Using context variety and students' discussions in recognizing statistical situations

We present a proposal for helping students to cope with statistical word problems related to the classification of different cases of confidence intervals. The proposal promotes an environment where students can explicitly discuss the reasons underlying their classification of cases.     

Measurement error in short-term power testing in young people

The aim of this study was to examine the consistency or reproducibility of measuring cycling peak power in children and adults. Twenty-seven pre-pubertal girls and boys and 27 female and male physical education students (age 9.8 +/- 0.5 and 24.4 +/- 4.3 years, respectively; mean +/- s) participated in the study. All participants performed five tests over 15 days and underwent a habituation session before the study. Each test included four sprints against four different braking forces. We found that braking forces of 7.5% of body weight in children and 10% of body weight in adults were too high for most of the participants to elicit maximal cycling power. Unlike the children, the physical education students improved their performance between session 1 and session 2 (1025 +/- 219 vs 1069 +/- 243 W; P < 0.001). Therefore, to obtain reproducible measures of cycling peak power, a habituation session including a complete test protocol (i.e. warm-up plus three sprints) is highly recommended. When the protocol included three sprints in children and at least two sprints in adults, measurement of cycling peak power was found to be highly reliable (test-retest coefficient of variation approximately 3%). Finally, to avoid performance fluctuations, especially over several consecutive evaluations (e.g. longitudinal studies), it is necessary to maintain high motivation in children.     

Outcome‐Based Vocational Rehabilitation: Measuring Valuable Results

ABSTRACT This case study illustrates one of the many possible ways to implement Kaufman's Organizational Elements Model (1992, 2000) for identifying and aligning organizational results and the means to achieve them. The model was applied in the context of a needs assessment effort between the Florida State University's Office for Needs Assessment & Planning (ONAP) and the Vocational Rehabilitation Program at Florida Division of Blind Services (FDBS). Conducting this study and finding data that had such radical implications for decision‐making was life altering for many of the stakeholders, who up until that point were heavily focused on processes and resources, or at best, on Micro‐level results. Appropriate actions were taken to improve the performance system, but overall, one of the most significant contributions of this project was a new‐found focus on results, valuable results, and appropriate measures of success.     

Conquest or Reconquest? Students’ Conceptions of Nation Embedded in a Historical Narrative

This article focuses on university students’ understanding of the concept of nation. First an analysis of this concept from a historiographical point of view is presented. This allows for distinguishing between different conceptions of the nation related to 3 main approaches: the romantic, the modernist, and the ethnosymbolic approaches. Based on this analysis and also taking into account present research about history education and the construction of national identities, 5 different dimensions of the concept are presented: (a) historical subject, (b) identification, (c) territory, (d) legitimate claim, and (e) general concept scheme. Qualitative individual interviews were carried out with 31 Spanish college students about a Spanish foundational historical narrative, embedding the concept of nation, called the Reconquest (711 ad–1495 ad). Results indicated that although students showed tensions in their narratives, romantic conceptions dominated most of them. Possible reasons for the existence of these views are analyzed in terms of how the concept of nation is presented in and out of school. Also, implications for teaching and learning this concept are discussed, looking at learning strategies that could improve the understanding of this concept through its 5 analyzed dimensions.
