Student leadership in small group science inquiry

Background: Science educators have sought to structure collaborative inquiry learning through the assignment of static group roles. This structural approach to student grouping oversimplifies the complexities of peer collaboration and overlooks the highly dynamic nature of group activity.

Purpose: This study addresses this issue of oversimplification of group dynamics by examining the social leadership structures that emerge in small student groups during science inquiry.

Sample: Two small student groups investigating the burning of a candle under a jar participated in this study.

Design and method: We used a mixed-method research approach that combined computational discourse analysis (computational quantification of social aspects of small group discussions) with microethnography (qualitative, in-depth examination of group discussions).

Results: While in one group social leadership was decentralized (i.e., students shared control over topics and tasks), the second group was dominated by a male student (centralized social leadership). Further, decentralized social leadership was found to be paralleled by higher levels of student cognitive engagement.

Conclusions: It is argued that computational discourse analysis can provide science educators with a powerful means of developing pedagogical models of collaborative science learning that take into account the emergent nature of group structures and highly fluid nature of student collaboration.     

STEM Career Changers’ Transformation into Science Teachers

This study examines the transformation (professional growth) of career-changing women scientists who decided to become teachers. Drawing upon Mezirow’s Transformative Learning Theory, we tracked their transformation for 3 years. Our findings revealed multiple identities, disorientation, a perceived sense of meaninglessness, loss and eventual regain in confidence, gain in pedagogical knowledge and skill, and changed perceptions of the social roles of science teachers and scientists. Driven by personal choice or need (financial, intellectual), such transformations were achieved through active pursuit of meaning in one’s work, critical assessment of assumptions, planning, and trying on the unfamiliar role of a science teacher. It is argued that such transition entails complex changes in thinking about science teaching and identifying oneself as a science teacher.     

Improving performance aligning business analytics with process orientation

How to align business analytics with process orientation initiatives and how management can influence a synergistic accomplishment of these two elements in order to streamline organizational performance is a foremost managerial issue. By means of a quantitative research effort, a study was designed to investigate the relationships among these constructs. Empirical data were collected in 2011 from a survey of 368 large and mid-sized industrial and service companies headquartered in Brazil. A quantitative analysis was performed, and both the reliability and validity of the scales were evaluated prior to using structural equation modeling. The results demonstrate that the direct effects among BPO, analytical indicators and performance can be taken as statistically significant. The findings also demonstrate that BPO and analytical indicators can be taken as predictors of performance. The paper discusses these results and their managerial implications, as well as some research paths for future studies on the topic.     

Yo-Yo Intermittent Endurance Test-Level 1 to monitor changes in aerobic fitness in pre-pubertal boys

The present study aimed to examine the performance and heart rate responses during the Yo-Yo Intermittent Endurance Test-Level 1 (Yo-Yo IE1) in children under the age of 10. One hundred and seven male children (7–9 years) performed the Yo-Yo IE1 at the beginning (M₁), middle (M₂) and end (M₃) of the school year. Data from individual heart rate curves of the Yo-Yo IE1 were analysed in order to detect the inflection point between an initial phase of fast rise in heart rate values and a second phase in which the rise of the heart rate values is much smaller. The distance covered in the Yo-Yo IE1 improved from M₁ to M₃ (884 ± 496 vs. 1032 ± 596 m; p < 0.05; d = 0.27), with intermediate values for M₂ (962 ± 528 m). Peak heart rate (HR_peak) decreased from M₁ to M₂ and M₃ (204 ± 9, 202 ± 9 and 200 ± 9 bpm, respectively; p < 0.05; d = 0.25–0.42). The 7th shuttle of the test (280 m), corresponding to 2.5 min, was identified as the inflection point between the two phases. Also, absolute heart rate at the 7th shuttle decreased progressively throughout the year (185 ± 9, 183 ± 10, and 179 ± 10 bpm; p < 0.05; d = 0.31–0.61). The present study provides evidence of the usefulness of a maximal as well as a submaximal version of Yo-Yo IE1 as a tool to monitor changes in aerobic fitness in pre-pubertal children.     

Negotiating contradictions: educación among Dominican transnational mothers in New York City

This paper examines how a transnational orientation shapes Dominican mothers’ contradictory attitudes towards education in New York City. Through this ethnographic study, which draws on 36 interviews, community walkabouts, and participant observations in community-led adult education classes, we show how Dominican mothers struggle with conflicting values; on the one hand, they embrace the idea of schooling for individual advancement, integration in the US, and critical thinking, while on the other hand, they regret the diminution of a collective, family orientation and respect for parents. Overall, this study shows that contradictions are not a sign of confusion or denial, but rather a struggle to transform cultural practices that satisfy multiple worlds. A deeper understanding of these contradictions could help educators and educational institutions consider how these transnational tensions motivate parent engagement and their hopes for their children’s education.     

Teachers’ academic training for literacy instruction

Literacy instruction is a powerful determinant of children’s academic and school outcomes. Teachers’ training for literacy instruction is therefore critical for children’s reading learning. The present study examined the contents of 130 courses related to literacy instruction from a representative national sample of primary teachers’ undergraduate programs (N = 81), to address the following issues: which courses, related to literacy instruction, are included in the curriculum of undergraduate training programs? Which is the weight of the courses in undergraduate programs? What are the contents of the courses? The results show that most critical features of literacy instruction are included in the course contents of most programs (e.g. phonics, theory of literature). Still, some other critical features are underrepresented (reading/writing comprehension skills) or apparently missing (assessment and intervention in reading/writing problems). Moreover, the time allocated to literacy instruction seems to be scarce. Still, wide differences across university programs and courses were found.

Between the nation and the globe: education for global mindedness in Finland

This article explores some of the tensions at the interface of nationalist and global orientations in ideals of global mindedness and global citizenship looking specifically at the Finnish context. We engage with discussions related to the social–political and historical context of national identity in Finland and outline the conceptual framework of an educational initiative related to the development of global mindedness through experiences of international mobility and partnerships. This conceptual outline presents a set of theoretical distinctions through which we seek to challenge humanist and universalist approaches to the question of (the formation of) global mindedness by arguing that the issue is neither about cognition or understanding nor about empathy and relationships but ultimately has to do with modes of existence and exposure. Similar to discussions in other small states, the historical trajectory in Finland illustrates how the encounter between the nation and the globe poses particular challenges for education as it runs the risk of reverting to ethnocentric rather than globally minded forms of national identity building. We argue that this risk cannot be addressed with the promotion of a mere understanding of or mere empathy for the other as an educational or political antidote but rather requires an existential approach.     

Neural Correlates of Face Familiarity in Institutionally Reared Children With Distinctive,Atypical Social Behavior

Although the impact of early adverse experience on neural processing of face familiarity has been studied, research has not taken into account disordered child behavior. This work compared the neural processing of familiar versus strangers' faces in 47 institutionalized children with a mean age of 54 months to determine the effects of (a) the presence versus absence of atypical social behavior and (b) inhibited versus indiscriminant atypical behavior. Results revealed a pattern of cortical hypoactivation in institutionalized children manifesting atypical social behavior and that inhibited children displayed larger neural response to a caregiver's face than to the stranger's, while indiscriminant children did not discriminate between stimuli. These findings suggest that neural correlates of face familiarity are associated with social functioning in institutionalized children.
