Measuring Relational Reasoning

Relational reasoning is the foundational cognitive ability to discern meaningful patterns within an informational stream, but its reliable and valid measurement remains problematic. In this investigation, the measurement of relational reasoning unfolded in three stages. Stage 1 entailed the establishment of a research-based conceptualization of the construct and the development of a corresponding Test of Relational Reasoning (TORR). Stage 2 focused on the reliability and validity of data from the TORR. Analyses showed the data from the TORR to be reliable indicators of students' ability to reason relationally, and TORR performance predicted students' performance on SAT verbal and math problems. Stage 3 examined the underlying structure of the construct through Confirmatory Factor Analysis (CFA). Of the three CFA models tested, models with dedicated factors for analogical, anomalous, antinomous, and antithetical reasoning were deemed the best fit for the data.     

‘I Saw Angry People and Broken Statues’: Historical Empathy in Secondary History Education

Tasks which invite students to identify with historical actors and describe their perspectives are a common phenomenon in history education. The aim of this study is to explore the differences in students’ answers when completing a writing task in first person (‘imagine you are in the past’) or in third person (‘imagine someone in the past’), or a task in which such imagination is not explicitly asked. Furthermore we investigated the effects of the type of task on topic knowledge and situational interest. Students in Dutch secondary education (N = 254) participated by completing a task on the Dutch Iconoclasm. Our analysis of student answers focused on aspects of historical empathy: historical contextualization, affective elements and perspective taking.

Results were that all students gained some knowledge from the task, regardless of the type of task they completed. Students’ situational interest also did not differ between the three tasks. However, students’ written work showed that the first- and third-person writing tasks stimulated students to imagine concrete details of the past and emotions of historical actors. Students who were not explicitly asked to imagine themselves or someone in the past included more perspectives into their writings. Students who completed the task in first person tended to show more presentism and moral judgements of the past than students who completed a task in third person.     

Giving priority to evidence in science teaching: A first‐year elementary teacher's specialized practices and knowledge

The purpose of this qualitative case study was to examine the nature of a first‐year elementary teacher's specialized practices and knowledge for giving priority to evidence in science teaching and to explore the possible sources from which this knowledge was generated. Data included three audiotaped interviews, six videotaped classroom observations, lesson plans, and samples of students' work. The findings of this study reveal that the teacher gave priority to evidence by frequently engaging students in collecting evidence through observations and investigations, recording and representing evidence, and using that evidence to construct explanations. The findings of this study also illustrate that critical experiences during preparation to teach and specific university coursework acted as sources through which the teacher's specialized knowledge for giving priority to evidence was generated. © 2005 Wiley Periodicals, Inc.

Children's Individual Experiences in Early Care and Education: Relations With Overall Classroom Quality and Children's School Readiness

This study examined relations among children's individual experiences, global classroom quality, and school readiness. Preschool children from low-income backgrounds (N = 138; M = 62.16 months; SD = 3.93; range = 55?70) were observed in their early care and education settings, and their language and cognitive skills were assessed. Research Findings: Individual children in classrooms with small group sizes had higher quality individual experiences even though global classroom quality was not necessarily better. Higher levels of global classroom quality did not ensure that every child in the classroom was engaged fully in available interactions and activities. Children with disabilities were generally enrolled in classrooms with higher global quality and had higher quality individual experiences than those without disabilities; however, children without disabilities enrolled in these inclusive classrooms did not necessarily have a higher level of individual experiences than those in non-inclusive classrooms. Children's individual experiences and the global quality of their classrooms were associated with their social skills. Only the quality of children's individual experiences was found to be related to the quality of their relationships with teachers. Practice or Policy: Ratings of children's individual experiences provide information beyond that provided by global ratings of classroom quality and have potential for informing efforts to individualize educational programs.     

Generalizable aspects of the development of expertise in ballet across countries and cultures: a perspective from the expert-performance approach

The expert-performance approach guided the collection of survey data on the developmental history of elite professional ballet dancers from three different countries/cultures (USA, Mexico, and Russia). The level of ballet expertise attained by age 18 was found to be uniquely predicted by only two factors, namely the total number of accumulated hours of dance practice through age 17 and the age of first having the “idea of becoming a professional dancer.” Older starting ages were associated with a more rapid increase of weekly training, so starting ages were not correlated with amount of practice accumulated at age 17 or attained ballet performance by age 18. Different detailed developmental paths leading to elite ballet performance are described and their theoretical implications discussed.     

Uncertainty and previvors’ cancer risk management: understanding the decision-making process

Women who test positive for a BRCA genetic mutation, but who have not been diagnosed, or 'previvors,' experience intense, chronological risk-related uncertainty. Women’s risk management medical decisions can be a way to manage their uncertainty, but little is known about how uncertainty informs their decision or how uncertainty is impacted by these medical decisions. Using an uncertainty management theoretical lens, we interviewed 46 previvors about their decision-making process. A thematic analysis revealed two uncertainty management (i.e., risk-reducing) decision-making pathways (preventive surgery and increased surveillance) with each pathway encompassing a three-part process of 1) uncertainty appraisal, 2) medical decision (i.e., uncertainty management strategy), and 3) outcomes. The findings advance theoretical thinking about uncertainty and risk management as an ongoing, distressful chronic experience, and highlight the importance of life-span phenomena in women’s decision-making process. Based on the findings, we constructed a translational tool to aid genetic counselors and previvors facing these medical decisions.     

Cloudy with a Chance of Open Source: Open Source Integrated Library Systems and Cloud Computing in Academic Law Libraries

Integrated library systems (ILSs) have been fundamental to library workflow in both technical services and public services for decades. However, many of the proprietary ILSs currently on the market do not provide law libraries with the flexibility and adaptability necessary to keep pace with advances in technology. Some law libraries are considering abandoning proprietary ILSs and implementing one of the nascent open source ILSs that have sprung up in the last few years. As the lines blur between hardware and software, many organizations are trading in-house information technology infrastructure and personnel for full-service cloud hosting. This article examines these trends for those contemplating a move to an open source ILS and/or cloud computing.     

On the allocation of resources for secondary schools

This paper studies the optimal allocation of resources – in terms of school management, teachers, supporting employees and materials – in secondary schools. We use a flexible budget constrained output distance function model to estimate both technical and allocative efficiency scores for 448 Dutch secondary schools between 2002 and 2007. The results indicate that the average technical efficiency amounts to about 78 percent, implying that, with the given resources, schools could improve students’ educational performance by 28 percent. In terms of allocative efficiency, we estimate a 0.65 percent overutilization of teachers while management and supporting personnel are underutilized. The outcomes indicate that, despite the significant variation among schools, the average school is close to the optimal allocation of teachers.     

‘Getting more comfortable in an uncomfortable space’: learning to become an activist researcher in a socially vulnerable sport context

Activist research engages all participants as co-researchers in order to challenge the status quo in hopes of creating spaces in which they will actively participate in their education and feel responsible for their own and others’ learning. There are a number of challenges that researchers might face when engaging in activist research with co-researchers. In that sense, researchers must be open to multiple perspectives and critical attitudes in order to negotiate the challenges that arise in the process. This paper describes the challenges that the lead author faced in learning to become an activist researcher in a socially vulnerable sport context and how these challenges were negotiated. The lead author, supervised by the second author, conducted a six month activist research study in a soccer program in a socially and economically disadvantaged neighborhood in Brazil. Participants included two researchers (lead and second authors), 17 young people, four coaches, a pedagogic coordinator and a social worker as co-researchers. Multiple sources of data were collected, including 38 field journal/observations and audio records of: 18 youth work sessions, 16 coaches’ work sessions, three combined coaches and youth work sessions, and 37 meetings between the lead author and the second author. By using an activist approach four challenges were identified and negotiated: learning to become more comfortable with an activist approach, helping young people to articulate what they know and the researcher to see what they say, valuing co-researchers’ knowledge, and negotiating the culture of sport. We argue that challenges are essential, necessary and significant in an activist research project in order to transform ourselves as researchers and our relationship with others.     

An unexpected world population variation of MCT1 polymorphism 1470T > A involved in lactate transport

A common missense mutation (1470T > A) in gene SLC16A1 responsible for an amino acid substitution in protein MCT1 has been associated with differential lactate transport and hence, differences in physical performance and muscle injuries in relation to physical exercise. This study describes, for the first time, the worldwide variation of MCT1 variant 1470T > A at an intra- and inter-continental level. Two thousand five hundred and four individual genotypes of 26 populations clustered in 5 population groups have been analysed with data downloaded from the public database 1000 Genomes Phase 3 Browser. Several parameters of population differentiation and structure have been explored as well as selection signatures in the whole gene. Allele T, the common variant, shows extremely high values in Sub-Saharan African groups (frequencies 86–91%) as compared with the remaining world regions (69–49%). TT genotype also predominates in African groups, showing significant differences with the rest of world populations. In view of the evidence that the TT genotype is associated with clinical implications and a better predisposition to sprint/power performances, we suggest that the high presence of the TT genotype in African populations should be taken into account in future association studies at both medical and sports fields.
