Conceptualizing two-variable disturbances preventing good model fit in confirmatory factor analysis as item-level method effects instead of correlated residuals avoids violating the principle that residual variation is unique for each item. The possibility of representing such a disturbance by a method factor of a bifactor measurement model was…

This research aims to compare the ability and item parameter estimations of Item Response Theory according to Maximum likelihood and Bayesian approaches in different Monte Carlo simulation conditions. For this purpose, depending on the changes in the priori distribution type, sample size, test length, and logistics model, the ability and item…

This article presents an updated meta-analysis of survey experiments comparing the performance of the item count technique (ICT) and the direct questioning method. After synthesizing 246 effect sizes from 54 studies, we find that the probability that a sensitive item will be selected is 0.089 higher when using ICT compared to direct questioning.…

This article describes the development of a new questionnaire for assessing L2 learners' language attitudes. Drawing on theoretical work in the fields of social psychology and applied linguistics, the author reviewed the concept of (language) attitudes and contrasted them with the concept of (language) motivation. This thorough literature review,…

Replications and robustness checks are key elements of the scientific method and a staple in many disciplines. However, leading journals in developmental psychology rarely include explicit replications of prior research conducted by different investigators, and few require authors to establish in their articles or online appendices that their key…

The public understanding of science is a term now considered somewhat narrow and carrying connotations of a "deficit model" of the public. Since the late 1980s, however, regular public surveys have been conducted to find out what facts about science the public knows. These include such questions as whether the Earth goes round the Sun,…

We are grateful to the commentators for providing many stimulating and valuable observations. The main point of our article was to call attention to the overestimation of individual differences correlations in a subset of neuroimaging papers. To structure our discussion of these comments, we list the main points from our paper, note where…

The aim of the present contribution is to investigate similarities and differences of strengths in science competences between countries, based on TIMSS 2003 data. Analyses are based on systematic investigation of patterns of p values for individual science items. Hierarchical cluster analysis was applied to establish meaningful groups of…

Argues that, in determining if a standardized test task and a classroom performance task are the same, educators should carefully analyze the tasks in terms of the input modality (stimulus) and the output modality (response). (FL)

The study of the structure of research articles has developed into a significant field of research. The original research focus on texts produced by English academics has been expanded over the years to allow for the investigation of the structure of texts written by academics publishing in various other languages. The ongoing discussion between…

The No Child Left Behind Act has brought great attention to the high school graduation rate as one of the mandatory accountability measures for public school systems. However, there is no consensus on how to calculate the high school graduation rate given the lack of longitudinal databases that track individual students. This study reviews…
