abstract: Guitar Hero III and similar games potentially offer a vehicle for improvement of musical rhythmic accuracy with training delivered in both visual and auditory formats and by use of its novel guitar-shaped interface; however, some theories regarding multimedia learning suggest sound is a possible source of extraneous cognitive load while playing so players may score higher with sound turned off. Also, existing studies have shown that differences in the physical format of interfaces affect learning outcomes. This study sought to determine whether (a) the game’s audio content affects rhythmic accuracy, and (b) the type of game controller used affects learning of rhythmic accuracy. One hundred participants were randomly assigned in approximately equal numbers (ns = 25) to the four cells of a 2x2 between-subjects design. The first variable was the audio content of the game with two levels: on or off. The second variable was the type of game controller: the standard guitar-style controller or tablet interface. Participants across all conditions completed a pre- and post-test with a system that required them to tap along with repeated rhythmic patterns on an electronic drum pad. Statistical evidence showed better outcomes with a tablet controller with respect to input time error, reduction of extra notes played, and reduction of missed notes; however, the guitar-style controller produced superior outcomes in terms of avoiding missed notes and was associated with higher satisfaction by participants. When audio was present better outcomes were achieved at multiple factor-levels of reduction of missed responses, but superior outcomes in input time error were seen without audio. There was no evidence to suggest an interaction between controller type and the presence or absence of audio. / Dissertation/Thesis / Doctoral Dissertation Educational Technology 2017

Live simulations play an important role in allowing users to practice and develop skills they learn in training. Although live simulations are playing an increasingly important role in training, ways to improve them are not well understood or documented. In order to improve the efficacy of live simulation and maximize results from funds spent on training; this research examines the relationship between the affective variables of the participants and their performance in the live simulation. Prior to participating in the instructor development live simulation used in this study two training preference scales were administered to a group of trainees. These scales measured the trainees’ locus of control and immersion tendencies. During the live simulation the trainees’ performance was evaluated by a panel of expert observers. The trainees also self-reported their performance through the use of a self-rating instrument. Analysis of the data revealed significant positive correlations between the trainees’ internal locus of control and their performance in the simulation, both self-reported (p=0.026) and as reported by the expert observers (p=0.033). The correlation between immersion tendency scores and performance in the live simulation were mixed; while not always statistically significant they did reveal some slight positive correlation. This research did provide a number of lessons learned and implications for instructional and simulation developers wishing to employ live simulation in a training environment. These include performance of sub-populations within the greater population of subjects, consideration of roles assigned to participants, and the need to increase presence within the live simulation. Application of these lessons learned can reduce training costs and/or improve the effectiveness of live simulation in a training environment, this in turn can be of significant benefit to instructional and simulation designers. Additionally, understanding these relationships can lead iv to better assignments of roles or activities within live simulation and improve the transfer of experience from live simulation training to on the job performance. However, additional research needs to be conducted in order to make more conclusive statements regarding the most appropriate affective variable that would allow for predicting transfer of the simulated experience to the ‘real’ world, the individuals who would benefit most from live simulation, and to develop additional prescriptive methods for improving live simulation utilized in training environments.

The purpose of this study is to design, develop and evaluate an electronic performance support system (EPSS) for the crime scene investigation unit (CSI). For this purpose, a sequential explanatory strategy as a procedure of the mixed method design was used in analysis and evaluation of the EPSS. The research was composed of three main phases: analysis / design, development and implementation, and evaluation of the EPSS. In first phase composed of performance and cause analyses, the CSI Unit&rsquo / s existing information, and contributing causal performance factors based on Gilbert&rsquo / Behavior Engineering Model were explored. In performance analysis phase, official documentation of the CSI Unit was reviewed. As for cause analysis, the survey and focus group interviews were conducted to 1176 and 22 CSI officers, respectively. These data were analyzed using with both quantitative and qualitative methods to facilitate the selection of the most appropriate intervention and its components. Analyses results revealed that 14 basic influences grouped under the workplace and competency on human behavior impacted performance of the officers. Based on these results, an EPSS composed of intrinsic, extrinsic and external levels, and support components was designed and developed in the second phase. Having been implemented, the evaluation of the EPSS based on the Kirkpatrick&rsquo / Four Levels of Evaluation Model was conducted v to determine the overall impact, perceived benefits, and effectiveness of the intervention in third phase. In this phase, a survey, interviews, computer logs and a checklist were used so as to assess the accomplishment of the EPSS. While the survey and the checklist were administered to the 191 officers and 2 experts from the field, the interviews were conducted with 12 officers. Evaluation results admitted that the CSI officers&rsquo / reactions were very positive to the EPSS. While, an intrinsic support made a major contribution to their productivity, establishing standardization would be perceived as the major impact of the EPSS. Lastly, increasing identity and simplifying criminal justice system were the two main impact factors on the society that the system would influence positively.

When there s a high competitiveness model, priority is given to the highest quality and therefore quality management. Quality in this scenario is not a term restricted to the finished product, but regards to the whole transformational process of inputs and applying process transforming resources, directly including the human factor, whose participation tends to be more significant, the more intensive the processes become. This study aims to discuss how human performance contributes to the quality of products in an industry notoriously labor-intensive: the footwear industry of the state of Paraiba (PB). The most significant contribution comprises the organizations, because the analysis presented aims to bring to the attention of the managers that such phenomena occur and, more importantly, how they occur. To this end, an adaptation was proposed of the Likert Scale, which allows the classification of a situation viewed as alarming, worrying, reasonable or regular, good, and excellent or great. Moreover, it proposes dimensions, variables and indicators which address the essential requirements to achieve the goals (Quality, Human Performance Factors, and Influence on Human Performance) and questionnaires, which were applied to the managers and workers belonging to a footwear company, located in Campina Grande - PB. Further to this instrument, an on-site non-participatory observation was used as a tool for gathering further information. The results show that both, workers and managers understand the importance of the former for end product quality. However, there are significant differences of thoughts. This points to the need of aligning the thought of managers and workers more accurately, in order to improve performance in accomplishing activities, leading ultimately to: rise in quality and productivity, better profitability, and compliance with deadlines. / Os avanços tecnológicos e organizacionais estão diretamente conectados a alta competitividade do mercado em todos os setores. Neste modelo de alta competitividade, prioriza-se a qualidade absoluta e, por conseguinte, a gestão da qualidade. O termo qualidade nesse cenário não se restringe ao produto acabado, mas a todo o processo de transformação de insumos e a aplicação dos recursos transformadores do processo, incluindo diretamente o fator humano, cuja participação tende a ser mais significativa quanto mais intensivos são os processos. O presente trabalho tem como objetivo discutir como o desempenho humano contribui com a qualidade dos produtos em um setor reconhecidamente intensivo em mão de obra: o setor calçadista do Estado da Paraíba. Sua contribuição mais significativa abrange as organizações, pois as análises apresentadas visam mostrar aos seus gestores que tais fenômenos ocorrem e, mais importante, como eles ocorrem. Neste intuito, foi proposta uma adaptação da Escala de Likert, que permite a classificação de uma situação visualizada como: alarmante; preocupante; razoável ou regular; boa; e excelente ou ótima. Além disso, propõemse dimensões, variáveis e indicadores que abordam os requisitos essenciais do objetivo (Qualidade, Desempenho Humano e Fatores de Influência sobre o Desempenho Humano) e questionários, que foram aplicados junto a gestores e operários pertencentes a uma empresa calçadista, localizada no município de Campina Grande PB. Além deste instrumento, uma observação não participativa in loco foi utilizada como instrumento de coleta de informações adicionais. Os resultados encontrados demonstram que tanto operários como gestores compreendem a importância dos primeiros à qualidade, porém há diferenças expressivas de pensamentos. Isso denota a necessidade de alinhar mais precisamente pensamentos de gestores e operários, com a finalidade melhorar o desempenho no exercício de atividades; acarretando em última análise: em elevação da qualidade, produtividade, atendimento de prazos e lucratividade.

During an extravehicular activity (EVA), the role of an astronaut involves a multitude of complex tasks. Whether that task is a science experiment aboard the International Space Station, or traversing extraterrestrial terrain – attention, communication, and instruction are essential. As an aid, augmented reality (AR) can portray suit informatics and procedures within line-of-sight while minimizing attentional loss. Currently, there exists little research highlighting the human systems considerations to qualify AR systems for space suit applications. This study quantifies user interface (UI) and human performance measures for an AR prototype on the Mark III space suit. For user testing, 21 military pilots and personnel (11 men, 10 women) evaluated UI search tasks and completed a series of AR-instructed EVA dexterity tasks in an elevated luminosity, background clutter, and workload scenario. UI results suggest correlations for readability and usability; whereas, human performance results provide situational awareness, workload, and task performance data.
