Analysing feedback processes in an online teaching and learning environment: an exploratory study

Within the constructivist framework of online distance education the feedback process is considered a key element in teachers’ roles because it can promote the regulation of learning. Therefore, faced with the need to guide and train teachers in the kind of feedback to provide and how to provide it, we establish three aims for this research: identify the presence of feedback according to the regulation of learning required; characterise this feedback according to content (i.e. the meaning of feedback); and, finally, to explore possible relationships between feedback and the results of the teaching and learning process (i.e. students’ satisfaction and final grades). The results for a sample of 186 students, taking nine courses at the Open University of Catalonia, are discussed in the light of feedback, which is considered a central element in university teaching practice in online environments. We conclude that, in general, the presence of feedback is associated with improved levels of performance and higher levels of satisfaction with the general running of the course.     

Updating a Classic: “The Poisson Distribution and the Supreme Court” Revisited

W.A. Wallis studied vacancies in the US Supreme Court over a 96‐year period (1837–1932) and found that the distribution of the number of vacancies per year could be characterized by a Poisson model. This note updates this classic study.     

Determination of a quantitative parameter to evaluate swimming technique based on the maximal tethered swimming test

The aim of this study was to propose a new force parameter, associated with swimmers’ technique and performance. Twelve swimmers performed five repetitions of 25 m sprint crawl and a tethered swimming test with maximal effort. The parameters calculated were: the mean swimming velocity for crawl sprint, the mean propulsive force of the tethered swimming test as well as an oscillation parameter calculated from force fluctuation. The oscillation parameter evaluates the force variation around the mean force during the tethered test as a measure of swimming technique. Two parameters showed significant correlations with swimming velocity: the mean force during the tethered swimming (r = 0.85) and the product of the mean force square root and the oscillation (r = 0.86). However, the intercept coefficient was significantly different from zero only for the mean force, suggesting that although the correlation coefficient of the parameters was similar, part of the mean velocity magnitude that was not associated with the mean force was associated with the product of the mean force square root and the oscillation. Thus, force fluctuation during tethered swimming can be used as a quantitative index of swimmers’ technique.     

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.     

Attachment,Acculturation, and Psychosomatic Complaints Among Hispanic American University Students

This study investigated adult attachment and acculturation frameworks of reported psychosomatic complaints related to perceived discrimination among a sample of Latino/Hispanic university students (N = 160). The model supported by the data suggests that attachment anxiety, acculturation toward the dominant cultural norms, and adherence to Latino/Hispanic cultural beliefs are important factors for perceived discrimination and psychosomatic complaints experienced by Latino/Hispanic students. Counseling implications and future research directions are discussed.     

Homework and academic achievement across Spanish Compulsory Education

Homework (HW) is one of the most common school-related activities among parents, students and teachers. However, the need to assign HW to students has been extensively debated. The present investigation examines the relationship between specific HW variables (i.e. amount of HW completed, time spent on HW and perceived quality of HW time management) and academic achievement, while controlling for students’ gender and grade level. Participants included 454 students (ranging from 10 to 16?years of age) from three schools in northern Spain. A multivariate analyses of variance and path analyses showed that the amount of HW completed decreased with increased schooling, as did students’ perceived quality of HW time management. Data from hierarchical regression analyses completed by path analyses provided evidence that time spent on HW conjointly with perceived quality of HW time management explains how academic achievement is mediated by the amount of HW completed. These findings deepen the understanding of the complex impact of time spent on HW and on academic achievement.     

An improved robust stabilization method for discrete-time fuzzy systems with time-varying delays

This note focuses on the robust stabilization of discrete-time fuzzy uncertain systems with time-varying delays under a delayed nonparallel distributed compensation scheme. The key idea is twofold: first, the linear matrix inequalities (LMI) proposed here are shown to generalize some previous similar results available in recent literature, and second, the design of control parameters is decoupled from the proposed fuzzy-basis dependent Lyapunov–Krasovskii functional (FBDLKF) by means of Finsler?s lemma. Finally, a numerical example is provided to illustrate the effectiveness of this method.
