Success for All (SfA) is a comprehensive school reform program designed to support schools serving many students of disadvantaged backgrounds to increase students' achievement. SfA includes daily 90-min reading lessons with extensive use of cooperative learning, tutoring for struggling readers, and an emphasis on parental involvement. School teams…

The present study examined the psychometric properties of Student-Teacher Relationship Drawings (STRDs) to assess student-teacher relationship quality in a cross-cultural context. A sample of upper elementary school students from both the Netherlands (N = 752) and China (N = 574) was included. Results showed sufficient inter-rater reliabilities of…

Learning to solve subtraction problems that require borrowing (e.g., 83-57=) is challenging, and these problems often cause 'bridging' errors, such as the smaller-from-larger error. This study explores how bridging errors in subtraction are related to students' mathematical ability. The study involved 694 third-grade students and 35 teachers from…

In this study, we analyze in-depth interviews conducted with 26 Dutch third-graders as well as interviews with one of each child's parents. The children attended one of six schools, each with a relatively large population of families with a low socioeconomic status, where home-based literacy assignments aimed at increasing children's enjoyment of…

This study explored the relationships between task beliefs about the empty number line (ENL), mathematical ability, gender, and voluntary ENL use in multi-digit subtraction and addition. One hundred twenty-three Dutch third-grade students and nine teachers from six schools participated in this study. The multilevel path analysis showed that task…

Differentiation and achievement grouping are frequently implemented practices to adapt education to students' varying educational needs based on achievement level. Potential didactical and socioemotional advantages and disadvantages of these practices have been discussed in the literature. However, little is known about the perspective of students…

Central elements of adaptive expertise in arithmetic problem solving are flexibility, using multiple strategies, and adaptivity, selecting the optimal strategy. Research shows that the strategies children actually use do not fully reflect the strategies they know: there is hidden potential. In the current study a sample of 147 third graders from…

School closures due to the COVID-19 pandemic raised concerns about increases in educational inequality. We examined the magnitude of the impact of the first school closure for vulnerable student groups in particular. This study was conducted among 886 Grade 3-5 students in the Netherlands in schools serving a high percentage of students from…

This study investigated the impact of second language (L2) lexical quality on L2 reading comprehension in bilingual primary education. The participating children were taught in the L2 English for 30-50% of the time and the remaining time in their L1 Dutch. Seventy-three pupils from four different schools were assessed in the L2 on vocabulary,…

Stability is an important underlying assumption in any form of assessment-supported decision-making. Since early years development is frequently described as unstable, the concept plays a central role in the discussion surrounding early years assessment. This paper describes stability as a set of assumptions about the way individual scores change…

This paper discusses how primary school students, who are writing together in the context of inquiry learning, explicitly orient to knowing of oneself and others within the peer group. Using Conversation Analysis, we disclose the conversational functions of assertions holding 'I know', 'you know' and 'we know'. First, students position themselves…

The present study investigated responsiveness to intervention in children with an earlier versus later diagnosis of dyslexia. We examined differences between second (n=122; early diagnosis) and third (n=158; late diagnosis) graders with dyslexia on reading and spelling abilities before, during and after a dyslexia intervention as well as in…

This study aimed to shed light on the prevalence of chronic peer victimisation among Dutch elementary school children and factors associated with (non-)disclosure of such experiences by victims. 5,961 students from 73 schools participated (51.5% male; M[subscript age] = 9.96; 77.7% native Dutch). Results showed that 12.3% of all children were…

The relationship among students' reading performance, their behavior (task-focused behavior, emotional stability, and compliant behavior) in the classroom, and the teacher's skills was investigated in 66 third-grade classrooms. Results from this study showed the students' reading performance and their behavior in the classroom are all…

Children practice their spatial skills when playing with spatial toys, such as construction materials, board games, and puzzles. Sex and SES differences are observed in the engagement in such spatial play activities at home, which relate to individual differences in spatial performance. The current study investigated the effects of explicitly…
