small.

Purpose – The purpose of this paper is to explore the concept of adding value and in particular to suggest ways in which libraries can add even more value than they do so now. Design/methodology/approach – With this primarily a literature review combined with some examples of ways in which some libraries are adding value in new and interesting ways. This paper seeks to extend the work of Robert Taylor who developed a Value-Added Model. Findings – Libraries must find new ways to add value to their collections and services as competitors continue to introduce convenient services that are drawing people away from libraries. The ways in which a library might add new value have been grouped into five broad categories: community, content, context, collaboration, or co-creation and connection. Each category is discussed in some detail and examples are provided to illustrate possibilities. Originality/value – Exploring ways in which libraries can add value in the life of their customers must become a topic of conversation for librarians everywhere. The mandate to change is ever present and libraries need to introduce new and innovative services that add real value.
