Educators and several national standards highlight the role that problem solving should play in students' mathematics education: problem solving is recognized as one of the most significant activities of doing mathematics. From the research point of view, nowadays, it is well established that cognitive and affective factors come into play in…

Bilingualism appears to be related to poor language and reading comprehension in the instructional language (L2). However, in the long term, an early age of second language acquisition (AoA) may produce higher levels of second language skills than a later onset of L2 exposure. Most studies on school-aged second language learners (L2 learners)…

Reading prosody is considered one of the essential markers of reading fluency, alongside accuracy and speed. The aim of our study was to investigate how development of reading prosody in Spanish children varies with sentence type and length. We compared primary school children from the third and fifth grades with an adult sample. Participants were…

Purpose: This study examined the attitudes of Cypriot elementary school students toward physical education. Fourth, fifth and sixth grade students (N = 763) from six urban Cypriot elementary schools completed an attitude instrument. Methods: Adapting the attitude instrument for Greek-speaking students an extensive two-step pilot study showed the…

It is often discussed whether dyslexics show a deviant pattern of reading and spelling development when compared to typically developing students, or whether they follow the same pattern as other students, only at markedly slower rate. The present cross-sectional study investigated phonological encoding skills in dyslexic Danish students. We…

Many students' knowledge of fractions is adversely affected by whole number bias, the tendency to focus on the separate whole number components (numerator and denominator) of a fraction rather than on the fraction's magnitude (ratio of numerator to denominator). Although whole number bias appears early in the fraction learning process and under…

The current study examined the effects of grade level and object size on the ability to estimate the measurement of objects. Fifth- (n = 198) and sixth-grade (n = 208) students and freshman undergraduate students (n = 71) from Taipei city, Taiwan, participated in the study. The findings indicated a tendency for measurement estimation ability to…

This study set out to explore levels of religious affect (measured by the Francis Scale of Attitude toward Christianity) and personal affect (measured by the Oxford Happiness Questionnaire) among samples of Catholic students in the Republic of Ireland attending fifth- and sixth-year classes (N = 3015) and Catholic students in Northern Ireland…

Many students' knowledge of fractions is adversely affected by whole number bias, the tendency to focus on the separate whole number components (numerator and denominator) of a fraction rather than on the fraction's integrated magnitude (ratio of numerator to denominator). Although whole number bias appears early in the fraction learning process…

The present study examines instructional approaches and cognitive factors involved in elementary school children's thinking and learning the Control of Variables Strategy (CVS), a critical aspect of scientific reasoning. Previous research has identified several features related to effective instruction of CVS, including using a guided learning…

U.S. Department of Education data continually indicate that students who are English Learners (ELs) underperform in reading compared to students who are not English Learners (non-ELs). This study examined whether a personalized, adaptive blended learning approach can support reading development in ELs and non-ELs. There were 442 ELs and 442…

Social exclusion and the behaviors, thoughts, and feelings it evokes in children were examined in the present study. Two forms of exclusion were identified: being rejected and being ignored. Surveys were administered to third and fifth grade students in a Northeastern suburb in the United States to see how children respond overall and if younger…

The study aimed to extend current research on conditions that better support analogical encoding through mutual alignment. We focused on two variables that have not been examined independently in previous studies: the joint presentations of two cases of a scientific phenomenon and the explicit instructions for comparison. One hundred and…

This study examined the effectiveness of two instructional mind-mapping approaches to stimulate fifth and sixth graders' graphical summarization skills. Thirty-five fifth- and sixth-grade teachers and 644 students from 17 different elementary schools participated. A randomized quasi-experimental repeated-measures design was set up with two…

The psychometric qualities of the six- and eight-item implicit theories of intelligence scales that Dweck suggested were compared using a confirmatory factor analysis with data from 239 gifted students (100 students in Grades 5-7, 139 students in Grades 8-11). The results indicate that the six-item scale fits the data better than the eight-item…
