The authors examined the confidence of teachers from Germany, Hong Kong, Italy, and the United States (N = 1,375) to address civic topics with their students. The authors also used differential item functioning models to examine responses to items from the Teacher Confidence Scale of the International Association for the Evaluation of Educational…

Building on previous studies of the effects of planning on second language learners' (L2) oral narratives and writing, this research reports an investigation of the effects of vocabulary preparation prior to a listening comprehension test on L2 learners' vocabulary performance, listening comprehension, confidence levels and strategy use. The…

Results are presented from a formal evaluation of The Pennsylvania Bureau of State Park's Watershed Education (WE) curriculum developed for students in grades 6-12. The primary research objective was to measure the impact the training and subsequent use of the WE curriculum had on teachers' behavior, confidence, and self-efficacy in teaching about…

The purpose of this research was to manipulate the component of confidence found in Keller's ARCS Model to enhance the confidence and performance of undergraduate students enrolled in an online course at a Texas University. This experiment used SAM Office 2003 and WebCT for the delivery of the tactics, strategies, confidence-enhancing e-mails…

In 3 studies, participants viewed sequences of multiattribute objects (e.g., colored shapes) appearing with varying frequencies and judged the likelihood of the attributes of those objects. Judged probabilities reflected a compromise between (a) the frequency with which each attribute appeared and (b) the ignorance prior probability cued by the…

Faced with limited resources, schools require tools that increase the accuracy and efficiency of functional behavioral assessment. Yarbrough and Carr (2000) provided evidence that informant confidence ratings of the likelihood of problem behavior in specific situations offered a promising tool for predicting the accuracy of function-based…

Rigorous comparison of the reliability coefficients of several tests or measurement procedures requires a sampling theory for the coefficients. This paper summarizes the important aspects of the sampling theory for Cronbach's (1951) coefficient alpha--a widely used internal consistency coefficient. This theory enables researchers to test a…

This article attempts to measure team-player frame of mind. (JS)

The effects of feedback are largely determined by the students' perception of his original response. Feedback is most advantageous when it follows a response in which the student has high confidence. Findings are based on a study of college students working with a programmed text. (MV)

On a multiple-choice test in which each item has k alternative responses, the test taker is permitted to choose any subset which he believes contains the one correct answer. A scoring system is devised. (Author/CTM)

Confidence intervals (CIs) for means are frequently advocated as alternatives to null hypothesis significance testing (NHST), for which a common theme in the debate is that conclusions from CIs and NHST should be mutually consistent. The authors examined a class of CIs for which the conclusions are said to be inconsistent with NHST in…

A dicussion is provided of some statistical measures and graphical information that, when used as feedback to the student, facilitates his ability to assess his own uncertainty. These measures and graphs, which result from the application of least squares analysis and information theory to decision-theoretic testing, provide the student with the…

Testing procedures which involve testees assigning probabilities of correctness to all multiple choice alternatives is examined. Two basic assumptions in these procedures are reviewed. Empirical examinee response data are examined and it is suggested that these assumptions should not be taken lightly in empirical studies of personal probability…
