Numerical Magnitude Representations and Individual Differences in Children's Arithmetic Strategy Use

Against the background of neuroimaging studies on how the brain processes numbers, there is now converging evidence that numerical magnitude representations are crucial for successful mathematics achievement. One major drawback of this research is that it mainly investigated mathematics performance as measured through general standardized achievement tests. We extended this research by investigating the association between numerical magnitude representations and children's strategy use during single‐digit arithmetic. Our findings reveal that children's symbolic but not nonsymbolic numerical magnitude processing skills are associated with individual differences in arithmetic. Children with better access to magnitude representations from symbolic digits retrieve more facts from their memory and are faster in executing fact retrieval as well as procedural strategies. These associations remain even when intellectual ability, digit naming, and general mathematics achievement are additionally controlled for. All this indicates that particularly the access to numerical meaning from Arabic symbols is key for children's arithmetic strategy development, which suggests that educators and remedial teachers should focus on connecting Arabic symbols to the quantities they represent.     

Effects of cooperation and feedback by fellow-pupils on spelling-achievement

In a field experiment among third grade pupils from 15 primary schools, three instruction methods were compared. At five schools (control condition) pupils did spelling exercises as usual, i. e. individually; at five other schools the pupils also worked individually, but checked each other’s work after which they had the opportunity to correct their own mistakes. At another five schools pupils worked in pairs. Each pupil had to check the other pupil’s work and discuss the mistakes. For the low achievers cooperation led to higher achievement than the individual working method. Pupils who checked each other’s work but did not cooperate did not show any more improvement than pupils who worked individually.     

Reading for meaning: the effects of Developmental Education on reading achievements of primary school students from low SES and ethnic minority families

The appropriateness of innovative educational concepts for students from a low socioeconomic status (SES) or ethnic minority background is sometimes called into question. Disadvantaged students are supposed to benefit more from traditional approaches with Programmatic Instruction (PI). We examined Developmental Education (DE), an innovative approach, inspired by Vygotskian theory, in which reading skills are developed through meaningful reading of texts corresponding to students’ self-generated problems. The effectiveness of DE is compared to PI in terms of reading comprehension, strategy knowledge, and reading motivation of 4th-grade students; 170 students from ethnic minority or low SES background participated in a pretest-posttest natural 2-group design. Outcomes were similar in both approaches, with one exception: Students with an ethnic minority background in DE performed better on strategy knowledge than similar students in PI. These results are discussed in relation to previous studies on the appropriateness of innovative curricula for disadvantaged students.     

Adaptive Behavior,Social Adjustment,and Academic Achievement of Regular and Special Education Children

The purpose of the present study was to compare the adaptive behavior, social adjustment and academic achievement of educable mentally retarded, learning disabled, behavior disordered, and regular class children. A sample of 120 children, aged 7 through 9 years, was selected from class rolls on the basis of group membership, race and sex. Significant differences were found in adaptive behavior, social adjustment, and academic achievement among the four groups; none of the instruments, however, was able to differentiate among all four categories of children. Adaptive behavior and academic achievement differentiated EMR and regular class children from the other two groups, while social adjustment appeared to be the most effective variable in differentiating BD children from the other three categories. Findings of this study support the notion that measures of these abilities provide information of use to teachers, psychologists, and placement committees in their attempts to provide the most appropriate and meaningful education for students with special needs.

The influence of 2 weeks of low-volume high-intensity interval training on health outcomes in adolescent boys

Abstract

The present study aimed to establish whether 2 weeks of high-intensity interval training would have a beneficial effect on aerobic fitness, fat oxidation, blood pressure and body mass index (BMI) in healthy adolescent boys. Ten adolescent boys (15.1 ± 0.3 years, 1.3 ± 0.2 years post-estimated peak height velocity) completed six sessions of Wingate-style high-intensity interval training over a 2-week period. The first session consisted of four sprints with training progressed to seven sprints in the final session. High-intensity interval training had a beneficial effect on maximal O₂ uptake (mean change, ±90% confidence intervals: 0.19 L · min^?1, ±0.19, respectively), on the O₂ uptake at the gas exchange threshold (0.09 L · min^?1, ±0.13) and on the O₂ cost of sub-maximal exercise (–0.04 L · min^?1, ±0.04). A beneficial effect on the contribution of lipid (0.06 g · min^?1, ±0.06) and carbohydrate (–0.23 g · min^?1, ±0.14) oxidation was observed during sub-maximal exercise, but not for the maximal rate of fat oxidation (0.04 g · min^?1, ±0.08). Systolic blood pressure (1 mmHg, ±4) and BMI (0.1 kg · m², ±0.1) were not altered following training. These data demonstrate that meaningful changes in health outcomes are possible in healthy adolescent boys after just six sessions of high-intensity interval training over a 2-week period.     

Beginning teachers’ self-efficacy and stress and the supposed effects of induction arrangements

Induction arrangements are implemented in schools all over the world to support beginning teachers (BTs) (novices) in gradually growing into their profession. The aim of this study is to gain more insight into two key psychological processes involved in the work of a qualified beginning teacher, namely perceived stress and self-efficacy. This unfolding is necessary to find a path of influence to lead the way to meaningful support interventions. Support in the form of induction arrangements is hypothesised to decrease perceived stress and to increase self-efficacy and, thus, decrease stress outcomes. To test our hypotheses 30 BTs and their school-based educators, working in 13 different schools, were surveyed. The analyses revealed that stress causes and stress outcomes are indeed interrelated and that self-efficacy affects this relationship in a mediating way. However, besides decreasing a beginning teachers’ perceived lack of learning opportunities, no other influences of induction arrangements were obtained. Implications and suggestions for future research are discussed.     

School Level Conditions Affecting the Effectiveness of Instruction

In this article, the current status of school level factors, as they appear in research reviews and in school effectiveness models is criticised both from a theoretical and from an empirical perspective. School level factors are often related to student achievement without taking into account the classroom level, where teaching and learning primarily take place. As a theoretical alternative, an overview of school level factors that enhance the quality of instruction, time for learning and opportunity to learn at the classroom level is provided. These factors are supposed to contribute to the explanation of differences in student achievement. Some empirical support for these ideas is found in educational research studies that have made use of three‐level analyses.
