Since Topping published his literature review on peer assessment in 1998, the number of studies on this subject has doubled, if not tripled. However, along with this expansion, the diversity of peer assessment applications increased equally fast. Based on recent literature, this contribution focuses specifically on the diversity that has come to…

The current article reviews research published in "Assessment for Effective Intervention" during the past 3 years. A total of 57 research articles were published during that period, with a current rejection rate of approximately 78%. A close examination of the pool of articles revealed seven overarching themes: behavioral assessment tools, group…

Humphry (this issue) has written a thought-provoking piece on the interpretation of item discrimination parameters as scale units in item response theory. One of the key features of his work is the description of an item response theory (IRT) model that he calls the logistic measurement function that combines aspects of two traditions in IRT that…

Behavioral scientists have struggled with units of measurement for as long as they have struggled with measurement itself. Psychology's sole attempt at an explicit unit of measurement--the Lexile Framework for Reading (Stenner, Burdick, Sanford, & Burdick, 2006)--has been and continues to be ignored by the psychometric "cognoscenti."…

The purpose of this article is to examine the role of the unit in physics in order to clarify the role of the unit in psychometrics. Based on this examination, metrological conventions are used to formulate the relationship between discrimination and the unit of a scale in item response theory. Seminal literature in two lines of item response…

This article presents Stephen Humphry's response to the commentaries for his article "The Role of the Unit in Physics and Psychometrics." The commentaries covered a range of important considerations and implications. Given that the author fully agrees with the majority of the content, attention will be confined mainly to points that call…

This article presents the keynote address given by Katherine J. Pinch at the 2008 Annual Symposium on Experiential Education Research (SEER). Pinch discusses the importance of evaluation research and argues that the realm of evaluation is where the margins of research and practice have the potential to intersect with the greatest ease. She…

Child assessment practices in English and Korean preschools were compared by analysing data from interviews with educators, examples of child assessment, and official documents from each country. Child assessment in England was systematically implemented and characterised by several methodological and procedural strengths, whereas assessment in…

This paper is part of a series investigating the implementation of competency education. The purpose of the paper is to explore how districts and schools can redesign grading systems to best help students to excel in academics and to gain the skills that are needed to be successful in college, the community, and the workplace. In order to make the…

Offering meaningful service to the community while engaging in active learning is a pedagogical strategy that has come to be known as service-learning. Both learner and the community are mutual recipients of benefits derived from the process. The fundamental question that remains is, "How do we assess the learner in this non traditional…

This article investigates three types of stage-sequential growth mixture models in the structural equation modeling framework for the analysis of multiple-phase longitudinal data. These models can be important tools for situations in which a single-phase growth mixture model produces distorted results and can allow researchers to better understand…

There is a plethora of research on student evaluations of teaching (SETs) regarding their validity, susceptibility to bias, practical use and effective implementation. Given that there is not one study summarising all these domains of research, a comprehensive overview of SETs was conducted by combining all prior meta-analyses related to SETs.…

This article provides two illustrations of some of the factors that can influence findings from pre- and post-test research designs in evaluation studies, including regression to the mean (RTM), maturation, history and test effects. The first illustration involves a re-analysis of data from a study by Marsden (2004), in which pre-test scores are…

Surveys and benchmarks continue to grow in importance for community colleges in response to several factors. One is the press for accountability, that is, for colleges to report the outcomes of their programs and services to demonstrate their quality and prudent use of resources, primarily to external constituents and governing boards at the state…

The purpose of this article is to define and clarify the process of instructional problem-solving using assessment data within action research (AR) and Response to Intervention (RtI). Similarities between AR and RtI are defined and compared. Lastly, specific resources and examples of the instructional problem-solving process of AR within…
