Many undergraduate chemistry students struggle to understand the concept of stereoisomers, molecules that have the same molecular formula and sequence of bonded atoms but are different in how their atoms are oriented in space. Our goal in this study is to improve stereoisomer instruction by getting participants actively involved in the lesson.…

Standard Australian reading assessment tests are criticized for being culturally inappropriate for use with Australian Indigenous children, particularly for those living in remote and very remote regions, as these tests are culturally biased towards mainstream Australian culture and imperceptive to Indigenous knowledge, language, concepts, and…

Spatial ability has been shown the positive correlations with the mathematics achievement of typically developing children. However, whether there is a relationship between spatial ability and mathematics achievement in deaf children and the mechanisms that underlie the relationship remain unknown. 256 deaf children in Grades 3 to 9 in two special…

The purpose of this study was to explore geometry spatial mathematical reasoning in Grade nine Annual National Assessments, South Africa. Conceptual Blending was the guiding theory. Document analysis within the exploratory case study was used to explore available data, the 2014 Annual National Assessment learners' scripts (n=1250). Results…

Elementary school students often lack a conceptual understanding of linear measurement, which is revealed by their poor performance when the object to be measured is not aligned with the start of the ruler. Instead of correctly counting the units that correspond to the object (e.g., inches or centimeters), children often use 1 of 2 incorrect…

Abstract Few studies have examined how socioeconomic status (SES) affects two essential parts of human development, namely vocabulary and reading comprehension, in children facing severe poverty. The Roma population is the largest minority group in Europe, the majority of whom live in severe poverty. This study compared the development of 322 Roma…

This exploratory study was designed to evaluate the interplay of students' rate and comprehension in independent silent reading of accessible text, within the frameworks of the Simple View of Reading and the RAND Reading Study Group. In the first phase, 61 sixth graders were given a reading test (GRADE), a motivation questionnaire, and an…

Promoting students' ability to engage in discipline-specific practices is a central goal of chemistry education. Yet if instruction is to meaningfully foster such ability, we must first understand students' reasoning during these practices. By characterizing constraints on chemistry students' reasoning, we can design instruction that targets this…

The study aim was to explore the relationship between a developmental assessment at preschool age and an intelligence quotient (IQ) assessment at school age. One hundred sixty-two children were assessed at 2.5 years with the Bayley Scales of Infant and Toddler Development--Third Edition (Bayley-III) and then at 6.5 years with the Wechsler…

The disproportional representation of students from various demographic subgroups within identified gifted and talented populations has long frustrated policy makers, education advocates, researchers practitioners within the field, and those concerned with societal inequality in general. Despite the prevalence of articles in the media reporting on…

This study aims to analyse and describe the ideas of pupils (aged 10-15 years) about ID. Overall 2324 pupils (without disability) from 23 Czech primary schools of the so-called mainstream education participated in the study. Pupils' concepts associated with ID were analysed using mind mapping methods. It was found that an overall frequency of…

In the last few years, engaging students to create digital games has been a pole of attraction for many teachers and researchers, resulting in highly positive learning experiences and promoting their thinking skills, e.g., programming and computational thinking (CT) skills. Researchers have already stated about the need for further research not…

This study examined psychometric characteristics of the Diagnostic Analysis of Nonverbal Accuracy--Second Edition (DANVA-2) in 121 children, ages 6 to 13 years, with high-functioning autism spectrum disorder (HFASD). Internal consistency for adult and child faces subtests were 0.70 and 0.75, respectively. Immediate test-retest reliability in the…

Three aspects of cognition (fluid intelligence, executive functioning, and crystallized intelligence) in pre-K were examined as predictors of math and reading achievement in kindergarten among an economically diverse sample of 198 African American children. From a variable-centered perspective, confirmatory factor analyses revealed that the three…

Background: This article casts the analytical spotlight on the practice of within-class homogeneous (same) ability grouping where learners are placed in small groups for instruction based on their perceived performances, reading levels and interest. Very few studies have focused on within-class ability grouping, especially in a South African…
