Explaining calibration accuracy in classroom contexts: the effects of incentives, reflection, and explanatory style

A 2 × 2 quasi-experimental design was used to investigate the impact of extrinsic incentives and reflection on students’ calibration of exam performance. We further examined the relationships among attributional style, performance, and calibration judgments. Participants were 137 college students enrolled in an educational psychology course. Results differed as a function of exam performance. Higher-performing students were very accurate in their calibration and did not show significant improvements across a semester-length course. Attributional style did not significantly contribute to their calibration judgments. Lower-performing students, however, were less accurate in their calibration, and students in the incentives condition showed significant increases in calibration. Beyond exam scores, attributional style constructs were significant predictors of calibration judgments for these students. The constructs targeting study and social variables accounted for most of the additional explained variance. The qualitative data also revealed differences by performance level in open-ended explanations for calibration judgments.     

Online disclosure of university social responsibility: a comparative study of public and private US universities

Public and private universities tasked with incorporating principles of social responsibility (SR) into their activities face the multiple challenges of addressing expectations of diverse stakeholders, establishing mechanisms for dialogue, and achieving greater information transparency. This article has two goals: first, to analyze whether SR has become an essential element in activities associated with university accountability, information transparency, and the use of the Internet; second, to analyze whether SR is used by universities as a differentiating factor in relation to their status. A comparative study of public and private US universities shows that neither is strongly committed to the online disclosure of SR information, including in relation to sustainability-related activities. Moreover, there is a uniformity in the accountability activities of both university types, suggesting that the challenges are not being faced, and SR is not being used as a differentiating factor in the pursuit of positional or competitive advantage.     

Regulation as both enabler of technology use and global competitive tool: The Gibraltar case

Distributed ledger technologies (DLTs) such as Blockchain appear to have disruptive economic potential to traditional finance-sector and non-financial markets as the success of crypto currencies demonstrates. While traditional financial and securities markets are highly regulated, DLT transactions and exchanges have so far widely remained unregulated, which potentially poses major threats to individual investors and, via money laundering, terrorist financing, and tax evasion, to society at large. Governments have been taking different approaches to monitoring and regulating the fledgling DLT provision arena. However, the small jurisdiction of Gibraltar, an affluent self-governed and self-financed British overseas territory with a population of 34,000 at the Southern tip of the Iberian Peninsula has taken a proactive approach. What makes this case stand out is that Gibraltar is not only is the first jurisdiction worldwide to regulate general DLT provision, but it is rather using the regulation as a competitive tool and a means for creating new public value. The study inquires the potential benefits and challenges to this particular approach to DLT provision regulation, and it investigates and presents the various facets of public value generation, which might serve as a poster child for fast and smart regulation in the digital age.     

Do self-efficacy,incentives and confidence in public speaking influence how students self-assess? / ¿Influyen la autoeficacia,los incentivos y la confianza para hablar en público en cómo se autoevalúan los estudiantes?

The development of a critical spirit as well as the capacity to self-assess and oral presentation competence are essential in relation to students’ future employability. This study examines the influence of confidence, self-efficacy and the existence of incentives on student self-assessments of their oral presentation competence during an educational activity, taking into account the students’ gender. Data from 201 self-assessments was analysed using different statistical techniques. The results show that the existence of rewards is the only variable that has a significant influence on the self-assessment of male students, while those of female students are determined, above all, by their self-efficacy. The results suggest the need to increase student training on self-assessment, taking these differences into account. They also highlight the need to implement initiatives aimed at improving speakers’ confidence in public speaking as well as self-efficacy levels.     

Ad-libitum drinking and performance during a 40-km cycling time trial in the heat

The aim of this study was to investigate if drinking ad-libitum can counteract potential negative effects of a hypohydrated start caused by fluid restriction during a 40-km time trial (TT) in the heat. Twelve trained males performed one 40-km cycling TT euhydrated (EU: no water during the TT) and two 40-km cycling TTs hypohydrated. During one hypohydrated trial no fluid was ingested (HYPO), during the other trial ad-libitum water ingestion was allowed (FLUID). Ambient temperature was 35.2 ± 0.2°C, relative humidity 51 ± 3% and airflow 7 m·s^?1. Body mass (BM) was determined at the start of the test, and before and after the TT. During the TT, power output, heart rate (HR), gastrointestinal temperature, mean skin temperature, rating of perceived exertion (RPE), thermal sensation, thermal comfort and thirst sensation were measured. Prior to the start of the TT, BM was 1.2% lower in HYPO and FLUID compared to EU. During the TT, BM loss in FLUID was lower compared to EU and HYPO (1.0 ± 0.8%, 2.7 ± 0.2% and 2.6 ± 0.3%, respectively). Hydration status had no effect on power output (EU: 223 ± 32 W, HYPO: 217 ± 39 W, FLUID: 224 ± 35 W), HR, gastrointestinal temperature, mean skin temperature, RPE, thermal sensation and thermal comfort. Thirst sensation was higher in HYPO than in EU and FLUID. It was concluded that hypohydration did not adversely affect performance during a 40-km cycling TT in the heat. Therefore, whether or not participants consumed fluid during exercise did not influence their TT performance.     

Between Transaction and Transformation: The Role of School Principals as Education Leaders in Spain

Spain is, together with Portugal, the only OECD country where school principals are democratically elected from the teaching staff of each primary and secondary school by a School Council, where all members of the school community are represented. While this unique feature of the Spanish system entails many promises in terms of deep democracy and, equally important, the potential legitimacy of change promoted by school leaders, the reality seems to be somewhat less romantic. This paper explores the limitations and constraints faced by school principals in Spain to actually perform their role as school leaders in primary and secondary schools. Based on a major study that we carried out for the National Institute for Quality and Evaluation (INCE) in 2002, involving more than 20,000 questionnaires and 30 Focus Groups (with teachers, principals, school inspectors, administrators, education experts and parents), the paper deals with the impact of leadership on school improvement and change, especially as far as teaching and learning processes are concerned. Despite their democratic legitimacy, or perhaps precisely because of its unexpected effects, the elected principal in Spain faces constraints which de facto position himself or herself between a practice of permanent transaction with colleagues and the mounting pressure of transformation and accountability coming from outside the school. Results from this research suggest that such constraints are determining that the practice of school leadership in Spain is management and maintenance-oriented rather than change-oriented, thus casting doubts about the very model of school leadership.     

The effects of individual or group guidelines on the calibration accuracy and achievement of high school biology students

A 2 × 2 factorial design was employed in a quasi-experiment to investigate the effects of guidelines in group or individual settings on the calibration accuracy and achievement of 82 high school biology students. Significant main effects indicated that calibration practice with guidelines and practice in group settings increased prediction and postdiction accuracy. A significant interaction showed that students who practiced calibration in groups using guidelines showed the greatest accuracy in their predictions and postdictions. Students in the guidelines condition and in the group setting condition had significantly higher achievement scores. The findings of this study suggest that the use of guidelines and group settings can promote calibration accuracy and achievement in high school biology courses.     

Can Providing Rubrics for Writing Tasks Improve Developing Writers' Calibration Accuracy?

Rubric-referenced calibration and the interaction between writing achievement and calibration, a measure of the relationship between one's performance and the accuracy of one's judgments, were investigated. Undergraduate students (N = 596) were assigned to one of three calibration conditions: (a) global, (b) global and general criteria, or (c) global and detailed criteria. Students in all three conditions provided global predictions and postdictions of essay exam scores. Although calibration judgments by condition did not affect calibration accuracy overall, statistically significant main effects were found between calibration accuracy by criteria and prior achievement. High achievers made more-accurate predictions and postdictions by criteria than low achievers. Regardless of achievement level, those students in the detailed rubric condition had higher postdictive accuracy for the organization criteria than did students in the general rubric condition.
