This study aims to identify which socio-economic status (SES) variables have the best predictive validity for academic achievement, based on the international data sets of the Programme for International Student Assessment (PISA) in 2012, 2009, 2006, and 2003. From among 10 SES measures, two composite variables - Index of economic, social and…

One of the major issues in L2 learning and cognitive styles is the ambiguity of these concepts. A solution to this issue should involve the following two aspects. First, studies of factorial validity should be conducted with empirical data, and with an appropriate analysis using a theoretically well-developed scale. Second, such studies should…

In 2018, 26 states administered a college admissions test to all public school juniors. Nearly half of those states proposed to use those scores as their academic achievement indicators for federal accountability under the Every Student Succeeds Act (ESSA); many others are planning to use those scores for other accountability purposes.…

This paper presents an innovative method to tackle the automatic evaluation of programming assignments with an approach based on well-founded assessment theories (Classical Test Theory (CTT) and Item Response Theory (IRT)) instead of heuristic assessment as in other systems. CTT and/or IRT are used to grade the results of different items of…

Studies conducted in USA, Dubai, South Africa, Nigeria, Uganda, central region of Kenya and some part of Nyanza region have revealed that principals' leadership styles influence performance in schools. Leadership style was found to contribute 32.8% to the students' performance in Kinangop. However, there was no information about the influence…

The aim of this study was to explore preschool teachers' evaluation standards and searching strategies during their online searching process, focusing on the difference between pre-service and in-service teachers. A total of 408 pre-service and in-service preschool teachers in Taiwan participated in the survey research. The validity and…

This study investigated the cross-cultural validity of the Preschool Learning Behavior Scale (PLBS) in the Chinese cultural context. Multiple approaches were used for this purpose, including exploratory factor analysis, confirmatory factor analysis, criterion-related validity evidence, and internal consistency reliability estimates. The findings…

Several studies related to mathematical proof have been done by many researchers on high-level materials, but not yet examined on the material of transformation geometry. The aim of this research is identification learning obstacles pre-service teachers on transformation geometry. This study is qualitative research; data were collected from…

The purpose of the current study was to examine the validity and diagnostic accuracy of the "Intervention Selection Profile--Social Skills" (ISP-SS), a brief social skills assessment tool intended for use with students in need of Tier 2 intervention. Participants included 160 elementary and middle school students who had been identified…

Threats to construct validity should be reduced to a minimum. If true, sources of bias, namely raters, items, tests as well as gender, age, race, language background, culture, and socio-economic status need to be spotted and removed. This study investigates raters' experience, language background, and the choice of essay prompt as potential…

The extant literature regarding psychometric properties of measures of subclinical adult autism traits is sparse. The current study investigated the validity and internal consistency reliability of the 26-item Autism Quotient (AQ-26), a self-report measure of autism traits, in a nonclinical young adult sample. Results indicated significantly…

Leader self-efficacy (LSE) is a construct studied in adults and college students which is associated with leader emergence, individual performance, and group performance. However, to date, it has not been heavily examined in youth. Therefore, a five-item youth LSE scale was created which can aid in further research of this construct. This holds…

The purpose of this study was to examine construct validity of methods of calculating lexical diversity in written narrative samples relative to children's performance on a reading vocabulary measure. For 234 children in first to fifth grade, written narratives were examined and compared between grades for number of different words (NDW), total…

Objective: As eating disorders (EDs) often emerge during college, managing EDs would ideally integrate prevention and treatment. To achieve this goal, an efficient tool is needed that detects clinical symptoms and level of risk. This study evaluated the performance of a screen designed to identify individuals at risk for or with an ED.…

There currently exist no self-report measures of social camouflaging behaviours (strategies used to compensate for or mask autistic characteristics during social interactions). The Camouflaging Autistic Traits Questionnaire (CAT-Q) was developed from autistic adults' experiences of camouflaging, and was administered online to 354 autistic and 478…
