Postural Influences on the Development of Infant Lateralized and Symmetric Hand‐Use

Within‐individual variability is such an apparent characteristic of infant handedness that handedness is believed to consolidate only in childhood. Research showed that manifest handedness is influenced by emerging postural skills (sitting, crawling, and walking). In this investigation, it was proposed that symmetric hand‐use (tendency to acquire objects bimanually), rather than lateralized hand‐use (the use of one hand more than the other), may be influenced by postural changes. Trajectories of lateralized and symmetric hand‐use for object acquisition were examined in 275 infants tested monthly from 6 to 14 months. Multilevel modeling revealed that change in lateralized hand‐use is unrelated to developmental transitions in infant posture, whereas the trajectory of symmetric hand‐use changes significantly with the development of postural skills.     

Students reflecting on test performance and feedback: an on-line approach

Undergraduate students accessing on-line tests in Human Biology in three Western Australian universities were asked to complete an on-line post-test reflective survey about their perceptions of their test performance in light of automated feedback. The survey allowed pre-determined choices and comment text boxes relating to students’ perceptions of their performance, self-identified areas of difficulty and suggested strategies for improving test performance. One-third of students undertaking on-line tests responded to the optional survey, and 60% of respondents thought reflecting on feedback was useful. Students reflecting on formative rather than summative assessment reported a more strategic approach to testing, often using it to assess their knowledge and prepare for future assessment. Their reflections were more internally focused on motivation and preparation compared with those assessed summatively. Respondents were more likely to be female, older, more experienced learners who had scored well in the test. Younger respondents expected higher scores than they achieved and were less likely to reflect, but, when they did, were more likely to select pre-determined reasons for their performance and less likely to suggest strategies for improvement. These results support formal training and scaffolded integration of reflection into on-line assessment feedback, especially for less experienced learners.     

Instructing First-Grade Children on Patterning Improves Reading and Mathematics

Research Findings: In each of 16 public school classrooms serving multiethnic low-income neighborhoods, 2 first graders were assigned to be taught patterning, 2 to be taught reading, 2 to be taught mathematics, and 2 to be taught social studies for 15-min sessions 3 days per week for 6 months. Assignment within each classroom was randomized. The children's mean age was 6 years, 5.19 months. Patterning instruction included instruction on symmetrical patterns, patterns with increasing numbers of elements, and patterns involving the rotation of an object through 6 or 8 positions. In May, the 120 children still available were tested on patterns, reading, and mathematics. Patterning instruction had large, fully mediated effects on both reading and mathematics. There were no significant differences on some individual scales, but on others children who received patterning instruction scored best, often by grade equivalents of 4 to 8 months. Extant explanations of the efficacy of patterning instruction are reviewed, and the potential importance and limitations of its role in early education are discussed. Practice or Policy: Patterning instruction should be extended to more complex patterns than the alternations currently used in elementary schools in order to produce important improvements in both reading and mathematics.     

Science Teachers Without Classrooms of Their Own: A Study of the Phenomenon of Floating

“Floating” teachers, or teachers without their own classroom, experience unique affordances and constraints as they develop professionally. To increase the knowledge in this area, this study looks at how traveling to different classrooms affects beginning secondary science teachers’ development and instruction. The participants in this study were three first-year floating secondary science teachers whose experiences were analyzed through a cultural historical activity theory framework. The data revealed how floating can either support or constrain the development of beginning science teachers, and limit the implementation of standards-based instruction. Finally, this study shows that high levels of human, physical, and social resources are necessary for progress towards standards-based science teaching. It suggests that if science teachers must move to different classrooms, we need to create ways in which to support their instruction and development. Furthermore, this study recommends that all teachers and supervisors work toward a deeper understanding of the school community’s role in the experience of the floating science teacher.     

Translating Current Science into Materials for High School via a Scientist–Teacher Partnership

Scientist-teacher partnerships are a unique form of professional development that can assist teachers in translating current science into classroom instruction by involving them in meaningful collaborations with university researchers. However, few reported models aim to directly alter science teachers’ practices by supporting them in the development of curriculum materials. This article reports on a multiple case study of seven high school science teachers who attended an ongoing scientist–teacher partnership professional development program at a major Southeastern research university. Our interest was to understand the capacity of this professional development program for supporting teachers in the transfer of personal learning experiences with advanced science content and skills into curriculum materials for high school students. Findings indicate that, regardless of their ultimate success constructing curriculum materials, all cases considered the research grounded professional development supports beneficial to their professional growth with the exception of collective participation. Additionally, the cases also described how supports such as professional recognition and transferability served as affordances to the process of constructing these materials. However, teachers identified multiple constraints, including personal learning barriers, their classroom context, and the cost associated with implementing some of their curriculum ideas. Results have direct implications for future research and the purposeful design of professional development experiences through scientist-teacher partnerships.     

The impact of professional development on early childhood educators’ confidence,understanding and knowledge of education for sustainability

In recent times, Australia has recognised and enacted a range of initiatives at service, system and community levels that seek to embed sustainability into the early childhood sector. This paper explores the impact of a professional development (PD) session that provided opportunities for early childhood educators to learn and share ideas about the theory and practice of sustainability generally and early childhood education for sustainability (ECEfS) specifically. The PD was entitled ‘Living and Learning about Sustainability in the Early Years’ and was offered on three occasions across Tasmania. A total of 99 participants attended the three PD sessions (one 5 hour; two 2 hour). The participants had varying levels of experience and included early childhood teachers, centre based educators and preservice teachers. At the start and end of the PD, participants were invited to complete a questionnaire that contained a series of likert scale questions that explored their content knowledge, level of understanding and confidence in regards to ECEfS. Participants were also asked at the start and end of the PD to ‘list five words you think of when you consider the word sustainability.’ A model of teacher professional growth was used to conceptualise the results related to the changes in knowledge, understanding and confidence (personal domain) as a result of the PD related to ECEfS (external domain). The likert-scale questions on the questionnaire revealed significant positive changes in levels of knowledge, understanding and confidence from the start to the end of the PD. Differences as a function of length of PD, level of experience and role are presented and discussed. The ‘5 words’ question showed that participants widened their understandings of ECEfS from a narrow environmental focus to a broader understanding of the social, political and economic dimensions. The early childhood education and care (ECEC) sector has been characterised as having a pedagogical advantage for EfS suggesting that early childhood educators are well placed to engage with EfS more readily than might educators in other education sectors. This article argues that PD is necessary to develop capability in educators in order to meet the imperatives around sustainability outlined in educational policy and curriculum documents in ECEC.     

Exploring three White American teachers’ dispositional stances towards learning about racial,cultural, and linguistic diversity

This study, situated in the United States, is set in a context where large and growing numbers of children from non-dominant backgrounds populate American public schools while the vast majority of teachers teaching in US schools are White, monolingual women who may not have the requisite expertise to teach children from non-dominant backgrounds. This work focuses on the learning of three White teachers enrolled in a literacy course designed to foster teachers’ understandings of racial, linguistic, and cultural diversity. Results revealed that the three focus teachers, all members of a small online Book Club within the focus course, assumed different dispositional stances towards learning about diversity. Moreover, their overall dispositional stances shaped the ways they positioned themselves as learners in the course as well as what they learned in the course.     

Using Social Media to Assess Conceptualizations of Sexuality

There is currently no validated model explaining the variability of sexual expression. This has created a scenario where sexuality, as a construct, is purely intuitive. Sexuality educators have frequently presented the Circles of Sexuality, a model that contends that sexuality is a combination of intimacy, sensuality, sexual health/behaviors, sexual identity, and sexualization. Adapting photovoice methodology and using the social media site Tumblr, the current analysis used this model to assess the social conceptualization of sexuality. Results indicate that the circles are unequally represented, with intimacy underrepresented and sexual identity overrepresented. Implications for sexuality educators, clinicians, and researchers are discussed.
