Reconceptualised family resemblance approach to nature of science in pre-service science teacher education

A recent framework on nature of science (NOS) is the Family Resemblance Approach (FRA). FRA presents NOS as a cognitive-epistemic and social-institutional system with a set of categories: aims and values, scientific methods, scientific practices, scientific knowledge and social-institutional aspects of science. Although FRA has been problematised philosophically and its implications for science education have been considered by science educators, its empirical adaptations in science education are limited. In order to illustrate the educational adaptations of FRA, we refer to Reconceptualised Family Resemblance Approach to Nature of Science or RFN. We present a study based on a funded pre-service science teacher education project whose aim was to design, implement and evaluate the impact of RFN strategies. Fifteen pre-service teachers participated in a 14-week teacher education intervention that infused RFN. A 70-item questionnaire was designed to investigate the outcomes of the teacher education intervention. Individual interviews with pre-service teachers were also conducted. Quantitative and qualitative data analysis suggest that the teacher education intervention had an overall significant impact on pre-service teachers’ views of NOS. The paper contributes to the understanding of how NOS can be incorporated in science teacher education using a new orientation to NOS based on FRA.     

Drawing Nature of Science in Pre-service Science Teacher Education: Epistemic Insight Through Visual Representations

Developing pre-service science teachers’ epistemic insight remains a challenge, despite decades of research in related bodies of work such as the nature of science (NOS) in science education. While there may be numerous aspects to this problem, one critical element is that the NOS is a meta-concept that demands higher-order cognitive skills. One possible strategy to facilitate pre-service teachers’ understanding of epistemic aspects of science is visualisation. Visual representations of objects and processes can be tools for developing and monitoring understanding. Although the NOS and visualisation literatures have been studied extensively, the intersection of these bodies of literatures has been minimal. Incorporating visual tools on the NOS in teacher education is likely to facilitate teachers’ learning, eventually impacting their students’ learning of the NOS. The objective of this paper is to illustrate how the visual tools of scientific knowledge and practices aspects of the NOS can be integrated in science teacher education in order to develop pre-service teachers’ epistemic insight. The paper presents an empirical study that incorporated visual tools about the NOS in primary science teacher education. Data on 14 pre-service teachers’ are presented along with in-depth case studies of 3 pre-service teachers illustrating the influence of the teacher education intervention. The qualitative analysis of visual representations before and after the intervention as well as verbal data suggests that there was improvement in pre-service teachers’ perceptions of the NOS. Implications for future research on visualisation of the NOS are discussed.     

Do reading practices make a difference? Evidence from PIRLS data for Hong Kong and Taiwan primary school Grade 4 students

This study examined the influence of classroom pedagogic reading practices and out-of-school practices in explaining why the reading attainment of Hong Kong Grade 4 students was superior to that of their counterparts in Taiwan in the 2006 Progress in International Reading Literacy Study. Analyses of scores from 9301 students (4712 from Hong Kong and 4589 from Taiwan) revealed that independent reading in school made a distinctive contribution to the reading performance of Hong Kong and Taiwan students after controlling for the effects of students’ and parents’ reading attitudes, the availability of supportive home educational resources and student engagement in a range of reading practices. Out-of-school informational reading was found to be negatively associated with students’ reading attainment for both Hong Kong and Taiwan students. There was evidence that reading aloud in class in Taiwan classrooms significantly contributed to the Taiwan students’ poor reading performance.     

Curriculum reform with a school-based approach: intellectual,structural and cultural challenges

Curriculum reform with a school-based approach is often assumed to offer schools and teachers autonomy at the site level, thus enabling them to develop a school-based curriculum and pedagogies to better fit the needs of students. Over the past decade, school-based curriculum development in Hong Kong has encountered issues that deserve worldwide attention and discussion. By reviewing the experiences of two schools in Hong Kong and drawing on international evidence, this study identifies key challenges and difficulties in school-based curriculum reform in three areas. Intellectually, there is a lack of a strong and broad shared knowledge base for curriculum development. As a result, most school-based curriculum initiatives have been piecemeal, fragmented and shallow. Structurally, many teachers have wasted time ‘re-inventing the wheel’ when developing school-based curricula. This effort has left them without sufficient time and energy to be effective in teaching. Culturally, reliance on school management to steer school-based reforms has prevented the development of a new culture in which teachers have the autonomy to make changes in their daily practices. Without cultural changes, curriculum reforms are not sustainable or effective. This study proposes a cooperative platform that integrates the strengths of central intelligence and school-based initiatives to maximise support for curriculum development at the teacher, school-site and system levels.     

Exploring the eye‐movement patterns as Chinese children read texts: a developmental perspective

This study was to investigate Chinese children's eye patterns while reading different text genres from a developmental perspective. Eye movements were recorded while children in the second through sixth grades read two expository texts and two narrative texts. Across passages, overall word frequency was not significantly different between the two genres. Results showed that all children had longer fixation durations for low‐frequency words. They also had longer fixation durations on content words. These results indicate that children adopted a word‐based processing strategy like skilled readers do. However, only older children's rereading times were affected by genre. Overall, eye‐movement patterns of older children reported in this study are in accordance with those of skilled Chinese readers, but younger children are more likely to be responsive to word characteristics than text level when reading a Chinese text.     

Children exposed to child maltreatment and intimate partner violence: a study of co-occurrence among Hong Kong Chinese families

Objective

This study assessed the co-occurrence of child maltreatment and intimate partner violence (IPV) and examined the association between them.

Method

The cross-sectional study recruited a population-based sample of 1,094 children aged 12-17 years in Hong Kong. Structured questionnaires were used to collect data from the children. The prevalence of occurrence of child abuse and neglect by parents and exposure to IPV in both the past year and lifetime was examined, and their correlates were assessed using univariate and multivariate logistic regression.

Results

The results show that 26% and 14.6% of child participants had been exposed to IPV physical assault, and 44.4% and 22.6% had been subjected to a parent's corporal punishment or to physical maltreatment from a parent in their lifetime and the year preceding the study, respectively. Among those families characterized by IPV, 54.4% and 46.5% were involved in child physical maltreatment over the child's lifetime and in the preceding year, respectively.

Conclusions

Multivariate logistic regression analyses revealed that children exposed to IPV were at higher risk of being victims of neglect, corporal punishment, and physical maltreatment or severe physical maltreatment by their parents than children who were not exposed to IPV, even when child and parent demographic factors were controlled for.

Practical implications

The higher risk of child physical maltreatment associated with IPV highlights the need for an integrated assessment to screen for the presence of multiple forms of family violence within the family, and for intervention to assess effective responses to both IPV and child maltreatment by child protective service workers and domestic violence agencies.     

Dimensions of Market Demand Associated with Taekwondo Schools in North America: Development of a Scale

Since the introduction of martial arts in the United States, the sport of Taekwondo (TKD) has rapidly grown and developed. Although the elevated interest in this sport has increased the magnitude of the TKD market, no systematic studies have been conducted to investigate the market demand variables associated with TKD schools in North America. To a great extent, lack of study has been due to the unavailability of a viable measure. The purpose of this study was to identify the dimensions of market demand for TKD schools and develop the Scale of Market Demand Associated with Taekwondo School (SMD-TKD). Research participants (N = 205) were TKD school members who were 18 years and older from 22 TKD schools in major cities of Florida. A factor analysis using principal component extraction and varimax rotation produced six factors with 51 items returned (i.e., Personal Benefits, School Operation, Instruction Quality, Program Offering, Locker Room, and Cultural Learning). Multiples regression analysis revealed that all market demand factors, except for Program Offering and Cultural Learning, were positively (p < .05) predictive of TKD consumption, suggesting that the SMD-TKD is useful for marketing studies on TKD consumers.

An incidence survey of battered children in two elementary schools of Seoul

Among the 1,142 girls and boys aged 9 to 11 years, 8.2% were seriously battered, 58% were mildly battered and 33.8% were unbattered during the past year. Child battering was more serious in families in the lower social strata, with poor living conditions, in broken families such as those with stepparents or absent mothers, and where parents were unskilled workers or unemployed. Finally, child battering was closely related to all other forms of family violence.
