Most social communication tests used to measure change in young children with autism spectrum disorder have not undergone rigorous psychometric evaluation. Notably, and most relevant to the early intervention literature, there is little information on the sensitivity of these measures to change over time, despite their frequent use. Further, most…

Developmental assessment scales are important tools for determining developmental delays and planning preventive interventions. One broad assessment scale used to evaluate child development is the Battelle Developmental Inventories (BDIs). The BDI-2 has a standardized version in English with good psychometric properties and a translated version in…

Structural equation modeling (SEM) is one of the most popular multivariate statistical techniques in Turkish educational research. This study elaborates the SEM procedures employed by 75 educational research articles which were published from 2010 to 2015 in Turkey. After documenting and coding 75 academic papers, categorical frequencies and…

In this commentary, we offer a set of visual tools that can assist education researchers, especially those in the field of mathematics, in developing cohesiveness from a mixed methods perspective, commencing at a study's research questions and literature review, through its data collection and analysis, and finally to its results. This expounds…

In mixed methods research (MMR), integrating the quantitative and the qualitative components of a study is assumed to result in additional knowledge (or "yield"). This narrative review examines the extent to which MMR is used in the field of childhood trauma and provides directions for improving mixed methods studies in this field. A…

Research and scholarship into educational effectiveness research (EER) is comprehensively reviewed from the UK, The Netherlands, the US, Cyprus, Belgium, Sweden, France, Germany, New Zealand, Australia, and other societies, dating from the field's origins in the 1970s. Issues include its history, methodological and theoretical advances, scientific…

Foster parents have special needs which must be addressed to retain them in the child welfare system. Several of these needs may be addressed within their foster parent training experience; however, little research is available to determine the effectiveness of these training programs. What little research is available is fraught with…

Introduces some methodological procedures from psychology that may be useful in curriculum research. Although the notion of construct validity lends itself well to an area as complex as curriculum, the author experienced difficulty finding studies that utilized a multimethod, multitrait matrix approach.

Reviewed 149 studies which measured counselor or therapist competencies and examined them for evidence of the reliability and validity associated with the assessment instruments. Only 43 percent of the measurements included reliability data computed at the time they were used, and only 12 percent were accompanied by evidence of their validity.…

Discusses methodological issues in paper-and-pencil measuring instruments applicable to the assessment of attitudes toward women, men and a variety of gender-related issues. Commonly used questionnaire formats are critiqued and the limitations of heterogeneous scales explored. Presents recommendations for the construction of scales that predict…

In this selective look at research on test-taking strategies over the last 25 years, brief mention is made of the beginnings of test-taker strategy research, and then important developments in its evolution to the present are discussed, focusing on conceptual frameworks for classifying strategies, first and second language-related strategies,…

Two methodological problems often arising in dyslexia research are considered. The first problem concerns the validity of experimental measures and the related problem of interpreting null results. The second problem involves the effects of sampling from a disabled population if the disorder under investigation has multiple unknown origins.…

A review of studies on effective principals reveals that a number of methodological problems have prevented the accumulation of findings adequate to producing well developed models of instructional leadership and its effects on school outcomes. Problems of measurement and research design in the existing literature are reviewed and suggestions for…

This paper reviews seven research studies on the subject of readability. The first study reviewed is itself an extensive review of 30 readability formulas described by George A. Klare. Of these, five formulas considered to be interesting, unusual, or classic on the basis of high validity, simplicity or complexity, common or uncommon variables, and…

Methods used in validating construct interpretations of self-concept measurements are briefly reviewed, and relevant papers presented in this special issue are discussed. The strengths and limitations of each paper are outlined. Thirty bibliographical references are included. (Author/MV)
