Motivational Profile and Academic Achievement Among Students Enrolled in Different Schooling Tracks

From the contextual perspective, researchers argue that the relevance and weight of motivational variables of students' functioning vary depending on different dimensions related to individual, cultural or situational characteristics. The first objective of this study examined this contention by comparing self-perceptions of competence, learning goals and judgments of usefulness of school subjects as motivational determinants of high school students' commitment and achievement according to their assignment to their learning abilities. The second objective was to compare how these variables related to academic commitment and achievement according to the type of student and two school subjects. Two-hundred-and-twenty-six high school students from a same school participated sixty-one were learning disabled students, 60 were high achievers and 105 were average students. Findings suggest that the relevance of the motivational variables did not vary much across either the type of student or the school subjects. They also support Bandura's view about the primary role of self-perceptions of competence in students' academic commitment and achievement.     

Utilising creative methodologies to elicit the views of young learners with additional needs in literacy

The research described in this article aimed to explore and examine the dominant ‘assessment’ and ‘participation’ stories of upper‐primary pupils with long‐standing and marked literacy learning needs, their views on how their level of participation in the assessment and remediation of their additional needs might be increased and also how they perceive themselves as literacy learners. This qualitative small‐scale study adopted a case study approach and utilised creative methodologies in the context of focus groups to investigate sensitively the views and experiences of Key Stage 2 pupils with additional needs in literacy. The findings discussed here are based on the outcomes from the four Northern Irish schools that participated in the original cross‐border (Northern Ireland/Republic of Ireland) study. Findings are discussed in the context of strategies for promoting holistic and empowering pathways for learners with additional needs in literacy.     

Bologna in Context: a horizontal perspective on the dynamics of governance sites for a Europe of Knowledge

This article presents a horizontal perspective on the dynamics of governance sites currently active for the European of Knowledge and places the Bologna process in this wider European level context. It introduces two dynamics of change in political organisation: a) institutional differentiation and specialisation and b) the interaction between institutional spheres and sectors. Signs of sectoral differentiation are identified in the history of European integration that is relevant to the Europe of Knowledge. The argument is that the nature and sequence of the differentiation process are key to understand current governance processes. It is illustrated by showing how a horizontal dynamics has been played out in the case of the EU's Lisbon strategy and in particular the cooperation taking place in the framework of the EU's “Education and Training 2010” work programme. The analysis shows how the Bologna process, although perpetuated as a sector internal governance site, has co-evolved and interacted with this strategy, partly as an object of emulation and source of support and partly as a competing governance site. A horizontal dynamics of change is also evident in the larger Lisbon strategy as it lifted research and higher education policy to the centre of the European integration project. It resulted in the development of several governance sites with different foci targeting European higher education. A more prominent place on the political agenda came together with demands that research and education should be integrated with the overall political and economic objectives of the EU.     

Evaluating the teaching and learning experience for the child with dyslexia in special and mainstream settings in Ireland

This study examines and evaluates special provision for pupils with dyslexia in three different settings: reading schools, reading units and mainstream support. The research focused on the teaching and learning context for pupils with dyslexia, the support teacher, the mainstream teacher and the experience of the student. The main participants were teachers and tutors supporting pupils with dyslexia, and the parents of these children. Survey methods included questionnaires, focus group discussions, interviews and quantitative data on pupils' reading attainment. In addition, a total of six schools, two representing each model of support, were selected as case studies. This article reports part of a larger survey, which evaluated the effectiveness of three models of special provision for children with dyslexia in primary school. The study shows that there are academic and social benefits for the child with dyslexia who is enrolled in a special setting. However, placement in a reading school or reading unit per se does not guarantee that a child will ‘catch up’ with his or her peers. The findings reported a similarity in the methods and practices teachers use in both mainstream and special settings. The discussion suggests that if teachers are to ‘catch them before they fall’ there are serious questions that must be asked about how we are teaching basic literacy skills. The findings suggest an urgent need for a more balanced approach to teaching reading and writing.

Assessment of energy expenditure in children using the RT3 accelerometer

Abstract

The aim of this study was to evaluate the utility of the RT3 accelerometer in young children, compare its accuracy with heart rate monitoring, and develop an equation to predict energy expenditure from RT3 output. Forty-two volunteers (mean age 12.2 years, s = 1.1) exercised at two horizontal and graded walking speeds (4 and 6 km · h^?1, 0% grade and 6% grade), and one horizontal running speed (8 km · h^?1, 0% grade), on a treadmill. Energy expenditure and oxygen consumption ([Vdot]O₂) served as the criterion measures. Comparison of RT3 estimates (counts and energy expenditure) demonstrated significant differences at 4, 6, and 8 km · h^?1 on level ground (P < 0.01), while no significant differences were noted between horizontal and graded walking at 4 and 6 km · h^?1. Correlation and regression analyses indicated no advantage of vector magnitude over the vertical plane (X) alone. A strong relationship between RT3 estimates and indirect calorimetry across all speeds was obtained (r = 0.633–0.850, P < 0.01). A child-specific prediction equation (adjusted R ² = 0.753) was derived and cross-validated that offered a valid energy expenditure estimate for walking/running activities. Despite recognized limitations, the RT3 may be a useful tool for the assessment of children's physical activity during walking and running.

素质教育与高等学校德育课程改革与发展

素质教育并不是一个专门的教育学术语,但在我国却具有良好的纠正应试教育偏差的纠偏功能, 它要求高校德育课程按照教育本身的特点和功能进行设计与开发。长期以来,我国高校德育课程由于受传统学科课程观念的影响,形成了较为狭义的学科德育课程观念,即把德育课程仅仅理解为直接学科德育课程,较为重视直接学科德育课程建设,而忽视其他渠道德育课程建设,存在着德育课程主渠道与其他渠道之间的矛盾、德育课程稳定性与变化性的矛盾、德育课程结构和层次不清等问题。高校德育课程建设的基本思路是根据素质教育和教育改革和发展要求,树立一种大的德育课程观念,从直接学科德育课程、间接学科德育课程、活动德育课程、学校教育物质条件层面的隐性课程、组织制度层面的隐性课程、精神文化层面的隐性课程等多角度、全方位地进行德育课程综合性建设,更好地促进高校德育课程改革与发展。     

Assessment of energy expenditure in children using the RT3 accelerometer

The aim of this study was to evaluate the utility of the RT3 accelerometer in young children, compare its accuracy with heart rate monitoring, and develop an equation to predict energy expenditure from RT3 output. Forty-two volunteers (mean age 12.2 years, s = 1.1) exercised at two horizontal and graded walking speeds (4 and 6 km.h(-1), 0% grade and 6% grade), and one horizontal running speed (8 km.h(-1), 0% grade), on a treadmill. Energy expenditure and oxygen consumption (VO2) served as the criterion measures. Comparison of RT3 estimates (counts and energy expenditure) demonstrated significant differences at 4, 6, and 8 km.h(-1) on level ground (P < 0.01), while no significant differences were noted between horizontal and graded walking at 4 and 6 km.h(-1). Correlation and regression analyses indicated no advantage of vector magnitude over the vertical plane (X) alone. A strong relationship between RT3 estimates and indirect calorimetry across all speeds was obtained (r = 0.633-0.850, P < 0.01). A child-specific prediction equation (adjusted R2 = 0.753) was derived and cross-validated that offered a valid energy expenditure estimate for walking/running activities. Despite recognized limitations, the RT3 may be a useful tool for the assessment of children's physical activity during walking and running.     

An adaptive controller for nonlinear teleoperators with variable time-delays

In most real-life bilateral teleoperators the available physical parameters are uncertain and the communications exhibit variable time-delays. In order to confront these situations and only assuming that a bound of the time-delays is known, the present work reports an adaptive controller which ensures asymptotic convergence of both position errors and velocities to zero, provided that a sufficient condition on the control gains is met. Compared to previous related works that only treated constant time-delays, the stability analysis does not rely on the cascade interconnection structure of the local and remote nonlinear dynamics and the linear interconnection map. Instead, the paper employs a different Lyapunov candidate function that incorporates a strictly positive term, the local and remote position error. Some simulations, in free space and interacting with a rigid wall, and experiments, using two nonlinear manipulators, illustrate the performance of the proposed control scheme in the presence of uncertain parameters and variable time-delays.
