Effect of frequency response on language learning

Conclusion The number of errors in the recognition of unfamiliar phonemic contrasts increases with high or low frequency limitation. This increase in errors is not the same for all phonemic contrasts, but the contrasts are affected in the same manner by either limitation. Consonants are affected more, and German shows a much clearer picture than does French. Rank ordering contrasts according to numbers of errors give support to a concept of“order of difficulty” of recognition of foreign phonemic contrasts.     

Influences on children’s environmental cognition: a comparative analysis of New Zealand and Mexico

This paper investigates Mexican and New Zealand children’s conception of the environment and their understandings of environmental issues, focusing on how personal experiences, culture and school-based environmental education (EE) programmes influence their perspectives. Sixty Year 5 children (age 9–11) from three schools in Dunedin (New Zealand) and three schools from Ensenada (Mexico), their teachers and school principals were interviewed. The study found that children from both cities had limited opportunities for contact with nature. Most children understood the environment as nature, and did not typically link environmental problems to human activities or social causes. Rarely were children critical of the effect of socio-economic structure on the environment. The analysis shows that children’s understandings of the environment are connected to their personal experiences and mediated by culture. Children from Ensenada had a more global perspective on environmental issues but a more passive attitude towards their local environment, participating in fewer environmental activities than children from Dunedin. In both countries, children from schools with an EE programme did translate environmental practices learnt at school into environmental practices at home. Based on our results, EE could be improved by considering the cultural context, enhancing children’s contact with nature, encouraging critical thinking and more environmental activities.     

Learn something new in 20 minutes: Bite Size sessions to support research and teaching

The School of Health and Related Research (ScHARR) at The University of Sheffield run an innovative series of informal 20‐minute Bite Size sessions to help staff and students teach, research, collaborate and communicate more effectively. The sessions have two clear strands: one focused on teaching and the other on research. The remit is not to teach people how to use something in their work or study, but to let them know why they should use it and how they can employ it. By introducing participants to the possibilities and how they can apply ideas and technologies in their work and study in an enthusiastic manner, it is possible to send them away with at least the intention to explore and experiment. The evidence shows that this organic approach is working – staff and students are starting to use many of the tools that Bite Size has covered. Any kind of widespread change within organisations can be hard to deliver, but by bringing champions on your side and delivering sessions in a convenient, informal and timely manner; good practice and ideas can spread naturally.

The influence of experience on student teachers' beliefs about inclusion

Abstract

Teacher beliefs influence the implementation of inclusion practices in the classroom. Therefore, the importance of developing positive beliefs during the preservice years cannot be overstated. The purpose of this study was to examine the influence of professional experiences on students’ beliefs about inclusion. This qualitative study was comprised of a series of interviews (group and individual) and analysis of reflective writings for six student teachers. Findings indicated that experiences both professional and personal contribute to the development of the students’ beliefs about inclusion. If these experiences were positive, the preservice teachers were more positively disposed to the concept of inclusion. Therefore, teacher training programs are afforded the opportunity to influence preservice teachers’ development of positive beliefs about inclusion which may ultimately affect the inclusion process.     

Forthcoming events

The aims of this study were to quantify the effects of factors such as mode of exercise, body composition and training on the relationship between heart rate and physical activity energy expenditure (measured in kJ?·?min^?1) and to develop prediction equations for energy expenditure from heart rate. Regularly exercising individuals (n = 115; age 18?–?45 years, body mass 47?–?120?kg) underwent a test for maximal oxygen uptake ([Vdot]O_2max test), using incremental protocols on either a cycle ergometer or treadmill; [Vdot]O_2max ranged from 27 to 81?ml?·?kg^?1?·?min^?1. The participants then completed three steady-state exercise stages on either the treadmill (10?min) or the cycle ergometer (15?min) at 35%, 62% and 80% of [Vdot]O_2max, corresponding to 57%, 77% and 90% of maximal heart rate. Heart rate and respiratory exchange ratio data were collected during each stage. A mixed-model analysis identified gender, heart rate, weight, [Vdot]_2max and age as factors that best predicted the relationship between heart rate and energy expenditure. The model (with the highest likelihood ratio) was used to estimate energy expenditure. The correlation coefficient (r) between the measured and estimated energy expenditure was 0.913. The model therefore accounted for 83.3% (R ²) of the variance in energy expenditure in this sample. Because a measure of fitness, such as [Vdot]O_2max, is not always available, a model without [Vdot]O_2max included was also fitted. The correlation coefficient between the measured energy expenditure and estimates from the mixed model without [Vdot]O_2max was 0.857. It follows that the model without a fitness measure accounted for 73.4% of the variance in energy expenditure in this sample. Based on these results, we conclude that it is possible to estimate physical activity energy expenditure from heart rate in a group of individuals with a great deal of accuracy, after adjusting for age, gender, body mass and fitness.     

Service Learning in Preschool: An Intergenerational Project Involving Five–Year-Olds, Fifth Graders, and Senior Citizens

Service Learning is a powerful form of experiential pedagogy that is gaining popularity in classrooms from preprimary settings through graduate school. It involves students in activities that explicitly and intentionally integrate community involvement with appropriate academic objectives. This article describes an intergenerational service learning project that brought together preschoolers, golden-agers, and at-risk elementary-aged students. Lunch Time Book Buddies—Pass It On included both direct service and indirect service and made valuable contributions to young children's developing literacy, social-emotional, physical, and cognitive abilities.     

“If only my eyes were different”: The loss of identity and the under-utilization of black children’s educational potential — rethinking social justice and assimilation

This study explores how social identity is formed in the United States of America. In particular, it examines the social, economic and educational problems experienced by underachieving Black American children and issues of social inequality along with their implications for social justice. Against the background of matters of group identity and its maintenance or loss, the author reflects on the under-utilization of Black American children’s educational and human potential. She also suggests a rationale for re-conceiving the goal of social justice and how it is to be achieved, as well as the paradigm of cultural assimilation.     

The Role of Family Childcare Providers in Early Intervention

In family childcare, the program of services is situated within in the providers' own homes. The purpose of this inquiry is to review the literature from special education in light of current practices in family childcare. In addition, key characteristics unique to the provider's care giving program will be examined in relation to the needs of children with disabilities and their families. Finally, recommendations for establishing coordinated efforts among professional support systems and providers on behalf of such children will be defended.
