Aspects of ‘relevance’ in the alignment of curriculum with educational standards

With over 60,000 US K-12 science and mathematics education standards and a rapid proliferation of Web-enabled curriculum, retrieving curriculum that aligns with the standards to which teachers must teach is a key objective for educational digital libraries. However, previous studies of such alignment use single-dimensional and binary measures of the alignment concept. As a consequence, they suffer from low inter-rater reliability (IRR), with experts agreeing about alignments only some 20–40% of the time. We present the results of an experiment in which the alignment variable was operationalized using the Saracevic model of relevance ‘clues’ taken from the everyday practice of K-12 teaching. Results show high IRR across all clues with IRR on several specific alignment dimensions significantly higher than on overall alignment. In addition, a model of overall alignment is derived and estimated. The structure and explanatory power of the model as well as the relationships between alignment clues differ significantly between alignments of curriculum found by users themselves and curriculum found by others. These results illustrate the usefulness of clue-based relevance measures for information retrieval and have important consequences for both the formulation of automated retrieval mechanisms and the construction of a gold standard or benchmark set of standard-curriculum alignments.     

Patterns of Risk and Protective Factors Among Alaska Children: Association With Maternal and Child Well-Being

This study used population-representative data to examine associations of risk and protective factor patterns among Alaska Native/American Indian (AN/AI; N = 592) and non-Native (N = 1,018) children with maternal and child outcomes at age 3 years. Among AN/AI children, a high risk/moderate protection class was associated with child developmental risk and mothers being less likely to feel comfortable asking for help or knowing where to go for parenting information compared to a low socioeconomic status/high protection class. Among non-Native children, a moderate risk/high protection class was associated with child developmental risk and mothers being less likely to feel comfortable asking for help compared to a low risk/high protection class. Results provide insight on the intersection of risk and protective factors among Alaska families.     

Revisiting the Task/Achievement Analysis of Teaching in Neo-Liberal Times

In 1975 I published an article on Gilbert Ryle's task/achievement analysis of teaching ( Marshall, 1975 ), arguing that teaching was in Ryle's sense of the distinction a task verb. Philosophers of education were appealing to a distinction between tasks and achievements in their discussions of teaching, but they were often also appealing to Ryle's work on the analysis of task and achievement verbs. Many philosophers of education misunderstood Ryle's distinction as teaching was often claimed to be a term with both an achievement sense and a task sense. In terms of Ryle's distinction a verb could not have both a task and an achievement sense.
  It will be argued that in recent (neo-liberal) discussions of education, teaching is treated more as an achievement verb than as a task verb, contrary to my original claim that teaching was a task verb. 'Teaching' then would appear to have changed its meaning. If that is so, it is a function of altered approaches to teaching (and its teaching in Teacher Education), whereby unless something of value has been added then the teaching was not successful, or appropriate.     

School quality and learning gains in rural Guatemala

I use unusually detailed data on schools, teachers and classrooms to explain student achievement growth in rural Guatemala. Several variables that have received little attention in previous studies – including the number of school days, teacher content knowledge and pedagogical methods – are robust predictors of achievement. A series of decompositions by student ethnicity and type of school shed some additional light on important questions in the Guatemalan context, and beyond. The large indigenous test score gap is not explained by differences in an extensive list of observable features of schools. The large effect for community characteristics suggests peer group effects or more general institutional differences related to services or labor markets. PRONADE community schools are associated with moderate gains vis-à-vis public schools in areas related to utilization of capacity, such as days worked. But these gains are largely offset by lower teacher capacity, which highlights the challenge of improving school quality in poor, rural areas.     

Goals or horizons—the conundrum of progression in English: or a possible way of understanding formative assessment in English

This article examines how the principles of formative assessment might be applied to the curriculum subject of English. It takes as its starting point the problematic nature of progression in the subject and suggests that it may be better to understand progression as heading towards a horizon rather than a clearly defined goal. The article argues this by exploring the potential constraints of what might be considered goal models of progression and contrasts these with the affordances offered by those approaches that view progression as towards a horizon. In particular it suggests that, in order to understand how to progress, pupils need to acquire the guild subject knowledge of their teachers by being apprenticed into the same community of interpreters. The article situates this discussion within wider concerns about how teachers scaffold and regulate the learning process for their pupils.

Benchmarking reference services: an introduction

Benchmarking is based on the common sense idea that someone else, either inside or outside of libraries, has found a better way of doing certain things and that your own library's performance can be improved by finding out how others do things and adopting the best practices you find. Benchmarking is one of the tools used for achieving continuous improvement in Total Quality Management (TQM) programs. Although benchmarking can be done on an informal basis, TQM puts considerable emphasis on formal data collection and performance measurement. Used to its full potential, benchmarking can provide a common measuring stick to evaluate process performance. This article introduces the general concept of benchmarking, linking it whenever possible to reference services in health sciences libraries. Data collection instruments that have potential application in benchmarking studies are discussed and the need to develop common measurement tools to facilitate benchmarking is emphasized.
