Do individual differences in children’s curiosity relate to their inquiry-based learning?

This study investigates how individual differences in 7- to 9-year-olds' curiosity relate to the inquiry-learning process and outcomes in environments differing in structure. The focus on curiosity as individual differences variable was motivated by the importance of curiosity in science education, and uncertainty being central to both the definition of curiosity and the inquiry-learning environment. Curiosity was assessed with the Underwater Exploration game (Jirout, J., & Klahr, D. (2012). Children's scientific curiosity: In search of an operational definition of an elusive concept. Developmental Review, 32, 125–160. doi:10.1016/j.dr.2012.04.002), and inquiry-based learning with the newly developed Scientific Discovery task, which focuses on the principle of designing informative experiments. Structure of the inquiry-learning environment was manipulated by explaining this principle or not. As intelligence relates to learning and possibly curiosity, it was taken into account. Results showed that children's curiosity was positively related to their knowledge acquisition, but not to their quality of exploration. For low intelligent children, environment structure positively affected their quality of exploration, but not their knowledge acquisition. There was no interaction between curiosity and environment structure. These results support the existence of two distinct inquiry-based learning processes – the designing of experiments, on the one hand, and the reflection on performed experiments, on the other – and link children's curiosity to the latter process.

Discussion on coupling mechanism of asymmetric CRLH/RH TL coupler

INTRODUCTION In recent years metamaterials, more commonly referred to as left-handed materials, have stimulated great interests in the scientific and engineering field. These artificial materials, which were first theorized by Veselago (1968) and experimentally realized by Shelby et al.(2001), can exhibit specific electromag- netic properties not commonly found in nature. The approach of using transmission line theory was veri- fied to be an efficient design tool for metamaterials applica…     

Land cover change in Ningbo and its surrounding area of Zhejiang Province,1987～2000

INTRODUCTION Land use and land cover change (LUCC) has become an increasingly important aspect of global environmental change and is a multi-disciplinary subject where geophysicist, bio-physicists and socio-economists meet one another. Land cover is an expression of human activities and, as such, changes with changes in land use and management (Louisa and Antonio, 2001), and land cover change could be regarded as change in biotic diversity, actual and potential productivity, soil quality…

The effect of causal diagrams on text learning

We examined the effect of studying a causal diagram on comprehension of causal relationships from an expository science text. A causal diagram is a type of visual display that explicitly represents cause-effect relationships. In Experiment 1, readers between conditions did not differ with respect to memory for main ideas, but the readers who studied the causal diagram while reading the text understood better the five causal sequences in the text even when study time was controlled. Participants in Experiment 2 studied only the causal diagram or only the text. There were no differences in memory for main ideas or the causal sequences between these groups. Results indicate that causal diagrams are not merely redundant with text and that causal diagrams affect understanding of causal relationships in the absence of a text. These findings supported the causal explication hypothesis, which states that causal diagrams improve comprehension by explicitly representing the implicit causal structure of the text in a visual format.     

Connecting Children's Stories to Children's Literature: Meeting Diversity Needs

Combining children's natural storytelling abilities with quality multicultural literature serves to enhance their language skills and students' appreciation of cultural differences. Narrative abilities—particularly stories—are a natural vehicle for building on children's oral language skills and develop literacy with print. If the stories have a multicultural focus, it is only natural that readers and participants will develop an appreciation of both cultural similarities and differences.

Teacher attributions for children's attention‐deficit/hyperactivity disorder behaviors predict experiences with children and with classroom behavioral management in a summer program practicum

Elementary school teachers often implement classroom behavioral management systems to address student misbehavior. Common problems targeted by these systems are the inattentive, hyperactive, and impulsive behaviors characteristic of attention‐deficit/hyperactivity disorder (ADHD). This study examined teachers' attributions for why children display ADHD behaviors, and how such attributions affect their experiences with children in the context of interventions to manage these behaviors. Participants were 32 preservice teachers undertaking a practicum in a summer program for 137 children (Grades 1–3), some of whom had ADHD. Teachers were trained to implement classroom‐wide behavioral management. Teachers' attributions for children's ADHD behaviors were assessed using a vignette measure, before teachers had met their students or begun training on intervention techniques. When controlling for attributions regarding oppositional behavior, teachers' initial attributions for ADHD behaviors as less internal/controllable predicted children reporting more positive relationships with that teacher during the summer program. Teachers' initial attributions for ADHD behaviors as less stable predicted teachers' greater satisfaction with the intervention techniques during the summer program and their greater attunement to children's social networks. Cognitions about the causes of children's ADHD behaviors held by preservice teachers may relate to their subsequent experiences with children in the context of implementing classroom behavioral management.
