Background: Gaining insight into sleep-wake patterns of persons with intellectual disabilities is commonly done using wrist actigraphy. For some people, contactless alternatives are needed. This study compares a contactless bed sensor with wrist actigraphy to monitor sleep-wake patterns of people with moderate to profound intellectual…

To ensure validity in survey research, it is imperative that we properly educate doctoral students on best practices in data quality procedures. A 14-year analysis of 679 studies in the AIS "Basket of 8" journals noted undercommunication in the most pertinent procedures, consistent across journals and time. Given recent calls for…

This research examines what practitioners in vocational education and training (VET) organisations and external auditors judge to be the key issues in the current and future use of e-assessment. Applying the framework of legitimacy theory, the study examined the tensions around the use and growth of e-assessment in training organisations, and…

Student evaluations of teaching are ubiquitous and impactful on the careers of college teachers. However, there is limited empirical research documenting the accuracy of people's efforts in interpreting teaching evaluations. The current research consisted of three studies documenting the effect of small mean differences in teaching…

The purpose of the research paper was to investigate the effect of eclectic learning approach on the academic achievement and retention of students in English at elementary level. A sample of forty students of 8th grade randomly selected from Government Boys High School Khurram District Karak was used. It was an experimental study and that's why…

In cross-cultural child development research there is often a need to translate instruments and instructions to languages other than English. Typically, the translation process focuses on ensuring linguistic equivalence. However, establishment of linguistic equivalence through translation techniques is often not sufficient to guard against…

In this case study, based on the reported rediscovery of the Ivory-billed Woodpecker in April 2005, students examine a real-world example of the scientific process and explore the practical implications of their conclusions. The case tells the story of Brad Murky, a student and research assistant who must decide whether the available evidence is…

Examines national Current Population Survey data to indicate the impact of sample size on the standard error of subpopulations in the sample and to show how these errors can influence policy conclusions. Examines the unemployment rate cross-sectionally for 11 states to demonstrate that the monthly unemployment rate should not be used to make fine…

Several general correlation patterns are shown which give exact F tests in an analysis of variance (ANOVA) procedure. They are the most general correlation patterns one can assume in a one-way and two-way layout and still have the F tests be valid. (Author/BW)

Using the split-middle methods of trend estimation, evaluates the accuracy of interpretation of single subject data by comparing raters' visual analysis of behavior change with statistical determination of behavior change. Results indicate visual analysis accuracy was less than chance. Rater and student characteristics largely did not affect the…

Bias due to attrition of respondents poses a threat to the internal and external validity of research findings. Discusses methods of detecting attrition bias in longitudinal family research, and presents Heckman's procedure to correct attrition bias. Data from the University of California Longitudinal Study of Generations are used to illustrate…

When comparing the DACUM (Developing a Curriculum) and curriculum conference methods of curriculum development, one finds that the product goals of the two methods differ but the process goals are similar. Both seek to generate information from a select group on which to base curriculum development, but the end product of DACUM is a chart that…

Paralleling the interest among researchers in naturalistic inquiry is a resurgence in action research, and particularly in research which involves the collaboration of researchers and research subjects. This paper locates the negotiation of research outcomes between researcher and subject on a continuum, with the separation of researcher and…

Evaluates the methodological adequacy of 37 studies of reading comprehension strategy instruction according to criteria of both internal and external validity. Finds many strengths, but identifies six important weaknesses. Suggests guidelines for planning future studies, and urges comprehension researchers to pay more attention to methodological…

Synthesizes findings from 36 studies that validated the Dunn and Dunn Model of Learning-Style Preferences. Questions are raised regarding the validity of the model, the nature of the literature base, the interpretation of the meta-analytic findings, and the conclusions. The article concludes that the model has not been adequately validated.…
