Challenges and Changes: Developing Teachers’ and Initial Teacher Education Students’ Understandings of the Nature of Science

Teachers need an understanding of the nature of science (NOS) to enable them to incorporate NOS into their teaching of science. The current study examines the usefulness of a strategy for challenging or changing teachers’ understandings of NOS. The teachers who participated in this study were 10 initial teacher education chemistry students and six experienced teachers from secondary and primary schools who were introduced to an explicit and reflective activity, a dramatic reading about a historical scientific development. Concept maps were used before and after the activity to assess teachers’ knowledge of NOS. The participants also took part in a focus group interview to establish whether they perceived the activity as useful in developing their own understanding of NOS. Initial analysis led us to ask another group, comprising seven initial teacher education chemistry students, to take part in a modified study. These participants not only completed the same tasks as the previous participants but also completed a written reflection commenting on whether the activity and focus group discussion enhanced their understanding of NOS. Both Lederman et al.’s (Journal of Research in Science Teaching, 39(6), 497–521, 2002) concepts of NOS and notions of “naive” and “informed” understandings of NOS and Hay’s (Studies in Higher Education, 32(1), 39–57, 2007) notions of “surface” and “deep” learning were used as frameworks to examine the participants’ specific understandings of NOS and the depth of their learning. The ways in which participants’ understandings of NOS were broadened or changed by taking part in the dramatic reading are presented. The impact of the data-gathering tools on the participants’ professional learning is also discussed.

Studying Social Development and Learning Disabilities is Not for the Faint‐Hearted: Comments on the Risk/Resilience Framework

Studying social dimensions of learning disabilities is not for the faint‐hearted, in light of the multiple and interactive characteristics of these students and their social/cultural environments. Given the allure of the risk/resilience lens to make sense of these complexities, it would be easy to embrace these concepts too hastily. Four questions seem particularly important: What do we mean by risk and resilience factors? How do we characterize learning disabilities as risk factors?“At risk” for what? How should this framework guide intervention efforts? Rigorous thinking about these issues may enhance the promise of risk/resilience models for future research on social development.     

The changing work of teacher educators in Aotearoa New Zealand: a view through activity theory

The study of recruitment practices for teacher educators (TEs) in Aotearoa New Zealand (NZ) universities reveals the academic category of TE constituted along three related trajectories: a professional expert (not required to research), a traditional academic (not required to hold a teaching qualification or teacher’s practicing certificate), and one who is dually qualified, to teach (as a registered NZ teacher) and to research. It is the dually qualified type of TE who can service the full scope of university-based initial teacher education (UBITE). Recent recruitment practices have, however, focused on employment of professional experts and traditional academics. Drawing from document analyses and interviews, we present a picture of changing work for TEs. Our study argues that policy environments and universities’ responses are changing the objects, rules, and divisions of labour in UBITE. We comment on the evolution of initial teacher education in NZ, its likely trajectory, and its potential for development.

日光拨开黑夜的长发,夜影裹起白昼的身躯。光与影欢乐又悲伤,无自觉地浮起、飘落,都是纷纷的美丽。黑夜敛起了忧郁的目光,白昼舞落了欢愉的长袖。光与影不相为伴,所见的,都是炫目的纯净。     

Genetic and Environmental Influences on Perceptions of Self-Worth and Competence in Adolescence: A Study of Twins, Full Siblings, and Step-Siblings

Although it is generally assumed that the origins of adolescents' perceptions of self-competence lie in shared family environmental influences, the contributions of nonshared environmental or genetic influences have not been explored. We investigated sibling resemblance for perceived competence and self-worth in 720 adolescent pairs aged 10 to 18 years, using a twin, full sibling, and step-sibling design. Our goals were to assess the magnitude of shared and nonshared environmental influences and to disentangle resemblance due to shared genetic heritage from that due to shared environmental experiences. Shared environment was not significant for any of the scales. 4 of the subscales showed significant genetic influence: scholastic, social, physical, and athletic competence. We also explored possible sources of genetic influences on perceived competence. Bivariate models revealed common genetic variance between scholastic competence and vocabulary and social competence and sociability. These measures, however, did not account for all of the genetic variance in perceived social and scholastic competence.     

Leadership,partnerships, and organizational development: exploring components of effectiveness in three full-service community schools

Full-service community schools are viewed as an approach to improve educational opportunities and outcomes for underserved student populations. The realization of these goals, however, is not guaranteed. According to Richardson’s (2009) research-based model of highly effective community schools (HECS), the effectiveness of full-service community schools depends on 3 interrelated components: leadership, partnerships, and organizational development. This qualitative case study uses the HECS model to examine different levels of effectiveness among 3 full-service community schools in an urban district in the eastern United States. The article concludes with a discussion of the implications of Richardson’s model for practice and research.     

Induction and Efficacy: A Case Study of New Zealand Newly Qualified Secondary Science Teachers

This paper reports on 20 newly qualified secondary science teachers (NQSSTs) participating in a New Zealand study on teachers?? early professional learning. The focus of our study is how these new teachers were nurtured to become competent science teachers, confident of their ability to positively influence student learning. Based on responses to a graduating questionnaire and three interviews across their first 18?months of teaching, we look at the effect of induction and contextual factors on the teachers?? efficacy. While the NQSSTs overall reported relatively constant ratings of self-efficacy, they demonstrated different patterns of declared efficacy across this 18-month period. Findings regarding the influence of induction practices and contextual factors on the efficacy of these teachers are mixed.
