Background: Event-related potentials (ERPs), which are electrophysiological neural responses time-locked to a stimulus, have become an increasingly common tool in language and communication disorders research. They can provide complementary evidence to behavioural measures as well as unique perspectives on communication disorders. ERPs have the…

TIMSS (Trends in International Mathematics and Science Study) is a long-standing international assessment of mathematics and science at the fourth and eighth grades that has been collecting trend data every four years since 1995. About 70 countries use TIMSS trend data for monitoring the effectiveness of their education systems in a global…

As pressure builds to assess students, teachers, and schools, educational practitioners and policy makers are increasingly looking toward student perception surveys as a promising means to collect high-quality, useful data. For instance, the widely cited Measures of Effective Teaching study lists student perception surveys as one of the three key…

This discussion constructs a survey data quality strategy for institutional researchers in higher education in light of total survey error theory. It starts with describing the characteristics of institutional research and identifying the gaps in literature regarding survey data quality issues in institutional research and then introduces the…

Discusses how to define a welfare spell (period on welfare) and how well surveys measure welfare spells. A look at survey and administrative data from two studies shows that a substantial amount of administrative churning occurs in administrative data. A single definition of a welfare spell does not appear applicable to all respondents. (SLD)

Several approaches to response to intervention (RTI) described in the literature could be blended into an RTI model that would be effective in the schools. An effective RTI model should employ three fundamental variables: (a) systematic data collection to identify students in need, (b) effective implementation of interventions for adequate…

Describes the Adjusted Agreement Index, a strategy for analyzing collected data from questionnaires utilizing Likert-type scales. Steps involved in using this index and its strengths and weaknesses are outlined, and a case study illustrating how it was used to summarize data on a distance education course package is presented. (MBR)

A plan was developed to improve followup study response rates by refining techniques for data collection and improving student motivation to respond to daily requests. Factors affecting response rate to followup surveys were investigated, and alternative approaches were recommended. Findings indicated that current procedures--two mailouts of…

This article reviews the basics of learning channels and how specification of stimuli can help enhance verbal behavior. This article will define learning channels and the role of the ability matrix in training verbal behavior.
