A review of Catherine Milne��s book, The Invention of Science

Catherine Milne’s book, The Invention of Science, recounts the history of science (mainly Eurocentric) from cross-cultural, historical and philosophical worldviews. Scientists, science educators, and teachers would find this an interesting book, not only for themselves but also for those with whom they interact. Most accounts are of the great men in science with some to women in science, including reference to the exclusion of women from science. Milne provides thought-provoking activities to use in the classroom, like asking students to write the processes that occur when sugar dissolves in hot tea, with students including the three components of causal explanation. She also encourages teachers to use narratives to help students learn the context of discovery in science. In a comparison of analogical, deductive, inductive and abductive reasoning, she encourages teachers to pay attention to dialogical arguments. Book review author predicts that Milne’s book will fit well with the nation’s next generation science standards, still in development form. Milne succeeded in her goal “to combine aspects of the philosophy and history; not just to focus on specific scientific ideas but to provide a hint of the complex relationship between place and history, space and time, in the development of Eurocentric science.”     

Responding to students’ views about university teaching: the experience of teachers in Jamaica

Individual consultation over student ratings is recognised as an effective strategy to improve teaching effectiveness. Yet limited financial resources and rising costs in higher education renders this strategy as no longer feasible. This paper explores teacher perceptions on the efficacy of a peer-based model of consultation. It draws on a randomised controlled trial with university teachers discussing their ratings feedback with disciplinary peers. The findings indicated that teachers were receptive towards the idea of collaborating to learn from student ratings how to improve their teaching. The model should be refined with continued research.     

Reliability and validity of depth camera 3D scanning to determine thigh volume

Gross thigh volume is a key anthropometric variable to predict sport performance and health. Currently, it is either estimated by using the frustum method, which is prone to high inter-and intra-observer error, or using medical imaging, which is expensive and time consuming. Depth camera 3D-imaging systems offer a cheap alternative to measure thigh volume but no between-session reliability or comparison to medical imaging has been made. This experiment established between-session reliability and examined agreement with magnetic resonance imaging (MRI). Forty-eight male cyclists had their thigh volume measured by the depth camera system on two occasions to establish between-session reliability. A subset of 32 participants also had lower body MRIs, through which agreement between the depth camera system and MRI was established. The results showed low between-session variability (CV = 1.7%; Absolute Typical Error = 112 cm³) when measuring thigh volume using the depth camera system. The depth camera systematically measured gross thigh volume 32.6cm³ lower than MRI. These results suggest that depth camera 3D-imaging systems are reliable tools for measuring thigh volume and show good agreement with MRI scanners, providing a cheap and time-saving alternative to medical imaging analysis.     

The Effect of Early Intervention Services on Maternal Well-Being

In this investigation we examine the relation between intensity, duration, and comprehensiveness of early intervention (EI) services and changes in three aspects of maternal well-being: parenting stress, social support, and family cohesion. Data on the hours, length, and types of services received by a sample of 133 children and families from EI programs in Massachusetts and New Hampshire were gathered from the point of entry into EI to the point of discharge around the child's third birthday. Hierarchical regression analyses were used to determine which measure of EI service intervention contributed significantly to the explained variance in changes in maternal well-being, over and above aspects of the child's functioning and prior levels of maternal well-being. Results indicated that, although greater service intensity was associated with improved family cohesion overall, mothers of children without motor impairment reported greater increases than mothers of children with motor impairment. Service intensity and comprehensiveness predicted significant increases in social support levels. EI services did not have a significant impact on parenting stress. Three practice and policy implications are discussed: building flexibility into EI service provision to be responsive to individual family needs; attending to the accommodations required of families raising a child with a motor impairment; and incorporating other aspects of family functioning into future studies of EI effectiveness.     

Patterns of word and nonword processing in skilled and less-skilled readers

Sixty-eight third graders who were less-skilled readers performed more poorly than younger reading-level control children on tests of pseudoword reading and phonological sensitivity. These findings add to the growing consensus that the proximal cause of reading difficulties are spelling-sound coding problems that result from deficient underlying phonological processes and structures. Analyses of their word and pseudoword reading performance provided some suggestive evidence that less-skilled readers are less sensitive than their younger reading-level matched counterparts to all subword-size orthographic units, perhaps especially to grapheme-sized units.

Academic vocabulary and middle school English learners: an intervention study

The goal of this experimental intervention study was to determine if evidence-based instructional strategies for general vocabulary words are effective with middle school English learner (EL) students and academic vocabulary words. Participants showed significantly more growth in their knowledge of academic vocabulary during the treatment condition than during the control condition. A secondary goal of this study was to examine the predictive utility of students’ English language proficiency, and students’ general vocabulary knowledge in English was a positive predictor for their academic vocabulary growth during the intervention. However, participants’ growth during the control period had the greatest predictive utility for their growth during the intervention. Furthermore, this relationship was negative, suggesting that the intervention had the greatest benefits for students who made the least progress in English vocabulary in the absence of the intervention. Implications for instruction, policy, and future research are presented.

The past in the present: historicising contemporary debates about gender and education

History is often embedded, explicitly or implicitly, in discourses on contemporary aspects of gender and education, but relatively few scholars engage critically with history as they grapple with current issues. This article posits ‘historical sensibility’ as a means of engaging constructively with the past when scrutinising and working on current issues in gender and education. Four features of historical sensibility are mapped out and compared with established ways of approaching the relationship between the present and past. The utility of historical sensibility is demonstrated with reference to ongoing debates about the feminisation of schooling, the sexualisation of children and the leisure pursuits of young women.
