Several researchers have suggested that the maintenance of global coherence (topic maintenance) and local coherence (maintenance between utterances) in discourse requires cognitive resources. This study directly tests this hypothesis by examining the relationship between cognitive variables and coherence in narrative discourse produced by…

Learning about statistics is a lot like learning about science: the learning is more meaningful if you can actively explore. This fifth installment of "Explorations in Statistics" revisits power, a concept fundamental to the test of a null hypothesis. Power is the probability that we reject the null hypothesis when it is false. Four…

Given the prevalence of low-stakes testing internationally (e.g., NAEP, TIMSS, PIRLS), it is crucial to try to better understand examinee motivation in these contexts. In the current study, mixture modeling results supported three different profiles of test-taking effort over the course of five tests. Classes 1 and 2 had varying levels of effort…

The duplex design by Bock and Mislevy for school-based testing is revisited and evaluated as a potential platform in test-based accountability assessments today. We conclude that the model could be useful in meeting the many competing demands of today's test-based accountability assessments, although many research questions will need to be…

Almost everything people have ever done has involved materials. Historical evidence indicates that "engineered materials" have been available and utilized for the benefit of humankind since the Neolithic period, beginning about 10,000 BC. Some of these materials have been in existence for thousands of years. At first, materials consisted of wood,…

There is a general assumption that a more controlled or more focused attentional state is beneficial for most cognitive tasks. However, there has been a growing realization that creative problem solving tasks, such as the Remote Associates Task (RAT), may benefit from a less controlled solution approach. To test this hypothesis, in a 2x2 design,…

This exploratory research study was conducted to examine federally-mandated annual English language proficiency (ELP) assessment of English language learners (ELLs) and their use of accommodations on the assessment. The literature was examined for differences and similarities between the three types of testing scenarios as well as identifying gaps…

The aim of this study is to determine the test-retest reproducibility of the seven-item Short-Form Berg Balance Scale (SFBBS) and the five-item Short-Form Postural Assessment Scale for Stroke Patients (SFPASS) in individuals with chronic stroke. Fifty-two chronic stroke patients from two rehabilitation departments were included in the study. Both…

The purpose of this study was to examine Mississippi Delta area public high school counselors' and principals' perception of the impact of SATP2 testing on counselors' services to students in order to determine whether or not testing responsibilities have an adverse effect on counselors' delivery of services to students. This study was similar to…

Six Practice Tests for the iBT gives students plenty of practice as they prepare for the Internet-based TOEFL (iBT) or the new form of the institutional TOEFL (ITP). This new book/audio set contains a concise description of the TOEFL and the types of questions in each section, as well as six full-length tests that have not been published before.…

In this dissertation, I provide a new analysis of the Vietnamese vowel system as a system with fourteen monophthongs and nineteen diphthongs based on phonetic and phonological data. I propose that these Vietnamese contour vowels - /ie/, /[turned m]?/ and /uo/-should be grouped with these eleven monophthongs /i e epsilon a [turned a] ? ? [turned m]…

I criticize the typewriting model and linear writing structure of Microsoft Word software for writing in the computer. I problematize bodily movement in writing that the error of the software disregards. In this research, writing activity is viewed as bodily, spatial and mediated activity under the premise of the unity of consciousness and…

Research on the impact of mobility on children's academics has varied, although the majority indicated negative consequences. A gap in the current literature remains regarding how the mobility of children of service members, who attended public schools, relates to academic performance. The purpose of this study was to investigate the relationship…

Background: In recent years, the researchers had worked on attachment style theory in studying different aspects of individual and social life of adults and announce that attachment style is related to most behavior, thought and motivational behaviors. The aim of the current study was investigating the relationship between attachment styles with…

We describe an activity that allows students to experience the full process of a statistical investigation, from generating the research question, to collecting data and testing a hypothesis. Implementation of the activity is described both with and without use of clickers, handheld remotes that allow instant data collection.
