Explanatory item response models (EIRMs) have been applied to investigate the effects of person covariates, item covariates, and their interactions in the fields of reading education and psycholinguistics. In practice, it is often assumed that the relationships between the covariates and the logit transformation of item response probability are…

Short message service (SMS or text messaging) surveys can collect data quickly and inexpensively. However, SMS surveys have space constraints that pose difficulties to questionnaire designers: Questions can only be 160 characters or less, surveys must be short, and many respondents use phones with small screens. In this article, we compare SMS and…

The aim of this study is to examine how critically and creatively the students express their feelings and thoughts by using emoticons. In the first part, how the students expressed what they read by using emoticons was examined. In order to assess their skills for reading comprehension and the skills for expressing what they understood through…

Mechanisms causing item nonresponses in large-scale assessments are often said to be nonignorable. Parameter estimates can be biased if nonignorable missing data mechanisms are not adequately modeled. In trend analyses, it is plausible for the missing data mechanism and the percentage of missing values to change over time. In this article, we…

Financial therapy is used to address the psychological, emotional, and behavioral components involved in the process of learning and utilizing new financial literacy skills. This study describes the use of a manualized financial therapy financial therapy intervention, the Five-Step Model, as it is piloted in a group setting. Current economic…

We used a contingent acoustical feedback procedure to increase appropriate walking and decrease toe walking exhibited by a young boy with autism. After a pre-treatment screening assessment suggested that toe walking was maintained by automatic reinforcement, we paired an auditory stimulus (i.e., a clicking sound) with access to a preferred item to…

When is it appropriate, and consistent with ethical standards, for evaluators to modify reports in response to "requests" from clients to do so? Some evaluators may view any pressure to make any changes in their reports as an attack on their independence. While, clearly, it is not acceptable for evaluators to be asked to distort or…

Nonresponse is an increasing problem in sample surveys and student surveys are no exception. When nonrespondents differ from respondents in meaningful ways, respondents may not be representative of the population. Hence, analyses of survey data may be biased and not generalizable to the population. In this chapter we provide an overview of…

Purpose: The contribution of tissue mechanical response to vocal fatigue is poorly understood. This study investigated the fatigue response of vocal fold tissues to large-amplitude vibration exposure at phonatory frequencies, using an ex vivo ovine model. Method: Twelve sheep vocal fold mucosal specimens were subjected to sinusoidal, simple-shear…

An approach to scoring tests with binary items, referred to as D-scoring method, was previously developed as a classical analog to basic models in item response theory (IRT) for binary items. As some tests include polytomous items, this study offers an approach to D-scoring of such items and parallels the results with those obtained under the…

Implementation of evidence-based practices (EBPs) is paramount to students' development of mathematics proficiency. This study investigated "practice-based evidence" of interventionists' actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data collected in a…

Implementation of evidence-based practices (EBPs) is paramount to students' development of mathematics proficiency. This study investigated "practice-based evidence" (Green, 2008) of interventionists' actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data…

Self-report is a fundamental research tool for the social sciences. Despite quantitative surveys being the workhorses of the self-report stable, few researchers question their format--often blindly using some form of Labelled Categorical Scale (Likert-type). This study presents a brief review of the current literature examining the efficacy of…

Purpose: Emotional verbal fluency (Emo-VF) has the potential to expand neuropsychological assessment by providing information about affective memory retrieval. The usability of Emo-VF is limited, however, by significant variations in task administration and the lack of information about Emo-VF responses. This study investigated verbal productivity…
