Baby carriage: infants walking with loads

Maintaining balance is a central problem for new walkers. To examine how infants cope with the additional balance control problems induced by load carriage, 14-month-olds were loaded with 15% of their body weight in shoulder-packs. Both symmetrical and asymmetrical loads disrupted alternating gait patterns and caused less mature footfall patterns. Walking was most severely compromised by back loads. Infants with less walking experience, lower levels of walking proficiency, and chubbier body proportions were more adversely affected. In addition, infants displayed a unique postural response to asymmetrical loads. In contrast to older children and adults, infants leaned with loads rather than in the opposite direction to the loads. Findings are discussed in terms of development from accommodation to compensatory strategies.     

Bounded decision-making,teachers’ reflection and organisational learning: How research can inform teachers and teaching

Despite numerous efforts to align educational practice more closely with findings from educational research, there is little clarity about how educational practitioners can, in principle, use research. We propose a conceptualisation based on how research can contribute to practitioners’ thinking: specifically, our framework proposes that research can inform bounded decision-making, teachers’ reflection and organisational learning. Practitioners can also use research without being aware that they are doing so. We argue that this conceptualisation of research use has potential to inform researchers and practitioners.     

The Simple View of Reading: Is It Valid for Different Types of Alphabetic Orthographies?

We present a meta-analysis to test the validity of the Simple View of Reading Gough & Tunmer (Remedial and Special Education, 7:6–10, 1986) for beginner readers of English and other, more transparent, orthographies. Our meta-analytic approach established that the relative influence of decoding and linguistic comprehension on reading comprehension is different for readers of different types of orthography during the course of early reading development. Furthermore, we identified key differences in the relations among different measures of decoding and reading comprehension between readers of English and other more transparent orthographies. We discuss the implications for reading instruction and the diagnosis of reading difficulties, as well as our theoretical understanding of how component skills influence reading comprehension level.

A self-determination approach to understanding students' motivation in project work

The use of project work (PW) or project-based learning has escalated in Singapore since its inception by the Ministry of Education in the year 2000. There is however little information on students' motivation, and their experience of PW over time. This study sought to identify homogeneous groups of students with distinct perceived locus of causality (PLOC) profiles using a cluster analytic approach, and to examine group differences in their perceived psychological needs, emotions, metacognition, and perceived skills learned in PW over time. Four distinct clusters of students were identified. The “high self-determined/low controlled” group was the most adaptive cluster, and the “low self-determined/high controlled” group was the least adaptive cluster. The study affirms that the self-determination theory (SDT) can provide important insights into the motivational processes in PW. It establishes that students' motivational regulations and their perceived needs satisfaction at the start of PW are related to their experience of and learning in PW.     

Early narrative skills in Chilean preschool: Questions scaffold the production of coherent narratives

This study examined whether or not question answering aided the construction of coherent narratives in pre-readers. Sixty Chilean preschoolers completed two tasks using a wordless picture-book: 30 children answered questions about the story and then produced a narrative using the book; 30 children completed the tasks in reverse order. Elements of coherence were assessed in both tasks, namely problem, resolution, and mental-states. The findings indicate that questions can scaffold the production of more coherent narratives. Narratives elicited after questions were judged to be more coherent than those produced before the question–answering task. In contrast, there were no differences between scores for the question answers in the different order conditions. The results are discussed regarding the interactional role of questions and the facilitative effect they have on focusing attention to the narrative task.     

Understanding of Idiomatic Expressions in Context in Skilled and Less Skilled Comprehenders: Online Processing and Interpretation

This article reports a study in which good and poor comprehenders (in 2 age groups: 8- and 10-year-olds) read short passages containing phrases that could be interpreted as idiomatic or not, depending on the context. Familiarity was manipulated by including real (English) idioms and novel (translations of Italian) idioms. Reading times for the target phrases were measured and the children’s understanding of the target expressions was assessed. The older children and better comprehenders were more likely to interpret idiomatic phrases correctly. In particular, there was an interaction between age and meaning condition: The younger children were less able to choose an appropriate interpretation of the figurative expressions. In general, children spent relatively more time reading the idiomatic expressions than the literal ones, with the exception of less skilled comprehenders when presented with novel (Italian) idioms. They seemed not to appreciate that these expressions needed any particular effort for interpretation.
