Gamifying Foundational STEM Skills

© 2016 IEEE. University education has always required numeracy and literacy to underpin development of higher-level knowledge and skills. In many countries, education policies have often followed transitory fashions, both in mathematics and language education, enfeebling potentially generations of their youth. The use of technological innovations can amplify or hinder the development of foundation skills, and for digital natives this is their norm. In this paper we address this issue by describing the development of a gamified approach to learning, aimed at reinforcing and developing the fundamental knowledge of basic elements, whilst enhancing more conceptual skills, such as pattern recognition and hyper search strategies. These latter are increasingly important in the digital world. We focus here on numeracy skills, illustrating both how rote learning is practiced \u27incidentally\u27 as strategic pattern recognition is developed in a game context. We detail how the application can be used diagnostically and normatively as it is mapped to outcome based educational levels and standards. We then discuss the extension of the approach to language development, and show implications for educational information systems design

Interface development for a gaze-controlled reading support application

© 2015 IEEE. This paper describes development of an application to support the digital reading of academic texts by non-native speakers, in particular Emirati University students. Text interaction is unobtrusively controlled by gaze, tracked at word level, offering user-directed support and reporting data useful for reading assessment at individual and aggregate levels. After briefly outlining some specific reading difficulties we describe specific technical requirements and features, the application design process, and results from iterative evaluation of prototypes with target user representatives

Interacting with a Chatbot-Based Advising System: Understanding the Effect of Chatbot Personality and User Gender on Behavior

Chatbots with personality have been shown to affect engagement and user subjective satisfaction. Yet, the design of most chatbots focuses on functionality and accuracy rather than an interpersonal communication style. Existing studies on personality-imbued chatbots have mostly assessed the effect of chatbot personality on user preference and satisfaction. However, the influence of chatbot personality on behavioral qualities, such as users’ trust, engagement, and perceived authenticity of the chatbots, is largely unexplored. To bridge this gap, this study contributes: (1) A detailed design of a personality-imbued chatbot used in academic advising. (2) Empirical findings of an experiment with students who interacted with three different versions of the chatbot. Each version, vetted by psychology experts, represents one of the three dominant traits, agreeableness, conscientiousness, and extraversion. The experiment focused on the effect of chatbot personality on trust, authenticity, engagement, and intention to use the chatbot. Furthermore, we assessed whether gender plays a role in students’ perception of the personality-imbued chatbots. Our findings show a positive impact of chatbot personality on perceived chatbot authenticity and intended engagement, while student gender does not play a significant role in the students’ perception of chatbots

Associated Links Among Smoking, Chronic Obstructive Pulmonary Disease, and Small Cell Lung Cancer: A Pooled Analysis in the International Lung Cancer Consortium

Background: The high relapse and mortality rate of small-cell lung cancer (SCLC) fuels the need for epidemiologic study to aid in its prevention. Methods: We included 24 studies from the ILCCO collaboration. Random-effects panel logistic regression and cubic spline regression were used to estimate the effects of smoking behaviors on SCLC risk and explore their non-linearity. Further, we explored whether the risk of smoking on SCLC was mediated through COPD. Findings: Significant dose-response relationships of SCLC risk were observed for all quantitative smoking variables. Smoking pack-years were associated with a sharper increase of SCLC risk for pack-years ranged 0 to approximately 50. The former smokers with longer cessation showed a 43%(quit_for_5-9 years) to 89%(quit_for_>= 20 years) declined SCLC risk vs. subjects who had quit smoking <5 years. Compared with non-COPD subjects, smoking behaviors showed a significantly higher effect on SCLC risk among COPD subjects, and further, COPD patients showed a 1.86-fold higher risk of SCLC. Furthermore, smoking behaviors on SCLC risk were significantly mediated through COPD which accounted for 0.70% to 7.55% of total effects. Interpretation: This is the largest pooling study that provides improved understanding of smoking on SCLC, and further demonstrates a causal pathway through COPD that warrants further experimental study
