The study addresses the association between coaching practices and university admission test performance in Chile. Estimates of coaching effects are reported for test-takers from the private and public school systems. Our results indicate that coaching is associated with variations in test scores. The estimated magnitude of coaching appears to…

Different Information Systems (ISs) have been implemented in many Tanzanian higher education institutions (HEIs) but most of them are not integrated with each other. This study aimed to discover whether these HEIs consider integrated ISs useful in performing different operations especially in decision making. A modified Technology Acceptance Model…

A practicum is beneficial in science learning to provide a concrete manifestation of a topic. This study aimed at creating a simulation-based interactive learning multimedia product to assist students' practicum. The product was developed for the topic of cell metabolism process focusing on the energy in living systems. The study employed the…

Students' test-taking motivation has been found to be a predictor of performance. This study tests whether Shanghai students' conceptions of tests and test-taking motivation differ when the consequence of tests have different foci (i.e., none, country, or personal). A between-subjects experiment with vignette instructions systematically assigned…

Purpose: The main objective of this study was to identify the influence of principal instructional leadership on teacher organizational commitment in junior high schools in Surakarta. This issue arises because there are discrepancies in the findings of previous studies as well as the lack of studies in Indonesia. Accordingly, no definitive…

Increasing linguistic diversity in classrooms has led researchers to examine the validity and fairness of standardized achievement tests, specifically concerning whether test score interpretations are free of bias and score use is fair for all students. This study examined whether mathematics achievement test items that contain complex language…

A tailored testing model employing the beta distribution, whose mean equals the difficulty of an item and whose variance is approximately equal to the sampling variance of the item difficulty, and employing conditional item difficulties, is proposed. (Author)

This article builds on an earlier discussion of the importance of the Type II error (beta) and power to the hypothesis testing process (CE 511 484), and illustrates the methods by which sample size calculations should be employed so as to improve the research process. (Author/CT)

Purpose: Work-integrated learning (WIL) is an integral part of hospitality curriculums in Australia. Experiencing stress during WIL is expected, as students try to balance work and other responsibilities. Previous studies have usually examined the negative impact of stress on individuals. By referring to relevant theories, this paper argues the…

This article proposes the use of the coefficient of determination as a statistic for hypothesis testing in multiple linear regression based on distributions acquired by beta sampling. (Contains 3 figures.)

Google is opening up whole new worlds for internet surfers and researchers everywhere. Google Book Search (books.google.com), which is still in beta after several years of testing, offers the ubiquitous Google search box on its home page. It also has categories of books as well as book cover images that refresh every time the home page is…

Background: Turn 2 Us (T2U) is an elementary school-based mental health promotion and prevention program in New York City. It targets fourth- and fifth-grade students at risk for social/emotional and behavioral problems and provides a range of services to students, staff, and parents. The purpose of this study is to determine if T2U decreases…

A tailored testing model employing the beta distribution, whose mean equals the difficulty of an item and whose variance is approximately equal to the sampling variance of the item difficulty, and employing conditional item difficulties, is proposed. The model provides a procedure by which a minimum number of items of a test, consisting of a set…

Little is known about the influence of language background in problem-based learning (PBL) tutorial groups on group processes and students' academic achievement. This study investigated the relationship between language background, secondary school score, tutorial group processes, and students' academic achievement in PBL. A validated tutorial…

In this paper, we apply sequential one-sided confidence interval estimation procedures with beta-protection to adaptive mastery testing. The procedures of fixed-width and fixed proportional accuracy confidence interval estimation can be viewed as extensions of one-sided confidence interval procedures. It can be shown that the adaptive mastery…
