We discuss new measures in assessing the skill level of students based on their interactions with the Socratic homework tutor, MasteringPhysics. We show that the measurement of the difficulty of problems for a given student as determined by the time to first correct response, the number of incorrect responses without advice, and hints have high reliability (96%). As an immediate application, we...

With fast development in e-learning, assessment plays an important role between teaching and learning. A good e-learning system is not only with good teaching strategy and better learning resources but also proper assessment model. In this paper, we proposed an assessment meta-data and assessment analysis feedback for recently e-learning environments. There are several proper feedback for teach...

A large British sample completed measures of job autonomy and satisfaction as well as work discrimination and attitudes to authority measures along with a new surveillance at work measure. The new 16 item surveillance at work measure factored into two clear factors which reflected positive and negative attitudes to surveillance. Higher scores on Negative Aspects of Surveillance were significant...

This paper evaluates certain guidelines for writing multiple-choice test items. The analysis of the responses of 5013 subjects to 630 items from 21 university classroom achievement tests suggests that an option should not differ in terms of heterogeneous content because such error has a slight but harmful effect on item discrimination. This also occurs with the "None of the above" option when i...

ABSTRACT The burnout variable has been studied in different professions; however, it presents challenges its measurement. present study provides evidence of validity based on the internal structure Burnout Syndrome Assessment Scale Public Security Workers (EASB-SP) and estimation item parameters through Item Response Theory (IRT). A total 10,885 public security agents from all states Brazil par...

We investigated the trade-off between capacity and precision in visual working memory with two different tasks: delayed discrimination and recall. The stimuli were radial frequency patterns that require global pooling of local visual features. The thresholds in delayed amplitude discrimination were measured with a two-interval, forced-choice setup using the Quest procedure. In the recall experi...

In response to views on public's right to know, there is growing attention to item disclosure - release of items, answer keys, and performance data to the public - in medical licensure examinations and their potential impact on the test's ability to measure competence and select qualified candidates. Recent debates on this issue have sparked legislative action internationally, including South K...

This study investigates the impact of item parameter drift (IPD) on parameter and ability estimation when the underlying measurement model fits a mixture distribution, thereby violating the item invariance property of unidimensional item response theory (IRT) models. An empirical study was conducted to demonstrate the occurrence of both IPD and an underlying mixture distribution using real-worl...

BACKGROUND AND OBJECTIVES The interactive approach of a journal club has been described in the medical education literature. The aim of this investigation is to present an assessment of journal club as a tool to address the question whether residents read more and critically. METHODS This study reports the performance of medical residents in anesthesiology from the Clinics Hospital - Universi...

A study of lhe relations between the perceptive similarity of voices and physical measures of the speech signal has been carried out. The goal of this study was to identify a set of acoustic parameters which contribute mosl to the voice discrimination process. We worked on a corpus of Iogatoms CVCV. Ten male speakers uttering nine items were considered and a single sample of each item was used....
