Beginning readers' use of ‘talking books’ software can affect their reading strategies

This paper reports on a small‐scale study that considered whether a phonic‐based ‘talking book’ could outperform one‐to‐one reading tuition with an adult with respect to improving beginning readers' phonological awareness over a short period. It also examined whether the children's reading strategies were affected by their use of the software. Two groups of children, one aged five years and one aged six years, used three phonic‐based talking books over six 15‐minute sessions and were assessed on their phonological awareness and reading strategies both before and after this intervention. Their performance was compared to that of matched comparison groups who were given one‐to‐one adult tutoring with the paper versions of the same books. There were no significant differences between the two groups in their phonological awareness attainment, with both groups showing equivalent gains from pre‐ to post‐test. Use of specific features of the software was associated with gains in rhyme detection ability and with changes in the children's reading strategies.     

The role and effects of teaching assistants in English primary schools (Years 4 to 6) 2000–2003. Results from the Class Size and Pupil—Adult Ratios (CSPAR) KS2 Project

It is widely assumed that increasing the number of teaching assistants (TAs) in the classroom will be beneficial to children, and this is one important aim of the recently implemented Workforce Agreement. But there are still significant gaps in knowledge about many aspects of their deployment and impact. The Class Size and Pupil—Adult Ratios (CSPAR) KS2 study built on earlier findings when the pupils were in reception and Key Stage (KS) 1, and investigated: (1) the deployment of TAs in classrooms and how key parties involved perceived this; and (2) the effect of TAs on interactions involving pupils and teachers in the same classrooms, and on pupil attainments. The study had a longitudinal, mixed method and multi‐informant design. Methods of data collection included: (for the whole sample) questionnaires completed by TAs, teachers and head teachers, assessments of pupil attainments in mathematics, English and science, data on pupil background, and (for a sub‐sample) case studies and a systematic observation study. This study found that the TA's role in KS2 is predominantly a direct one, in the sense of face‐to‐face interactions supporting certain pupils. There was no evidence that the presence of TAs, or any characteristic of TAs, had a measurable effect on pupil attainment. However, results were clear in showing that TAs had an indirect effect on teaching, e.g. pupils had a more active form of interaction with the teacher and there was more individualised teacher attention. This supported teachers' views that TAs are effective in supporting them in this way. The authors conclude that more attention needs to be paid to what they call the pedagogical role of TAs so that they can be used effectively to help teachers and pupils, particularly in the context of the enhanced roles for TAs being introduced as part of the Government's remodelling agenda.     

The effect of β-alanine supplementation on cycling time trials of different length

The varying results reported in response to β-alanine supplementation may be related to the duration and nature of the exercise protocol employed. We investigated the effects of β-alanine supplementation on a wide range of cycling performance tests in order to produce a clear concise set of criteria for its efficacy. Fourteen trained cyclists (Age?=?24.8?±?6.7?years; VO_2max?=?65.4?±?10.2 mL·kg·min^?1) participated in this placebo-controlled, double-blind study. Prior to supplementation, subjects completed two (familiarization and baseline) supramaximal cycling bouts until exhaustion (120% pre-supplementation VO_2max) and two 1-, 4- and 10-km cycling time trial (TT). Subjects then supplemented orally for 4 weeks with 6.4?g/d placebo or β-alanine and repeated the battery of performance tests. Blood lactate was measured pre-exercise, post-exercise and 5 min post-exercise. β-alanine supplementation elicited significant increases in time to exhaustion (TTE) (17.6?±?11.5 s; p?=?0.013, effect compared with placebo) and was likely to be beneficial to 4-km TT performance time (?7.8?±?8.1 s; 94% likelihood), despite not being statistically different (p?=?0.060). Performance times in the 1- and 10-km TT were not affected by treatment. For the highly trained cyclists in the current study, β-alanine supplementation significantly extended supramaximal cycling TTE and may have provided a worthwhile improvement to 4-km TT performance. However, 1- and 10-km cycling TT performance appears to be unaffected by β-alanine supplementation.     

The fluid and electrolyte balance of New Zealand European and Māori/Pacific Island athletes: An observational study

Observational research on professional athletes from the USA suggests differences may exist in sweat sodium loss based on ethnic differences. The New Zealand (NZ) sporting population is mainly of European or Māori/Pacific Island origin. Therefore, this study aimed to describe the fluid-electrolyte balance of athletes by ethnicity. A total of 20 Māori/Pacific Islanders (MP; body mass 100.97 ± 13.05 kg) and 29 NZ European (NZE; body mass 89.11 ± 11.56 kg) elite male athletes were recruited. Sweat rates were determined by body mass change during a 1-h spin cycle exercise session, during which fluid intakes and heart rate were recorded. Sweat samples were analysed for sodium concentration. Mean ± SD sweat sodium concentrations were 73.4 ± 27.2 mmol·L^?1 and 55.5 ± 26.8 mmol·L^?1 for the MP and NZE groups, respectively (p = 0.070). Sweat rate was 0.93 ± 0.26 L·h^?1 for the MP group and 0.89 ± 0.33 L·h^?1 for the NZE group (p = 0.357). Fluid intake was 1.05 ± 0.48 L and 0.93 ± 0.49 L for MP and NZE, respectively (p = 0.395). Half of the MP group gained weight during the exercise session compared to 37% of the NZE group. Pre-exercise urine specific gravity was significantly lower amongst the NZE group (1.016 ± 0.009 g mL^?1) than the MP group (1.024 ± 0.008 g mL^?1) p = 0.001. There was no significant difference in heart rate between the groups, p = 0.082. Hydration practices of athletes in NZ may differ by ethnicity, and this may highlight the need for more targeted education by ethnicity.     

Interactive learning and technology in the US science and mathematics reform movement

This article presents an overview of the science/mathematics reform movement in the secondary/elementary schools and higher education institutions of the United States. It describes the research and views of educational practitioners regarding the need for change, as well as the particular changes which appear to be required. Emphasis is placed on the roles of interactive learning and technology in meeting reform goals.
Details of a recently completed curricular innovation project in science and mathematics are provided. Funded by the National Science Foundation, the project brought five faculty in the natural sciences together with a learning theorist at Florida Community College at Jacksonville, a large, multi-campus, public institution. The group developed and taught two basic integrated science/mathematics courses in which cooperative and discovery learning, supported by multimedia technology and distance learning, were major components. Details of results are provided as they relate to meeting the goals of the reform movement.     

Creative curriculum: Teaching self-awareness in a day care system

Conclusion It has been several years since I began our center, and as my understanding about self-awareness has become more sophisticated, I have enlarged on the development of the Concept Center ideas. I am now designing a general day care curriculum based on these ideas, because I think it is vital to approach all aspects of the child's development, that is, motor skills, readiness skills, cognitive / intellectual / perceptual skills, readiness skills, language skills, social and emotional skills, from the core of growth which is self-awareness.As teachers we are guides to the adventurous journey of life. Difficult, draining as it is, I think it is a real privilege to act as such guides to the bright and innocent young humans we work with in day care, who are so vigorously acquiring the fluency they need to participate in this life. With a little recognition, support and belief, we have the opportunity to provide the foundation for the development of extraordinary human beings. In doing this we contribute to a more healthful human community. Seen in this area day care is a moveable feast of rich energy and growth. All small contributions to this end mean a future sparkling with promise for our young children of today. I believe it is through tools like the Concept Center that we can begin to make them such a promise.     

Exploring learning goals and assessment approaches for Indigenous health education: a qualitative study in Australia and New Zealand

In higher education, assessment is key to student learning. Assessments which promote critical thinking necessary for sustained learning beyond university are highly valued. However, the design of assessment tasks to achieve these types of thinking skills and dispositions to act in professional practice has received little attention. This research examines how academics design assessment to achieve these learning goals in Indigenous health education. Indigenous health education is an important area of learning for health practitioners to help address worldwide patterns of health inequities that exist for Indigenous people. We used a constructivist qualitative methodology to (i) explore learning goals and assessment strategies used in Indigenous health tertiary education and (ii) examine how they relate to higher education assessment ideals. Forty-one academics (from nine health disciplines) involved in teaching Indigenous health content participated in a semi-structured interview. Thematic analysis revealed learning goals to transform students’ perspectives and capacities to think critically and creatively about their role in Indigenous health. In contrast, assessment tasks encouraged more narrowly bounded thinking to analyse information about historical and socio-cultural factors contributing to Indigenous health. To transform students to be critical health practitioners capable of working and collaborating with Indigenous people to advance their health and well-being, the findings suggest that assessment may need to be nested across many aspects of the curriculum using a programmatic approach, and with a focus on learning to think and act for future practice. These findings accord with more recent calls for transformation of learning and assessment in health education.
