Pros and cons gamification and gaming in classroom

The aim of the current work is to assess the challenges that gamification in education are facing nowadays. Benefits and disadvantages of using gamification in classroom are both discussed to offer a clearer view on the impact of using gamification within learning process. Exploratory study cases are provided to investigate the relation between motivation and engagement of the students and gamification in training. Following this idea, a survey was conducted to assess how students behavior and motivation is affected by introducing a single, specific gamification element during a semester learning process. To stimulate competition among students, a ranking type plugin was introduced within the university learning management system used for extramural education. The results prove that motivation decreases by comparison to the previous semester.Comment: 7 pages, 3 figure

Beyond model answers: learners’ perceptions of self-assessment materials in e-learning applications

The importance of feedback as an aid to self‐assessment is widely acknowledged. A common form of feedback that is used widely in e‐learning is the use of model answers. However, model answers are deficient in many respects. In particular, the notion of a ‘model’ answer implies the existence of a single correct answer applicable across multiple contexts with no scope for permissible variation. This reductive assumption is rarely the case with complex problems that are supposed to test students’ higher‐order learning. Nevertheless, the challenge remains of how to support students as they assess their own performance using model answers and other forms of non‐verificational ‘feedback’. To explore this challenge, the research investigated a management development e‐learning application and investigated the effectiveness of model answers that followed problem‐based questions. The research was exploratory, using semi‐structured interviews with 29 adult learners employed in a global organisation. Given interviewees’ generally negative perceptions of the model‐answers, they were asked to describe their ideal form of self‐assessment materials, and to evaluate nine alternative designs. The results suggest that, as support for higher‐order learning, self‐assessment materials that merely present an idealised model answer are inadequate. As alternatives, learners preferred materials that helped them understand what behaviours to avoid (and not just ‘do’), how to think through the problem (i.e. critical thinking skills), and the key issues that provide a framework for thinking. These findings have broader relevance within higher education, particularly in postgraduate programmes for business students where the importance of prior business experience is emphasised and the profile of students is similar to that of the participants in this research

Voter Information in the Digital Age: Grading State Election Websites

Voter Information in the Digital Age: Grading State Election Websites examines the extent to which state election websites provide voters with sufficient information to make informed choices. The report assesses the quantity and quality of candidate and ballot measure information offered by the 50 state and District of Columbia election websites and ranks them from one to 51. It recommends a number of best practices currently used by some state or local jurisdictions, as well as innovations on other websites that are used rarely or not at all on state election websites. The authors recommend that states follow new technologies and trends in information delivery and design, and offer voters a full range of candidate and ballot information in innovative formats and media

The Reproducibility of Lists of Differentially Expressed Genes in Microarray Studies

Reproducibility is a fundamental requirement in scientific experiments and clinical contexts. Recent publications raise concerns about the reliability of microarray technology because of the apparent lack of agreement between lists of differentially expressed genes (DEGs). In this study we demonstrate that (1) such discordance may stem from ranking and selecting DEGs solely by statistical significance (P) derived from widely used simple t-tests; (2) when fold change (FC) is used as the ranking criterion, the lists become much more reproducible, especially when fewer genes are selected; and (3) the instability of short DEG lists based on P cutoffs is an expected mathematical consequence of the high variability of the t-values. We recommend the use of FC ranking plus a non-stringent P cutoff as a baseline practice in order to generate more reproducible DEG lists. The FC criterion enhances reproducibility while the P criterion balances sensitivity and specificity

Screening analysis and selection of emission reduction concepts for intermittent combustion aircraft engines

An analysis was conducted to screen, evaluate, and select three engine exhaust emission reduction concepts from a group of 14 candidate alternatives. A comprehensive literature search was conducted to survey the emission reduction technology state-of-the-art and establish contact with firms working on intermittent combustion engine development and pollution reduction problems. Concept development, advantages, disadvantages, and expected emission reduction responses are stated. A set of cost effectiveness criteria was developed, appraised for relative importance, and traded off against each concept so that its merit could be determined. A decision model was used to aid the evaluators in managing the criteria, making consistent judgements, calculating merit scores, and ranking the concepts. An Improved Fuel Injection System, Improved Cooling Combustion Chamber, and a Variable Timing Ignition System were recommended to NASA for approval and further concept development. An alternate concept, Air Injection, was also recommended

STUDY ON PROS AND CONS ARMY-POLICE ACTIVELY APPOINTED AS REGIONAL HEAD

This study will identify the pros and cons of active ARMY/POLICE being appointed as regional heads in 2022. In its journey, Indonesia has changed in organizing general elections; from the beginning, the public was allowed to vote for candidates from 2004 to the present. Ahead of the Simultaneous Regional Head Elections in 2024, several regions in the country will experience a leadership vacancy due to the expiration of the terms of office of governors, and regents/mayors starting in 2022. To fill the vacancy in leadership positions, the government can appoint an official until simultaneous regional elections are held in November 2024. This becomes a problem because the appointment of active TNI-Polri officers as acting (Pj) regional heads has caused a polemic. This study uses qualitative research using secondary data from news and journals related to the research. The results of the study indicate that some support this, it can be done with a note that the active TNI/Polri in office must still be supervised, and the positions occupied are equivalent to their duties. However, not a few refuse because this can reduce the value of democracy, and the TNI/Polri, which should focus on state security, will bring back the Dual function (dwifungsi) of the Armed Forces, which can disrupt the political system in Indonesia

Does Consistency Predict Accuracy of Beliefs?: Economists Surveyed About PSA

Subjective beliefs and behavior regarding the Prostate Specific Antigen (PSA) test for prostate cancer were surveyed among attendees of the 2006 meeting of the American Economic Association. Logical inconsistency was measured in percentage deviations from a restriction imposed by Bayes’ Rule on pairs of conditional beliefs. Economists with inconsistent beliefs tended to be more accurate than average, and consistent Bayesians were substantially less accurate. Within a loss function framework, we look for and cannot find evidence that inconsistent beliefs cause economic losses. Subjective beliefs about cancer risks do not predict PSA testing decisions, but social influences do.logical consistency, predictive accuracy, elicitation, non-Bayesian, ecological rationality
