Teacher–student interaction in contemporary science classrooms: is participation still a question of gender?†

We show that boys still have a greater access to the space for interaction in science classrooms, which is unexpected since in Sweden today girls perform better in these subjects than boys. Results from video-recorded verbal communication, referred to here as interaction, show that the distribution of teacher–student interaction in the final year of lower secondary school follows the same patterns as in the 1980s. The interaction space for all kinds of talk continues to be distributed according to the two-thirds rule for communication in science classrooms as described by previous research. We also show that the overall interaction space in science classrooms has increased for both boys and girls when talk about science alone is considered. Another finding which follows old patterns is that male teachers still address boys more often than girls. This holds true both for general talk and for talk about science. If a more even distribution of teacher–student interaction is desirable, these results once again need to be considered. More research needs to be undertaken before the association between girls’ attitudes and interest in science in terms of future career choice and the opportunity to participate in teacher–student interaction is more clearly understood.     

True and false memories in maltreated children

Differences in basic memory processes between maltreated and nonmaltreated children were examined in an experiment in which middle-socioeconomic-status (SES; N = 60), low-SES maltreated (N = 48), and low-SES nonmaltreated (N = 51) children (ages 5-7, 8-9, and 10-12 years) studied 12 Deese-Roediger-McDermott lists. Using recall and recognition measures, the results showed that both true and false memories increased with age and, contrary to some speculation, these trends did not differ as a function of maltreatment status. However, there were differences in overall memory performance as a function of SES. These results are discussed in the broader framework of children's memory development and the effects of the chronic stress associated with child maltreatment on basic memory processes.     

Impairments in learning due to motivational conflict: situation really matters

Although many theories mention distractions by conflicting alternatives as a problem for self-regulation, motivational conflicts are rarely considered when explaining impairments in learning. In two studies, we investigate the assumption of motivational interference theory that students show different amounts of impairments in learning depending on the presence and motivational strength of conflicting alternatives. In Study 1 (N?=?221), the subjective value attributed to a respective alternative in a study–leisure conflict scenario partially accounted for differences in self-regulated learning while controlling for interindividual differences. Study 2 (N?=?112) demonstrated that this pattern applies to both when the respective alternatives refer to ‘liking to’ (want conflicts) and ‘having to’ (should conflicts) do something. Moreover, it is demonstrated that impairments due to motivational conflict are higher than impairments inherent in the studying activity itself (baseline). The results emphasise the importance of concurring action alternatives for explaining difficulties in self-regulated learning.

Early numeracy in low‐performing young children

The aim of this study was to explore the early numeracy of low‐performing young children. The mean age of the children was six years and four months. The 511 participants belonged to three groups: multi‐language children, children with special educational needs and children with average performance. The results showed that there were significant group differences in early numeracy: the children in the reference group had better relational and counting skills than those with a multi‐language background and those with special educational needs. Some differences were found in counting skills between the children with multi‐language background and those with special educational needs. Finally, (special) educational support for low‐performing children is discussed.     

Establishing a practical treadmill sprint as an alternative to the Wingate anaerobic test

This study examined the validity and reliability of a 30-second running sprint test using two non-motorized treadmills compared to the established Wingate Anaerobic Test. Twenty-four participants completed three sessions in a randomized order on a: (1) manual mode treadmill (Woodway); (2) specialized interval training treadmill (HiTrainer); and (3) Wingate cycle ergometer. In a subset of 15 participants, 2 additional sessions were completed on both treadmills to establish the test–retest reliability. Peak (Woodway: r = .68; HiTrainer: r = .58; p < .003), average (Woodway: r = .82; HiTrainer: r = .72, p < .001), and minimum (Woodway: r = .64; HiTrainer: r = .42, p < .043) speed indices were moderately to very strongly correlated with corresponding Wingate Anaerobic Test outputs and had excellent test–retest reliability (all intraclass correlation coefficients > .75). Fatigue index during the Wingate Anaerobic Test (51.20 ± 7.14%) was moderately correlated with the Woodway (32.9 ± 10.9%, r = .55, p = .005) only. This 30-second running sprint test may be a valid and reliable mode-specific alternative to the Wingate Anaerobic Test.     

The Impact of a Therapy Dog Program on Children’s Reading: Follow-up and Extension to ELL Students

An initiative in which therapy dogs were integrated into a school-wide reading curriculum was analyzed to determine the effect on student reading in the program’s second year. Prior research on the first year of this specific program (Kirnan et al. in Early Child Educ J 44(6):637–651) demonstrated improvement in reading scores only for kindergarten students, while interview data revealed increases in positive attitudes and enthusiasm for reading across all grades. In the current study, a series of independent t-tests were conducted for each grade, comparing the second year of the program to a control group. There was a significant difference for kindergarten in the second year, as reading scores were higher for program students compared to those in the control group. Unlike the first year of the program, in the second year there was also a significant mean difference in first grade. For both grades, an analysis of covariance controlling for reading scores prior to program implementation still resulted in a significant main effect for the reading program. Combining the first 2 years of the program yielded a large enough sample for a comparison of ELL students with non-ELL students in kindergarten. These data showed significantly higher reading scores for students enrolled in the dog program relative to the control for both ELL and non-ELL students, again accounting for earlier reading scores. These findings demonstrate the need to analyze at-risk subgroups as well as the need to apply a longitudinal lens in researching both dog-assisted literacy programs and participant progress.     

高校学生党员在学风建设中作用发挥机制研究

学风建设是高校提高教育教学质量的根本保证,是高校加快建设和不断发展的重要基础.搞好高校学风建设要充分发挥学生在学风建设过程中的主体作用,要高度重视学生党员在学风建设过程中的作用发挥.学生党员是推动学风建设的主力军,是培养优良学风的有力抓手.要在实践中不断健全机制,形成充分调动学生党员在学风建设中的主动性、积极性和创造性的机制,争取促进学生党建工作和高校学风建设,不断推动高等教育健康快速发展.     

低碳发展方案编制指南(第三部分)——制定低碳发展规划

本节介绍制定低碳发展计划常用的核心步骤。本指南侧重城市层面;同样的步骤也适用于企业、市、省和国家等层级。中国自"十一五规划"起,对改善国内能源强度定出目标,包括各经济部门的节能目标。2009年12月中国政府公布了其碳强度目标,重点放在单位GDP用能引发的二氧化碳排放量。为实现该强度目标以及"循环经济"等经济性目标,制定低碳发展规划尤其必要。
