It is argued that knowledge about models is an important part of a profound understanding of Nature of Science. Consequently, researchers have developed different "levels of understanding" to analyse students', teachers', or experts' comprehension of this topic. In some approaches, "global" levels of understanding have been…

The main purpose of this research was to investigate how Taiwanese grade 6 readers selected and used information from different print (main text, headings, captions) and visual elements (decorational, representational, interpretational) to comprehend a science text through tracking their eye movement behaviors. Six grade 6 students read a double…

In this study, we investigated how students used a drawing tool to visualize their ideas of chemical reaction processes. We interviewed 30 students using thinking-aloud and retrospective methods and provided them with a drawing tool. We identified four types of connections the students made as they used the tool: drawing on existing knowledge,…

A relatively quick, face-to-face, adaptive working memory training intervention was assessed in 5-to 8-year-old typically developing children, randomly allocated to a 6-week intervention condition, or an active control condition. All children received 18 sessions of 10?minutes, three times/week for 6?weeks. Assessments of six working memory…

Understanding conflicts between sources is an inherent part of science text comprehension. We examined whether readers' memories for conflicts and their situational interpretation of conflicts would be affected by reading goals and lexical cue phrases that signal rhetorical relationships. To this end, 198 undergraduates read multiple documents on…

Differing etiological explanations have been proposed to account for poor comprehenders' difficulties with reading comprehension, with some researchers emphasizing working memory deficits and others arguing for oral language weaknesses playing a key causal role. The authors contrasted these two theoretical accounts using data obtained from direct…

Our contribution to this special issue on reading theory questions the effectiveness of the prevailing interventions intended to improve word-reading and reading comprehension skills in children with reading disability (RD). Our hypothesis is that we as a field may have inadvertently diluted reading theory in ways that compromise the power of…

The purpose of this research was to build and test a conceptual model of the complex interrelationships between students' learning in science (learning approaches and self-regulation), their reading comprehension, question-asking in class and science achievement. These variables were measured by means of a test and a series of questionnaires…

This article make a case for the importance of background knowledge in children's comprehension. It suggests that differences in background knowledge may account for differences in understanding text for low- and middle-income children. It then describes strategies for building background knowledge in the age of common core standards.

This paper selects six key alternative conceptions identified in the literature on student understandings of chemical bonding and illustrates how a historical analysis and a textbook analysis can inform these conceptions and lead to recommendations for improving the teaching and learning of chemical bonding at the secondary school level. The…

In this article, teachers are reminded that their content subject areas require acquainting children with special words or symbols related to that subject area (e.g. mathematics or social studies). Because children can read well does not mean they would be understanding of any special reading skill required in a content subject area; that the…

This study used a Chinese-language version of the Index of Science Reading Awareness (ISRA) to investigate metacognitive awareness and the Reading Comprehension of Science Test (RCST) to explore comprehension of science text by Taiwanese students. Structural equation modeling (SEM) results confirmed the validity of the underlying models of…

Purpose: The purpose of this study was to examine the intelligibility of English consonants and vowels produced by Chinese-native (CN), and Korean-native (KN) students enrolled in American universities. Method: 16 English-native (EN), 32 CN, and 32 KN speakers participated in this study. The intelligibility of 16 American English consonants and 16…

The purpose of this study was to investigate the influence of goal specificity and scaffolding on the programming performance and self-regulation of elementary students engaged in learning game design. This study recruited 232 students for the experimental activities. Two levels of goal specificity were employed: specific and nonspecific.…

We identify and document 3 cognitive obstacles, 3 cognitive affordances, and 1 type of integer understanding that can function as either an obstacle or affordance for learners while they extend their numeric domains from whole numbers to include negative integers. In particular, we highlight 2 key subsets of integer reasoning: understanding or…
