Recent studies of second language (L2) construction learning using artificial linguistic systems have begun to closely examine the role of individual differences, including personality. In such studies, adult participants learn form-meaning mappings after exposure, with scores on generalization tests as a standard criterion for learning. This…

Peer assessment can be conducted online with rapid development of online learning technology. The current study was conducted empirically to investigate peer rating accuracy and student learning outcomes in online peer assessments, comparing compulsory and voluntary peer assessment. Section 1 (N = 93) was assigned to the voluntary group and…

This research study explores the relationship between the socio-cognitive concept of mindfulness and university educators' learning design conceptualisations. The multi-method research strategy utilises a concept-mapping exercise to reveal learning designer mental models for comparison with Langer Mindfulness Scale scores and critical event…

This study compared oral health behaviours and barriers to dental care among preschool children with and without ASD, and evaluated dental knowledge and attitudes of their parents. 257 preschoolers with ASD and an age- and gender-matched control sample were recruited. Children with ASD had less frequently performed tooth-brushing and used…

There are currently many mathematics anxiety rating scales designed typically for adult and older children populations, yet there remains a lack of assessment tools for younger children (< 7 years of age) despite a recent focus on this age range. Following previous testing and validation, the 26-item iteration of the Children's Mathematics…

This article examines whether the way that PISA models item outcomes in mathematics affects the validity of its country rankings. As an alternative to PISA methodology, a two-parameter logistic model is applied to PISA mathematics item data from Italy and Spain for the year 2009. In the estimation procedure, item difficulty and dispersion…

Standardized concept inventories (CIs) have been widely used in science, technology, engineering, and mathematics education for assessment of student learning. In practice, there have been concerns regarding the length of the test and possible test-retest memory effect. To address these issues, a recent study developed a method to split a CI into…

Ensuring postsecondary readiness is a goal of K-12 education, but it is unclear whether high school students should get different messages about the required levels of academic preparation depending on their postsecondary trajectories. This study estimated readiness benchmark scores on a college admissions test predictive of earning good grades in…

In this investigation, differences in the reading performance as a function of degree of economic disadvantage for Texas Grade 3 students were examined. Data were obtained from the Texas Education Agency on all Texas Grade 3 students for the 2012-2013, 2013-2014, and 2014-2015 school years. In all analyses, statistically significant differences,…

Here we report on the development process of the Inquiry Oriented Instructional Measure (IOIM), an instrument for scoring a lesson along seven inquiry-oriented instructional practices. The development of the IOIM was a multi-phase, iterative process that included reviewing K-16 research literature, analyzing videos of classroom instruction, and…

Theory of mind (ToM) skills involve young children's mentalizing ability to be aware of their own selves and other individuals' thoughts, beliefs, desires, and intentions (mental states). The social cognition skills are essential for processing complex social relations and overcoming interpersonal difficulties in communication. Previous studies…

This study aims to obtain information about the modelling situations related to the topic by performing concentration analysis of teacher candidates' responses to Force Concept Inventory (FCI). The research was conducted using survey model, which is a quantitative research method. The study was carried out in the fall semester of the academic year…

When item scores are ordered categorical, categorical omega can be computed based on the parameter estimates from a factor analysis model using frequentist estimators such as diagonally weighted least squares. When the sample size is relatively small and thresholds are different across items, using diagonally weighted least squares can yield a…

The federal Race to the Top competition provided significant impetus for states to adopt value-added models as a part of their teacher evaluation systems. Such models typically link students to their teachers in the spring semester when statewide tests are administered and estimate a teacher's performance based on his or her students' learning…

To what extent, if at all, did the introduction of free primary education in Kenya in 2003 have positive equity effects, in terms of both access and achievement. Access is based on the number of candidates sitting the Kenya Certificate of Primary Education (KCPE) examination and the KCPE score is used to measure achievement levels. The study uses…
