Learning Multi‐unit Number Concepts and Understanding Decimal Place Value

Research indicates that many errors in secondary school mathematics can be attributed to lack of understanding of decimal place value. Recently it has been suggested that this arises from an underlying weakness in integer place value concepts and perception of multidigit numbers in unitary terms rather than base ten, multi‐unit structures. Development of place value and multidigit number concepts was examined in individual interviews with 262 primary school pupils, aged between 7 and 12 years, using subjects’ concrete representations of written numerals and associated verbal explanations. Almost all the children had some understanding of integer place value; most older children had multi‐unit concepts of three‐ or four‐digit numbers; but two‐digit numbers, especially values of 20 or less, were frequently perceived in terms of units by all age groups. This was particularly common for the value ten where 55% of subjects displayed unitary concepts. Implications for understanding and teaching decimal place value are discussed.     

Teaching with animals: Goals and guidelines

Conclusion In summary, teaching with animals does not require keeping animals confined. No longer need teachers feel obligated to accept the gerbils and hamsters parents don’t want at home. No longer must they feel guilty when the third rabbit and the dozenth baby turtle dies in the classroom. By adopting respect for life as their goal, and the Golden Rule as their guide in teaching with animals, child caregivers can be liberated from their old role as animal caretakers. Teachers, children-and, certainly, the animals—all benefit from the change.     

Sport for All? Insight into stratification and compensation mechanisms of sporting activity in the 27 European Union member states

Physical activity is an important public health issue and the benefits of an active lifestyle in relation to well-being and health have been strongly emphasised in recent years in Europe, as well as in most parts of the world. However, previous research has shown that physical activity within Europe and its member states is stratified. The present article gains insight into: (1) the geographical stratification; and (2) the social stratification of physical activity in the 27 European Union member states in 2005. Special attention is given to sporting activity in comparison to other forms of physical activity (transport, occupation and household). By doing this we intend to develop a picture of physical activity, in particular sporting activity, within the European Union. In addition, we want to verify whether low sporting activity levels are counterbalanced by other pieces of the total ‘menu of physical activities’. Based on Eurobarometer data from 2005 (N=26,688), bivariate analyses show that 4 out of 10 Europeans are not exposed to sporting activity. Moreover, particular subgroups of non-sportive citizens could be distinguished: South and East Europeans, and women, the elderly, individuals with a lower educational level and rural citizens. Our hypothesis that these groups would compensate for their non-sporting activity by being physically active in other domains could only be confirmed for women and rural citizens, in particular with regard to household physical activity. To understand the underlying structure of these possible compensation mechanisms, additional quantitative and qualitative research is needed. Nevertheless, because of societal trends towards an inactive society, the role of sporting activity will be increasingly important in the future for all inactive subgroups. For this purpose, not only should necessary resources and key stakeholders be identified, but also more importantly the social and environmental barriers for sporting activity need to be addressed.     

Purposeful pauses: teacher talk during early childhood mathematics activities

This paper describes how early childhood teachers' incorporation of pauses raises the quality of talk-in-interaction during play-based mathematics activities. Responses of both children and teachers are shown to be more contingent and expansive when conversations include protracted pauses than during interactions in which pauses are largely absent. Pauses provided children with opportunities to initiate topics and facilitated more equitable access to discourse moves for children. By pausing before responding to a child's conversational gambit, teachers gained opportunities to assess children's demonstrated numeracy-related skills and understanding, and could thus provide authentic, individualised scaffolding. Pauses were not necessarily silent: a pause in an interaction with one child could be used strategically to model the learning interaction with a second child before returning to the first child in order to continue the discourse sequence.     

Integrating technology in a field-based teacher training program: The PT3@ASU project

The Preparing Tomorrow’s Teachers to Use Technology (PT3) initiative has funded various efforts to improve and enhance the technology preparation of preservice teachers. At Arizona State University, these efforts have focused on providing preservice teachers with opportunities to develop, implement, and evaluate their own instructional activities that utilize technology effectively and appropriately in authentic situations, to give them the myriad of tools necessary to integrate technology into teaching and learning activities. This paper focuses on the integration of these efforts into the field-based elementary education program, and discusses our formative evaluation of the field-based technology integration model, through the following questions: What are the preliminary successes of the model with regard to student perceptions, attitudes, and integration of technology into instructional activities? and What components of the model require additions or modifications?     

Encouraging transformation and action competence: A Theory of Change evaluation of a sustainability leadership program for high school students

Abstract

Make a Difference (MAD) is a sustainability leadership program for high school students in Auckland, New Zealand. It offers a residential camp and follow-up activities. This article documents a participatory, utilization-focused evaluation of MAD, based on a Theory of Change approach. We ran workshops with MAD coordinators and students and conducted a survey with previous participants. This identified the core developmental and action outcomes of MAD, and the role of transformation and action competence in inspiring change. We discuss the benefits and limitations of both MAD and our evaluation approach and offer recommendations for others working on youth sustainability programs.     

Developing an HIV/AIDS Education Curriculum for Takalani Sesame, South Africa's Sesame Street

The HIV/AIDS pandemic in South Africa has prompted a need for extensive efforts to educate citizens of all ages about the disease and ways of coping with its impact. This paper describes the process of developing an HIV/AIDS education curriculum for Takalani Sesame, an educational media project for young South African children. The process began with formative research with adults and children, and extensive discussions with HIV/AIDS health specialists. Guided by the research and advice from specialists, a team of educators developed a comprehensive curriculum that the Takalani Sesame production team will use to create HIV/AIDS education messages for television, radio and outreach materials for children ages 3-7 and the adults who care for them.
