Prior short-term studies have shown the effectiveness of worked examples and self-explanation prompts in improving elementary students' mathematics knowledge. However, year-long classroom-based interventions have been tested only with older students. The purpose of the current study was to explore the effectiveness of a year-long classroom…

Students' prior achievements in school have significant correlations with their later achievements. Specifically, students' prior numeracy achievement is the most important predictor of later numeracy success. However, the assessment of this predictor across gender and its trend across students' year levels is often overlooked or not adequately…

While existing studies have underscored the educational benefits of generating explanatory hypotheses (EHs) in response to unexpected outcomes, empirical research on the underlying mechanisms driving their effectiveness in science learning remains limited. Thus, this study aimed to empirically examine the effectiveness of generating an EH for…

Recent work has demonstrated that having students study worked examples and answer self-explanation prompts as part of their problem-solving practice improves learning on researcher-developed measures of mathematical proficiency. However, little work has been done to date to investigate whether these benefits translate to improvements on the types…

State-mandated tests have taken center stage for assessing student learning and for holding teachers and students accountable for achieving adequate progress. What types of early knowledge predict performance on these tests, especially among low-income children who are at risk for poor performance? We report on a longitudinal study of 519…

The two studies reported on in this paper examine the features of words that distinguish students' performances on vocabulary assessments as a means of understanding what contributes to the ease or difficulty of vocabulary knowledge. The two studies differ in the type of assessment, the types of words that were studied, and the grade levels and…

Words can be informative linguistic markers of psychological constructs. The purpose of this study is to examine associations between word use and the process of making meaningful connections to a text while reading (i.e., inference generation). To achieve this purpose, think-aloud data from third-fifth grade students (N = 218) reading narrative…

Previous studies (Collins, 2015; Kennan & Meenan, 2014) have shown how variations in text and task factors and individual reader skills affect performance on reading comprehension assessments. The present study examined whether different presentation conditions (silent reading, watching a video) and response formats (open-ended vs.…

This study was conducted to examine the factors that influence informational text comprehension and to determine how these vary for students with higher and lower component skills. The sample included 177 students in grades 3-5. Regression analyses were used to predict informational text comprehension with decoding efficiency, vocabulary…

Modern knowledge-based societies, especially their younger members, have largely lost their bonds to farming. However, learning about agriculture and its interrelations with environmental issues may be facilitated by students' individual interests in agriculture. To date, an adequate instrument to investigate agricultural interests has been…

This study investigates the capacity of children to develop map-based skills in spatial orientation in an urban environment unknown to them. In this quantitative study, a total of 328 pupils of grades 3-5 had to achieve specific skills with regard to map-based skills in spatial orientation (such as turning-off skills, transformation from map to…

Previous research has identified various factors that contribute to readers' comprehension of expository texts, including strategy expertise, language proficiency, prior knowledge, and more recently, readers' beliefs about knowledge. This study addresses the need to understand the relative contributions of these predictors to readers'…

This purpose of this study was to develop a clearer understanding of the complex, interrelated factors that lead to successful informational text comprehension and to determine if or how these factors vary for higher and lower comprehenders. Participants (N = 177) were in grades three through five and were predominately African American (61%) and…
