Young children can struggle to learn difficult disciplinary content and important skills for practicing science. Problem-based learning (PBL) may be useful for addressing such difficulties, yet evidence to support its usefulness in elementary school-aged children is limited. We considered the role of a PBL unit in improving students' genetics…

Educators expect that students be able to make informed decisions about science-related problems in their everyday lives. Engaging science in such problems often entails evaluating available evidence for given arguments. This study explores how students use inscriptions as evidence to argue about socioscientific issues. Fifth- and sixth-grade…

Genetics has become increasingly important in everyday life, a fact that is reflected in state and national science education standards. This study examines the relationship between 474 fifth graders' understandings of the core ideas of "inheritance of traits" and "variation of traits". A confirmatory factor analysis,…

This article describes a self-guided, story-like game with creative drawing for grades 3-5 that teaches the evolution concepts of adaptation, natural selection, ecosystem dynamics, inheritance, and mutation following the "Next Generation Science Standards" ("NGSS"). Drawing reinforces concepts through emphasis on students'…

This collective case study uses a design-based research approach to investigate the role of 3D pens, an emerging technology, in fostering creativity during a lesson on biomes, genetics, and heredity with learners in six classes of 4th and 5th grade students from rural Michigan and Idaho. Data analyzed included video of the classroom lessons,…

Evolution by natural selection is key to understanding life and of considerable practical importance in public health, medicine, biotechnology, and agriculture. "The Next Generation Science Standards" (NGSS) include natural selection among several evolutionary concepts that all third-graders should know. This article explores a novel…

In this digital era, a fundamental challenge is to design digital reading materials in such a way that they improve children's reading skills. Since reading books is challenging for many fifth graders--particularly for those genetically susceptible to attention problems--the researchers hypothesized that guidance from a digital Pedagogical Agent…

Previous literature has indicated an important association between reading comprehension and both attention-deficit/hyperactivity disorder (ADHD) and homework habits. This investigation sought to extend previous knowledge by providing information about how ADHD and homework behavior (i.e., completing homework regularly) may jointly influence…

This study explores upper-elementary and early-middle-school students' ideas about cells and inheritance and describes patterns of understanding for these topics. Data came from students' responses to embedded assessments included in a technology-enhanced curriculum designed to help students learn about cells and heredity. Our findings suggest…

Research on the development of reading skills through the primary school years has pointed to the importance of individual differences in initial ability as well as the growth of those skills. Additionally, it has been theorized that reading skills develop incrementally. The present study examined the genetic and environmental influences on 2…

"Non-native organisms are a major threat to biodiversity". This statement is often made by biologists, but general conclusions cannot be drawn easily because of contradictory evidence. To introduce pupils aged 11-14 years to this topic, we employed an educational program dealing with non-native animals in Central Europe. The pupils took…

The purpose of this study was to investigate primary students' learning through participation in an out-of-school enrichment programme, held in a science centre, which focused on DNA and genes and whether participation in the programme led to an increased understanding of inheritance as well as promoted interest in the topic. The sample consisted…

This study was carried out in the context of formative assessment where assessment and learning were integrated to enhance both teaching and learning. The purpose of the study was to: (a) identify pupils' ideas about biological inheritance through the use of a concept cartoon, pupils' drawings and talk, and (b) devise scaffolding structures that…

The purpose of this study was to investigate how concept cartoons, together with other diagnostic and scaffolding tools, could be used in formative assessment, to stimulate talk and argumentation among students in small groups, as part of peer-assessment and self-assessment; and to provide diagnostic feedback about students' misconceptions to the…

The present study examined the effect of consanguineous marriage in the Arab community on reading disabilities of offspring. It examined whether the rate of reading disabilities was higher among offspring of first-cousin parents than offspring of unrelated parents; and whether reading-disabled children of first-cousin parents were more disabled in…
