The Integration of Environmental Education into Two Elementary Preservice Science Methods Courses: A Content-Based and a Method-Based Approach

To examine the notion of environmental education (EE) as context for integrating the elementary curricula, we engaged in a multi-case study analysis (Yin 2009) of two preservice elementary science methods courses that utilized an experiential reflective approach—case one (University A) through a science content focus (i.e., sustainability) and case two (University B) through a method focus (i.e., problem-based learning). We examined preservice teachers’ understandings of EE, their ideas to incorporate EE into their future teaching, and their conceptions of EE as a context for integration. Results indicate that both foci (content and method) were successful in building EE content, helping preservice teachers to envision EE in their future classrooms, and promoting EE as a context for integrating their instruction. Based on these results, we offer recommendations for the incorporation of EE as a context for integration into the elementary science methods course.     

A Complex Case: Using the case study method to explore uncertainty and ambiguity in undergraduate business education

The case method is a definitive and foundational technology in business education. It was first developed as a vocational training tool equipping students for future employment. In this conception, the organisation was seen as a machine, and managers as the engineers who would maintain it through planned interventions. The case method allowed aspiring managers to practise intervention skills in a safe environment. Since the origins of the case method in US business schools before the First World War, conceptions of organisations have moved on. They are no longer seen as machine-like, but as complex, ambiguous, and protean. The 'wicked' problems that potential managers will face in an uncertain world require the development of critical thinking and sensemaking abilities. While the traditional approach to the case continues, its use as a vehicle to explore and manage complexity and ambiguity is emerging, although this is facing resistance from some students and staff.     

The Journey of Becoming a Mother

Nature intends that the physical and hormonal changes of pregnancy insure the growth and development not just of the baby but of the mother. The physical and emotional changes of pregnancy and, then, labor, birth, and breastfeeding play vital roles in guiding women on the journey of becoming a mother. Standard prenatal care and medicalized labor and birth interfere in powerful ways with nature''s plan and, consequently, women''s ability to negotiate this journey. In this column, these issues are explored, and implications for childbirth education are discussed.     

In This Issue—The Impact of Birth Physiology on the Transition to Motherhood

In this column, the associate editor of The Journal of Perinatal Education discusses the impact of birth physiology on the transition to motherhood. The associate editor also describes the contents of this issue, which offer a broad range of resources, research, and inspiration for childbirth educators in their efforts to promote, support, and protect natural, safe, and healthy birth.     

Preschool Children's Judgments about Hypothetical and Actual Transgressions

Preschoolers' ( N = 112) judgments about hypothetical and actual moral and conventional transgressions were examined. Equal numbers of boys and girls at 2 ages (3 and 4 years old) either made judgments about 8 hypothetical moral and conventional transgressions or were interviewed on the same dimensions about 8 naturally occurring moral and conventional transgressions they witnessed in their preschools. Children judged both hypothetical and actual moral transgressions to be more serious, punishable, generalizably wrong, and independent of rules and authority than conventional transgressions. Regardless of domain, hypothetical transgressions were judged to be more wrong independent of rules than actual transgressions, and hypothetical (but not actual) moral transgressions were judged to be more independent of rules than conventional transgressions. 3-year-old girls judged the wrongness of actual moral transgressions to be more independent of authority than did 3-year-old boys. Similar findings were obtained when hypothetical and actual transgressions were matched, and domain differences were still obtained when individual items were examined. Findings are discussed in terms of previous research on preschoolers' conceptions of rules and transgressions.     

Engaging student teachers in meaningful reflective practice

This paper examines the use of peer-videoing in the classroom as a tool to promote reflective practice among student teachers. Twenty pre-service teachers from a variety of subject disciplines participating in a Post-Graduate Diploma in Education programme in an Irish university participated in the study. The practice of encouraging student teachers working in the same school to participate in structured video analysis avoids the impact of external observers whose role is largely evaluative and endorses a collaborative model that promotes dialogue and shared learning. This practice promotes a culture of observation and critical dialogue in a profession which has traditionally been characterised by isolation, while at the same time fostering and validating the voice and experience of the student teacher. Locating the discussion within the framework of the theoretical literature on reflective practice, the purpose of this paper is to contribute to the international debate over best practice in supporting, encouraging and scaffolding reflective practice. It comments on the implications of reflective dialogue for the modernisation of teacher education and offers guidelines on how best to scaffold and promote reflectivity.     

A Longitudinal Study of Predictors of Spatial Ability in Adolescent Females

This study examined the longitudinal predictability of spatial ability in late-adolescent females by retesting 11-year-old girls studied by Newcombe and Bandura at age 16. Spatial ability at age 16 was predicted longitudinally from masculinity of the ideal self on a scale of intellectually relevant attributes at age 11, wanting to be a boy at age 11, and, negatively, by feminine expressivity at age 11. No timing of puberty or lateralization effects were observed. The findings strengthen evidence that sex-related differences in spatial ability could be experientially determined, and help to focus the search for exactly how this occurs. The findings also cast doubt on the idea that sex-related differences in spatial ability could be caused by sex differences in timing of puberty or lateralization, although other biological mechanisms remain plausible.     

秦始皇兵马俑博物馆室内含硫颗粒物的SEM-EDX研究

本文对秦始皇兵马俑博物馆室内采集的长短期降尘、大气悬浮颗粒物和彩绘漆层进行了SEM-EDX研究，在大气悬浮颗粒、短期和长期降尘中，含硫颗粒的粒径分别为0.9～22.8μm、1.0～29.0μm和1.2～37.7μm，多为石膏与粘土或石英以内部混合的状态存在。降尘中的附着型絮状硫酸钙多于大气悬浮颗粒物中，显示降尘和大气中的二氧化硫发生了累进的化学反应。彩绘漆层表面的坑和裂隙附近观察到原位生长的硫酸钙晶体，显示漆层材料或降尘颗粒物与大气二氧化硫之间的酸化学反应，可能是彩绘漆层表面受侵蚀形成微小坑和裂隙的原因之一。
