The purpose of this study was to develop a core HIV/AIDS knowledge assessment (CHAKA) for students enrolled in counseling-related degree programs. Although there are studies that examined counseling HIV/AIDS knowledge, the instruments that were used were limited in ways that may compromise the accuracy of the inferences that were made. This study…

It has been a concern among educators and academics that U.S. students suffer from a lack of knowledge about the world around them. This is reflected in low history scores, particularly in world history. The common explanation for this is that there is some systematic deficiency in American students, in that they either do not know the material or…

Wireless Sensor Networks (WSNs) are now widely used for monitoring and controlling of systems where human intervention is not desirable or possible. Connected Dominating Sets (CDSs) based topology control in WSNs is one kind of hierarchical method to ensure sufficient coverage while reducing redundant connections in a relatively crowded network.…

As scientific research becomes more data intensive, there is an increasing need for scalable, reliable, and high performance storage systems. Such data repositories must provide both data archival services and rich metadata, and cleanly integrate with large scale computing resources. ROARS is a hybrid approach to distributed storage that provides…

A procedure for estimating the reliability of test scores in the context of ecological momentary assessment (EMA) was proposed to take into account the characteristics of EMA measures. Two commonly used test scores in EMA were considered: the aggregated score (AGGS) and the within-person centered score (WPCS). Conceptually, AGGS and WPCS represent…

This systematic review evaluates the validity, reliability, and clinical utility of outcome measures used to assess self-care skills among children with congenital musculoskeletal conditions and assesses the applicability of these measures for children with osteochondrodysplasia aged 0-12 years. Electronic databases were searched to identify…

The vast majority of the research on student evaluation of instruction has assessed the reliability of groups of courses and yielded either a single reliability coefficient for the entire group, or grouped reliability coefficients for each student evaluation of teaching (SET) item. This manuscript argues that these practices constitute a form of…

Forty-nine percent of the 706 articles published in the "Journal of Agricultural Education" from 1995 to 2012 reported quantitative research with at least one variable measured by a Likert-type scale. Grounded in the classical test theory definition of reliability and the tenets basic to Likert-scale measurement methodology, for the…

Three studies were combined to test the reliability, validity, and factor structure of the imaginative capability scale (ICS). The ICS was a new self-report measure, which was developed to be empirically valid and easy to administer. Study 1 consisted in an exploratory factor analysis to determine the most appropriate structure of the ICS in a…

This paper examines an assessment process within the context of quality, accountability and institutional effectiveness in academia. Considered as one of the most important elements in higher education, the assessment process plays a significant role in contributing to holistic quality as well as the performance of an academic institution. As a…

The purpose of the current study is to develop a "social presence scale" for e-learning environments. A systematic approach was followed for developing the scale. The scale was applied to 461 students registered in seven different programs at Gazi University. The sample was split into two subsamples on a random basis (n1 = 261; n2 =…

Physicians function as clinicians, teachers, and role models within the clinical environment. Negative learning environments have been shown to be due to many factors, including the presence of unprofessional behaviors among clinical teachers. Reliable and valid assessments of clinical teacher performance, including professional behaviors, may…

Background: Identifying what a communication partner is looking at (referential intention) and why (social intention) is essential to successful social communication, and may be challenging for children with social communication deficits. This study explores a clinical task that assesses these intention-reading abilities within an authentic…

The autism spectrum disorder (ASD) diagnostic classifications, according to the DSM-5, include a severity rating. Several screening and/or diagnostic measures, such as the autism diagnostic and observation schedule (ADOS), Childhood Autism Rating Scale (CARS) and social responsiveness scale (SRS) (teacher and parent versions), include an…

The complexity of learning has plagued the educational establishment for decades. Recently, ideas of complexity theory and complex adaptive systems have made headway in how we think of institutions of learning. This study developed and tested an instrument for the modeling of underlying social structures, as an element of complexity, within the…
