Countering plutocracies: increasing autonomy and accountability through culturally relevant leadership

In urban school districts across the USA there are mandates to implement zero tolerance policies. As this occurs, there is an increasing number of students, specifically students of colour, who are being jettisoned out of the educative process. When school principals have little autonomy regarding how they handle disciplinary infractions within their schools, it becomes relatively easy for them to opt out of making tough decision. The authors assert that Culturally Relevant Leadership is a framework that, if applied correctly, can help school leaders reduce the multiple school suspensions and expulsions that are occurring among students of colour.     

How Exactly Does Place Matter in Crime Analysis? Place,Space, and Spatial Heterogeneity

This article has four aims. First is to clarify the origins and different meanings of place, space, and other basic concepts in spatial analysis. The second aim is to reiterate the illogicality of the spatial homogeneity assumption in ordinary least squares (OLS) regression. An illustration of the comparison between traditional OLS and geographically weighted regression modeling is included for this purpose. The third aim is to explain that place matters in crime analysis not only when crime data are spatially clustered, but when relationships between correlates are found to be conditional upon place. The final aim is to convince criminology and criminal justice faculty to begin discussing the inclusion of spatial modeling as a compulsory topic in the curriculum.     

Mathematical development: the role of broad cognitive processes

This study investigated the role of broad cognitive processes in the development of mathematics skills among children and adolescents. Four hundred and forty-seven students (age mean [M] = 10.23 years, 73% boys and 27% girls) from an elementary school district in the US southwest participated. Structural equation modelling tests indicated that calculation complexity was predicted by long-term retrieval and working memory; calculation fluency was predicted by perceptual processing speed, phonetic coding, and visual processing; problem solving was predicted by fluid reasoning, crystallised knowledge, working memory, and perceptual processing speed. Younger students’ problem solving skills were more strongly associated with fluid reasoning skills, relative to older students. Conversely, older students’ problem solving skills were more strongly associated with crystallised knowledge skills, relative to younger students. Findings are consistent with the theoretical suggestion that broad cognitive processes play specific roles in the development of mathematical skills among children and adolescents. Implications for educational psychologists are discussed.     

Evaluating students' science notebooks as an assessment tool

The idea of using science notebooks as a classroom assessment tool is not new. There is general agreement that science notebooks allow teachers to assess students' conceptual and procedural understanding and to provide the feedback students need for improving their performance. In this study we examined the use of science notebooks as an unobtrusive assessment tool that can also be used by individuals outside the classroom (for example, school district personnel), and as a means for obtaining information about students' learning and their opportunities to learn. More specifically, in this study students' science notebooks were used as a source of data about the (a) implementation of a curriculum's intended activities, (b) students' performance, and (c) quality of teachers' feedback. Our results indicated that: (1) Students' science notebooks can be reliably scored. Unit implementation, student performance, and teacher feedback scores were highly consistent across raters and units. (2) High and positive correlations with other performance assessment scores indicated that the student performance score can be considered as an achievement indicator. And (3) low performance scores across the two units revealed that students' communication skills and understanding were far away from the maximum score and did not improve over the course of instruction during the school year. This result may be due, in part, to the fact that no teacher feedback was found in any of the students' notebooks across the six classrooms studied. This may reflect some characteristics of the teachers' assessment practices that may require further professional development.     

Relations of Children's Effortful Control and Teacher-Child Relationship Quality to School Attitudes in a Low-Income Sample

RESEARCH FINDINGS: The purpose of this study was to examine the relations of children's effortful control and quality of relationships with teachers to school attitudes longitudinally in an ethnically diverse and economically disadvantaged sample. Data were collected as part of a larger intervention project during mid-fall, winter, and late spring (ns = 823, 722, and 758, respectively) for 2 cohorts of 3- to 5-year-olds (collected during 2 different school years). Children's effortful control was assessed in the fall with parents' and teachers' reports and 2 behavioral measures. Teacher-child relationship quality was assessed mid-year with teachers' reports of closeness and conflict. Attitudes toward school were assessed in late spring using teachers' and students' reports of school avoidance and liking. Effortful control, in general, was positively correlated with teacher-child closeness and school liking and negatively correlated with conflict and school avoidance. Using structural equation modeling and controlling for sex and ethnicity, we found that effortful control was positively related to teacher-child relationship quality, which in turn was positively related to school attitudes. Furthermore, the relation of effortful control to school attitudes was mediated by teacher-child relationship quality. PRACTICE OR POLICY: Results provide evidence for the importance of relational processes that take place within the classroom context and have implications for teachers and clinicians working to increase school success in ethnic minority and low-income children.

Ranking dynamics and volatility

Scientific journals are ordered by their impact factor while countries, institutions or researchers can be ranked by their scientific production, impact or by other simple or composite indicators as in the case of university rankings. In this paper, the theoretical framework proposed in Criado, R., Garcia, E., Pedroche, F. & Romance, M. (2013). A new method for comparing rankings through complex networks: Model and analysis of competitiveness of major European soccer leagues. Chaos, 23, 043114 for football competitions is used as a starting point to define a general index describing the dynamics or its opposite, stability, of rankings. Some characteristics to study rankings, ranking dynamics measures and axioms for such indices are presented. Furthermore, the notion of volatility of elements in rankings is introduced. Our study includes rankings with ties, entrants and leavers. Finally, some worked out examples are shown.     

Feasibility and students' preliminary views on parkour in a group of primary school children

Background: Adventure education is an instructional model where students participate in adventurous activities to acquire physical, cognitive, and affective skills. It also has strong connections with cooperative learning. Parkour is a fast-growing sport practiced by thousands of youngsters all over the world. The media does not portray it as an educational content, but resourcefulness, maturity, cooperation, and respect are among its basic principles. It also appears to have a direct connection with risk-taking, self-discipline, and autonomy.

Purpose: The purpose of this paper is to assess students' ideas, views, and/or feelings after experiencing a parkour learning unit.

Participants and settings: The research project was conducted in an intact, sixth-grade physical education class in an elementary school located in the northern part of Spain. A total of 26 students with ages ranging between 11 and 12 years (mean age 11.4?±?0.6) participated in the study. There were 14 boys and 12 girls.

Data collection: At the end of the intervention programme, all participating students were asked to ‘Describe your feelings, your thoughts, and your ideas on the parkour learning unit that you just experience in physical education'.

Data analysis: MAXQDA 11, a qualitative software package, was used to assist with data management. All participants' answers were analysed via thematic content analysis and constant comparison.

Findings: Five major categories emerged from data analysis: enjoyment, fear, social skills, problem-solving skills, and integration. Our findings agree with previous researchers who believe that parkour could be considered an educational content due to all the different positive outcomes that it brings to the physical education class. It seems to promote the development of social and problem-solving skills in the students. Both are competences that should be encouraged and fostered in our youngsters. Furthermore, it is considered a fun activity, it promotes students' integration, and it teaches them how to cope with fear.

Conclusion: In contrast to popular views portrayed by the media, the sport of parkour can be a safe, educational content. School cannot turn its back on sports or contents whose popularity is rapidly increasing.     

Sprinting analysis of elite soccer players during European Champions League and UEFA Cup matches

It has been suggested that assessment of high-intensity activities during a match is a valid measure of physical performance in elite soccer. Recently, sprinting activities have been analysed in more depth. The aim of this study was to develop a detailed analysis of the sprinting activities of different playing positions during European Champions League and UEFA Cup competitions. Altogether, 717 elite outfield soccer players were evaluated throughout 2002-2006 using ProZone? (Leeds, UK). Sprinting (explosive and leading) was analysed for each playing position. To compare positional differences, a Kruskal-Wallis analysis was performed. Differences were found among positions for total number of sprints and total sprint distance covered: wide midfielders > (attackers = wide defenders) > central midfielders > central defenders (P < 0.001), as well as for explosive sprints: (wide midfielders = attackers = wide defenders) > central defenders, wide midfielders > central midfielders > central defenders and attackers = wide defenders = central midfielders (P < 0.001), and leading sprints: wide midfielders > (attackers = wide defenders) > central midfielders > central defenders (P < 0.001). For each group, there were no differences in ratio of explosive to leading sprints. Wide midfielders performed a higher number of sprints in all five distance categories than all other positions. This study showed that sprinting characteristics are influenced by position. Wide midfielders have to complete additional high-intensity activities during training sessions compared with the other positions to achieve the performance level required during the match.
