According to the Multiple Deficit Model, comorbidity results when the genetic and environmental risk factors that increase the liability for a disorder are domain-general. In order to explore the role of domain-general etiological risk factors in the co-occurrence of learning-related difficulties, the current meta-analysis compiled 38 studies of…

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…

The concept of angles is important for future geometric knowledge (Arslan et al., 2016; Moore, 2013; Yigit, 2014). However, although Piaget (1948) suggests angles lead to the discovery of lines, angles are typically taught later in schools, after points, lines, and planes (Charles, 2011). Therefore, the way in which angles are taught can affect…

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 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,…

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…

A MyPad as a teaching aid can be a bridge or a border in children's learning of expression and communication, depending on how and why it is used. Onto genetic and phylogenetic aspects are among the most important in a child's development, i. e. teaching children to talk. Multimodality refers to communication and integration using various…

As traditional teaching methods may fail to serve children with special needs, special education (SE) services aim to compensate for the shortcomings of conventional schooling. However, despite of numerous studies on the effectiveness of SE services, the influence of potential selection bias remains a real challenge, and only a few studies have…

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…

Native plants are not typically the kinds of plants that are used in elementary classroom studies of plant biology. More commonly, students sprout beans or investigate with fast plants. At the time the authors started their plant unit (November), the school-yard garden had an abundance of native plants that had just started seeding, including…

This article explores the use of alternative assessments as a way to determine the impact of science instruction on English Language Learners' (ELLs) abilities to comprehend an informational trade book text, both at the level of reading comprehension and at the level of science understanding. This multi-cohort comparison study of 47 fifth grade…

The cycle of duplication and division, known as the "cell cycle," is the essential mechanism by which all living organisms reproduce. This activity allows students to develop an understanding of the main events that occur during the typical eukaryotic cell cycle mostly in the process of mitotic phase that divides the duplicated genetic material…

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…

This study explored how a teaching experiment, which taught double counting with a constructive task assignment according to an ongoing assessment, helped students with mathematics difficulties develop their multiplicative reasoning skills. The participants were two fifth graders with math learning disabilities and one at risk. A micro-genetic…
