Quality In Education

Value-added models are being implemented in many states in an attempt to measure the contributions of individual teachers and schools toward students’ learning. Scores from these models are increasingly used for high-stakes purposes such as setting compensation, hiring or dismissing teachers, awarding tenure, and closing schools. The statistician W. Edwards Deming wrote extensively about improving quality in education and the damage caused by performance rankings. We examine uses and misuses of value-added models in the context of Deming’s System of Profound Knowledge, and discuss contributions a Deming-based perspective and statistical science can make to improving education.

Unbiased Estimates

The ability of school (or teacher) value-added models to provide unbiased estimates of school (or teacher) effects rests on a set of assumptions. In this article, we identify six assumptions that are required so that the estimands of such models are well defined and the models are able to recover the desired parameters from observable data. These assumptions are (1) manipulability, (2) no interference between units, (3) interval scale metric, (4) homogeneity of effects, (5) strongly ignorable assignment, and (6) functional form. We discuss the plausibility of these assumptions and the consequences of their violation. In particular, because the consequences of violations of the last three assumptions have not been assessed in prior literature, we conduct a set of simulation analyses to investigate the extent to which plausible violations of them alter inferences from value-added models. We find that modest violations of these assumptions degrade the quality of value-added estimates but that models that explicitly account for heterogeneity of school effects are less affected by violations of the other assumptions.

When interacting on a learning task, which is typical of several academic situations, individuals may experience two different motives: Understanding the problem, or showing their competences. When a conflict (confrontation of divergent propositions) emerges from this interaction, it can be solved either in an epistemic way (focused on the task) or in a relational way (focused on the social comparison of competences). The latter is believed to be detrimental for learning. Moreover, research on cooperative learning shows that when they share identical information, partners are led to compare to each other, and are less encouraged to cooperate than when they share complementary information. An epistemic vs. relational conflict vs. no conflict was provoked in dyads composed by a participant and a confederate, working either on identical or on complementary information (N = 122). Results showed that, if relational and epistemic conflicts both entailed more perceived interactions and divergence than the control group, only relational conflict entailed more perceived comparison activities and a less positive relationship than the control group. Epistemic conflict resulted in a more positive perceived relationship than the control group. As far as performance is concerned, relational conflict led to a worse learning than epistemic conflict, and - after a delay - than the control group. An interaction between the two variables on delayed performance showed that epistemic and relational conflicts were different only when working with complementary information. This study shows the importance of the quality of relationship when sharing information during cooperative learning, a crucial factor to be taken into account when planning educational settings at the university.

Method Approach

Innovations in health care are costly and risky, but they also provide the opportunity for hospitals to increase quality of care, to distinguish themselves from competitors and to attract patients. While numerous hospitals strive to increase their innovativeness by adopting a costly innovation leader strategy, the question of whether this actually influences the patient’s choice remains unanswered. To understand the role of innovativeness from the patient perspective, this study conceptualizes the construct of innovativeness reputation of hospitals and determines its relevance in patients’ hospital choice decisions. In the pretest, we identified six dimensions of innovativeness reputation such as progressive work procedures and value added services. We then used three different quantitative multi-criteria decision-making methods to evaluate the relative importance of innovativeness reputation in patient choice. We collected data from 355 former German patients who had undergone elective non-emergency surgery. Overall, innovativeness reputation accounts for 11.6%–16.8% of the patient decision. Innovativeness reputation has a moderate influence on hospital choice and should be taken into account by managers. Since technical innovations are costly, hospitals should use other means to enhance their innovative image. Strategies such as emphasizing value added services can enable hospitals to increase their innovativeness reputation efficiently.

Background:Objectives:Analyse the effect of secukinumab in terms of the patient´s own variables, specifically: fatigue, sleep, pain and quality of life in patients with psoriatic arthritis or spondyloarthritis.Methods:A multicentric longtitudinal observational prospective study was carried out at 6 months in patients who begin treatment with secukinumab. At the start and after 6 months the following data was collected on the outcome: pain through an visual analogue scale (VAS), fatigue using the FACIT-fatigue scale, sleeping problems using the insomnia severity index (ISI) and quality of life with the EuroQol-3L-5D and the PsAQoL.The sample can be described in terms of the distribution of the variables through measures of central tendency.It was analysed if the change after 6 months was statistically relevant using Student´s t-test for paired data in the case of FACIT, VAS, PsAQoL and ISI and chi-squared for the dimensions of the EQ-5D. The size of the effect of each of the measurements taken was calculated using Cohen’s D. the results are given grouped by disease and globally. The analysis was carried out using Stata v12 (College Station Tx, USA)Results:In table 1, the changes in the scales of normal distribution can be seen. Apart from general VAS, all the scales experience significant relevant changes. The PROs preferred by the patient with the best therapeutic response is the quality of sleep. The adjustment of the regression models does not produce changes in the results, apart from small adjustments to the condidence intervals (final column table 1). The subdomain in which the most significant change in the EQ-5D is produced is in that of pain and discomfort.Conclusion:After 6 months patients who begin treatment with secukinumab, present with improvements in all sizes of the effects of the treatment in the various studied scales. The improvement achieves global and generalised statistical significance after 6 months of study. The greatest effect is on sleep, quality of life and fatigue.The measurements of the outcomes reported by the patients are a clinical value added to our objective evaluations of the health and activity of the disease, and allow us, in a more integrated and comprehensive manner, to undertake a more exact and close evaluation of their state of health and wellbeing.Disclosure of Interests:JUAN JOSE LERMA: None declared, Antonio Gracia: None declared, Antonio Perez: None declared, Amalia Rueda: None declared, Clara Molina: None declared, M.

The Impact

State policy makers are constantly looking for ways to improve teacher quality. An oft tried method is to increase the rigor of licensure exams. This study utilizes state administrative data from Arkansas to determine whether raising the cut-scores on licensure exams would improve the quality of the teacher workforce. In addition, the study explores the trade-offs of such a policy decision. It is concluded that raising the required passing score on the Praxis II would increase the quality of the teacher workforce, as measured by value-added student achievement. This change, however, would be accompanied with an important trade-off as it would reduce the number of minority teachers and potentially lead to negative outcomes in disadvantaged schools.

The study is devoted to the analysis of the efficiency of use and the effectiveness of disclosing the intellectual capital (IC) of a trading company operating in the market of the Russian Federation. The subject of the research is an assessment of the quality of disclosure of information about the IC company involved in the creation of financial results of activities and the growth of the company’s value. The study examines the assessment of IC and the search for links between the involvement of IC in the formation of the financial result of a trading company and the degree of its reflection in the company’s annual reports. Methods of using intellectual value-added coefficients (VAIC) such as the trademark logo (written as ™), Calculated Intangible Value (CIV) and content analysis of the company’s annual reports are used to assess the IC and its elements. The influence of IC and its components, on the financial results of a trading company are also investigated and calculated using various methods. It is shown that there are no statistically significant relationships between the assessments of IC and its elements obtained using financial ratios, and those obtained using content analysis. This indicates that the opinions and assessments of the heads of a trading company regarding IC are formed regardless of the size of IC involved in the formation of economic results and testifies to the absence of an effective investment management policy in the studied company. Some of the results obtained confirm the trends in IC structures previously observed for companies in other industries. The results also indicate that the existing system for preparing annual reports does not sufficiently consider the size, dynamics and efficiency of using the intangible assets of a trading company. The results of this study are likely to be useful to management and academics.

PurposeThrough a two-stage survey, this paper examines how researchers judge the quality of answers on ResearchGate Q&A, an academic social networking site.Design/methodology/approachIn the first-stage survey, 15 researchers from Library and Information Science (LIS) judged the quality of 157 answers to 15 questions and reported the criteria that they had used. The content of their reports was analyzed, and the results were merged with relevant criteria from the literature to form the second-stage survey questionnaire. This questionnaire was then completed by researchers recognized as accomplished at identifying high-quality LIS answers on ResearchGate Q&A.FindingsMost of the identified quality criteria for academic answers—such as relevance, completeness, and verifiability—have previously been found applicable to generic answers. The authors also found other criteria, such as comprehensiveness, the answerer's scholarship, and value-added. Providing opinions was found to be the most important criterion, followed by completeness and value-added.Originality/valueThe findings here show the importance of studying the quality of answers on academic social Q&A platforms and reveal unique considerations for the design of such systems.
