Van der Linden's hierarchical model for responses and response times can be used in order to infer the ability and mental speed of test takers from their responses and response times in an educational test. A standard approach for this is maximum likelihood estimation. In real-world applications, the data of some test takers might be partly…

Speech-language pathologists serving individuals with aphasia must make many decisions regarding assessment and intervention practices to support comprehension and expression of language. Each of these decisions can influence the effectiveness of therapy and long-term functional outcomes for individuals with aphasia. One factor that must be…

The study tested the hypotheses that boys will have an advantage learning the fractions number line and this advantage will be mediated by spatial abilities. Fractions number line and, as a contrast, fractions arithmetic performance were assessed for 342 adolescents, as was their intelligence, working memory, and various spatial abilities. Boys…

Due to the legal implementation of inclusion in the German school system, teachers face the challenge of implementing the joint learning of pupils with and without special educational needs in the classroom. But how do they do this? How do teachers differentiate between pupils in classroom practices and what differences do they produce throughout…

This study aims to develop a scale for determining the anxiety levels of secondary school students in situations that require them to use their spatial skills. The scale was developed in three stages. In the first stage, after expert assessments, a pilot study was conducted. In the second stage, the scale was applied to all students (N=348)…

Education policies in South Africa are aimed at redressing the legacies of under- and inequitable development, and at making learning opportunities available to all the citizens of this country. The "Amended Norms and Standards for School Funding Policy (2006)," which also outlines the no-fee policy, should be implemented in South…

Historically, there has been concern about students losing reading ability over extended breaks from school, commonly in the summer, but studies of this phenomenon have produced inconsistent results. We applied exploratory visual analysis of multiple datasets to examine whether students in Grades K-5 appear to lose or improve in various reading…

This study investigated potential inequalities in a bilingual education program where secondary school students are streamed into two strands with different degrees of exposure to the target language based on their proficiency: high exposure (HE) and low exposure (LE). Drawing on classroom registers (Christie, 2005), appraisal theory (Martin &…

The purpose of this practice paper is to promote the teaching of learners with neurodevelopmental conditions from a neurodiverse perspective. The challenge teachers face in having to draw on up-to-date research evidence and theoretical perspectives, and align these with practical considerations to generate contextualised teaching strategies, are…

Students' socioeconomic status (SES) is central to much research and policy deliberation on educational inequalities. However, the SES model is under severe stress for several reasons. SES is an ill-defined concept, unlike parental education or family income. SES measures are frequently based on proxy reports from students; these are generally…

A longitudinal study with 45 children (Hispanic, 13%; non-Hispanic, 87%) investigated whether the early production of non-referential beat and flip gestures, as opposed to referential iconic gestures, in parent-child naturalistic interactions from 14 to 58 months old predicts narrative abilities at age 5. Results revealed that only non-referential…

Self-efficacy and spatial anxiety towards geometry are stated to be effective to improve teachers' attitudes towards geometry. Therefore, it is necessary to determine the effect of geometry self-efficacy and spatial anxiety on attitude towards geometry. This determines the extent to which the pre-service primary school teachers' geometry…

Background: Coding has been added to school curricula in several countries, being one of the necessary competencies of the 21st century. Although it has also been suggested to foster the development of several cognitive skills such as computational thinking and problem-solving, studies on the effects of coding are very limited, provide mixed…

In sentences such as "Some dogs are mammals," the literal semantic meaning ("Some 'and possibly all' dogs are mammals") conflicts with the pragmatic meaning ("'Not all' dogs are mammals," known as a "scalar implicature"). Prior work has shown that adults vary widely in the extent to which they adopt the…

Spatial skills are important for student success in STEM disciplines at the K-12 educational level. Teachers' spatial skills and feelings about completing spatial tasks influence their teaching as well as their students' spatial learning. However, the relation between teachers' spatial skills and their spatial anxiety is not well understood. Here…
