Recently, researchers interested in the nature and origins of semantic representations have investigated an especially informative case study: The acquisition of the word "most"--a quantifier which by all accounts demands a sophisticated second-order logic, and which therefore poses an interesting challenge to theories of language…

Visualizations and visual models are of substantial importance for science learning (Harrison and Treagust, 2000), and it seems impossible to study chemistry without visualizations. More specifically, the combination of visualizations with text is especially beneficial for learning when dual coding is fostered (Mayer, 2014). However, at the same…

Topics in trigonometry have not been well-studied, especially with college-level students. Thus, despite providing a venue for important concepts such as notions of proof and algebraic skill, the process of verifying trigonometric identities, or VTI, has not been thoroughly explored. This study attempts to remedy this gap in the literature by…

Background: After 14 years of civil war and two rounds of democratic elections, Liberia is working to reduce child abuse and exploitation. Young children's perceptions on protection and risk are rarely elicited to inform program planning and intervention. Objective: The aim of the present study was to explore young children's perceptions of child…

We examined developmental changes in children's inductive inferences about biological concepts as a function of knowledge of properties and concepts. Specifically, 4- to 5-year-olds and 9- to 10-year-olds were taught either familiar or unfamiliar internal, external, or functional properties about known and unknown target animals. Children were…

Using animated computer-generated graphics to assist instruction has recently attracted the attention of educators and educational researchers. The specific focus of this study is to compare the influence of animated visuals with static visuals on college students' understanding of organic reaction mechanisms in chemistry. This study also focuses…

The National Science Education Standards [National Research Council (1996) National science education standards. Washington, DC: National Academy Press] recommend that students understand the apparent patterns of motion of the sun, moon and stars by the end of early elementary school. However, little information exists on students' ability to…

The assimilation and synthesis of knowledge is essential for students to be successful in chemistry, yet not all students synthesize knowledge as intended. The study used the Learning Preference Checklist to classify students into one of three learning modalities--visual, auditory, or kinesthetic (VAK). It also used the Kolb Learning Style…

Examined infants' use of configural and physical knowledge in segregating three-dimensional adjacent displays. Found that infants do use configural knowledge: they expect similar parts to belong to same unit and dissimilar parts to belong to distinct units. Also found that physical knowledge, such as impenetrability and support, influences their…

Summarizes findings on infants' capacity for object segregation. Maintains that infants can use featural and experiential information for segregation and individuation purposes long before 12 months of age. Disputes the claim that formation of object categories awaits early word learning, but acknowledges that language may play a key role in…

Responds to Needham and Baillargeon's criticisms and offers an alternative resolution of the conflicting results between the laboratories regarding abilities of infants less than 12 months to use property/featural information for object individuation. Maintains that kind concepts are acquired as infants approach their first birthday and that…

Research has shown that technology-enhanced visualizations can improve inquiry learning in science when they are designed to support knowledge integration. Visualizations play an especially important role in supporting science learning at elementary and middle school levels because they can make unseen and complex processes visible. We identify 4…
