Learning Object Oriented Programming Using Augmented Reality - A Case Study with Elementary School Students

abstract: There is a demanding need to empower students from kindergarten through high school to learn computer science and be equipped with the computational thinking skills that they need in today's technology driven world. However, introducing computer programming to students can be challenging, especially for those who aren't familiar with the nuances of code. Several popular tools are used in curriculum for K-12 students which utilize interactive and visualization approaches to engage young kids in learning computational concepts. Possibilities of using Augmented Reality (AR) in teaching programming to novices are explored in this work. In this thesis Ogmented, an AR application is designed which includes interactive learning material that covers a range of fundamental Object-Oriented Programming (OOP) concepts. This work aims to exploit the idea to learn abstract concepts via AR by capitalizing the strength of visual-aided and interactive elements. A user study with a group of elementary school students is conducted. It explored how students operated the AR application with the interactive elements and how they wrote codes to solve programming problems. It was observed that students who followed instructions while taking tutorials were successfully able to write fragments of codes in exercise modules. Irrespective of their knowledge about programming, majority of students were able to write executable code snippets for concepts they were taught with use of Ogmented. This shares an initial insight on using AR in classroom to teach abstract programming concepts.Dissertation/ThesisMasters Thesis Computer Science 201

Best Strategies for Mitigating Choice Overload

Objectives of the study As the growth in product variety and assortment continues to soar, consumers nowadays are more susceptible to choice overload. In order to attract and retain customers, retailers must take actions to mitigate the choice overload problem in their product assortments. Hence, this study aims to find out best strategies that enterprises can employ to mitigate choice overload. Academic background and methodology Prior research has mainly concentrated on proving the existence of choice overload problem as well as the effects of assortment size reduction on mitigating the problem. However, little research has been done on examining additional mitigation strategies for choice overload. Therefore, this study aims to identify further approaches that enterprises can adopt to mitigate choice overload problem by examining different assortment strategies as well as the consumer groups in experienced choice overload level. The assortment strategies examined in the study are Assortment Size Reduction, Categorization, Provision of a Default Option and Unconscious Information Processing. As for consumer groups, different groups classified by Gender, Age, Education and Continent were compared. The thesis employed a behavioral experiment to examine participants’ degree of experienced choice overload when making their decisions in different assortment conditions. Participants were assigned to 9 different assortment scenarios corresponding to different combinations of mitigation approaches. After making their decision in the assortment, they were asked to evaluate their choice overload based on a set of statements. The experiment results revealed the effectiveness of different mitigation approaches and the differences among consumer groups in experienced choice overload. Findings and conclusion First, the experiment confirmed the existence of choice overload effect. Second, the experiment suggested the effectiveness of assortment strategies. Third, we uncovered that most effective mitigation strategies are Reduction of Assortment Size and Unconscious Information Processing. Fourth, the mitigation strategies were discovered to be more effective when being in combination with each other instead of being stand-alone. Finally, regarding the differences among consumer groups in experienced choice overload, those who demonstrated low levels of choice overload are men, elders and highly educated people. These results suggest various actions that enterprises should consider to mitigate choice overload in their product assortments

Prediction of Student Final Exam Performance in an Introductory Programming Course: Development and Validation of the Use of a Support Vector Machine-Regression Model

This paper presents a Support Vector Machine predictive model to determine if prior programming knowledge and completion of in-class and take home formative assessment tasks might be suitable predictors of examination performance. Student data from the academic years 2012 - 2016 for an introductory programming course was captured via ViLLE e-learning tool for analysis. The results revealed that student prior programming knowledge and assessment scores captured in a predictive model, is a good fit of the data. However, while overall success of the model is significant, predictions on identifying at-risk students is neither high nor low and that persuaded us to include two more research questions. However, our preliminary post analysis on these test results show that on average students who secured less than 70% in formative assessment scores with little or basic prior programming knowledge in programming may fail in the final programming exam and increase the prediction accuracy in identifying at-risk students from 46% to nearly 63%. Hence, these results provide immediate information for programming course instructors and students to enhance teaching and learning process.</p

Investigating the factors affecting customers’ trust and acceptance of online banking: The case of Saudi Arabia

This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonThe need for online banking technology in the banking industry is important to allow financial institutions to serve their customers worldwide, without having the need to be present in person or face-to-face to benefit from the service. Despite the investment in informational technology and information system infrastructure by Saudi Arabian financial institutions, the Saudi banks have lagged their Western counterparts when it comes to provision of online banking services. Given a relatively recent adoption of online banking in Saudi Arabia, consumer trust in online banking is a critical challenge facing bank managers, warranting further research. The aim of this research is to develop a framework to improve consumer trust toward online banking services and its affect consumer intentions to use the online banking service and e-WOM. The literature included the assessment of relevant theories including social cognitive theory, technology acceptance model and commitment trust theory. These theories formed the basis of formulation of research framework, including development of 12 research hypotheses. Perceived usefulness, perceived ease of use, relationship termination cost, shared value, communication, privacy and demographic factors all have an important role in influencing the extent of trust and the subsequent intention of customers to engage in and use online banking services provided by the financial institutions. When it comes to the literature gap, there remains a relative lack of existence of research on the subject of consumer trust in online banking within Saudi Arabia (Zhou, 2012; Alanezi and Brooks, 2014; AL-Malkawi et al., 2016), which presents a gap in the literature warranting further research. Moreover, most of the prior research on the subject of consumer trust in online banking has concentrated on the information cues such as reputation and information quality (Montazemi and Qahri-Saremi, 2015). This is alongside relatively little attention given to other factors such as perceived usefulness, ease of use, shared value, and privacy/security, which are crucial factors in online banking services (Fatima, 2011; Aloul., 2012; Montazemi and Qahri-Saremi, 2015). Regarding methodology, the positivist research philosophy, deductive approach, survey questionnaire and quantitative data collection and analysis techniques were undertaken. A key rationale for selection of such a methodology is the review of relevant literature, which led to development of research hypotheses that are tested through the survey technique, which is consistent with positivist and deductive research approach. The survey questionnaire request was sent online to 800 research participants (users of online services in Saudi Arabia). Out of these 800, 585 responded (indicating a response rate of an impressive 73%). The response rate was improved through giving regular reminders to the research participants who had not responded to the survey earlier. The findings of this research support the argument that trust in e-bank website play an important role in maintaining long term relationship with customers. Therefore, online banks who deal with their customers in a confidential, transparent and honest manner and ultimately protect the consumers‘ interests are likely to contribute to greater adoption of online banking by customers in Saudi Arabia. Furthermore, it is also concluded that perceived ease of use, trust in online banking website, trust in technology, relationship termination cost, privacy/security, shared value, and communication have positive and significant effect on customer trust in e-bank website, intention to use online banking, and e-WOM
