Children's Vulnerability to Interparental Conflict: The Protective Role of Sibling Relationship Quality

This study tested whether the strength of the mediational pathway involving interparental conflict, adolescent emotional insecurity, and their psychological problems depended on the quality of their sibling relationships. Using a multimethod approach, 236 adolescents (M_age = 12.6 years) and their parents participated in three annual measurement occasions. Tests of moderated mediation revealed that indirect paths among interparental conflict, insecurity, and psychological problems were significant for teens with low, but not high, quality bonds with siblings. High-quality (i.e., strong) sibling relationships conferred protection by neutralizing interparental conflict as a precursor of increases in adolescent insecurity. Results did not vary as a function of the valence of sibling relationship properties, adolescent sex, or gender and age compositions of the dyad.     

Language Matters: Denying the Existence of the 30-Million-Word Gap Has Serious Consequences

Sperry, Sperry, and Miller (2018) aim to debunk what is called the 30-million-word gap by claiming that children from lower income households hear more speech than Hart and Risley (1995) reported. We address why the 30-million-word gap should not be abandoned, and the importance of retaining focus on the vital ingredient to language learning—quality speech directed to children rather than overheard speech, the focus of Sperry et al.'s argument. Three issues are addressed: Whether there is a language gap; the characteristics of speech that promote language development; and the importance of language in school achievement. There are serious risks to claims that low-income children, on average, hear sufficient, high-quality language relative to peers from higher income homes.     

Student satisfaction,teacher internships,and the case for a critical approach to international education

In recent times distinctions between the economic and political imperatives of international education and its cultural and educational aspects have become conveniently aligned. This alignment is troubling because it allows the pursuit of profit to fit neatly and without apparent controversy into the pursuit of more lofty political cultural and educational goals. Measures of student satisfaction with international education do little to challenge this comfortable affiliation. Indeed, they appear to reinforce the view that international education as currently pursued is travelling well and yielding maximum profits and benefits for all. The discussion in this article is based on the results of a pilot study that examined international student satisfaction with a teacher education internship program in Australia. Our findings showed that students were satisfied with their international education experience and that the internship/work integrated learning experience enhanced their satisfaction. Importantly however, our pre-departure study showed that students expected study abroad to make a difference to their lives even before they left home. The study led us to consider the meaning of student satisfaction and whether assessments of satisfaction might simply confirm what students already expect. If this is the case, it is not altogether clear what student satisfaction with international education means or measures.     

Self‐Regulation and Mathematics Instruction

Abstract The purpose of this article is to provide an overview of research‐based interventions that incorporate self‐regulation strategies to improve mathematics performance of students with learning disabilities (LD). Self‐regulation is a metacognitive function essential to academic success. Students with LD are notoriously poor at self‐regulation and must be taught explicitly to monitor and control their cognitive activities as they engage in academic tasks such as mathematical problem solving. This article describes intervention studies that use self‐regulation strategies to improve mathematics performance of students with LD at the elementary, middle, and secondary school levels. Several techniques to facilitate effective implementation of self‐regulation instruction in the classroom are presented.     

Effects of pomegranate extract on blood flow and vessel diameter after high-intensity exercise in young,healthy adults

The effects of pomegranate extract (PE) supplementation were evaluated on high-intensity exercise performance, blood flow, vessel diameter, oxygen saturation (SPO₂), heart rate (HR), and blood pressure (BP). In a randomized, crossover design, nineteen recreationally resistance-trained participants were randomly assigned to PE (1000?mg) or placebo (PL), which were consumed 30?min prior to a repeated sprint ability (RSA) test and repetitions to fatigue (RTF) on bench and leg press. The RSA consisted of ten six-second sprints on a friction-loaded cycle ergometer with 30?s recovery. Brachial artery blood flow and vessel diameter were assessed by ultrasound. Blood flow, vessel diameter, SPO₂, HR, and BP were assessed at baseline, 30?min post ingestion, immediately post exercise (IPost), and 30?min post exercise (30minPost). With PE, blood flow significantly increased IPost RSA (mean difference?=?18.49?mL?min^?1; P?<?.05), and IPost and 30minPost RTF (P?<?.05) according to confidence intervals (CI). Vessel diameter increased significantly 30minPost RSA according to CI and resulted in a significant interaction IPost and 30minPost RTF (P?<?.05). With PE, according to CI, average and peak power output increased significantly in sprint 5 of the RSA (P?<?.05). There was no significant difference between PE and PL for bench (P?=?.25) or leg press (P?=?.15) repetitions. Acute PE supplementation enhanced vessel diameter and blood flow, suggesting possible exercise performance enhancement from increased delivery of substrates and oxygen. The acute timing and capsule form of PE may be advantageous to athletic populations due to ergogenic effects, taste, and convenience.     

Transition to Science Teacher Educator: Tensions Experienced while Learning to Teach Lesson Sequencing

This self-study investigated the tensions that I (Heidi) encountered when teaching elementary preservice teachers how to develop a coherent sequence of five science lessons. Four lesson planning components guided me in developing a series of lessons to support the preservice teachers with this exercise. Employing self-study methodology, data sources included preservice teachers' artifacts, an audio-recording of the preservice teachers discussing the planning of their lesson sequence, and two reflection journals, one kept personally and one kept collaboratively with my co-author and critical friend (Meredith). Findings indicate that a tension of telling and growth developed gradually during the three weeks of teaching. The collaborative journal revealed that this tension was promoted by two other tensions: confidence and uncertainty, and planning and being responsive. Implications regarding the need for explicit teacher educator coursework and reflective practice opportunities are discussed as potential avenues for Ph.D. programs to consider to lessen the tensions that doctoral students may experience during their transition into the role of teacher educator.     

Who am I and where do I belong? The perception and evaluation of teacher leaders concerning teacher leadership practices and micropolitics in schools

The phenomenon of teachers taking on leadership tasks beyond their classroom duties has become widespread internationally. While presented as a catalyst for educational improvement, it blurs the traditional division between teaching and leading and therefore challenges the conventional professional relationships in schools as well as the professional self-understanding of teacher leaders. This article reports on an exploratory study of the perceptions of teacher leaders in Flemish primary and secondary schools. By conducting semi-structured interviews of 26 teacher leaders, we collected data concerning their tasks and the consequences for both their social–professional relations with teacher colleagues and school leaders and their professional self-understanding. From a micro-political perspective, the results demonstrate how teacher leadership introduces new structures of interactions in schools that makes teacher leaders find themselves continuously juggling between two different agendas of professional interests: obtaining recognition as a teacher leader by their colleagues as well as maintaining their social–professional relationships with their colleagues.
